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．
