Ⅱ. 阅读理解

主题：人与自然（自然环境）　话题：《我们的星球》　体裁：说明文　建议用时：6＇

Years ago, the wildlife documentary(纪录片) Planet Earth took us on an amazing journey from deep caves to the rainforests and then to the bottom of the ocean. After that, a new documentary Our Planet shows different animals and the influence of humans on the natural world.

The US entertainment company Netflix made the eight-episode(集) journey meet its audience(观众). The crew(工作人员) of the documentary covered 50 countries and areas to choose the best filming places, and took more than four years to produce it. It is the hard work of more than 600 crew members.

With the latest 4K video technology, the documentary allows audiences to have a sharp new look at nature. “People are given a better chance to get themselves into the lives of the animals,” said Fothergill, one of the documentary’s producers.

Apart from showing Earth’s beauty in new detail, the documentary also shows the planet’s poor climate conditions. “Our Planet is here to say, ‘The planet is dying, and we’re killing it.’” Fothergill said. In one sad scene, hundreds of walruses(海象), half-blind, go out of the water, fall down a rock to suffer a painful death on the beach below. It shows how man-made global warming has destroyed their natural habitat(栖息地) and explains why they’ve been forced to find a safe place on the rocks.

However, it’s not all about sadness. The documentary also talks about success stories, including Siberian tigers, blue whales and hump-back whales. These species are protected thanks to international agreements on environmental protection. It reminds us that we can change the present bad condition of our planet through our joint(共同的) effort.

Calling on more people to take action to protect our planet is the final goal of the new documentary. What we do in the next 20 years will decide the future of all life on Earth.

1. What is the new documentary Our Planet about?

A. An amazing journey of rainforests.

B. The beauty and customs of 50 countries and areas.

C. Different animals and the influence of humans on the natural world.

D. The hard work of more than 600 crew members.

2. What can we infer from the passage?

A. It took a lot of time and efforts to make the documentary.

B. People like to take a close look at animals.

C. The documentary is very popular in many countries and areas.

D. We humans can’t change the present condition of our planet.

3. What’s the purpose of the last paragraph?

A. To explain what our goal is in the future.  B. To call on more people to protect our planet.

C. To tell us the documentary is worth watching.  D. To tell us how the climate conditions influence animals.

4. Where is the text probably from?

A. A novel.  B. A travel journal. C. A storybook.  D. A newspaper.

第二部分　能力提升练

Ⅰ. 【语篇解读】本文是一篇说明文。文章主要讲述了保护野生动植物的重要性。

1. a　考查冠词。“in a/an + adj. + light”意为“从……的角度”，此处表示“从新的角度”，new的读音以辅音音素开头，故填a。

2. If 考查连词。句意：如果一个物种灭绝，它将永远消失。此空用连词连接逗号前后两句话，根据两句话的句意以及第一句使用了一般现在时，第二句使用了一般将来时可知，用if引导条件状语从句。

3. in　考查介词。句意：更重要的是，这将导致一系列野生动植物的灭绝，这可能造成无法预测的灾难。固定搭配result in意为“导致，造成”，符合句意。

4. it　考查代词。句意：另一方面，现代科学技术使我们有可能更多地了解野生动植物。此处用到“make + 宾语 + 形容词（宾语补足语）”结构，后面的不定式短语to learn...是真正宾语，所以用it作形式宾语。

5. have found 考查时态。句意：到目前为止，科学家们已经发现野生动植物具有未知的遗传密码，这可能会使人类在未来免遭严重疾病和自然灾害。此空所填内容作谓语，根据时间状语by now可知，此句用现在完成时，主语是复数，故填have found。

6. to free 考查非谓语动词。分析句子结构可知，定语从句已有谓语动词，此空用非谓语，turn out后跟动词不定式，故填to free。

7. natural　考查形容词。此空用形容词作名词disasters的定语，表示“自然的”，故填natural。

8. immediately　考查副词。句意：尽管人类已经污染了环境，威胁到许多野生物种的生存，但我们有必要在为时已晚之前立即保护野生动植物。此空用副词修饰动词短语protect wildlife，故填immediately。

9. existence　考查名词。此空用名词作threatened的宾语，且existence“存在，生存”是不可数名词，故填existence。

10. Learning/To learn 考查非谓语动词。句意：学会与所有野生动植物和谐相处是现代文明的一部分。分析句法结构可知，此句的谓语动词为is，故考虑用非谓语动词形式，该空用动名词或动词不定式均可。

Ⅱ. 【语篇解读】本文是一篇说明文。文章主要对纪录片《我们的星球》进行了相关介绍，它展示了不同的动物以及人类对自然界的影响。

1. C　细节理解题。根据第一段第二句“After that，a new documentary Our Planet shows different animals and the influence of humans on the natural world.”可知，这部新的纪录片是关于不同的动物以及人类对自然界的影响的。

2. A　细节理解题。根据第二段可知，这部纪录片的制作花费了大量时间和精力。

3. B　推理判断题。根据最后一段最后一句可知，最后一段旨在号召大家保护我们的星球。

4. D　推理判断题。通读全文可知，文章主要介绍了纪录片《我们的星球》，所以这篇文章可能是来自报纸的某个板块。

Ⅲ. 【语篇解读】这是一篇说明文。文章主要介绍了野外生存的三个基本需求——水、食物和遮蔽物。

1. A　根据上文“What would you do if you were left alone in the wild?”可知，条件是独自在野外，所以是在看似不可能的（impossible）条件下生存下来。impossible不可能的；unnecessary不必要的；unimportant不重要的；uncertain不确定的。

2. C　此处表示方式，意为“通过”，应用介词by。

3. D　根据上文Water is one of the few things necessary to make life可知，水是让生命继续（continue）下去的少数必需的东西之一。

4. B　根据上文but fresh water may be difficult to可知，此处指在野外难以找到（find）淡水。

5. A　根据下文by boiling it以及常识可知，水可以通过煮沸而变得干净（clean）。

6. D　根据下文of water，do not tire yourself too much可知，如果缺（shortage）水，不要让自己太累。storage储存；supply供应；donation捐赠；shortage短缺。

7. A　如果你迷路的时间较长，食物是另一种必需品。根据上文three basic needs：water，food and shelter可知，此处表示三者中的“另一个”，应用another。

8. C　根据下文by eating animals easy to catch可知，有些人吃容易抓的动物来充饥（hunger）。thirst口渴；tiredness疲惫；hunger饥饿；scare恐惧。

9. D　根据上下文语境可知，不应该吃植物和可以吃动物之间为转折关系，应用however。moreover此外；therefore因此；besides此外；however然而。

10. A　根据上文可知，此处指在野外坚果很容易识别（recognise）。

11. C　根据第一段中three basic needs：water，food and shelter可知，此处指抵御（protection）极端温度，短语protection from表示“抵御……”。prevention预防；observation观察；protection保护；safety安全。

12. A　根据上文In heavy snow可知，大雪天需要的是保暖（warm）措施。

13. D　根据下文a small cave at the base of a thick evergreen tree可知，此处指在一棵茂密的常青树的底部挖（create建造）一个小洞穴。

14. B　当天气非常热的时候，你可以在一棵茂密的常青树的底部挖一个小洞穴，用树枝来保持洞穴凉爽。根据上下文语境可知，此处为并列关系，应用连词and。

15. D　想出一个计划，不要因为担心而浪费时间和精力。根据下文with a plan可知，此处指想出计划，应用短语come up with。come into进入；come out出版；come across遇到；come up with提出，想出。
