When you do your homework, you may often meet some problems. How do you solve them? Linda, a middle school student, would take out her smartphone, open a special app(应用)and search the problem. Answers soon appear on the screen.
Nowadays, many students do homework with the help of the special apps like Linda. “It’s convenient. You don’ t have to go out or wait for a tutor(家庭教师) at home.” Linda said. “You also learn by seeing how others work them out. It’s very helpful and improves students’ abilities” said John, another student. He said it was especially true for new types of homework.
John’s Chinese teacher often asks students to give speeches on great writers. When it comes to John’s turn, he usually searches online, picks out certain stories and makes PPTs. “I’ve become skilled at finding information online and using Microsoft Office,” John said.
However, many people think this trend (趋势)also brings up problems. Some students just copy the answers online without thinking. They become lazy.
Head teacher Mr. Wang in Linda and John’s school thinks that knowing how to use the Internet is important. The key is to have good self-control. “No matter how difficult the problem is, think about it by yourself first. Remember not to depend on the Internet too much.” the teacher said. “Be sure to understand the reasons behind the answers, or you won’t make progress. If you don’t have confidence in your self-control, ask your parents for help.”

If you look at the top of your phone ,you'll usually see a little symbol that says 3G or 4G. The "G" stands for the "generation" of your mobile network.But these symbols will become things of the past after 5G fully arrives.
On March 30th, 2019, Shanghai vice-mayor Wu Qing made the first 5G video call on a Huawei Mate X smartphone, CGTN reported.Shanghai has also become the first city in China to start testing 5G networks.Monaco became the first country in Europe to use a next-generation 5G mobile phone network based on technology from Chinese company Huawei.
It sounds obvious, but it’s important to understand just how much faster 5G is compared to current 4G speeds. 5G will not only be many, many times faster than your existing connection, it will be greatly faster than the broadband connection you have at home.
Now, 4G takes about 100 to 200 milliseconds* to send and receive data.But 5G will get it down to 1 millisecond or less.This big change will not only make our mobile Internet faster. It can be used in many other ways as well.
For example,5G will help to make self-driving cars safer.Today's self ﹣ driving test cars have one problem ﹣ lag.When the car"sees"an obstacle*, it sends this information to a data center and receives instructions. However, it takes time to send and receive this information. With this kind of lag, the cars might crash because they don't receive instructions in time. With 5G, this lag will be greatly lowered, making the cars safer,according to CNN.
5G could also be used to power the Internet of Things (IOT). This refers to a large online network that connects all things and people.Fast Internet speeds will be the key to developing this technology. For example, with IOT under 5G, your fridge could automatically* place an order online for eggs when it finds that there are no eggs left inside.
All in all, 5G will shape every type of technology that it touches. And you won't have to wait too long for that to happen. Though we’ve seen a lot of positive progress just in the last year, we still have a long way to go before 5G is anywhere near as common as 4G is right now.

Meet Sortee is a puzzle game developed by Flow Studio, a UK company. It makes you think deeply about everyday objects and their meanings.
The rule of the game is quite simple. Two bins are placed on either side of the screen. Each of the bins has a label (标签) next to it and the label explains what it is for. When an object, such as a car or an apple, appears on the screen, you need to decide which bin it should be sorted into and then send it there by moving your finger.
The game seems easy enough at first. But as you move on to more levels, it gets harder. The number of bins increases to three or four and the time given gets shorter. You need to think and move faster. That can be really difficult.
There are 400 0bjects in total and more than 100 bins in the game. The more objects you correctly sort, the more game coins you can get It's a bit like working in a rubbish recycling center, but it has no bad smell.
You can download the free game from Apple's app store (苹果软件下载中心), but it only lets you play the first few levels. If you want to open the next 40 levels, you need to pay 6 yuan for the full game.
