问题描述：
Japanese students work very hard but many are unhappy 里面的many可以说是省略了many后面student吧?
答
many代表了students的一部分
many=many of Japanese students
答
many本身就有名词许多人的意思 你可以查一下字典
答
Japanese students work very hard but many are unhappy
句意：
中国学生学习很努力但是很多人都不开心.
这里的many,直接用作代词,意思是【许多人（这里指学生）】,意思就相当于【 many students】.
不过,你也可以把它看做是【 many students】后面省略了【students】,以避免重复.
祝你开心如意!
答
可以这样说，不过我建议说成many of them are unhappy 个人觉得更好些
