本文的语篇类型为叙事记叙文。此类记叙文通常包括三部分：首先交代事情的背景和起因(who, what, where, why)，然后叙述事情的经过(development)，最后陈述事情的结果(ending)。如本文以“分—总”的结构记叙了一名自然摄影师在美国黄石国家公园的一次惊心动魄的拍摄经历。文章的行文脉络是“作者的工作简介→介绍黄石国家公园→在黄石公园里遇到熊的经历→作者的感受(总)”。
阅读时还可梳理情节线，更好地把握文章内容。如本文的情节线为“Last spring in Yellowstone, I followed a path →I was concentrating on photographing→only metres away from me was a bear→I captured an image of the bear→the bear turned and ran back into the forest”。另外，需关注主旨升华部分。如本文尾段作者表达了尊重野生动物、与自然和谐相处的感悟。
(一)赏用词之妙
1．Slowly, and with the camera still held to my eye, I turned ...and froze.
赏析：本句使用了副词slowly和with复合结构作状语，描述了作者转身时的状态，犹如动作慢镜头一般将当时的场景展现在读者面前。在转过身后，看到就在自己几米外有一只熊时，作者用了froze一词生动地展示了自己当时的反应和内心的恐惧。
2．My legs started shaking.Somehow, I forced my finger to press the button.
赏析：句中的force一词，形象地刻画出作者虽然非常害怕，腿在颤抖，但是出于一名摄影师对工作的热爱，大脑还是发出指令，命令手指做出了行动，按下了快门，将这一幕保存了下来。force一词不但描写了动作，也把作者的心理状态描写得淋漓尽致。
3．My most frightening but magical experience was now captured forever in a single image.
赏析：作者使用了两个形容词frightening 和magical精准凝练地对这次经历做了总结，可怕的是近距离地遇到了熊，九死一生；神奇的是留下了熊的照片，相当珍贵。
①(用所给词的适当形式填空)__________ (slow), things began to improve.
②(完成句子)When she heard this, ____________ on her lips.
听到这些话，她脸上的笑容僵住了。
③(完成句子)She managed to ________________ and then turned away.
她勉强笑了笑，然后转身离开了。
(二)赏句式之高
1．Only metres away from me was a bear.With water falling off its thick, brown hair, the bear stared back at me.
赏析：第一句使用了完全倒装的表达方式，凸显了作者与熊的距离之近，烘托了紧张的气氛。第二句中with复合结构以及形容词thick, brown的使用，生动地展现了熊的外貌——厚厚的棕色皮毛滴着水珠，同时也暗示了熊突然出现的方式。
2．Time stood still as the bear and I both waited to see who would move first.
赏析：句中使用了as引导的时间状语从句，形象地刻画出作者看到熊之后的反应：感觉时间仿佛凝固了。后半句中使用了who引导的宾语从句，写出人类与熊之间的心理博弈。
①____________________________________， which has a history of 1,000 years.在远处耸立着一座古老的寺庙，它有着上千年的历史。
②Close to the school gate lies our newly built library ______________________________.
我们新建的图书馆坐落在学校门口附近，周围有许多绿树环绕。
③____________________， I developed a preference for sports.
随着时间的推移，我养成了对体育运动的偏爱。
(三)赏文笔之美
Last spring in Yellowstone, I followed a path that took me through a dark forest.When I finally stepped out of the trees, the view was breathtaking.An eagle flew over the snow capped mountains，which were reflected in the still lake below.
赏析：作者先是描写了自己沿着一条小路走进幽暗的森林，渲染了宁静的氛围。然后笔锋一转，走出森林，视野顿时开阔起来，眼前是白雪皑皑的山峰，平静的湖面，在这幅水墨画上，又有鹰掠过山顶，留影于湖边。描写动静结合、虚实呼应，在读者的眼前展开了大自然壮丽而神奇的画卷。

Ⅰ.阅读理解
A
For the first time, a causal link has been established between climate change and the timing of a natural event — the appearance of the common brown butterfly.
Although there have been strong connections between global warming and changes in the timing of events such as animal migration and flowering, it has been hard to show a cause-and-effect link.This is what Michael Kearney and Natalie Briscoe of the University of Melbourne, Australia, have now done.
The researchers compared temperature changes in Melbourne — where the butterfly is common — with recorded observations of the first brown butterfly to be seen in the spring since the 1940s.With each of the past ten years, the butterflies appeared 1.6 days earlier and Melbourne heated by 0.14℃.Overall, the butterfly now appears on average 10.4 days before it did in the 1940s.
