lot, many, many a, plenty of 有什么区别？

--------------------------------------------------------------------------------------------------

    问：请问 lot, many, many a, plenty of 有什么区别？谢谢。

    答：lot 在口语中表示“大量，许多”时，单数和复数具有同样的意思。比如：He has a lot of friends. (他有许多朋友。) / I want lots of food. (我要大量的食物。) lot和lots单独使用时都是单数。比如：There is lots to see.（有许多东西可看。）后面接介词of时，谓语动词的单复数与of后面的名词一致。比如：A lot of men have arrived.（许多人已经到了。）/ Lots of money has been saved up.（省下了许多钱）

    many和many a (an)的意思相同。但是，many a (an) 常用于书面语，并且后面接的名词要用单数形式，语气比较强。比如：I took so many photos the first day.（我第一天拍了那么的多照片。） / I have sat invisible beside you many and many a day.（我不露面地坐在你身边已经有好多好多天了。）

    plenty of可以用来修饰可数名词或不可数名词，但是当后面接名词作主语时，谓语动词的数要与of后的名词保持一致。比如：Plenty of sugar is already here. （这里已经有许多糖。）/ There are plenty of eggs in the house. （屋子里有许多鸡蛋。）
