There are about _________ teachers and students in their school. A．three thousands B．three thousand C．thousand of D．three thousand of

Answer 1

B
试题分析：英语中数词表示概数时，后面加s，和介词of搭配使用。用原形时表示具体数字和数词搭配使用。句意：在他们学校大约有三百老师。结合语境可知本句表示具体数字，故选B。
点评：英语中关于hundred、thousand和million三个数词的用法只需要记住一个原则就行。即；前有数词则不加s，加s必加of。
