Question

We've bought ________ desks for the children, and ________ these children have been to our school.

1. A.
   several hundreds of; two hundreds of
2. B.
   many hundreds of; two hundred
3. C.
   several hundred; two hundred of
4. D.
   many hundreds; two hundred of

Answer 1

C
点拨：several和many虽然不是明确的具体数字，但也起限定作用，故hundred不加s，不带of，故排除掉A、B和D。注意，C项中的two hundred是代词而不是起形容词作用。
