关于 need 的考点
情态动词:need do
行为动词:need to do,need sth.
needs
needed need 为行为动词
need+n.
批注:因为 need 一词既可以当情态动词,也可以当实义动词,意思相同但形式不同,那么就很容易引起学
生的混淆,通过搭配及形式的不同可以让学生知道什么时候是情态动词什么时候是实义动词,避免错解。
典型例题

A. need to B. don't need C. needn't D. need
答案:B。本题重在考查学生对于 need 两词性的识别与辨析,横线后面的词为名词,显然这是实义动词的
need,其否定形式需要添加助动词,所以答案为 B。
