这个句子为什么要放个of?Which of the following is ture?

问题描述:

这个句子为什么要放个of?
Which of the following is ture?

对头
which of these is ture?

of 是介词,表示在...范围之类

Sth of the following is ture.
如果没有of
sth the following is ture.你觉得对么?
sth 是名词 the following 也是名词。

因为是在following中择其一

of the following
你可以把这一句去掉 即:which is true .
这样好明白么?

which is ture of (the following )/(these)?就是其中之一的意思, 变成these看看是不是不能不加of 阿
