【題目】—It's very important for us to keep ________.

—You are right. We should learn how to protect ourselves when we're in trouble.

A.rapidB.safeC.luckyD.social

【答案】B

【解析】

句意：——對我們來說保證安全是很重要的。——你是對的。當(dāng)我們遇到麻煩時，我們應(yīng)該學(xué)會保護(hù)自己。

考查形容詞辨析。rapid迅速的；safe安全的；lucky幸運(yùn)的；social社會的。分析句意并結(jié)合“We should learn how to protect ourselves when we're in trouble.”可知，此處強(qiáng)調(diào)當(dāng)我們遇到麻煩時，我們應(yīng)該學(xué)會保護(hù)自己，即保證安全。故選B。

【題目】 Many things can be shared these days, such as bikes, cars and chargers(充電寶). A “sharing bookstore” also came out last year.

Sanxiaokou Xinhua Bookstore, the world’s first sharing bookstore, opened on July 16 in Hefei, Anhui province, according to China News. It sells books as normal bookstores. But at the same time, it allows readers to take books home for free to read after paying a 99 yuan deposit(押金). They can borrow two books in 10 days by scanning a QR code(掃描二維碼) on the book.

The bookstore is quite popular among the cily’s readers. By Aug 26, more than 100,000 books had been borrowed. The number of visitors to the bookstores has also grown by 50 percent. The bookstore is going to open nine more stores in other places of the city.

But some people question that these sharing bookstores are just like a library.

“Although the two both rent books, sharing bookstores have more kinds of books," Xu Xinwei, the store’s deputy manager(副店長)，told China News. “We also renew(更新) our book selection more often than libraries.”

【題目】 Many people say dolphins are very itelligent. They seem to be able to think, understand, and learn things quickly. But are they smart like humans or are they more like cats or dogs? Dolphins use their brains differently from people. But scientists say dolphin intelligence and human intelligence are similar in some ways. How?

Like humans, every dolphin has its own name. The name is a special whistle. Each dolphin chooses a specific whistle for itself, usually by its first birthday. Actually, scientists think dolphins, like people, “talk” to each other about a lot of things, such as their age, their feelings, or finding food. And, like humans, dolphins use a system of sounds and body language to communicate. But understanding their conversations is not easy for humans. No one speaks “dolphin” yet, but some scientists are trying to learn.

Dolphins are also social animals. They live in groups, and they often join others from different groups to play games and have fun—just like people. In fact, playing together is something only intelligent animals do.

Dolphins and humans are similar in another way: both species make plans to get something they want. In the seas of southern Brazil, for example, dolphins use an interesting strategy to get food. When fish are near a boat, dolphins show signs to the fishermen to put their nets in the water. Using this method, the men can catch a lot of fish. What is the advantage for the dolphins in doing so? They get to eat some of the fish that escape from the net.