The pair are confident in the relationship for two reasons.First, they placed eggs of the butterfly in special boxes, where temperature could be controlled, and found that each larval (幼虫的) stage had a different response to warmer-than-normal conditions.“The egg, which is laid in late summer, and the first larval stage do well at high temperatures，” says Kearney.
“The second to the fifth stages occur in winter and can't survive high temperatures.”The knock-on effect is that the larval pupates (化蛹) earlier and the butterfly appears sooner.Second, they made a mathematical model combining these physiological effects of temperature on development with climate data.The model precisely matched the observed changes in butterfly emergence date.
The researchers used several climate models to find out what is likely to have caused the rise in Melbourne's temperature, and ruled out the possibility that natural weather events could account for the warming.
语篇解读：本文是一篇说明文。文章主要介绍了随着气候的改变，动物的习性也会有所改变。蝴蝶出现得比以往早，就是因为气候变暖。
1．What is the relationship between the rise in temperature and the butterfly appearance
A．They are linked in a difficult way.
B．They are related in a cause-and-effect way.
C．They have a direct relationship with each other.
D．They have no connection with each other.
√
解析：细节理解题。根据第一段可知，这是第一次在气候变化和自然事件——普通棕蝶的出现——发生的时间之间建立了因果关系。由此可知，温度的上升和蝴蝶的出现有因果关系。
2．Why were the researchers confident about their finding
A．They had used the most advanced equipment in the world.
B．Their finding got support from the textbooks.
C．The results of their study is based on expert judgement.
D．Their experiment proved their previous guessing.
√
解析：细节理解题。根据第三段最后两句可知，在过去的十年里，蝴蝶的出现时间每年提前1.6天，墨尔本气温也升高了0.14 ℃。总的来说，现在的蝴蝶平均出现时间比20世纪40年代早了10.4天。再根据第四段内容可知，研究人员对他们的发现充满信心，是因为他们的实验证实了他们先前的猜测。
3．What does the underlined part “The knock-on effect” in paragraph 4 mean
A．The effect caused by the thing that happened before.
B．The effect of things that happened at the same time.
C．The effect of one thing causing the other long after.
D．The effect of one thing causing the other quickly.
√
解析：词义猜测题。根据画线部分下文“the larval pupates (化蛹) earlier and the butterfly appears sooner”可知，蚕化蛹比以往早，变成蝴蝶也比以前快，说明是指以前发生的事情所造成的影响。故画线部分意思是“以前发生的事情造成的影响，即引起了连锁反应”。
4．What can be inferred from the text
A．The exact reason for Melbourne's temperature rise is very clear.
B．Climate models cannot exactly show climate change in history.
C．The timing of the butterfly appearance will be earlier with increased warming.
D．The rise in temperature decides the possibility of natural weather events.
√
解析：推理判断题。根据第三段最后两句可推断出，蝴蝶出现的时间会随着气候变暖而提前。
B
AI has been applied widely in a national park in northwestern China to track snow leopards (雪豹)．
The AI-aided digital toolbox can tell snow leopards in Gansu Province's Qilian Mountains National Park from other wildlife, using images captured by infrared (红外线的) cameras.
Located around 3, 500 meters above sea level, the Qilian Mountains, with a large area of bare rocks sticking out from the grass, provide a favorable habitat for snow leopards.Though more than 200 cameras have been fixed in the area, sorting out relevant (有关的)information has not been easy for researchers.“To conduct further studies on the population, distribution and activities of the snow leopards, the cameras capture hundreds of thousands of videos and photos every quarter，” said Ma Duifang,
who works for the Administration Bureau of Qilian Mountains National Park.“Even a slight movement in the environment, such as a pleasant wind blowing over the grass, can trigger (启动) the cameras.Sometimes, curious wildlife knock into the device, triggering the cameras, which take pictures of mere clouds.” Ma and his workmates had to go through each video, and information about the animals that appeared in the images also required human efforts.So it often took them several weeks to complete these tasks.
Thanks to AI technology, researchers in the Qilian Mountains National Park no longer need to rack their brains in search of snow leopards hiding in the wild.“The forest keepers can now locate a snow leopard from 1,000 pictures in only about 20 minutes, much faster than before，” said Huang Xiangqi, one of the technology's developers.“We hope we can combine monitoring data with field investigations to help researchers identify the snow leopards so as to draw up a more specific plan for their protection.”
语篇解读：本文是一篇新闻报道。文章讲述的是人工智能辅助技术可以更好、更快地处理数据，从而促进对雪豹的保护。
5．Why is it hard for researchers to sort out relevant information
A．The mountain is high.
B．Snow leopards run too fast.
C．They are badly in short of workmates.
D．There are many irrelevant videos and photos.
