Plants are very important. It is because plants can make food from air, water and sunlight. Animals and man cannot make food from air, water or sunlight.
Animals can get their food by eating plants and other animals. Man gets his food by eating plants and animals, too. So animals and man need plants to live. This is why there are so many plants around us. There are two kinds of plants: flowering plants and non-flowering(无花) plants.
Almost all the plants around us are flowers and fruit. Non-flowering plants don’t grow flowers. You can’t see many non-flowering plants around you. If you look carefully at the plants around you, you’ll find that there are so many kinds of plants. Some plants are very big and others are very small. Most of them are green. We can live on the earth because of the plants around us.

【推荐1】“Wash your hands often and carefully, with soap and water!” We often hear this, but do you follow it? As we know, washing hands is important to our health. There’s even a day to make us do it and know more about its importance. It is Global Hand-washing Day and it’s on October 15. During the outbreak of COVID-19 this year, washing hands plays an even more important role in preventing the virus (病毒) from going around.
People think of Doctor Semmelweis from Hungary as the first person to find out the good results of hand washing. He pointed out the importance of hand washing to doctors, because they often worked with people who are seriously ill. And he saved a lot of people’s lives by telling doctors to wash hands with chlorine (氯) before each examination (检查). After that, the number of dead patients became much smaller.
You might think everyone would be excited, because Dr. Semmelweis solved the big problem. But in fact, things were quite different. Although Dr. Semmelweis kept asking doctors to wash their hands with chlorine, not every doctor accepted (接受)his idea. Some even sent him to a mental hospital. His idea became really popular years after he died.
Now that washing hands is of great importance, we should do it as carefully as we can. What’s more, it’s necessary to wash our hands in right ways.
1. What does the underlined word “preventing” mean?| A．Stopping. | B．Sharing. | C．Choosing. | D．Helping. |
| A．Building some hospitals in Europe. |
| B．Taking good care of new babies in hospitals. |
| C．Finding washing hands could do some good. |
| D．Spending Global Hand-washing Day in a special way. |
| A．He lost his life on October 15. |
| B．He came from the United States. |
| C．Not every doctor listened to him at first. |
| D．He didn’t like to wash his hands with chlorine. |
| A．How to stay away from all kinds of viruses. |
| B．How to keep healthy in everyday life. |

