1 . 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（影响） how children’s brains grow. If children use screens for more than one hour a day, they might have lower levels of white matter in their brains. White matter is a 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 ages 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.

2 . Once there were many thousands of Gourma Desert (沙漠) elephants in Mali, a country in West Africa. Now, there are fewer than four hundred.
Why did the number of the elephants drop so quickly? On the one hand, the elephants’ main lake, their only water source (来源), dried up. On the other hand, the land which the elephants lived on was overused by humans.
To protect the elephants’ living environment, the Mali Elephant Project (MEP) was started in 2007. MEP met with local people and helped them make rules of using land and water. As a result, the situation became better and there was more food, forest and grassland.
However, from 2012 to 2016, poaching (偷猎) and illegal trade in the elephants increased rapidly. Eighty-three elephants were lost in 2015 alone, and another fifty-one elephant were killed in 2016. “If this situation goes on, all the Gourma elephants will be killed by 2020,” said a member of MEP.
Luckily, the voice of MEP was heard. More organizations (组织) have joined together to educate the local people that trading elephants is against the law. Elephant poaching has dropped to a very low level. The local people have learned to live peacefully with the elephants, one of the wildlife treasures in the world.

3 . Bi Sheng was born in Song Dynasty. He lived in a small village which lies in Huanggang today.He invented the printing around 600 AD (公元)。He was the world’s first inventor of the printing. It is about 400 years earlier than the printing in Germany.
The printing is also called the movable type printing (活字印刷).But how did it work in the past?
First of all, the clay was made into movable types. Then words were engraved (雕刻) carefully onto the types. After that the words were chosen and put in right order in a box according to the text. Next, the workers brushed ink onto the movable types. Finally the types could be used for printing. They could be used again and again for different books.
The movable type printing plays an important role in Chinese culture. With the help of it, Chinese culture spread around the world more quickly. At the same time, the movable type printing was widely used in the world at that time. As a result, more and more culture communication among countries took place.
The movable type printing, the compass (指南针)，gun powder and the paper-making are called four great inventions of China. They make China own an important and even top position in the history of human civilization (文明).

4 . “China is always well protected by the bravest of them.”former US secretary of state Henry Kissinger once wrote. Indeed, in the fight against the novel coronavirus, it is medical workers who are risking their lives on the frontlines of the epidemic(疫情).
From February 17, more than 32,000 doctors and nurses from all over China have been sent to Hubei, the center of the epidemic.They are working under unusual conditions, unimaginable stress and intensive(高强度的) schedules.
In hospitals, doctors and nurses work for long hours, usually six hours in a row. Many of them have deep marks on their faces from wearing masks and goggles(护目镜). They also choose to wear diapers(纸尿裤), as it takes nearly an hour to take their protective uniforms on and off. When they are racing time to save lives, every second matters.
To cheer each other up, medical workers wrote inspiring words on their uniforms, such as “Stay Strong” and “Hope”. They strongly believe that they will win the fight against the virus.
These medical workers are just common people. But with their white coats on, they become the bravest fighters.

5 . “This is John,” said Mr Turner. The boy standing next to him was tall, with a friendly face. I noticed Adam and Chen give each other the thumbs (大拇指) up. That meant they were going to invite him to join the cool group. They smiled at him and he smiled back.
Mr Turner always gave new students a buddy with the same hobbies as them. I was sure he wouldn’t choose me. I wasn’t one of the cool kids.
“Hyun, I want you to be John’s buddy this term,” said Mr Turner. Me? I couldn’t believe my ears! Everyone in the class looked in my direction. Adam and Chen even looked unhappy.
John walked over to my desk and sat down beside me. He smiled at me. “Hello,” he said in a confident voice.
“Hello,” I replied, not looking at him.
All morning I could feel the boys in the cool group looking angrily at me, but John didn’t seem to notice.
Finally the bell rang for a break. I had butterflies in my stomach. I knew that Adam and Chen were going to make fun of me in front of John, and that John would decide that he’d rather be buddies with them.
Sure enough, as soon as we got outside, Adam and Chen swaggered (大摇大摆地走) up to us.
“Mr Turner says you’re a good basketball player, John,” said Adam.“How’d you like to play with us at lunch break? Hyun doesn’t know anything about basketball."
“No thanks,” said John.“I’d rather play chess with Hyun, if he doesn’t mind. Mr Turner says he’s an excellent player.”

6 . How did people tell the time before clocks were invented?
At first, the ancient people looked up at the sun and could tell it was the middle of the day when the sun was directly overhead in the sky. They also knew when it was morning or evening.
Later, the Egyptians used sticks. These sticks measured (测量) time during the day. The sun shone on the tall stick and the stick made a shadow (阴影). As the sun moved across the sky, the position (位置) of the shadow changed. This would let people tell what time it was.
Over time, the Chinese first used sundials instead of shadow sticks. The sundial has a type of shadow stick on it. As the sun shines on it, a shadow appears on the numbers. Each number stands for an hour of the day. But sundials don't work at night or on a cloudy day! There are no shadows unless the sun is out.
Water clocks used water to measure time at night. Water dripped (滴落) slowly from one bowl into another. The level of the water in the bowls showed the time.
People also used sand-glasses. You may have seen one. Some games still use sand-glasses. The sand falls from the top of the sand-glasses to the bottom. It measures short amounts of the time. The more sand falls, the more time has passed. When the sand has finished falling, you have to turn the sand-glasses over.

What is Beidou？Beidou is a navigation（导航）satellite system.It is developed by China.China is the third country in the world to have its own navigation satellite system.With Beidou，China no longer has to rely on foreign systems.This is very important for national safety.
The research and development of Beidou began in 1994.However，the first two Beidou satellites were not sent into space until 2000.Since then，China has launched dozens of Beidou satellites.These satellites have formed a global network.Now，China is further improving the system.The BDS—3 system will be fully completed in June，2020，with the launch of the last satellite.
The Beidou Navigation Satellite System will be more powerful than any other navigation satellite system in the world.Yang Changfeng is a designer of Beidou.He said the system can notice the sway（晃动）of a building in strong winds.
Beidou has brought much benefit（益处）to our lives.In many cities，thousands of buses have been using Beidou.When we are waiting for a bus，we can know when it is about to come.Many smartphones have also been using Beidou."Many people say，‘Let me turn on my GPS'.In fact，their phones are using Beidou，”jokes a salesperson in Beijing.
