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.

1. Yuan Longping’s ________ could yield much more than traditional types.
A.hybrid super-riceB.hybrid super-cornC.perennial riceD.perennial corn
2. The results of the great achievements made by Professor Hu Fengyi and his team were published in ________.
A.January, 2022B.November, 2022C.February, 2023D.December, 2023
3. Which is TRUE according to the passage?
A.The perennial rice can be planted every four years.
B.The perennial rice can yield twice a year all over China.
C.The perennial rice can reduce 30% of the work of farmers.
D.The perennial rice can be harmful to the environment.
4. You may read the passage in the ________ section of a newspaper.

5. The passage mainly talks about ________.
A.the “Father of Hybrid Rice” Yuan Longping
B.the professor from Yunnan University

文章大意:本文是说明文。文章讲述了树的一生,树的贡献,树木是自然的宝藏,非常值得保护。由树引申出人的一生和树的一生很相似。

【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!

1. What does the writer want to tell us in paragraph 3?
A.When trees are four years old, they are just like little weak children.
B.At the age of 15, trees grow rapidly and become a real adult.
C.Trees are very useful but they can only live to 25 years at most.
D.Trees are natural treasures and are well worth protecting.
2. What does the underlined word “hollow” probably mean?
A.枯死的B.空心的C.腐烂的D.脆弱的
3. Why should we enjoy every minute of our own life according to the passage?
A.Because just like trees, we change a lot as we grow.
B.Because trees devote all their lifetime to satisfying people and protecting the Earth.
C.Because life is meaningful though there are challenges in different periods of life.
D.Because life is becoming better and better with so many beautiful and useful trees.

【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.

1. If a tornado gets close, what should people do to keep safe?
A.Go to a basement.B.Find a small room.
C.Stay in a bathroom.D.Curl the legs up.
2. What can the sensor in a probe NOT do?
A.Measure wind speed and temperature.B.Take photos and videos.
C.Measure wind temperature and pressure.D.Measure wind speed and direction.
3. Which statement about the scientists is TRUE?
A.They risk their lives studying tornadoes.
B.They can easily put the probe in the right place.
C.They get close to a tornado to admire it.
D.With the help of the measurements, they can prevent the tornado forming.
4. The passage mainly tells us ________.
A.what a tornado is
B.how dangerous a tornado is
C.where a tornado may form and travel
D.how scientists do research work on tornadoes
5. You may find this passage in ________.
A.a novelB.a storybookC.a guidebookD.a science magazine
