Schools in China are studying how they can put VR (=virtual reality虚拟现实) lessons into their classroom experience. One such lesson uses VR to teach children fire safety. Instead of pens and paper, students wear VR headsets in the classroom. They are put into a virtual environment where a fire has broken out. They must find their way out and escape carefully.
At the VR medical school under Sichuan University, a virtual system allows medical students to examine human body in different ways. They can even separate the body for closer examination. Students can practice their operation skills without a real body.
Simon Leung, vice-chairman of a VR company, said the company has developed VR classrooms and computers that send students to a 360 degree digital world. Moreover, the VR headsets can tell whether children are focused on the task at hand, Leung said.
Chinese parents, however, have a different opinion on VR lessons. They are suspicious of VR because they are unsure if the technology will have any bad effects. They are worried about their children’s eye sight, too.
Besides, VR equipment comes at a high price. A top VR headset and computer could cost up to 10,000 yuan(1,475 U. S. dollars). “We need to do more to lower the cost and improve the user’s experience,” said Huang Ronghuai, professor at the Smart Learning Institute under Beijing Normal University, “But we are sure that we will change the model of education in the future.”

① Do you ever worry about math when you’re at school? One important thing is to sit up straight when you’re taking your math exams, according to the scientists. Good posture (姿势) can help people feel more positive and careful. Sportsmen, musicians and public speakers can all get advantages from good posture. | ② We all know air pollution is bad for our health. But it can also harm us in other ways. Scientists have found that air pollution may lead to more crimes. According to a study of 86 million people in the US, the worse the air pollution was, the more violent crime (暴力犯罪) there was. Scientists think the small pieces and toxic gas (毒气) in air may affect people’s actions. This might make them more violent. |
③ Can AI read our minds? This might not be far away. Scientists from Australia and Germany have developed a type of AI that can guess people’s feelings by tracking (跟踪) and studying their eye movements. This finding could make robots and computers better at understanding humans. | ④ Believe it or not, sportsmen tend to have worse teeth. A study shows that half of the top athletes (运动员) have tooth problems. This seems strange. They usually pay more attention to their health than the rest of us.

Robots are supposed to run on batteries, right? Well not all of them.
Scientists in England have built a kind of small robots that get their energy from dead flies, bad apples, or sugar.
One robot, called Slugbot, was even designed to hunt(猎取) garden slugs for dinner!
What’s up with all that food?
Well, scientists at the Bristol Robotics Laboratory want to invent robots that can operate for a long time in dark, dirty, or dangerous places.
Many of those spots, like the seafloor or Antarctica, don’t have electrical sockets(插座).
So inventor Chris Melhuish came up with a better idea: Build robots that get their energy just like animals do by hunting and eating food from their environment.
One robot, called Ecobot Ⅱ, could run for 12 days on a diet of eight flies! Of course, it’d still get a lot more power from one AA battery, though.
Melhuish says his team is now working on a new and improved robot, called Ecobot III, which will have a better digestion system.
It seems that after an eight-fly dinner, Ecobot II couldn’t deal with the leftover(剩下的) “waste”.
Maybe restrooms in the future will have signs for boys, girls, and robots.

【推荐3】Today there are more than 7 billion people on the earth. By the year 2050 there may be 12.5 billion. There are a lot of people to feed. We need more and more food.
One way to produce more food is growing stronger plants. For thousands of years, farmers have made plants better. Every season, they pick the best plants for the next season. It works very slowly. Since 1983, scientists have been able to change plants more quickly by changing their genetic (基因的) material. Foods from plants grown in this way are called genetically modified(转基因的) foods, or GM foods.
By changing the genetic material of a plant, it is possible to make new plants. They make plants which are strong against plant diseases. They can also help in our diseases. A kind of rice is being prepared, for example, which stops children becoming blind.
Rich countries produce GM foods because they are easy to grow and bring in more money. Poor countries are interested in them because they help produce more food.
GM plants are not natural. No one knows how good or bad they are. Making GM foods is only one way of feeding people in 2050. There are strong feelings against them, because they are unnatural. They may feed people, then hurt them or their children later. But both rich and poor countries are interested in their use, and they are not going to go away. In 2050, we may think differently about them.

【推荐1】Last year, China introduced the “double reduction(双减)” policy in order to reduce students’ learning burden(负担) by reducing homework and after-school classes.
“Our homework is clearly less than before,” said 13-year-old Shen Yuzhe from Beijing. “
According to her, teachers now teach at a much slower pace(节奏).
For 13-year-old Zhang Hangming from Tianjin, the best thing about “double reduction” is the increased time in after-school activities. “
Both Shen and Zhang find there are fewer exams now.
Shen also pointed out that when burden is lightened, self-discipline(自律) becomes the key. “Some students now spend more time having fun when homework is finished early. But if you use all the free time to relax, you might fall behind your peers(同龄人),” he said.

