Question

【题目】 Spring is here. Did you plant trees on Tree-Planting Day? Everyone knows that climate change is a serious problem these days. People have a lot of work to do in order to prevent it. One of the best ways is to plant more trees.

According to a study by NASA, the Earth’s green leaf area has increased by 5 percent, or over 5 million square kilometers since 2000. China is responsible for 25 percent of the increase. That’s about one square of the size of the whole Amazon rainforest.

Over the past twenty years, China has made great efforts to green the land in order to fight soil erosion (水土流失) and air pollution. It is one of the most successful countries in greening the desert.

For example since 1962, China had been planting trees in Saihanba in Hebei province. It was once a barren(贫瘠) area. After overcoming many difficulties, foresters have turned the area into China’s largest man-made forest. Another example is the Kubuqi Desert, which is near the Yellow River in Inner Mongolia. It was once the source(来源) of sandstorms in Beijing. But now, about one third of the Kubuqi Desert is covered with trees, and sandstorms are less common. Mu Us Desert was also known for its sandstorms many years ago. But now, one-quarter of the desert has been turned into forest.

In a word, planting trees is really important to us. Let’s take part in planting trees to make our earth greener and more beautiful.

【1】The reason why China makes great efforts to green the land is to _____

A. prevent climate changeB. plant more trees

C. reduce water pollutionD. stop the soil from being washed away

【2】Which of the following is TRUE according to the passage?

A. China succeeds in greening the desert

B. Planting tree is the best way to prevent the climate change

C. The green leaf area of China has increased by 0.25 million square kilometers since 2000.

D. Mu Us Desert cause the sandstorms in Beijing

【3】It is _______ for foresters to turn Saihanba into the forest

A. dangerousB. excitingC. difficultD. impossible

Answer 1

【答案】

【1】D

【2】A

【3】C

【解析】

本文主要谈论植树是防止气候变化最好的方法之一，以及中国在治理水土流失和空气污染取得了成就。根据美国国家航空航天局的一项研究，自2000年以来，地球的绿叶面积增加了超过500万平方公里。其中中国占了25%。中国是沙漠绿化最成功的国家之一。像在河北塞罕坝种树；绿化库布其沙漠和毛乌素沙漠。最好号召我们一起种树，让我们的地球更绿更美。

【1】题意：中国大力绿化国土的原因是__________。考查细节理解。A. prevent climate change防止气候变化；B. plant more trees种植更多的树木；C. reduce water pollution减少水污染；D. stop the soil from being washed away防止土壤被冲走。根据第3段第1句Over the past twenty years, China has made great efforts to green the land in order to fight soil erosion (水土流失) and air pollution.（在过去的二十年中，中国为防治水土流失和空气污染，大力开展土地绿化工作。）可知选D。

【2】题意：根据文章，下列哪一项是正确的？考查细节理解判断。A. China succeeds in greening the desert中国成功地绿化了沙漠；B. Planting tree is the best way to prevent the climate change植树是防止气候变化的最好方法；C. The green leaf area of China has increased by 0.25 million square kilometers since 2000. 2000年以来，我国绿叶面积增加了25万平方公里；D. Mu Us Desert cause the sandstorms in Beijing毛乌素沙漠导致北京沙尘暴。根据第1段最后一句One of the best ways is to plant more trees.（最好的办法之一就是种更多的树。）可知植树是防止气候变化的最好方法之一，B错误；根据第2段第1和2句According to a study by NASA, the Earth’s green leaf area has increased by 5 percent, or over 5 million square kilometers since 2000. China is responsible for 25 percent of the increase.（根据美国宇航局的一项研究，自2000年以来，地球的绿叶面积增加了5%，即超过500万平方公里。其中中国占了25%由。）可知中国绿叶面积500*25%=125万平方公里，C错误；根据第4段第4和5句Another example is the Kubuqi Desert, which is near the Yellow River in Inner Mongolia. It was once the source(来源) of sandstorms in Beijing.（另一个例子是内蒙古靠近黄河的库布其沙漠。它曾是北京沙尘暴的源头。）可知D错误。根据第3段最后一句It is one of the most successful countries in greening the desert.（它是沙漠绿化最成功的国家之一。）和第4段列举的例子（布其沙漠和毛乌素沙漠），可知中国成功地绿化了沙漠；A是正确的；选A。

【3】题意：把塞罕坝变成森林对林业工作者来说是_______________。考查细节理解。A. dangerous危险；B. exciting刺激；C. difficult困难；D. impossible不可能。根据第4段第1句For example since 1962, China had been planting trees in Saihanba in Hebei province. It was once a barren(贫瘠) area. After overcoming many difficulties, foresters have turned the area into China’s largest man-made forest.（例如，1962年以来，中国一直在河北塞罕坝种树。它曾经是一个贫瘠的地区。在克服了许多困难之后，林业工作者把这个地区变成了中国最大的人工林。）可知“把塞罕坝变成森林对林业工作者来说是困难的”；故选C。
