英语语法纠错

Question

need sb do sth
donot need sb to do sth
need sth to do

Answer 1

need是情态助动词，也可以做普通及物动词
上面三句话是把need作为情态动词的用法和作为及物动词的用法混用，don't need是及物动词用法，need to为情态动词用法
想表示否定的意思，可用need not do sth表达

Answer 2

need sb to do sth
donot need sb to do sth
need sth to be done

Answer 3

第三个 应该是 sth need doing 吧，是主动语态表示被动意思 e.g the classroom needs cleaning.

Answer 4

need sb to do sth
don't need sb to do sth
need sth to be done
