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 of
