Question

自己写了一个英语句子，请高手帮忙看有什么语法错误没

Yesterday My aunt took two children coming my home, they were poor in mathematics, so I taught them to do a sum they can’t understand it.

Answer 1

应该说有错：

1. 人 be poor at

2. a sum后接定语从句they can't understand ,定语从句前省略了关系代词 that，所以，it是多余的。

3. take sb coming my home结构不符合习惯

   Yesterday My aunt took two children to my home, they were poor at mathematics, so I taught them to do sums （that） they can’t understand.

Answer 2

Yesterday My aunt took two children coming my home, they were poor in mathematics, so I taught them to do a sum they can’t understand it.

错误1.MY换成my，
错误2.coming my home，换成 to my house，coming做伴随语不顺
错误3.a sum they can’t understand it.语意不通，在sum 和 they 之间加上 but

Answer 3

coming改作to come，sum 后面再接一个what，最后一个it不要

Answer 4

Yesterday my aunt come to my home with two of her kids, who were poor in maths and need my help. Therefore, I spent a long time to help them to understand where they had been confused.

Answer 5
