A
(2019年高考·北京卷)
By the end of the century，if not sooner，the world's oceans will be bluer and greener thanks to a warming climate，according to a new study.
At the heart of the phenomenon lie tiny marine microorganisms(海洋微生物)called phytoplankton.Because of the way light reflects off the organisms，these phytoplankton create colourful patterns at the ocean surface.Ocean colour varies from green to blue，depending on the type and concentration of phytoplankton.Climate change will fuel the growth of phytoplankton in some areas，while reducing it in other spots，leading to changes in the ocean's appearance.
Phytoplankton live at the ocean surface，where they pull carbon dioxide(二氧化碳)into the ocean while giving off oxygen.When these organisms die，they bury carbon in the deep ocean，an important process that helps to regulate the global climate.But phytoplankton are vulnerable to the ocean's warming trend.Warming changes key characteristics of the ocean and can affect phytoplankton growth，since they need not only sunlight and carbon dioxide to grow，but also nutrients.
Stephanie Dutkiewicz，a scientist in MIT's Center for Global Change Science，built a climate model that projects changes to the oceans throughout the century.In a world that warms up by 3℃，it found that multiple changes to the colour of the oceans would occur.The model projects that currently blue areas with little phytoplankton could become even bluer.But in some waters，such as those of the Arctic，a warming will make conditions riper for phytoplankton，and these areas will turn greener.“Not only are the quantities of phytoplankton in the ocean changing.”she said，“but the type of phytoplankton is changing.”
And why does that matter？Phytoplankton are the base of the food web.If certain kinds begin to disappear from the ocean，Dutkiewicz said，“it will change the type of fish that will be able to survive.”Those kinds of changes could affect the food chain.
Whatever colour changes the ocean experiences in the coming decades will probably be too gradual and unnoticeable，but they could mean significant changes.“It'll be a while before we can statistically show that the changes are happening because of climate change，”Dutkiewicz said，“but the change in the colour of the ocean will be one of the early warning signals that we really have changed our planet.”
1．What are the first two paragraphs mainly about?
A．The various patterns at the ocean surface.
B．The cause of the changes in ocean colour.
C．The way light reflects off marine organisms.
D．The efforts to fuel the growth of phytoplankton.
2．What does the underlined word“vulnerable”in Paragraph 3 probably mean?
A．Sensitive. B．Beneficial.
C．Significant. D．Unnoticeable.
3．What can we learn from the passage?
A．Phytoplankton play a declining role in the marine ecosystem.
B．Dutkiewicz's model aims to project phytoplankton changes.
C．Phytoplankton have been used to control global climate.
D．Oceans with more phytoplankton may appear greener.
4．What is the main purpose of the passage?
A．To assess the consequences of ocean colour changes.
B．To analyse the composition of the ocean food chain.
C．To explain the effects of climate change on oceans.
D．To introduce a new method to study phytoplankton.
答案与解析
本文为说明文。一项最新研究表明，由于气候变暖，世界海洋将会变得更蓝、更绿。这一现象是因为一种叫作浮游植物的微小海洋微生物，因为光线反射的作用，它们在海洋表面形成了五颜六色的图案。但是浮游植物很容易受到海洋变暖趋势的影响，气候变暖会改变海洋的主要特征，并影响浮游植物的生长。
1．B 段落大意题。第一段“By the end of the century.If not sooner, the world's oceans will be bluer and greener thanks to a warming climate, according to a new study.”可知，到本世纪末，一项新的研究表明，由于气候变暖，如果不尽快的话，世界上的海洋将会变得更蓝、更绿。结合第二段中的“At the heart of the phenomenon lie tiny marine microorganisms(海洋微生物)called phytoplankton.Because of the way light reflects off the organisms，these phytoplankton create colourful patterns at the ocean surface.Ocean colour varies from green to blue, depending on the type and concentration”可知，这种现象的核心是一种叫作浮游植物的微小海洋微生物，在光线的作用下在海洋表面形成了五颜六色的图案。海洋的颜色从绿色到蓝色不等，这取决于海洋的类型和浮游植物浓度。由此可推断出这两段主要叙述了海洋生物是海洋颜色变化的原因。分析选项可知B符合题意，故选B。
