Science and technology have been bringing human beings tremendous benefits. Thanks to science and technology, we now live comfortably and conveniently in houses furnished with air conditioners, refrigerators, washing machines and televisions etc. Thanks to science and technology, we can eat fresh vegetables at the year round. Thanks to science and technology, we can travel long distances in the fraction of a second on planes, trains and cars. Thanks to science and technology, we wear clothes with synthetic materials which can not easily be worn out.
科技已经给人类带来了巨大的益处。由于科技，我们现在能够生活在舒适、方便配有空调、冰箱、洗衣机和电视机等的房子。由于科技，我们可以全年都吃新鲜的蔬菜。由于科技，我们可以在不到一秒中在飞机、火车和汽车上实现远距离旅行。由于科技，我们穿的含有合成材料的衣服才可以不易被磨损。
However, science and technology have atso brought us a lot of disasters. First, because of the many breakthroughs in the field of medicine, people are now living much longer than they used to. As a result, the population of the world is increasing, causing lots of problems. Second, because of the development of industry, lots of the wastes from factories pour into the air and rivers, causing pollution of all kinds. Third, some terrorists are using science and technology against mankind. They use biological, chemical and unclear weapons to threaten world peace...
然而,科技也给我们带来了许多的灾害。首先,由于医学领域上的许多突破，人们现在的寿命要比以前更长。因此,世界人口正在不断增长，导致大量的问题。第二，由于工业的发展,大量的工厂废弃物的涌入空气和河流中，造成各种各样的污染。第三,一些恐怖分子正在利用科技对抗人类。他们利用生物、化学和核武器威胁世界和平…
So it's urgent that we find ways to solve these problems. But we should not stop the development of science and technology because of these disasters they bring, just as we should not give up eating for fear of choking. In addition, we should make some rules to regulate our actions. As long as we use science and technology in a proper way, they may bring us even more benefits.
所以，寻找解决这些问题的方法是迫在眉睫的。但是我们不应该停止科技的发展,因为他们所带来的这些灾难，正如我们不应该因噎废食一样。此外,我们应该制定一些规则来规范我们的行为。只要我们正确使用科技，他们可能会给我们带来更多的好处。
