Need to help.than后面跟主格还是宾格?我看见书上为什么两种都有? 关于need 的用法的一句话He needs study harder than before.这里need后面直接跟study原型对吗?还是 need to studyneed 表示情态动词? need 后面跟什么 need后面跟什么 want to do sth ,seem to do sth ,help to do sth,need to do sth.等,这些动词后面都有to do,什么情况下动词后面要跟to do help后面跟动词,要加to吗?help do ,还是help to do? I need to help! He needs someone to help him.这个句子对不对,need后面能不能接复合宾语? 为什么是need help而不是need to help need help to do 还是 need help doing need help to do 还是 need help doing better to do rather than后面跟do 还是to do? there is no need 后面是跟doing还是to do don't need 后面跟doing还是to do还是do need sth后面跟什么介词 I want him to help you.请问want后面跟宾格吗 help oneself 后面可以跟doing吗? help后面跟主格还是宾格?
