你的题目应该是同义句转换吧，你没有说清楚，如果是的话应该填入：
1.my mother told me to finish my homework.不定式符号to后接动词原形。
=she told me that i shold finish my homework first.
2.mum found a mouse eating the chicken on the table.因为妈妈发现的时候，老鼠正在吃鸡肉，所以用现在分词形式。

finish， eating

tell sb to do sth 告诉某人做什么
find sb doing sth 发现某人/某物正在做什么
整句翻译 我妈妈告诉我先完成作业。
妈妈发现有只老鼠正在桌子上吃鸡肉。

My mother told me to （finish）my homework first. She told me that( I must finish my homework first .)
5.Mum found a mouse (eating )the chicken on the table.

finish
tell sb to do sth 吩咐某人做什么
eating
find sb doing sth 发现某人在做什么
