Question

let+人称宾格,后面动词要原型吗,动词后的名词呢?
还有,不是说finish doing sth 是固定搭配,可是这个句子为什么只填finish?
My sister can (finish)the work before supper.【finish】
如果是finished 后面动词用不用也是过去式的?
介词后面动词都要ing形式吗?
有没有What about to……的短语搭配的吗?
inside和in意思相同吗?
each后面名词用变复数吗?{pl}
I usually go with my parents or friend.的提问可不可以是who go to with you
一定要是who do you usually go with
how many 后面名词一定要是复数吗?
want to后面动词要原型吗?还是to 后面都要加?
can 加动词原形么?

Answer 1

let sb.do
finish Sth/ doing sth 不管finish如何变化,后面的都不用变
介词后面动词都要ing
What about doing sth.
each 后接单数名词
不可以是who go to with you 应该是Who do you usually go with?
how many 后面名词一定要是复数
want to do 应该区分to是介词还是不定式符号,如果是介词后接doing,如果是不定式符号,接do
can 加动词原形
