答案详解

1.[D]【解析】介词搭配。turn one's back against sb. 意为“与某人反目或为敌”；be kind to sb. 意为“对某人很好”。根据题意，选择D项。句意：我不应该在他贫病交加的时候与他反目，因为他一直对我很好。

2.[D]【解析】情态动词后的完成形式。must have done 表示对过去事情的猜测。句意：房间里熄灯了，特纳一家可能已经睡了。

3.[B]【解析】时态。根据题意，应该用将来完成时，因为句中有back一词，所以表示过去的“will have been to”而非“will have gone to”。句意：他明天去巴黎，他告诉我加上这次，他就去了20次了。

4.[D]【解析】比较级。no more than 意为“不比……更……”。根据题意只有D项正确。句意：研究表明：喝了酒但不过量的司机可能出车祸，不喝酒的司机也可能同样出车祸。

5.[C]【解析】虚拟语气。suggestion/order/proposal/idea 等名词引导的同位语从句用虚拟语气（should）do。所以选项C正确。句意：建议每个人都资助一位被收养的小学生。
