It raises a troubling question for all of us—when will a machine be able to do my job? Katja Grace, a research associate at the University of Oxford's Future of Humanity Institute, and her colleagues from the AI Impacts project and the Machine Intelligence Research Institute, have surveyed 352 scientists and compiled (汇集) their answers into predictions about how long it may take for machines to outperform humans on various tasks.

The good news is that many of us will probably be safe in our jobs for some time to come. The researchers predict there is a 50% chance that machines will be capable of taking over all human jobs in 120 years.

"One of the biggest surprises was the overall lateness of the predictions," says Grace. "I expected the amazing progress in machine learning in recent years, plus the fact that we were only talking to machine learning researchers, to make the estimates earlier."

"I am a bit sceptical of some of the timelines given for tasks that involve physical manipulation (操纵)," says Jeremy Wyatt, professor of robotics and artificial intelligence at the University of Birmingham. "It is one thing doing it in the lab, and quite another having a robot that can do a job reliably in the real world better than a human."

Manipulating physical objects in the real world—figuring out what to manipulate, and how, in a random, changing environment—is an incredibly complex job for a machine. Tasks that don't involve physical manipulation are easier to teach.

Perhaps the hardest jobs for machines to perform are those that take years of training for humans to excel at. These often involve intuitive (直觉的) decision making, complex physical environments or abstract thinking—all things computers struggle with.

[1] Inakadate is considered the home of Tanbo art, a rice field art form. Its story as a world-renowned tourist destination began in the early 1990s, when local authorities realized that youths were moving to large urban centers continuously, and started brainstorming for ways of reviving (焕发生机) the village. One of the proposed ideas was an art form inspired by the local's traditional rice farming, done by hand for hundreds of years. Tanbo art involved the use of different-color rice varieties to turn local rice fields into giant canvases (画布) for complicated designs that revealed their beauty when viewed from above.

[2] The first rice field artwork was unveiled in 1993, when purple and yellow rice plants were used to create a detailed picture of Mt. Iwaki — the highest mountain in Aomori — along with easily recognized characters. A viewing platform was set up somewhere above the rice field, from which people could admire the unique artwork in all its glory. The project was so successful that Inakadate authorities decided to turn it into a yearly event.

[3] To create the impressively massive rice field artworks, locals use a technique which involves surveying the rice fields, perspective drawing (透视绘图), and the handmade plantation of various types of rice plants to create the desired visual effect. Tanbo art has come a long way in the last three decades, with designs gradually becoming larger and more complicated.

[4] Many locals say that Tanbo art has saved Inakadate, bringing in impressive numbers of people from all over the world and boosting the local economy. According to CoolJP, around 200,000 people flocked to Inakadate to see its unique artworks in 2006, and by 2016 that number had ballooned to around 340,000.

When was the last time you went to an interview? How did it go? There are lots of things to remember and prepare. However, one important thing to think about is your body language as it can really help you get the job. With a good understanding of body language in interviews, you can communicate the right messages, and even understand what the interviewer is saying or thinking. Here are some really useful things you need to know about body language in interviews.

Greetings

When greeting the interviewer, smile, look him in the eye and introduce yourself in a strong and confident voice. Also, remember that in most English-speaking countries (the UK, the USA, Australia, Canada, etc.), a firm handshake is seen as a sign of trust; and a limp handshake could make you appear weak or disinterested. Experts recommend waiting for the interviewer to extend his hand first.

Palms (手掌)

When possible, keep your palms facing up to show that you're open, trustworthy and interested. Research has shown that if we can't see the other person's open palms, we subconsciously become suspicious of them.

Mirroring

Mirroring involves copying what someone does with their body. For example, if the interviewer places a hand on their leg, you should do the same, but not too obviously. Experts have shown that mirroring someone can make him like you, or even think that you're more honest and trustworthy. However, be careful—if the other person knows about this technique, he might notice you doing it.

Sitting position

When sitting, if you lean back, you could appear lazy or arrogant; and if you lean forward too much, you might appear aggressive. The ideal posture is to sit with your back straight and your shoulders back a bit, leaning in very slightly. Sit with your legs slightly apart to give the impression of self-confidence and try to angle your knees and feet so they're pointing towards the interviewer.

One of the most endangered animals in the world is the Siberian tiger, (know) as the Northeast Tiger in China. There are less than 500 of these beautiful animals still living in the wild. The Siberian tiger is the largest of all tigers. adult male can grow up to 3.3 meters in (long) and weigh as much as 300 kilograms.

Long ago, Siberian tigers were all over Northeast Asia and Russian Far East., today they are found mainly along the Chinese-Russian border and (possible) in North Korea. The main reason for their decrease in numbers is the disappearance of their natural habitat. Fortunately, steps (take) to save this magnificent creature in recent years and as a consequence numbers are the rise.

There is also a fairly large population of Siberian tigers in zoos, some of are expected to be reintroduced to the wild. Of course, they would need to learn how to hunt and take care of (they), and this is easier said than done. Another big issue is the problem of space. At present, there just is not enough (spoil) forest available to support reintroducing many Siberian tigers into the wild.

