Do you think of white when someone talks about a polar bear? In fact, the polar bear does not have white fur. It just appears to be white. Polar bears have a very good sense of smell. It helps them to find food. During summer, polar bears sleep longer, because they are able to find food more easily at night. Usually, after a meal, polar bears have a short sleep. A polar bear can have 2 to 3 babies at a time. They don’t leave their mothers until they are about 2.5 years old.
However, polar bears will die out soon because of people. There are about 20,000 polar bears in the world. The ones that are left are trying to survive today. The number of polar bears is becoming smaller and smaller because of the loss of sea ice—polar bears mostly inhabit (居住于) the sea ice, not the land ice. This is happening because of global warming (全球变暖), pollution, hunting and so on.
Ordinary people don’t care, but great people have the power and want to save tigers, fight for giant pandas and save polar bears. Ordinary people will wait, but great people will find a new world. Join me and save the polar bears, and, of course, the tigers, he giant panda and...

【推荐2】In my backyard, there stands a strong and thick tree that has watched me grow up. It offers shade (阴凉处) on hot summer days and a home to many birds. I remember climbing it up as a child, feeling like I was reaching for the sky. The tree and I, we have always been there for each other.
One day, there would be a big storm. I worried about my friend. Papa said we should help it by tying ropes for support. Working together, we tied ropes around the tree. After the storm passed, the tree stood strong, and I learned that just like the tree, nature needs our care, too.
I started collecting rainwater in a bottle nearby. The tree seemed to love it, as its leaves grew greener. I also planted flowers around it, and bees came to visit, helping them grow better. My friends from school helped me make bird feeders, which hung from the branches (树枝), feeding the birds that sang their thanks every morning.
The tree taught me that we depend on nature, and nature depends on us. By respecting and supporting it, we can both live well. Now, more than ever, I understand our special relationship—we are one with the world around us, and together, we can make it a better place.

【推荐1】On April 16th, 2022, Shenzhou-13 and its crew returned to Earth successfully.
As you may expect, life in space is much different from life on earth. So of course people need some time to get used to it. How do they live, work and play up there?
Space food keeps getting more like the food we eat at home on the earth. In the past, astronauts could eat only freeze-dried food. But now the space station has water, microwave(微波炉) ovens and fridges. So astronauts can eat more usual kinds of food, like fruit, vegetables and ice cream!
All people in the ISS(国际空间站) have their own rooms. There’s no gravity(重力), so they have to attach(依附于) themselves to their beds, or they’ll float(漂浮) away! That may seem like a hard way to sleep, but astronauts say that sleeping in space is actually not too bad.
This is more important in space than on Earth. There’s not much gravity in space. Astronauts don’t stand up, sit down or walk in space, so their muscles don’t have to work much. They exercise on bikes and other machines for about two hours every day while they’re in space. In this way, they can still keep strong and healthy when they get back home.
Easy things like brushing your teeth can be hard in space with low gravity. Water doesn’t flow out of a tap. It floats in a bubble(水泡)! Astronauts use a special hose(软管) to take showers. And when they’ve finished, they use a vacuum(真空的) hose to suck the dirty water off of their bodies. How do you go to the toilet in space? They use a special “air toilet”. It uses air, not water, to take everything away.
What do astronauts do when they aren’t working? They read books, play cards, listen to music or send e-mail to their friends and family. Sometimes they just sit and look out of the window. Doesn’t it sound like much fun? But what if you could see planet Earth out of your window, with a sunset or sunrise every 45 minutes?
1. Which of the following can be the title of this passage?| A．Life in Space. | B．Space Food. | C．Showers in Space. | D．A Visit to Space. |
| A．keep themselves warm | B．prevent themselves from floating away |
| C．have a good sleep | D．feel better |
| A．they have nothing to do in space | B．they are told to do so |
| C．they do so to keep healthy | D．they do so to prevent them from sleeping |

【推荐1】In English, “as dead as a dodo” means someone or something is totally dead. But the dodo, a short and far bird that has been disappeared for hundreds of years, may not be dead anymore.
US company Colossal Biosciences said it would try to bring the dodo back to life. The bird used to live on the island of Mauritius (毛里求斯) in the Indian Ocean until the 17th century. So the best place to bring back dodos would be Mauritius. Bringing back dodos brings benefits to the plants and animals that have already lived there.
The company has found the genetic code (基因序列) of dodos from their dead bodies. To make currently living animals close to dodos, DNA should be changed. The Nicobar pigeon (尼柯巴鸠) will he used as the genetic base for the dodo.
The company also has plans for other extinct (灭绝的) animals, such as mammoth (猛犸象). They believe that mammoths could help with climate change because they turn the wet tundra (苔原) into dry grasslands by eating the grass.
However, some people don’t like the idea. In their opinion, there is more need to protect today’s species than focus on animals of the past. From my point of view, it’s always a wise idea to value what we have instead of the things we have lost.
1. What is the writer’s main purpose of writing Paragraph 1? ________| A．To present an English phrase. | B．To give an example. | C．To lead into a topic. |

【推荐2】The air is thin here in Tibet and we have to rest several times on the short hike from camp. To our left, snow-covered mountains disappear into clouds that seem almost close enough to touch. On the wide grass in front of us, we can just see a group of beautiful animals. This is why we are here—to watch Tibetan antelopes (藏羚羊).
Tibetan antelopes live on the grass of Tibet, Xinjiang, and Qinhai. Watching them move slowly across the green grass, I am shocked by their beauty. I am also reminded of the danger they are in. People hunt for their expensive fur.
My guide is Zhaxi, a villager from Changtang. He works at the Changtang National Nature Reserve (保护区). The reserve is a safety home for the animals and plants of northwestern Tibet. To Zhaxi, the land is sacred (神圣的) and protecting the wildlife is a way to life. “We are not trying to save the animals,” he says. “In fact, we are trying to save ourselves.”
The 1980s and 1990s were bad times for the Tibetan antelope. The number dropped by more than 50 percent. Hunters were killing antelopes to make money. Their homes were becoming smaller as new roads and railways were built.
In order to save them, the Chinese government put it under national protection. Zhaxi and other volunteers watched over the antelopes day and night to keep them safe. Bridges and gates were added to let the antelopes move easily and keep them safe from cars and trains.
The antelope number has risen and in June 2015, the Tibetan antelope was no longer endangered. The government, however, does not intend to stop the protection programmes, since the threats to the Tibetan antelope have not yet been gone.
In the fine evening, I drink a cup of tea and watch the stars. I think about the antelopes and what Zhazi told me. If we really want to save the earth, we must change our way of life. Only when we learn to be in harmony (和谐) with nature can we stop being a threat to wildlife and to our earth.

【推荐3】Crested ibises (朱鹮) are one of the oldest birds (鸟) in the world. They live in Asia. The beautiful birds have disappeared (消失) for a long time. But on May 23, 1981, Chinese scientists found and saved them. Here is a story of them.
In the past, there were lots of crested ibises in Asia. But in 1960s, people cut down trees. So crested ibises lost their homes and started to disappear. Chinese scientists were worried about this.

Then, on May 23, 1981, Liu Yinzeng and his team found the crested ibises in Hanzhong. “That night, I saw a crested ibis fly across the sky. We ran after it and found six more crested ibises in the forest,” Liu said.
After that, scientists started studying and saving the birds. They asked people not to kill the birds or cut down trees. They also helped birds to get more babies. Over the past 42 years, people saw the number of the crested ibises grow from 7 to over 9000.
