题目是though ——taxes to pay for reconstruction,they could not think up a bettthough ——taxes to pay for reconstruction,they could not think up a better way.A:opposed to raise B：opposed raising C：opposed t
网友回答
答案选c.涉及到的短语：be opposed to doing sth（反对做某事）
涉及到的语法现象：如果状语从句的主语与主句的主语一致,并且谓语动词是be动词,则可将主语及谓语动词（be）省略.如
They sang their songs while (they were) playing the guitar.
He fell down off the horse when (he was) riding.
The puter broke down while being used.
另外一种类似的省略现象是：从句的主语是it,谓语动词是be动词.如
Remove the old one when (it is) necessary.
句式分析：though引导一个让步状语从句,从句的主语是they,谓语动词是were.
======以下答案可供参考======
供参考答案1:
be opposed to固定搭配，反对。这里很明显是they are opposed to,前后主语一致，分词作状语，就可以省略为though opposed to pay for reconstruction，they could not think up a better way。
供参考答案2:
opposed to
opposed是形容词
to 介词,后面跟名词或动名词
这里就是形容词作状语
oppose是个动词，oppose sth
直接跟名词的，所以如果opposing raising就对了
