對第三題做點補充，像這種類型的句子，如果選A或D，那么它就變成兩個句子了，所以應使它從句化。具體情況因時而異，比較常用的方法是用動詞的-ing形式或過去式來表示.

1。More than half the teens surveyed,54 percent,____nothing of downloading music from the Internet。A thinks B think C show D shows答案是Ｂ　　超過一半的（54％）十多歲的孩子接受調查，表明他們對從網絡上下載音樂沒有什么異議。2。The longer you leave the problem, the worse___will become for you。A this B that C it D one答案是Ｃ　　　Ｂ為什么不行 it代表problem，一般說來it和that同時出現在選項里，要選it，it的用的比that要廣泛，而且強調性強些。3。___such a cold day, we'd better put the picnic off and stay at school。A It was B It is C It being D It has been答案是Ｃ　　　Ｂ為什么不行 如果用B，整個句子就缺少連詞了。A,D同樣是這種情況，所以即使你不知道為什么選C，也要選它。這是個因果從句，因為天氣冷，所以最好留下來。現在時表示原因。4。_____ in the United States,Detroit has now become the 10th largest city。A The fourth biggest city it wasB Once the fourth biggest cityC Being the fourth biggest cityD It was the fourth biggest city答案是Ｂ　　Ｃ為什么不行 曾經應該用過去時，being表示現在的情況，而題目里的不是。謝謝～詳解！ 。
