It might be fun to use your smartphone, but be careful. Too much screen time may be harmful to your health.
First, it is bad for your eyes. A researcher called Sarah Hinkley says the problem comes from the blue light that the screen gives out. Looking at a smartphone for a long time can cause eye strain (劳损), headaches and dry eyes. So it is a good idea to take a break every 15 minutes when you are working at a computer or using a smartphone.
Second, screen use can do harm to children’s brains. A new study shows that using screens too much can affect how children’s brains grow. If children use screens for more than one hour a day, they might have lower levers of white matter in their brains. White matter is the key to the development of language and reading skills. So it is wise to cut down the time of children using all kinds of screens.
Third, using screens too much will affect your sleep. According to a study, about 95% of the people between the age of 13 and 64 use electronics before bed, especially the young people under 20. Doctors say that the light from those electronics at night may make you excited before you go to bed. Then it’s hard for you to get enough sleep. So you’d better turn off smartphones, TVs, and all other screens an hour before your bedtime.
To keep healthy, doctors and researchers strongly advise that you shouldn’t use screens for long hours.

World Smile Day is just the day that people around you would make you laugh. It is celebrated on the first Friday of October every year. This year, it is on October 7. The holiday was set up by an American artist called Harvey Ball. Ball created his famous yellow smiling face symbol in 1963. People loved it and more and more businesses began to use it. Ball became worried that the symbol was losing its original (原始的) meaning. To remind (提醒) people to spread the “real” smile, he had the idea for World Smile Day.
The meaning of the day is, “Do something kind. Help one person smile.” This can be as simple as smiling at everyone you meet. You can also cook a meal for your parents to make them smile. Let’s take these simple steps to make people around you smile!

In some science fiction movies, evil robots refuse to die, no matter how hard people fight back.
Now science fiction has become science fact. For the first time, scientists have made a robot that can take a beating and keep on going. Scientists from Cornell University made the robot, which looks like a spider with four legs.
Until now, even the most advanced (先进的) robot was almost certain to break down when it was damaged (毁坏). That is because its computer inside simply doesn’t know how to make the machine work after its shape has changed.
To deal with this problem, the scientists put eight motors (发动机) and two sensors (传感器) that read how the machine is working. They all give signals to the machine’s software. Using this information, the computer can then figure out the machine’s shape at any moment.
The new technology is a big advance in robot-making, scientists say, and it’s far from scary. It may someday help scientists create better artificial (假的) arms and legs and give new freedom to people who lose them. It might also help scientists understand how people and animals figure out their own sense of place in space.
“It has been difficult to design robots that can work well when the environment changes or when it’s damaged,” says Olaf Sporns of Indiana University in US. “With this work, we are nearer to solving this problem.”
1. Why do robots easily break down when they are damaged?
A.They cannot repair themselves. |
B.The computer has changed a lot. |
C.They have no computers inside. |
D.The computer cannot work if the robot changes. |
A.keep working after being damaged |
B.tell people where it is |
C.do house work for humans |
D.remember a lot of information |
A.sensors | B.robots | C.scientists | D.arms and legs |
A.They can replace the computer when it’s broken. |
B.They help the computer learn the robot’s condition. |
C.They can find out where the damage comes from. |
D.They can send signals to the person who uses the robot. |
【推荐1】For the second part of the exchange visit, I went to London with my classmates. I was very happy to meet Sarah and Eric and other students. Going to a Woodpark school was an educational and exciting experience for me.
On the first day, we attended a school meeting. I sat next to a girl named Diana. We soon became best friends. At the meeting, the headmaster told us about the rules of the school. He also told us that the best way to earn respect was to study hard and get high grades.
I had many teachers during the month. Mr. Heywood, my class teacher was very helpful. In our class there were 28 students. We had to move to different classrooms for different classes.
The homework was not as heavy as what I used to get in my old school. However, it was a bit challenging for me, but all my teachers encouraged me and I did well in all my subjects including cooking.
My English improved a lot and I learnt a lot about British culture and history. I practiced using English every day and spent an hour each day reading English books in the library. I usually went to the Computer Club during the lunch break, so I could send e-mails to my family and friends back home for free. Cooking was really fun. At the end of the visit, we had a class party and we had to cook something. I was glad that all my classmates were fond of the dumplings that I made.
I was very lucky to experience this different way of life. And I really hope to go back to study in England one day.

【推荐1】How many of us could go a week without(不用)our phones? I can’t even remember the last time I went a day without the Internet. Technology(科技)makes our life easier. However, we have to face the fact: Technology makes us lazy.
In the past, when we wanted to do something relaxing, we got dressed and drove to the movies or went out to have fun with friends. Now we don’t need to go out. ▲ We just sit on the sofa and turn on the computer. Then we can have much fun.
We find the answer to anything with Baidu. When we have a problem, we usually try to find out the answer online. Many of us don’t try to read books or ask for help to work out the problem.
I get the feeling that we’re getting closer and closer to the day when people won’t even be able to read paper maps. Many young people have no idea how to find a place in their own cities without using a BDS.
How can we detach from too much technology? Using technology becomes one of our habits and we can never stop using it. What we can do is to start doing things more without technology.
We have to learn how to enjoy our free time without it. Although it’s not easy, we can start from small things. For example, turn off phones and computers from time to time and check(检查)e-mails and QQ or We-chat only once or twice a day. We can also do something interesting without using technology, like playing sports and walking a dog.

【推荐2】On Oct. 25 this year, the Healthy China Action (2019-2030): Tobacco Control Promotion Campaign(控烟行动) came out in Beijing. It shows about 9.4 million junior high school students tried tobaccos(烟)before.
How did this happen? First of all, stopping smoking in public(公共) places is difficult. It’s easy for teenagers to buy tobaccos on streets. And it’s hard to find out who is smoking in a place full of people. And how to punish(惩处) them is a question. It will use much money to make people ask others not to smoke in public places. So, some units(部门) just have to let it go.
There’s another reason we should know. Although we can’t find tobacco ads(广告) on TV or newspapers, there are many other ways for teenagers to see tobaccos. Today we can see actors and actresses smoking in the movies and soap operas. Also, pictures of singers and actors smoking are everywhere on the Internet. As a result, 13% of the students in the schools of Beijing think smoking makes them look cooler. “Did you see Chow Yun Fat in the movie God of Gamblers(赌神)? Smoking makes him so manly and cool! If I can smoke, I’ll look fantastic, too.” said a 13-year-old boy student.
How can we make things better? First of all, stars shouldn’t smoke in their programs too often. And news about stars and singers smoking should also become less. The less teenagers see their favorite stars smoke, the less they want to smoke themselves. Schools and families must take actions, too. Teachers and parents mustn’t smoke in front of the students or kids. And we should let teenagers know the bad things about tobaccos. We can also have people share ideas about tobacco control in schools, so students can join the action.
