三、阅读理解
The bones of what is believed to be the largest known marine reptile (爬行动物) were found on a beach by a nonprofessional fossil-hunting father and daughter.
Paleontologists (古生物学家) think the remains are from a giant ichthyosaur, a reptile that lived during the time of the dinosaurs. Fossilized (石化的) pieces of jawbone, some two meters long, were uncovered on the Somerset coast in May 2020, and are thought to be part of the creature that measured 25 meters long.
Justin Reynolds and his daughter Ruby made the discovery while hunting for fossils on the beach at Blue Anchor. The bones are around 202 million years old and date to the end of the Triassic Period in a time known as the Rhaetian.
Ruby, then aged 11, found a giant bone before the pair searched for more pieces together. After realizing the significance of the fossils, they approached Dr Dean Lomax, a paleontologist at the University of Manchester. Dr Lomax contacted Paul de la Salle, a fossil collector who had found a similar giant jawbone in May 2016, further along the coast at Lilstock.
Mr Reynolds said, “When Ruby and I found the first two pieces we were very excited as we realized that this was something important and unusual. When I found the back part of the jaw, I was excited because that is one of the defining parts of Paul’s earlier discovery.” Ruby added that it was so cool to discover part of this huge ichthyosaur and was very proud to have played a part in a scientific discovery like that.
Dr Lomax said, “I was amazed by the find. In 2018, my team studied and described Paul’s giant jawbone and we had hoped that one day another would come to light. This new specimen is more complete, better preserved, and shows that we now have two of these giant bones called a surangular — that has a unique shape and structure.”
1. Why did Justin Reynolds and his daughter go to the beach
A. To relax. B. To find fossils. C. To enjoy the view. D. To see reptiles.
2.Why did Justin turn to Dr Dean Lomax
A. He wanted to learn from a paleontologist.
B. He hoped to get in touch with Paul de la Salle.
C. He thought his find was of great scientific value.
D. He knew Lomax must be interested in the find.
3.Why was Ruby proud when they made the discovery
A. She made contributions to scientific study.
B. She was praised by experts in this field.
C. She might be featured on social media.
D. She learned a lot about ancient creatures.
4.What does the underlined word “specimen” in the last paragraph stand for
A. The reptile ichthyosaur.
B. The find of Paul in 2016.
C. The bones Lomax’s team studied in 2018.
D. The jawbone found by Ruby and her father.

一、易错点分析
(一) 动词-ing形式作宾语补足语
1. 动词-ing形式作宾语补足语常放在宾语后面，表示一个正在进行的主动性的动作，强调一个过程或一种状态。
2. 能用-ing形式作宾语补足语的几类动词：
(1)表示感觉和心理状态的感官动词，
常见的有see，hear，feel，smell，find，notice，observe，look at，listen to + sb.+ doing sth.(doing作宾补)
(2)表示指使意义的动词使役动词
常见的有have，set，keep，get，catch，leave +sb./ sth. + doing sth. (doing作宾补)使某人做某事
3. see，hear，feel，watch等动词之后用-ing形式和动词不定式作宾语补足语的区别：
前者表示动作正在进行，后者表示(或强调)动作的全过程。
例：We heard the telephone ringing.
We heard the telephone ring.
(二) 动词-ing形式作状语
动词的-ing形式可以作状语，修饰动词，在句中表示时间、原因、结果、条件、让步、行为方式或伴随情况等。-ing形式作时间、原因、条件、让步状语时多位于句首；作结果、伴随情况状语时常位于句末。
1. 表示时间，相当于一个时间状语从句。
Having made full preparations, we are ready for the examination.
我们已经做好了充分准备，现在可以应考了。
(= After we have made full preparation...)
2. 表示原因，相当于一个原因状语从句。
Being ill, he didn't go to school yesterday.
由于生病，他昨天没有上学。
(= Since he was ill...)
3. 表示结果，相当于一个并列谓语。

如果你努力学习，就一定能成功。
(= If you work hard at your lessons...)
5. 表示让步，相当于一个让步状语从句。
Working hard as he did, he was still unable to earn enough money to buy a car.
他虽然努力地干，但仍然挣不够买车的钱。
(= Though he worked hard as he did...)
6. 表示行为方式、伴随情况或补充说明，相当于一个并列结构。
He lay on the grass, staring at the sky for a long time.
他躺在草地上，长时间地望着天空。
(= ...and stared at the sky for a long time)
注意：非谓语动词作状语时，如提供的动词不能与句子中的主语保持一致，动词-ing形式必须拥有自己的逻辑主语，通常由名词或代词来担任，这就是独立主格结构。
例：Weather permitting, the football match will be played on Friday.
天气允许的话，足球赛将在周五举行。
(permitting 的逻辑主语是weather，而不是the football match)
二、语法填空
1. People probably cooked their food in large pots, ______ (use) twigs (细枝) to remove it.

三、阅读理解
Lots of factors contribute to how healthy a person is. Some of these are obvious, like the medical care they receive. But some less obvious factors can be even more important! Some examples include access to food, housing, healthcare, social support and education.
What good does education do to you Research shows that education can lengthen your life expectancy! Getting more education leads to better employment, higher income, and access to healthcare. And all of these improve overall health. So, people with more education tend to have higher life expectancies than people with less education.