【推荐2】Is it brave or embarrassing to speak in a language you’re not quite good at? That’s the question being asked in China after a famous businessman gave a short speech in English.
It was a pretty standard conversation: “Hello! How are you?” in our textbook. But the fact is that it was given in English by one of China’s most famous businessmen, Lei Jun, the founder and chief executive of the phone company Xiaomi, the world’s third-largest maker of smartphones. He made a speech in awkward English when he was in India for a new smartphone in April. Trying to interact（互动）with the audience, Lei announced that everyone would be given a free Xiaomi smart wristband（腕带）and asked, “Are you OK?” The phrase quickly became the object of ridicule（嘲笑）on social media. And it didn’t take long for his speech to be made into a rap song, repeating the phrase: “Are you OK?”
In fact, Lei’s English was more or less understandable, though his pronunciation is bad. Video of the event has been watched more than 450, 000 times on the Chinese site Youku. More than a thousand people wrote their ideas after watching. One of the comments（评论）is “His English is so bad that he shouldn’t have spoken in it at all.” But others argued that Lei was brave enough to speak English in India. “Even foreigners will try to be friendly with us by trying to speak in Chinese.”
English is taught as the second language in many Chinese schools, but some schools and students don’t pay enough attention to the pronunciation and can just speak like robots. Lei himself has written something on his Weibo page to express surprise at the online interest. “I went on stage and spoke several sentences in English only to make Indian Xiaomi fans excited. I have never thought video of the speech will spread to China so quickly. Everyone in China is laughing. Since there are more and more Xiaomi fans overseas, I really should improve my English so that I won’t let everyone down!” he wrote.

Are you sorry for not traveling during the National Day? If you stay at home at that time, I think you are very lucky. Why? Because there are too many people everywhere. In many places of interest in China, it's too crowded to do anything.
Look at the picture. It was too crowded in the West Lake on October 1st, 2020. You even couldn't take photos for you or your friends. All what we could see were people. It was reported that there were about 13 people per meter by the lake. My friends told me they could see nothing but many tourists on the Broken Bridge(断桥). "We couldn't walk if the people in front of us didn't walk," he said. He showed us a photo near the West Lake. In the photo, we hardly found him out, there were too many people.
So some people give the advice that we should not have the gold week any more. But other people say no about this advice. What's your idea of it? Are you sorry now for not traveling during the gold week? I love staying at home more than traveling next National Day.

【推荐2】Cardiac arrest (心脏骤停) happens when the heart suddenly and unexpectedly stops pumping blood. 90% of the people who have a cardiac arrest outside of a hospital die—often within minutes. That is because they do not receive treatment quickly enough to survive. Cardiac arrest is a common cause of death. It causes about 300,000 to 450,000 deaths in the United States each year.
If cardiac arrest happens, rapid treatment with a medical device called automated external defibrillator (AED) can be lifesaving. Many AEDs can be easily seen in public places, including offices, schools, shopping malls, grocery stores, and airports. An AED system includes an AED and its necessary accessories (配件), such as a battery and pad electrodes (片状电极). The AED gives verbal instructions to users, which means it gives voice instructions to tell users how to use it.
This is how an AED works. First, the user turns on the AED and follows the recorded voice instructions. Second, the user puts two electrodes on the chest of the person in cardiac arrest. Third, the electrodes send information about the person’s heart rhythm (心律) to the AED, and then it decides whether an electric shock (电击) is needed. Fourth, if a shock is needed, the AED tells the user when to press a button to give a shock. In some AEDs, the user doesn’t need to press any button. The AEDs will give a shock themself.
1. Why do so many people in cardiac arrest outside a hospital die?| A．Because 90% of them lose too much blood. | B．Because they can’t get treatment fast enough. |

【推荐3】Our school held many activities last week. We called it Road Safety Week. One of the educational activities was a speech (演讲) given by a police officer. He shared something about the road safety. Here are some important points about his opinions.
Most traffic accidents (事故) shouldn’t happen. They happen because people are careless. Some people drive too fast. This means that if they have to stop suddenly, they cannot stop quickly enough to avoid hitting (避免撞) others. You need to remember this when you are crossing the street or walking along the sidewalk (人行道) .
People on foot-pedestrians (行人), and bicycle riders often cause accidents, too. Pedestrians sometimes walk out into the street without looking. You should always look on both sides before stepping into the street.
Do any of you ride a bike? Bicycle riders can cause accidents by changing directions (方向) suddenly or without warning (警告) other road users. Before you turn left, for example, you should check behind you to make sure there aren’t any cars or buses coming. You should show with your left hand to tell that you want to turn left. You should not turn until the street is clear. The rules of the road are very simple. If we learn them and follow them, we should not have accidents any more. There were more other activities in Road Safety Week, hope every student could learn something.
