初中英语情态动词题
Must I return the book today?
No,you need not.But you can return it tomorrow.
为何用can,不用must?是因为need表示必要,不是必须吗?

need 作情态动词时不用于肯定句
用must 语气强硬必须的意思前后就矛盾了
再问： need 作情态动词时不用于肯定句 @ @？
再答：一般做情态动词时用于否定句和疑问句肯定句需这样用need to do sth
再问： need的肯定否定，和它是实义动词，情态动词，是一一对应的关系吗？
再答：举例 I need to go now. 否定句 I needn't go now 或 i don't need to go now 祝你学习进步
