牛津实用英语语法 231 should／would think＋that从句或so／not

（关于so／not用于代替从句参见第347节。）

A —Will it be expensive？

—I should／would think so．／I should think it would．I shouldn’t think it would．／I shouldn’t／wouldn’t think so．／I should／would think not．

—这个会很贵吗？

—我想是的。／我想不。

回答这一类问题时，回答人暗示他并不确实知道，只是凭印象而言。 I should／would think 表示的语气没有I think那么肯定。

should／would think引导一个附加评论时，一般不能用so／ not。这时必须使用that从句：

—He’s an astrologer， looking for work．

—I shouldn’t／wouldn’t think that he’d find it easy to get work．

—他是一个星相家，正在找工作。

—我想他大概不会感到找到一份工作是容易的。

B 如果评论发生在过去的动作，可以用should／would have thought：

—He actually got a job as an astrologer．

—I shouldn’t／wouldn’t have thought that it was possibe to do that．

—他真的以星相家的身份找了一份工作。

—我本来认为那是不可能的。

C should／would have expected＋不定式结构／that从句也是可行的。有时非人称代词you可代替I：

—She has emigrated．

—Has she？ You’d／I’d have expected her to stay in this country．

—她移居国外了。

—是吗？人们／我还以为她会留在国内的。
