[析] 在肯定的答语中我们可以用so来代替上句所讲的事件，如：Do you think she is a good student? Yes I think so, /I hope so, /I believe so/ I'm afraid so.但在否定的答语中，英语口语的习惯用法则有所不同，如，I don't think so 而在hope, belive 与 afraid后则常用not， 如：I hope not.
[误] She didn't work enough hard, so she couldn't pass the exam.
[正] She didn't work hard enough, so she couldn't pass the exam.
[析] enough 可以作名词用，如：Enough has been said for how to learn English well. (对于如何学好英语已经讲的足够多了。) 另外它可以作为形容词，如：I have enough money (or money enough) to buy this dictionary. 注意 enough作为形容词时即可放于名词前又可放于名词后，在初中范围的考题中多用于名词之前。如果enough 作为副词用，那么它一定要放在被修饰的形容词或副词之后。
[误] You can't be very careful.
[正] You can't be too careful.
[析] 此句话的含意是你如何小心也不过分。too…to的用法是"太……以至于不能作某事"。但在实际应用时也常常将后面的to省去，如：It is too expensive for me.那对我来讲是太贵了。
[误] He is good past fifty.
[正] He is well past fifty.
[析] well 作为副词用时除用于"好"之外还有"大大地、远远地"，等意。往往有人对下面两句的对或错有争议;
He is well.
He is good.
其实这两句都是正确的表达法，只不过其含意不同。He is well是"他身体不错"，而He is good 则为"他是个好人"。
