寫(xiě)作構(gòu)思
核能的利用與開(kāi)發(fā)是當(dāng)下的一個(gè)熱門(mén)話(huà)題。本題在一開(kāi)始就介紹了有關(guān)核能的眾所周知的危險(xiǎn)和益處，這些觀點(diǎn)都有道理，也都是有據(jù)可查的。因此，對(duì)于這樣的一個(gè)題目，我們的態(tài)度可以是如下兩種：一種是認(rèn)為核能的優(yōu)點(diǎn)很多，雖然有危險(xiǎn)，但可以控制;另一種是認(rèn)為雖然核能有優(yōu)點(diǎn)，但會(huì)給人類(lèi)造成巨大的威脅，因此最好不再利用。不管采取哪種觀點(diǎn)，我們都最好加入讓步段，這樣會(huì)使觀點(diǎn)看起來(lái)更為全面，畢竟，談核能的優(yōu)點(diǎn)而對(duì)危險(xiǎn)避而不談，或是談危險(xiǎn)而忽視它的優(yōu)點(diǎn)都是不可取的。

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.
