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 unclear reactors

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

选E吧？

C中的最后那个as句子.我觉得有点问题..

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 folloing bombs is paired with the comma following apart, and this comma parir 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.

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.

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.

总结

1. C正确的话，就表明C中的do是指代slipt。也就是do首先指代前面最近的动词形式的原形。

例如：

Fusion, the process that fuels the sun, is the holy grail of nuclear energy. It smashes together atoms to release energy, rather than splitting them apart as modern fission reactors do.（引自网络文章）

2. E错按照OG的说法：(1)merge应该是现在分词作power的伴随，而不是另一个和power平行的动作。(2)unlike作状语放句未，不是ETS喜欢的形式，一般是放句首或是所要修饰的动词的前头。

我个人也觉得c应该是正确的

merge应该是power的伴随状语，用来说明power的
