分析 那個森林里的數(shù)百只老虎瀕臨滅絕.現(xiàn)在只有四分之三的老虎受到了保護.

解答 答案:B.
第一個設(shè)空處根據(jù)句意"那個森林里的數(shù)百只老虎瀕臨滅絕."hundred 前面沒有具體數(shù)詞,需要與of連用,表示不具體、不準確的數(shù)目時,詞尾須加-s. 第二個設(shè)空處的句意是:現(xiàn)在只有四分之三的老虎受到了保護.句中要使用分數(shù)四分之三,分數(shù)表達法是:分子用基數(shù)詞,分母用序數(shù)詞,如果分子大于1,分母要加-s,所以四分之三的正確表達為:three fourths 另外也可使用three quarters 表示四分之三.最后注意分數(shù)修飾名詞時需在名詞前面加of,故選B.

點評 本題考查數(shù)詞的用法,在平時的學習中注意積累與運用,達到熟練掌握的目的.