√
解析：细节理解题。根据第三段中的“Even a slight movement ...take pictures of mere clouds.”可知，摄像机会由于外界影响拍摄到很多没有用的照片。
6．How does the AI-aided digital toolbox help the researchers
A．By searching for snow leopards in the forest.
B．By making data processing quicker and easier.
C．By controlling the movements of snow leopards.
D．By recording snow leopards' changing populations.
解析：细节理解题。根据最后一段中的“The forest keepers can now ...one of the technology's developers.”可知，AI-aided digital toolbox通过提高数据加工过程的效率来帮助这些研究人员。
√
7．Which of the following is a suitable title for the text
A．Snow Leopard — the Most Important Animal in Gansu
B．Ma Duifang — a Leading Expert in Snow Leopard Study
C．Infrared Camera — a Creative Invention for Wildlife Protection
D．AI-aided Technology — an Effective Helper in Snow Leopard Protection
√
解析：标题归纳题。根据第一、二段内容可知，本文讲述的是人工智能辅助技术可以更好、更快地处理数据，从而促进对雪豹的保护。故D项“人工智能辅助技术——雪豹保护的有效助手”可以作为本文标题。
8．The text is likely to be .
A．a news report
B．a scientific paper
C．an official document
D．a product introduction

How to Protect Wildlife
Wildlife faces threats from habitat destruction, pollution, and other human actions.Although protecting wildlife may seem too hard at times, even small actions can help protect many different animals. 9
Create wildlife-friendly areas.When trying to make your garden more beautiful, choose plants that can provide food and shelter to native wildlife.This will also help cut down on pollution. 10
11 By using less water and fewer fuels, you will be helping to protect the wildlife around you.Take buses or the subway when you can and turn off electric devices when you're not using them.
Buy products that are wildlife-friendly. 12 Keep in mind that some endangered animals are killed by traps, catches or hunters who are after other wildlife within the same habitat.
Limit family size.Population growth is one of the major factors in habitat destruction.With the rapidly growing population, more and more habitats for wildlife are occupied by humans. 13 In this way, the Earth's population will stabilize and native habitats can be protected.
A．Live a greener life.
B．Donate money to organizations.
C．Each family should be limited to one or two children.
D．Avoid products that are made from endangered animals.
E．Protecting wildlife from being endangered is every family's duty.
F．Here are some tips on how to protect wildlife through small actions.
G．Build bird houses to your garden or yard to attract and shelter these species.
语篇解读：本文是一篇说明文。文章就如何保护野生生物，提出可以践行的力所能及的小事，并希望读者也贡献自己的一份力量。
9．选F 上文提到小的举动也能起到保护野生生物的作用，下文则介绍了一些具体的方法。F项“这里是一些关于如何通过小的举动保护野生生物的方法”在此处承上启下。故选F项。
10．选G 该段讲的是创造适合野生生物生存的环境。G项“在庭院安设鸟房来吸引、保护这些物种”符合段落主题。故选G项。
11．选A 下文提到要保护水资源、乘坐公共交通、节约水电等一些绿色生活方式。A项“过更绿色的生活”作为主题句最能概括此段主旨。故选A项。
12．选D 空白处承接段首主题句“购买野生生物友好型产品”，也就是要我们拒绝购买由野生生物制成的物品。因此D项“避免购买由濒危动物制成的产品”符合语境。故选D项。
13．选C 本段主题是限制家庭成员规模。人口过多会占据野生生物的栖息地，空白处下一句也指出了这种方法的好处，C项“每个家庭限制生一到两个孩子”上下连贯，符合主题。故选C项。UNIT 5 课时检测(四) “Developing ideas”的课文习读环节

9．选F 上文提到小的举动也能起到保护野生生物的作用，下文则介绍了一些具体的方法。F项“这里是一些关于如何通过小的举动保护野生生物的方法”在此处承上启下。故选F项。
10．选G 该段讲的是创造适合野生生物生存的环境。G项“在庭院安设鸟房来吸引、保护这些物种”符合段落主题。故选G项。
11．选A 下文提到要保护水资源、乘坐公共交通、节约水电等一些绿色生活方式。A项“过更绿色的生活”作为主题句最能概括此段主旨。故选A项。
12．选D 空白处承接段首主题句“购买野生生物友好型产品”，也就是要我们拒绝购买由野生生物制成的物品。因此D项“避免购买由濒危动物制成的产品”符合语境。故选D项。
13．选C 本段主题是限制家庭成员规模。人口过多会占据野生生物的栖息地，空白处下一句也指出了这种方法的好处，C项“每个家庭限制生一到两个孩子”上下连贯，符合主题。故选C项。
