be helpful to是什么意思

Question

如题所述

Answer 1

sth. is helpful to sb. ……对某人有助
....is helpful to sth. 对……有助

it is helpful to do sth. 做……是有好处的
It is helpful for sb. to do sth. 某人做……是对他有好处的
这两个都是it 做形式主语
helpful 是表示“有好处”，而不是“有助的”

下面这两个是“有帮助的”
it is helpful in doing sth.
sth. is helpful to sth./ doing sth. 前面的sth.一般是具体的某个事物，如the book is helpful to our improvement 当刚好变成it is helpful to sth.时，那个it是因为前面已经说了是什么东西，这里是代词it来指代同一个东西，其实归根到底还是sth. 后面那个doing sth.就是动名词来充当名词成分

希望帮到你 望采纳 谢谢 加油
