Electric vehicles have been around for more than a hundred years. But they have really been liked by a large number of people over the last ten years. More than three million all—electric cars, trucks and vans are now on the road worldwide.
Helping the Environment
Most cars run on gasoline. Burning gasoline and other fossil fuels produces greenhouse gases. Electric vehicles don’t burn gasoline. Instead, strong batteries run their electric engines. So, electric vehicles don’t directly produce greenhouse gases.
Poop Power!
Electric vehicles are better for the environment. But they are not perfect. Their batteries often use electricity that was made by burning fossil fuels. But an electric vehicle uses less energy than a vehicle that runs on gasoline. Plus, some of the electricity comes from “greener” sources, such as solar and wind power. And some may soon come from a new source — cow poop! An electric car company has worked together with a large dairy farm. They plan to make electricity using a greenhouse gas from cow poop.
Always Improving
One of the problems for electric vehicles is their limited range. This is how far they can travel before their batteries need another charge. But now their range is improving. Some new electric vehicles can travel almost three times as far as older ones did. Another problem is finding a place to recharge the batteries. But the number of charging stations is going up as well. China now has thousands more charging stations than it did ten years ago. In Sweden, engineers have even designed a road that will charge electric vehicles as they drive along.

【推荐1】ChatGPT, a smart AI chat-robot tool, has swept the education 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 the homework.
Developed by US company OpenAI, ChatGPT is a powerful tool. You can ask it to write stories and emails, create recipes, 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 stopped students and teachers from using ChatGPT on the district’s networks and devices.
The move comes out of worries that the tool could make it easier for students to cheat on homework. Some also worry that ChatGPT could be used to spread inaccurate (不确定的) information.
“It does not build critical-thinking (批判性思维) and problem-solving skills, which are necessary for academic (学术的) and lifelong success,” said Jenna Lyle, the deputy press secretary of the New York City Department of Education.
Apart from bans, teachers are making changes to their classes to block 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 educators say “no” to ChatGPT. Some Canadian universities are drafting (起草) policies on its use, for both students and teachers. They have no plans to completely ban the tool so far.
Bhaskar Vira, the headmaster at the University of Cambridge in the UK, said that bans on AI software like ChatGPT are not wise. “We have to know that AI is a tool people will use,” he told Varsity, the school newspaper of the university. What we need to do is “adapt (调整) our learning, teaching and examinations”. That way, we can “have integrity (诚信) while recognizing the use of the tool”.

【推荐2】Developed by US company OpenAI, ChatGPT has taken the internet by storm, winning 100 million users since it came out in November 2022. People can ask the robot to write stories and emails, create instructions for cooking a certain food, translate languages, and answer all kinds of questions. In its own words, it is “a language model trained in a large amount of internet text to help users get human-like text.”
Compared with Siri or other chatbots, ChatGPT uses a much bigger information center for training. It also uses stronger software (软件) and hardware to learn things by itself. For example, if it provides a wrong answer to your question, you can tell it the right one and it will correct itself. “It’s a totally different chatbot,” computer scientist Liu Xiaoguang from Nankai University told Tianjin Daily. “The knowledge level ChatGPT shows is the same as a university student. That’s why it shocked the world.”
But one big problem with ChatGPT is that it makes mistakes or even gives false information. When Rezza, a 28-year-old from Indonesia, used the robot to write an essay (论文), it “gave out many examples which other writers actually hadn’t mentioned at all”, he told The Guardian. Since the robot is trained using words from the internet, it can also pick up biases (偏见) about certain groups. These are all things that need to be dealt with.

【推荐3】The world’s largest amphibious(水陆两栖的) airplane, AG-600, carried out its first flight on December 24th, 2017 in Zhuhai, a city in Guangdong Province. It is a plane that can take off and land on both ground and water. AG-600 took off from Jinwan Airport at 9:39 am. The flight took about one hour before the airplane landed at the same airport.
AG-600 is one of three large airplanes made in China. The other two are Y-20 and C919.AG-600 can cover a maximum (最多的) flight distance of 4,500 kilometers and carry a maximum weight of 53.5 tons at a time. The development of it begin in March 2014 and was completed in July 2016. In April, the first ground test was successful. In early December, the airplane received the government’s approval (批准) for the first flight.
The airplane will mainly be used for firefighting and search and rescue(援救、营救) at sea. It can also be developed to do research on the environment and resource at sea. According to Huang Lingcai, one of its main designers, the airplane can make round trips without refueling (补充燃料)from the southern island province of Hainan. It is able to save 50 people when doing a rescue mission(使命) at sea. To put out forest fires, it can collect 12 tons of water from a nearby lake or sea in 20 seconds and then use the water to put out fires in an area of around 4,000 square meters. It is said that the airplane will be of great importance to the country’s emergency rescue system and the building of strong sea power.
Next, the airplane will continue to make flight tests and will be put into use after it is proved to be safe and useful enough.

【推荐1】Australia is the greatest island in the world. It is to the south of the equator (赤道). So when it is summer in our country, it is cold winter in Australia.
Australia is big, but the population there is small. The population is the same as that of Shanghai, a city of China. Australia is a young and diverse (多样化的) nation and Australian people come from many different countries.
Australia has many, many sheep. After a short drive from town, you will see sheep around you. You can also find kangaroo has a “bag” below its chest. The mother kangaroo keeps its baby in the “bag”.
Australia is considered to be a relaxing, informal society. When greeting others, students and young people say “Hello” or “Hi”. Sometimes they will say “How’s it going?” or “‘G’ day”. In more formal (正式的) situations they usually shake hands the first time they meet. “Good morning”, “Good afternoon” or “Pleased to meet you” are formal greetings. English is Australia’s national language.

【推荐3】Manners are very important for our daily life. There are many different customs and habits among different countries. We must fmd out and follow their customs so that they will not think us ill-mannered. Here are examples of the things that a person with good education should do.
If you visit a Chinese family, you should knock at the door first. When the door opens, you will not move before the host says “Come in, please.” After you enter the room, you would not sit down until the host asks you to take a seat. When a cup of tea is sent to your hand, you should say “Thank you” and receive it with two hands. Before entering a house in Japan, it is good manners to take off your shoes. In European countries, even though shoes sometimes become very dirty, this is not done. In a Malay house, a visitor always leaves a little food to show that he has had enough. In England, a visitor always finishes the food to show that he has enjoyed it. The host will be pleased with that.
You have to give your present in public in the Middle East to show it is not a bribe. But it’s good manners to give your present in private in Asia. You mustn’t give knives in Latin America because it suggests that you want to cut off the relationship. You mustn’t give your food to Arabia because it suggests that you think your host isn’t offering you enough to eat.
“Come any time” means “I want you to visit me” in India. If you don’t suggest a time at once, the India will think you are refusing the invitation. But if an Englishman says “Come any time”, they will think you are impolite if you start fixing a date.
