上句中,need to是不定式做谓语吗?是否能去掉to,need spend做谓语?谢谢!
答
能去掉to，但need to不是不定式做谓语
答
不能 ，这个是省略句，还原应该为 let you know what you need （to do is） to spend more time studing
P.S.need的用法 做情态动词时，need do
实义，need to do
表被动时 need doing
在这里need做实义动词所以不能省略to 望采纳。
答
在这里,need 和to 是分开的噢.是要把what you need 看做一个整体to 加后面的短语是做目的状语的噢!不能省to !
