【推荐1】Who wants to carry a bulky bag to school? No children. Nobody wants one shoulder to be lower than the other, and paining, too. In India, most of people would look at the reduction(减少) of textbooks as a way out. But in a country like America, there are always more choices. A company called goReader has created a “school bag” which is the size of a laptop computer, weighing about 1.5 kg. The goReader has a color screen and can “hold” all the textbooks that a student may need, says a report in The Asian Age newspaper.
The company plans to work closely with the publishers(出版商) of textbooks so that these books can be supplied on the Internet. All the students will have to do is to download their textbooks from the Internet. Taking notes and marking important parts of a lesson can be done just as lots of students have done on their textbooks before.
At present, the plan is being tested out in a university. Richard Katzmann, the owner of this company is having his creation tested at Chicago's DePaul University, where he studied. Does that mean it is goodbye to the new paper, and the smell of the black ink?

Because of the new technology(技术), in 2014, bike-sharing came into people’s lives. You find an Ofo or Mobike bike, scan its QR code, then the bike is yours. After using it, you can park the bike almost anywhere. According to a research, at the first week of this year, there are 5.85 million active users of Mobike while Ofo had 1.4 million active users. Bike-sharing has become more and more popular across China’s major cities and much news has reported it.

However, there are some problems caused by bike-sharing. On one side, bike-sharing makes it very convenient of people traveling. You can find a bicycle anywhere at any time when you want to go out for a cycling, and the price of one trip is very low. It can save time for people. On the other side, its management is not perfect. Even kids can open the lock and ride the bicycle, it is surely very dangerous. What’s more, some people break it, like throw it to the river or destroy the QR code above it.

In fact, these problems are also showed by bike-sharing systems abroad. Now, Chinese are trying to solve these problems. For example, Mobike sets a 100-point credit score(信用分数) for each user. Once a score drops below 80, bike rental(租金) is increased to 100 yuan per 30 minutes, which is 0.5—1 yuan now.

【推荐3】When we think of paper, we think of newspapers and books. But there are many other uses. Only half of the world’s paper is used for books and newspapers.

Paper is very good for keeping you warm. In Finland, it is sometimes -40℃ in winter. The farmers wear paper boots (靴子) in the snow. Nothing could be warmer.

Each year, more and more things are made of paper. We have had paper cups and plates for a long time. But now we hear that chairs, tables and even beds can be made of paper. Besides paper boots and shoes, you can wear paper hats, paper dresses and paper raincoats. When you have used them once, you may throw them away and buy new ones.

The latest use of paper seems to be paper houses. These are not small houses for children to play in, but real, big houses for people to live in. You can buy a house with three rooms for about 500 dollars.

1. Most of the world’s paper is used to print newspapers and books.
2. Nothing could be warmer than paper boots when the temperature is -40℃ in Finland.
3. After you use a paper raincoat, you may throw it away.

【推荐1】Teenagers believe anything is possible if they study hard. But they often forget to think about healthy diets, enough sleep time and exercise. In fact, these things are really important for them to keep healthy.

It is important for teenagers to get enough energy (能量). Teenage girls need about 2,200 calories a day while boys need a bit more—doctors suggest 2,800 for teenage boys. 50% of their calories should come from healthy food—rice, vegetables and fruit. People often say an apple a day keeps the doctor away. Teenagers also need to drink a lot of water, 6 to 8 glasses a day. Drinking enough water will improve their skin.

Teenagers usually need eight to ten hours’ sleep at night, but many Chinese teenagers do not get enough sleep. A report shows that without a good night’s sleep, teenagers seem to be weaker than they should be. Too much homework is not the only reason why teenagers stay up late. Some watch TV or play computer games late into the night. Teenagers should develop good study habits. So some clever students never study late, but they are able to work well in class.

Exercise is something that can help them. Experts suggest that teenagers should spend at least 30 minutes exercising a day, five times a week. They will feel relaxed when they exercise. It can even help them sleep better at night.

【推荐2】Last April, Runway AI, a New York company introduced technology that let people make videos by typing a sentence into a box on a computer screen. The several-second videos were not clear.

Just 10 months later, another company OpenAI has developed a similar system that can create videos seemingly from a Hollywood movie. It shows a short video created in minutes: a woman is walking down a street. The technology could speed the work of seasoned movie-makers, but make less experienced digital artists lose their jobs. They call this system Sora.

However, Sora is not perfect. Sometimes, things like shop signs in the videos don’t make sense. Although it is good at getting details right, it can still make mistakes, like making the crowd’s feet look strange in the street video.

Despite (尽管) these challenges, Sora has a lot of possibilities. Models like Sora can change things by making videos in real-time (实时). This can be a big deal for things like video games and help the AI market grow even more. But to make this happen, we need a lot of computing power. Making just one second of video needs a lot of frames (电影画面的一帧), but present models take a long time to process each frame.

The company has not made Sora open to the public yet…

【推荐3】The world’s largest rainforest, the Amazon rainforest(亚马逊雨林), covers 40% of the area of South America. It makes about one fifth of Earth’s oxygen(氧气). People call it “the lungs(肺) of our earth”.

However, the Amazon rainforest is in danger now. A large fire happened there. It lasted for 22 days and ended on August 27, 2019. In fact, there are a large number of fires in the rainforest this year. Between January and August, there were over 74,000 fires. Most of the fires came from people’s activities.
