1._______ tigers in that forest are in danger.Now only ________ the tigers are protected.(  )
A.Hundreds; three-fourthsB.Hundreds of; three-fourths of
C.Hundreds of; three quartersD.Hundred of; three-quarters of

分析 那个森林里的数百只老虎濒临灭绝.现在只有四分之三的老虎受到了保护.

解答 答案:B.
第一个设空处根据句意"那个森林里的数百只老虎濒临灭绝."hundred 前面没有具体数词,需要与of连用,表示不具体、不准确的数目时,词尾须加-s. 第二个设空处的句意是:现在只有四分之三的老虎受到了保护.句中要使用分数四分之三,分数表达法是:分子用基数词,分母用序数词,如果分子大于1,分母要加-s,所以四分之三的正确表达为:three fourths 另外也可使用three quarters 表示四分之三.最后注意分数修饰名词时需在名词前面加of,故选B.

点评 本题考查数词的用法,在平时的学习中注意积累与运用,达到熟练掌握的目的.
