[誤] - Could you pass the exam this time??
- No, I am not afraid so.
[正] - Could you pass the exam this time??
- No, I'm afraid not.
[析] 在肯定的答語中我們可以用so來代替上句所講的事件，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'答語中，英語口語的習慣用法則有所不同，如，I don't think so 而在hope, belive 與 afraid後則常用not， 如：I hope not.
[誤] 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 可以作名詞用，如：Enough has been said for how to learn English well. (對於如何學好英語已經講的足夠多了。) 另外它可以作為形容詞，如：I have enough money (or money enough) to buy this dictionary. 注意 enough作為形容詞時即可放於名詞前又可放於名詞後，在國中範圍的考題中多用於名詞之前。如果enough 作為副詞用，那麼它一定要放在被修飾的形容詞或副詞之後。
[誤] You can't be very careful.
[正] You can't be too careful.
[析] 此句話的含意是你如何小心也不過分。too…to的用法是"太……以至於不能作某事"。但在實際應用時也常常將後面的to省去，如：It is too expensive for me.那對我來講是太貴了。
[誤] He is good past fifty.
[正] He is well past fifty.
[析] well 作為副詞用時除用於"好"之外還有"大大地、遠遠地"，等意。往往有人對下面兩句的對或錯有爭議;
He is well.
He is good.
其實這兩句都是正確的表達法，只不過其含意不同。He is well是"他身體不錯"，而He is good 則為"他是個好人"。
[誤] She is not as half clever as her brother.
[正] She is not half as clever as her brother.
[析] 在as…as結構中要將修飾形容詞的數量詞倍數及nearly, almost, exactly… 等置?於第一?個as之前。
[誤] He is same age as Tom.
[正] He is the same age as Tom.
[析] the same…as是固定的用法，其中定冠詞the是不可省也不能換成別的詞的。
[誤] Mother and her daughter are exactly like.
[正] Mother and her daughter are exactly alike.
* like 作為介詞，其意為"像"，應用於 look like, be like, sound like, 其後要加賓語。而 ?alike? 是形容詞，或副詞，如: You and I think alike. The twins are dressed alike。 但 alike 僅作表語而不能用於名詞前作定語。
