Tonight, my piano recital(钢琴演奏会) was the most important thing in my family. My grandparents were coming by plane to hear me play. Even my busy Aunt Dianne, who is on TV every night reading the news, was coming.

    But one thing was for sure. I would never win an award for my piano playing. And that's just because the more I practiced, the more nervous I got. So there I was，on the stage， in my beautiful dress，and I sat down at the piano. But when I started to play，I hit a wrong note. I told myself to start over. But then I hit the wrong note again. It was as if I hadn't practiced at all.

    Finally the disaster was over. I ran off the stage. I couldn't understand why audience(观众) were clapping. But they were. My mom and dad had flowers for me and we were all supposed to go out for a nice dinner, but I couldn't. I just wanted to go home and cry and never go anywhere again. After we went back home, Aunt Dianne just came in and sat down on the side of my bed.

    “It was my first night on the air,” she said. “I had never been on television before and I made a mistake. I mispronounced my name and the name of the news show. And you know what? No one even noticed but me. Just like tonight, no one noticed—just you.” Aunt Dianne was right. I think we are harder on ourselves than anyone else is. Maybe I will leave my room. And maybe I'll play the piano again.

    Picture the scene: You come home after work feeling too exhausted to cook –only to find a delicious meal worthy of a Michelin-starred restaurant waiting for you. It sounds like a fantasy, but it could be about to come true thanks to a robot chef developed by British scientists.

    Those scientists have come up with a set of robotic arms so smart that they are capable of cooking meals all by themselves. The device will be sold from as early as 2017 as part of a purpose-built high-tech kitchen.

    Scientists at Moley Robotics spent almost 18 years developing the hands. According to its creators, the arms can chop, stir, whisk and baste well enough to recreate almost anything you would care to eat, whether it is a simple home-cooked supper, or a complicated creation designed by a world-class chef. The hands move a little slowly, hovering strangely above the work surface whenever they are not busy, but they imitate human movements closely enough that they can do things such as wiping a spoon on the edge of a pan to prevent drips.

    Mr Oleynik, who is leading the project, said, “All the things which are possible with the hand are possible here. There is no limitation. A lot of people want to go to Michelin-starred restaurants, but they are quite expensive and may be quite far from the home. This is an opportunity for people to enjoy very good food, and for a reasonable price. ”

    The only cuisine that is off the robot's menu at the moment is sushi, which requires extremely steady pressure and nimble（敏捷的；敏感的） fingers to make, but the team plan to conquer that as well by the time it goes on sale.

    So long as teachers fail to distinguish between teaching and learning, they will continue to undertake to do for what only children can do for themselves. Teaching children to read is not passing reading on to them. It is certainly not endless hours spent in activities about reading. Douglas insists that "reading cannot be taught directly and schools should stop trying to do the impossible."

    Teaching and learning are two entirely different processes. They differ in kind and function. The function of teaching is to create the conditions and the climate that will make it possible for children to devise the most efficient system for teaching themselves to read. Teaching is also a public activity: It can be seen and observed.

    Learning to read involves all that each individual does not make sense of the world of printed language. Almost all of it is private, for learning is an occupation of the mind, and that process is not open to public scrutiny. If teacher and learner roles are not interchangeable, what then can be done through teaching will aid the child in knowledge. Smith has one principal rule for all teaching instructions. "Make learning to read easy, which means making reading a meaningful, enjoyable and frequent experience for children."

    When the roles of teacher and learner are seen for what they are, and when both teacher and learner fulfill them appropriately, then much of the pressure and feeling of failure for both is eliminated. Learning to read is made easier when teachers create an environment where children are given the opportunity to solve the problem of learning to read by reading.

    Animals, including insects, do not have a language like ours. They do not talk to each other in words and sentences. But if we watch them, we can see that they do have ways of communicating with each other.

    Can you see the rabbits' tail? When rabbits see this white tail moving up and down, they run too. The rabbit has reminded them of potential dangers without making a sound. It has given them a signal.

