标题: PREP 77 请教

1、

77. Like any star of similar mass would do,
once the Sun has exhausted the hydrogen in its store, it expands into a red
giant, eventually ejecting its outer envelope of gases to become a white
dwarf.

A. Like any star of similar mass would do, once
the Sun has exhausted the hydrogen in its store, it expands into a red giant,
eventually ejecting

B. Like any star
of similar mass, once the hydrogen in the Sun’s core is exhausted, then it
expands into a red giant and eventually ejects

C. As in the
case of any star of similar mass, once the hydrogen in the Sun’s core is
exhausted, it will expand into a red giant, and eventually ejecting

D. As any star
of similar mass would, once the hydrogen in the Sun’s core is exhausted it will
expand into a red giant and will eventually eject

E.
As would be the case with any star of similar mass, once the Sun exhausts the
hydrogen in its core, it will expand into a red giant and eventually eject

正确选项是E
请问it确实是指代 the Sun 但是后面的句子中的第二个动词为什么不加S呢 it will expand ... and eventually ejects??才对么？

will expand and (will understood) eject...

c d中的时态不一致，对吗？c中exhausted和will expand 不能够一致，所以这一点也不对，是吗？

As would be the case
with any star of similar mass, once the Sun exhausts
the hydrogen in its core, it will expand into a
red giant and eventually eject its outer envelope of gases to become a white dwarf.

once表副词子句, 主要子句
it will expand …and (will) eject…

C选项中的不是exhausted和will expand比较

As
would be the case with any star of similar mass, once the Sun exhausts the
hydrogen in its core, it will expand into a red giant and eventually eject
its outer envelope of gases to become a white dwarf.

另外，想请教一下as跟once是两个连接词，然后再跟一个主要子句，这个的句型很让我疑惑？有这样的吗？

谢谢回复

记得看到过有位NN在帖子提到过 as is the case with 是固定用法的说～～～

我觉得c中的第二个it也不是指代sun的了，而是hydrogen,所以也不对！

作者: sunpaopao 时间: 2007-6-20 05:17
D中的it也不可指代sun

作者: ad264 时间: 2007-6-20 20:51

as is the case with意思我没有问题，请问文法上的解释，在全句中是扮演什么角色？多谢

这道题明显考的就是like和as

like后加与主语对等的名词

as后加句子

这道题光看这一个考点就出答案了，然后还告诉了我们as后可以不加与主句对等的成分，而是加 be case的形式

Like any star of similar mass would do, once the Sun has exhausted the hydrogen in its store, it expands into a red giant, eventually ejecting its outer envelope of gases to become a white dwarf.

A. Like any star of similar mass would do, once the Sun has exhausted the hydrogen in its store, it expands into a red giant, eventually ejecting

Like后不加句子；has时态错；ejecting修饰歧义，修饰sun呢还是修饰giant呢？

B. Like any star of similar mass, once the hydrogen in the Sun’s core is exhausted, then it expands into a red giant and eventually ejects

比较对象不对，star和sun's core比较，错；it无指代

C. As in the case of any star of similar mass, once the hydrogen in the Sun’s core is exhausted, it will expand into a red giant, and eventually ejecting

It指代core，错，应该指代Sun；and前后不平行

D. As any star of similar mass would, once the hydrogen in the Sun’s core is exhausted it will expand into a red giant and will eventually eject

As在这里是作为的意思，不符合逻辑；it无指代；如果是it的话，那后面的expand和eject都应该是单数

E. As would be the case with any star of similar mass, once the Sun exhausts the hydrogen in its core, it will expand into a red giant and eventually eject
