强调句语法？

Question

it is at least three causes that there stand for the phenomenon语法对吗

Answer 1

Answer 2

强调句的结构：It is/was+被强调部分+that +句子剩余部分。

判断这句话是否是强调句，先还原：

It is at least three causes that there stand for the phenomenon.

There stand at least three causes for the phenomenon.造成这种现象的原因至少有三个。

句子语法没错，所以，这是强调句。

there stand +名词相当于there be 结构。
