英语语法疑惑

我终于找到答案了。
1. expect so / not 的用法
在动词think，expect，believe，suppose，fancy，fear，hear，hope，imagine 等词后面可以用 so 代替上文所提及的名词、形容词或从句，如：I think / believe/ suppose / imagine / expect / hope / am afraid so。否定句里也可用not。如：I don't t hink / believe / suppose
/ expect so 或 I think / believe / suppose / expect / hope/ am afraid not，
但不说 I don't hope / guess / fear so.

【单项选择】

( ) 1. -- Do you think it's going to rain over the

weekend? -- ____.

A. I don't believe B. I don't bdieve it

C. I believe not so D. I believe not

( ) 2.-- The boys are not doing a good job at all, are they?

-- ____. (2003 北京春招)

A. I guess not so B. I don't guess

C. I don' t guess so D. I guess not

【参考答案及简析】

1. 选D believe可以说I believe so，I don't believeso，I beIieve not．

2. 选D guess可以说I guess so，I guess not，但不说I don't guess so.

得说i don't think so。没见过 I don't guess so think一般不用I think not

guess不同于think，think存在否定转移，guess不能这样，回答完毕
