常見錯誤
What are common mistakes with "Shouldn't"?Which "Shouldn't" sentences look correct but are wrong?
×You shouldn't to go to the party if you don't want.
✓You don't have to go to the party if you don't want.
混淆了「shouldn't」（不應該）和「don't have to」（不必）的用法。「shouldn't」表示建議或認為某事不是好主意；「don't have to」表示沒有義務或必要。
×He shouldn't to drive after drinking.
✓He shouldn't drive after drinking.
「shouldn't」是情態動詞，後面直接接動詞原形，不加「to」。這是常見的動詞形式錯誤。
×I shouldn't eat so much yesterday.
✓I shouldn't have eaten so much yesterday.
表達對過去行為的後悔或批評時，應使用「shouldn't have + 過去分詞」的結構，而不是簡單現在式。
×You shouldn't smoke here. It's against the law.
✓You mustn't smoke here. It's against the law.
混淆了「shouldn't」（勸告、建議不要做）和「mustn't」（禁止、絕對不可以）的語氣強度。對於法律規定或嚴格禁令，應使用「mustn't」。
×You shouldn't never give up.
✓You should never give up. / You shouldn't ever give up.
「shouldn't」本身已含有否定意義，後面不應再使用「never」等否定詞，否則會造成雙重否定，改變句意。應改用「ever」或直接使用肯定形式的「should + never」。
×If you shouldn't feel well, tell me.
✓If you don't feel well, tell me.
在條件句（if 子句）中，通常不使用「shouldn't」來表達「如果不...」。應使用一般動詞的否定式（如 don't, aren't）來陳述條件。
