Birds are the only animals that have feathers. Feathers are the coat a bird wears on its body, just like the hair most of other kinds of animals wear on their bodies. We, human beings, don’t depend on feathers or hair to keep us warm, as birds and animals do, we have our clothes. The feathers and shapes of the birds help us to tell one kind from another. Feathers come in beautiful colors.
Many birds use color to hide from enemies. This is called camouflage. All birds molt, but the ptarmigan molts twice a year. changing color to go right for the season. In winter, when snow is on the ground. it has white feathers. In spring, it molts an grows brown feathers that match up with the land, grass, trees or other conditions where it lives. When winter comes, it molts again and grows white feathers.
Besides feathers, birds can have good voices and are good at singing. Many birds. such as the robin, sing to send messages to other birds. Each type of songbird has its own song. By singing, birds show who they are and where their land is. In spring, many birds sing together loudly at daybreak. The sound they make is known as the dawn chorus, so-called “early morning singing of love” by many people in a Chinese yet simpler way.

【推荐2】Arctic fox(北极狐) is a kind of small fox that lives in the Arctic. It grows about 50 centimeters(厘米) long, not including its tail, 30 centimeters tall and weighs from 3 to 7 kilos.
The Arctic foxes are white or blue in color. The white ones are white in winter, but gray-brown in summer. The blue ones are blue-gray all year round. The Arctic foxes have long, thick hair that is called fur(毛皮). And the long fur covers their whole bodies, including both their cat eyes and rabbit feet, to keep them warm in the low temperature in the Arctic.
The Arctic foxes feed mainly on birds, birds’ eggs and other small animals. Teamwork is the way they look for food, and they don’t like to do that alone.
Baby Arctic foxes are very lovely. They don’t open their eyes until a week after their birth. For the first half of the year, their parents offer them food. They begin to look for food on their own when they are about six months old. The next year they can live alone.
Today the number of the Arctic foxes is becoming smaller and smaller, because people kill them for their fur to make beautiful coats for money. Something must be done to protect the Arctic foxes.

1 Protect wildlife habitat (栖息地).
Perhaps the greatest threat that faces many species (物种) is the widespread destruction (破坏) of habitat. Cutting down forests, farming, and development all result in loss of wildlife habitat. In areas where rare (稀有的) species live, habitat destruction can quickly force a species to extinction (灭绝). By protecting habitat, entire communities of animals can be protected together naturally.
2Reduce the threat (威胁) of invasive (入侵的) species.
The spread of non-native species has greatly reduced native populations around the world. Invasive species compete with native species for resources (资源) and habitat. They can even prey (捕食) on native species directly, forcing native species towards extinction.
3 Place decals (贴花纸) on windows.
It is reported that as many as one billion birds in the United States die each year because of collisions (碰撞) with windows. You can help reduce the number of collisions simply by placing decals on the windows in your home and office.
4 Slow down when driving.
Many native animals have to live in developed areas and this means they must move in human-living areas. One of the biggest obstacles (障碍) to them is that created by roads. Roads divide habitat and present a constant (不断的) risk to any animal attempting to cross from one side to the other. So when you’re out and about, slow down and keep an eye out for wildlife.
1. Is the greatest threat that endangered animals faces created by roads?2. How many ways to protect the endangered animals is mentioned in the passage?

