问题解答:

我来补答
第二句对:
Which of the following would be most useful to know
第一句是病句.
句子相等于
Of the following (things),would one be most useful to know
我是加拿大人,前英语老师,英语是我第一语言.
再问: 原句是这样的:which of the following would it be most useful to know in order to evaluate the argument?你是说it不需要吗?
再答: 就你的补充, Which of the following would it be most useful to know in order to evaluate the argument? 这句子没错,这里 it 是需要的, 但这句话和上面的意思不同。 于此可见判断句意和语法上下文是重要的。
再问: 什么时候需要用it什么时候不需要呢?请问如何判断?
再答: 谢谢你的追问。 再三考虑后,我认为和第一句一样,第3 句也应该没有 it ,即 Which of the following would be most useful to know in order to evaluate the argument? 句子是否含有短语 in order to evaluate … 不是关键。 如果我们把句子简单化,把时态改为 is : Which of the following is useful to know … 句子是 which one of the following things is useful to know … 的省略句。 要是加 it 句子就变成病句了。 这不只是语法的问题,也是语感的问题。
