英语语法,请教一下解析的过程 ( ) to find words to express their gratitude,they silently grasped their hands.
选项:
a、they are unable
b、been unable
c、unable
d、as unable
答：C
译：不知道如何表达他们的感激之情,他们静静地紧握双手(抱拳表示感谢,一定是中国人.）
析：形容词短语作状语,表示原因=As they were unable to .
评：D项也是可以的.
我们知道,分词短语（包括形容词短语）可以作状语,实质是省略了连词+主+be动词.有时候为了明确是什么状语,前面保留连词如：When heated,water will become vapour.= When it is heated,...
If it is necessary,I will help you.==》I will help you if necessary.
As unable to ...=As they were unable to ...,
本题设计有误.
C
d
答案是C。
A不能选，因为选A的话，句子前面一半就是They are unable to find ...，是一个完整的句子；而后半句也是一个完整的句子。两个完整的句子之间不能用逗号来连接，所以错了。
B显然是错的，如果是Being unable 是可以的。
D也不能选，As放在句首可以作连词表示原因，应说完整As they were unable 才对。
选C正确...

答案是C。
A不能选，因为选A的话，句子前面一半就是They are unable to find ...，是一个完整的句子；而后半句也是一个完整的句子。两个完整的句子之间不能用逗号来连接，所以错了。
B显然是错的，如果是Being unable 是可以的。
D也不能选，As放在句首可以作连词表示原因，应说完整As they were unable 才对。
选C正确，这儿是用形容词作状语，说明主语they的情况，表示原因。
再如：Curious about everything, the baby looked around.
收起
C
当主从句的主语一致，并且从句的谓语动词含有be动词时，从句的主语和这个be动词可以直接省略，所以选C，补充完整的话就应该是“（they were）unable to find words to express their.......”