Many studies show more education is associated with longer lives. But no one has calculated exactly how much longer or how much mortality risk goes down with each year of schooling. In other words, how does education lower a person’s risk of death Of course, everyone still dies, but a lower mortality risk means a higher chance of a long life.
We reviewed previous studies that looked at education and mortality, searching seven databases of scientific studies from around the world. We gathered all the studies on this topic published between 1980 and 2023. In total, we identified 603 studies from 59 countries. We analyzed the results from all these studies to measure how education affected mortality risk. Besides, we also looked at differences in the effect of education at different ages. Finally, we checked the effect of education across Socio-Demographic Index levels.
We found that getting more education lowers mortality risk. With each year of education, an adult’s risk of death goes down by about 2%. This effect is greater in younger adults than in older ones. But even people over 70 years old benefit from the positive effects of education! When we looked at countries at different stages of social and economic development, we didn’t find different results. This suggests that more years of schooling leads to longer lives in both rich and poor countries.
1. According to the author, education can be ___________.
A. a pathway to health B. a measure of success
C. a source of stress D. a chance for the rich
2. What does the underlined word “mortality” in paragraph 3 mean
A. Health. B. Death. C. Virtue. D. Survival.
3. What is paragraph 4 mainly about
A. The methods. B. The arguments. C. The findings. D. The suggestions.
4. What can be inferred from the last paragraph
A. People in poor countries benefit more from education.
B. The impact of education on young people is relatively greater.
C. Education does affect how long people live in different countries.
D. People in rich countries have chances to gain further education easily.
四、七选五
We live in a world where we are usually exposed to (接触) news on social media that can be scary, upsetting, or confusing. ① _________ However, as Mr. Rogers, the beloved host of a children’s show, once said, “When I was a boy and I would see scary things in the news, my mother would say to me, ‘Look for the helpers. You will always find people who are helpful.’ ”
One of the places where we can look for “the helpers” is on social media platforms. ② _________ For example, Ryan Kaji is a 9-year-old boy who runs the channel Ryan’s World. He makes videos about science experiments and games that are fun and educational for kids. He also donates to charities and causes that he cares about.
③ _________ One problem is finding reliable (可靠) and exact sources of information. Not all content on social media platforms is trustworthy. Some content creators may just want to make money from ads. Therefore, it is important to judge the reliability of the sources before we trust their content. Another challenge is keeping a healthy balance between online and offline activities. Spending too much time online can do harm to our physical health, such as causing headaches or sleep problems. Therefore, it is important to limit our screen time by doing other activities. ④ _________
Looking for helpers on social media can be a valuable way to find hope and comfort in difficulty. ⑤ _________ Then we will form our own opinions. We can also be helpers ourselves by sharing helpful content on social media that can make a difference in the world.
A. We’d better find some topics to talk about with the helper.
B. Exercising, reading, and learning art are all good choices.
C. Phones and computers have made information easier to gain.
D. They offer a lot of content that can educate or support young viewers.
E. It enables us to see things from different viewpoints and learn new things.
F. However, looking for helpers on social media also comes with some challenges.
G. Sometimes, it can be hard to deal with the negative thoughts that these events cause.

8.答案：approaching
解析：考查非谓语动词。句意：随着夏天的临近，一些学生会感到非常高兴。提示词作with复合结构中宾语summer的补足语，是非谓语动词，与其逻辑主语summer之间是主动关系，用现在分词approaching表主动和正在发生。故填approaching。
9.答案：singing

10.答案：discussing
解析：考查现在分词作宾语补足语。此处为“find+宾语+宾语补足语”结构,结合语境可知,当“我”走进办公室时,“我”发现很多人正在讨论这个项目。故这里表示发现某人正在做某事,应用现在分词作宾语补足语。
三、阅读理解
1. 答案：A
解析：细节理解题。根据第二段“What good does education do to you Research shows that education can lengthen your life expectancy! Getting more education leads to better employment, higher income, and access to healthcare. And all of these improve overall health. So, people with more education tend to have higher life expectancies than people with less education.(教育对你有什么好处 研究表明，教育可以延长你的预期寿命!接受更多的教育会带来更好的就业机会、更高的收入以及获得医疗保健的机会。而所有这些都能改善整体健康状况)”可知，教育可以是通向健康的一条途径。故选A项。

