Recent studies have shown that there is a link between anxiety and intelligence and it is a positive one.Fear allows you to react to a potential threat in good time.Being too happy all the time means that you don't think about potential problems.{#blank#}1{#/blank#}But the response means that their imagination is highly active.An active imagination keeps you safe from threats.

    The general belief about anxiety is that it's a negative thing.Because suffering from anxiety is not pleasant,most of the people who deal with it hope they don't have to.{#blank#}2{#/blank#}Science is showing that a little bit of anxiety is a good thing.

    In 2002,Israeli psychologists ran a test on 80 students.The students were under the impression mat they were there to appreciate artwork on a piece of software.However,the researchers rigged（在…上做手脚）the program.{#blank#}3{#/blank#}So they were men encouraged to contact IT.

    Finding IT brought new challenges.As the students left the room,they met various problems.{#blank#}4{#/blank#}someone also stopped them to ask them to complete a survey.The test found that the participants who really wanted to reach IT to fix the virus had the highest amount of anxiety.The students who had less anxiety couldn't focus.They stopped to complete the survey,pick up the papers,etc.

    Obviously,the anxious students had a greater sense of the threat.{#blank#}5{#/blank#}Therefore,anxiety can actually give us higher chance to succeed!

A.So when does worry become a bad thing?

B.Thus,they tried their best to achieve their goal.

C.But this does not necessarily need to be the case.

D.Some students came across dropped papers as they walked by.

E.Instead of viewing artwork,the students found a computer virus.

F.Often kids and adults with anxiety have a very negative view of themselves.

G.People with anxiety are sometimes responding to a threat that doesn't exist.

    When I was about 12, I had an enemy, a girl who liked to point out my shortcomings(缺点). Week by week her list grew: I was very thin, I wasn't a good student, I talked too much, I was too proud, and so on. I tried to hear all this as long as I could. At last, I became very angry. I ran to my father with tears in my eyes.

    He listened to me quietly, and then he asked, “Are the things she says true or not? Janet, didn't you ever wonder what you're really like? Well, you now have that girl's opinion. Go and make a list of everything she said and mark the points that are true. Pay no attention to the other things she said.”

    I did as he told me. To my great surprise, I discovered that about half the things were true. Some of them I couldn't change (like being very thin), but a good number I could—and suddenly I wanted to change. For the first time I got a fairly clear picture of myself.

    I brought the list back to Daddy. He refused to take it. “That's just for you,” he said. “You know better than anyone else the truth about yourself. But you have to learn to listen, not just close your ears in anger and feel hurt. When something said about you is true, you'll find it will be of help to you. Our world is full of people who think they know your duty. Don't shut your ears. Listen to them all, but hear the truth and do what you know is the right thing to do.”

    Daddy's advice has returned to me at many important moments. In my life, I've never had a better piece of advice.

    In an ideal world, people would not test medicines on animals. Such experiments are stressful and sometimes painful for animals, and expensive and time-consuming for people. Yet animal experimentation is still needed to help bridge vast gaps in medical knowledge. That is why there are some 50 to 100 million animals used in research around the world each year.

    Europe, on the whole, has the world's most restrictive (严格的) laws on animal experiments. Even so，its scientists use some 12 million animals a year, most of them mice and rats, for medical research. Official statistics show that just 1.1 million animals are used in research in America each year. But that is misleading. The American authorities do not think mice and rats are worth counting and, as these are the most common laboratory animals, the true figure is much higher. Japan and China have even less comprehensive (全面的) data than America.

    Now Europe is reforming the rules governing animal experiments by restricting the number of animals used in labs. Alternatives to animal testing，such as using human tissue or computer models, are now strongly recommended. In addition, sharing all research results freely should help to reduce the number of animals for scientific use. At present, scientists often share only the results of successful experiments. If their findings do not fit the hypothesis (假设) being tested, the work never sees the light of day. This practice means wasting time, money, and animals' lives in endlessly repeating the failed experiments.

