You might have noticed that sometimes, when you are playing mobile games, the picture suddenly freezes(卡顿)because the network speed is o slow. However, these annoying things will soon become a thing of the past, as China just issued commercial licenses (发放商用牌照）for 5G networks on June 6, 2019. This means that China's telecommunications companies will be able to offer 5G network speeds to users.
The "G" in "5G"stands for generation. IG let us talk to each other, 2G let us send messages, 3G gave us mobile data and internet, and 4G made all of these things faster. So what will SG bring?
It will allow us to download an entire HD movie in seconds. The delay(延时)between sending and receiving data will be shortened. Now, 4Gtakes about 100 to 200 milliseconds, while humans have a reaction time of about 200 to 300 milliseconds. But 5G will get the delay down to I millisecond or less, which is almost real—time.
With the development of 5G, new kinds of technology will be created and used.
Robots will be used to do operations because doctors will be able to control them from somewhere else without any delay. Self—driving cars will be able to drive more safely because they can smoothly communicate with each other, traffic lights and road sensors.
5G networks will be powerful, but not perfect. They do have some disadvantages.
On one hand, 5G signals don't go very far. On 4G networks, you can be 10 kilometers away from the nearest transmission base(传送基站）and don't lose signal. But 5G maxes out at about 300 meters. On the other hand, 5G signals have a hard time going through walls and rains. This means we will need to build many small transmitters to make sure 5G signals can be received everywhere. Soon you may see small boxes on every street lamp and building.
1.Why does the picture freeze when we are playing mobile games?
2.What does "G" in"5G"stand for?
3.How long will it take to download an entire HD movie with 5G?
4.What is the fourth paragraph mainly about?
5.What disadvantages do 5G networks have?
If you know a teenager or gamer, you have probably heard about the latest video game: Fortnite. In the game, up to 100 players land into a small island with guns, and then kill or hide from other players in an attempt to be the lone survivor. The main goal is to kill other players. The popularity of these types of games raises clear questions about the effects of violent(暴力的)gaming. Do violent video games lead to real life violence?
The research on this question is mixed. Over the years, researchers have performed studies to find out whether violent video games lead to problems such as aggression(攻击性）and poor performance in school. Many studies have found that people who play violent video games are more likely to be involved in aggressive behavior. In fact, there was enough research leading to this conclusion(结论）that the American Psychological Association published a policy statement in 2015 concluding that playing violent video games leads to more aggressive behaviors.
But many other researchers disagree. Many studies about violent crime and the use of video violent games find no evidence that increased sales of violent video games leads to an obvious growth in violent crimes. Researchers state that if violent games directly led to violent behavior, the data(数据)would show increases in violent crime on a large—scale as more people played violent games. In fact, there is some evidence that as more youth play video games, rates of youth violence have decreased.
A recent analysis finds that much of the research on violence and video games is affected by publication bias. Studies which drew the conclusions that video games lead to aggression and violence are more likely to be published. However, studies which find violent video games don't have an effect on violence are seldom to be published. As a result, large reviews of the data conclude violent video games lead to aggression without considering research to the contrary.
So what's the take—home message here? There is not enough evidence that violent video games lead to aggressive behavior. That does not mean that every game is for every child. Certainly, many violent video games are scary and unfit for some kids. Understanding each child's needs and creating a plan that sets out rules for media use and monitors kids' activities on screens are proper solutions.

When thinking of ways to relax in life, usually things like yoga, jogging and music come to mind. These are great, to be sure. But getting a friend can also have many benefits. While human friends provide great social support, furry friends like cats and dogs can come with some great benefits.
Pets can improve people's mood. For those who love animals, it's actually impossible to stay in a bad mood when a pair of loving puppy eyes meets yours, or when a super-soft cat rubs up against your hand. The study found that people with AIDS were less likely to suffer from deep sadness if they owned a pet.
Pets also encourage people to get out and exercise. Whether people walk their dogs because they need it, or are more likely to enjoy a walk when they have companionship, dog owners do spend more time walking than non-pet owners.
While we all know the power of talking about your problems with a good friend who is a good listener, research shows that spending time with pets may be even better! People actually experience less stress(压力) when their pets are with them than when a supportive friend is present! A recent study performed by Washington State University(WSU) has proved that petting cats and dogs for just ten minutes is an effective way to reduce stress levels. The team chose 249 students and put them into four groups. The first group was provided 10 minutes to play with dogs and cats.
The second group waited in line while observing the first group. The third group watched a video of the same animals, while the fourth group was just waiting. "What we wanted to learn was whether this exposure(接触) would help students reduce their stress, and it did, "said Patricia Pendry, a professor in WSU.
It's important to realize that owning a pet isn't for everyone. It does come with additional work and responsibility, which can bring its own stress. However, for most people, the advantages of having a pet outweigh the drawbacks(缺点). Having a furry best friend can reduce stress in your life and bring you support when times get tough.