解析：词义猜测题。根据第三段最后一句“Of course, everyone still dies, but a lower mortality risk means a higher chance of a long life.(当然，每个人最终还是会死去，但较低的死亡风险意味着长寿的几率更高。)”可知，人人都会死去，但较低的“mortality”风险意味着长寿的机会更高，因此“mortality”应该是与死亡相关。故选B项。
3.答案：A
解析：主旨大意题。根据第四段“We reviewed previous studies that looked at education and mortality, searching seven databases of scientific studies from around the world. We gathered all the studies on this topic published between 1980 and 2023. In total, we identified 603 studies from 59 countries. We analyzed the results from all these studies to measure how education affected mortality risk. Besides, we also looked at differences in the effect of education at different ages. Finally, we checked the effect of education across Socio-Demographic Index levels.(我们回顾了以往关于教育与死亡率的研究，检索了来自全球的七个科学研究数据库。我们收集了1980年至2023年间发表的关于这个主题的所有研究。总共确定了来自59个国家的603项研究。我们分析了所有这些研究的结果，以衡量教育如何影响死亡风险。此外，我们还研究了不同年龄段教育影响的差异。最后，我们检查了不同社会人口指数水平下教育的影响。)”可知，该段主要讲述了研究人员回顾以前关于教育和死亡率的研究，分析这些研究结果以衡量教育对死亡风险的影响，还研究了教育在不同年龄的影响差异以及在不同社会人口指数水平下的影响，这些都是在阐述研究的方法和过程。故选A项。
4.答案：C
解析：推理判断题。根据最后一段“We found that getting more education lowers mortality risk. With each year of education, an adult’s risk of death goes down by about 2%. This effect is greater in younger adults than in older ones. But even people over 70 years old benefit from the positive effects of education! When we looked at countries at different stages of social and economic development, we didn’t find different results. This suggests that more years of schooling leads to longer lives in both rich and poor countries.(我们发现，接受更多的教育可以降低死亡风险。对于成年人来说，每接受一年的教育，死亡风险就会降低约2%。这种影响在年轻人中比在老年人中更大。但即使是70岁以上的人也能从教育的积极影响中受益!当我们观察处于不同社会和经济发展阶段的国家时，我们没有发现不同的结果。这表明，在富裕国家和贫穷国家，接受更多年的学校教育都能使人更长寿。)”可知，接受更多教育能降低死亡风险，每多接受一年教育，成年人的死亡风险下降约2%,这种影响在年轻人中比在老年人中更大，而且在不同社会经济发展阶段的国家都发现更多的受教育年限会带来更长的寿命，所以可以推断出教育确实会影响不同国家人们的寿命长短。故选C项。
四、七选五
答案：①-⑤GDFBE
解析：①上文“We live in a world where we are usually exposed to(接触)news on social media that can be scary, upsetting ,or confusing.(我们生活在这样一个世界里，我们经常在社交媒体上看到可怕的、令人不安的或令人困惑的新闻。)”提到，在这样一个世界里，我们经常在社交媒体上看到可怕的、令人不安的或令人困惑的新闻；再根据下文“However, as Mr. Rogers, the beloved host of a children’s show, once said, “When I was a boy and I would see scary things in the news, my mother would say to me, ‘Look for the helpers. You will always find people who are helpful.’ ”(然而，正如深受喜爱的儿童节目主持人Rogers先生曾经说过的那样，‘当我还是个孩子的时候，我经常在新闻中看到可怕的事情，我妈妈会对我说，‘去找帮手吧。你总能找到乐于助人的人。’')”可知，空处与下文是转折关系，应是提到对于负面新闻导致的情绪无法独自处理的情况，G项“有时候，处理这些事件引起的消极想法是很困难的”符合语境，故选G。
②上文“One of the places where we can look for‘the helpers’ is on social media platforms.(我们可以在社交媒体平台上寻找‘帮手’。)”提到我们可以在社交媒体平台上寻找“帮手”,D项“它们提供了很多可以教育或支持年轻观众的内容”承接上文，说明社交平台可以提供一些帮助，D项中的“They”指代上文的“social media platforms”,故选D。
③根据下文“One problem is finding reliable(可靠)and exact sources of information. Not all content on social media platforms is trustworthy.(一个问题是找到可靠的和准确的信息来源。并非社交媒体平台上的所有内容都值得信赖。)”可知，此处描述社交媒体平台的问题，与上一段之间是转折关系，F项“然而，在社交媒体上寻找帮手也面临着一些挑战”符合语境，故选F。
④上文“Spending too much time online can do harm to our physical health, such as causing headaches or sleep problems. Therefore, it is important to limit our screen time by doing other activities.(花太多时间上网会损害我们的身体健康，比如引起头痛或睡眠问题。因此，通过做其他活动来限制看屏幕的时间是很重要的。)”提到花太多时间上网会损害我们的身体健康，可以做一些其他活动代替，B项“锻炼、阅读和学习艺术都是不错的选择”承接上文，举例说明一些具体的活动，故选B。
⑤根据上文“Looking for helpers on social media can be a valuable way to find hope and comfort in difficulty.(在社交媒体上寻找帮手是在困难中找到希望和安慰的宝贵途径。)”和下文“Then we will form our own opinions.(然后我们会形成我们自己的观点。)”可知，此处是说明在社交媒体寻找帮手的好处，E项“它使我们能够从不同的角度看待事物并学习新事物”能够承上启下，符合语境，故选E。（3）Unit 3 Diverse Cultures—高一英语人教版（2019）必修第三册期末易错题集训

三、阅读理解
In a faraway part of Ecuador’s Amazon rainforest, river transport is far more common than road travel. Here, boats move along the Wichimi River, a wide channel that snakes through the thick plants, and powering the silent boats is the Ecuadorian sunshine. The boats have been provided by Kara Solar, a non-profit organization based in the region. The Achuar here are responsible for fixing, running and maintaining the boats — the solar boats are shaping daily life for the community by offering transport for education, health services and eco-tourism.
For years, many Achuar have used gasoline-powered boats on the river, but the oil must be flown in by plane from Ecuador’s capital, Quito, making it more expensive and adding to the carbon emissions (碳排放) connected with its use. “Gasoline motors use a lot of oil and pollute the river,” said Angel Wasump, Kara Solar’s director of operations and a member of the Achuar community. “Since the solar boats arrived, families have been giving up these motors completely,” he added.
