Food is the first necessity for people. Over the years, Chinese are working on producing enough food to feed a population of 1.4 billion. The “Father of Hybrid Rice”, Yuan Longping, created the world’s first hybrid super-rice, which is able to yield (出产) 20 to 30 percent more than traditional types.
Following Yuan’s footsteps, more Chinese scientists are doing creative work in this field. A research team leading by Professor Hu Fengyi from Yunnan University has made great achievements in developing a perennial rice (多年生稻). The results were published in Nature (《自然》国际学术期刊) in November, 2022.
The perennial rice is a kind of hybrid rice combined (结合) both common types and wild ones. Traditionally, rice should be planted every year. But this kind of rice only needs to be planted every four years. According to the test data of Hu Fengyi’s team in Xishuangbanna and other places in Yunnan Province, perennial rice can yield twice a year. It produce s almost the same amount of rice as the traditional types with much lower labor costs. That can greatly reduce 70% of the work of farmers. In addition, it cuts the use of chemical fertilizers (化肥) so that it reduces the environmental pollution.
The perennial rice is of great importance to the development of China’s agricultural (农业的) production. It is believed that this new type of rice will be more widely grown in the future.

【推荐1】Trees are one of the oldest “citizens” of our Earth. They keep our air clean, reduce noise pollution, improve water quality and provide food and building materials.
Just like us, trees change a lot as they grow. At 1 to 3 years old, young trees learn how to protect themselves. For example, many trees grow thorns (刺) to warn animals not to go near. Most young trees have large, deep green leaves so that they can catch enough sunlight and change it into their food and energy.
When trees are 4 years old, they begin to grow very rapidly and become strong enough to face challenges later in life. At the age of 15, trees become young adults. They grow more slowly and begin to produce flowers and fruit. It is not until the tree is 20 to 25 years old that it becomes a real adult. The tree reaches its largest size. The adult tree gives us shade, oxygen and natural beauty; it is also a great place for a tree house, or a place for us to read a book, listen to music and so on. If we give the adult tree proper care, it will go on to live healthily for many years.
Gradually, trees begin to grow older and older and even die. At this time, they still have their important place in nature. When a tree becomes hollow or part of it becomes dead, it provides a home for small animals and is a source of food for many other animals.
In many ways, the life of a tree is similar to our own life experience. When we are looking at the life of a tree, we learn about that each period of life brings its own form of joy and challenge. Life is hard but the value of life is how you live it bravely. A man who overcomes himself is a real strong man in life. Don’t give up when you still have something to give. Nothing is really over until the moment you stop trying.
Enjoy every minute of the life of the trees as well as ours!

【推荐3】A tornado(龙卷风)is a kind of strong storm with air which moves in a circle quickly. They can move over 200 miles per hour and cause a lot of damage(损坏). As they move across the land, they can easily pick up cars, trucks, and even houses, and then throw them very far. It is important to find a safe place if a tornado gets close.
A safe place could be a basement(地下室)or the lowest floor. If you are in a home without a basement, try to find a first-floor bathroom or a small room without windows in the middle of your house. You should curl up(蜷缩)into a ball and cover your head and neck with your hands.
But there are some people who actually want to get close to tornadoes. They are scientists who want to learn more about tornadoes. One of the best ways to do this is to get as close as possible to the tornado. They use special tools to measure (测量) what is happening in and around a tornado.
One special tool is called a tornado probe(探测仪). Inside the tornado probe, there are sensors(传感器)to measure wind speed, temperature, pressure, and direction. Some probes even have cameras, so the scientists can see and understand what it’s like to be in a tornado.
To be able to get these measurements, the scientists have to get a tornado probe near or into a tornado. Scientists will try to guess where a tornado will go next. Then they drive to that location and put down the probe. If they do not guess correctly, they pick up their probe and try another place. If they are right, the tornado will go near or even right over the probe. Then they take all of the measurements from the probe and use them to predict where future tornadoes may form(形成)and travel. And they can give people some warning to keep away from a dangerous tornado.

【推荐1】The Yellow River and Confucius (孔子) are two symbols of Chinese culture. Confucius thoughts were born and developed in the Yellow River basin. They both value farming and kindness. When it comes to the Yellow River culture, people have to talk about Confucius. So you decide to introduce Confucius to the world.
Confucius was one of the greatest teachers in ancient China who helped shape Chinese culture. He influenced Chinese education in many ways. But he didn’t usually give lessons by doing most of the talking. His teaching was done more in the form of conversations. In his whole life, about 3000 young people studied under Confucius and they recorded his sayings which were later edited into a book. The book is known as “The Analects” by the world.
Confucius changed his teaching style according to the needs of each student. One day, one of his students, Zi Lu, asked him a question, “When I hear a piece of good news, should I put it into practice at once?” Confucius replied, “You should always first ask someone with more experience.” A few days later, another student named Ran Qiu asked the same question. But Confucius replied, “Yes, put it into practice right away.” A third student heard the two conversations. He asked Confucius why he gave different answers to the two students.
“Ran Qiu always hesitates (犹豫) in making decisions. This is why I encourage him to move forward,” said the teacher. “Zi Lu, however, always makes decisions too quickly. Therefore, I want him to think twice before he does something.” See? ________. And that was how Confucius taught his students.

【推荐3】Many people have pets in the U.S. About 40% of homes have a dog, and 33% have a cat. Many of these people have more than one cat or dog. Other popular pets in the U.S. are birds, fish, hamsters and rabbits.
But people in other countries have different ideas about pets. In Arab countries, for example, dogs usually aren’t popular, because people believe they aren’t clean. And in Africa, very few people have animals as pets.
Some people in China and Japan have small but noisy pets. They aren’t dogs, cats, fish or birds but fighting crickets (蟋蟀). There are even cricket contests in Tianjin every September!
The Eskimos (爱斯基摩人)of northern Canada have dogs as pets. Their dogs also have a job. They pull sleds that help people get around in the snow.
Another example of an unusual pet is the Madagascar hissing cockroach. It’s pretty big but clean, and it sometimes makes a loud noise. Madagascar hissing cockroaches are good pets for kids.
In Australia and Indonesia, some people have marsupials (有袋类动物)such as sugar gliders or kangaroos. These animals have a pocket for their babies. Sugar gliders “fly” from tree to tree.
