    答案是Ａ．我选Ｃ．

   能帮我解释一下么？　　谢谢～～～

sb recommend that...要用虚拟语气，虚拟语气的用法已经有很多说明了，简单的说一般现在时用should do，其中的should书面语中要省略，所以就成了be

谢谢楼上两位！

我还想问的是 (D)选项,除了them的错误之外，和（Ａ）相比，还有什么用的不好的地方么？

有be ground for doing 和be ground to sth

be ground to do 是不对的

再请教一下be ground for doing 和be ground to sth分别是什么意思啊?

谢谢~~

作为....的依据

哦,谢谢~~