Formally set up in 2018, Kara Solar is made up of by members of the Achuar community. According to the organization, the boats operating in Ecuador have completed over 300 trips in total, carrying over 1, 000 passengers and traveling over 450 kilometers per month. The most common uses are transporting local children to and from school and providing wildlife tours for eco-tourists.
As well as reducing carbon emissions and pollution, the silent boats mean eco-tourists can get a closer view of wildlife without scaring it away. “The boat serves as a symbol of what friendliness could look like,” said Wasump. “It’s like a return to what’s most important in Achuar culture. These boats have represented a way for us to reconnect with this vision of what development could look like.”
1. What can be inferred about the Achuar from paragraph 1
A. They live mostly by fishing. B. They lack ecology awareness.
C. They live in peace with snakes. D. They travel mainly by boat.
2. What is the advantage of a solar boat
A. It travels faster. B. It’s economical and green.
C. It’s easy to operate. D. It carries more passengers.
3. What does the author mainly intend to tell us about solar boats in paragraph 3
A. Their applications. B. Their operators.
C. Their bright future. D. Their characteristics.
4. What is the focus of Achuar culture according to Wasump
A. Keep their place quiet. B. Avoid lives being affected.
C. Live in harmony with nature. D. See the boat as a sign of faith.
四、七选五
Learning a new language is an exciting but challenging journey. There are several difficulties that language learners often face.
Complex Grammar
Different languages have their own unique grammatical rules. ① _____ For example, in English, the order of words in a sentence is important for expressing the correct meaning. However, in Japanese or Russian, the word order can be more flexible (灵活的). This difference can make it difficult for learners to form correct sentences and express themselves accurately (准确地).
Pronunciation Challenges
Each language has its own set of sounds. For example, the French “r” sound or the German “ü” sound can be extremely difficult for English speakers to pronounce correctly. What’s more, the stress of a language can also affect the meaning of a word or a sentence. ② _____
Limited Vocabulary
Building a large enough vocabulary is necessary for effective language learning. ③ _____ Some languages have a great number of words. Besides, many words may have several meanings or small differences that are difficult to understand. For example, in Chinese, a single character can have different meanings depending on the context.
Cultural Differences
④ _____ Idioms (习语), proverbs (谚语), and expressions in a language often show the culture and history of the people who speak it. For example, the English idiom “it’s raining cats and dogs” may not make sense to a learner who doesn’t know much about Western cultures.
Few Chances to Practice
Learners need regular chances to practise speaking, listening, reading, and writing. However, they may not be able to meet native speakers or stay in a language environment. ⑤ _____ For example, if a person is learning a language that is not widely spoken in their country, it may be challenging to find practice partners or language learning resources.
A. Language is closely related to culture.
B. It can be difficult to find chances to practise speaking.
C. Mistakes in pronunciation can lead to misunderstandings.
D. Learning a new language can be a worthwhile experience.
E. However, learning new words can be a slow and hard process.
F. This can make it difficult for them to improve their language skills.
G. They can be extremely different from those of a learner’s native language.
答案以及解析
二、语法填空
1.答案：listening
解析：考查时态，主谓一致和省略。句意:我边听边记笔记。
2.答案：destroyed
解析：考查状语从句的省略。句意：如果神经细胞被破坏，它们的恢复能力有限。分析句子可知，此处是if省略句，省略主语nerve cells和be动词，nerve cells和destroy之间是被动关系，因此需使用过去分词表示被动。故填destroyed。
3.答案：watching
解析：考查省略。句意：看这部纪录片的时候我很担心。当从句中的主语和主句中的主语一致时,可以省略从句中的主语和谓语。所以从句省略主语和谓语I was。根据句意,故填watching。
4.答案： giving
解析：考查状语从句的省略。句意：如果有人在流血，在进行急救护理时，请始终佩戴手套和防护眼镜。when引导的时间状语从句中，主语和主句主语一致，且含有be动词时，从句中主语和be可以省略。本句主句为祈使句，相当于主语是you，在when引导的时间状语从句中，根据语意，意思应为“当你在进行急救护理时”，完整句子应为when you are giving first aid care，故可把从句中you are省略。故填giving。
