内化读文技法
明晰所至,把握所感
本文是一篇游记。游记一般以游览路线为线索,随着时间的推移、空间的转移依次记述游览过程中所见到的景物,并抒发自己的感受和体验。读文时,应按照作者的游览过程,明晰作者所到之处,也就是作者的游踪。同时,把握作者在游览过程中所获得的感受——可以通过直接表现心理、感受、思想、情感方面的关键词,也可以借助反映作者内心情感的语言、行动、表情之类的描写把握作者的所思所感。如本文作者描写了自己乘坐火车进藏的“天路”之旅,在描写青藏铁路沿线风景的同时,回顾了建设者们在青藏铁路修建过程中,始终以生态保护为前提,克服重重困难,最终建成这条“不可能建成的”铁路的历程,同时表达了自己作为其中一名建设者的自豪之情。
(一)赏用词之妙
1.Sitting back in my seat, I can't quite believe that I'm about to travel along the railway that many foreign experts claimed was “impossible”.
赏析:本句中的can't quite believe写出了作者内心的激动:即使人已在火车上,仍不敢相信这一事实。后半句中的impossible一词加了引号,说明尽管修建青藏铁路的难度很大,但对于勇敢无畏的铁路工人来说没有什么是不可战胜的。
2.The train has been racing along steadily since it left Xining.
赏析:此处的race一词为名词动用,写出了火车速度之快;steadily则描写了行驶之稳。简单的两个词描绘了火车在青藏线上平稳快速向前行驶的景象。
3.A group of Tibetan antelopes is moving under the bridge, with some stopping to eat grass at their leisure.
赏析:句中动词move, stop, eat的使用,化静态为动态,让描绘的画面更加生动鲜活,增加了语言的灵动性。
4.The journey has been flying by, and before I know it, we have reached Tanggula Station.
赏析:句中的 flying by和before I know it形象地描述了火车的速度之快,旅程之便捷、舒适,也从侧面印证了铁路工程质量之高。
5.Using thousands and thousands of sandbags, we built a twenty kilometre wall along the lake to protect it from construction waste.
赏析:句中的thousands and thousands of及 twenty kilometre从侧面描写了工人们为保护措那湖所做的努力。
①Standing on the podium, ____________________________________.
站在领奖台上,我仍然不敢相信,我做到了。
②They __________________________ towards the finishing line.他们正争先恐后地向终点冲去。
③Miss Wang's class was so wonderful that forty five minutes ____________________________.
王老师的课是如此精彩,以至于不知不觉间四十五分钟的时间飞逝而过。  
(二)赏句式之高
1.Taking years to complete, the Qinghai Xizang Railway is a record of all of our efforts to overcome the most difficult engineering challenges.
赏析:本句中运用了分词作状语以及不定式作后置定语,言简义丰地讲述了青藏铁路历时数年建成,凝聚着铁路工人攻克种种工程难题的全部心血。
2.Water birds playing in the lake, and cattle and sheep wandering the grasslands bring the scenery to life.
赏析:本句中采用了动名词的复合结构作主语,栩栩如生地刻画了水鸟在湖面嬉戏,牛羊在草原游荡的生动画面。
①________________________, she gazed at her surroundings with large, innocent eyes.(分词短语作状语)
她快乐地唱着歌,用一双天真的大眼睛注视着周围的环境。
②________________________ is not smooth, and it is full of challenges and difficulties, which we should be brave to face.(不定式作后置定语)
去实现成功的道路不会平坦,充满了挑战和困难,我们应该勇敢地面对它们。  
(三)赏描摹之韵
1.(场景描写)The first landmark to catch my eye is the splendid Qingshuihe Bridge, the world's longest bridge built over permafrost.Look! A group of Tibetan antelopes is moving under the bridge, with some stopping to eat grass at their leisure.
赏析:此处的catch my eye及Look, is moving采用了动态的手法来描写清水河大桥的景色,生动地呈现出作者乘坐火车浏览着窗外美丽的高原风光的画面。第二句中的with复合结构丰富了画面的细节,让读者犹如亲见,at their leisure则暗示了在修建铁路时也给予了当地环境充分的保护。
2.(写作手法)To prevent damage to wetlands and grasslands, 675 bridges with a total length of about 160 kilometres were built between Golmud and Lhasa.We even moved 140,000 square metres of wetland to a new area in order to protect its distinct ecosystem.
赏析:本段运用了列数字的写作手法,客观严谨地呈现了为避免破坏湿地和草原,人们在青藏铁路的修建过程中所作出的种种努力。体现了语言的准确性,让文章内容更具说服力。
(四)赏修辞之功
The words “railways like massive dragons are winding among the mountains” seem particularly vivid as I travel across the “roof of the world”.
赏析:此处使用了借代修辞,借roof of the world代指青藏高原,突出了青藏高原的鲜明特征,语言精练别致,增添了文章的美感。
①The book was translated by several hands.

