   Today, mankind has made great progress and achievements in modern science and technology. It makes our live more convenient, comfortable and beautiful and our work relaxed and efficient. However any science and technology is a double – edged sword with both advantages and disadvantages. For example, automation technology and intelligent robot technology can help humans to do a lot of work, but will cause the deterioration of human physical strength and intelligence. Nuclear power generation technology can provide mankind with a huge amount of energy, but it is difficult to deal with nuclear waste, which will pollute the environment. Nuclear weapons also makes the earth and mankind face a  serious crisis of devastating nuclear war. Modern biotechnology can reveal the secrets of life and prevent various diseases, but the abuse of biotechnology may also pose new threats to human beings, such as biological weapons, genetically modified food, artificial bioethics crisis and high-risk microbes infectious diseases and so on. Modern chemical polymer synthesis technology has provided mankind with many new materials with wide applications, but the waste materials which are difficult to decompose also pose a serious threat to the natural environment and human health.  Remote sensing and remote control technologies in space help humans explore the universe, predict weather changes and natural disasters, but their military use poses great risks to humans.

   In a word, any modern science and technology has both advantages and disadvavtages. Human beings must best use the advantages of modern science and technology to limit or put an end to the disadvantages. Only有 in this way can modern science and technology truly benefit human beings and all of us are safe. Otherwise, science and technology will bring disaster. 

   当今，人类现代科学技术已经取得了巨大进步和成就,现代科技使我们的生活更加方便舒适美好，使我们的工作更加轻松高效。但是，任何科学技术都是一把双刃剑，既有对人类有利的优点，也有对人类不利的缺点。比如，自动化技术和智能机器人技术，可以帮助人类完成很多工作，但是会导致人类体力和智力的退化。核发电技术可以给人类提供的巨大能源，但是核废料很难处理会污染环境，核武器还使地球和人类面临毁灭性核战争的严重危机。现代生物技术可以揭示生命的奥秘，防止各种疾病，但是生物技术滥用也可能给人类造成新的威胁，如生化武器、转基因食品、人造生命伦理危机、高危险性微生物传染病等。现代化学高分子合成技术给人类提供了许多用途广泛的新材料，但是难分解的高分子材料废物也对自然环境和人体健康造成严重威胁。航天遥感遥控技术帮助人类探索宇宙，预报天气变化和自然灾害，但是这些技术用于军事会对人类造成极大风险。

   总之 任何现代科学技术都具有优点和缺点两面性，人类必须尽可能地运用现代科学技术的优点，限制或杜绝现代科学技术的缺点，只有这样，现代科学技术才能真正地有利于人类，我们所有人才是安全的。否则，科学技术就会给全人类带来灾难。
