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.
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.
With 20 percent of the world's fresh water, that is more than all the North American Great Lakes combined, Siberia's Lake Baikal has more than 300 rivers that drain into it.
Siberia's Lake Baikal, with more than 300 rivers draining into it, it holds more of the world's fresh water than all that of the North American Great Lakes combined, 20 percent.
While 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.
More than all the North American Great Lakes combined, Siberia's Lake Baikal, with more than 300 rivers draining into it, holds 20 percent of the world's fresh water.
题目分析：
本题难度较大，需要仔细区分成分及语意方可找到答案。
选项分析：
A选项：Correct. 本选项在语法和逻辑上均是正确的。
B选项：that is more than all the North American Great Lakes combined是定语从句，但非限定性定语从句不能用that来引导，只能用which。另外，在主句部分，我们不能说Siberia's Lake Baikal has more than 300 rivers，即，Baikal不能拥有300条河，只能是三百条河流入Baikal。
C选项：语法有误。Siberia's Lake Baikal和代词it均是holds的主语，这造成了一个句子有两个主语。另外，with more than 300 rivers draining into it是独立主格结构，其是holds句的状语。在逻辑上，三百条河流入Baikal应是在描述Siberia's Lake Baikal的性质的，而描述名词的均应该是定语，不能使用状语。
D选项：状语从句while more than 300 rivers drain into it有误。它在修饰主句hold这个动作。但在逻辑上，“300条河流入”和“湖里的水占据了多少百分比的全球淡水”之间没有时间关系。也就是说，不能说“当300条河流入的时候，湖里的水就占了20%”。这好像是给“占20%”加了一个限定的时间。
又或者，现在如果突然所有的河都不流入了，短时间内这个湖逻辑上还是会占20%的淡水的。因此，不能用“流入”这个动作来做“占据”的时间状语。
E选项：with more than 300 rivers draining into it是独立主格结构错误同选项(C)。

D选项：定语从句which is more than all the North American Great Lakes combined应就近修饰，这里只能修饰20 percent of the world's fresh water，这是不正确的。该定语从句描述的在逻辑上应是Siberia's Lake Baikal的特点。
E选项：with more than 300 rivers draining into it是独立主格结构错误同选项(C)。
B/C/D好排除
错选E，补充知识点如下：
with结构表独立主格，修主句动词，做状语，E选项想让with结构修主句主语，错误，排除！
e. "More than all the North American Great Lakes combined"修饰 baikal, 修饰对象不对， 修饰对象应该是的water
when you have an INITIAL MODIFIER THAT'S NOT A CLAUSE (i.e., it doesn't have its own subject and verb), then it must modify the immediately following noun. in choice (e), which implies that lake baikal itself is somehow "more than all the North American Great Lakes combined".
that doesn't make sense.
The entire phrase "more (water) than all the North American Great Lakes combined" is an appositive, a noun phrase used to modify another noun phrase.
A的MORE THAN 是省略形式，前面可以加上WHICH IS
A句子中的谓语动词是什么啊？
drain into

根据老师讲解， A vs E 用独立主格 with more than 300 rivers draining into it 只能做状语，不能做定语修饰Lake Baikal。而A 的定语从句，which holds 20 percent of the world's fresh water， 可以修饰Lake Baikal。
This is the right answer I think!

定语和状语
More than 300 rivers drain into Siberia's Lake Baikal, which holds 20 percent of the world's fresh water, （就近修饰 20 percent of the world's fresh water more than all the North American Great Lakes combined.）
（More than all the North American Great Lakes combined,就近修饰siber lake baikal 不对等） Siberia's Lake Baikal, with more than 300 rivers draining into it, holds 20 percent of the world's fresh water.
这里同位语从句“more than all the North American Great Lakes combined”修饰的是前面的定语从句，而不是某个名词。
RON原话：“more than all the North American Great Lakes combined” is an appositive modifier; these modifiers have considerable flexibility, and can be taken to refer either to a noun or to an entire clause.
“more than all the North American Great Lakes combined”修饰“20% of the world's fresh water".
more than all the North American Great Lakes combined 对比的是lake的含水量
独立主格和伴随 很关键，状语和定语的区分 感觉考很多次
搬自GMATCLUB: 感觉老师D的讲解有误 Lake B can not be more than all the North American Great lakes combined....It is the water in Lake B.
感觉你说的有一定道理。 我觉得D是while上加了一个逻辑关系就有问题。

A. which holds... 修饰 Baikal, more than all the... 是 which holds 20 percent... 的同位语。
B. that不能引导非限制性定语从句，应用which
C. with more than 300... 是插入语，可删除，删除后变成Siberia's Lake Baikal it holds... 双主语，应去掉it
D. which就近修饰前面的名词fresh water, 不能只说fresh water more than all the North American Great Lakes combined，语义不符
E. 变成了 siberia's lake baikal more than all the north american great lakes，比较对象不对
(D) while作为连词表示当…的时候或者表示转折,而原句并没有这种逻辑关系; which引导的非限定性定语从句就近修饰fresh water, 而从逻辑上应该修饰20 percent of the world’s fresh water
(E)将Baikal和北美5大湖直接进行比较,概念不对等,给人错觉像是比较五大湖和贝加尔湖的面积--有歧义， 应该是Baikal的水量和五大湖的水量进行比较.
限定性从句和非限定性从句: 限定性定语从句对先行词起限制、确定作用,与先行词有着不可分割的联系,它的前面通常没有逗号;非限定性定语从句与它的先行词之间只有比较松散的关系,通常用逗号将它与主句隔开
A正确, 非限定定语从句which holds…就近修饰Lake Baikal; more than all the…作为20 percent of the world’s fresh water的同位语
B that引导限定性定语从句前面不用逗号隔开, 而此处去掉that从句并不影响原句的主要意思,因此应该用which引导的非限定性定语从句表明两者之间松散的逻辑关系, 但即使改为which引导的非限定性定语从句,which也只能修饰fresh water仍然意思不对; has more than 300 rivers that drain into it表达笨拙,不如A的结构简单
错选D，定语从句which应就近修饰
按照D的解释，more than all the North American Great Lakes combined就近修饰20 percent of the world's fresh water,那么A选项也会出现了类似的问题，同样也是修饰20 percent of the world's fresh water？所以D选项是不是因为while的原因造成的啊？
