A great many 後直接接複數名詞,動詞用複數.用於肯定句中,相當於many,a large number of.

例如:A great many of them have seen the film.他們中的很多人已經看過這個電影。

a great many of後主要接：

1.代詞：a great many of them

2.受冠詞脩飾的名詞：a great many of the students

3.受these,those脩飾的名詞：a great many of these students

4.受物主代詞脩飾的名詞：a great many of my students

5.受所有格脩飾的名詞：a great many of Tom's students

a large number of 表示許多的,只能脩飾可數名詞；a lot of等於lots of,即可脩飾可數的,又可脩飾不可數名詞；plenty of也是脩飾可數或不可數名詞,與a lot of同義但不如其常用；a great many只能脩飾可數名詞,等於a good many.記住這些在使用時就不會混淆了.

例句：

1、A large number of high-tec products have(has) been made in that factory(那個工廠生產了許多高科技產品）a number of做主語時,動詞可用單數,也可用複數.

2、Don't hurry.We still have plenty of time.

There are plenty of such persons in our school.可數和不可數都可以.

3、He got a lot of(lots of)homework(things)to do after school.可數和不可數都可以.

4、They raised a great many(a good many)proposals at the meeting.只能是可數的.

此外,表示大量,許多的還有a large quantity of,脩飾可數和不可數名詞,如：

As a result of destroying the forests,a large quantity of desert has coverd the land(毀林導致了大量土地的荒漠化）.On that day she received a large quantity of flowers.