2．A 词义猜测题。根据划线词后的“Warming changes key characteristics of the ocean and can affect phytoplankton growth, since they need not only sunshine and carbon dioxide to grow, but also nutrients.”可知，气候变暖会改变海洋的主要特征，并会影响浮游植物的生长。由此可判断“But phytoplankton are vulnerable to the ocean's warming trend”可知，浮游植物很容易受到海洋变暖趋势的影响。可知A项正确。
3．D 推理判断题。根据第四段中的“The model projects that currently blue areas with little phytoplankton could become even bluer.But in some waters，such as those of the Arctic, a warming will make conditions riper for phytoplankton, and these areas will turn greener”，可知“Dutkiewicz的模型预测，目前只有少量浮游植物的蓝色区域可能会变得更蓝。但是在一些水域，比如北极，气候变暖会使浮游植物的生长条件更加成熟，而这些水域会变得更绿了”。由此可推断，浮游植物的生长条件更加成熟，浮游动植物就更多了，这些水域会变得更绿了。分析选项可知D项符合题意。
4．C 主旨大意题。第一段提出文章的主旨“By the end of the century，if not sooner, the world's oceans will be bluer and greener thanks to a warming climate, according to a new study.”可知到本世纪末。一项新的研究表明，由于气候变暖，如果不尽快的话，世界上的海洋将会变得更蓝、更绿。再结合第三段中“But phytoplankton are vulnerable to the ocean's warming trend.Warming changes key characteristics of the ocean and can affect phytoplankton growth，...”可知，“浮游植物很容易受到海洋变暖趋势的影响，变暖改变了海洋的关键特征，并能影响浮游植物的生长”。可知本文主要解释气候变化对海洋及其植物的影响。故选C。
B
How did the sea horse get its name? It's not hard to guess.The top half of this fish looks like a small horse.But looking at the sea horse's tail, you might think “sea monkey”is a better name.Then there's the sea horse's pouch (袋)．“Sea kangaroo” might also be a good name for this fish.
Sea horses live in warm ocean waters all over the world.They keep safe from other fish by hiding in plants and grasses that grow under the sea.They can also change colors to match their surroundings (环境)．A sea horse remains in one place for hours at a time by winding (缠绕) its tail around a plant.It feeds on live food, such as small shrimp.For a fish that doesn't move around much, the sea horse eats a lot—in just one day, a sea horse can eat 3，000 shrimp!
A sea horse keeps the same mate for its whole life, and it's the male (雄的) sea horse that gives birth to baby sea horses.How does this happen? Baby sea horses start out as eggs, which come from the female's body.The male carries the eggs in its pouch for about three weeks until they hatch (孵化)．Soon after the babies are born, the female gives her mate a new set of eggs.The male sea horse spends most of its life carrying eggs.
Sadly, the number of sea horses is becoming smaller.Why is this happening? Some places where sea horses once lived have been filled in to make new land.Also, many sea horses are caught and sold as aquarium fish.This really is not a good idea because most sea horses don't live long in aquariums.The best place for a sea horse is the ocean.
5．How does a sea horse keep safe from other fish?
A．It hides in plants and grasses.
B．It runs away quickly.
C．It remains still.
D．It rolls up.
6．What does a female sea horse do with her eggs?
A．She puts them in the male's pouch.
B．She hides them in sea grasses.
C．She carries them around.
D．She hatches them.
7．Why is the number of sea horses becoming smaller?
A．They grow at a very low speed.
B．Their homes are being destroyed.
C．They are killed by people for food.
D．Their food is becoming less and less.

In summer the extreme heat often makes people sweaty and restless.While people are annoyed by it, experts suggest summer is the best season to discharge (排放) your body's toxins (毒素) and recover your energy.
One popular option is hot-stone massage (按摩)．Therapists use smooth and heated stones, usually river rocks, to massage certain parts of the body, or place them on key points of the body.The warmth of the hot stones will improve blood circulation and also help relax muscles, while sweating is also believed to be good for discharging the body's toxins.
