又一个语法考点的总结（现在分词伴随状语的正反向考法）

supermary

Nuclear fusion is the force that powers the Sun, the stars, and hydrogen bombs, merging the nuclei of atoms and not splitting them apart, as in nuclear reactors.

C) merging the nuclei of atoms rather than splitting them apart, as nuclear reactors do
(E) and merges the nuclei of atoms, unlike atomic reactors that split them apart

我觉得这道题如果琢磨：是nuclear fusinon merges nuclei of atoms,还是the force that powers and merges nuclei of atoms比较花时间，似乎原子核融合是原子的核心的整合；原子核融合是一种力量，力量似乎也能使原子的核心整合，对文科背景的人就更加难以一步到位。

However,从分句本身的结构可以比较快的下手。
C）提出是merge the nuclei of atoms,而不是分裂他们，动作对比强烈，重点强调merge;
E) 而不象分裂“他们的”automic reactors一样；象atomic reactors什么？是不象他们的分裂呢还是其他方面？这里的限制性从句让“不象”的内容产生了歧义。
我觉得OG里的题目还是比较仁慈的，如果这路不通，总会还有其他的路让你走走。

以下是引用dancingforum在2004-5-1 3:01:00的发言：

版主总结的真的很好， 但是我还是不太明白， 有点似懂非懂：
  

--------------------------------------------------------------------------------------------------------------------------------------------来一个实际中的例子，新东方补充教材新版本204题：

Nuclear fusion is the force that powers the Sun, the stars, and hydrogen bombs, merging the nuclei of atoms and not splitting them apart, as in nuclear reactors.

(A) merging the nuclei of atoms and not splitting them apart, as in nuclear reactors

(B) merging the nuclei of atoms instead of splitting them apart, like nuclear reactors

(C) merging the nuclei of atoms rather than splitting them apart, as nuclear reactors do

(D) and merges the nuclei of atoms but does not split them apart, as is done in unclear reactors

(E) and merges the nuclei of atoms, unlike atomic reactors that split them apart

很明显，is这个动作和merge这个动作不可能是同时发生的，也不可能是前一个句子的整体导致后面动作的发生，所以使用merge就错了。大家可以注意到，ABC三个选项都在引诱你使用伴随状语，这就是ETS的险恶用心。所以答案必须在DE中筛选。

--------------------------------------------------------------------------------------------------------------------------------------------

从语法点上看， 分词的主要功能就是做形容词修饰名词或代词，我不觉得应该把merging看成和 is 并列构成伴随状语(版主用来排除ABC的主要依据），这题为什么不可以 将 merging 看成是修饰主句的主语 fusion 呢， 如果我们把语序稍微调整一下， 变成：

Merging the .....,  nuclear fusion is a force that ......

把merging看成方式状语， 觉得有什么问题呢？

一直觉得分词做状语在GMAT里挺浑人的，但我手边没有语法书， 能不能请版主把分词的用法给来个详细的， 全面的总结.  谢谢了

另外， 这题到底是 的 D 还是 E 呀， 给我自己选， 我肯定象版主说的，掉坑里，选个 C 了， 呵呵

这道题目再og11-104种的答案是C不是E OR D

解释如下：

C rather than is a correct idiom for comparion in this sentence; as is followed by a clause with a subject, nuclear reactors, and a verb, do; the comparison is clear and complete.

D Illogical and awkward construction attempts to make merges the second verb of the restrictive clause paralled to powers and does not split; punctuation makes clear this separate action can not be the case;as  is done is awkard and wordy

E Illogical and awkward construction attempts to make merges the second verb of the restrictive clause paralled to powers and does not split; punctuation makes clear this separate action can not be the case;as  is done is awkard and wordy; comparision is awkardly drawn; switch from unclear to atomic is unexplained and unsupported

 本来看了lz的解释恍然开朗，在一看og的选向，彻底迷糊了。。。可是这可是og11版的解释和答案，应该不会有错吧。

 

 

OG11-- 104不是这道题啊?  彻底晕了!!!

还是觉得应该以OG为准吧

估计出题的人自己也没有考虑到两个过程是不是同时发生的这样一个问题，从语感角度而言我也会选c：）

一家之言，仅供参考

Amethyst69

同意楼上的，以OG11为准吧。。。

太爱你啦楼主

zhen bang!

倒，支持og的论断，但依然为先前钻牛角，艰难探索语法的NN们致以最强烈的敬意

混乱思维

？可nuclear fusion 那道题的正确答案就是Ｃ呀？！

shawnsea

虽然楼主的总结精神可嘉，不过跟OG的解释和思路不一样。
建议大家以OG的官方解释为准，以免受到误导。


    

104.
        Nuclear
fusion is the force that powers the Sun, the stars, and hydrogen bombs, merging
the nuclei of atoms and not splitting them apart, as in nuclear reactors.

    

(A) merging the nuclei of atoms and not splitting them
apart, as in nuclear reactors

    

(B) merging the nuclei of atoms instead of splitting them
apart, like nuclear reactors

    

(C) merging the nuclei of atoms rather than splitting them
apart, as nuclear reactors do

    

(D) and merges the nuclei of atoms but does not split them
apart, as is done in nuclear reactors

    

(E) and merges the nuclei of atoms, unlike atomic reactors
that split them apart

    

Idiom + Logical predication

    

And not is an awkward way to establish a contrast; instead
of rather than, or unlike are more appropriate idioms to express a
contrast.

    

The comma following bombs is paired with the comma
following apart, and this comma pair sets off the participial phrase
introduced by merging.

    

As introduces a clause; since a clause requires a
subject and a verb, as cannot be followed by the prepositional phrase in
nuclear reactors.

    

A     And not is not
a correct idiom; as should be followed by a clause

    

B      Although like
can grammatically be followed by a noun phrase such as nuclear reactors,
here the basis of comparison is unclear, and the usage is incorrect

    

C    Correct. Rather than is a correct
idiom for comparison in this sentence; as is followed by a clause with a
subject, nuclear reactors, and a verb, do; the comparison is
clear and complete.

    

D     Illogical and
awkward construction attempts to make merges the second verb of the
restrictive clause parallel to powers and does not split-, punctuation
makes clear this separate action cannot be the case; as is done is
awkward and wordy

    

E      Illogical and
awkward construction incorrectly makes merges the second verb of the
restrictive clause and a separate action parallel to powers; comparison
is awkwardly drawn; switch from nuclear to atomic is unexplained and
unsupported

换个思路

如果用D或者E: and merges将在that引导的限定从句中修饰force，而非Nuclear fusion。而本句的意图是比较Nuclear fusion和Nuclear reactors(force和Nuclear reactor比较是不合逻辑的)，因此merge的动作发生者应该是Nuclear fusion. 为了避免歧义，不能用and的连接。
