3 . Hip-hop dancing (嘻哈舞) is popular with many young people today. They like it because they can invent (发明) their own moves (动作). They use this dance to show their love for life. It also shows that they just want to be themselves and enjoy life, and that they are not afraid of problems.
Hip-hop dancing has a history of more than 30 years. It first began in the 1980s in the United States. At the beginning, people saw it in New York and Los Angles. At that time, lots of young black people often danced to music in the streets. They used their legs, arms, heads and even shoulders to dance. Many dancers still use most of these moves today.
Hip-hop dancing became popular all over the world because of the 1983 movie Flashdance. Actors and actresses performed Hip-hop dancing in the movie. People enjoyed their show. They began to dance like them. Then it became popular.
Now more and more young people in China are learning Hip-hop dancing. They believe that it is a good way to exercise their bodies, and it is good for keeping fit and healthy.

4 . Most people buy a lot of gifts just before Christmas. But some people think we buy too much. They start a special day called Buy Nothing Day. They don’t want anyone to go shopping that day.
Buy Nothing Day is November 29. It’s 25 days before Christmas. It’s after Thanksgiving and often the first day of Christmas shopping. At this time, we see ads in newspapers and on TV telling us to “buy, buy, buy!”
The idea for Buy Nothing Day started in British Columbia(哥伦比亚). Now people all over the world celebrate Buy Nothing Day. In California(加利福尼亚), parents and children get together to read stories, sing songs, and paint pictures. The children talk about why they don’t need a lot of toys. This year, in England, people dress up to tell people that we buy too much.
In New Mexico(新墨西哥州), high school students want to tell other students about Buy Nothing Day. They organize a spaghetti(意大利细面) dinner to give people information about Buy Nothing Day. They ask restaurants in the neighborhood to donate the food. They make posters and talk to other students about it. The dinner is a big success, and many students agree not to buy anything on November 29. The students at high school like the idea of this new tradition. Next year, they want to have another dinner to tell more people about Buy Nothing Day!

5 . The city of music
Vienna is a beautiful old city on the River Danube in the center of Europe. It’s the capital city of Austria and the center of European classical music. In the eighteenth century a lot of musicians came to study and work in Vienna.
In the Strauss family, there were two composers called Johann Strauss: the father and the son. The father, Johann Strauss the elder, wrote and played music for traditional dances, called the waltz. His dance music made him famous all over Europe. The son, Johann Strauss the younger, was also very successful and popular. He wrote over 150 waltzes. In 1867 he wrote The Blue Danube waltz.
Mozart was another very important composer. He was born in Austria in 1756. Before he was six, he played not only the piano but also the violin. His family took him around Europe and he gave concerts in many cities. He wrote hundreds of pieces of music. But he became very poor and died in 1791 when he was only thirty-five. Like Johann Strauss, father and son he was a great European musician, and many people still think his music is perfect.

Scientists understand why summer leaves are green and why they change to yellow or orange in the autumn. But autumn reds are different. Some leaves turn red. Others don’t. It’s amystery. Scientists want to find the answers.
All summer long, a green chemical called chlorophyll catches energy from sunlight for photosynthesis, a process that makes food for the plant. Yellow and orange chemicals called carotenoids are there through the summer, hidden by the chlorophyll. In the autumn, photosynthesis stops, and chlorophyll breaks down.Then carotenoids show through in the leaves. This explains the autumn colours of yellow and orange, but not the reds of trees. The source of the reds is anthocyanin which the leaf doesn’t start making until autumn.
But why do trees use a lot of energy to make anthocyanins in the leaves as the trees are preparing to drop them for the winter?Perhaps anthocyanins help a leaf save nutrients it stored up in the growing season. Dr.Eppes and her students ran a study to test that idea. In a protected area in North Carolina, they counted the types of trees that live in rich soil low on the hillsides, and the types that live in poor hilltop soils. Low on the hillsides, they found more birches and other trees that can’t make anthocyanins. These trees have yellow or brown autumn leaves. On the hilltops, most of the trees were red maples and others that can make anthocyanins, giving them red leaves in the autumn.
“Trees that don’t make anthocvanins seem to naturally live at places where nutrients get added to the soil every time the river floods, ” Dr.Eppes says. “Trees that make anthocyanins seem to live in places without this special ‘meal’.” She guesses the anthocyanins may lie in the soil after he leaves drop, fertilizing the tree in the spring,
Other scientists find that for trees that make anthocyanins, the leaves that get more sun tend to turn redder than those in shade. They think the anthocyanins work like sunscreen, protecting the leaf when it moves nutrients into the tree and stores them for the winter.
Scientists are not sure about why nature paints some autumn leaves red yet, but they are a few steps closer!

