2 . It’s time to say goodbye to 2020. Life is not easy in 2020 because of COVID-19 (新冠肺炎). Everyone knows it’s important to keep healthy. But how can we do that? Here are some tips (建议).

The first thing is to eat well. Look at what you eat. Is your food healthy? Ice cream, hamburgers and cola are not healthy. Chicken is healthy but too much chicken is bad for you. Eat the right food and you can be healthy. Milk, fish and sweet potatoes are good for your teeth (牙齿). Carrots and eggs are good for your eyes. Please always remember (记住): Have a good breakfast every morning. Eat fruit and vegetables. Drink water, tea and milk, not cola.

The second thing is to play sports. Ball games are great. You can play soccer, basketball or ping-pong with your classmates at school. And you can play them with your family, too. Don’t always sit on the sofa to watch TV or play computer because a couch potato is easy to be fat.

The last thing is to sleep (睡觉) well. Sleep for eight hours every night. Then you may feel good the next day.

To be healthy is not so hard. Do the three things well, and then you can be healthy. I hope you can have a healthy lifestyle.

3 . Children like to eat hamburgers, fries, hotdog, and ice-cream, although parents and teachers tell them not to eat them. It’s not hard to see why they are so popular among them. They’re delicious! But not everything that tastes good is good for you. The next time you need to think about smart food.

Most people love French fries made from potatoes. Did you know that other vegetables taste great, too? They are carrots and sweet potatoes.

There are many healthy things in them, and they can all do the jobs a potato can do. Carrots are fresh and crispy (脆的). Cooked sweet potatoes are full of nice smell. Peel them and cut them into strips (条状), just like fries. Give them a try! You’ll forget all about French fries.

Finding out new foods can be fun. What’s more, if you eat healthy foods, probably you’ll not get sick. You’ll also have a good body to run and play. And you will be able to think more clearly and for longer periods of time. So, start food smartly!

4 . You know that whole thing about drinking eight glasses of water a day? Sorry to have to tell you this, but it may not do you as much good as you think. It won’t make your skin brighter. It won’t make you feel more clearheaded. It won’t make you more energetic. It will, however, make you have to pee a lot. After all, your body can’t take that much water, so it needs a way to get out.

Most of the time, your body will tell you when you need to drink water, because you have these wonderful, amazing, undervalued things—kidneys(肾). Every day, the blood in your body passes through the kidneys. What you eat and drink, the temperature around you, and how much you exercise—all of these do something to your body. Your kidneys，with your nervous system(神经系统) and different kinds of hormones(荷尔蒙), care about what your body needs and keep the balance of your body.

For example,after exercising for a long time, you may sweat a lot, so you’re losing water from your blood. The kidneys know your blood volume(容量) is going down and the blood is getting saltier(含盐量更高). They want more water back into the blood to keep the balance. So they will give you a sign to drink, which means you will get thirsty. If you don’t have enough water, the thirst message will get stronger and stronger.

A lot of people may say that they don’t drink much water, but here’s a point that’s often missed: there is water in every single thing you put in your mouth. Your morning milk has water, so does you breakfast. And that snack—an apple, an orange, or a glass juice, just like you, is made of water too.

5 . A 3-year-old girl normally weighs around 14 kilograms. But 3-year-old Peppa, who borrows her online name from a popular cartoon, weighs 35 kilograms. That is because her parents fed her on hamburgers, rice, roasted meat and sausages almost every day.

And then they posted videos on the Internet showing Peppa gobbling (大口吞吃) all that food for money. Media reports say in one video the girl is clearly seen saying she cannot eat any more, but her parents force her to eat more to create a “big stomach queen” to draw eyeballs and make more money from people watching it. In some of the videos, the girl is seen walking with difficulty, her legs being unable to support her weight.

As the video spread quickly online, users got angry at what Peppa’s parents had done and caused the video platform (平台) to delete Peppa’s videos and no more allow her parents to land on it.

__▲__. Even if Peppa’s parents now stop forcing food down her throat, it will still take a very long time before her weight drops to a healthy level. Besides, being overweight places her under risks of diabetes (糖尿病) and high blood pressure, which can become life-long illnesses.

Peppa’s parents, who made money at the possible cost of Peppa’s pains for life, should be made accountable and pay for their wrongdoings. On the other hand, online video platforms, which encourage such risky videos to make money, should also accept due punishment.
