新素材 社会热点 People are spending much money buying mystery boxes(盲盒) these days. Usually, there are toys in mystery boxes, but now shops are putting food in them. They are “leftover(剩菜) mystery boxes”.
They are more and more popular in China's cities, such as Beijing, Nanjing and Chengdu. The food inside is near its expiration date(保质期) and will be thrown away if no one buys it.
Each box costs a little money but has a lot of food inside. I buy leftover mystery boxes from an app called Too Good To Go. Each box costs about 3 to 5 pounds(27 to 45 yuan), and there are usually three to four things inside. For example, a box I buy from the coffee shop has three kinds of bread and one cake. The box costs 3 pounds but the original price(原价) is around 10 pounds. Every time I buy a mystery box, I feel happier thinking about how much money I can save. Wasting less food is also good for the environment(环境).
But the boxes also bring me problems. Because I can’t choose what’s in the box, sometimes I get the same kind of food. Also, the food may not be nutritious(有营养的) enough. I have to make other dishes, such as a salad, to make the meal healthier.

新素材 科普知识 About 80% of people do not get enough vitamin(维生素) D every day, but this vitamin is very important for our health.
Vitamin D is really important for our bones(骨骼). When we are young, vitamin D builds up our bones and makes them strong. When we are older, we still need vitamin D to keep our bones strong. Our bodies keep vitamin D in our bones and teeth. Then we lose vitamin D as we work and exercise during the day. Our bodies can’t make vitamin D, so we have to get it from the outside of our bodies.
Where can a person get this very important vitamin? Vitamin D is in food like fish and eggs. Sometimes, vitamin D is added to bread, milk and orange juice. Food is not the only way that our bodies get vitamin D. The sun also gives us vitamin D. If we want to be healthy, we should spend some time in the sun each day. Too much sunlight is not good for us, but about 15 minutes a day is usually enough. We should also be sure to eat food that is rich in vitamin D.