Ⅰ.阅读理解
A
I first realized that plastic was a serious matter for our planet during my travel in Western Australia.One day about 12 years ago.I stopped at a supermarket along the Coral Bay coast to buy some groceries.
But the lady at the counter told me that the supermarket didn't sell any shopping bags to prevent plastic in the ocean and help preserve the endangered turtles (海龟) living in that area.After a first reaction of surprise, I gathered all purchases in my arms and left, reflecting on what I had been told.
The experience in that trip made me more conscious about my impact and pushed me to adopt various habits to travel and live more sustainably. For example, I always carried a cotton bag when I went shopping.
My travel to Indonesia was another life-changing experience that strengthened my determination to turn to a zero-waste lifestyle.In Indonesia, finding safe drinkable water was always a challenge, so I traveled with my water bottle, managing to avoid almost entirely the use of plastic during my trip.
However, I was seriously struck by my stay on the Libaran Island, where a sustainable and turtle conservation project was launched 10 years ago.Despite the big efforts by the project staff and the community in cleaning up the beaches and creatively reusing plastic, the shore was washed daily with tons of plastic coming from the tides.Walking on a carpet of plastic that almost prevented me from seeing the beach underneath was quite shocking.
Facing this global issue in person, I felt a sense of sadness and anger that soon turned into determination: to do as much as possible to reduce plastic in my life.Sometimes we might feel helpless in front of big problems, but we should be aware that small changes could actually make a difference step by step!
语篇解读:本文是一篇夹叙夹议文。作者在旅行中意识到塑料污染的严重性,随后决定通过采取可持续的生活方式来减少塑料的使用。
1.How does the author lead in the topic of the text
A.By reflecting on the present life.
B.By looking into the future environment.
C.By introducing the previous achievements.
D.By recalling the past shopping experience.

解析:写作手法题。根据第一段首句可知,文章一开始作者回忆起12年前在澳大利亚的旅行中的一次购物经历,这次经历让作者意识到塑料对地球的影响。由此推知,作者通过回忆过去的购物经历引入了文章的主题。
2.What did the author decide to do after the trip about 12 years ago
A.Cut back on travel. B.Shop less frequently.
C.Lead a green life. D.Purify drinking water.
解析:细节理解题。根据第二段中的“The experience in that trip ...and live more sustainably.”可知,通过这次旅行,作者决定过一种绿色生活。

3.What do we know about the project in paragraph 4
A.It had no clear goal.
B.It didn't work out very well.
C.It met the islanders' needs.
D.It was intended to prevent turtle attacks.

解析:推理判断题。根据第四段中“Despite the big efforts by the project staff ...daily with tons of plastic coming from the tides.”可知,尽管活动的工作人员和社区在清理海滩,可是每天还是会有成吨塑料。由此推知,该活动收效甚微。
4.What does the author think of the plastic problem
A.It is permanent.
B.It is manageable.
C.It is easy to solve.
D.It is lacking in attention.

解析:推理判断题。根据最后一段中的“ we should be aware that small changes could actually make a difference step by step!”可知,作者相信小的改变一定可以产生大的影响。由此可知,作者认为塑料问题一定是可以解决的。
B
When Anika Puri visited India with her family four years ago, she was surprised to come across a market in Bombay filled with rows of ivory jewelry and statues.Globally, ivory trade has been illegal for more than 30 years, and elephant hunting has been prohibited in India since the 1970s.
“I was quite shocked,” the 17-year-old from New York, recalls, “Because poaching (偷猎) is illegal, how come it is still such a big issue?”
Curious, Puri did some research and discovered a shocking statistic:Africa's forest elephant population had declined by about 62 percent between 2002 and 2011.Years later, the numbers continued to drop.Puri, a wildlife lover, wanted to do something to help protect the species and others still threatened by poaching.
Over the course of two years, Puri created a low-cost machine learning-driven software that analyzes movement patterns in thermal infrared (热红外) videos of humans and elephants.Puri says the software is four times more accurate than existing state-of-the-art detection methods.It also eliminates the need for expensive high-definition thermal cameras, which can cost thousands, she says.The software uses a $250 thermal camera with 206 * 156 resolution that plugs into an off-the-shelf phone.The camera and the phone are then attached to a drone (无人机), and the system produces real-time inferences as it flies over parks as to whether objects below are humans or elephants.
Its potential impact on society earned her the Peggy Scripps Award for Science Communication.“Research isn't a straight line,” Puri says.“It makes me resourceful.It helps me develop into a more creative thinker.”
语篇解读:本文是一篇记叙文。主人公Anika Puri 在与家人外出旅行中偶然间发现盗猎大象的现象,于是她通过观察和研究,发明了一种软件来帮助保护大象。
5.What inspired Anika Puri to make the invention
A.One study trip to Bombay.
B.The deep passion for law.
C.One visit to India.
D.Her love for ivory.

