Question

a lot of和a lot使用时有什么不同？

Answer 1

a lot of与a lot ，一个of之差，用法大不一样。

Answer 2

a lot of 和lots of意思基本上是一样的，就是many，mucha lot是一个很灵活的副词性短语比如你自己说的My pig eats a lota lot 做副词，是eats这个动作的补语再比如My dog eats a lot more，我家狗狗吃得更多这里的a lot 做副词修饰more，三个词连在一起修饰eats。这么说你明白了么？a lot其实本身是多的意思，后来引申为十分，非常，比如Thanks a lot 十分感谢，太谢谢了这个总不能是很多感谢吧=。=首先要说的，是英文没有lot of,a lots of,a lots这说法。A lot of和lots of都是“很多”的意思，用法有两点值得注意。第一，a lot of和lots of都可用来说可数（countable）或不可数（uncountable）名词，而动词应用单数或复数形式，则看那名词而定，和a lot或lots无关。例如“A lot of/Lots of money was lost.（损失了很多钱。）”一语，lots之后不用were；“A lot of/Lots of people were wounded.（很多人受了伤。）”一语，a lot of之后也不用was。第二，many/much和a lot of/lots of意思相同，但语气上，many和much没有a lot of那么随便，a lot of又没有lots of那么随便。所以，a lot of / lots of不宜用于谨严的写作，多见于口语；但问句、否定句口头上也多用many和much。例如甲问：“How much time have we?（我们有多少时间？）”乙可以说：“We haven't much time.（我们没有很多时间。）”或“We have a lot of/lots of time.（我们有很多时间。）”向人道谢，说“Thanks a lot!”也比“Thanks very much!”随便。此外，年、月、日、时等时间单位，不可和a lot of/lots of连用，例如“I lived in Macau for many years before coming to Hong Kong.（我在澳门住了多年才来香港。）”一语，many不可改为a lot ofbaraclue

Answer 3

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!