Another popular option is hot-stone baths.The hot-stone bath will help the body discharge toxins and humidity that accumulated during the last winter.Summer is the best season to build a good body.Rather than use water or steam to heat and wash the body, people simply wear a coat or something comfortable, and then lie on heated stone tablets made of hot stones, which are warmed to around 45℃.The body will gradually warm up and blood circulation will also be improved.More sweat will come out quickly.The sweat is smooth and fresh, not smelly like that released after sports activities.Such baths bring a number of health benefits, such as anti-aging, improved blood circulation and stress relief.The slimming effect of dieting can even be promoted.
Using hot stones for healing dates back to ancient times, but the modern renewal of hot-stone massage is generally credited to Mary Nelson, a native of Tucson, Arizona, America, whose trademark is “LaStone Therapy”．
The therapy is gaining wide popularity with many people, especially those who have jobs in cool air-conditioned rooms.The hot-stone therapy can help cure many diseases, including back pain.
8．What do people use to release toxins in our body according to the text?
A．Washing the body with cold water.
B．Discharging lots of sweat.
C．Relaxing muscles.
D．Lying on the warm beds.
9．What can we know from the text?
A．Sports have greater effects on the health than hot-stone massage.
B．There are no toxins and humidity in the body in summer.
C．Using water of about 45 ℃ to wash the body is good for the health.
D．People should take advantage of summer to improve their health.
10．What can be learned about the hot-stone therapy?
A．It was invented by Mary Nelson, an American.
B．It successfully cured many people of cancer.
C．It is popular with people with its excellent effects.
D．It can help people avoid sweating too much in hot summer.
11．Which of the following could be the best title for the text?
A．The origin and development of the hot-stone therapy
B．The amazing functions of the hot-stone therapy
C．A healthy and comfortable lifestyle
D．How to live comfortably in summer

Plastic sludge(污泥)and garbage is a disaster for the world's oceans.A film crew traveled the globe to document the rubbish.And Julie Andersen of the Plastic Oceans Foundation says what we see is just the tip of the problem.“Half of the waste actually sinks to the bottom，and that that remains on the surface actually breaks down.”
The filmmakers found rubbish in ocean gyres(环流)，the circulating currents that trap large concentrations of pollution in the Atlantic，Indian，and Pacific Oceans，home of what some have plastic.“What we found was a plastic smog that spread throughout all the water.And in some parts of the oceans，scientists have found more plastic than plant.”
The pieces of the plastic garbage infect the food chain，sometimes visibly, and more so at the microscopic level，where the plastic particles interact with other pollutants.“There are heavy metals, medicines，industrial waste in the sea，while it acts like magnets(磁铁)．These poisonous substances absorb on the plastic，and then when seafood absorbs the plastics，those poisonous substances enter the fattytissues.”To be consumed by other sea life and by people at last.
China，Indonesia，the Philippines，Thailand and Vietnam are the worst plastic polluters.The United States，although a leader in recycling，is one of the world's 20 since it produces and consumes so much plastic.There are efforts around the world to address the problem，including at this newly opened recycling center in Lebanon(黎巴嫩)．But Andersen says there is more that people can do.“Cut back on single－use plastics，straws，plastic cups，plastic water bottles，plastic bags and find alternatives like reusable materials.”She says healthy oceans are essential to our survival.
1．What can we learn from the passage?
A．There's all island full of plastic rubbish in the Pacific.
B．The bad effect of plastic pollution can't be seen by eyes.
C．The United States is the least plastic polluters.
D．The plastic pollution to oceans is more serious than what we can see.
2．What does the underlined word “it” refer to in Paragraph 3?
A．Pollutants like heavy metals and medicines.
B．The plastic particles.
C．Seafood.
D．Fatty tissues.
3．What can be inferred from the last paragraph?
A．All Asian countries have the most serious problem of plastic pollution.
B．The plastic problem hasn't attracted the world's attention.
C．Andersen is not satisfied with what has been done to solve the plastic problem.
D．People should stop using plastic products immediately.
4．Which may be the title of the passage?
