Third, some terrorists are using science and technology against mankind. They use biological, chemical and unclear weapons to threaten world peace...
So its 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.
作为一个结果，世界人口的增长，造成小孩的问题。其次，由于工业的发展，大量的工业废弃物倒入空气和河流，造成污染的各种属性。第三，一些恐怖分子利用科学技术对人类。他们使用生物、化学和不明武器威胁世界和平
因此，我们迫切需要找到解决这些问题的方法。但是我们不应该因为这些灾难而停止发展科学技术，正如我们不应该因为害怕窒息而放弃吃东西一样。此外，我们应该制定一些规则来规范我们的行为。只要我们用科学和技术，他们可以给我们带来更多的好处。