5.答案：looking
解析：句意为: 她在操场上走来走去, 好像在找什么东西。本句是复合句, 含 as if 引导的方式状语从句的省略, 从句主语和主句主语相同, 且从句谓语中含 be 动词, 所以可以省略从句中的主语和 be 动词。从句主语与 look 之间为主动关系,设空处应用现在分词形式。故填 looking。
6.答案： sown/sowed
解析：句意为:问题是种子在土壤中播种后多长时间能发芽。once后省略了they are,补充完整后为once they are sown/sowed in soil。故填sown/sowed。
7.答案：to say
解析：句意为:他清了清嗓子,像要说什么似的。as if引导的状语从句可用省略结构。当从句主语和主句主语一致且从句含有be的某种形式时,可省略从句的主语和be,此处省略了he was。故填 to say。
8.答案：handled
解析：考查省略。句意：如果处理不当，医院的医疗废物可能会导致疾病传播。这里其实是从句if medical waste is not handled properly的省略形式。当主、从句的主语一致的时候，可以省略从句的主语和be动词，被动语态省略了系动词和主语。故填handled。
9.答案：carved
解析：考查省略句。句意:中国有句古话:“玉不琢不成器。”此处为状语从句的省略，从句主语也是Jade，与谓语carve构成被动关系，此处省略主语和be动词。故填carved。
10.答案：hurt
解析：句意为: 足球运动员正在地上打滚, 好像腿受了重伤。状语从句中, 从句主语与主句主语一致, 且从句谓语含有 be 动词时, 从句中的 “主语+be 动词” 可以省略。此处完整从句为 as if he/she is hurt badly in the leg, 所以设空处应填 hurt。
三、阅读理解
1.答案：D
解析：细节理解题。根据文章第一段中“In a faraway part of Ecuador’s Amazon rainforest, river transport is far more common than road travel.(在厄瓜多尔亚马逊雨林的一个偏远地区，水路运输远比公路运输普遍)”可知，阿查乌族社区人民的生活很大程度上依赖于船。故选D项。
2.答案：B
解析：细节理解题。根据第二段中“For years, many Achuar have used gasoline-powered boats on the river, but the oil must be flown in by plane from Ecuador’s capital, Quito, making it more expensive and adding to the carbon emissions (碳排放) connected with its use.(多年来，许多阿丘阿尔人一直使用以汽油为动力的船只在这条河上航行，但石油必须从厄瓜多尔首都基多用飞机运来，这使得石油更加昂贵，并增加了与使用石油相关的碳排放)”可知，燃油船费用高，有污染。而太阳能船没有这些问题，即太阳能是经济且环保的。故选B项。
3.答案：A
解析：主旨大意题。根据第三段中“According to the organization, the boats operating in Ecuador have completed over 300 trips in total, carrying over 1, 000 passengers and traveling over 450 kilometers per month. The most common uses are transporting local children to and from school and providing wildlife tours for eco-tourists.(据该组织称，在厄瓜多尔作业的船只总共完成了300多次航行，载有1000多名乘客，每月航行450多公里。最常见的用途是接送当地儿童上下学，以及为生态游客提供野生动物之旅)”可知，本段主要介绍了太阳能船的应用。故选A项。
4.答案：C
解析：推理判断题。最后一段中“As well as reducing carbon emissions and pollution, the silent boats mean eco-tourists can get a closer view of wildlife without scaring it away. ‘The boat serves as a symbol of what eco-friendliness could look like,’ said Wasump.(除了减少碳排放和污染，安静的船只意味着生态游客可以更近距离地观察野生动物，而不会吓跑它们。‘这艘船是环保的象征，’Wasump说)”在提到游客乘坐无声船只近距离观察野生动物后，把这些太阳能船只称作生态友好的标志，然后归纳到：“It’s like are turn to what’s most important in Achuar culture.(这就像是回到了阿丘阿文化中最重要的东西)”，由此可推知，Wasump认为Achuar文化的核心是人与自然和谐相处。故选C项。
四、七选五
答案：GCEAF
解析：①根据上文“Different languages have their own unique grammatical rules. (不同的语言有自己的独特语法规则)”，可知这里说的是不同语言之间的语法差异。选项G“They can be extremely different from those of a learner’s native language. (它们可能与学习者的母语语法极为不同)”符合语境，故选G项。
②根据上文“What’s more, the stress of a language can also affect the meaning of a word or a sentence. (此外，语言的重音也会影响单词或句子的意思)”可知，这里讨论的是发音对语言理解的影响。选项C“Mistakes in pronunciation can lead to misunderstandings. (发音错误可能导致误解)”与上文内容紧密相连，故选C项。
③根据上文“Building a large enough vocabulary is necessary for effective language learning. (建立足够大的词汇量是有效语言学习的必要条件)”以及下文“Some languages have a great number of words. (有些语言有大量的单词)”可知，这里需要表达的是学习新单词的难度。选项E“However, learning new words can be a slow and hard process. (然而，学习新单词可能是一个缓慢而艰难的过程)”符合语境，故选E项。
④根据下文“Idioms (习语), proverbs (谚语), and expressions in a language often show the culture and history of the people who speak it. (语言中的习语、谚语和表达往往体现了说这种语言的人的文化和历史)”可知，这里讨论的是语言与文化之间的关系。选项A“Language is closely related to culture. (语言与文化密切相关)”与下文内容相呼应，故选A项。
⑤根据上文“However, they may not be able to meet native speakers or stay in a language environment. (然而，他们可能无法遇到母语使用者或待在语言环境中)”，可知这里需要表达的是缺乏练习机会对语言学习的影响。选项F“This can make it difficult for them to improve their language skills. (这使得他们很难提高语言技能)”与上文内容紧密相连，故选F项。（1）Unit 1 Festivals and Celebrations —高一英语人教版（2019）必修第三册期末易错题集训
一、易错点分析
动词-ing形式作定语和表语
动词-ing形式分为动名词和现在分词两类：
动名词兼有动词和名词的特征和作用，在句中作主语、宾语、表语和定语；
现在分词兼有动词、形容词和副词的特征，在句中作定语、表语、补足语和状语。
1. 动词-ing形式作定语
动名词和现在分词都可以作定语，但有所区别
(1)动名词作定语表示被修饰词的某种性能或用途，相当于名词+for +doing sth.
例：No one is allowed to speak aloud in the reading room (the room for reading).
谁都不准在阅览室里大声说话。
(2)现在分词作定语时，它和被修饰词之间有逻辑上的主动关系，表示所修饰词正在进行的动作相当于一个定语从句
例：The boy playing football on the playground is my younger brother.
=The boy that/who is playing football on the playground is my younger brother.
