Question

【題目】 Ladies and gentlemen, I returned to this year in a time machine. In the year 2500, we are able to travel through time to any year in the history of the earth. This year is your last chance to change your lifestyle to save the earth.

Beginning in the middle of the 20th century, a few people were worried about polluting the earth’s water and air, but most people did not change their way of life. Instead, they continued to pour dangerous chemicals and other waste into lakes and seas, to drive more and more cars and trucks, and to cut down trees.

By the year 2200, the earth’s water was completely polluted. People could no longer drink water, and they had to use other types of liquids.

So, by the year 2300, there were so many people that food became scarce. There was no water to grow food and all of the fish in the lakes and seas died because of the pollution. Terrible wars broke out between the rich and the poor. Scientists were working very hard to find another planet in space where humans could live.

By the year 2400, the air was too polluted for humans to breathe. So we had to leave the earth. Where did we go? Nowhere. The scientists did not find another safe planet, so now we must travel around the universe in our spaceships. We are still looking for a place to call our home.

So, it is up to change history. There is still hope. You must change your lifestyle now, before it is too late.

【解析】

文章大意：本文主要以擬人的手法講述了環(huán)境污染的嚴(yán)重事實(shí)，作者通過時(shí)間隧道從2500年穿越回到了20到25世紀(jì)的不同時(shí)代，并描述了各個(gè)不同時(shí)代的污染的嚴(yán)重性，提醒人類保護(hù)環(huán)境，愛護(hù)人類自己．

【1】詞義猜測題。根據(jù)本句內(nèi)容“So by the year 2300， there were so many people that food became scarce．”可知，本句中包含一短語so…that…，意為截止到2300年，地球上的人類是如此之多以致于食物變得太少．再加上下一句“There was no water to grow food”，可知食物應(yīng)該是不夠人類吃的，可知，“scarce”是“缺少的”意思，故答案為B。

【2】細(xì)節(jié)理解題。根據(jù)短文第二段“a few people were worried about polluting the earth's water and air， but most people did not change their way of life．”內(nèi)容可知，本段主要涉及到了空氣質(zhì)量、水資源和人類的生活方式，唯獨(dú)沒有提到食物方面的問題，故答案為B。

【3】細(xì)節(jié)理解題。根據(jù)短文第四段“By the year 2400， the air was too polluted for humans to breathe． So we had to leave the earth． ”可知，到了2400年，空氣被污染得無法呼吸。所以我們不得不離開地球。故答案為C。

【4】細(xì)節(jié)理解題。根據(jù)短文第二段“Beginning in the middle of the 20th century， a few people were worried about polluting the earth's water and air， but most people did not change their way of life．”可知，從20世紀(jì)中葉開始，有少數(shù)人擔(dān)心污染地球的水和空氣，但大多數(shù)人并沒有改變他們的生活方式。也就是： 在20世紀(jì)中葉，只有少數(shù)人改變了他們的生活方式。A是對(duì)的。根據(jù)文中“By the year 2200, the earth’s water was completely polluted” 到2200年，地球上的水被完全污染了�？芍�，B. There wasn’t enough food for people to eat by the year 2200.是錯(cuò)誤的；根據(jù)文中“So, by the year 2300, there were so many people that food became scarce.” 所以，到了2300年，人口太多，食物變得稀缺�？芍�，C. All the animals died because of pollution by the year 2300.是錯(cuò)誤的，故答案為A。

【5】主旨大意題�？v觀全文內(nèi)容可知本文主要描述的就是人類的污染環(huán)境極其嚴(yán)重，已經(jīng)嚴(yán)重威脅人類的生存，到了非停止不可的地步了，否則我們不得不離開地球。所以C項(xiàng)Change or Leave“改變或離開”作為文章標(biāo)題比較合適，故答案為C。
