【題目】 Do you know why different animals or pests (害蟲) have their special colors? Colors in them seem to be used mainly to protect themselves.

Some birds like eating insects, but birds cannot easily catch insects. Why? It is because insects change their colors together with the change of the colors of crops. When crops are green, insects look green. But as the harvest time comes, insects change to the same brown color as crops have. Some other insects with different colors from plants are easily found and eaten by others. So they have to hide themselves for lives and appear only at night.

If you study the animal life, you’ll find the main use of colors is protecting them. Bears, lions and other animals move quietly through forests. They cannot be seen by hunters. This is because they have the colors much like the trees.

Have you ever noticed an even strange animal? A kind of fish in the sea can send out a kind of very black liquid (液體) when it faces danger. While the liquid spreads over, the fish itself cannot be found. And it quickly swims away. So it has lived up to now though it isn’t strong at all.

【1】Why do some animals have different colors? （不超過 10 個(gè)詞）

___________________________________________________________________

【2】When the harvest time comes, which color do some insects change to? （不超過 10 個(gè)詞）

___________________________________________________________________

【3】What can the fish do in the last paragraph when it faces danger? （不超過 15 個(gè)詞）

___________________________________________________________________

【答案】

【1】To protect themselves.

【2】They change to the same brown color as crops have.

【3】They can send out a kind of very black liquid.

【解析】

這篇短文主要講述了不同的動(dòng)物和害蟲都會(huì)有著和環(huán)境相似的顏色，這些顏色主要是用來保持他們自己不受到傷害。

【1】題干“為什么有些動(dòng)物有不同的顏色？”根據(jù)文中“Colors in them seem to be used mainly to protect themselves.”可知，這些顏色是用來保護(hù)他們自己的。故答案為To protect themselves.

【2】題干“當(dāng)收獲的時(shí)候，一些昆蟲會(huì)變成什么顏色？”根據(jù)文中“But as the harvest time comes, insects change to the same brown color as crops have.”可知，它們會(huì)變成和莊稼一樣的棕色。故答案為They change to the same brown color as crops have.

【3】題干“最后一段，當(dāng)魚面臨危險(xiǎn)時(shí)，能做什么？”根據(jù)文中“A kind of fish in the sea can send out a kind of very black liquid (液體) when it faces danger.”可知，它們能發(fā)出一種非常黑的液體。故答案為They can send out a kind of very black liquid.

【題目】 Chinese A-level has overtaken German for the first time, as it becomes the UK's third most popular language.

This year 3,334 students took Chinese A-level, compared to 3,058 taking German. While entries（報(bào)名者）for Chinese have increased by 8.6 percent since last year, the number of German entries has dropped by 16.5 percent. French remains the most popular modern language followed by Spanish（西班牙語），but both have seen a fall in entries compared to last year by eight and four percent separately.

Barnaby Lenon, expert of the independent Schools Council (ISC), said that the teachers used to tell pupils "It will really help your future if you learn German", but this is no longer the case.

In the 1960s, the 1970s and even the 1990s, pupils were strongly encouraged to study German because of the importance of the German economy（經(jīng)濟(jì)）．Although it is still strong, that argument has disappeared gradually, and China has become known in the last 25 years for the fastest growing economy in the world.”

Mr. Lenon, a former headmaster at Harrow School, said the increase in Chinese A-level is partly driven by private schools. Many of them have put more money in the subject in recent years. "It is not the case that a large number of state schools are now teaching Chinese A-level. They are not," he said. Many of the entries will be Chinese native speakers, adding that independent schools have attracted（吸引）"large numbers" of Chinese pupils in recent years.

Mark Herbert, director of schools and skills at the British Council, welcomed the rise in Chinese A-level entries. Our research shows that Mandarin（漢語）will be one of the most important languages for the UK's future and position-but we mustn't give no attention to Spanish, French and German which will still be important post-Brexit（脫歐后）．

Nick Gibb, the school minister, said, "It has never been more important for young people to learn a foreign language than now."

【1】The underlined word overtake in Paragraph 1 means _________．

A.catch up and begin to do better thanB.be strongly against

C.come suddenly and unexpectedly toD.be in control of

【2】Which language has the second largest number of entries in the UK this year?

A.Chinese.B.German.C.French.D.Spanish.

【3】Students were encouraged to learn German in _________because Germany's economy was in good condition.

A.the late ninetieth centuryB.the early twentieth century

C.the late twentieth centuryD.the early twenty-first century

【4】According to Mr. Lenon, the rise in Chinese A-level is, in some ways, caused by _________．

A.private schoolsB.state schoolsC.Chinese schoolsD.German schools

【5】What can we learn from Mark Herbert's speech in Paragraph 6?

A.He is against learning Chinese.

B.It's difficult to learn Chinese well.

C.Spanish, French and German are easy to learn.

D.Britain should take all kinds of foreign languages seriously.

【題目】 Fresh green grass, hundreds of colorful wild flowers, water running into little pools, birds making their homes in boxes, the 9,500-square-meter Augustenborg Botanical Garden may look just like any other well-organized park, but there’s a difference. It lies on the roofs (屋頂) of industrial and office buildings in the city of Malmo in Sweden.

Green roofs are not a new invention. And now they are getting popular again. The common roofs of a modern city have endless black surfaces with no life or water. Perhaps that’s why a garden on a roof becomes such a perfect choice for more and more people.

Green roofs are not just pretty. They also help to moderate the city temperature. The high temperatures on common roofs in the summer can make top floor flats uncomfortably hot. What is more, they play a part in making the cities hotter than the countryside around them, causing the “urban heat-island effect”. On a green roof, however, with its plants and water, temperatures change only a little, as they do in a park. Rooftops covered with plants help keep buildings cool. Green roofs take in rain water and protect the city drainage (排水) system. They can reduce water runoff into streets and storm water systems. This can greatly cut the costs of heating and cooling in the building below.

Also, _______. Small animals and birds can make their homes on it. Thanks to this, the city may become part of nature, rather than something completely separate from it. Though they won’t directly replace ground environments, they’re perfect for attracting birds and other wildlife to create a eco-friendly habitat (棲息地).

A green roof helps to improve the overall air quality, too. According to a study, green roofs help reduce (減少) up to:

37% of sulfur dioxide

21% of nitrous acid

0.2kg of dust particles / square meter each year

While the cost of building such a roof can still be higher, it can be cheaper in the long term as a result of energy savings. And wouldn’t it be wonderful to be able to walk out into a garden high above the city’s noise and traffic, whether you’re at school or in an office or just at home in a ten-floor block?

【1】With the example of Augustenborg Botanical Garden, the writer wants to explain ________.

A.how wildlife is protectedB.what a green roof is like

C.how to organize a good parkD.what to do with a spare roof

【2】The word “moderate” in Paragraph 3 probably means “________”.

A.raiseB.checkC.recordD.control

【3】Which of the following is the best sentence to fill in the blank in Paragraph 4?

A.a green roof is aliveB.a green roof protects animals

C.a green roof is perfectD.a green roof helps the environment
