While Jennifer was at home taking an online exam for her business law class, a monitor（监控器）a few hundred miles away was watching her every move.

    Using a web camera equipped in Jennifer's Los Angeles apartment, the monitor in Phoenix tracked how frequently her eyes moved from the computer screen and listened for the secret sounds of a possible helper in the room. Her Internet access was locked — remotely — to prevent Internet searches, and her typing style was analyzed to make sure she was who she said she was: Did she enter her student number at the same speed as she had in the past? Or was she slowing down?

    In the battle against cheating, this is the cutting edge and a key to encouraging honesty in the booming field of online education. The technology gives trust to the entire system, to the institution and to online education in general. Only with solid measures against cheating, experts say, can Internet universities show that their exams and diplomas are valid — that students haven't just searched the Internet to get the right answers.

    Although online classes have existed for more than a decade, the concern over cheating has become sharper in the last year with the growth of “open online courses”. Private colleges, public universities and corporations are jumping into the online education field, spending millions of dollars to attract potential students, while also taking steps to help guarantee honesty at a distance.

    Aside from the web cameras, a number of other high-tech methods are becoming increasingly popular. Among them are programs that check students' identities using personal information, such as the telephone number they once used.

    Jack Ma, the founder and executive chairman of e-commerce giant Alibaba Group, and US president-elect Donald Trump met at Trump Tower in New York City on Jan,9th 2017, with Trump calling it a "great meeting" and Ma saying the meeting was "very productive"

    "We had a great meeting, and a great, great entrepreneur（企业家）, one of the best in the world, and he loves this country, and he loves China," Trump said. "Jack and I are going to do some great things."

    The two met with reporters briefly after the meeting, and said they discussed plans to create 1 million US jobs by allowing US small and medium-sized businesses to sell to China through Alibaba's platforms.

"We're focused on small business," Ma told reporters. And he had complimentary words for Trump: "I think the president-elect is very smart, he's very open-minded to listen. I told him my ideas about how to improve trade, especially to improve small business, cross-border trade."

    "We also think that the China and USA relationship should be strengthened — should be friendlier," Ma said. "The door is open for discussing the relationship and trade issues."

    The meeting comes in tensions between China and the incoming Trump administration(政府). Trump has repeatedly criticized China for its economic policies and accused the country of "stealing jobs away" from the US.

Trump also has said he may raise tariffs(关税) on Chinese goods sold in the US.

    Generations of children grew up reading comic(漫画) books secretly, hiding out from parents and teachers who saw them as a waste of time and a risk to young minds. Comics are now gaining a new respectability at school. That is thanks to an increasingly popular and creative programme, often aimed at struggling readers, that encourages children to plot, write and draw comic books, in many cases using themes from their own lives.

    The Comic Book Project was started in 2001 by Michael Bitz at an elementary school in Queens. Since its creation, the programme, which is mainly conducted after school, has spread to more than 850 schools across the country. It has gotten a big push from the craze(狂热) among adolescents for comic book clubs and for Manga, a widly popular variety of comic originating in Japan.

    The point is not to drop a comic book on a child's desk and say “read this”. Rather, the workshops give groups of students the opportunity to collaborate(合著) on often complex stories and charac-ters that they then revise, publish and share with others in their communities.

    Teachers are finding it easier to teach writing, grammar and punctuation with material that students are fully invested in(投入). And it turns out that comic books have other built-in advantages. The pairing of visual and written plotlines that they rely on appear to be especially helpful to struggling readers. No one is suggesting that comic books should substitute for traditional books or for standard reading and composition lessons. Teachers who would once have dismissed comics out of hand are learning to exploit(利用) a style that clearly has a powerful hold on young minds. They are using what works.

    Robots and humans will soon be living in harmony(和睦).A singing robot is being taught to create jazz with a human in a project.

    Antonio Chella from Italy is working with a Telenoid robot. To start with, the Telenoid will be trained to follow the movements and simple sounds made by a human singer, and to connect music with different emotional states. Chella then plans to see if the robot can use these connections to create music.

    Intelligence is often regarded as the ability to find connections between the existing things. But Chella suggests that a conscious(有意识的) creature should be able to go a step further and introduce new connections that result in the creation of something new.

    Some jazz musicians say that they should have a mental library of musical phrases so that they are able to combine them in new ways. More importantly, however, this combination happens in a state that is similar in a sense to dreaming. Chella wants to copy these states in a machine.

    “This work raises interesting questions about the link between consciousness and music making,” says Philippe Pasquier, a musician and computer scientist. But he is skeptical about whether a robot musician needs a physical body.

    Pasquier argues that the robots are faced with two challenges(挑战). Software that can copy Bach has already been developed. But interpretation（演绎）includes human's different tastes and judgments. “What made the Beatles famous was not so much their works, but the fact that the interpretations of the works were wonderful,” he says.

    It is not yet clear how a robot would go about interpreting music in a new way. But by copying humans and then learning to sing, Chella's robot could provide clues.

    What seems to be important is that human composers often listen to lots of music made by others. So Chella's robot had better listen to those jazz standards first.

    Whether you use a GPS device (设备) in your car or Google Maps on your smartphone, few of us travel anymore without digital help. {#blank#}1{#/blank#} For one thing, GPS isn't as accurate as you might think. What's more, science is beginning to discover that people who rely only on navigational technologies may have a poor sense of place during travel.

    {#blank#}2{#/blank#} They soon become outdated as cities change, requiring users to continually purchase updated versions. They're also easily damaged from exposure to water, poor weather conditions and other physical forces.

    However, paper maps still offer a few advantages that technologies can't. For example, studying a map allows you to get a full view of where you're going, including the roads, forests, towns, historic sites, rivers and mountains you'll come across along the way. Many older maps are wonderful, offering a lovely feast for the eyes. {#blank#}3{#/blank#}

    Research by Toru Ishikawa and colleagues at the University of Tokyo found that GPS users spent 30％ more time looking at their device than those who used a paper map. {#blank#}4{#/blank#} Instead they tended to stare at their screens and follow directions, never gaining a full view of where they were going.

    Therefore, go ahead and use your GPS, but also carry a paper map as a handy backup. {#blank#}5{#/blank#} Also it could even be a life-saver!
