a quantity of加可數或不可數名詞皆可

關於number和amount的區別
1、表示數量時，the number/amount of sth哪個接可數，哪個接不可數？
2、它們前面是接large/big？

an amount of +不可數名詞謂語用單數
the amount of +不可數名詞謂語用單

of.of.的用法
The protein concentrations of the supernatants of the whole cell lysate were determined using a Bio-Rad protein assay kit.這裡面有2個of，翻譯的時候，是這樣（The protein concentrations of the supernatants）of the whole cell lysate，還是The protein concentrations of（the supernatants of the whole cell lysate）這種

the nember of，a great deal，a plenty of，a lot of，四者之間的區別

yes.manyof is ok

a large number of、a lot of、plenty of、a great many有什麼區別？

記住這些在使用時就不會混淆了.例句：\x0d1、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.\x0d2、Don't hurry. We still have plenty of time.\x0dThere are plenty of such persons in our school.可數和不可數都可以.\x0d3、He got a lot of（lots of）homework（things）to do after school.可數和不可數都可以.\x0d4、They raised a great many（a good many）proposals at the meeting.只能是可數的.\x0d此外，表示大量，許多的還有a large quantity of，修飾可數和不可數名詞，如：\x0dAs 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.

a great many people
large number people
