Phil has already finished his report,so he_work on it on it any more.
A.needn't B.doesn't need C.needn't to D.not need to
我对needn't not need to啊什么的搞不清,马上就要考试了
Phil has already finished his report,so he_work on it on it
选A
need do: 情态动词 ---换成can来判断
need to do & need sth. 行为动词 ---- 换成like来判断
再问: 能不能解释得清楚点啊,有点晕
再答: 一个题目拿来。你先把need换成can看有没有语法错误。He can speak English 不行在换成like He likes English. He likes to learn English. 这三个句子换否定句会简单些吧! need 的用法也这样。
再问: 情态、实义有什么区别啊
再答: 情态动词常见的就几个:can, must, need , may, could, might should be able to have to ought to, had better, would rather 行为动词就是我们经常说的动词。watch, see, like, call等