A．Plastic pollution in the World
B．Plastic pollution—Oceans'Disaster
C．Ways to solve the problem of plastic pollution to oceans
D．Plastic pollution and our health
答案与解析
这是一篇说明文。主要讲述了塑料污染对海洋导致的影响。
1．D 细节理解题。根据第一段第三句：And Julie Andersen of the Plastic Oceans Foundation says what we see is just the tip of the problem.可知，塑料对海洋的污染比我们所看到的更严重，故选D。
2．B 词义猜测题。根据The pieces of the plastic garbage infect the food chain，sometimes visibly，and more so at the microscopic level，where the plastic particles interact with other pollutants.“There are heavy metals，medicines，industrial waste in the sea，while it acts like magnets(磁铁)．”可知，塑料垃圾碎片在微观层面感染食物链，有时是明显的，塑料颗粒与其他污染物相互作用。海洋中有重金属，药物，工业废物，使其像磁铁一样，it指代的是塑料颗粒。故选B。
3．C 推理判断题。根据But Andersen says there is more that people can do.“Cut back on single－use plastics，straws，plastic cups，plastic water bottles，plastic bags and find alternatives like reusable materials.”She says healthy oceans are essential to our survival.可知，安德森对于解决塑料问题所做的工作不满意。故选C。
4．B 主旨大意题。阅读全文，根据文章内容可知，本文主要讲述了塑料污染——海洋灾难。故选B。
B
Regardless of how far we'd like to believe gender(性别)equality in the workplace has come, there's still a yawning gap between male and female leaders in the professional world.A 2018 statistic shows that women nowadays hold just 5.8 percent of CEOs positions at S&P 500 companies, according to Catalyst.
While it's not a huge shock that women are somewhat underrepresented in leadership positions, what is surprising though, is the fact that females may actually be better suited to lead in almost every area, at least according to new findings from the BI Norwegian Business School.
In their research, Professor Oyvind L．Martinsen and Professor Lars Glas surveyed (调查) 2，900 managers with a special focus on personality types.The results were clear: Women scored higher than men in four of the five major leadership-centric categories.
While some people believe that men inherently make better leaders—probably because they picture a leader with a commanding voice, which is more typical of men than women—this piece of research suggests that women are better at methodical management and goal-setting, openness, sociability and supportiveness, as well as ability to communicate clearly.
There was one area in which men scored higher than women, though, and that was on emotional stability and ability to face job-related pressure and stress.The results suggest that women are more sensitive to the effects of high-pressure or highly emotional situations.
Obviously, it's important to consider individual (个人的) differences.Anyone, regardless of gender, may be an inspiring leader and a competent boss.But next time you're hiring for a management position, you just might want to give the resumes (简历) from female candidates a harder look.
5．What makes us shocked much at leadership positions?
A．Women are worse than men.
B．Men take almost all high positions.
C．There is a huge gap between genders.
D．Women might behave better in nearly every field.
6．Which of the following can best replace the underlined word “inherently” in Paragraph 4?
A．properly. B．potentially.
C．naturally. D．normally.
7．Which of the following may be the best title of this text?
A．How We Can Figure Out the Boss
B．Why Women Are Better Than Men
C．Why Women Make the Best Bosses
D．How We Can Tell Gender Difference
8．Who might have special interest in this article?
A．Job hunters. B．Employers.
C．Employees. D．Male bosses.
答案与解析
这是一篇议论文。本文讲述了在工作领域男性领导人和女性领导人地位不平等现象，指出一个研究结果显示，在领导位置上，女性可能在各个领域表现更好，倡议雇主在招聘领导岗位员工时应多考虑女性。
5．D 根据第二段中的“what is surprising though，is the fact that females may actually be better suited to lead in almost every area，at least according to new findings from the BI Norwegian Business School.”得知，让人惊讶的是，在领导位置上，女性可能在各个领域表现更好。故选D。
6．C 词义猜测题。根据第四段中的“While some people believe that men inherently make better leaders — probably because they picture a leader with a commanding voice, which is more typical of men than women”得知，人们认为男性自然能成为更好的领导者，画线词意思是“自然地”。故选C。
7．C 标题归纳题。文章主要围绕一个研究结果来展开论述，根据第四段中的“this piece of research suggests that women are better at methodical management and goal-setting, openness, sociability and supportiveness, as well as ability to communicate clearly.”得知，本文强调了女性在管理层的地位，因此“为什么女性是最好的老板”这个标题切题。故选C。
8．B 推理判断题。根据文章最后一句“But next time you're hiring for a management position, you just might want to give the resumes(简历) from female candidates a harder look.(但下次你要招聘一个管理职位时，你可能只想更认真地从女性候选人的简历中找出一份。)”得知，雇主们会对这篇文章感兴趣。故选B。
C
That little “a” with a circle around it that is found in e-mail addresses is most commonly referred to as the “at” symbol. Surprisingly though, there is no official, universal name for this sign. There are lots of strange terms to describe the @ symbol.
