Every time we get behind the wheel of a car, we put our lives and the lives of others at risk. Self-driving cars are designed to reduce those risks by letting technology control our vehicles.

    Accident rates for self-driving cars have been much lower than the rate, for human-driven cars. {#blank#}1{#/blank#}

    As humans, we can make moral choices in avoiding accidents. To avoid hitting a child, for example, human drivers might sharply turn a car away from the child even if others may be injured. {#blank#}2{#/blank#} Researchers studied this issue. They have developed the Moral Machine website to help explore the choices self-driving cars should make.

    {#blank#}3{#/blank#} You are shown two possible traffic situations and you choose between them. An accident will take place. You choose how many living beings would be hurt or killed.

    In one situation there may be a female doctor, a child, two dogs and a homeless person who would be killed. In the other situation, you might have two babies and a cat who would be killed. {#blank#}4{#/blank#}

    The Moral Machine website has many situations and many possible outcomes. When you click on the situation of your choice, it will be highlighted. {#blank#}5{#/blank#} At the end of the situation, you are shown the results, based on the choices you made. The results show which character you were most likely to save and which character you were most likely to have die.

    I just counted how many foreign languages I've studied so far in my life and it's been twelve!

    I always follow my interests and find ways to put my language learning into things I'm already interested in. I like to read blogs(博客)in other languages.{#blank#}1{#/blank#}. For the most part, bloggers tend to write the same way they speak, so I don't have to worry much about adopting strange terms that are only used in writing.

    Movies are also a really good tool, especially if you can find subtitles in the language you're learning.{#blank#}2{#/blank#}, they will still keep your brain listening and reading in the same language. Music is another way to start listening to things in your new language. Personally, I'm so bad at understanding lyrics(歌词)even in English, so this one doesn't really work for me, but I have friends who learn a language through lyrics. Games are of course also an excellent way of studying a new language. A lot of language learning computer programs include games. I'm super competitive and if I play any of them, I can be hooked for hours.{#blank#}3{#/blank#}.

    When the initial excitement of learning a new language begins to fade, it can be hard to stick with it. The hardest bit for me is when I'm comfortable enough with a language to understand most things and make myself understood. I'm actually stuck at this stage in Norwegian.{#blank#}4{#/blank#}. Ideally I should sign up to take a big language exam. Each time I start getting self-satisfied, it's time to take a new course or sign up for online lessons, or take up some sort of challenge that will require me to level up my skills.

    {#blank#}5{#/blank#}. The best language class I've ever taken was my beginner's Russian course at university where my professor never used any English. It got to the point where I would kind of just forget about English while in Russian class, which helped me to really immerse myself in the Russian language and do a whole lot with the limited Russian I had.

A. That's really uncomfortable

B. Whatever languages they're translated into

C.I also try to think in the language I'm learning

D. It's time well spent if I'm learning the language

E. Computer games always make me feel worn out

F. Though they don't always exactly match what's being said

G.I found them the perfect learning tool because they're usually written in oral language

    Here are some top tips for world travelers.

    Make false eye contact

If a person is lying he may feel you are watching him and he will look down at the floor or away from your eyes. Some people try to stare at you in the face in a deliberate way. {#blank#}2{#/blank#}.

    Avoid using contractions (缩略语)

    The liars will say "I did NOT notice your money", instead of "I didn't notice your money". This is an attempt by the liars to be absolutely clear what they mean. {#blank#}3{#/blank#}.

    {#blank#}4{#/blank#}

    Liars often feel uneasy, turn away from the person to whom they are speaking, blink rapidly, smile less and have pitch changes in their tone of voice. They may cross their arms which is a sign of being "closed" or trying not to reveal too much information. They could touch parts of their face, an ear or a nose or play with keys or another item that they have in their hand.
