this为什么回答不能用youare？
this代表单数概念，this是第三人称单数主语。
主语是第三人称单数时，be动词用is
1. 如果在问句中用 this 或者 that 作主语，回答时通常用 it （而不用 this 或者 that ）作主语，即使指人也不用 he 或者 she 作主语；如果在问句中用 these 或者 those 作主语，回答时通常用 they （而不用 these 或者 those ）作主语。
例如：
(1) —Are those your sisters shoes
—No,they arent . I buy them for my mother.
(2) —The photo is very nice. Is this your mother
—Yes, it is.
(3)—Is the woman your mother
—Yes, . she is .
2.如果表语是单数名词，主语可以用this 或者that，不能用 these 或者 those；如果表语是复数名词，主语可以用 these 或者 those，不能用 this或者that。
例如：
This is my father.
That is my mother.
These are my parents.
Those are my grandparents.
These are doctors.
Those are teachers.
This is my pen.
That is your book.
These are my pens.
Those are your books.
this 和that一般用作指示代词。但this和that还可用作副词，表示程度，意思是“这么，这样地”、“那么，那样地”，一般用在非正式语体中，特别是在日常口语中。例如：
I didn＇t think we＇d get this far. 我没想到 我们会走这么远。
The table is about this high and this wide. 这张桌子大约有这么高这么宽。
I didnt realize that things had got this bad.我没有料到情况已经变得这么糟糕。
I like him but not that much. 我喜欢他，但 还不至于那么喜欢。
I would have walked out-I was that angry. 我本来是要走出去的-我是那么地生气。
Im sorry, I didnt realize the situation was that bad.对不起，我没有意识到情况是那么糟糕
