"In our city, _______ middle school students want to work as a teacher in the fut"

       "答案C

       hundred 、thousand这些量词前面有数字的下载sqlserverjdbc源码，如two thousand ，源码小说cms源码Javathousand后面绝不能加s;，下载广告赚钱app源码表示具体数字。源码引导付费软件源码如果后面加s，下载如何阅读stl源码前面则不能有数字，源码表示一个模糊地数字概念。下载

       根据题意这里中学生数量是源码概数,故选C,成千上万的."

       one是代词，本句中指代“a+city" 。此处作Shijianzhuang的同位语。

       è€Œone of后必须是复数名词，which在本句中代替的是Shijiazhuang，是单数，故不能再前面加one of。
