　　在科学技术的帮助下，我们人类现在过着比以往更幸福的生活。以电脑发明为例，它不仅帮助我们解决数学难题来节约时间，而且你也能把材料或信息输进电脑通过网络与你的生意伙伴进行交流。另外它可以在程序员的操作下取代我们处理很危险的工作。在某种程度上，他们的优势超过人类的优势，这就是为什么人们创造一些有人工智能的机器人来帮助我们人类的原因。

　　然而，一些人担忧在高科技的滥用中会出现危险的问题。就我个人而言，我不同意这点。不管怎样，这些技术可以弥补我们的不足并且帮我们做很多事情。如果不是这样的话，我们为什么要创造和发展它们呢？ ______________________________________________________________________________________________________ 答案：

　　With the help of science and technology, we human race are now living a much happier life than before. Take the invention of the computer for example, it not only helps us solve difficult mathematical problems to save time, but you can also type any material or information into your computer to communicate with your teammates on your business by the network. Besides, it can take the place of us to deal with many dangerous situations under the control of the programmers. In a way, their advantages are over humans，, and this is why people create some robots with artificial intelligence to help us human beings.

　　However, some people are worried that dangerous problems will arise from any over-usage of high-tech. Personally speaking, I disagree with it. Anyhow, the technology can make up our shortcomings and help us do lots of things.
