1.The pen i bought yesterday_____
A.writes well B.is written well
注意write有及物和不及物兩種用法,此處是不及物.
A)（鋼筆）寫起來好用
B）被動語態(tài),也就是“鋼筆被寫”,顯然不符合邏輯,只有文字才能被寫.如果改為write with還有些道理.
2.The house the old couple live in requires_____
A.paintingB.being painted
need, want和require后面的動名詞作賓語表達被動,即“房子需要被涂油漆”其它例子如：The bike needs fixing. 想用被動表達也行,但必須把動名詞改作不定式：The house the old couple live in requires to be painted
3.If ______,water will be harmful to human life.
A.polluted （表示“總被污染”） B.being polluted（表示正被污染）
根據(jù)題意,當然應(yīng)該選 A.
