manytoo后加什么？

没有many too这种用法。一般是too many，后面加可数名词复数，意为太多。

例句

Too many poor people are living in overcrowded conditions.

有太多的贫民生活在十分拥挤的条件下。

I soon learned not to ask too many questions.

我很快就意识到不能问太多的问题。

I can certainly feel the effects of too many late nights.

Too many examples can interrupt the smooth flow of the text.

例子太多会使行文不流畅。

如今有太多的人在角逐寥寥无几的工作职位。
