The defeat of Lee Sedol, the world's strongest Go (围棋) player, by a Google artificial intelligence (AI) program, looks like another milestone towards a world where computers can do almost anything a human can. It is not. There are uncountable things that only a human can do, and that no computer seems close to. The problem is that the purely human things are not economically useful to anyone. The things that computers can be taught to do are by contrast economically fantastic. But even the most powerful programs are not human, just as a shovel (铲车). They have no feelings. What they have is power, but this power is growing at a rate that should frighten us all.

    It might be less frightening if computers were truly intelligent, but even the most powerful networks are less human than monstrous Martians (火星人). Their power will be used to make money for the firms that finance their development, and then for others quick and clever enough to take advantage of the new world. It is far more likely that they will increase inequality and still further remove the middle classes as we move towards an hourglass (以金钱来衡量的) society in which everyone is either very rich or very poor and likely indebted.

    One of the ill effects of the spread of more intelligent computer networks is, at the same time, the spread of what might be called artificial stupidity. If AI is employed largely to replace unskilled labour, it is most productive when labour is kept unskilled or redefined that way. So much of the work in service industries is now simplified until it might be automated (自动化). And robots will never need pensions(养老金). AI is slowly reducing skilled work, like some forms of medical diagnosis (诊断), at the same time, as older doctors complain that the traditional human skills of diagnosis are falling out of medical training. The belief that everything worthwhile can be measured and then managed is far more damaging to humanity than the threat of artificial intelligence on its own.

    But no victory in complicated Go games can bring us closer to truly human-like computers.

    When I was 3 years old, I was found to be deaf in my left ear and have a small problem in my right. Being hard of hearing has been difficult, but I've never lived in a state of self-hating sorrow.

    Imagine being able to shut out all sounds as you lay your head down to sleep by simply rolling over onto one side. That's my reality when I sleep on my “good ear”, and it even makes me feel like a superhero sometimes.

    People call my deaf side my “bad ear”, but when I wear my hearing aid, I have access to a range of features(特征)that some other deaf people don't.

    In cinemas, for example, with one click of a button I can enjoy a whole film as though it were whispered to me from the mouths of the actors.

    Having a hearing aid hasn't always felt good, however.

    On the first day I got my aid, when I was 8, I took it to school for show-and-tell. As I explained how it worked to my classmates, a boy yelled out, “Aren't those for old men?”

    At that moment, I felt different. It took a long time for me to get over that sense of being so unlike my peers(同龄人).

    But it's not just choolkids who can make us deaf and hard-of-hearing people feel like burdens(负担).

    Every video on social media that lacks subtitles, for example, means an entire community of deaf people is unable to enjoy it.

    Completely deaf people are excluded from enjoying many movies too, as subtitles in cinemas are almost impossible to find.

    And with hearing aids costing around $2,500 each, it can be hard for many people to afford to be able to listen to the things that others take for granted.

    As for me, I can listen to music, enjoy films, and catch conversations – I'm lucky.

I'm deaf, but I can still hear everything. I've been blessed with wonderful life experiences.

    Think plants are just boring green things that you use for food and decoration? Think again! Plants are able to do some pretty awesome things that you're probably totally unaware of.

    Researchers have discovered that plants have the ability to communicate with an underground network made up of fungus (真菌) , which serves the plants in many ways. Tomato plants use the fungus web to warn each other of their own unhealthy conditions. Trees connected through the fungus network could move nutrients (养分) to and from each other. It is believed that larger trees move nutrients to smaller ones to help them to survive.

    Not only that, but they can also damage unwelcome plants by spreading poisonous chemicals through the fungus. It sounds like the plant world had the Internet before we did.

    Some plants have a rather impressive line of defense against being eaten. When sensing they are being swallowed, they give off a chemical into the air that attracts the insect's natural enemy. The enemy attacks the bug, thus saving the plants. This is basically the plant kingdom version of getting your older brother to beat up that kid who steals your lunch money.

    You might be aware that humans and animals have an internal clock. But did you know that plants also have this clock? This means they can prepare for certain times of day just like we do. Is it because they can react to light at sunrise? In a study, scientists found that plants use the sugars they produce to keep time, which help to regulate the genes responsible for the plant's own internal clock. So, in a sense, wake up with petunias (矮牵牛) is just as valid as ―wake up with the chickens.

    Nature is full of surprises. So for those of you who didn't know the wonders of plants, now you do.

    You can't see your sleeping pets brain waves, but its behavior can tell you when your cat might be dreaming. If you watch closely, you'll see that as she falls asleep, her breathing becomes slow and regular with her body still. She has entered the first stage of sleep, called slow-wave sleep. After about 15 minutes you'll notice a change in her breathing. Her eyes move under her closed lids, her paws twitch (抽动) and she flicks (尤指用手指或手快速地轻抚) an ear. She has entered dreaming. Although she twitches and makes little grunting (嘟嘟) noises, messages from her brain to the large muscles in her legs are blocked, so she can't run about. She is in a state of "sleep paralysis (麻痹)".

    Michel Jouvet, a French scientist, interrupted their sleep paralysis. Even though they were completely asleep, the dreaming cats began to run for balls that Jouvet couldn't see and arched (弓起) their backs at unseen enemies. He figures he was watching them act out their dreams! Obviously, the dreaming cats seemed to be practising important cat skills: following, pouncing (猛扑), and fighting.

    In another study, Matt Wilson recorded rats brain waves while they learned mazes (迷宫). One day, he left the brain-wave-recording machine on while the rats fell asleep. The pattern of brain waves in the sleeping rats matched the pattern from the maze so closely that Wilson could figure out exactly which part of the maze each rat was dreaming about!

    Many researchers now think that in both people and animals, one purpose of dreams is to practise important skills and figure out recent caning. This may explain why so many people dream about fighting and escaping, skills that were probably important to our ancestors, and why dreaming affects our ability to learn.

    Do all animals dream? From looking at the brain waves of sleeping animals. How often animals dream seems to be tied to body size. Cats dream about every 15 minutes, mice every 9 minutes, and elephants every 2 hours. And though cows and horses usually sleep standing up, they only dream when lying down.

Sometimes the toughest thing about feelings is sharing them with others. Sharing your feelings helps you whether your feelings are wonderful or terrible. Sharing also helps you to get closer to people you care about and who care about you. But how?

 You can't tell your friends what's inside our backpack if you don't know what's in there yourself. {#blank#}1{#/blank#} Before you can share them with anyone, you have to figure out what feelings you have. {#blank#}2{#/blank#} You can do this in your mind or by writing them out or even by drawing pictures. Is something bothering you? Does it make you frustrated or terrified? Do you feel this emotion only once in a while or most of the time?

 The way a person feels inside is important. If you keep feelings locked inside, it can even make you feel sick! {#blank#}3{#/blank#} It doesn't mean your problems and woes magically disappear, but at least someone else knows what's bothering you and can help you find solutions.

 Your mom and dad want to know if you have problems and what's happening in your life. But what if a kid doesn't want to talk with parents? Then find another adult you trust like a relative or a teacher at school. {#blank#}4{#/blank#}

 Once you know who you can talk with, you'll want to pick a time and place to talk. You can talk publicly in your family. But some kids are more private than others and they will feel shy about sharing their feelings. {#blank#}5{#/blank#} A kid doesn't have to share every feeling he or she has.
 

A.Feelings are the same way.

B.Making a list of your feelings can help.

C.And there is always a person you can turn to.

D.Thinking about what you can do is of great importance.

E.Then find a quiet place or write it down on a piece of paper.

F.But if you talk with someone who cares for you, you will almost always start to feel better.
