Answer 1

分析 You'd better not．

解答 答案：You'd better not．結(jié)合句意表達(dá)最好不要做某事用had better not do sth，主語you，與had縮寫成you'd，故答案是You'd better not．

點評 had better基本特點是編輯1、其后接不帶to的不定式，表示現(xiàn)在或?qū)�來的概念，如：You had better sit here and have a rest．你最好在此坐坐休息一會兒．（現(xiàn)在）He had better stay in bed tomorrow．他最好明天臥床休息．（將來）．2、當(dāng)其后接 have 加過去分詞時，表示過去概念，如：He had better have stayed in bed as I suggested．他最好接納我的意見臥床休息．（但他沒臥床休息）You had better have had tea，but you asked for coffee．你最好喝茶，但卻你要了咖啡．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．