在操场上踢足球的那个男孩是我的弟弟。
(3)过去分词、现在分词以及不定式作定语时的区别
语法 形式 关系
过去分词作定语 done 表示被动、完成
现在分词作定语 doing 表示主动、动作正在进行
being done 表示被动、动作正在进行
不定式作定语 to do 表示主动、动作将要发生
to be done 表示被动、动作将要发生
2. 动词-ing形式作表语
作表语的动词-ing形式包括现在分词和动名词
(1)现在分词作表语，往往具有形容词的性质说明主语的性质、特征等
例：The argument is very convincing.
这个论断很令人信服。
He remained standing beside the table.
他依然站在桌旁。
(2)动名词作表语多说明主语的内容，表示笼统的、抽象的概念。主语和表语可以换位
例：Her job is teaching you English.
=Teaching you English is her job.
她的工作是教你们英语。
注意：
1. 动词-ing形式作定语和表语是高考语法中的重点，常常出现在阅读理解的长难句中，是语法填空的高频考点，也是打造书面表达中亮点句子的基础。
2. 许多现在分词是由能够表示人们某种感情或情绪的动词变化而来的。常见的有：
moving，interesting，encouraging，exciting，inspiring，boring surprising，puzzling，amusing，astonishing等。这类分词有"令人……的"的含义，常修饰物，可在句中作表语或定语。
例：The director was fully convinced that this moving story, if adapted for television, would be a hit.
导演完全相信，这个感人的故事如果被改编成电视剧，将会大受欢迎。
We all have the opinion that the basketball match was encouraging.
我们都有这个看法，就是这场篮球比赛很鼓舞人心。
3. 不定式和过去分词也可作表语，但不定式通常强调一次性的、具体的、将要发生的动作，过去分词则表示被动、完成的含义。
例：Her hobby is painting.
她的爱好是画画。(抽象的、习惯性的动作)
His wish is to become an artist.
他的愿望是成为一名艺术家。(将要发生的动作)
The cup was broken.
茶杯被打碎了。(被动、已完成的动作)

三、阅读理解
When your pen is broken, the batteries (电池) in your toys run out, or you have some leftover food, what will you do with these things You will probably throw them all into one bin. But actually, all of these pieces of rubbish need to be sorted (分类) separately.
Rubbish sorting is a big problem worldwide. In recent years, some Chinese cities have been working hard on it. Shanghai has worked with Alipay to create a “green account (账户)” service. Account owners get points by correctly sorting their rubbish. Through the Alipay app, they can exchange the points for milk, phone cards or other products. The city is asking all people living there to sort their rubbish into four groups: wet, recyclable, harmful and dry.
Wet waste is something you don’t want but that pigs can eat. Plastics, glass, paper and other things that can be reused are recyclable waste. Harmful waste includes things like medicine, batteries and bulbs. Finally, any waste that’s not wet, recyclable or harmful will go in the “dry waste” bin.
Many other Chinese cities are also sorting their rubbish in this way. For example, Shenzhen has been doing this since 2012. Students there also receive waste-sorting guidebooks that they must study. In fact, there are still many workers specially working for sorting rubbish by hand in China. There is still a long way to go. But it’s never too late for every Chinese to learn how to sort rubbish properly and protect the environment.
If you don’t sort your rubbish, all of it will go to a landfill (垃圾填埋场) and be buried together. These landfills can take up much ground that could be used for planting. The electronic waste you throw away, such as batteries or used mobile phones, can cause pollution. Other pieces of rubbish, like the metal part of a pen, can be used to make other things if they are properly recycled.
1. Shanghai creates the “green account” service in order to ______.
A. work with the Alipay app. B. punish those who don’t sort rubbish.
C. exchange useful products. D. encourage people to sort their rubbish.
2. After drinking up the milk, you can put the milk box into a “______ waste” bin.
A. wet. B. recyclable. C. harmful. D. dry.
3. The last paragraph is mainly about ______.
A. why we should sort rubbish properly. B. where our rubbish can be dealt with.
C. how some waste can be recycled. D. what waste can cause pollution.
4. Which is NOT TRUE about rubbish sorting in China according to this passage
A. There is still a long way to go in rubbish sorting.
B. There are many workers sorting rubbish by hand.
C. Students have to take waste-sorting classes in school.
D. Shenzhen has been doing rubbish sorting for a decade roughly.

答案以及解析

三、阅读理解
Migratory birds (候鸟) rely on a network of habitats across continents (洲). Today, scientists with the National Audubon Society published a study in which they propose a new way to identify where conservation efforts are most needed to ensure the survival for migratory birds that travel between Canada and South America.
The study integrates movement data from more than 329,000 birds of 112 species to identify the areas where migratory birds face the greatest threats from climate change and habitat loss. Researchers introduce a new way called multispecies migratory connectivity to measure these threats. Despite a growing understanding of how birds connect across different places and seasons, by combining connectivity patterns across many species with future climate changes and habitat changes, researchers find out the migration paths at the highest risk throughout the Americas.
The findings show that migration paths between some breeding (繁殖) regions in Canada and non-breeding regions in South America are particularly vulnerable, suggesting the threats faced by long-distance migrants. Alarmingly, over half of the migration paths at very high risk involve breeding regions in the eastern United States. “Bird migration is one of the most incredible and impressive phenomena in nature. This new science highlights the need for continued investment and international efforts to reduce the dangers migratory birds meet across the entire continents,” said Dr. Jill Deppe, senior director of Audubon’s Migratory Bird Initiative.
