标题: prep2012 - sc65求大牛解答！！！！
In order to conserve the energy and heat they need to spend the entire winter sitting motionless over
incubating eggs, male emperor penguins huddle over the nests in groups, thereby reducing the rate at
which they burn energy so that it is 25 percent lower than it would be for isolated birds.
A. thereby reducing the rate at which they burn energy so that it is 25 percent lower than it would be for
B. thereby reducing their rate of burning energy it is 25 percent lower when compared with
C. and they thereby reduce by 25 percent the rate they burn energy, as compared to what it would be
with
D. which thereby reduces by 25 percent their rate of burning energy, when comparing them to
E. which thereby reduces the rate they burn energy so that it is 25 percent lower than

答案是A，没有异议。最后是独立主格结构作状语表示结果。我对it的用法有点疑问：lower than it would be for isolated birds。it 作为代词的时候，不是只能代替前面事物的本身么？如果要指代同类不同一的事物，应该用的是that吧。我就因为这个原因把A给排掉了。求牛牛解答？

it 指代的是the rate
the rate 这个东西本身并没有变并没有指向另一种生物的rate(那样的情况需要用that of 新生物)
这里还是指[企鹅燃烧能量的]rate
只不过the rate 前后的具体数值变化了而已
用it 没什么问题
再者 5个选项都用的是it 没有用过 that, 楼主根据什么排除掉的A....

个人见解供参考哈

it is 25 percent lower than it would be for isolated birds 我知道前面那个it是指企鹅燃烧能量的rate，但是后面那个it不应该代指isolated birds燃烧能量的rate么？两个rate是同一类的但指的不是同一个东西。在这里that会不会更好一点呢？

最后是不是独立主格结构作状语表示结果，是doing sth做状语，表结果。
觉得it指代的是同类同物，但是是实际情况和一个虚拟情况的比较，但比较的肯定是同一个东西。
你想想：
学MBA的我（现实）和要饭的我（虚拟），是不是同一个我呢？

明白了。it would be...是虚拟语境，看的时候忽略了would的时态，罪过罪过
