英语选择题一题

Saving resources is a basic policy of our country.And it proves ________ to its sustainable development.
A.to be great significance B.to be of great significant
C.of great significance D.great sifnificant
“prove”后不是跟名词吗？因此我选的是D，但答案是C，为什么？

望高手赐教，谢谢！！！！！

Answer 1

of great significance 本身就是一个名词词组。 of great 作为程度词来形容significance ， of great significance =very significant

Answer 2

原句大意可能是“节约资源是我国一项基本的国策 它证明我国走可持续发展道路” prove 后可以加名词 prove+介词短语的时候 是结果证明的意思
prove+介词短语或副词

例句：Perhaps this book will prove of some use to you in your studies.也许这本书会对你的研究有用处.

The power station was completed and proved up to standard.这座发电站建成了,证明质量符合标准.
我只能这样想了(*^__^*) 嘻嘻……( ^_^ )/~~拜拜
