托福语法学习：should/wouldthink＋that从句或so/not

　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。
　　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。
　　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。
