A. must B. can C. may D. have to ②( )I thought I smell something burning. A. can B. could C. may D. have to 4). have to不能直接用来否定或提问,需要助动词do / did / does等帮助。 而其他的情态动词一般都可以直接进行否定和提问。例如: ①( )What she do? A. has; to B. does; has to C. does; have to D. have; to ②( )You help her with her homework. A. don’t have to B. haven’t to C. mustn’t to D. don’t to ③( ) come in? A. Do I may B. May I C. Have I to D.
