高一英语单选一道~
_____ that he might be hit by other cars,Peter put a card on the back of his car reading"Caution-Newly Licensed".
[ ]
A.Concerned B.Concerning C.Having concernedD.Being concerned
请问一下为什么要选A?
答
这是常见的一种省略形式,当前后句的主语一致时,前一句可以省略掉主语和be动词,常用 做原因状语.
楼主的句子中逗号前后的主语都是peter,即
Peter was that he might be hit by other cars,(so) Peter put a card on the back of his car reading"Caution-Newly Licensed".
再举个例子
Shocked by this news,he just can't say a word.他太惊讶于这个消息了以至于说不出话来.
原句还原即是:
He is shocked by this news,he just can't say a word.