Before it became the fixed symbol for e－mail, the symbol was mostly used to represent the cost or weight of something. For instance, if you bought 6 apples, you might write it as 6 apples @ $1.11 each.
With the introduction of e-mail came the popularity of the @ symbol. The @ symbol separates a person's online user name from his mail server address, for instance joe@uselessknowledge.com. Its widespread use on the Internet made it necessary to put this symbol on keyboards in countries that had never seen or used the symbol before. As a result, there is really no official name for this symbol.
The actual origin of the @ symbol remains unknown. History tells us that the @ symbol came from the tired hands of the monks(僧侣) in the Middle Ages. During the Middle Ages when there were no printing presses, every letter of a word had to be copied by hand for each copy of a published book. The monks that performed these long and boring copying duties looked for ways to reduce the number of strokes(笔画) per word for common words.
Although the word “at” is quite short, it was such a common word in texts and documents that monks in the Middle Ages thought it would be good idea to shorten the word “at” even more. As a result, the monks left out the “t” and created a circle-getting rid of two strokes.
9．Before becoming a symbol for e-mail, the @ symbol was most commonly used__________．
A．when people referred to the cost or weight of something
B. to represent the word “at” in computer languages
C. to represent the word “at” on keyboards
D. when people wrote business documents
10．Why did the @ symbol become popular?
A. Because it looked interesting.
B. Because e-mail appeared.
C. Because it was used by monks.
D. Because it was officially used in texts.
11．We can know from the passage that in the Middle Ages__________．
A．monks were hard-working
B．the printing press was invented
C．the @ symbol was seldom seen in texts
D．the work of copying books needed to be done all by hand
12．Monks in the Middle Ages replaced the word “at” with the @ symbol mainly to__________．
A．make the word look better
B．save their effort and time
C．keep some information secret
D．make it easier to understand
答案与解析
本文是一篇说明文，介绍了@这一符号的历史和发展。
9．A 细节理解题。根据第二段中的“Before it became the fixed symbol for e－mail, the symbol was mostly used to represent the cost or weight of something.”可知，在成为电子邮件的固定符号之前，@这个符号主要用来表示某物的价格或重量，故A项正确。
10．B 细节理解题。根据第三段中的“With the introduction of e－mail came the popularity of the @ symbol.”可知，随着电子邮件的使用，@这一符号越来越普及了，故B项正确。
11．D 细节理解题。根据第四段中的“During the Middle Ages when there were no printing presses, every letter of a word had to be copied by hand for each copy of a published book.”可知，中世纪没有印刷机，抄书的工作需要靠手工完成，故D项正确。
12．B 推理判断题。根据第四段中的“History tells us that the @ symbol came from the tired hands of the monks(僧侣) in the Middle Ages.”可知，历史告诉我们，@这一符号源自中世纪僧侣疲劳的双手，以及后文中，僧侣们手工抄书，疲惫乏味，为减少工作量，将“at”写作@，即是为了节省时间和精力，故B项正确。

We are aiming to build a peaceful school.I thought it is every student's duty to work hard to achieve this goal.As high school student, what should we do? First for all, we should love our school.Meanwhile, you should respect our teachers and obeying the rules in our school.Secondly, we should show our respect for our parents and do which we can help them.Besides, we classmates should also try to be kind and friendly.Most important, all of us must believe in each other and been honest in our daily life.And we will study even more harder and try our best to do all.
