A;several hundreds of,two hundreds of
B;many hundreds of,two hundred of
C;several hundred,two hundreds of
D;hundreds of,two hundred
必须有理由

D

two hundred of 有具体数字用单数

无具体数字用复数hundreds of

A

D!

C
several不可数所以他后面的hundred用单数不需要加s,several hundred与desks之间不用of,
two是具体数字且大于1所以他后面的hundred加S,two hundreds 与these children 之间要用of ,因为these是代词
