Had better的用法

Had better: 形式和含义

我们用had better来指代现在或将来，来谈论我们认为人们应该做的或在特定情况下可取的行为。动词形式总是had，而不是have。在非正式场合，我们通常把它缩短为' d better。它后面跟着不带to的不定式:

It’s five o’clock. I’d better go now before the traffic gets too bad.

Not:

I’d better to go now.

The democratic movement had better concentrate on the immediate issues of the economy and security. (more formal)

Had better是一个强烈的表达。如果我们认为如果某人不按照期望或建议去做，就会产生负面结果，我们就会使用这个短语:

She’d better get here soon or she’ll miss the opening ceremony.

Spoken English:

有时人们会说had best而不是had better，尤其是在非正式谈话中。这听起来没有那么强烈和直接:

You’d best leave it till Monday. There’s no one in the office today.

Had better: 否定和疑问形式

had better的否定形式是had better not(或' d better not):

I’d better not leave my bag there. Someone might steal it.

You’d better not tell Elizabeth about the broken glass – she’ll go crazy!

had better的疑问句形式由主语和had颠倒而成。这和should的意思一样，但是更正式:

Had I better speak to Joan first before I send this form off? What do you think?

Had we better leave a note for the delivery guy to take the parcel next door?

带有had better的否定疑问句比带有肯定疑问句更常见:

Hadn’t we better ring the school and tell them Liam is sick?

Hadn’t you better switch your computer off? It might overheat if you leave it on.
