Unit 3 单元主题语篇训练

Ⅰ.阅读理解

A

Coral reefs (珊瑚礁) are an integral part of sea life and sustain it by providing shelter and habitat to various organisms. They also supply and recycle nutrients as well as enable a growing fish population, along with other species, for a healthy and diverse ecosystem. However, the rise in average water temperatures due to climate change has resulted in more frequent and long­time “coral bleaching (珊瑚白化)” events that damage their health, causing fish and other sea species to abandon them.

In order to restore this delicate ecosystem, scientists from the U. K. and Australia conducted a study that involved using loudspeakers underwater near damaged coral reefs to make them sound healthy and attract fish, potentially kick­starting the natural recovery process of coral reefs and their dependent life forms. The location for this experiment was the Great Barrier Reef in the Coral Sea, found alongside the east coast of Queensland, Australia. The site is noted to have the largest coral reef system in the world.

“Healthy coral reefs are remarkably noisy places — the crackle of snapping shrimp and the whoops and grunts of fish. Young fish concentrate on these sounds when they're looking for a place to settle，” said Steve Simpson, study co­author and a professor at the University of Exeter, U. K.

By using loudspeakers to copy such sounds, parts of dead coral reefs were found to attract twice as many fish, compared to places where no sounds were played. “These returning fish are crucial for coral reefs to function as healthy ecosystems. Boosting fish population in this way could help to kick­start natural recovery processes, preventing the damage we're seeing on many coral reefs around the world，” said lead author, Tim Gordon.

语篇解读：由于海水温度的上升，深海珊瑚的生态遭到破坏。科学家通过实验研究发现，在珊瑚礁旁边放置扬声器以吸引海洋生物对于恢复珊瑚的生态卓有成效。

1．What causes the phenomenon of coral bleaching?

A．Diverse species.　　　　 B．Noise pollution.

C．Fishing industry.  D．Climbing temperatures.

解析：选D　细节理解题。根据第一段第三句可知，是气候变化所引起的海水温度的上升导致了这种白化现象。故选D项。

2．What approach is introduced to recover the coral reefs?

A．Removing damaged coral reefs.

B．Using loudspeakers to keep fish away.

C．Building new homes for sea species.

D．Playing certain sounds to attract fish.

解析：选D　细节理解题。根据第二段第一句可知，为恢复珊瑚生态，科学家在遭破坏的珊瑚附近放置扬声器，以吸引鱼类。即通过播放声音来吸引鱼类。故选D项。

3．Why are Steve Simpson's words quoted?

A．To provide some findings of the study.

B．To show the progress of the experiment.

C．To explain reasons for the new approach.

D．To give another solution to the problem.

解析：选C　细节理解题。根据前两段内容可知，鱼儿会离开不健康的、遭到破坏的珊瑚。为了吸引鱼类，科学家们在这些珊瑚附近放置扬声器。再结合第三段第一句可知，健康的珊瑚礁是非常热闹的地方，各种海洋生物很多。由此可推知，此处引用这位教授的话是为了解释在受损珊瑚礁旁边放置扬声器这一新方法的原因。故选C项。

4．What can we infer from the last paragraph?

A．The attempts are in vain.

B．Natural recovery is impossible.

C．Initial success has been achieved.

D．The coral reefs have returned to normal.

解析：选C　推理判断题。根据最后一段第一句可知，通过用扬声器复制一些声音，部分死亡的珊瑚礁吸引了更多的鱼类，由此可推知，珊瑚生态保护已经初见成效。故选C项。

B

I'm on the phone with a frustrated customer, and a note appears on my computer screen: You are speaking slower than usual. Speed up. I do, and the message disappears, only to be replaced with another: Continuous Speaking — Finish your thought.

This is Cogito, an artificial intelligence program designed to help customer service workers communicate more clearly, empathize (产生共鸣) with frustrated callers, and improve their overall performance. Cogito listens to the tone, pitch, word frequency and other factors in customer service conversations. When it detects something wrong — an irritated customer, a call center agent taking too long to respond — it displays a note on the agent's computer telling them how to improve.

