问题描述:

1.he usually does his housework at night.改为否定句

he never does his housework at night.

He never does his housework at night.
改变频率副词使句子变否定。

He usually doesn't do his housework at night。
do one‘s housework 是做某人的家庭作业
do是实义动词,(题目中因为主语是he所以用第三人称单数dose),变成否定句时,要借助助动词do,再根据主语是第三人称单数改成dose,再加上not 就可以了

He usually doesn't his housework at night.

否定句:He usually doesn't do his housework at night.
方法:因为主语是第三人称单数he,于是借助助动词does,且改为否定,也就是doesn't ,再放在实义动词do的前面.就可以了:)
