—How many birds can you see in the trees?
—I can see        birds in them.
A.hundreds ofB.five hundredsC.hundred ofD.five hundreds of

答案
A
解析

试题分析:句意:你能在树上看见多少只鸟?我能看见数百只鸟。数词中表示不确定的数字时,数词后加s,加of, hundreds of表示数百只,故选A
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.
