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.) 抱歉下划线不知为何加不了,就用括号代替了
b) merging the nuclei of atoms instead of splitting them apart, like nclear reators c) merging the nuclei of atoms rather than splitting them apart, as nuclear reactors do
我觉得b也没错,og的解释说:here the basis of comparison is unclear, and the usage is incorrect。对此非常不解,请高手指教!
