1，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）
(E) and merges the nuclei of atoms, unlike atomic reactors that split them apart
这种题目我上次问过，但是好像还是不太懂，为什么C 不可以，按照我看OG做这种题的做法，它划线句之前已经有个and hydrogen bombs，不是等于收尾了吗？为什么还是需要一个and？而且为什么是用like呢？

The Iroquois were primarily planters, but supplementing their cultivation of maize, squash, and beans with fishing and hunting.
(A) but supplementing
(B) and had supplemented
(C) and even though they supplemented
(D) although they supplemented（D）
(E) but with supplementing
这题我是做出来的，但其实意思一直不太了解，谁能帮我解释一下吗，这句句子是不是可以按照这个顺序来理解：Although they supplemented their cultivation of maize, squash, and beans with fishing and hunting，the Iroquois were primarily planters.我按照这个顺序来理解，对吗

第一题，C中 as nuclear reactors do 有歧义
像nuclear reactor do的是merging 还是 splitting不清楚
是不好的表达
