alotof和alot使用时有什么不同?

Question

a lot of和a lot使用时有什么不同?

Answer 1

a lot of 后面要“及物”,可以放在句首或句中.例如：
1) A lot of people went to the concert last night.
2) He went to the market and bought a lot of things.
a lot 是作为副词功能修饰前面的动词,因此不能放在句首用来起句.例如：
1) He thinks a lot about how he can improve his English.
2) Thanks a lot!
