1 宾语从句的 that 不能省略。而且此处要和后面的 that 平行。

2  Run-On 结构：一个句子里不能同时出项两个主句。

3  情态动词不能随便省略 =è may 不能省。

4  词法：  the agreement … to the fact there is  不对, the fact 没有办法 agreement.

5  保持原句意思：用 there be 结构或者改变动词 agree 到 agreement 不好

6 However much的用法
在英语中在很多情况下however much= very much 是修饰动词的，由于very much 只能放在句尾而不能放在句首为加强语气，所以把however much放在句首。 
No matter how united states voters may agree MUCH that there...
表示：美国选民多么地同意.... 而不是说：“无论多少个选民同意”。看下面这个例子：
However much Mr. Robin may agree that there is waste in government and that the government as a whole spends beyond its means, it is difficult to find broad support for a movement toward a minimal state.