7 . The James Webb Space Telescope was launched on December 25, 2021. It’s a space telescope developed by NASA, the European Space Agency and the Canadian Agency. Named after James E.Webb, who created Apollo program, this telescope is a replacement for the Hubble Space Telescope, which headed to space in 1990.
Webb is different from Hubble in some ways. It can see infrared light which makes it possible to look through clouds of gas and dust in the universe and explore the very distant galaxies.With a 6.5-meter-wide golden mirror, it can collect more than six times as much light as the Hubble mirror, so it can see tiny objects more clearly. To “see” faint galaxies in infrared light, Webb needs to be extremely cold, or it would only see its own infrared light. Made of a thin plastic, the heat shield is five layers thick, and it keeps the mirror at minus 234°C. Besides, Hubble moves only about 550 km above Earth while Webb orbits the sun, 1.5 million kilometres away from Earth. This lets Webb stay in line with Earth, allowing the moon to protect it from the light and heat of the sun and Earth.
As the most powerful telescope ever made, Webb is a giant step forward in human space exploration. With it, scientists can observe the very distant galaxies to see how the first galaxies forming out of the darkness. By comparing the earliest galaxies with today’s, they may understand how galaxies have changed over time. It’s also possible for them to study the atmospheres of the faraway planets and search for possible signs of life. Above all, seeing through and into clouds of dust also allows them to find out where stars and planetary systems are being born. This is the primary goal of Webb.
Webb is scheduled to work in space for between five and ten years, so it has enough time to send back fascinating data and images and give us a big surprise.

8 . Having a learning disability (缺陷、障碍) doesn’t mean you can’t learn, but you’ll need some help and you’ll need to work very hard. If you have a learning disability, remember that you are not slow.
Learning disabilities can be genetic. That means they can be passed down in families through your parents, even your grandparents.
“Dyslexia” is a learning disability that means a kid has a lot of trouble reading and writing. Kids who have trouble with math may have “dyscalculia”. Other kids may have “language disorders”, which means they have problems understanding language and understanding what they read.
How do we tell if a student has a learning disability? Reading, doing math, and writing letters may be difficult for lots of kids at first. But when those early troubles don’t fade away (逐渐消失) after they have grown up (长大), and they can’t deal with (处理) them and to make any progress (进步), it’s possible the kid has a learning disability.
Finding out you have a learning disability can be sad. You might feel different from everyone else. But the fact is that learning disabilities are pretty common. And if you have a learning disability, you can start getting the help you need to do better in school. But to make this special help really work, you’ll need to practice the new learning skills. It may take a lot of practice every day. That can be a challenge (挑战), but you can do it. Soon, you’ll make progress and enjoy the results of all your hard work: more fun and success at school.
1. What does the underlined word “genetic” mean in the passage?| A．变异的 | B．遗传的 | C．特殊的 | D．个别的 |
| A．It is a physical (生理的) illness. |
| B．It can be treated easily by doctors. |
| C．It always happens to only a few children who are lazy. |
| D．A learning disability needs new learning skills. |
| A．He/She always fails in exams. |
| B．He/She will always be laughed at by others. |
| C．He/She will enjoy more fun at school. |
| D．He/She will get into trouble in learning a certain subject. |

9 . Chinese astronauts gave a science lesson to millions of students on Dec 9, 2021. They did so from 400 kilometers above Earth, from the Tiangong space station. The three, Zhai Zhigang, Wang Yaping and Ye Guangfu, showed life in space and did experiments in gravity.
“It was the first lesson of the Tangong class, China’s first in space.” noted China Daily. “Its goal is to make more people know space science.”
“The lab of the space station has many conditions that the Earth lab does not have, such as the environment of weightlessness and radiation.” Wen Xin, a professor at University, told Xinhua. He said that important jobs for astronauts in the space station include research of cell growth and plant life.
In the lesson, Ye did experiments that had to do with cell growth in a weightless environment. He compared the growth and shape of cells in artificial gravity and zero gravity to study their changing rules in space. This was not the first time that China has tried to grow plants in space. As early as 2016, Chinese scientists grew rice on the Tiangong Ⅱ space lab to study how plants grow without an Earth-like environment.
Another experiment in the space lesson was shown by Wang Yaping. She showed how a paper flower “bloomed” on the surface of water in Tiangong space station. She explained that the surface tension of water becomes stronger in space due to zero gravity. Surface tension is like a “skin” of water. One of the examples of surface tension on Earth is that some insects can walk on water. Most of the time, gravity is too strong and it breaks the “skin”. But with zero gravity in space, some insects can use surface tension to “stand” instead of falling through water. Surface tension plays a key role in product development. Researchers are measuring surface tension to improve the quality of their products. Detergent effect can be improved with even lower amounts. Surface tension also has influence in medicine development.
Although the astronauts are thousands of miles away, their research really influence our life. Shi Yi, a teacher, told China Daily that the space lesson was “an eye-opening experience that would attract more students to study science”.