My mother believed in using things up. Last year, our cornfield had a bad harvest because birds feasted on the crops. It was probably then that Mom's frugality(节俭)became even more extraordinary. She began keeping everything that seemed useless in the attic(阁楼)—worn-out clothes, old sheets, broken umbrellas, and some other old items. Mom's favorite saying was "waste not, want not"(俭以防匮). My brother Josh and I weren't sure what that meant until the "Affair of the Scarecrow(稻草人)", which, as it later became known, left a lasting impression on us.

The story began with a pretty hat that Mom received as a gift to protect her from the sun. However, Josh and I could see that Mom's frugal nature and fashion sense were in battle. Mom really didn't want to get rid of the hat—it was new and had a lot of use left in it—but neither could she stand wearing it. She tried to take off the fancy decorations, but they were stuck on tight. She'd have to find some other solution.

Josh and I watched as Mom headed upstairs to the attic with the hat. "Waste not, want not," she called back down. We heard boxes being moved around. Moments later, Mom leaned out, holding a flour bag full of straw, and with a mysterious smile, she placed the hat on it.

"What is that for?" I asked, confused. "A scarecrow! " Mom exclaimed. "But not a good one yet.It needs a strong body to stand firm in the field," she said with a frown. "And it doesn't look scary enough," Josh remarked. I had to admit that Josh, though younger than I was, could sometimes be more imaginative. Josh and I turned to each other, searching for a good idea. Soon enough, Josh's eyes lit up with inspiration.

Chopsticks, or kuaizi in Chinese, are a pair of small equal-length sticks, usually made of wood, used for eating. We Chinese eatchopsticks. It is believed the first chopsticks(develop) over 5,000 years ago in China. Excavated (出土) from the Ruins of Yin near Anyang, Henan province, dating back to roughly 1,200 BC was the(early) evidence of a pair of chopsticks made out of bronze. Chopsticks,are roughly uniform in size throughout China, can be made of a variety of(material), including bamboo, wood, plastic, silver and gold.

Chopsticks playimportant role in Chinese food culture. Chinese chopsticks are usually 9 to 10 inches long. They are round on the eating end which symbolizes heaven, and the other end is square which symbolizes earth. This is because(maintain) an enough food supply is the greatest concern between heaven and earth.

There is an old Chinese custom making chopsticks part, of a girl's dowry (嫁妆) since the(pronounce) of kuaizi is similar to the words for "quick" and "son".

Chopsticks are(frequent) used in daily life. They have become more than a kind of tableware and have established a set of etiquette (礼仪) and customs of(they) own.

My principal (校长) pushed her head into my classroom and said, "Friendly2! You need to make sure your word wall is3 by tomorrow morning." She then moved on to the next classroom to4 the message. I sighed and thought, "Are you making a(n)5? What a waste of my time!"

My principal was6 about making our school beautiful, while my goal was to get my students to pass the Algebra Regents Exam. She wanted every classroom to have a word wall, where student's works on creative projects would be7. She brought in beautiful planters (花盆) that8 the hallways with greenery. However, I assume that school and classroom9 aren't important when it comes to learning. To me, spending time and money making our school and classrooms beautiful was just a distraction (使人分心的事). Those things don't10 my students with math.

However, after three years of teaching, I went to graduate school in part to study how resources11 teachers and students. What my research found12 me: When teachers13 their classroom environment resources, their students did better on standardized tests. My principal was14. She was creating more than just a beautiful15—she was building a welcoming and positive environment for students to learn and teachers to work.

First of all, be sure to choose accessible books. Authoritative reading lists are a great guideline for the books you select for your kids. A quick way to assess whether or not a book suits your child is to have them read a page from it. If he or she comes across 2-3 unfamiliar words, that book in general should be at his or her level. This doesn't mean more challenging books should be thrown aside completely. These books provide a great opportunity for group reading and discussion with a parent.

Another way is to let your kids have a say in what they want to read. Have them select books based on his or her interest and books they find enjoyable. Such fun books as Captain Underpants, comics, and even the Guinness Book of World Records suit kids' taste and serve the purpose.

Finally, create settings where reading is a natural part of their positive memories. Read while lying on the beach, or snuggle up with family and a beloved book. When associating reading with the happy memories, kids will be much more willing to read at their leisure as they grow older.

A. There are endless means of doing this.

B. To improve their reading skills is essential.

C. Books with top-level difficulty are unavailable.

D. Reading is a fantastic way to relax and reduce stress.

E. The benefits of reading are beyond question even in the digital age.

F. Even so, you'd better single out books appropriate to their reading levels.

G. The joint reading sessions are invaluable for your child's growth as a reader.

Researchers at Binghamton University are working on a biometric (生物特征的) system that records how your brain reacts to certain images. With a little more polishing, the scientists' brainchild could become the way you get into a safe deposit box, your office or past scanners at the airport. It could replace the password for your online banking, your e-mail or your social media accounts.

They started their project by measuring the brain waves of 30 subjects. The subjects were fitted with a cap that had 30 electrodes attached to it, and then shown various images and symbols — celebrity faces, words, pictures of food — on a computer screen in 200-millisecond bursts. The brain's reaction was recorded.