    Many other animals use this kind of language. When a cobra(眼镜蛇) is angry, it raises its hood(兜帽) and makes itself look fierce. This warns other animals. When a bee has found some food, it goes back to its home. It cannot tell the other bees where the food is by speaking to them, but it does a little dance in the air. This tells the bees where the food is.

    Some animals say things by making sound. A dog barks, for example, when a stranger comes near. A cat purrs(猫的呜呜声) when pleased. Some birds make several different sounds, each with its own meaning. Sometimes we human beings speak in the same way. We make sounds like “Oh” or “Ah!” when we are frightened or pleased or when we drop something on our toes.

    But we have something that no animals have a large number of words which have the meanings of things, actions, feelings or ideas. We are able to give each other all kinds of different information in words and sentences, which no other animals can do. No other animals have so wonderful a language as we have.

Unhealthy health care bills, long emergency-room waits and inability to find a primary care physician just scratch the surface of the problems that patients face daily.

Primary care should be the backbone of any health care system. Countries with appropriate primary care resources score highly when it comes to health outcomes and costs. The U.S. takes the opposite approach by emphasizing the specialists rather than the primary care physician.

A recent study analyzed the providers who treat Medicare Beneficiaries(老年医保受惠人). The startling finding was that the average Medicare patient saw a total of seven doctors — two primary care physicians and five specialists — in a given year. Contrary to popular belief, the more physicians taking care of you don't guarantee better care. Actually increasing breakup of care results in a corresponding rise in costs and medical errors.

How did we let primary care slip so far? The key is how doctors are paid. Most physicians are paid whenever they perform a medical service. The more a physician does, regardless of quality or outcome, the better he's reimbursed (返还费用). Moreover, the amount of a physician receives leans heavily toward medical or surgical procedures. A specialist who performs a procedure in a 30-minute visit can be paid three times more than a primary care physician using that same 30 minutes to discuss a patient's disease. Combine this fact with annual government threats to indiscriminately cut reimbursements, physicians are faced with no choice but to increase quantity to boost income.

Primary care physicians who refuse to compromise quality are either driven out of business or to cash-only practices, further contributing to the decline of primary care.

Medical students are not blind to this scenario. They see how heavily the reimbursement deck is stacked against primary care. The recent numbers show that since 1997, newly graduated U.S. medical students who choose primary care as a career have declined by 50%. This trend results in emergency rooms being overwhelmed with patients without regular doctors.

How do we fix this problem?

It starts with reforming the physician reimbursement system. Remove the pressure for primary care physicians to squeeze in more patients per hour, and reward them for optimally managing their diseases and practicing evidence-based medicine. Make primary care more attractive food to medical students by forgiving students loans for those who choose primary care as a career and harmonizing the marked difference between specialist and primary care physician salaries.

We're at the point where primary care is needed more than ever. Within a few years, the first wave of 76 million Baby Boomers will become qualified for Medicare. Patients older than 85, who need chronic care most, will rise by 50% this decade.

Who will be there to treat  them？

Every year on April 1,April Fools' Day is celebrated in many countries around the world.In France,it's called "Poisson d' Avril"or"Fish of April".In Scotland, the holiday is often called "Gowkie Day".In Iraq, the holiday is called "Kithbet Neesan" or "April Lie".

In the United State, April Fools' Day is just a day of joking and playing tricks on friends.These kinds of jokes are also called pranks(恶作剧).These jokes typically end in the prankster shouting "April Fools"!

Simple pranks, like telling a friend a funny lie or making prank phone calls, are still common.But major companies also get in on April Fools' Day in a much bigger way.A few years ago,on April 1,Starbucks announced it was introducing new coffee cup sizes-plenta and Micra.The very large cups,bigger than a human head,remained useful for customers even after finishing all that coffee.According to Starbucks,the cups could be used as a rain hat,a pot for plants,or a lampshade.

It did not take long for customers to catch on to the prank.More and more people use media or smartphone apps to play pranks on their friends on April Fools' Day.One very annoying smartphone app,Cat Facts,sends funny facts about cats to your friends 5 phones every day.
