a number of 与a lot of的区别

都是表示很多的意思,似乎没什么比较大的区别。
a number of 加可数名词的复数
a lot of 即可加可数名词的复数也可加不可数名词
a large number of 表示许多的,只能修饰可数名词;a lot of等于lots of,即可修饰可数的,又可修饰不可数名词;plenty of也是修饰可数或不可数名词,与a lot of同义但不如其常用;a great many只能修饰可数名词,等于a good many。记住这些在使用时就不会混淆了。例句:
1、A large number of high-tec products have(has) been made in that factory(那个工厂生产了许多高科技产品)a number of做主语时,动词可用单数,也可用复数。
2、Don't hurry. We still have plenty of time.
There are plenty of such persons in our school.可数和不可数都可以。
3、He got a lot of(lots of)homework(things)to do after school.可数和不可数都可以。
4、They raised a great many(a good many)proposals at the meeting.只能是可数的。
此外,表示大量,许多的还有a large quantity of,修饰可数和不可数名词,如:
As a result of destroying the forests, a large quantity of desert has coverd the land(毁林导致了大量土地的荒漠化). On that day she received a large quantity of flowers.
a number of : 接可数名词
a lot of:可数,不可数都行。
a number of + 可数名词复数
a lot of + 可数/不可数名词复数
他们的意思都相同
