1 . Ant Forest has been given the UN’s highest environment award—Champions of the Earth. The award was set up in 2005 to recognize (表彰) excellent people or organizations that have had a good influence on the environment.
Ant Forest encourages people to have greener lifestyles to protect the environment better. You are encouraged to record your low-carbon footprint through daily lives like taking the public transport or paying for electricity, heat and water online. For each action, you receive “green energy” points. When you reach a certain number of points, a real tree will be planted. And you can see pictures of your trees in real time by satellite.
Ant Forest has turned people’s green good actions into real trees. Since its beginning in 2016, Ant Forest has planted around 122 million trees. The trees cover an area of 112, 000 hectares in some of China’s driest areas and have prevented more than 7 million tons of carbon emissions (碳排放) from entering the atmosphere (大气层).
“Ant Forest shows how technology can change our world,” says Inger Andersen, Executive Director of the United Nations Environment Program. “Although the environment problems we face are discouraging (令人沮丧的), we have the technology and the knowledge to overcome them. The green activities will help create a better world.”

2 . As Chinese traditions go, few things are better than sitting around a hotpot while autumn and winter come over North China. Studies show that Kublai Khan, the emperor of the Yuan Dynasty (1271-1368), invented mutton hotpot.
For a long time, only Beijing’s rich people could get their hands on mutton hotpot. Emperor Qianlong (1711-1799) was a true hotpot lover, eating the dish more than 200 times in 1789.
Among the vegetables and meat spread out on the dinner table, mutton has been placed front and center. Many people believe mutton has the effect (效果) of warming the body, making it an ideal food for the colder months. Sheep are also generally fattened up after a summer of eating, making them perfect for meat lovers through the winter.
The Chinese capital is home to more than 2,000 mutton hotpot restaurants, according to the food platform Dazhong Dianping. There are well-known hotpot brands such as Jubaoyuan, Manfulou, Yangdaye, Nanmen and Donglaishun.
Today, many mutton hotpot restaurants divide the meat into many kinds according to which part of a sheep it is cut from. An experienced cook can cut the meat so thin that people can read the words of a book through the piece of the meat.
In the old days, restaurants in the capital only started serving mutton hotpot from Mid-Autumn Festival (the 15th day of the eighth lunar month). Business often stopped after Spring Festival. Restaurant workers would have to find a new job after Dragon Boat Festival (the fifth day of the fifth lunar month), when business came to an end. Nowadays, however, people can enjoy the mutton hotpot all year round with technological development in mutton production across the country.

3 . DNA is the whole “map” of the human body. It is something that all humans have, and it tells the body what to do. DNA is the reason that we look like our parents, because we get some of their DNA to make our own.
People have been trying to understand the human body for a long time. In 1860, Mr. Mendel discovered why we look similar to other people in our family. It is because of small things called “genes” in our body. In 1953, two scientists, Watson and Crick, found out that those small parts are real messages. They are written in the DNA with a special language.
In 1961, another two scientists found the first “word” that they could understand in that language. It shows how DNA tells the cell （细胞） to build its parts. So far, scientists have found all the words in the DNA map, but we do not understand what they all do. By understanding what just one “word” means, we can help to save people from several illnesses. So the more we understand, the more doctors will be able to do.
Most people hope that this will help to make better medicine to help sick people. Other people worry that when we learn more “words” and find out more information, we will use it in the wrong way, just to make people more attractive, or stop sick people getting jobs.

4 . Nexi is one of a new generation of robots. It moves on wheels and can pick up objects. But robots like Nexi are more than just entertaining toys.
Nexi, a social robot created by scientists at the Massachusetts Institute of Technology(MIT), can express human emotions. Roboticists at MIT call Nexi a “social robot”. A social robot is a robot that can communicate like a human. Nexi can look sad, mad, and even bored. Some social robots can also “read” our facial expressions. Roboticists believe that it won’t be long before we have social robots in our homes, helping us live better lives.
Autom is another social robot developed at MIT. Autom is a robot health coach. It has a screen where you enter information about what food you eat that day or how much you exercised. Autom has a face with eyes that move. It speaks with a synthesized（合成的）voice. Autom gives you advice about your diet and exercise and drives you to do better.
In a test, Autom helped people lose weight better than other ways of recording diet information. Roboticists think this is because Autom used facial expressions and words of encouragement. In other words, Autom communicated like a real person. In fact, many people who used Autom gave the robot a new name and talked to it. When robots use human expressions and body languages, people reply to them a lot like they reply to people.
In the future, humans may communicate with social robots just like they do with other people. Let’s wait and see what will happen in the future!

One day, you open the fridge and find some moldy (发霉的) food. But before you can throw it away, your mother stops you. She doesn't want to waste food. She cuts off the moldy part and eats the rest. Is it safe to do this?
Mold (霉菌) can grow on almost all kinds of food. Mold is usually green, white, black or gray. Mold makes food soft and changes its color. Moldy food tastes quite bad—and it's not safe to eat.
If you find mold in soft food, just throw it away. Bread, tomatoes and hot dogs are soft food. This kind of food allows mold to easily grow below its surface.
But it's easy to remove mold from hard food. The mold can't grow very deeply inside this kind of food. According to the BBC, you should cut about 2.5 cm around and below the mold and remove it.
It's OK to cut the moldy parts out of hard food and eat the rest. But if the food is completely covered with mold, you should still throw it away.
Most kinds of mold are bad for us. But some kinds of mold can be used to make food. For example, peniciliium (青霉菌) can be used to make many types of cheeses, such as blue cheese. These cheeses are safe to eat and they're quite delicious as well.
