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

　　A Will it be expensive?

　　I should/would think so./I should think it would.I shouldnt think it would./I shouldnt/wouldnt 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：

　　Hes an astrologer， looking for work.

　　I shouldnt/wouldnt think that hed 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 shouldnt/wouldnt 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? Youd/Id 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。