解析:细节理解题。根据第一段以及第三段中的“Puri, a wildlife lover, wanted to do something to help protect the species and others still threatened by poaching.”可知,当Anika Puri和家人一起访问印度时,发现了市场里摆满了成排的象牙珠宝和雕像,由此激发了她想要保护大象的决心。
6.How does the author explain the situation of Africa's forest elephant
A.By listing figures.
B.By making comparison.
C.By showing an example.
D.By referring to some former studies.
解析:写作手法题。根据第三段第一句可知,作者通过列举数字的方式介绍了非洲森林大象的情况。

7.What's the research like in Anika Puri's eyes
A.It's tough and can't reach the goal.
B.It's beneficial to one's development.

Ⅱ.阅读七选五
In the face of wildlife loss and habitat destruction, it's easy to feel powerless to improve.But any action you take, no matter how small, will help restore the world to its natural balance.Here are 4 things you can do to help wildlife.
Think twice before landscaping.
9 But unless you're confronting a genuine safety issue, remember that what's unpleasant to you is sweet home to squirrels, birds, worms and other animals that you might not even know are there.If you must landscape your yard, do so in a way that won't drive away native wildlife.
Keep your cats indoors.
It's ironic that many people who claim to love wildlife have no problem allowing their cats to roam (闲逛) freely outside.Cats are animals, too. 10 Outdoor cats, however, don't think twice about killing wild birds.In case you're thinking about “warning” the birds by attaching a bell to your cat's collar, don't bother: Birds have an inborn tendency to flee loud, startling noises, not jingling pieces of metal.
Don't feed any animals but birds.
That deer that wanders into your backyard might look hungry and helpless. 11 Giving food to animals accustoms them to human contact, but not all human beings are as warm-hearted as you are.Feeding wild birds, on the other hand, is OK as long as you don't have outdoor cats and you provide a meal in keeping with the bird's natural diet. 12
Clean up litter (not only your own).
If you're concerned about protecting wildlife, you know better than to litter.But it's not enough to keep your own yard or picnic area clean.You should go the extra mile and pick up cans and bottles left by other people. 13
A.Choose nuts and seeds rather than processed bread.
B.It seems cruel to keep them shut up inside the house.
C.However, if you feed it, you won't be doing it any favors.
D.Most people don't want wild animals to destroy their roses.
E.Small animals can easily get trapped in or injured by this litter.
F.If you have the space, establishing a “mini meadow (草地)” as a border or boundary area is another effective way to attract birds, as well as beneficial insects.
G.If you have just purchased a house or a piece of land, you might be tempted to chop (砍) down unsightly trees.
语篇解读:本文是一篇说明文。文章主要介绍了为了帮助野生动物,你可以做到的四件事。
9.选G 结合小标题“Think twice before landscaping.”与本段最后一句可知,本段建议大家在改造住所时,要考虑到对周围野生动植物的影响。由下文中的But可知,上下文是转折关系。G项“如果你刚买了房子或者一块地,你可能会忍不住去砍倒那些难看的树木。”符合语境,其中的“chop (砍) down unsightly trees”就是landscaping的具体做法。
10.选B 下文“Outdoor cats, however, don't think twice about killing wild birds.”指出,把猫放出去,它们会吃野生动物。由however可知,前后句子是转折关系,故选项B“把它们关在屋子里似乎很残忍。”符合语境,且选项B中的keep them shut up inside the house呼应本段标题“Keep your cats indoors.”。
11.选C 根据本段小标题“Don't feed any animals but birds.”可知,要保护动物,我们就要克制住给野生动物喂食的想法。结合空前一句可知,跑到你家后院来的野生鹿看起来很饿、很无助,但是也不应该喂它们。C项“然而,如果你喂它,不会给它带来任何好处。”呼应本段主题,符合语境。
12.选A 此处前一句提到,给野生鸟类喂养与它们食谱中一致的食物是可以的,那就意味着尽量给它们喂食纯天然未经加工的东西,A项“选择坚果和种子,而不是加工过的面包。”符合语境。
13.选E 此段的小标题“Clean up litter (not only your own).”告诉我们,要保护野生动植物,我们要做的不仅是随时清理自己产生的垃圾。上文“You should go the extra mile and pick up cans and bottles left by other people.”指出,我们要捡起别人留下的易拉罐和瓶子。空处承接上文,指出这么做的原因,即能保护野生动物,E项“小动物很容易被这些垃圾困住或因此受伤。”符合语境。UNIT 6 课时检测(一) “Understanding ideas”的课文习读环节

