1 . If your friend says she feels relaxed, but you see that she closes her hands into fists, you may doubt her words. Robots, however, might believe her. Body language says a lot, but robots have great difficulty in observing tiny body movements and can miss important social signals as a result.
Researchers at Carnegie Mellon University developed a body-tracking system that might help solve this problem. The system called OpenPose can track body movement in real time. One important quality of the OpenPose system is that it can track not only a person's head, body, arms and legs but also his fingers. To do that, the researchers used a dome （圆顶状物）lined with 500 cameras, where they recorded body movements at different angles and then used those pictures to build a data set.
They then passed those pictures through a keypoint detector to identify and label specific body parts. The software also learns to connect the body parts with different people, so it knows, for example, that a particular person's hand will always be close to his or her upper arm. This makes it possible to track multiple people at once.
The pictures from the dome were recorded in 2D. But the researchers used 3D technology to help the system understand how each movement appears from different angles. With all of this data processed, the system can determine how the whole hand looks even if some fingers cannot be seen.
Now that the system has this data set to draw from, it can run with just one camera and one computer. It no longer requires the camera-lined dome to determine body poses, making the technology mobile and accessible.
The researchers say this technology could be used for interactions between humans and machines. It could play a huge role in VR （虚拟现实）experiences, allowing finer detection of the user's physical movement without any added hardware. It could also help with more natural interactions with a home robot. You could tell your robot to “pick that up"， and it could easily understand what you're pointing at. By interpreting your physical gestures, the robot may even learn to read emotions by tracking body language. So when you' re silently crying with your face in your hands because a robot has taken your job, it might offer you a tissue.

2 . Immersive Van Gogh
From the creators of the blockbuster show in Paris seen by over two million visitors and still wowing crowds in Toronto, the west coast premiere (首场) of the Immersive Van Gogh Exhibit will bring the art of Vincent to life in Los Angeles.
Immersive art is not just a technical way to represent video and audio in huge spaces. The word immersive indicates a deep commitment of intentions which connect images and sounds in a way that the audience is able to experience a different way of the art.
True to its name, this exhibition transforms the iconic (偶像的) paintings of Vincent van Gogh into moving, wall-filling projections. “Immersive Van Gogh” promises half-a-million cubic feet of projections that pull from some of the post-impressionist’s most recognizable pieces, including The Bedroom, Sunflowers and, yes, The Starry Night.
You will experience art like never before—lose yourself in entrancing, moving images that highlight brushstrokes, detail, and color—truly illuminating (照亮) the mind of the genius.

3 . Twenty-five years ago, most young Britons wanted a career in law, to be a doctor, or, if they were creatively minded, to take up singing. But today, things stand differently.
According to a survey by Tesco Mobile, a UK telecoms company, the “dream job” of young people aged between 16 and 25 in the UK is a video blogger, or “vlogger”. The survey, carried out among 1 , 002 people, found that as much as 40 percent of them put vlogger as their number one choice on a list of ideal jobs.
The only reason for this change is undoubtedly the Internet and social media. They have made it so much easier to reach a global user, without having to get a job in show business in the traditional way.
“In years gone by, the biggest stars were shaped and trained by the Hollywood studios； now, anyone with a computer camera can become an icon (偶像)，" a Tesco Mobile spokesperson said in a news release(发布会).“These self-made stars record their hobbies to an admiring fan-base. Vloggers are the big stars of today because they are normal people interacting with their fans about everyday life.”
However, what people see is only the great side of being a vlogger and they ignore the fact that only those who are successful get fame and fortune. There are the dreams that come true and the dreams that still remain dreams.
This is why although vloggers are popular, some young people choose jobs that don't necessarily earn them fame, but allow them to make good use of the Internet to share their hobbies. Young Israeli David Leshaw, for example, runs a business called the Finishers Club. It's an online platform(平台)for runners to keep a record of their races. He told the website Zippia that his job allows him to express his thought, and is always a learning experience. And that's enough for him.
1. What's the most popular job among British young people nowadays?| A．A lawyer. | B．A doctor. | C．A vlogger. | D．A singer. |
| A．Because of the popularity of the computers. |
| B．Because the traditional show business has disappeared. |
| C．Because there are computer cameras for everyone to use. |
| D．Because Internet and social media made it easy to reach a global user. |
| A．To discuss. | B．To force. |
| C．To communicate. | D．To take part in. |
| A．All vloggers can't be successful. | B．Vloggers should be supported. |
| C．Vloggers should be encouraged. | D．Vloggers are very helpful to society. |

