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(C)

like表示一种similarity，一般是两种不同的东西本质上存在相似性，比如he acts like a fool，he和fool之间存在一种相似性，但he本身不是fool。 as可以表示行为、动作等的相似性。 这里the force powers*****与nuclear reactor的工作原理相似，是行为与动作之间的比较。你不能说Nuclear fusion 或force像nuclear reactors，因为nuclear reactors本身就是利用率nuclear fusion的原理
OG 11 122 More than 30 years ago Dr. Barbara McClintock, the Nobel Prize winner, reported that genes can "jump," as pearls moving mysteriously from one necklace to another.
(A) as pearls moving mysteriously from one necklace to another
(B) like pearls moving mysteriously from one necklace to another
(C) as pearls do that move mysteriously from one necklace to others
(D) like pearls do that move mysteriously from one necklace to others
(E) as do pearls that move mysteriously from one necklace to some other one
as 表示行为，动作上的像，而我认这题很符合，因为，不能说pearls像 genes，而是 genes jump与pearls move...像，所以应该用as
