高中情态动词题1,your sister must be at home,_______she?A,isn't Bdoesn't Cmustn't can't2,they had to catch the early bus,________they?Ahadn't Bdidn't Cmustn't Dcan't3,He must have been abroad,_______he?Ahaven't Bhasn't Cisn't Ddidn't请问关
1. A your sister must be at home. 这里MUST表推测,相当于your sister is at home. 反义疑问句,前肯后否,所以用isn't
2. B. they had to catch the early bus 这里had to 是必须的意思,过去时态,用do的过去时态,前肯后否,所以用didn't
3. B He must have been abroad,这里MUST表推测,相当于He has been abroad.反义疑问句,前肯后否,所以用hasn't
