问题
选择题
Their school has more than two _____ teachers and _____ students.
A．hundreds of, thousands of
B．hundred, thousands of
C．hundred of, thousand
D．hundreds, thousands of
答案
答案：B
题目分析：句意：他们的学校有两百多名老师和数千名学生。数词表示确定所指时数量单位不加s,不加of,表示不确定所指时加s,加of,故选B
点评：单位数量词，表示确定所指时不加s,不加of；表不确定所指时加s,加of，这是相对于后面直接接名词来讲的，而本题中of存在所属关系，所以要特别注意区分，而诸如这种情况就要加，如：hundreds of people.
