讲解新词汇novel和短语had better(not)do sth.的用法。
You’d better go to bed earlier tonight, if you can.
had better加动词原形表示：最好做某事，用来向别人提出建议。可缩写为：’d better。如：
You’d better watch carefully before you cross the road．过马路之前你最好要看仔细。
We’d better hurry up，or we’ll be late．我们最好快一点，要不然就晚了。
如果建议别人最好不做某事，使用“had better not加动词原形”这一句型。如：
You’d better not read in bed．It’s bad for your eyes．你最好不要躺着看书，对你眼睛不好。
You’d better not play basketball after lunch．It’s bad for your health．你最好不要在午饭后就玩篮球，它对健康有害。
