题目内容

12．Grace often gets nervous before she gives a speech ．（　　）

A．

in pubic

B．

in total

C．

in common

分析 Grace在公众场合演讲前经常紧张．

解答答案：A．
结合语境Grace often gets nervous 可以推断这句话表达的意思是"Grace在公众场合演讲前经常紧张．"，所以设空处的介词短语表达的意思是"在公众场合"，应该用 in public，in total"总共"，in common"共有"都不符合句意，故选A

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．