    Animal experimentation has taught humanity a great deal and saved countless lives. It needs to continue，even if that means animals sometimes suffer. Europe's new measures should eventually both reduce the number of animals used in experiments and improve the way in which scientific research is conducted.

    Are you interested in higher education in the United States? The following advice might help you.

    College, University or Institute

    College and universities offer undergraduate degrees in arts and sciences. And both can help prepare young people to earn a living. But many colleges don't offer graduate studies. Universities are generally bigger, offer more programs and do more research. An institute of technology can offer a wide choice of programs and activities. Seventy-five percent of freshmen go there with a strong interest and involvement in the arts.

    The Application Process

    International admissions officers advise students to apply to at least three schools. You may be able to apply online and pay the application charge with a credit card, or by mail. You should study the websites of schools to find information about how and when to apply, how much it will cost and whether any financial aid is available.

    Get a Student Card

    If you request a visa for the first time, you will have to go to an American embassy or consulate(领事馆). You will need to bring a government form sent to you by your American school that shows you have been accepted. A consular official will also take your picture and your fingerprints. You will also need banking and tax records that show you have enough money to pay for your education.

    Financial Aid

    American schools provide aid, like scholarships, fellowships, to almost half of foreign graduate students, but only ten percent of undergraduates. But grants, which, unlike a loan, does not have to be paid.

    Humans were designed to stand upright. And yet in this modern world, too many of us spend our days with our heads lowered for a simple reason: we're staring at the tiny screen of a smart phone.

    People spend an average of 2 to 4 hours each day with their neck bent while shooting off emails or texts. That's 700 to 1,400 hours a year. The success of social media has led to a rapid development of bad smart phone posture(姿势).

    The average adult head weighs 10 to 12 pounds when it's in the upright position. However, because of the gravity, bending your head at a 15 degree puts 27 pounds of pressure on your spine(脊椎); a 30 degree neck bend could equal 40 pounds of pressure; a 45 degree bend adds the force of 49 pounds, according to the research from Dr. Kenneth Hansraj from New York. These stresses may lead to many problems.

    It's no secret that correct posture is better for your back. According to the researchers, good posture is described as ears aligned(成一条直线) with the shoulders. In proper alignment, spinal stress disappeared. It is the best position for the spine. Standing tall doesn't just make you look better; it improves your health, too. Other studies have found good posture has even been connected to ways of behaving. People who have poorer posture often have poorer physical and emotional health.

    The researchers describe bad posture as “the head in a forward position and the shoulders dropping forward in a rounded position”. Bad posture has been connected to many medical problems, including headaches and other problems, depression and heart disease. This is why Hansraj said it's important to be mindful of your smart phone posture. Though it is nearly impossible to avoid the technologies that cause these problems, people should make an effort to look at their phones with a correct posture.

    Here's the story of my growth over the past year. If anyone is inspired (激励) by this, that's wonderful.

    I'd been stuck as this under-confident, fat and just frightened girl for years and years and years. Since I was a little girl, I'd been stuck like this, and I had lived a life where I'd be afraid of everything. But then it all started changing. Something clicked, and in over a period of 6 months I finally managed to stick to one of my diets, bringing me from overweight straight down to underweight. This proved (证明) that I could change myself.

    One single time, I heard about a public speaking thing going on at my university, and for the first time, I managed to keep up the courage to go there. For the first time I was able to share my story, and able to do it in front of so many people possibly judging (评判) me, and suddenly all the fears about speaking publicly started vanishing. I never felt more confident.

    This taught me I could get rid (去除) of my fears  It was from that point on that my road to change went from a rocky mess to a full-on empty highway.

    Using the fact that I could change, and that I could get rid of my fears, I started working on them one by one. My fear of talking to strangers ,my fear of asking simple questions, my fear of hanging out with people, my fear of being myself... All of them were gone. And I still continue to progress to this day. I've never stopped.