5 . The traditional Chinese lunar calendar(农历）divides the year into 24 solar terms(节气）．Start of Winter, the 19th solar term of the year,begins this year on Nov 7 and ends on Nov 21.
Start of Winter is the first solar term of winter,which means winter is coming and crops harvested in autumn should he stored up.
In ancient times, the Start of Winter was regarded as the beginning of winter, however,due to geographical factors, the actual winter time varies from place to place.
In fact,the Start of Winter is not the beginning of winter in terms of meteorology(气象学）。The weather every year is different, so the beginning of winter could be quite different.And as China is very large, it starts at different times in different areas.
The beginnings of the four seasons were important festivals in ancient times. Before the Start of Winter,the ancient emperor would take a shower and have no more meat.On that day,the emperor would lead his officials to the countryside and"welcome the winter".
People eat dumplings on the beginning of winter. Legend has it that in the late Eastern Han Dynasty,Zhang Zhongjing invented "Jiao Ear"(娇耳）to treat typhoid(伤寒） patients with ear frostbite(冻疮）.He cooked mutton,hot peppers and herbs to drive out the cold and warm up the body.He put these materials into a dough skin and made them into an ear shape.Since then,people have learned to make the food which became known as "dumpling" or jiaozi. Today there is still a saying that goes "Eat dumplings on Start of Winter Day, or your ears will be frostbitten.”

6 . Recently whenever I turned on my computer or my mobile phone, news about the great effect of Hurricane Harvey（哈维飓风）on thousands of people caught my eye. I saw many unfortunate events. However, there was also lots of bright news that showed the goodness of mankind. As a reporter, I reported many human-interest stories when doing my job, That’s why the story about the guys in the bakery（面包店）caught my eye.
When the workers at a Mexican bakery chain in Houston were trapped inside the building for two days, they didn't sit there feeling sorry for themselves. They used their time wisely after flooding caused by Hurricane Harvey. While waiting for the eventual rescue that came on Monday morning, the four workers decided to make as many loaves of bread as possible for people around the neighborhood. They talked to their manager about their plan over the phone and the manager agreed.
The flood water rose in the street outside. They took advantage of their emergency power supply to bake bread. They used more than 4,200 pounds of flour（面粉）to create hundreds of loaves and sheets of sweet bread. Although the water kept rising, they continued baking to help more people. By the time the manager managed to get to them, they had made so much bread that they took the loaves to lots of emergency centers across the city for people affected by the floods.
The store manager, Brian Alvarado, told The Independent, “They've done more than they should have done. And what they had done has lit a light for people. I feel lucky to have them work in the bakery.”
Whenever a disaster occurs, nobody should feelforlorn. Instead, we should stay hopeful and take positive action to save ourselves and help others. Our acts of kindness will make a big difference to the people in the world as well as the world itself.

