英语就是这样(10)...You had better go

一般上，英语中的过去完成式(Past perfect tense)的文法是用 had 然后接着是过去分词(past participle)

如 had gone, had written, had seen, had taught.

I had gone to see him. 我已去看了他。

I had taught him. 我已教导了他。

但在英语的不规则的法则 (Irregular Rule)中，HAD 接着的动词 （verb）可用动词不定式（Infinitive）来表达 如果当事人的用意是向人提出忠告或劝说等。必须注意的是接着HAD 的后面是英语的 better 然后是动词不定式（Infinitive）。

例子一： You had better go now. 您最好现在离开！(不是 You had better gone now.)

例子二： He had better take a rest. 他最好休息！(不是 He had better taken a rest.)

例子三： I had better prepare now.我最好现在准备！（不是 I had better prepared now）

所以，假如你要向你的朋友提出建议要他早点到来。 你就跟他讲：You had better come early.

有时，我们会听到：You better go now. You better take a rest 或 you better come early. 那是因为在个沟通时，我们把 had 字略省了。
