—No, you needn't. You can stay here until 5:30.
Do you like exercising in the sun? How much sunlight do you get every day? How much time do you spend in the1? As we all know，enough sunlight is good for our health. It gives us strong bones (骨骼) and good eyesight. It makes us happy and sleep better. Now scientists find out that it can even make you2.
Scientists did tests on mice. They give mice lots of sunlight. After that，the mice3a special thing named glutamic acid (谷氨酸) in their bodies. Glutamic acid does many things for our body. It can improve some of our abilities such as learning and remembering things.
It is OK to enjoy some sunlight for about an hour every day. But you should be4because it is summer now. The sun is very strong around noon. Keep yourself away from the sun around the noon, or it may5your skin (皮肤). It is best to enjoy sunlight in the morning or before sunset.
Why not go out and enjoy the6with your family or your best friends? I'm sure you can be smarter soon.
My parents used to tell me how important school was for me, but I didn't think so. I paid little attention. But one thing let me1realize what my parents meant.
One day, when I walked past a mobile phone store, I saw it was hiring (雇用) new workers! I went into the shop and asked for the job. The manager looked at me for a few seconds2. “Do you have a high school diploma (文凭)?" He said, "Or do you have any3experience?" I felt so ashamed (羞愧的) and I just turned around and left.
I could not fall asleep that night, and I thought a lot about my4. "I must go to school to5my study because I can't do anything without a good education," I said to myself silently.
Everything looked6when I went back to the store years later: the same people and the same design. However, compared with last time, I felt more7. The manager told me they needed new workers. I showed my diploma to the manager. He looked at it and said: "Great! You are8."
Education helps you have a bright future. Now I am not worried about my future because I'm still9in my spare time.

I had the meanest (最刻薄的) mother in the world. While other kids ate candy for breakfast, I had to have cereal (谷类食物) and eggs. When others had Coke and candy for lunch, I had to eat a sandwich. But at least I wasn't alone. My sister and two brothers had the same mean mother as I did.
My mother knew where we were at all times. She knew who our friends were.
We had to wear clean clothes and take a bath every day. The other kids got to wear the same clothes days.
We had to be in bed by 9:00 pm and up at 8:00 am. We couldn't sleep till noon like our friends. So while they slept, our mother gave us work to do. We had to wash dishes, make beds and learn to cook. I am sure she lay awake at night thinking up mean things to do to us.
Through the years, things didn't improve a bit. We could not lie in bed "sick" like our friends did in order to miss school.
My mother was the meanest mother. Out of four children, a couple of us went on to higher education. None of us have ever done bad things. She forced us to grow up into educated and honest people. I am trying to raise my children like this. I will feel proud when my children call me mean, because, you see, I am so glad I had the meanest mother in the whole world.
Do you know 5G? It is the fifth generation (代) of mobile network technology. These new networks are coming.
China just issued commercial licenses (发放商用牌照) for 5G on June 6, 2019. This means that China's telecom companies will be able to offer 5G networks for mobile phone users.
Each mobile network generation is faster and more powerful than the one before it. 1G let us talk to each other. 2G let us send messages. 3G gave us data (数据) and the Internet. And 4G made all of these things faster. What's special about 5G?
5G has a very short delay between sending and receiving information. Now, 4G takes about 100 to 200 milliseconds (毫秒) to send and receive data. But 5G will get it down to 1 millisecond or less-this is almost real-time.
This big change will not only make our mobile Internet faster，but also deeply change our lives. Read on to find out how.
5G + entertainment (娱乐)
5G networks are about 100 times faster than 4G. This means you can download a movie in seconds using 5G.
Also, virtual reality (VR) games will become more popular with 5G. The short delay of 5G will make the games feel even more real.
5G + transport
5C will also bring us safer self-driving cars. These cars can send signals (信号) to each other. They also talk to traffic lights and road sensors (传感器). 5G will allow cars to react (反应) even faster than human drivers.
5G + smart homes
5G also makes the Internet of things possible. Internet of things is a large network that connects everything to the Internet. Smart homes are part of it.
For example, your toaster can automatically (自动地) start making breakfast after your alarm rings. And if its sensor feels the air becoming dry, a smart sprinkler (洒水器) could water your plants by itself.
COVID-19 (新冠病毒) has stopped people from working for several months. In recent days, many people have returned to work. Here is some advice.
When commuting (通勤)
Avoid taking public transport. If you have to take public transport, you shall wear a face mask (口罩) through the ride and try to avoid touching objects in the vehicles (车辆) with your hands.

In offices
Do it three times a day for 15 minutes to half an hour each time. You can only get infected (感染的) if the virus builds up in large numbers. Fresh air can stop the virus from building up.

A young woman named Jessie got a parrot as a gift. But the parrot had a bad habit：It was always rude.
Jessie tried to change the bird. She spoke to the bird with only polite (word) and played soft music to it.
But the bird didn't change at all. It became even (rude). Jessie angrily caught the bird and put it in the fridge. For a few minutes the parrot kicked and shouted. Then suddenly there was total silence.
Fearing that she might hurt the parrot, Jessie quickly (open) the door of the fridge. The parrot calmly stepped out onto Jessie's arms and said: "I am very sorry about my rude language and actions. I want to do everything (correct) my rude actions."
Jessie was surprised to hear that. As she wanted to ask why it changed so much, the bird spoke very (soft): "May I ask what the turkey (火鸡) did?"