The idea is that every time a person needs to use a "password", he or she goes through the same procedure, and the results are matched to their first-time reaction. If the "brainprint" is cracked — like what happened to the fingerprint records — then the system is merely reset by running another set of images and collecting a different set of brain waves."Even if that was stolen, you could just cancel it and record one to something else", says professor Laszlo.

Laszlo and her team have shown that their system can be 100 per cent accurate. So one of the most difficult parts of making the system practical already has been overcome. Now, they're spending much time recording accurate brainprints with as few as three electrodes, which could make recording in the future as easy as wearing a pair of special glasses. They're also working with cheaper materials and different methods to see if they can bring the cost down.

Over a year ago, work to develop automaton (自动化) began. At first, it was designed like a machine, and didn't live up to expectations. Then the company sought ways to improve it. In the end, it was given two arms with joints to copy wrists and elbows, allowing it to move a stick similarly to how a human conductor would move it. It was named the EverR 6 robot, and stands at 1.8 meters. It was finally time to figure out how it could follow through on its musical role.

"We got involved in this project to see how far robots can go in more creative fields like the arts, and what the challenges are," Dong-wook Lee, a senior researcher at the Korean Institute of Industrial Technology said.

In order to pull this off, Dong-wook Lee cooperated with the Busan Philharmonic Orchestra. The 12-minute piece they planned to perform, "Feel" by Il-hoon Son, was created specifically for this event. It was created with the strengths of both EverR 6 and the human conductor, Soo-yeol Choi, in mind.

To pull off this impressive performance, the robot was preprogrammed to conduct through 30 cycles of beat patterns. Meanwhile, it was up to the human conductor to lead the orchestra in creating an improvisational (即兴的) score, adding depth to the otherwise planned piece.

Together, they pulled off a masterful performance that the audience seemed more than happy to have had the opportunity to witness it firsthand!

With the concert having gone so well, this is only the start of EverR 6. Still, no matter the improvements they're able to make to this Android robot, the human conductor isn't concerned about being replaced.

"Let's leave the accuracy to the robots," Soo-yeol Choi said, "but the musical and artistic aspects to a human conductor."

I always wanted to know what my mom was reading. Hearing mom say, "I can't believe what's printed in the newspaper this morning," made me want to grab it out of her hands and read it myself. I wanted to be like my mom and know all of the things she knew. So I carried around a book, and each night, just to be like her, I would pretend to be reading.

This is how everyone learned to read. We would start off with sentences, then paragraphs, and then stories. It seemed an unending journey, but even as a six-year-old girl I realized that knowing how to read could open many doors. When mom said, "The C-A-N-D-Y is hidden on the top shelf," I knew where the candy was. My progress in reading raised my curiosity, and I wanted to know everything. I often found myself telling my mom to drive more slowly, so that I could read all of the road signs we passed.

Most of my reading through primary, middle and high school was factual reading. I read for knowledge, and to make A's on my tests. Occasionally, I would read a novel that was assigned, but I didn't enjoy this type of reading. I liked facts, things that are concrete. I thought anything abstract left too much room for argument.

Yet, now that I'm growing and the world I once knew as being so simple is becoming more complex, I find myself needing away to escape. By opening a novel, I can leave behind my burdens and enter into a wonderful and mysterious world where I am now a new character. In these worlds I can become anyone. I don't have to write down what happened or what technique the author was using when he or she wrote this. I just read to relax.

We're taught to read because it's necessary for much of human understanding. Reading is a vital part of my life. Reading satisfies my desire to keep learning. And I've found that the possibilities that lie within books are limitless.

E-Scooters

Over the past two years, electric scooters have become ever-present in many of Europe and America's biggest cities. Britain is the last major western European country to hold out against the . E-scooters are not allowed on public roads, though people do ride them on cycle  and pavements. But where they are permitted, the number of e-scooter sharing companies soars . To their , e-scooters are revolutionary: the "iPhone Of urban transport". To their critics (批评者), they are dangerous, anti-social and very annoying.

As with a dockless (无桩) bike, scooters are fitted with GPS trackers and wireless . Customers download an app and scan a QR code on the scooter to unlock it. They are then  a small amount. Bird, which launched its e-scooter in Santa Monica, California in September 2017 charges $l plus 15 cents per minute, on average, in the US-to travel where they want to go, at a maximum speed of around 15mph. At night, the scooters are rounded up, charged and returned to popularity.

E-Scooters have the potential to solve some of the worlds biggest transport problems. Most cities are already dangerously polluted and heavily congested, and it is simply not an option to put more cars and taxis on the streets. Scooters are efficient; one kilowatt hour of energy carries a car  by petrol less than a mile, and an e-scooter 80 miles.

Scooters are clean, cheap, and they require little new infrastructure. For a country like car- America, they could genuinely transform an  60% of US journeys under six miles. Even in European cities, which  have good public transport systems, they are very useful for travelling the "final mile". According to Bird,40% of taxi-riding journeys in London are under two miles, so e-scooters could help take a lot of cars off the streets.
