【正确答案】正确答案： The Challenge of Science on Humanity Science has undoubtedly played a great part in improving our living conditions and making our life more convenient. But science is challenging our humanity as well. As a knife can be used to cut meat or kill people, by the same token, advanced science can be applied for the general benefit of human beings or for the destruction of human nature as well. It is said that the rapid development of telecommunications and internet narrowed the distance of human beings, and thus the world became a global village. But is the distance really narrowed? I don"t think so. The quality family time at the breakfast is shrinking when every family member is busy in checking their Facebook or email as soon as they wake up. More and more people are indulging in the conversation with Siri of their iPhone, while forgetting to give their friends or parents a call. Parents and friends are not the only thing that is replaced by the fancy gadgets. The powerful science seems to enable human beings to do everything. With the help of science, the moon can be landed, the deep ocean exploited, even life can be cloned in the laboratory. So humans simply worship the power of science and worship themselves, but they forget the mightier things in the world, such as love, faith and hope. More precisely speaking, it is not the science that threatens our humanity, since we can"t blame a cell phone or a spacecraft for its anti-human conspiracy. It is the people who are using it that should be responsible for the disappearance of human nature. The science without humanity can do more harm than good to human beings. It is time to think about the challenge we are facing now.