A 2019 study determined that there are nearly three billion fewer birds in North America than in the year 1970, with two-and-a-half billion of those birds considered migratory birds. The survival of many of these migratory species remains uncertain if countries do not take action to reduce climate pollution and the impacts of human activities that threaten birds and their habitats. By learning more about the threats these birds are facing during their annual cycle, we can focus on the places and actions that will have the biggest impact for securing their future.
1. What is multispecies migratory connectivity used to do
A. Track the migration paths of many species.
B. Identify suitable habitats for breeding birds.
C. Measure the risks faced by migratory birds.
D. Guess future populations of migratory birds.
2. What does the underlined word “vulnerable” in paragraph 3 mean
A. Easily damaged. B. Equally improved.
C. Well protected. D. Widely spread.
3. Why is the 2019 study mentioned in the last paragraph
A. To praise the success of conservation efforts.
B. To stress the necessity of conservation action.
C. To compare migration patterns of different bird species.
D. To explain the causes of climate change affecting birds.
4. What can be the best title for the text
A. The Role of Global Efforts in Bird Conservation
B. New Scientific Tools for Tracking Bird Migration
C. How Climate Change Is Reshaping Bird Migration Pattern
D. Scientists Identify Key Areas for Protecting Migratory Birds
四、七选五
Here we’ve got three tips to help you start an exercise habit that can stick. It’s a lot easier than you think.
①_________
You don’t have to be a marathoner to get meaningful health benefits from exercise. Experts say even daily activities, which include mopping the floor, organizing a room or carrying groceries up the stairs can reduce the risk of diseases like diabetes, heart disease and even some cancers.
So remind yourself that it’s not a choice between hours-long workout or nothing at all. Instead, think of starting an exercise routine like standing up from your chair and sitting back down repeatedly. ②_________
Focus on how exercise makes you feel great
There are so many positives that happen when you move. It improves all the tasks that demand focus and creativity. It helps you generate energy. It boosts mood. ③_________. When you feel better, you will bring more enthusiasm and energy to your work and the people working around you.
Forget long- term benefits like weight loss or better overall health. ④_________. Actually, they’re not super motivational in real-time and can be disheartening when you don’t see results quickly.
Figure out what kind of exercise and workout location makes you feel good
If weightlifting in a crowded gym gives you anxiety, try to get a set of weights for home or follow workout videos on YouTube or ride a bike in the park. ⑤_________.
A. Start small and every movement counts
B. They often take much longer time to achieve
C. Focus on immediate payoffs like improved mood and energy
D. In short, any movement helps to clear fat and sugar out of the blood
E. Remember, when you have more energy, you’re a happier person
F. Keep trying until you find a workout routine that makes you happy
G. No matter how modest those goals are, they create this feeling like I can do more
答案以及解析
二、语法填空
1.答案：may/might
解析：考查情态动词。句意：她的外貌变化太大了,你很可能认不出她来。may/might well“很可能”,固定短语,故填may/might。
2.答案：would
解析：考查情态动词。句意：据说那位老太太总会坐在大树下,等着儿子从前线回来。结合句意可知,此处表示过去反复进行的动作,应用情态动词would。故填would。
3.答案：must
解析：考查情态动词。句意：读了四个小时的书,你一定累了。此处表示肯定推测,意为“肯定”应用must,故填must。
4.答案：should
解析：考查情态动词。句意：阅读英文小说大大增加了我的词汇量——我建议你也试一试。suggest表示“建议”,后面的宾语从句使用虚拟语气,从句谓语部分使用“should+动词原形”,故填should。
5.答案：needn't
解析：考查情态动词。由now that后“Suzie不和我们一起吃晚饭”可知,空处表示的是“(我们)本来没必要买如此多的食物”。needn't have done sth表示“本没必要做某事,而实际上做了”。
6.答案：must
解析：句意:——你不能再待时间长一点吗 ——时候不早了,我现在必须得走了。我女儿自己在家呢。本句中must意为“必须”。
7.答案：Would
解析：句意:你介意我为了一些问题麻烦你吗 would在此处表示委婉的请求。
8.答案：may/might
解析：考查情态动词。句意:既然交通如此拥挤，我们还是乘地铁去吧。此处是固定搭配:may as well或者might as well意为“只好(做);(做……)也无妨”。故填may或者might。
