Answer 1

分析 You'd better not．

解答 答案：You'd better not．结合句意表达最好不要做某事用had better not do sth，主语you，与had缩写成you'd，故答案是You'd better not．

点评 had better基本特点是编辑1、其后接不带to的不定式，表示现在或将来的概念，如：You had better sit here and have a rest．你最好在此坐坐休息一会儿．（现在）He had better stay in bed tomorrow．他最好明天卧床休息．（将来）．2、当其后接 have 加过去分词时，表示过去概念，如：He had better have stayed in bed as I suggested．他最好接纳我的意见卧床休息．（但他没卧床休息）You had better have had tea，but you asked for coffee．你最好喝茶，但却你要了咖啡．3、had better 的否定式是在其后加not，如：You had better not say it again．你最好不要再提那件事了．
