More than 300 rivers drain into Siberia's Lake Baikal, which holds 20 percent of the world's fresh water, more than all the North American Great Lakes combined.
(A) {主句)More than 300 rivers drain into Siberia's Lake Baikal, {非限定定语从句}which holds 20 percent of the world's fresh water, {定语从句的比较状语}more than all the North American Great Lakes [are]combined[with rivers].
(B) With 20 percent of the world's fresh water, that{that 不引导非限定性定语从句} is more than all the North American Great Lakes combined, Siberia's Lake Baikal has more than 300 rivers that drain into it.
(C) Siberia's Lake Baikal, with more than 300 rivers draining into it, it{多主语} holds more of the world's fresh water than all that of the North American Great Lakes combined, 20 percent.
(D) While {逻辑关系不清,时间还是让步状语? }more than 300 rivers drain into it, Siberia's Lake Baikal holds 20 percent of the world's fresh water, which is more than all the North American Great Lakes combined.
(E) More than all the North American Great Lakes combined, Siberia's Lake Baikal(跟前边的主语不一致,比较的对象是水,不是湖), with more than 300 rivers draining into it, holds 20 percent of the world's fresh water.
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?
