We have been living in the nuclear age for over half a century. Since the ﬁrst atomic bombs were developed, nuclear technology has provided governments with the ability to totally destroy the planet. Yet technology has been put into positive use as an energy source and in certain areas of medicine. Is nuclear technology a danger to life on Earth? What are beneﬁts and risks associated with its use? Write an essay of about 400 words. You should supply an appropriate title for your essay.

Nuclear Technology: Beneﬁcial or Disastrous?
One question that has caused a great deal of controversy over the years is nuclear technology. Although it offers a number of advantages in world peace and green power, it is also a dangerous technology. Nuclear weapons pose the greatest threat to life. Even the use of nuclear technology for peaceful purposes also carries some serious risks. In this essay, however, I intend to show how the beneﬁts of such technology counterbalance its disadvantages.
The opponents of nuclear power generally base their arguments on the danger it presents to the world. There are two main dangers: the risk of nuclear warfare and the nuclear disasters. The danger of nuclear war is obvious and if one thinks about Chernobyl, it is easy to understand why people are worried about nuclear power, as it can cause major suffering.
There are, however, good reasons for believing that nuclear technology is generally advantageous. The first of these is that there has not been a major world conflict since the invention of nuclear weapons. Although nuclear weapons have enlarged the mechanism of war by threatening to kill more people more secretly and more horribly than those of the past, it is generally agreed that such weapons should be the last thing to be thought of as a means to win a war because there would be no winner in any nuclear conflict. If anything goes wrong, the scale of destruction on human lives and civilization is beyond imagination. The nightmare of Hiroshima is a vivid memory, so nuclear weapons hidden in stock somewhere serve to maintain world peace by theory of counter-attack .
The other most significant benefit relates to the environment. Perhaps the greatest danger facing our world today is a combination of global warming and the greenhouse effect. This danger is caused partly by burning fossil fuel, which leads to our polluted atmosphere. Nuclear power, however, is a much greener alternative which does not have such negative effects.
Already power plants have been in operation in a number of countries. These are successful examples to be followed. All in all, although it is true that nuclear weapons pose the greatest threat to life, the use of nuclear technology for peaceful purposes is really beneﬁ cial. In all appearances, the fear of war is overcome by the need for economic development.
counterbalance ：抵消 ，使平衡
the scale of destruction ：破坏的范围
in operation ：工作 中，运转着

本句的长度是考生作文中难得一见的。本句的主干为让步状语从句，其从句部分包含了并列结构和比较结构，而主句部分则包含了主语从句和原因状语从句。本句不仅句式复杂 ，而且还在句末使用了虚拟语气“because there would be no winner in any nuclear conflict”，说明了爆发核战争的不可能性。本句句意为：虽然核武器 由于比以前的武器能更秘密地、更恐怖地杀死更多的人而扩大了战争机制，但人们普遍赞同这样一个观点，那就是这样的武器应该是最不应该用来赢得战争的，因为在任何核冲突中都没有赢家。