答案与解析
1．thought→think 考查动词。本句说的是现在的事情，所以要用一般现在时态，故thought改为think。
2．student→students 考查名词。名词student是可数名词，指我们，所以要用复数形式，故student改为students。
3．for→of 考查介词。固定短语：first of all(首先)，故for改为of。
4．you→we 考查代词。此处是说我们要尊重我们的老师并且遵守学校的规则，人称用错，故you改为we。
5．obeying→obey 考查动词。根据句子结构，respect和obey是并列的谓语动词，故obeying改为obey。
6．which→what 考查代词。在do what we can (do) to help them.的句中，要用连接代词what引导宾语从句，作do(此处do省略了)的宾语，故which改为what。
7．help前面加to 考查不定式。在do what we can (do) to help them的句中，不定式to help them作目的状语，故help前面加to。
8．important→importantly 考查副词。副词短语most importantly(非常重要的是)在句中作状语，故important改为importantly。
9．been→be 考查动词。此处be与believe是并列的谓语动词，共用一个情态动词must，所以要用原形，been改为be。
10．去掉 more 考查副词。副词hard 的比较级是harder，more多余，故去掉more。

答案与解析
本文是一篇记叙文。在美国活跃着像Larry这样的一群有爱心的人士，他们拿出自己的私人飞机，专门接送病人到医疗中心接受治疗。
1．D 根据下文出现的volunteer pilots可知，病人家属打电话，希望得到他们的帮助，用飞机把他们的病人送到离家很远的地方去接受治疗。这里表示“飞行”，要用flight。suggestion“建议”，method“方法”，introduction“介绍”，均不符合语境。
2．C 根据语境，Larry从来不(never)拒绝这些人的任何请求。
3．C 根据语境，他同时帮助这些需要帮助的病人(patients)，这从上文中的“from families of very sick people”可得到暗示。
4．B 分析句子结构可知，空处引导宾语从句，并在从句中作宾语，故用what。
5．A 根据下文中的“they're__6__out of money，out of time，and out of faith”可知，他们没有钱，没有时间，没有信念，这就是他们人生中最令人恐惧的时期，故选frightening。下文中的fear也是提示。
6．D 根据语境和空后的out of可知，应选running。run out of表示“用完，耗尽”。
7．B 他有时亲自驾驶飞机接送病人，同时还负责安排时间表、募集资金等事宜。表示“当……时候”，要用while, while从句中省略了主语和be动词。
8．C 根据前面提到的“安排时间表、募集资金”可知，这里用responsibility表示“职责，责任”。因此选C。possibility“可能”，incident“事件”，game“游戏”，均不符合语境。
9．C 根据上文中的dramatic(激动人心的)healing可知，他们用(未来)激动人心的治疗和希望(hope)来打消病人的恐惧。
10．A 根据下文中的“After they sold it，they received a large sum of money”可知，他们把救护公司卖掉之后，获得了一大笔钱，由此可知他们的公司很成功。故选successful。
11．B 根据上文中的“who sometimes pilots some trips himself”可知，此处说的是开飞机的执照(permit)。
12．D 根据语境，此处指一篇关于一个飞行员用飞机送一个病人的文章。所以用about“关于”。
13．A 读完这篇文章，他的心中立刻(immediately)就有了一个目标。
14．C 根据语境，Larry如今依靠一个将近有500名志愿飞行员的强大体系支撑着自己这个团队的运转。rely on表示“依靠”。
15．B 根据上文中的“Larry's crew on the ground”和空后的“to and from the airport”可知，他们在地面上工作，往返于机场，因此这里说的是地面人员来回接送病人，因此选B，意思是“驾车送”。
16．A 根据语境，病人与这些飞行员之间的联系可以持续数周、数月或者更久，因此选Links，表示“联系”。
17．B 参见上题解析。
18．D 一位癌症病人在十多年的时间里有超过585回的接送，使用trip使文章显得更生动。
19．B 文章前面提到募集资金，因此这里表示病人的每一趟接送都是免费的(free)。
20．A 根据上文中的“We help replace the fear with dramatic(激动人心的)healing”可知，这里说的是担忧，病人不愿意跟家人谈论自己对病情的担忧。因此选A。
Ⅲ.七选五
All animals are part of the food chain: they are listed on someone else's menu and always run the risk of ending up as someone else's lunch, dinner or snack.__1__
Many animals have adapted to their environment in such a way that they can hide better.Having the right colour can make a big difference.__2__Some can change colour very quickly, even in a few seconds, making it more difficult for other animals to find them.__3__Some insects look just like a small stick and can easily hide in a tree or bush.
