Chimps(黑猩猩) will cooperate in certain ways, like gathering in war parties to protect their territory. But beyond the minimum requirements as social beings, they have little instinct (本能) to help one another. Chimps in the wild seek food for themselves. Even chimp mothers regularly decline to share food with their children, who are able from a young age to gather their own food.

In the laboratory, chimps don't naturally share food either. If a chimp is put in a cage where he can pull in one plate of food for himself or, with no great effort, a plate that also provides food for a neighbor to the next cage, he will pull at random —he just doesn't care whether his neighbor gets fed or not. Chimps are truly selfish.

Human children, on the other hand are naturally corporative. From the earliest ages, they decide to help others, to share information and to participate in achieving common goals. The psychologist Michael Tomasello has studied this cooperativeness in a series of experiment with very young children. He finds that if babies aged 18 months see an unrelated adult with hands full trying to open a door, almost all will immediately try to help.

There are several reasons to believe that the urges to help, inform and share are not taught, but naturally possessed in young children. One is that these instincts appear at a very young age before most parents have started to train their children to behave socially. Another is that the helping behaviors are not improved if the children are rewarded. A third reason is that social intelligence develops in children before their general cognitive（认知的）skills, at least when compared with chimps. In tests conducted by Tomasello, the human children did no better than the chimps on the physical world tests but were considerably better at understanding the social world.

The core of what children's minds have and chimps' don't is what Tomasello calls shared intentionality. Part of this ability is that they can infer what others know or are thinking. But beyond that, even very young children want to be part of a shared purpose. They actively seek to be part of a “we”, a group that intends to work toward a shared goal.

    Maybe it is true that we do not know what we have got until we lose it,but it is also true that we do not know what we have been missing until it arrives.

    It takes an hour to like someone,and a day to love someone,but it takes a lifetime to forget someone.Giving someone all your love is never an assurance that they will love you back.Do not expect love in return;but if it does not,be content it has grown in yours.Do not rely on one's appearance;it can trick you.Do not rely on wealth;even that fades away.Rely on someone who makes you smile,because it takes only a smile to make a dark day seem bright.

    There are moments in life when you miss someone so much that you just want to pick them from your dreams and hug them.Dream what you want to dream;go where you want to go;be what you want to be,because you have only one life and one chance to do all the things you want to do.

    The brightest future will always be based on a forgotten past.You cannot go on well in life until you let your past failures and heartaches go off.May you have enough happiness to make you sweet,enough trails to make you strong,enough sorrow to keep you human,enough hope to make you happy.The happiest of people do not necessarily have the best of everything;they just make the most of everything that comes along their way.Happiness waits for those who cry,those appreciate the importance of people who have touched their lives.Always put yourself in others' shoes.If you feel that it hurts you,it probably hurts the other person,too.

    When you were born,you were crying and everyone around you was smiling.Live your life so that when you die, you are the one who is smiling and everyone around you is crying.

    Some people will do just about anything to save money. And I am one of them. Take my family's last vacation. It was my six-year-old son's winter break from school, and we were heading home from Fort Lauderdale after a week long trip. The flight was overbooked, and Delta, the airline, offered us $400 per person in credits to give up our seats and leave the next day. I had meetings in New York. So I had to get back. But that didn't mean my husband and my son couldn't stay. I took my nine-month-old and took off for home.

    The next day, my husband and son were offered more credits to take an even later flight. Yes, I encouraged—okay, ordered—them to wait at the airport, to “earn” more Delta Dollars. Our total take: $1,600. Not bad, huh?

    Now some people may think I'm a bad mother and not such a great wife either. But as a big-time bargain hunter, I know the value of a dollar. And these days, a good deal is something few of us can afford to pass up.

    I've made a living looking for the best deals and exposing (揭露) the worst tricks. I have been the consumer reporter of NBC's Today show for over a decade. I have written a couple of books including one titled Tricks of the Trade: A Consumer Survival Guide. And I really do what I believe in.

    I tell you this because there is no shame in getting your money's worth, I'm also tightfisted when it comes to shoes, clothes for my children, and expensive restaurants. But I wouldn't hesitate to spend on a good haircut. It keeps its shape longer, and it's the first thing people notice. And I will also spend on a classic piece of furniture. Quality lasts.

    Some people are never right. They never have good luck. They usually do the wrong things and say the wrong things. And even if what they say and do is OK, they say it or do it at the wrong time. So these people always have problems. They often break glasses. They sometimes miss buses or trains.

    Mr. Neff is different. He is always right. He is never wrong. He usually has good luck. He hardly has problems. He never misses buses and trains. Even though he really misses them, it is always the fault of the buses and the trains.

    Mr. Neff knows almost everything. He doesn't ask questions. He answers questions. He never says “I don't know”．

    I don't know Mrs. Neff. It seems that not many people know her. I sometimes want to know about her. Is she always right? Or maybe she is always wrong? Does she often break glasses or miss buses and trains?

Does she have problems? I really want to know!

    Healthy habits mean healthy eyes. Here are some daily tips for eye health.

    P Clean your eyes with pure cold water regularly. This is one of the best ways to keep eyes healthy and disease free.

    Roll your eyes up and down, then side to side. Then move your eyes in a circular motion（圆周运动） Exercise5tol0 times a day to relax your eyes

    Keep a good distance from the computer screen-sit about 22-28 inches away from it.

    Visit your eye doctor on a regular basis

    There are also some tips for healthy contact lens（隐形眼镜）wear and care to help prevent eye infections (感染). Please visit CDCS healthy contact lenses website and you can also follow them on social media(www.cdc.goy/contactlenses).

    "You know, the soft subjects," says the boy in maths. "The easy ones: the stupid girls at the bottom take them. Like dance. It shouldn't even be a subject." We're choosing subjects for our A-level taster day at school. I see the raised eyebrows (眉毛) when I explain two of my GCSE (General Certificate of Secondary Education) choices are dance and drama(戏剧).

    I was told by advisers that dance and drama wouldn't help me to get a suitable career. My friends told me I'd get bored of dance and switch to science within the first month.

    But taking GCSE dance was the best decision I ever made. Dance gives me something to pour my head and heart into. It gives me a feeling of belonging, creativity, security and freedom.

    The education secretary Nicky Morgan has put emphasis on (强调) science, technology, engineering and maths (STEM), saying that students who focus on the arts risk their careers. Stopping young people from expressing themselves at such a young age is not doing them any favours. Perhaps Nicky Morgan has forgotten to open the door of having a drive to study that subject day in, day out. It shouldn't matter what that subject is.

    I don't doubt the influence that STEM subjects can have on the people that love them. But to force children into one field is cruel. As much as I try, I'm not good at and don't love physics, biology or maths. I don't want a career in these areas.

    There has been a decrease in the number of state schools offering arts subjects taught by specialist teachers. I can't even imagine how it feels to be told that you don't teach a "real subject" by an 8-year-old boy.

    To the teachers, the parents, the government I say: Let children make their own decisions. Let them live in the present. Let them have a real, unlimited education.
