题目内容
14． of his time been spent on studies every day．（ ）| A． | Three fourths；has | B． | Three fourths；have | ||
| C． | Third fours；has | D． | Thirds four；have |
分析 翻译：他每天花四分之三的时间学习．
解答 答案：A．在英语中的分数，先说分子数后说分母数，分子用基数词，分母用序数词，当分子大于一时，分母要用复数形式；因此四分之三表达成three fourths；现在完成时的被动语态的肯定式构为：主语+have/has+been+动词的过去分词；时间是被花费，time是谓语动词spend的动作承受者，因此该用被动语态；time作为"时间"是不可数名词，故用has；故选A．
点评 本题主要考查的是分数的表达，先说分子数后说分某数，分子用基数词，分母用序数词，分子数超过"1"时，分母用复数
