In the contemporary world, with the development of science and technology, all aspects of human technology are

becoming increasingly advanced. A host of countries or regions are increasing their investment in robots.

As a coin has two sides. While robots bring us benefits, they also bring us some problems. On the one hand, they can help humans to complete some dangerous tasks. For example, they can put out fires in dangerous environments, spy on situation in wars and so on. On the other hand, they will know a lot of our privacy, consume more electricity and even threaten our existence.

I, as a college student, am convinced that it is significant for humans to research and develop robots. There is no doubt that if we can use robots rationally, our life will be better and better.

在当今世界，随着科学技术的发展，人类各个方面的技术都变得越来越先进。许多国家或地区正在增加对机器人的投资。

事物都有两面性。当机器人给我们带来好处的同时，他们也给我们带来了一些问题。一方面，它们可以帮助人类完成一些危险的任务。例如，他们可以扑灭火灾 在危险的环境，侦察情况 在战争中等。另一方面，他

们会知道很多我们的隐私、消耗更多的电力甚至威胁我们的生存。

作为一名大学生，我相信这是很重要的 对于人类去研究和发展机器人。毫无疑问，如果我们能合理地使用机器人，我们的生活会越来越好。

5G技术是今年的热门话题。在我看来，它的主要特点是它使网络速度非常快。5G比4G快10倍以上。这极大地满足了人们对网速的要求。而且，更重要的是 5G技术的应用将极大地促进国家经济的发展。但是，如果我们处理不好，这可能会导致更严重的网络攻击。

作为一名大学生，我相信研究和开发5G技术对人类来说是很重要的。毫无疑问，如果我们能够正确地使用5G技术，我们的生活会越来越好。

In the contemporary world, with the development of science and technology, all aspects of human technology are becoming increasingly advanced. A host of countries or regions are increasing their investment in AI.

AI stands for “artificial Intelligence”. In the past decade, the field of artificial intelligence has developed rapidly. Of course, in the future, artificial intelligence will also play an increasingly important role in the development of science and technology. However, every coin has two sides, artificial intelligence is no exception. On the one hand, artificial intelligence has brought us a lot of convenience. For example, the products replace humans to do housework and help human to learn and so on. On the other hand, it may make people more and more lazy.

I, as a college student, deem that it is significant for humans to develop AI. Without doubt if we can use AI rationally, our life will be better and better.

在当今世界，随着科学技术的发展，人类各个方面的技术都变得越来越先进。许多国家或地区都在增加对人工智能的投资。

AI代表“人工智能”。在过去的十年里，人工智能领域发展迅速。当然，在未来，人工智能也将在科学技术的发展中发挥越来越重要的作用。然而，任何事物都有两面性，人工智能也不例外。一方面，人工智能给我们带来了很多方便。例如，产品代替人类做家务，帮助人类学习等等。另一方面，这可能使人们越来越懒惰。

作为一名大学生，我认为研究和开发人工智能对人类来说是很重要的。毫无疑问，如果我们能合理地使用人工智能，我们的生活会越来越好。

In the contemporary world, with the development of science and technology, human network technology is becoming increasingly advanced. At the same time, it also brings some problems, such as information security.

In recent years, information security has also become a hot topic. There are a host of information leaks every year. We don’t feel it, but it affect us, for example, we often receive some junk messages. Therefore, while enjoying the benefits of the network, we should also pay attention to information security and strengthen prevention. By doing so, we can have a more security network environment.

I, as a college student, deem that it is significant for people to strengthen the management of information. There is no doubt that if we can use Internet rationally, our life will be better and better.

在当今世界，随着科学技术的发展，人类网络技术越来越先进。同时也带来了信息安全等问题。

近年来，信息安全也成为一个热门话题。每年都有大量的信息泄露。我们感觉不到它，但它影响我们，例如，我们经常收到一些垃圾信息。因此，在享受网络带来的好处的同时，我们也要重视信息安全，加强防范。通过这样做，我们可以有一个更安全的网络环境。

作为一名大学生，我认为加强信息管理是很重要的。毫无疑问，如果我们能合理使用互联网，我们的生活会越来越好。

In the contemporary world, with the development of science and technology, all aspects of human technology are becoming increasingly advanced. A host of countries or regions are increasing their investment in EV.

EV stands for “Electric Vehicle” .In the past decade, the field of petrol cars have developed rapidly. However, in recent years, the problem of air pollution is becoming more and more serious. In the future, electric cars may replace petrol cars. It would not only reduce petrol consumption, but also reduce greenhouse gas emissions. EV is very environmental friendly vehicle.

I, as a college student, deem that EV will have a promising future and its appearance will greatly reduce environment pollution. There is no doubt that EV will make our life better and better.

在当今世界，随着科学技术的发展，人类各个方面的技术都变得越来越先进。许多国家或地区正在加大对电动汽车的投资。

EV代表“电动汽车”。在过去的十年里，汽油汽车领域发展迅速。然而，近年来，空气污染的问题变得越来越严重。在未来，电动汽车可能会取代汽油汽车。它不仅能减少汽油的消耗，还能减少温室气体的排放。电动车是非常环保的汽车。

作为一名大学生，我认为电动车将有一个很好的未来，它的出现将大大减少环境污染。毫无疑问，电动汽车将使我们的生活越来越好。

In the contemporary world, with the development of science and technology, all aspects of human technology are becoming increasingly advanced. At the same time, there are a host of business models, such as the utility storage.

First of all, utility storage is a service pattern in which providers provide storage capacity to individuals, organizations or enterprises unit for use on a per-use basis. Second, the purpose of utility storage is to use resources efficiently and to reduce costs. Most importantly, there are three basic modes of utility storage, which greatly improve user satisfaction. Now in China, both Alibaba and Tencent are increasing their investments in this area.