The Blood Group Alphabet
Sometimes people lose too much blood from injuries or accidents. To save their lives, doctors must replace the lost blood. In an operation called a transfusion, doctors put blood given by healthy people into the veins(静脉)of the sick or injured person. But they must be careful. Although all blood looks the same, there are really different types of blood. Someone getting the wrong type of blood in a transfusion may become very sick or even die.
All blood is made up of red and white cells, and a liquid(液体)called plasma(血浆). It is the red cells that cause blood to be different types. On the outside of the red cells of some people's blood are proteins(蛋白质). Doctors group these proteins into two different classes, A and B. People with the A protein have Type A blood, while people with the B protein have B type blood. If someone happens to have both proteins, that person has Type AB blood. Some people don't have either protein, and their blood is called Type O.
If a person receives a transfusion of the wrong type of blood, the body senses the strange protein on the new blood cells. So the body destroys the new blood, and the patient goes into shock. For example, people with Type A blood will become very sick if they are given Type B protein because their bodies try to destroy the strange Type B protein. People with Type O blood have no proteins on their cells, so their bodies will destroy both Type A and Type B blood. They can only receive Type O blood. But people with Type AB blood have both proteins, so they can receive Type A, Type B and Type AB blood. These people are called Universal Receivers. People of any type can receive Type O blood because it has no protein for the body to fight against. So Type O people are called Universal Donors.
Doctors are always careful to test blood for its type before it is used in a transfusion. Although the wrong type of blood can be harmful, the right type can save a life.
1. What is the blood made up of?2. How many classes do doctors group the proteins into?
3. What type of blood does the person have if someone doesn't have either protein?
4. Why can people with Type O blood only receive Type O blood?
5. Are Type AB people called Universal Donors?
【推荐2】March 22 is World Water Day. The theme last year was “groundwater”. We can’t see groundwater. It’s under our feet. But it plays an important role in our lives. About 98 percent of Earth’s fresh water is groundwater. It is 60 times as plentiful as the fresh water in lakes and rivers. On the 31st World Water Day this year, let’s keep focusing on the water resource.
The world’s water moves between lakes, rivers, oceans, the air and the land in a cycle. It is a continuous process, with no beginning or end. The sun heats the water. This changes water into vapor(蒸气). It is called evaporation, which makes the first step of the Water Cycle. When the water vapor reaches up in the sky, it turns into tiny drops of water. These water drops come together to form clouds. This process is called condensation. When the cloud becomes too heavy and it can’t hold any more water inside, it will give out rain or snow. This is known as precipitation.
Now, more and more countries are facing the problem of water shortage. There are some reasons for this. Firstly, with the population increasing fast, more water is needed. Secondly, climate change makes things worse. There are other reasons for water shortages. For example, water pollution makes it harder to get clean drinking water. Factories and farms don’t use water efficiently.
News “Dear customer, our city has been facing a serious drought(干旱). Please try your best to save water. Thanks for your understanding and support.” In December, 2021, people in Shenzhen, China got this message on their phones. At the same time, water ran more slowly from their taps. |
In the face of serious water shortage, we should raise awareness(意识) of protecting water. Meanwhile, we need to take action to save water. Let’s take a look at how Timmy saves water every week. (L=Litre)

The traditional Chinese lunar calendar(阴历) divides the year into 24 solar terms(节气). Lichun, the first of the 24 solar terms, lifts the curtain(窗帘) of spring. After that everything turns green and is filled with energy. Here are some things you might not know about Lichun.
As a solar term, Lichun entered people’s lives in the Spring and Autumn period. At that time, there were eight solar terms. According to some experts, the 24 solar terms were used for the first time in books during the Western Han Dynasty, when people set Lichun as the Spring Festival.
Every Lichun, people like to wear a swallow made of colorful silk on their chests (胸部). The swallow is a sign of spring and a symbol of success, wealth and happiness.
In China, it is said that the egg can be set upright on the first day of Lichun. It is believed that if someone can make the egg stand on the first day of Lichun, he will have good luck in the future.
In many parts of China, people follow the custom of “biting the spring” on the first day of Lichun. They eat spring pancakes, spring rolls (春卷) and so on.

Books written in the Gothic(哥特式) style are popular all over the world. A feature of these books is that they usually mix fiction, horror and death. They have romantic scenes at times. Gothic style books first appeared in the late 1700s in Great Britain. They were especially popular during Victorian times(1837-1901). Many of s novels we read today, such as Jane Eyre and Frankenstein, are from that time period.
Dr Jekyll and Mr. Hyde by British author Robert Louis Stevenson(1850-1894) is a famous Gothic novel.
One of the story's most important characters is Dr Jekyll, a doctor with a kind heart who lives in London. He and his close friend Mr. Utterson often have dinner together. But one day, Utterson notices Dr. Jekyll behaving strangely after asking him about a crime that happened outside Dr. Jekyll's house. He says that a young girl had been killed by a man. The police believe that the man may have committed many crimes, but they couldn't find any clues. Mr. Utterson shows great interest in the case, only to find out that the murderer is Dr Jekyll himself.
In fact, Dr Jekyll had invented a kind of medicine that turned him into Mr. Hyde, an evil (邪恶)man. He believed that all humans have an evil side. He wanted to see if he could move the evil part away from the good part.
In the book, the author shows human's dual(双重的)nature. People can have both an evil side and a good side, just like Dr Jekyll: He looks kind on the outside, but he can also be a cold-blooded murderer on the inside. The author uses detailed comparisons and, descriptions to explain the way both sides of Dr Jekyll work Because of this, the novel turned out to be a successful one and has been spoken highly of by thousands of millions of readers since it was published. It has been made into over 120 stage and film versions(版本) so far.