【推荐2】Winter weather has returned to northern areas of the world. In much of the United States, winter means the return of snow.
Snow is a form of frozen water. It contains many groups or very small ice particles called snow crystals（晶体）. These crystals grow from water particles in cold clouds. They usually grow around a piece of dust. All snow crystals have six sides, but they grow in different shapes. The shape depends mainly on the temperature and water levels in the air. The shape of a snow crystal may change from one form to another as the crystal passes through levels of air with different temperatures. Snow contains much less water than rain. About seventy-five centimeters of snow has as much water as two and a half centimeters of rain.
Generally, the color of snow and ice appears white. This is because the light we see from the sun is white. Most natural materials take in some sunlight. However, when light travels from air to snow, some light is sent back, or reflected（反射）. Snow crystals have many surfaces to reflect sunlight. It is this light that gives snow its white color.
Much of the water we use comes from snow. Melting（融化）snow gives water to rivers and crops. Snowfall helps to protect plants and some wild animals from the cold. Fresh snow is made largely of air which is kept among the snow crystals. Because the air has trouble moving, the movement of heat is greatly reduced. However, snow is responsible for the deaths of hundreds of people in the United States every year. Many people die in traffic accidents on roads that are covered with snow or ice.
1. Why is snow dangerous according to the passage?| A．People can freeze to death in it. | B．It makes roads difficult to drive on. |
| C．It stops people hunting wild animals. | D．It makes it difficult for fresh air to move. |
| A．Because ice is a white colour. | B．Because it has many surfaces. |
| C．Because it reflects sunlight. | D．Because clouds are white. |
| A．It covers roads with snow and ice. | B．Snow creates fresh drinking water. |
| C．It hides them from human beings. | D．It keeps them warm in cold weather. |
| A．2 and a half centimeters of rain. | B．Levels of air with different temperatures. |
| C．Water particles and dust. | D．Cold clouds in the air. |
【推荐3】Ask people what they know about the Dead Sea(死海) and most will tell you that it's impossible to sink(下沉) when you're swimming in it. But not everyone knows why.
The Dead Sea is an inland(内陆的) lake 67km long by 18km wide in the Middle East. The Jordan River is the main source of the Dead Sea water.
It is about 430m below sea level, the lowest point on the surface of the Earth. The water level has been dropping even lower for the past 60 or so years, mostly because river water is being used elsewhere rather than flowing into the Dead Sea. It drops about 1m each year.
It's a popular place for people to have a holiday, partly because it's in the desert(沙漠), which means lots of hot, sunny days.
Why can't you sink in the Dead Sea? The water of the Dead Sea is full of salt, which makes it much denser(密度大的) and heavier than freshwater. If you swim in it, you will float(漂浮) very easily.
Travel writer Celeste Mitchell described her experience trying to go for a swim in 2017: "The water is only past my knees when I realise no matter how hard I try, I can't force my feet to the bottom. I try my best to push my body deeper, but despite my best efforts, I stay afloat(漂浮的) ."
1. How long is the Dead Sea?| A．60 kilometers. | B．67 kilometers. | C．18 kilometers. | D．43 kilometers. |
| A．Because the view is beautiful there. |
| B．Because it's different from other lakes. |
| C．Because it's a great place for swimming. |
| D．Because it's in the desert and the weather is sunny and hot. |
| A．The water of it is full of salt. |
| B．The water of it comes from the Jordan River. |
| C．The water lever has been dropping even lower. |
| D．The water of it is less denser and heavier than freshwater. |
| A．in a film poster | B．in an advertisement |
| C．in a sports newspaper | D．in a science magazine |
Another tea-drinking country is England， the late afternoon is “tea time”. Almost everyone has a cup of tea then. If you are a friend of the family， you may drop in for tea without an invitation or telling that you are coming. Very often it is not served at a table. The English usually make tea in a teapot and drink it with milk and sugar. They also eat cakes and cookies at tea time. This is so—called “afternoon tea”in England.
In America ， people drink tea mostly at breakfast or after meals. Americans usually use tea bags to make tea. In summer， many Americans drink cold tea—“iced tea.” Sometimes they drink iced tea from cans， like soda.

【推荐2】No one knows when the first kite was made. The first record of a kite was more than 2,000 years ago in China. Han Xin, the leader of an army, wanted to bring down a king. He decided to dig a tunnel (隧道) into the king’s palace. He flew a kite over the wall of the palace to make sure the length of its string (线).
In this way, he could determine how long the tunnel should be. His men in the tunnel took the kite string with them. When they reached the end of the string, they knew it was time it was time to dig up.
Kites have been flown in Japan for hundreds of years. In the 1700s, kites were flown in autumn to give thanks for a good harvest.
They were also flown to send good wishes to couples who had their first son. Today in Japan, kites are often flown as part of a celebration, such as the beginning of a new year. And kite festivals are held each year in many parts of the country.
Kites have been used for scientific purposes in the western world. In 1752, Benjamin Franklin tied a key to a kite and flew it in a storm to find out that lightning was a form of electricity.
In the 1890s, Lawrence Hargrave invented the box kite to test ideas about flight. From 1898 to 1933, the United States Weather Bureau (气象局) used box kites to collect weather data. The Wright brothers also experimented (试验)with kites. What they learnt helped them make the first airplane flight in 1903.

There was a young woman who took great pride in her flower garden. She was raised by her grandmother who taught her to love and care for flowers.
One day, while she was looking through a flower list she often ordered from, a picture of a plant caught her eyes.
“I have to have it,” she said to herself, and she ordered it at once.
When it arrived, she already had a place prepared to plant it. She planted it at the back of her yard. It grew well, with beautiful green leaves all over it, but there were no blooms. Day after day she continued to water it, feed it, and she even talked to it trying to make it bloom.
One morning weeks later, when standing before the vine, she felt very sad that her plant had not bloomed.
It was at this point that her neighbor, whose yard joined hers, called over to her. “Thank you so much! You can’t imagine how much I have enjoyed the blooms of that vine you planted.” The young woman walked through the gate into her neighbor’s yard, and sure enough, she saw that on the other side of the wall the vine was filled with blooms.
Sometimes one may not see the good result of his effort, but that doesn’t mean it isn’t successful.

| D．So her flower garden was the best. |
| E．She felt very proud of her garden full of many kinds of flowers. |
