在做适当形式填空时,怎么知道是填need to do,还是need do?

need的否定形式可以是need need to do sth为啥在否定形式时不可以呢?need doing sth在否 how much____（rice）do you need?适当形式填空 need必须是to do形式吗? need的用法?need to do还是need do? need to do 还是need doing ... do you need to do… 和need you do…?怎么区分?如何判断疑问词用do还是need? 是you need do what you should do 还是you need to do what you sh you need more pracitce 这里的practice是动词还是名词.need to do 和 need need to do ,need doing need to do的否定形式 用所给单词的适当形式填空 what do you_____(need)? 适当形式填空 What should I( )[do] Our body ( 身体） （ ） [need]much wa