For anyone who's spent hours of their lives stuck on the phone with an unhelpful or very rude customer service agent, Cogito may seem like a godsend. And some customer service agents using the software generally say they find it helpful. One employee says that Cogito helped her cut her average call time nearly in half, while another says it helped her speaking slow down.

Cogito has been launched to more than sixty call centers across the U．S. over the past year. The company behind the software, Cogito Inc., has raised more than  $70 million.“We were 45 people a year ago，” says Cogito CEO Josh Feast, whose company now has 150 employees. At MetLife, managers say that the program improved customer satisfaction by 13%, and helped agents (who take an average of 700 calls a week) to have more “human” conversations.

Such software as Cogito is unlikely to stop at the meeting room. But like other enterprise software, it could soon spread well beyond call centers and other offices and into our daily lives.

语篇解读：本文是一篇科研报道。一家公司发明了一款人工智能软件，可以通过电脑分析客户服务人员和顾客的语速、语调以及说话人的情绪，适时给出建议，提高客服人员的沟通能力。

5．What's the purpose of Cogito program?

A．To speed up customer service workers' speaking.

B．To store the conversations between customers and agents.

C．To improve customer service agents' communication with callers.

D．To complain of frustrated callers.

解析：选C　细节理解题。根据第二段第一句可知，这款人工智能程序的目的在于帮助客服人员更清晰地沟通，与恼火的来电者产生共鸣，从而提高他们的整体表现。注意题干、正确选项与原文中一些词汇的呼应现象。题干中的purpose与原文的designed相呼应。

6．What can we infer about Cogito in Paragraph 4?

A．Cogito has been used by sixty call centers in the world.

B．The company behind the software benefits a lot from Cogito.

C．Josh Feast designed Cogito with the help of employees.

D．Customers weren't satisfied with MetLife's service without Cogito.

解析：选B　推理判断题。根据第四段第二句“The company behind the software, Cogito Inc., has raised more than $70 million.”可知，发明这个软件的公司赚了七千多万美元，因此可推断出这个软件给公司带来了很大的利润。

7．What's the future of Cogito according to the text?

A．It'll be part of our normal day­to­day life.

B．It'll spread into other offices.

C．It'll tell humans what to do.

D．It'll replace customer service agents.

解析：选A　细节理解题。根据最后一段中的“... it could soon spread well beyond call centers and other offices and into our daily lives.”可推出B 项错误，A项切题。 根据文章第一段可知C选项的表述已经成为现实，故C项不切题，D项的内容在文章中没有任何相关信息作为依据，属于无中生有。

8．Where is the text most likely from?

A．A novel.　　　　　　 B．A brochure.

C．A guidebook.  D．A magazine.

解析：选D　文章出处题。全文围绕人工智能软件Cogito来展开说明，介绍了这款智能软件的研发目的以及工作原理，并从各个不同的角度说明了它带来的好处，最后展望了Cogito的发展前景，由此可推断出本文讨论的是和科学技术相关的话题，最有可能出现在杂志上。

Ⅱ.短文改错

This morning I happened to meet a foreigner when I was taking walk in the park. It was a good chance for me to practise my spoken English, but I went up to him, introduced himself in English and expressed my wish to have a talk with him. In my surprise, he just stared at me, looking puzzling.I thought I had not made myself understand, so I repeated again what I had said. But he just said anything that I didn't understand.I suddenly realize he was not an English speaker! Not all foreigner speak English.

答案：第一句：taking后加a

第二句：but→so; himself→myself

第三句：In→To; puzzling→puzzled

第四句：understand→understood; 去掉again

第五句：anything→something

第六句：realize→realized

第七句：foreigner→foreigners

参考范文：

Dear Tom，

Welcome to China! You can't imagine how delighted I feel when I know that you will be traveling in China by CRH. I'm honored to have the chance to introduce CRH to you.

As you know, China is developing at a high speed. CRH has developed rapidly these years due to China's vast area and large population. In many cities, CRH stations are much closer to the living areas, which makes it more convenient to transport people and goods. Compared to buses and planes, people prefer CRH because of its high speed, great comfort and safety. Thus, CRH is the best means of transportation in China. It's wise of you to choose CRH when you travel in China. Additionally, booking a ticket online in advance can save you much time and energy.

Hope you will enjoy your trip by CRH.

Yours faithfully，

Li Hua
