【題目】Qian Xuesen, the father of China’s space program, is generally considered as the greatest s________ in China.

【答案】scientist

【解析】

句意：錢學(xué)森，中國太空計(jì)劃之父，被公認(rèn)為是中國最偉大的科學(xué)家。

句中greatest是形容詞great的最高級(jí)形式，所以此處使用名詞；根據(jù)句中“the father of China’s space program”可知，此處使用scientist；scientist是名詞，意為“科學(xué)家”，用在此處表示“錢學(xué)森被公認(rèn)為是中國最偉大的科學(xué)家”。故填scientist。

【題目】 People in Western countries are eating less meat these days, whether for their health or because they want to protect animals. But now they have another reason.

Eating less meat can help to prevent climate change, according to a recent study published in Nature.

Raising livestock (家畜) is bad for the environment. When animals like cows digest (消化) food, their stomachs make greenhouse gases, which are a major cause of global warming. Seventeen percent of greenhouse gas emissions (排放) come from livestock farming, The New York Times reported.

In addition, to raise these livestock, people have to cut down forests and turn them into farms. Forests play a key role in fighting global warming because they absorb greenhouse gases.

Eating less meat according to certain guidelines could cut global food-related emissions by nearly a third by 2050, the study found. Keeping a vegetarian diet in the long term could bring down emissions by 63 percent.

But eating less meat won’t be easy. According to the study, people in Western countries will need to eat 90 percent less meat than they do now in order to have an impact (影響) on our climate. Scientists are now trying to find new foods to replace meat.

Some say that insects could help. A 2013 UN report said that eating insects is healthier and better for the environment. They produce 75 percent less greenhouse gases than livestock.

Some experts are creating lab-grown meat. They make meat in a lab using livestock cells (細(xì)胞). In March, US company JUST said people in the US might be able to buy its lab-grown meat by the end of this year

【1】How much less meat should people eat to influence the climate?

A.63 percent.B.70 percent.C.75 percent.D.90 percent.

【2】Eating less meat can help protect the environment because _____.

A.there will be more animal-related waste

B.less livestock means less greenhouse gas emissions

C.animals are an important part of the environment

D.people will plant more trees around their houses

【3】According to the story, eating less meat can help us _____.

a. stay healthy b. reduce waste c. protect animals d. slow down climate change

A.a;b;cB.b;c;dC.a;b;dD.a;c;d

【4】What is the main idea of the story?

A.Why Westerners eat less meat these days.

B.What people will eat in the future.

C.How eating less meat influences the environment.

D.What the major cause of global warming is.
