Have you seen koalas (考拉) in a zoo? They are very cute. The koala is a small bear-like, tree-dwelling animal, which averages about 9 kilograms in weight. Its fur is thick and usually ash gray. They come from Australia. They do not come from any other place. Today koalas are mainly found in Queensland, New South Wales, Victoria and South Australia. People in Australia want to protect them.
Now there are about 100,000 koalas in Australia. But there are fewer and fewer of them all the time. Some koalas are getting sick. The sickness makes them not able to see. It also makes it hard for them to have babies. Besides, Koalas also live in societies, just like humans, so they need to be able to come into contact with other koalas. It is because of this they need to have areas of suitable forest, which are large enough to support a healthy koala population and to allow expansion by raising young koalas.
But People are building more houses and roads too. This means koalas do not have as many places to live. Some people want the government to do more to take care of the koalas.
People should think about animals. They should take care of them. Then the cute animals will stay alive!

【推荐1】Migratory birds (候鸟)fly to different places during different seasons. They may fly day and night for months at a time. During this long journey, when and how do they sleep?
In 2016, some scientists studied a group of frigate birds(军舰鸟)during a ten-day flying journey. They found that frigate birds can sleep while they’re flying! According to this study, these birds take two kinds of short sleep.
The first is called Rapid Eye Movement(REM, 快速动眼)sleep. It is the deepest period of sleep. For humans, REM sleep can continue for many minutes. For flying birds, however, REM sleep continues for only a few seconds(秒). Even so, this period of sleep is still very important for their brain health.
The other kind of short sleep is “half sleep”. Frigate birds put only half of their brain to sleep, while the other half stays awake. The eyes of these birds are always connected to the waking part of their brain. In other words, they sleep with their eyes open. It is still a little dangerous to take such a short sleep, though. So, these birds prefer to stay awake most of the time. Before reaching land, they spend less than three percent of their time sleeping.
However, not all migratory birds sleep in this way. Many will make several stops on their way to get a good rest. Some stay completely awake for their whole journey. Alpine Swifts(高山雨燕), for example, can keep flying for nearly 200 days. There are few signs of these birds sleeping during their long trips.
The sleeping habits of birds are different from species(物种) to species. This makes the study of migratory birds very exciting for scientists. In the future, we may learn more amazing things about these animals!

【推荐2】Almost all animals need to sleep to stay healthy. But sleeping can also be dangerous because other animals may hurt those who are sleeping. This leads to many different ways of sleeping that help them stay safe. Some of these ways may surprise you!
Almost all bats sleep upside down. They hang from a branch of a tree or the ceiling of a cave. Up high, bats are safe from most other animals. If they are in danger, they just fly away.
A dolphin sleeps with just half its brain at a time. It must stay awake to breathe and to watch for danger. Dolphin mothers and babies can go without sleep for as long as two months to stay safe.
Some ducks sleep with just half their brains, too. These ducks often sleep in a line. The ducks at both ends help to keep the group safe. They keep one eye open to watch for danger. The ducks in the middle sleep deeply with both eyes closed.
Seals breathe air, but that doesn’t stop some of them from sleeping underwater. They hold their breath and dive deep to sleep for up to twenty minutes at a time. Sleeping deep under- water helps these seals stay safe from animals that hunt them near the surface.
Horses often sleep standing up. Their legs lock in place so they don’t fall over. If a horse is lying down, it needs a long time to get up. A horse can run from danger more quickly if it is already standing.
A flamingo can sleep while standing on one leg. The standing leg locks so it stays straight. The other leg remains close to the flamingo’s body. Its head rests on its back. A flamingo lives (and sleeps) near many other birds to stay safe.
Some seabirds can sleep while they fly. These large birds spend most of their lives over the ocean. They are in danger on the water, but they are safe in the air They fly for many hours without flapping(拍打)their wings. Sometimes they sleep while they are flying.

When studying a map of China, have you ever noticed the Mu Us Desert(毛乌素沙地)in the northwest? If you haven’t, then you probably never will. That’s because the desert is disappearing (消失).
You might wonder: Why is this happening? Who is the “killer”? Well, this is not a murder(谋杀)story. It is, the result of years of afforestation(无林地造林)efforts.
The Mu Us Desert used to be one of the largest deserts in China. Sandstorms(沙尘暴)were common in northern Shanxi. As a result, lots of people had to leave their homes.

