Your Internet experience will be influenced, when the net speed is too slow-it takes so long to open a web page and the reality show you are watching stops every few minutes. That can be very unpleasant. But it could be a thing of the past after 5G networks fully arrive.
The "G" stands for the "generation" of your mobile network. 1G let us talk to each other, 2G let us send messages, 3G gave us mobile data (数据) and the Internet, and 4G made all of these things faster. About 100 times faster than 4G networks, 5G will let people enjoy a faster Internet speed than ever before. This means that you will be able to download (下载) an HD movie in seconds with a short delay (延迟). But 5G won't just bring faster mobile Internet. People can use it for many other things as well.
With a 5G network, the short delay in information exchange will allow driverless cars to run more safely, as they will be able to communicate in real time and avoid unexpected dangers. At the same time, 5G -enabled wearable devices (设备) will keep doctors know what is happening to their patients and let them know in time if there is something wrong. Besides, VR games will become more popular with 5G. The short delay of 5G will make the games feel even more real.
According to BBC, though 5G will make our lives more convenient, it will not be perfect. For one thing, 5G will not travel "far". On 4G networks, you can be 10 kilometers away from the nearest transmission base (传输基站) and seldom lose signal (信号). But 5G will only cover about 300 meters, meaning that we will need more transmitters so that we can get signals. And in order to use 5G, we will have to buy new products exactly made for 5G that are expensive now.

Some of you may play Ant Forest. It is a game on Ali pay. Users collect "energy" to make their "trees" grow. When the "energy" reaches a certain level (程度), some organizations and companies will plant a real tree in a desert area of China. And now it seems that the country's efforts as a whole to make a greener world have paid off.
According to a study by NASA, China and India are the main reasons for making the Earth greener over the past twenty years. The study has found that since 2000 the Earth's green leaf area has increased by 5 percent, or over 5 million square kilometers. The increased green leaf area is as large as that of the Amazon rainforest. It is mainly the result of big trees-planting programs in China and intensive agriculture (集约型农业) in both countries, according to NASA. China and India take up one third of the increased greening, but is only 9 percent of the planet's land area covered in vegetation.
China played the most important role in the increase of the green land, adding 25 percent to this increase, while India added 6.8 percent. Over the past years, China has made great efforts to green the land. In 1978, China began a nation-wide forestation project–the Three North Shelterbelt Forest Program, also known as the" Great Green Wall". The program has seen many trees planted in 13 provinces and autonomous regions such as Tibet and Inner Mongolia in northern China to act as windbreak. By the end of 2017, the forest coverage rate among the areas of the project had reached 13.57 percent, compared to 5.05 percent 40 years ago.
Because of China's success in dealing with desertification (沙漠化), the United Nations Environment Program (UNEP) believes the country is a good example for others to follow. China is one of the most successful countries in greening the desert and has lessons to share with the world.
