---Must I work out the problem right now?
---Yes, you _______. It’s very serious. |
答案
| B |
解析
试题分析：A. can 能够 B. must必须 C. may 可能 D. should应该；句意：我必须现在解决这个问题吗？是的，你必须。这很危急。Must必须，对于must的问句，肯定回答用must。故选B
点评：情态动词是中考的热点，must理解为必须，由这个词所开头的问句，肯定回答用Yes,you must.否定回答用No,you needn’t或者是No,you don’t have to.注意不用mustn’t，因为mustn’t表示例行禁止的含义。情态动词在中考的考点还喜欢考can’t这个词，理解成不可能。 |
