问题描述:

为什么Eating fruit and vegetables is good for your healthy里要用eating?

动词放句首要加ing变成动名词。。。这是固定用法。。。记住吧。。。

Eating fruit and vegetables这个短语才是主语。短语作主语时只能用to do或doing。再详细的一点就是动词带一个动作或带一个名词必须是to do sth或doing sth,然后再跟谓语(在这个句子里是is)。
还有,你的句子应该是Eating fruits and vegetables is good for your health。

因为动词放在开头作主语时要用ing形式.变成动名词.

【Eating】 is used as a subject.主词
eat + ing change into a noun名词
