答案A。

   1，不明白more than all the North American Great Lakes combined是做20 percent of the world's fresh water同位语吗？

   但是more than 应该看作比较more than all the North American Great Lakes combined和20 percent of the world's fresh water作比较，如果作比较那个逗号是不是该去掉？

2， more than可以单独用吗？More than 300 rivers drain

3，more than all the North American Great Lakes combined 的是什么用法啊?是谓语还是过去分词作定语阿，如果作定语单个词应该放在被修饰词的前边阿？
