Question

【题目】Every year, _________books are given away to the poor children in the countryside.

A. thousandB. thousands ofC. thousand of

Answer 1

【答案】B

【解析】

句意：每年，成千上万本书被捐到乡下的贫苦孩子。A. thousand 千，前面有具体数字时用不能变复数；B. thousands of成千上万的；C. thousand of语法错误。根据题意，这里表示约数用thousands of，thousands of books表示成千上万的书。故选B。
