当need为行为动词和情态动词时有什么差别?如何区别?
这里有道选择题:
(D )I don't think your friend(这是一条横线)worry about his health.I think he'll be all right soon.
A.needed B.needs C.need to D.needs to优质解答
行为动词:一般为need to do sth ,用法与like to do sth 相同,所以对行为动词提问的时候为“what do you need ”等,有人称变化,比如he needs to go to school
情态动词:此时need的用法与can ,should .等相同,没有人称变化形式,后跟动词原形,比如说he need go to school ,对情态动词提问直接是“need you go to school”
这道题目中,首先判断为一般现在时,所以排除A,如果选择B,表示need为情态动词,不需要第三人称单数,排除.选C,表明need为行为动词,因为是your friend ,所以为第三人称单数,要加S,所以选D