If it is too late to hide or run away, an animal must use other methods to survive an attack.One type of snake that lives in Texas has developed an interesting way to defend itself.If it is attacked, it first makes itself look bigger and pretends to be a dangerous snake.If that doesn't work, the snake uses another trick: it rolls over, opens its mouth and acts as if it were dead.The snake is such a good actor that it seems quite dead.__4__However, if you roll it back on its stomach, it will roll over on its back again in order to look dead.
__5__Many animals stay together in large groups and use sounds and body language to warn each other if they see or hear something suspicious.Some animals even work together with other species to stay safe.The birds you often see on the back of a water buffalo have an important job: they help warn the buffalo of danger.
A．Useful body parts help other animals and insects a lot.
B．Like human beings, animals often try to hide or run away when they are being attacked.
C．Other animals and insects have a body shape that helps them hide.
D．To survive in the wild, many animals have developed clever ways to escape from or avoid danger.
E．The best way to stay safe is to develop a way to receive an early warning when danger comes.
F．Many animals have the same or similar colour as their environment.
G．If someone picks it up, it hangs like a rope and doesn't move.
答案与解析
本文主要介绍动物为了防止弱肉被强食，八仙过海各显神通。
1．D 文章主旨句。分析本文的结构可知，此处应为文章主旨句。此题最大的干扰项是B。由上下文可知“隐藏或是逃跑”只是动物们求生存的手段之一，第三段及第四段还介绍了其他的方法， 如“装厉害”“装死”“合作预警”等等，B做文章主旨句不合适。
2．F 细节支撑句。“Many animals have the same or similar colour as their environment”是通过举例子解释前一句，因此综合分析我们可知F正确。
3．C 上下文过渡句。这一段介绍动物通过不同的办法——颜色，外形——隐藏自己。“Some insects look just like a small stick and can easily hide in a tree or bush.”这一句是对前一句的进一步解读，由此可知C正确。
4．G 细节支撑句。从该段的结构分析“However, if you roll it back on its stomach, it will roll over on its back again in order to look dead.”，“However”暗示上文与之不同的情况，因此可知G正确。
5．E 段落主旨句。由下文中的“to warn each other” “they help warn the buffalo of danger”可知E正确。
Ⅳ.语法填空
I take the train to work every morning.There is rubbish thrown away everywhere in the railway station，__1__terrible smell is more than I can put up with.So I always try to rush through it.The other day I was trying to do so as usual__2__something made me stop for a moment.I saw the most beautiful act of__3__old lady walking in front of me.

I want to follow her example.I hope people will do the same as I do.If everyone makes contributions__9__protecting the environment, there will be less pollution and the world will become__10__(clean) and more beautiful.
答案与解析
1．whose 此处是非限制性定语从句，修饰先行词rubbish, whose在从句中作定语。
2．when 句型sb.was doing sth.when ...意思是“某人正在做某事，这时……”。
3．an an old lady此处意思是“一位老太太”。
4．Supported Supported by a white stick是过去分词短语作状语，分词动作support与逻辑主语the old lady之间是动宾关系。
5．difficulty 空格中所填单词在句中作介词with的宾语，需用difficult的名词形式。
6．It It指代前面老太太做的事。
7．was moved 作者是被感动的，且发生在过去，故用一般过去时的被动语态。
8．thinking 考查固定结构couldn't stop doing sth.意为“情不自禁做某事”，符合语境。
9．to make contributions to...是习惯搭配，意思是“为……做贡献”。
10．cleaner 由该句中后面and more beautiful可知，这里的clean也应该用比较级形式。
Ⅴ.书面表达

Dear_Tom,_
How are you doing? I wonder if you could sell some Chinese knots for me.I made them myself with red silk threads, cloth and other materials.They look really beautiful in the shape of a diamond, about 5 inches long and 4 inches wide.In China, these knots stand for friendship, love and good luck.People can either give them as gifts to friends or hang them in their houses.They are only 12.99 US dollars each.If anyone wants to know more about the knots, let them write to me.Also, do let me know if you need further information.Thank you!
Yours，
Li_Hua
