many接可数名词，例如，People cut down many trees.人们砍掉了许多树。lots of接可数名词和不可数名词均可，例如，We have lots of money!我们有很多钱！He has lots of habits.他有很多好习惯。
many和much的区别1.many和much是表示数量的不定代词，在句中既可以充当名词，也可以充当形容词，可作主语、宾语、定语、表语等，意思为“许多”、“大量”。many修饰或代替可数名词，much修饰或代替不可数名词。
2.many作主语时谓语动词用复数，much作主语时谓语动词用单数。名词前若有the/my/your/our/their/this/that/it/these/those等，此时不能直接用many/much，需用many of/much of。
3.many，much前可有as、so、too、how等进行修饰;the，these，those可以修饰many;the，this，that可修饰much。
a lot of 和 lots of的区别这两个词组可以当作定语，即当作many或much那样来使用；因此，谓语动词的数不是依据lot和lots来决定，而是依据of所引导的名词的数来决定。例如：
A lot of time has been wasted.有许多时间给浪费掉了。(a lot of =much)
A lot of people have been present.已有许多人到了。(a lot of=many)
There is lots of time to spare.时间绰绰有余。(不说 There are…)
Open meetings often reveal lots of closed winds.公开讨论往往得以开诚布公。(of引导的是复数名词)
