题目内容
4.______ birds have come back because the environment here becomes better and better.( )| A. | Thousands of | B. | Thousand of | C. | Thousands |
分析 成千上万的鸟已经回来了,因为这里的环境越来越好.
解答 答案:A.
考查数词,表示具体数字时,thousand要用单数,后面不能接介词of.例如两千two thousand;表示概数,thousand要用复数,后接of,即thousands of,表示成千上万的,根据birds have come back because the environment here becomes better and better,这里应该表示一个概数,表示成千上万的,故选:A.
点评 考查数词的用法,理解句子的意思,注意英语中具体数字与概数的不同,利用排除法,选择正确答案.
