In our city, ___ middle school students want to work as a teacher in the future. [重庆]
A. thousand B. thousand of C. thousands of D. two thousand of
答案为C。thousands of表约数概念，此时，不能和具体数字连用。
The road is over _____ metres long．[济南]
A．six hundred and fifty-two B six hundreds and fifty-two
C．six hundred，fifty-two D．six hundred，fifty and two
[答案]A。[解析]本题考查数词的书写形式。在英语中，百位与十位之间通常用and连接，由此可知，答案在A与B之中，在表示确切的数字时，hundred不能用复数形式。
