剑桥MSE基础语法丨Had better的形式和意思

比如：

非正式: It's five o'clock. I'd better go now before the traffic gets too bad.

正式:The government had better take the will of it's citizens into consideration.

Had better是一个较为强烈的表达。当我们认为如果某人不按照要求或建议去做，就会产生负面的结果时，我们就会用这个短语，比如:

She'd better get here soon or she'll miss the opening ceremony. (负面结果)
她最好快点来，否则她会错过开幕式。

在口语表达中，特别是在非正式的交谈中，有时候也可以使用had best，比起had better， had best更加温和委婉。例如：

You'd best leave it till Monday. There's no one in the office today.
你最好把它留到星期一。今天办公室里没有人。
