He doesn t talk____ (答案:much )但為甚麼不能用lots呢?他們的意思是什麼? 急!!!!!!?

much ia adverb;modifying comparatives ,after the verb :-
eg:-He is much better to keep quiet.
He must talk much louder.
This is much the softer.
He's not much the worse for his talk into a loud voice.
I am very much afraid that you should talk louder.

lot means a lot of ,lots and lots of,
eg:-a great amount or number of;
eg:-He doesn't talk a lot on schools.
What a lot of time he takes in talking.
He spends a lot of time on shopping.
I want lots.
I saw and heard quite a lot of him.
=I saw him often.
We don't see a lot of him nowadays because he talks too much.
He is feeling and talking a lot better today in RTHK.

He doesn't talk much.=他這個人話不多。（他是個沉默的人）
much是副詞，用來當動詞talk的「修飾語」。

lots是名詞lot的複數形，不能當副詞用，所以不符本句需要。
lots of + 名詞 ＝ a lot of +名詞
A lot of people or things, or lots of them, is a large number of them.
Lots of pubs like to deck themselves with flowers in summer.

a lot可當副詞用：If you do something a lot, you do it often or for a long time.
He talks a lot about his own children.

首先lots of一般是指可數量的東西，而且只能說"大量"而不能作反義詞"沒有"或"少"，所以這句他"doesn't"的是指"不/沒有"，動詞是指"說話"不多，所以就算用平時可以用非數量的She talk a lot來形容"她很多說話"/"她口若懸河"，也不可以在這裏寫作He doesn't talk a lotXXX。
