Your internet experience is ruined( 破 坏 ) when the net speed is too slow – it1 so long to open a web page and the show2you're watching stops every few minutes. That may make you mad. But it could be a thing of the past. 3June 3, 1999, the Ministry of Industry and Information Technology said that China4going to give out licenses for the commercialization (商业化) of 5G.
5G promises much5data download ( 下 载 ) and upload speeds. This means that you will be able to download6 movie in seconds and only experience a short delay ( 延 迟 ) between sending and receiving data. For example, when you have a video chat with your friend, there is generally a 100 to 200 milliseconds ( 毫 秒 ) delay with 4G, but 5G will reduce( 减 少 ) it to 1 millisecond or less, which is almost real time.
With a 5G network, the short delay in information exchange will allow driverless cars to run more safely, 7they will be able to communicate in real time and avoid 8into other cars. At the same time, 5G-enabled wearable devices will keep doctors constantly ( 持续地) updated on the health condition of their patients and the patients can be9 immediately if there's something wrong.
Of course, there are some disadvantages. For one thing, 5G will not "travel" far. On 4G networks, you can be 10 kilometers away from the nearest transmission base (传输基地) . But 5G will only cover about 300 meters. But engineers will never10 solving these problems.
Time is valuable in our life. But how many times have you1, " I can never finish my homework on time! There aren't enough hours in the day!"?
Holly Gabrielle White, a pretty girl who graduated from University of Cambridge, probably disagrees with you! In 2016, White started a channel 2 the video-sharing website You Tube. In her3 , the 22-year-old gets up at 6: 30 am and goes to bed at 10: 30 pm every day. During the day, she balances(使……平衡) studying, cooking, house cleaning and exercising.
A similar case happened to a college student in China. Months ago, the official Tsinghua
University microblog account showed pictures of students' plans, study notes and daily timetable. Among them, a student is very4 in his daily life. He usually goes to bed at 1: 00 am and gets up at 6:00 am. Although he only takes 10 classes a week, the rest of his day will be fully booked. He 5his day by pre-reading his textbooks at 6: 40 am, and ends with a summary of his studies. When he feels like it is hard to stick to his timetable, he writes encouragements to 6, like, "You're the best", and "Go for it"!
Both students' hard work has certainly paid off. White was at the top of her 1527 classmates; and the8 student won a first-class scholarship ( 奖 学 金 ) in Tsinghua University .
The two have9in common. They learn a way of managing time well and efficiently (高效地).White advises to write our tasks in a set order on a to-do list. We should also know how to avoid and release stress because, "Mental health is as10as our physical health."
Indeed, things must be carefully planned before we act, then "twice as much can be accomplished (完成) with half the effort", as the old Chinese saying goes.

Since last December, there have been lots of COVID-19（新冠肺炎） cases both in and out of China. It's not the first time for humans to fight with Viruses. Viruses have brought big trouble to humans, because they may cause widespread disease and death.
What are they? Viruses are considered to be non-living organisms ( 有机物). They can infect animals, plants and humans, making them sick. They have materials like DNA and are protected by a kind of special skin.
Viruses can't reproduce( 繁殖) on their own. Instead, they break in the cells( 细胞) of living organisms to reproduce, spread and take over. But the basic question is, "Where did viruses first come from?" Until now, no clear explanation for this question. "It is difficult to find out where viruses first came from," Ed Rybicki, a virologist at the university of Cape Town in South Africa, told Scientific American, "because viruses don't leave fossils ( 化 石 ) and because it is difficult to study the ways they use to make copies of themselves within the cells they've broken in." Understanding where they came from means fully understanding the history of their hosts( 宿主) – not only humans, but also plants and other animals, which is a difficult task, says Nature.
UK physicist Isaac Newton once said, "Nature is pleased with simplicity and nature is no dummy (傻子)." Indeed, mother nature can provide almost everything humans need if we follow her rules. But if we break the rules, she is likely to be cruel and mad at us. It is believed that the outbreak of COVID-19 is a good example. Humans try to change mother nature. They use more land to make buildings, catch some wild animals to meet their own needs. Humans gradually throw our mother nature out of balance(平衡). For example, cutting a large number of forests leads to global(全球的) warming.
Although we don't know exactly what first caused the COVID-19 outbreak, Brian Lamacraft at Medium said it's time for people to "think carefully about our relationship with our mother nature" and "reconnect with this world and everything that we've been given". After all, according to US poet Gary Snyder, "Nature is not the place to visit. It's our home."

Have you seen some machines called "Little Yellow Dog" that eat rubbish and give some
money to the users? Recently, such machines have at universities in Chongqing. They can turn rubbish into treasure and encourage the public to used things. The machine is as big as a fridge. If the users put an empty bottle in the machine, it will be identified（识别） by small camera. Then it will be put into a built-in bin. The users can get some. They can also give it away.
The machine will tell the company's head office it is filled with bottles. Nearby stations will send workers to have bottles collected. The workers will pack( 打 包 装 )and them to the company.
Now the machinenot only plastic bottles but also other resources. These machines couldencourage the public to protect the environment. People can also see machines in Shanghai in the future. There will be more machines at some large stations, bus stops, neighborhoods and schools. But recycling is not enough, experts say. Making waste in the first place is the way forward. Let's work together to make a better world.
The film Better Days(少年的你) is bringing attention to school bullying. It's a topic that few
Chinese movies have talked about before. The movie hit theaters on Oct 25,2019. Starring Zhou Dongyu and Yi Yangqianxi, the film earned 450 million yuan in its first three days, China Daily reported.
There are several scenes (场景) of bullying in the movie. For example, in one scene three girls follow Chen after school. They beat her up and tear（ 撕 碎 ） up her textbooks and clothes while taking video of the whole scene.
This scene in the movie might be extreme ( 极端的). But it doesn't mean bullying isn't that serious in our life. Last year, 3,407 students were caught for bullying, according to data provided by the Supreme People's Procuratorate (最高人民检察院) in May.
The movie reminds us that while there may be a long way to go, we must have hope. "As long as you are hopeful, there will be someone helping you," said Derek Tsang, the film's director.
China is trying to stop bullying. The government asks schools to take action to stop bullying and to report any bullying to parents. Schools are also asked to work with the government when dealing with such cases.
