题目内容
14.Once they find people______,they decide on suitable ways to help them.( )| A. | on business | B. | in need | C. | at work |
分析 一旦他们发现人们处在危难中,他们便选定适当的办法去帮助他们.
解答 答案:B.
结合语境可以推断这句话表达的意思是"一旦他们发现人们处在危难中,他们便选定适当的办法去帮助他们.",所以设空处的介词短语表达的意思是"处在危难中",应该用in need,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.
