To change their city’s bad traffic, students at the National Polytechnic Institute of Cambodia (NIPC) have designed a new type of manned (载人的) plane. It is from a rather usual furniture—a school chair. The group hope to use it to carry people around capital city and even help fight fires.
With eight propellers (螺旋桨) and a school chair for the pilot’s seat, the plane was developed on the outskirts (郊区) of the capital.
“We wanted to solve some problems for our society by making a taxi plane and…inventing for firefighters,” said Lonh Vannsith, 21, the pilot of the plane. They hoped it could reach the upper floors of a building to bring a hose (软管) where a fire truck could not reach.
It took three years of research and development and cost around $20,000 to build. The plane can carry a 60- kilogram pilot and fly for about 10 minutes for a distance of 1 km. When manned, the plane now only rises to as much as four meter. The team plans to improve the design to allow it to take more weights, as well as fly further and more smoothly at a higher level.
“The project faced delay (延期) because of the international transport. Many parts of the plane had to be ordered from abroad,” said Sarin Sereyvatha, who is NPIC’s head of research and development technology.
“Generally, if we make one plane, the cost is expensive but if we make them to sell on the market, the cost will go down,” said Sarin.

【推荐1】ChatGPT, a smart AI chatbot（聊天机器人）tool, has bee very popular all over the world in the past months. According to a US survey of more than 1, 000 students, over 89 percent of them have used ChatGPT to help with a homework assignment（任务）.
Developed by US company OpenAI, ChatGPT is a powerful tool. You can ask it to write stories and emails, create recipes（食谱）, translate languages, and answer all kinds of questions.
Some schools in the US, Australia and France have banned（禁止）the use of ChatGPT. In the US, for example, New York City public schools banned students and teachers from using ChatGPT.
The move comes out of worries that the tool could make it easier for students to cheat on assignments. Some also worry that ChatGPT could be used to spread inaccurate（不准确的）information.
Apart from bans, teachers are making changes to their classes to stop the use of ChatGPT. Some college teachers in the US try to include more speaking exams and handwritten papers instead of typed ones.
However, not all schools say “no” to ChatGPT. Some Canadian universities are drafting policies（起草规章制度）on its use, for both students and teachers. They have no plans to completely ban the tool so far.
Bhaskar Vira, pro-vice-chancellor（副校长）for education at the University Cambridge in the UK, said that bans on AI software（人工智能软件）like ChatGPT are wise. “We have to know that AI is a tool people will use,” he told the school newspaper the university. What we need to do is “change our learning, teaching and examinations. That way, we can have integrity（诚信）while recognizing（认可）the use of the tool”.

【推荐2】Kite flying is the sport of sending up into the air, by means of the wind, a light frame covered with paper, plastic or cloth. The frame can be one of many different shapes and is attached to a long string held in the hand or wound on a drum. Kites have a long history of practical application and many different types of kites have been developed to serve various purposes.
The ancient Chinese used bird-kites to carry ropes across rivers and valleys. The present folding kite which will dive excitingly is an improved type of such a kite. With its long flat body and single pair of bird-like wings, it looks just like a large bird in the air. The modern version is usually made of tissue-paper rather than the traditional silk.
Man-lifting kites were developed in ancient times, again by the Chinese, for getting information from walled cities and army camps. In fact, as recently as World War II, German U-boats (德国U型潜艇兵) flew kites from their towers to lift people into the air to watch the land. These kites, which are no longer in existence, were made of light-weight cloth. They were much larger and stronger than the Chinese ones. Their design, however, was simply that of the cutter kite. Smaller in size, this type of kite is still very popular as a toy for children, being easy to make with a diamond-shaped frame, no wings and brown-paper covering.
Box-kites are another type of kites found in toy shops today. The first box-kite, named for its box-like body, was developed in the nineteenth century to test theories of flight and this type of cotton-covered kite greatly led to the success of early planes. These kites are the ancestors of a heavier version of the box-kite, which consists of two main sections, placed side by side. Developed for the peacetime purpose of fishing in strong sea wind, it is the only modern kite described which has practical value. A long-lasting plastic material has to be used for this kite, which carries fishing lines.

Cambridge University’s “doctor of chocolate”
Cambridge University is looking for someone to study the method of keeping chocolates in hot weather. It is a sweet job for a sweet tooth. However, the person needs to be good at maths. Chocolate has a melting (融化) point close to our body temperature. For that reason, chocolate melts easily in hot weather. You might think the advertisement from Cambridge University is funny, but if there is really a “doctor of chocolate”, he or she will help people a lot.
_________
One logo (商标) isn’t too expensive to print because it doesn’t need much ink, but printing a large number of logos could cost a lot. In order to save money and energy, an American design company made small changes to some famous brands, such as Nike, McDonald’s and Starbucks, to cut the cost. The design company remained the main body of these logos, but left an empty space inside. The logos look almost the same, but in this way, the famous brands could save 39 percent of the ink during the printing. Let’s hope other companies will take this advice. The way will save them money and use less energy, too.

【推荐1】In different countries, people have different manners. Some good manners in one country may be regarded as bad manners in another country.
If you go to Mongolia for the first time and some local people invite you to eat with them, you are supposed to give a loud “burp”(打嗝) after you finish eating. Burping at table shows you enjoy the food in Mongolia. However, in some other countries, it is quite impolite to give a loud “burp” at table.
In many countries people like to eat together with their friends. But in some parts of Polynesia, people think it is bad manners to be seen eating. They show their good manners by turning their backs on others while eating.
What are good manners in Eastern Africa? People think it is polite to pretend that they don’t see you when they are busy with their work. When you visit a friend in Eastern Africa, you should sit down beside him or her, waiting until he or she finishes his or her work. Then he or she will talk to you.
If you visit a friend in Saudi Arabia, you should walk behind the tents unless you get to your friend’s. If you pass in front of others’ tents, you will be invited to eat with them. And it is bad manners if you refuse the invitation.

【推荐2】Many people drive their cars to school or work now. So there are lots of cars on the streets. Sometimes, it’s not easy for you to get to school or work on time. Then you want to take a plane to school or work. Can your dream come true? Yes!
Four people in Germany (德国) make a new plane—Lilium Jet. It doesn’t look like a plane but an egg. Many people think it looks funny. The nice “egg” can take two people and “run” about three hundred kilometers an hour.
The Lilium Jet is not very big. So it doesn’t need an airport (机场). A small place is OK. Some people also call the Lilium Jet “a flying car”. It’s not difficult for you to learn to drive it. You can drive it like driving a car.
Maybe one day you can buy one if you like it. I’m sure your trip to school or work will be great.
