Question

    Over the last two decades (十年), the Earth has seen an increase in vegetation (植被) and China and India are leading the increase in greening on land. The result comes mostly from tree planting programs in China and intensive agriculture(集约农业) in both countries.

Researchers from Boston University found that global green area has increased by 5% since the early 2000s, an area equal to the size of Amazon rainforest. Among the increased area, China and India contribute to about 33%, especially China, with 25% itself. China’s great contribution came mostly from its programs to protect and expand forests, which is about 42%. These programs were developed in an effort to reduce the effect of desertification, air pollution and climate change.

Another 32% of the greening change in China, and 82% in India, resulted from intensive agriculture of food crops. The land area used to grow crops in China and India has not changed much since the early 2000s. Yet both countries have greatly increased the total green area and food production in order to feed large populations. The lead author Chi Chen of Boston University said,

“That is a surprising finding, since it is generally believed that land degradation(退化) in populous countries is usually more serious.”

Rama Nemani, a research scientist at NASA’s Ames Research Center, saw a positive message in the new findings. “Once people realize there is a problem, they tend to fix it,” However, the researchers rang bells as well. They pointed out that the gain did not necessarily fill up the loss of natural vegetation in tropical regions like Brazil and Indonesia.

1.What’s the first paragraph mainly about?

A.The earth is becoming a green land.

B.China and India are forest countries.

C.China and India matter in greening the Earth.

D.China and India develop intensive agriculture well.

2.Why is Amazon rainforest mentioned in Paragraph 2?

A.To show its importance to the planet.

B.To call on people to protect rainforests.

C.To clearly show the increased green area.

D.To be evidence of the lost natural vegetation.

3.What benefits can China’s tree planting programs bring?

① Reducing air pollution.   

② Increasing rich land for crops.

③ Helping with climate control.   

④ Controlling the desertification.

A.①②③ B.①③④

C.①②④ D.②③④

4.What can we infer from the last paragraph?

A.Brazil and Indonesia do not protect their forests.

B.The findings discouraged belief of a green world.

C.Humans are creative enough to solve all problems.

D.More efforts are needed to protect natural vegetation.

5.Where does the text probably come from?

A.A newspaper. B.A travel brochure.

C.An interview. D.A geography textbook.

【解析】

本文是新闻报道。研究指出，印度和中国正在引领全球的绿色行动。中国和印度引领了陆地绿化的增加，但与此同时研究人员也指出，这种增长并不一定能弥补巴西和印度尼西亚等热带地区自然植被的丧失，因此需要更多的努力来保护自然植被。

1.段落大意题。根据第一段“Over the last two decades (十年), the Earth has seen an increase in vegetation (植被) and China and India are leading the increase in greening on land. The result comes mostly from tree planting programs in China and intensive agriculture(集约农业) in both countries.”可知，在过去的二十年中，地球的植被增加了，中国和印度引领了陆地绿化的增加。这个结果主要来自于中国的植树计划和两国的集约农业。即第一段主要讲的是中国和印度在增加地球绿地方面发挥着重要作用。故选C。

2.推理判断题。根据第二段中的“Researchers from Boston University found that global green area has increased by 5% since the early 2000s, an area equal to the size of Amazon rainforest.”可知，波士顿大学的研究人员发现，自2000年以来，全球绿化面积增加了5％，该面积等于亚马逊雨林的面积。因此第2段中提到亚马逊雨林是为了清楚显示增加的绿地面积。故选C。

3.细节理解题。根据第二段中的“These programs were developed in an effort to reduce the effect of desertification, air pollution and climate change.”可知，制定这些计划是为了减少荒漠化，空气污染和气候变化的影响。即中国的植树计划可以带来很多好处：减少空气污染、促进气候控制和控制荒漠化。故选B。

4.推理判断题。根据最后一段中的“Rama Nemani, a research scientist at NASA’s Ames Research Center, saw a positive message in the new findings. “Once people realize there is a problem, they tend to fix it,” However, the researchers rang bells as well. They pointed out that the gain did not necessarily fill up the loss of natural vegetation in tropical regions like Brazil and Indonesia.”可知，NASA艾姆斯研究中心的科学家Rama Nemani在新发现中看到了积极的信息。 “一旦人们意识到存在问题，他们就会倾向于解决它。”然而，研究人员也大声疾呼。他们指出，这种增长并不一定能弥补巴西和印度尼西亚等热带地区自然植被的丧失。即从最后一段我们可以推断出需要更多的努力来保护自然植被。故选D。

5.推理判断题。通读全文可知，人们普遍认为，人口稠密国家的土地退化通常更为严重。但是中国和印度引领了陆地绿化的增加。结果主要来自中国的植树计划和两国的集约农业。但与此同时研究人员也指出，这种增长并不一定能弥补巴西和印度尼西亚等热带地区自然植被的丧失，因此需要更多的努力来保护自然植被。因此这样的内容可能来自于报纸的科学栏目。故选A。
