【答案】

【小題1】① bad ②died

【小題3】因此我們必須采取行動(dòng)阻止人們污染(我們的)地球。

【小題4】上升

【小題5】Cars and buses.

【解析】

試題分析：本文敘述了自從地球上有人類以來(lái)，人們對(duì)環(huán)境的影響很大，一些森林和農(nóng)場(chǎng)變成了沙漠，一些城市由于海平面的上升，變成了地下城市，由于車輛的增多，污染了空氣，使環(huán)境變的很糟糕。

【小題1】根據(jù)while可知，這里前后是對(duì)比關(guān)系，前面提到的是好的變化，所以后面應(yīng)該是壞的變化。故第一空用bad；所以一些漂亮的動(dòng)物和植物就滅絕了，短語(yǔ)die out滅絕。故第二空用out。① bad ②died

【小題2】根據(jù)Our earth has a long history of about 4,600 million years.可知，地球上的中國(guó)有悠久的歷史。故第一空填：history。根據(jù)The competition is important to us.可知，競(jìng)爭(zhēng)很重要，所以要重視這件事。故填：serious。故答案為： (l)history(2) serious

【小題3】短語(yǔ)do something采取措施；stop sb from doing sth阻止某人做某事。故答案為：因此我們必須采取行動(dòng)阻止人們污染(我們的)地球。

【小題4】根據(jù)in the future some big cities will fall into the sea water可知，一些城市因?yàn)楹Ｆ矫娴纳仙�，所以變成了地下城市。故答案為�?/span>上升

【小題5】根據(jù)Cars and buses have polluted the air.可知，汽車和公交車污染了空氣。故答案為：Cars and buses.
