That is your crayon 肯定回答为什么主语不用that而用it？

Question

如题所述

Answer 1

That is your crayon。那是你的蜡笔。这个话题指的是蜡笔，所以回答的主语也应该是指向蜡笔，用it是也是简单习惯的用法。肯定回答：Yes, it is（my crayon）.
当然如果要回答成Yes, that is（my crayon）.也没有语法上的错误。

Answer 2

回答如下：
that是指示代词，it是人称代词。it可以指代this 或that。回答问句或用于反意疑问句时，应该把指示代词替换成人称代词。例如：
What's this / that? It is a book.
Who are these people ? They are doctors.
That is a good idea, isn't it?
Those people are on strike, aren't they?

Answer 3

一般疑问句：Is that your crayon?
肯定回答：Yes, it is.
否定回答：No,it isn't.
it是代词，避免重复，指代句里的物品。
类似的what's that？it's a pen.

Answer 4

习惯用法，that this都属于指示代词，指代物或者事情，有时也指人，回答时用it，属于语言的习惯用法，比较具体，也比较简洁。

Answer 5

it属于非人类的代词！做主语！
