大全541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
答案给的是E。我这题也做糊涂了,现在也没完全懂,尽自己的一点微薄之力给大家提供一些信息,所以新立了一个帖子,希望对以后的讨论由帮助。
现在试着翻译一下:
Nuclear fusion is the force that powers the Sun, the stars, and hydrogen bombs, and merges the nuclei of atoms, unlike atomic reactors that split them apart.(E)核聚变是一股力量,这种力量为太阳、星辰、氢弹供给能量,并将原子核合并,而不是像反应堆那样将它们分离。
相关知识连接:核聚变(Nuclear fusion )是一种还未被人类完全掌控的核反应,人们现在还不能控制它的反应速度,所以也不能把它用于民用设施。题中提到的反应堆(atomic reactors )利用的是核裂变,这种反应已经被人类摸透。现在所有的核电站利用的都是核裂变。和化学能不同的是,这两种力量都来原自原子的变化。E=mc2,可能很多人都对这个公式有印象(总之就是说物质质量变化时,会放出能量。不敢再扯远)
再说回来,我当时没有选E,是因为,我认为merge和power不是并列的关系,题中的merging是想说明这种伴随状态。而且从现实中说,这种force是来源于merge,而不是现有force然后造成merge;相反,太阳星辰的生生不息倒是这种merge的结果。
我这么做题是挺违反白痴原则的,写出来主要是为了让大家进一步讨论。希望NN门继续不吝赐教!谢谢!