8 . China will have the most 5G connections of any nation by 2025, according to a new study, while Europe will fall behind Korea, the United States and Japan in terms of 5G penetration(渗透)by that year.
5G is the fifth generation of network technology. It is expected to bring unbelievable speeds to Internet users, with some operations running 10 times faster than on 4G networks. 5G is also expected to unlock the potential in a lot of new services, including artificial intelligence, science of robots self-driving cars, and the Internet of things.
The GSMA said that China's three major mobile operators-China Unicorn, China Mobile, and China Telecom-are already moving ahead with 5G networks. While most nations will have 5G by updating existing foundations, the study noted that China plans to build part of its 5G networks.
One of the most distinguishing(显著的) factors between Chinese mobile operators and those in the rest of the world is the intention to erect the new and independent 5G networks. That is, China is determined to build a completely advanced 5G. The high cost underlines China's seriousness about paying whatever it takes.
Korea will lead the world in terms of 5G penetration in 2025, when 66 percent of the nation's total connections will be 5G, according to GSMA. This compares to 50 percent in the US, 49 percent in Japan, 36 percent in China, 30 percent in Europe, and a global average of 18 percent. Out of the five economies leading on 5G, Europe will have the lowest participation in 2025, as the area is moving more slowly in having its 5G networks.
1. What will 5G bring?| A．A completely new pattern for daily life. |
| B．Excellent networks and national safety. |
| C．Amazing speeds for public transportation. |
| D．Realizing the potential in many new services. |
| A．It will develop rapidly. | B．It may be lack of government support. |
| C．It will move forward slowly. | D．It may fall behind Europe. |
| A．bring up. | B．set up. | C．turn up. | D．pick up. |
| A．More than half Koreans use 5G in 2025. | B．Chinese cannot own 5G in 2025. |
| C．Only five countries will have 5G in 2025. | D．Europe will pay little attention to 5G in 2025. |
9 . Vegetarianism (素食主义) is growing in popularity in lot of countries. And now, South Africa is one of them. Today, more and more South Africans are experimenting with the vegetarian way of life by cutting all meat out of their diet.
Others are exploring veganism (纯素食主义). Vegans are similar to vegetarians but they avoid all animal-based products, including milk and eggs. Some vegans do not eat honey. There is no official count of how many vegans there are in South Africa. But the interest has led to the birth of vegetarian and vegan restaurants in Johannesbur, the nation’s economic center. And this year. Africa’s first big vegan and plant-based- festival launches in Cape Town. The Vegan & Plant Powered Show takes place at the end of May.
But veganism can be lonely road for many South Africans. The country is Africa’s top consumer of meat from cows, pigs and sheep, based on information from the Organisation for Economic Co-operation and Development. Many South Africans express shock at the thought of giving up meat, which is central to celebrations and spirituality.
This is an issue for many African vegans, including Anesu Mbizvo. “In African culture, a big part of family’s net worth is their livestock (畜牧). Their livestock define the wealth of family. And so when you kill an animal at a gathering, it’s seen as you giving of yourself.” But offering home-grown vegetables, she added, would not be considered as valuable. She said, “I think that’s one of the barriers to veganism for people of African cultures.”
Some South Africans are finding their path somewhere in the middle. Thirty-one-year-old Thandiwe Ngubeni is a communications specialist. She still eats meat—but less and less of it as time goes by. “I feel more energetic when I eat a vegetarian or vegan meal. It actually just gives me more energy.”
1. Which of the following best describes vegans?| A．They eat a little meat. |
| B．They only eat vegetables. |
| C．They build vegan restaurants. |
| D．They refuse any food from animals. |
| A．A huge demand for meat. |
| B．Traditional views of livestock. |
| C．Ignoring the value of vegetables. |
| D．Gap between the rich and the poor. |
| A．She is a vegan. | B．She is a vegetarian. |
| C．She takes the middle road. | D．She refuses to eat any meat. |
| A．Many South Africans Welcome a Vegan Lifestyle |
| B．Meat in South Africa Will Become Less Valuable |
| C．Veganism Is impossible to Practice in South Africa |
| D．Vegans’ Behaviors Are Too Extreme |
10 . Sorry to say, our brains naturally start slowing down at the cruelly young age of 30. It used to be thought that this couldn’t be helped, but people of any age could train their brains to be faster and, in effect, younger. Your brain is a learning machine. Given the right tools, we can train our brains to act like they did when we were younger. All that’s required is dedicated (专注的) practice: exercises for the mind.
A scientist has developed a computer—based training schedule to speed up how the brain processes information, Brain HQ. Since much of the data we receive comes through speech, the Brain Fitness Program works with language and hearing to improve both speed and accuracy. Over the course of your training, the program starts asking you to distinguish sounds (between “dog” and “bog”, for instance) at an increasingly faster rate. It’s a bit like a tennis instructor, shooting balls at you faster and faster over the course of the summer to keep you challenged. Though you may have started out slow, a month later you’re pretty quick.
The biggest finding in brain research in the last ten years is that the brain at any age is highly adaptable. If you ask your brain to learn it will learn. And it may speed up in the process. To keep your brain young, you can do one of a million new activities that challenge and excite you: playing Ping-Pong or contract bridge, doing puzzles, learning new language or a dance, taking piano lessons, building model airplane mastering gardening technique, discovering the secrets of beer-making and, sure, relearning advanced mathematics. Anything that closely engages your focus and is strongly rewarding will kick your brain into learning mode and will definitely improve it.