In Yulin, there are many other sandstorm fighters. One of them is Guo Chengwang. In 1985, the government encouraged local people to plant trees. So he started to plant trees in his village. Guo is now over ninety years old. His children, grandchildren and great-grandchildren are still going on doing the job. The family has turned 30 km² of desert into woods.
These trees have make a difference. In Yulin, the number of sandy days has dropped from 100 in 2000 to 10 now. With the sandstorm fighters’ continuing efforts, the Mu Us Desert will be gone. Our country is becoming greener and lovelier.

【推荐2】Farthing is moving indoors,where the sun never shines,where rain never falls and where the weather is always proper. The perfect crop field could be inside a windowless building with controlled light, temperature,wetness,air quality and nutrition. It could be in a building in New York or in a desert in Sahara.
The world is already having trouble feeding itself. Half the people on Earth live in cities,and nearly half of those are hungry or ill﹣fed. Food prices are buffeted by,floods and the cost of energy required to plant, harvest and transport it. And prices will only get more changeable. Farmers in many parts of the world already are using water available to the last drop. And the world is getting more crowded by mid﹣century,the world's population will grow front 6. 8 billion to 9 billion.
To feed so many people may require more farmland , as a result , forests and wilderness(荒地)are becoming fewer and fewer.
Gertjan Meeuws has taken the idea of a greenhouse a step further, growing vegetables and houseplants in enclosed(封闭的)environments. In their research station , water flows into the fields when needed,and the temperature is kept the same. Lights go on and off, creating similar day and night,but according to the needs of the plants.
A building of 100 square meters and 14 layers(层)of plants could provide a daily diet of 200 grams of fresh fruit and vegetables to the entire population of Den Bosch, about 140,000 people. Their idea isn' t to grow foods that require much space,like corn or potatoes. Here sunlight is not only unnecessary but can be harmful. Plants need only specific(特定地)light to grow. Their growth speed is three times faster than under greenhouse conditions. They use about 90 percent less water than outdoor agriculture. And city farming means producing food near the citizens, and there's no need to transport it long distances.

【推荐3】In the Americas, Asia, and Africa there’s a special kind of forest called the cloud forest. Cloud forests can be found in the clouds on the mountains.
Like rainforests, cloud forests experience rainfall, but they also catch water straight from the air. Water condenses (凝结), you’ll hear the drop of water, even if it’s not raining. The water caught is clear and unpolluted (流动) through the ground into rivers.
Some people call cloud forests water towers, because they are so important in providing water for nearby villages and cities. But it’s not just humans who depend on cloud forests. They are also home to a lot of animals and plants.
Cloud forests are very special places. But they face problems. Local poor people clear the forests so that they can grow crops. They also hunt endangered animals for meat, and cut down trees to heat their homes and cook. Farmers convert (改造) the land so that they can grow fruits, and coffee beans.
Once cloud forests are cleared, the harm can be irreversible (不可逆转的). Many species which are important to the ecosystem (生态系统), goes away.
Cloud forests are very valuable. With laws to protect them, we might be able to save them before it’s too late.

【推荐3】Zhang Ming, a college student from Shandong, created a 9-page “WeChat guide”. With drawings and simple words, the step-by-step guide explains how to send messages, take pictures and make video calls. Zhang made the guide for his parents. “My parents are getting old. They need an easy way to learn how to use new technology.” He said.
Zhang’s experience is common nowadays. Worldwide, 40 percent of parents learn about new technologies, including computers, mobile Internet and social media, from their children, according to a study from the International Communication Association in 2014.
Parents used to teach their kids about almost everything. Now for the first time, the teachers become the students, and the students turn into the teachers.
The change of roles comes from the rapid development of society and technology, says Zhou Xiaohong, a sociology professor from Nanjing University. Zhou said the Internet and other forms of media give children ways to get information besides from asking older generations(长辈). Therefore, in the age of information, it’s possible that children know more than their parents do.
According to the China Internet Network Information Center(CINIC), 56.7 percent of Internet users and 67.2 percent of social media users in China are under the age of 30. The younger generation usually acts as alinkbetween their family and the new environment. But when they teach their parents new technologies, parents can connect to the new world by themselves, noted Zhou.
In Zhang Ming’s eyes, teaching his parents about WeChat brings him closer to his parents. “People can communicate more by using new technology. Why should we keep our parents out?” said Zhang.
