Question

【題目】April 22 is Earth Day. Everyone on Earth should care about and protect the earth!

The earth has warmed by about 1°F (華氏度) over the past 100 years, but why and how? Well, scientists are not quite sure. Maybe the earth gets warmer and warmer on its own. But many scientists say that people are doing many things which make the earth warmer. First, greenhouse effect (溫室效應(yīng)) is a very important reason for the change of the earth. People give out too much energy into the air every year. It makes the earth warmer. Climate (氣候) change is another important reason. Sometimes it becomes too hot and sometimes too cold. Sometimes there is too much rain and sometimes too little. The change of the climate makes the earth warmer. In turn, the warmth of the earth changes the climate, too.

When the earth becomes warmer, there may be more rain and a rise in sea level. It will affect the growth of plants, animals and people. On a Pacific island, 100 people have to move to higher ground because the sea is rising. These people can no longer live on the coast. Before that, two islands without people went underwater in 1999. Scientists say that the seas can rise by nearly one meter by 2100.

People can affect the earth's air, land and water. As for us, we can do many things to protect the earth. For example, we can use fridges less. We can tell more people about protecting the earth.

【1】Earth Day is probably set for people to ______.

A.learn more about the earth

B.make full use of the earth

C.take better care of the earth.

D.study the warmth of the earth

【2】Greenhouse effect comes from______.

A.sea rising B.climate change

C.nature's unbalance D.people's activity

【3】According to the passage, _______ many affect each other.

A. animals and island

B. climate and the warmth of the earth

C. fridges and animals

D. sea level and the growth of plants

【4】We can infer (推斷) from the passage that the reasons for the warmer earth are______ now.

A.not very clear B.completely secret

C.well known D.not given yet

【5】The passage mainly tells us that ______.

A.there is more rain now

B.we should protect the earth

C.we must stop pollution

D.sea level is getting higher

【解析】

試題分析：本文是一篇與地球變暖相關(guān)的短文。短文分析了地球變暖的原因、造成的影響，并號召人們保護環(huán)境。

【1】C推理判斷題。題意：地球日的設(shè)立可能是為了人們做什么的？A.learn more about the earth更多地了解地球；B.make full use of the earth 充分利用地球；C.take better care of the earth. 更好地照顧地球；D.study the warmth of the earth 了解地球變暖。根據(jù)短文內(nèi)容，地球日的設(shè)立是為了幫助人們更多地了解和保護地球環(huán)境。故選C

【2】D細節(jié)理解題。題意：溫室效應(yīng)來自什么？A.sea rising海洋的上升；B.climate change氣候的改變；C.nature's unbalance自然的不平衡；D.people's activity人們的活動。由第二段里的：But many scientists say that people are doing many things which make the earth warmer.可知，許多科學(xué)家認為是人類的活動使地球變暖了。故選D。

【3】B推理判斷題。題意：根據(jù)短文內(nèi)容，什么互相影響？A. animals and island動物和島嶼；B. climate and the warmth of the earth氣候和地球的溫度；C. fridges and animals冰箱與動物；D. sea level and the growth of plants海平面與植物的生長。由第二段最后的句子：The change of the climate makes the earth warmer. In turn, the warmth of the earth changes the climate, too.可知氣候的變化使地球變暖，而地球變暖也改變氣候。故選B。

【4】A細節(jié)理解題。題意：根據(jù)短文內(nèi)容，我們可以推斷出地球變暖的原因現(xiàn)在怎樣了？A.not very clear不是很清楚；B.completely secret完全是秘密；C.well known眾所周知；D.not given yet還沒有給出。由第二段里的： Well, scientists are not quite sure. Maybe the earth gets warmer and warmer on its own. 可知，科學(xué)家還不很清楚地球變暖的原因。故選A。