A
I first realized that plastic was a serious matter for our planet during my travel in Western Australia.One day about 12 years ago.I stopped at a supermarket along the Coral Bay coast to buy some groceries.But the lady at the counter told me that the supermarket didn't sell any shopping bags to prevent plastic in the ocean and help preserve the endangered turtles (海龟) living in that area.After a first reaction of surprise, I gathered all purchases in my arms and left, reflecting on what I had been told.
The experience in that trip made me more conscious about my impact and pushed me to adopt various habits to travel and live more sustainably.For example, I always carried a cotton bag when I went shopping.
My travel to Indonesia was another life changing experience that strengthened my determination to turn to a zero waste lifestyle.In Indonesia, finding safe drinkable water was always a challenge, so I traveled with my water bottle, managing to avoid almost entirely the use of plastic during my trip.
However, I was seriously struck by my stay on the Libaran Island, where a sustainable and turtle conservation project was launched 10 years ago.Despite the big efforts by the project staff and the community in cleaning up the beaches and creatively reusing plastic, the shore was washed daily with tons of plastic coming from the tides.Walking on a carpet of plastic that almost prevented me from seeing the beach underneath was quite shocking.
Facing this global issue in person, I felt a sense of sadness and anger that soon turned into determination: to do as much as possible to reduce plastic in my life.Sometimes we might feel helpless in front of big problems, but we should be aware that small changes could actually make a difference step by step!

When Anika Puri visited India with her family four years ago, she was surprised to come across a market in Bombay filled with rows of ivory jewelry and statues.Globally, ivory trade has been illegal for more than 30 years, and elephant hunting has been prohibited in India since the 1970s.
“I was quite shocked,” the 17 year old from New York, recalls, “Because poaching (偷猎) is illegal, how come it is still such a big issue?”
Curious, Puri did some research and discovered a shocking statistic:Africa's forest elephant population had declined by about 62 percent between 2002 and 2011.Years later, the numbers continued to drop.Puri, a wildlife lover, wanted to do something to help protect the species and others still threatened by poaching.
Over the course of two years, Puri created a low cost machine learning driven software that analyzes movement patterns in thermal infrared (热红外) videos of humans and elephants.Puri says the software is four times more accurate than existing state of the art detection methods.It also eliminates the need for expensive high definition thermal cameras, which can cost thousands, she says.The software uses a D|S250 thermal camera with 206 * 156 resolution that plugs into an off the shelf phone.The camera and the phone are then attached to a drone (无人机), and the system produces real time inferences as it flies over parks as to whether objects below are humans or elephants.
Its potential impact on society earned her the Peggy Scripps Award for Science Communication.“Research isn't a straight line,” Puri says.“It makes me resourceful.It helps me develop into a more creative thinker.”
5.What inspired Anika Puri to make the invention
A.One study trip to Bombay.
B.The deep passion for law.
C.One visit to India.
D.Her love for ivory.
6.How does the author explain the situation of Africa's forest elephant
A.By listing figures.
B.By making comparison.
C.By showing an example.
D.By referring to some former studies.
7.What's the research like in Anika Puri's eyes
A.It's tough and can't reach the goal.
B.It's beneficial to one's development.
C.It really requires a variety of resources.
D.It should be further developed because of the need.
8.What may be the best title of the text
A.Poaching Is a Shocking Problem
B.Drones Were Applied to the Ban on Poaching
C.A Fantastic Discovery Was Eventually Made by a Brilliant Teenager
D.A Teenager Invented a Low cost Tool to Spot Elephant Poachers in Real Time
