(单选题)

—Must I finish the task today?
—______. You can hand in it by Friday.

A.Yes, you must

B.No, you mustn’t

C.Yes, you should

D.No, you needn’t

参考答案：D

参考解析：

考查情态动词表许可。句意：“我今天必须完成任务吗？”“不，你不需要，你可以在星期五前交上来。”根据后半句“You can hand in it by Friday”可知，此处表示否定回答；must的一般疑问句的否定答句应该使用“No, you needn’t”或者“No, you don’t have to”。故选D。

知识点：

—Must I finish the task today?—______. You can hand in it by Friday.

—Must I finish the task today?
