4 . Cities are difficult to navigate (导航) at the best of times, but for people with disabilities they can be like courses with hurdles and bring inconvenience to disabled people.
A UK national travel survey found that adults with mobility difficulties took 39% fewer trips than those with no disability in 2017. Yet that could change as devices and cities grow smarter. Assistive tech is playing a big role in the transformation. The global value of the industry is expected to increase from $14 billion in 2015 to $30.8 billion in 2024, according to Zion Market Research.
One of the things that could transform lives is a smart walking stick designed by engineers from Young Guru Academy (YGA) in Turkey. The WeWalk stick has a sensor that detects hurdles above chest level and uses vibrations (振动) to warn the user. It can be paired with a smartphone to help navigation, and is connected with a voice assistant and Google Maps.
Ceylan, who has been blind since birth, says that connecting the stick to the Internet of Things and smart city solutions makes it user-friendly. “As a blind person, when I am at the Metro station I don’t know which is my exit ... I don’t know which bus is approaching ... which stores are around me. That kind of information can be provided with the WeWalk,” he says.
“The smart walking stick is really an exciting initiative that will make a huge difference to some people,” says Anna Lawson, the director of the Center for Disability Studies at Leeds University in the United Kingdom. “But they are very expensive ... they’re not going to be available to the vast majority of disabled people,” she added.
Bryan Matthews, a lecturer at the Institute for Transport Studies at the University of Leeds, shares the concerns about cost. He says there should also be a focus on inclusive design, and anything that helps people navigate their environment is positive.

6 . Many students study by reading their notes and textbooks over and over again. But studies show there are more effective ways to help you study smarter.
Don’t just reread.
Find examples. Abstract concepts can be hard to understand. It tends to be far easier to form a mental image if you have a concrete example of something.
Dig deeper. It’s hard to remember countless facts and figures if you don’t push further. Ask why things are a certain way. How did they come about? Why do they matter? Psychologists call this elaboration(深究). It’s taking class material and asking many how and why questions about it.
Practice more. Musicians practice their instruments. Athletes practice sports skills.
As a teen, Cynthia Nebel studied by reading her textbooks, worksheets and notebooks. “Over and over and over again,” recalls this psychologist at Vanderbilt University in Nashville, Tenn. Now, she adds, “we know that’s one of the most common bad study skills that students have.”
A.Make a budget and save it. |
B.Make a plan and stick to it. |
C.The same should go for learning. |
D.However, not all can apply to students. |
E.In other words, don’t just accept facts at face value. |
F.Sadly, reading books and notes repeatedly is common for many students. |
G.For instance, sour foods usually taste that way because they contain an acid. |

8 . Modern technology has a strong influence on every part of our life, including the education in the universities.
Ashok Goel, a professor of Georgia Institute of Technology, says he uses the Internet in almost all of the classes he teaches. Every term over 300 graduate students take his class on artificial intelligence (人工智能). The students never meet in person. All of the classes take place online — through a website, which lets students ask questions and complete their work from anywhere in the world.
Having hundreds of students in a class means Ashok Goel has to answer thousands of questions. He has eight teaching assistants to help him. But even that is not enough to give all the students the help they need.
So, in January, Goel had an idea. He decided to try an experiment. At the start of the spring 2016 term, he added a new member to his teaching team: Jill Watson. She was able to answer questions faster than most other teaching assistants. And she was available 24 hours a day.
It was only at the end of the term that Goel’s students learned Watson’s true identity: she was not a real person like the other teaching assistants. Jill Watson was an AI computer program.
And it seems Goel’s stories will become more common in the universities.
A website called Campus Technology publishes stories about how colleges and universities use new technology. In August, the site published a survey of over 500 professors and their use of technology. Fifty-five percent of the professors asked students to use study materials online before coming to class. And, more than 70 percent combined (使相结合) online materials and face-to-face teaching in their classrooms.

C.Modern technology greatly influences college education. |
D.Teachers will be completely replaced by the computers. |
9 . Diplomacy (外交) is an art. It requires not only strategy, but also other aspects, including intuition, persuasion, and even tricks, human skills that have long been unreachable to even the most powerful artificial intelligence (AI) approaches. Now, an AI algorithm (算法) from a high-tech company has shown it can beat many humans in a game of diplomacy, which required both strategic planning and negotiations with other players. The work, researchers said, could point the way toward virtual exercise coaches and conflict mediators (调解员) .
AI has already beaten humans in some games of strategy. It is also proving powerful at natural-language processing, in which it can generate humanlike text and carry on conversations. In the game of diplomacy, seven players vied for control of Europe. On each turn, players issued orders regarding the movement of army and naval units, following discussion with other players, whom they could attack or support.
There are two technical innovations noted by Jonathan Gratch, a computer scientist at the University of Southern California who studies negotiation agents. First, the Al agent’s com-munication is grounded in multistep planning. Second. the Al agent keeps its remarks and game play within the range of human common practice.
To test its skill, the researchers had the Al agent play 40 online games against humans. It placed in the top 10% of players who’d played at least two games. “In a game that involves language and negotiation, that agents can reach human equal level is very exciting,” said Yu, a computer scientist at Columbia University.
According to Brown, a computer scientist at the company who co-authored the paper, the work could lead to practical applications in fields that now require a human touch. One specific example is that virtual personal assistants might help consumers negotiate for better prices on plane tickets. Gratch and Yu both see opportunities for agents that persuade people to make healthy choices or open up during therapy.
