you'd better put your games --- and do your homework first.

You’d better put your games away/aside and do your homework first.
这是一个建议句,意思是“你最好把游戏放在一边,先做你的作业.”
1、副词 away 和 aside 都含有“保存/保留”的意思,因此 Put away / put aside 都可以表示“放在一边/收起来”.另如：
* She washed the cups and put them away/aside.她洗完杯子后便把他们收了起来.
* Put the books away/aside neatly in the bookcase.把书整齐地放到书柜里.
* The correspondence was all put away / aside in numbered files.信件都存放在编了号的卷宗内.
* I put away/aside all those useless.我把没有用的东西全部放在一旁
* She put away / aside her needlework.她放下了手中的针线活.
2、其他如 put down 和 put off 貌似可以,但是放在这里都不合适.前者表示“把…放下来使其变得不起作用”,含有“取缔、镇压、制止”的意思；后者表示“阻碍做某事”,有“拖延、丢弃、推迟,阻止,劝阻”的意思.
