Do you know the two lovely mascots (吉祥物)? You may know the five “Fuwa” dolls from the 2008 Beijing Olympic Games. On September 17, 2019, the two lovely mascots first showed on TV. Now, let’s see who they are.

Look at the panda! It looks like an astronaut. It wears an ice shell and looks fat, so we call it “Bing Dwen Dwen”. White is the colour of ice and snow. “Bing Dwen Dwen” likes ice sports very much and is good at them. That’s why it is the mascot of 2022 Beijing Winter Olympic Games. The red heart shape in its left hand means welcoming the friends from other countries. The bright colours of the circles around its face stand for ice and snow sport tracks, meaning connectivity and advanced technologies.

Do you think the red mascot looks like a lantern (灯笼)? The lantern’s name is “Shuey Rhon Rhon”. When the Chinese New Year comes, people always make or buy red lanterns. Red is the colour of hope and good luck, so people think their dreams will come true in the new year. “Shuey Rhon Rhon” can give players hope and help them do well in the 2022 Beijing Winter Paralympic Games (残奥会).

Many people in different countries like the two mascots very much, and they show their love for them on the Internet.

Tom has a happy family. There are some rules in his family.

Keep healthy

Being healthy is important. Tom’s family play sports for one hour every day. Tom is in the school swimming club. And his parents run every morning.

Evening time is family time

They can’t watch TV or play computer games after dinner. The family usually sit(坐) on the sofa and talk. Tom always talks about his school and friends. Sometimes they take a walk together.

Always say “I love you” and “Thank you”

Tom says “I love you” to his parents in the morning before he goes to school, and in the evening before he goes to bed. His parents say it to him, too. When Tom helps his mother, she says “Thank you”. They show their love and thanks all the time.

6 . China is a nation of etiquette (礼仪). Chinese people are among the most hospitable (好客的) people in the world. If foreigners visit a Chinese family, they would be surprised at the warmth that they would receive as guests.

When you visit a Chinese family, the host usually makes tea for you. Then he will serve you snacks like biscuits or candy. Someone in the family will also chat with you, never letting you feel lonely.

At the same time, other family members will prepare a meal for you. Chinese people treat their guests with a big meal. They always present more food than the guest can eat. On the table, the guest must be the first to eat. Perhaps one of the things that surprises a western guest most is that the Chinese host likes to pick food for visitors, which won’t happen at western tables. The Chinese family go out of their way to make you feel at home. As you are done eating, the host usually says, “It seems that you didn’t eat much. Please have more.” Although you tell them you are full, they still put more food in your bowl.

Being warm and hospitable has long been an important part of Chinese culture and tradition. As Confucius (孔子) said thousands of years ago: “To meet friends from afar, How happy we are!”

7 . If you look at the top of your phone, you will usually see a little symbol that says 3G or 4G. The G means “generation” of your mobile network. But these symbols will become things of the past after 5G networks fully arrive.

On March 30,2019, Shanghai vice-mayor (副市长) Wu Qing made the first 5g video call on the Huawei Mate X Smartphone. Shanghai has also become the first city in our country to start testing 5G networks.

More and more people started to learn about 5G because it has many advantages.

5G will let people download and upload the data (上传数据) faster than before.

People can use it for many other things as well. For example, 5G will help to make self-driving cars safer. Today’s self-driving test cars take time to send the information and the receiving instructions. They can’t react (反应) in time. With the help of 5G, this can be greatly improved.

People could also use 5G to power the Internet of Things (IOT物联网). It’s a large online network that connects all things and people. Fast Internet speed will be the key to developing this technology.

5G is on the way. It will lead us to a new world. Are you ready?

8 . Many of us don’t pay much attention to the importance of eye care. It is said that if you take care of your body, then you can surely be healthy. That is why our eyes should be given a lot of care. Natural eye care should be put in a number one place.

There are several causes leading to poor eyesight like not enough food, genes (基因) and aging (老化). Televisions, computers and reading are also the causes of having poor eyesight. If you work in front of the computer, it is best to take a break every once in a while. Something dirty can cause redness and they will make you feel uncomfortable. It is bad for your eyes, too. If this happens, the best way is to clean your eyes by using cold water. You must also try your best to protect your eyes from harmful things. For example, sunglasses are not just for fashion but they can also serve as a great way to protect your eyesight from ultraviolet rays.

Eating healthy foods will do good to your eyesight. Remember that vitamins A, C and E are good for eyes. Try to eat food groups that have these vitamins. And you should do eye exercises because exercise protects your eyesight, too. If a person exercises regularly (定期地) and eats the right kind of food, his eyes will stay in good condition for a long time.

All above are natural ways of eye care that help us keep healthy eyes. Being happy all the time can be helpful to a person’s eyesight, too. In a word, eye care is very important, no matter how old a person is.

9 . The Sydney Opera House is a very famous building in the world. It has become Sydney’s best-known landmark and international symbol. The Opera House with a “sailing roof” was designed by a famous Danish architect(丹麦建筑师), Utzon. The base for the building was started in 1959, years before the designs were finished. Utzon spent four years designing the Opera House. In 1962, the designs were finalized(定稿) and the construction（施工）began. In 1967, they started the decoration inside. It took 14 years in total to build the Opera House. Queen Elizabeth II officially opened it on October 20^th, 1973.

The Sydney Opera House cost around $ 100 million and was paid for by the public. 6,225 square meters of glass was used to build it. The Opera House includes 1,000 rooms. It is 185 meters long and 120 meters wide. The building’s roof sections weigh about 15 tons. Each year, this fantastic building attracts 200,000 tourists to come for a visit or enjoy events in it.

The Opera House reaches out into the harbour(港湾). It is amazing and unforgettable, offering people a strong sense of beauty.

You must think a computer is the best thing in the world, right? You must think it works at a super speed and can do everything? Well, it’s not! In fact, the brain is much more powerful than any super computer! Think about when a glass is just about to fall off the table. Your brain controls everything that you need to do to save that glass from falling. First, your eyes check out what’s going on, then tell your brain, and your brain decides how quickly you need to react(反应), and then your muscles(肌肉) go into action. That is just from your brain. No computers could ever come close to that!

The brain weighs just 3 pounds, but it controls everything you do from thinking, learning, feeling even to breathing and your heart beating. Even though the brain is just 2% of your body weight, it uses around 20% of all your energy in your body. That is a lot for such a small organ(器官). There are about 100 billion tiny, tiny little cells(细胞) in your brain. There are so many that it would take you over 3,000 years to count them all!

Your brain stops growing when you’re 18, but it actually keeps on developing and learning new things. So your parents are really super smart! You won’t be able to fool them! Believe it or not, your brain NEVER stops working. Even during sleeping, the brain works for long-term memory establishment(建立). It is realized that the brain is the second organ in the body as the heart that never stops during human lives.

So everyone should be proud of such a gift of nature.
