33. (26233-!-item-!-188;#058&002541)

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) 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.

(B) 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.

(C) 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.

(D) 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.

(E) 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.

考点:比较（Comparison）简洁有效（Rhetorical Construction）

1)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

2)比较的双方必须概念对等

(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,意思清晰,结构简单

(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

(C)去掉插入语with more than 300…原句变成Siberia’s Lake Baikal it holds 20 percent… it多余.

后半句结构混乱.

(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,应该是Baikal的水量和五大湖的水量进行比

较.

句子结构: More than 300 rivers drain..., which holds… fresh water, more than…

我不太明白的是，D中的which为什么不可以跳跃指代20 percent？
还有，这个which加不加和同位语我觉得是一样的啊，那个最后个同位语不就是省略了which is 吗？

请解答

which指代20 percent：20 percent is more than all the North American Great Lakes combined.百分数和五大湖比？即使是20 percent of water，也不能more than the lakes，应该是more than 五大湖的水量。A项句子表达的意思是这样的，Siberia's Lake Baikal holds （water）more than all the North American Great Lakes combined hold.

这样说来A不是也错了？

没有错，只不过是比较句中的省略。

D中，while得用法不当。

其实我还是不明白的~
注解说A:more than all the…作为20 percent of the world’s fresh water的同位语,意思清晰,结构简单。那么lake和water怎么比？

我又琢磨了很久，现在说说我自己的意见：
非限定定语从句which holds…就近修饰Lake Baikal。
more than all the North American Great Lakes combined.概括的是Lake Baikal holds 20 percent of the world's fresh water整句话。因为用抽象性名词充当同位语概括前句内容使用这种句型，要求抽象性名词既可以概括前句内容，又可以充当从句的修饰对象。这样比较对象也是平行了的。

大家指教。

D 中which 指代 20 percent of world's fresh water. 既不单指world's fresh water, 也不单指20 percent. 因为20 percent of 是 world's fresh water 的mission-critical类型的定语，当做先行词时与名词是一体的。
eg. an ice sheet covers [80 percent of the surface of Greenland], which is roughly the size of Alaska.
D错在While的用法

A的more than all那句的确是同位语，不是修饰之前整个句子，只修饰20 percent of world's fresh water。同位语是修饰NOUN的从句。
