It is easy for many people to catch a cold in the springtime or fall. It makes us wonder if scientists can send a man to the moon, why can't they find a cure for the common cold? The answer is easy. There are actually different cold viruses out there. You never know which one you will get, so there isn't a cure for each one.

When a virus attacks your body, your body works hard to get rid of it Blood rushes to your nose and causes a block in it. You feel terrible because you can't breathe well, but your body is actually eating the virus. Your temperature goes up and you get a fever, but the heat of your body is killing the virus. You also have a runny nose to stop the virus from getting into your cells. You may feel very uncomfortable, but actually your wonderful body is doing everything it can to kill the cold.

Different people do different things to deal with colds. In the United States and some other countries, for example, people might have chicken soup to help them get over the cold. Some people take hot baths. Other people take medicine to stop different symptoms(症状)of colds.

There is one interesting thing to note一some scientists say taking medicine when you have a cold is actually bad for you. The virus stays in you longer because your body doesn't have a way to fight it and kill it Bodies can do an amazing job on their own. There is a joke, however, on taking medicine when you have a cold. It goes like this:

It takes about one week to get over a cold if you don't take medicine, but it takes only seven days to get over a cold if you take medicine.

Eating lots of vegetables is good for our health. Different vegetables can help our bodies in different ways. Eating carrots is good for our eyes. Carrots can help us see better at night. Do you want to have strong teeth? If so, you can eat some peas(豌豆). Peas have vitamin(维生素) K in them. Vitamin K is helpful to your teeth. Do you like tomatoes? They look nice. Doctors call tomatoes "healthy vegetables", because they can help you not to get cancer(癌症). They also have a kind of special vitamin PP. It can keep our skin(皮肤) healthy. So it is important to eat some tomatoes. Don't forget about spinach(菠菜). The spinach leaves have vitamin A, vitamin C and vitamin E. They help our bodies make red blood cells (血红蛋白).Vegetables are very important to us, but we can't only eat vegetables. We also need to eat other kinds of food to keep healthy.

I am David. My home town, Bao Loc, is just a small town in Vietnam (越南). But for me, it's really a paradise (天堂). 

The weather is very comfortable. It's not very hot or cold. In the centre of the town, there is a beautiful lake. You can lie on the bank (河岸) and see the white clouds in the blue sky or count (数) the stars at night. You can go there just to relax when you have a lot of things to think about. One of the most famous places is Dambri Waterfall (瀑布). You can enjoy this beautiful waterfall if you come. Don't forget to take some pictures with your camera. 

Bao Loc is very small. It will take you 45 minutes or 1 hour to go around this town. It's so small that people here know each other. They are very friendly. 

Tea and coffee are Bao Loc's local food. I think you will like them very much. 

Why does Bao Loc become a paradise? Because my family are here and they always make me feel warm and safe.

The 24-year-old volunteer, who is known online as Danni recorded(记录) happy times with her students on her phone. Each of the videos attracts thousands of Chinese netizens who are interested in her volunteer experiences.

After finishing university in 2020, Danni chose to work in Africa for a year and then traveled to seven countries. Finally, she stopped in Uganda because of a primary school. She taught children from Grade One to Grade Four. Danni set up different kinds of classes for her students, such as Chinese language learning and cooking.

Sometimes Danni would cook traditional Chinese food for her students, and she also taught them to speak Putonghua. "Their smiling faces gave me energy(能量) and I enjoyed staying with them," she said.

In 2022, Danni arrived in Lebanon and became a voluntary teacher at a local school. This time she taught arts and crafts(手工艺). At the school, Danni built beautiful friendships with the children. They would run to give her hugs(拥抱) or small presents every morning, and would invite her to their homes.

She had some interesting activities in her teaching such as paper cutting and the making of paper ice cream. Some of her students were good at these and could finish the handicraft works quickly, while some needed a bit of help. The good thing was that they all worked hard.
