you d better的完整形式是什么

问题描述

精选答案

you had better,you had better 后面直接加动词原形,也就是不带to的不定式,构成you had better do sth.句型。

意思是你最好做某事。这是固定搭配,适用于各种人称和时态实际上，had better do sth是固定搭配，意思是最好做某事，因为bad better是情态动词，而情态动词的后面接动词原因，所以had better的后面就接do sth一、had better 后面接不带 to 不定式，格式是：had better do sth，译为“最好做某事”，它所表达的语气很强。如果我们觉得有人不按要求或建议做会有负面结果，那么就用 had better，例如：It’s five o’clock. I’d better go now before the traffic gets too bad.现在是五点钟。我最好在交通不太拥挤之前走。You had better listen to what I'm saying before you get yourself into more trouble.你最好先听听我说的话，免得惹麻烦。

二、had best 有时可以代替 had better，用于非正式的口语中，所表达的语气没那么强或没那么直接，例如：I'd best get to bed early tonight, since I have to be at the airport at 3:30 AM.我今晚最好早点睡觉，因为我必须在凌晨3:30到机场。You had best tell her that you won't be able to come to her party.你最好告诉她你不能来参加她的聚会。

三、had better 的否定式是：had better not 或 'd better not，译为“最好不要做某事”，例如：I’d better not leave my bag there. Someone might steal it.我最好不要把包留在那里。可能有人会偷。You had better not eat so much at night.在晚上你最好不要吃得太多。
