英语改错问题。

Question

She spent a lot of spare time help us with our english,这句话哪里错，为啥错？

Answer 1

去问问你的英文老师吧、这个我其实不懂

Answer 2

去掉have
比改成It
has
been
的意思跟原句的意思更接近

Answer 3

主句用这两种都可以
但It's更常用
而since从句应用一般过去式

Answer 4

spend sb/sth (in) doing sth ,help -helping ,括号里的in可省略 ！

Answer 5

应该是：
She spent a lot of spare time helping us with our English.

spend...(in)doing，是固定用法
