_a certain doubt among the students as to the necessity of the work. 为什么用there excisted 而不用it

Question

如题所述

Answer 1

你好。其实，there is / was 或there exists / existed在你的句子裏面的使用并没有什麼区别. simply a personal preference by the 出题人。 你不用纠结。追问

我的意思是为什么用 there 而不用it开头呢

追答

ok 非常简单。 there to be / to exist强调的是一种“在某个时间某个地方”存在-- - -。如果没有sb做主语，你就用there to be / exist结构。
如果用 it 开头，句子就成了： it is doubtful among the students whether the work is necessary at all.

一般来说
1 there is / are + 名词
2 it is + 形容词

Answer 2

本句型是倒装句：There + be动词或不及物动词+主语(名词)
There is a book on the desk.
There comes a man of fifty.
There followed a group of children.本回答被提问者和网友采纳
