题目内容
20.-Mum,____of the apples____gone bad.( )-We'd better eat up the rest as soon as possible.
| A. | one third; have | B. | one thirds; have | ||
| C. | one third; has | D. | first three; has |
分析 --妈妈,三分之一的苹果已经坏了.
--我们最好尽快吃完剩下的.
解答 答案:A.
根据语境推测句意是"--妈妈,三分之一的苹果已经坏了.--我们最好尽快吃完剩下的.",由此判断句中要使用分数三分之一,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,所以三分之一的正确表达为:one third;当分数修饰名词时,谓语动词由名词决定单复数,apples为复数,故选A
点评 做题时一定要抓住句中的关键词来确定谓语动词的使用,做到主谓一致;还要注意时态问题,必要时谓语动词要做出相应的改变.
