【解析】地球處于困境，水和空氣正在遭受污染。為了阻止污染，本文介紹了你能做的很多事情。

【1】根據(jù)前文可知：江河湖海正在被人和工廠污染。此處應(yīng)該用一般現(xiàn)在時(shí)態(tài)的被動(dòng)語(yǔ)態(tài)，主語(yǔ)是復(fù)數(shù)，故答案為are being polluted。

【2】句意：江河湖海正在被人和工廠污染。名詞用復(fù)數(shù)形式，故答案為factories。

【3】此處是動(dòng)詞不定式做目的狀語(yǔ)，故答案為to help。

【4】形容詞最高級(jí)前用定冠詞the。

【5】盡量步行、騎自行車或乘公共汽車。故答案為or。

【6】固定短語(yǔ)：turn off關(guān)掉，故答案為off。

【7】此處things做先行詞，并被不定代詞fewer修飾，所以that引導(dǎo)定語(yǔ)從句，同時(shí)在從句中做主語(yǔ)。

【8】此處是過(guò)去分詞做后置定語(yǔ)，故答案為made。

【9】句意：淋浴經(jīng)常需要大量的水。動(dòng)名詞做主語(yǔ)后面的謂語(yǔ)動(dòng)詞用單數(shù)形式，故答案為needs。

【10】根據(jù)下文的shorter，可知此處用比較級(jí)，故答案為less。
