题目内容
20.Tom said that he could eat ten hamburgers ______.( )| A. | in time | B. | at a time | C. | some time | D. | some times |
分析 汤姆说他能够一次吃10个汉堡.
解答 答案:B.
结合语境he could eat ten hamburgers 可以推断这句话表达的意思是"汤姆说他能够一次吃10个汉堡.",所以设空处的介词短语表达的意思是"一次",应该用at a time,其他三个选项中的短语,in time及时;some time一段时间;some times 很多次,均不符合语境,故选B
点评 英语介词的一个特点是一词多义,并且介词间语义交叉现象很多,习惯用法也很多,有时很难从词义上区分开来.故学习中要注意不断总结,熟记一些介词和动词的固定搭配用法及习惯用法,是完成此类问题的捷径.
