Mark Twain once said that everyone talks about the weather, but no one ever does anything about it. This was true in his day. But it may not be the cave in today’s world. In fact, humans have found many different ways to control the weather.
Cloud seeding(云催化) is a kind of technology that can control rain. It is done by spreading chemicals like dry ice or silver iodide(碘化银) inside of clouds, either by rocket or airplane. This changes water content inside the cloud, which helps to control the rainfall, the time and even the place where it rains.
This technology has helped to solve natural disasters, such as droughts(干旱). It has also played a key role during important events. For example, China used cloud seeding in Beijing just before the 2008 Olympic Games in order to stop rain from falling during the event.
Cloud seeding has been put into use for some time, however, some scientists are still wondering whether this technology is safe. On one hand, it is believed that it might have side effects(副作用). For example, silver iodide may be bad for the environment. On the other hand, no two clouds are the same, so every new experiment introduces new conditions.
In addition to controlling rain, scientists have also tried to find ways to weaken storms and hurricanes. Scientists at the US National Hurricane Centre Headquarters think it might be possible to control hurricanes by using lasers(激光). Others believe that burning rock oil in a hurricane’s path could slow the storms down.

As we know, the time of 5G technology (技术) is coming. Recently, there’s a lot of information about 5G. But what is this technology and how might it bring to our lives?
What is 5G?
5G means the fifth generation mobile networks (网络), a better technology than 4G. And we know, 4G comes after 3G and makes the network run faster than 3G.
When will 5G come to our life?
Before we can all use 5G, there must be a new system (系统) for 5G to work. In the USA, some cities will first use 5G this year. Experts say it will take a few more years or even longer to reach every place. In China, a few cities are using 5G now. And more and more cities will join this group. Next year, 5G will become national, even in the countryside.
What can 5G do?
Experts say 5G will help to build future“smart cities ” with the help of sensor networks (传感器网络). Such networks will be able to help the police with the traffic. They can help us know what’s happening in our homes when we are at work. They can even help to make it possible for doctors to perform an operation (手术) far away.
?
In the future, more information and more kinds of information will be travelling across 5G networks. Much of the information could be about persons, businesses or government organization (政府组织). So we can see, the wider use of a 5G network means any mistake of the system would cause serious results. Then they may bring problems of public security(安全) and world economic (经济) activity.
