1.-Do you think it’s going to rain over the weekend?

　　 -________.

　　 A.I don’t believe B.I don’t believe it

　　 C.I believe not so D.I believe not

　　 命题意图：此题考查not在宾语从句中的“替代性”省略。此题属四星级题。

　　 知识依托：“so”可代替某些动词后的宾语从句，但绝不能用it或that。这些常用的动词有：believe,be afraid,expect,hope,imagine,suppose等。例：

　　 -Is she going to the party tonight?

　　 -I think so./I hope so.

　　 其否定有两种：①动词用否定结构。

　　 ②用not代替so。

　　 又如：-Do you think he will pass the exam?

　　 -I don’t think so./I think not.前者更常用。

　　 错解分析：A项应为I don’t believe so。

　　 C项否定也应否定谓语。

　　 解题方法与技巧：根据具体语言环境，正确运用表达观点的方法。

　　 答案：D