9.答案：could
解析：考查情态动词。句意:餐厅里太吵了，我们都听不见自己说话，所以我们到外面聊天。设空处填写情态动词与后文的not hear构成情态动词的否定结构。根据前文的was可知，句子表述过去事实，故使用一般过去时。表示“能够”用can，其过去式是could。故填could。
10.答案：needn’t
解析：考查情态动词。句意：你现在不必还书；如果你愿意，你可以把它保留到下周。此处表示“不必”应用needn't。故填needn't。
三、阅读理解
1.答案：C
解析：细节理解题。根据第二段中“The study integrates movement data from more than 329,000 birds of 112 species to identify the areas where migratory birds face the greatest threats from climate change and habitat loss. Researchers introduce a new way called multispecies migratory connectivity to measure these threats. (该研究整合了112个物种的329,000多只鸟类的迁徙数据，以识别候鸟面临气候变化和栖息地丧失最大威胁的区域。研究人员引入了一种名为“多物种迁徙连通性”的新方法来衡量这些威胁。)”可知，多物种迁徙连通性是用来衡量候鸟面临的风险的。故选C。
2.答案：A
解析：词句猜测题。根据第三段中划线词下文“suggesting the threats faced by long-distance migrants (表明长途迁徙者面临的威胁)”和“Alarmingly, over half of the migration paths at very high risk involve breeding regions in the eastern United States. (令人担忧的是，超过一半的高风险迁徙路线涉及美国东部的繁殖区。)”可知，研究结果表明，加拿大一些繁殖区与南美洲非繁殖区之间的迁徙路线尤其脆弱，vulnerable意为“脆弱的，易受伤的”，和Easily damaged意思相近。故选A。
3.答案：B
解析：推理判断题。根据最后一段中“A 2019 study determined that there are nearly three billion fewer birds in North America than in the year 1970, with two-and-a-half billion of those birds considered migratory birds. The survival of many of these migratory species remains uncertain if countries do not take action to reduce climate pollution and the impacts of human activities that threaten birds and their habitats. (2019年的一项研究确定，北美地区的鸟类数量比1970年减少了近30亿只，其中25亿只是候鸟。如果这些国家不采取行动减少气候污染和人类活动对鸟类及其栖息地的威胁，许多迁徙物种的生存仍然不确定。)”可推知，最后一段提到了2019年的研究是为了强调保护行动的必要性。故选B。
4.答案：D
解析：主旨大意题。通读全文，尤其是第一段中“Today, scientists with the National Audubon Society published a study in which they propose a new way to identify where conservation efforts are most needed to ensure the survival for migratory birds that travel between Canada and South America. (如今，美国奥杜邦协会的科学家们发表了一项研究。在这项研究中，他们提出了一种新方法，用以确定在哪些地方最需要开展保护工作，从而确保在加拿大和南美洲之间迁徙的候鸟能够生存下来。)”可知，本文主要讲的是美国奥杜邦协会的科学家们发表了一项研究，提出了一种新方法来确定在加拿大和南美洲之间迁徙的候鸟最需要保护的地方，因此D选项“Scientists Identify Key Areas for Protecting Migratory Birds(科学家确定了保护候鸟的关键区域)”很好地概括文章主旨，是文章的最佳标题。故选D。
四、七选五
答案：①-⑤ADEBF
解析：①根据后文“You don’t have to be a marathoner to get meaningful health benefits from exercise. Experts say even daily activities, which include mopping the floor, organizing a room or carrying groceries up the stairs can reduce the risk of diseases like diabetes, heart disease and even some cancers.(你不必成为一名马拉松运动员才能从锻炼中获得有意义的健康益处。专家说，即使是日常活动，包括拖地、整理房间或把杂货搬上楼梯，也可以降低患糖尿病、心脏病甚至某些癌症等疾病的风险)”可知，本节主要是讲锻炼身体不需要每天坚持跑马拉松。日常家务，甚至经常从椅子上站起来走走都能达到锻炼的目的。故A选项“从小处入手，每个活动都重要”符合语境，故选A。
②根据上文“You don’t have to be a marathoner to get meaningful health benefits from exercise.(你不必成为一名马拉松运动员才能从锻炼中获得有意义的健康益处)”以及“So remind yourself that it’s not a choice between hours-long workout or nothing at all. Instead, think of starting an exercise routine like standing up from your chair and sitting back down repeatedly.(所以提醒自己，这不是在长时间锻炼和什么都不做之间的选择。相反，可以考虑开始锻炼，比如从椅子上站起来，然后反复坐下来)”可知，本段主要说的是小活动也可以锻炼身体，本句为本段最后一句，进行总结。故D选项“总之，每一个活动都有利于清除血液中的脂肪和能量”符合语境，故选D。
③根据上文“There are so many positives that happen when you move. It improves all the tasks that demand focus and creativity. It helps you generate energy. It boosts mood.(当你行动的时候，会有很多积极的事情发生。它可以改善所有需要专注力和创造力的任务。它能帮助你产生能量。它能提高心情)”以及后文“When you feel better, you will bring more enthusiasm and energy to your work and the people working around you.(当你感觉更好的时候，你会给你的工作和你周围的人带来更多的热情和能量)”可知，上文提到锻炼不但能提气还能提神，空后又提到这种精神气还能感染你周围的人，故本句承上启下，说明精力充沛的好处。故E选项“记住，你精力充沛时会感到更幸福”符合语境，故选E。
④根据上文“Forget long- term benefits like weight loss or better overall health.(忘记长期的好处，如减肥或更好的整体健康)”可知，上文提到忘记长期的好处，本句说明原因：它们需要很长时间才能见效。故B选项“它们需要很长时间才能见效”符合语境，故选B。
⑤根据上文“If weightlifting in a crowded gym gives you anxiety, try to get a set of weights for home or follow workout videos on YouTube or ride a bike in the park.(如果在拥挤的健身房举重让你感到焦虑，那就试着在家里买一套举重器材，或者关注YouTube上的锻炼视频，或者在公园里骑自行车)”可知，上文说明了要不断尝试各种活动，本句为本段最后一句，应承接上文说明原因：不停地尝试直到找到能让自己满意的活动。故F选项“不停地尝试直到找到能让自己满意的活动”符合语境，故选F。
