参考译文3:一个普遍的误解是核聚变能源取之不尽，理由是海洋中蕴含着不可计量的氘。
氘dāo氢的同位素之一，符号D（deuterium）或21H。原子核中有一个质子和一个中子，普通的氢中含有0.02%的氘。用于热核反应。也叫重氢。（巧记：deuterium丢tear rium)。氘（dāo与刀同音）；重氢(氢的同位素)heavy hydrogen。

翻译句子段落扩展阅读
It is a popular misconception that nuclear fusion power is free of radioactivity; in fact, the deuterium-tritium reaction that nuclear scientists are currently exploring with such zeal produces both alpha particles and neutrons.(The neutrons are used to produce tritium from a lithium blanket surrounding the reactor.)一个广为流传的误解，是核聚变能源不具备放射性;实际上，当下核科学的热门研究领域氘氚反应，会同时释放阿尔法粒子和中子(中子来自于包裹核反应堆的锂层，用于制取氘)。
Another common misconception is that nuclear fusion power is a virtually unlimited source of energy because of the enormous quantity of deuterium in the sea.另一个普遍的误解是核聚变能源取之不尽，理由是海洋中蕴含着不可计量的氘。
Actually, its limits are set by the amount of available lithium, which is about as plentiful as uranium in the Earth‘s crust.实际上，限制在于我们能获得多少锂，锂的含量大致与地壳中的铀含量相当。
Research should certainly continue on controlled nuclear fusion, but no energy program should be premised on its existence until it has proven practical. (122 words) 关于可控核聚变的研究当然该继续，但任何能源项目在证实可实际操作前，都不该仓促上马。（直译是，……没有证明核能项目安全可行之前，任何项目都不该假设它存在。）
(premise 此句中做 postulate “假设”解释。
practical 切合实际的，此句中可以意译地理解为“安全可行的”。

GMAT阅读作业练习题
It is a popular misconception that nuclear fusion power is free of radioactivity; in fact, the deuterium-tritium reaction that nuclear scientists are currently exploring with such zeal produces both alpha particles and neutrons. (The neutrons are used to produce tritium from a lithium blanket surrounding the reactor.) Another common misconception is that nuclear fusion power is a virtually unlimited source of energy because of the enormous quantity of deuterium in the sea. Actually, its limits are set by the amount of available lithium, which is about as plentiful as uranium in the Earth's crust. Research should certainly continue on controlled nuclear fusion, but no energy program should be premised on its existence until it has proven practical. For the immediate future, we must continue to use hydroelectric power, nuclear fission, and fossil fuels to meet our energy needs. The energy sources already in major use are in major use for good reason.
fusion聚变 VS fission 裂变

(A) criticize scientists who believe that the deuterium-tritium fusion reaction can be made feasible as an energy source
(B) admonish scientists who have failed to correctly calculate the amount of lithium available for use in nuclear fusion reactors (C) defend the continued short-term use of fossil fuels as a major energy source
(D) caution against uncritical embrace of nuclear fusion power as a major energy source (D )
(E) correct the misconception that nuclear fusion power is entirely free of radioactivity
25. It can be inferred from the passage that the author believes which of the following is about the current state of public awareness concerning nuclear fusion power?
(A) The public has been deliberately misinformed about the advantages and disadvantages of nuclear fusion power.
(B) The public is unaware of the principal advantage of nuclear fusion over nuclear fission as an energy source.
(C) The public's awareness of the scientific facts concerning nuclear fusion power is somewhat distorted and incomplete.（C）
(D) The public is not interested in increasing its awareness of the advantages and disadvantages of nuclear fusion power.
(E) The public is aware of the disadvantages of nuclear fusion power but not of its advantages.
26. The passage provides information that would answer which of the following questions?
(A) What is likely to be the principal source of deuterium for nuclear fusion power? （A）
(B) How much incidental radiation is produced in the deuterium tritium fusion reaction?
(C) Why are scientists exploring the deuterium-tritium fusion reaction with such zeal?
(D) Why must the tritium for nuclear fusion be synthesized from lithium?
(E) Why does the deuterium-tritium reaction yield both alpha particles and neutrons?
27. Which of the following statements concerning nuclear scientists is most directly suggested in the passage?
(A) Nuclear scientists are not themselves aware of all of the facts surrounding the deuterium-tritium fusion reaction.
(B) Nuclear scientists exploring the deuterium-tritium reaction have overlooked key facts in their eagerness to prove nuclear fusion practical. (C) Nuclear scientists may have overestimated the amount of lithium actually available in the Earth's crust.
(D) Nuclear scientists have not been entirely dispassionate in their investigation of the deuterium-tritium reaction. (D)
(E) Nuclear scientists have insufficiently investigated the lithium-to-tritium reaction in nuclear fusion.
