Success is often measured by the ability to overcome adversity（逆境）. But it is often the belief of others that gives us the courage（勇气）to try.
J. K. Rowling, author of the Harry Potter book series, began writing at age 6. Her good friend-Sean became the first person to encourage her and help her build the confidence that one day she would be a very good writer.
“He was the first person with whom I really discussed my serious ambition（志向） to be a writer. He was also the only person who thought I was bound to（注定）be a success at it, which meant much more to me than I ever told him at the time.”
Though there were many difficulties, Rowling continued her writing, particularly fantasy stories. But it wasn't until l990 that she first came up with the idea about Harry Potter. As she recalls（回忆）, it was on a long train journey from London to Manchester that “the idea of Harry Potter simply fell into my head. To my great disappointment, I didn't have a pen with me, and I was too shy to ask anybody if I could borrow one. I think, now, that this was probably a good thing, because I simply sat and thought, for four (delayed train) hours, and all the details came up in my brain, and this thin, black-haired, bespectacled（戴眼镜的）boy who didn't know he was a wizard became more and more real to me.”
That same year, her mother died after a ten-year fight with serious diseases, which deeply affected her writing. She went on to marry and had a daughter, but separated from her husband shortly afterwards.
During this time, Rowling was diagnosed with depression（诊断患有抑郁症）. Unemployed, she finished her first novel in area cafes, where she could get her daughter to fall asleep. After being refused by l2 publishing houses, the first Harry Potter novel was sold to a small British publishing house.
Now with seven books that have sold nearly 400 million copies in 64 languages, J. K. Rowling is the highest earning novelist in history. And it all began with her friend’s encouragement as well as her ambition to write.
【小题1】 Who believed J. K. Rowling was to be a good writer?

There is an English saying :“laughter is best medicine .”Until recently ,few people took the saying seriously .Now however ,doctors have begun to look into laughter and the effects it has on the human body .They have found that laughter really can improve people’s health .
Tests were carried out to study the effects of laughter on the body .People watched funny films while doctors checked their hearts ,blood pressure ,breathing and muscles .It was found that laughter had similar effects to physical exercise .It increases blood pressure ,the heart beating and breathing ; it also works several groups of muscles in the face ,the stomach ,and even the feet .If laughter exercises the body ,it must be beneficial .
Other tests have shown that laughter appears to be able to reduce the effect of pain on the body .In one experiment doctors produced pain in groups of students who listened to different radio programmes .The group that tolerated(忍耐)the pain for the longest time was the groups which listened to a funny programme .The reason why laughter can reduce pain seems to be that it helps to produce a kind of chemicals in the brain which diminish both stress and pain .
As a result of these discoveries ,some doctors in the United States now hold laughter clinics ,in which they help to improve their patients’ condition by encouraging them to laugh .They have found that even if their patients do not really feel like laughing ,making them smile is enough to produce beneficial effects similar to those caused by laughter .
【小题1】Doctors have proved the following EXCEPT that      .

  Remember how great exercise was when you were a little kid? Back then, racing around the playground or skipping rope for hours, you weren’t thinking fitness, you were thinking entertainment. But in this age of high-tech home equipment and underused gym memberships, the simple joy of jumping rope has been forgotten. Rediscovering it will give you a total-body exercise you can find.
Although considered an excellent form of exercise, jumping rope has never gained widespread acceptance because of two fundamental reasons. First, most people recognize jumping rope as an excellent form of cardiovascular (心血管的) exercise, but they also believe that it is simply too difficult. In other words, they don’t think they’ll be able to continue jumping for the near 20 minutes that it takes to achieve a beneficial physical outcome. Second, many view it as somewhat boring and overly repetitive—not as something fun or enjoyable.
As a matter of fact, jumping rope can be great fun if you find a proper way to practice it. Instead of doing the usual two-foot bounce over and over again, people good at rope-jumping often change their pattern every 10 or 20 jumps. A single bounce, a double–bounce, a skip, a knee-up, side swings, as well as a variety of other easy-to-learn free-style rope-jumping.
Now researchers are learning that jumping rope also prepares the brain for learning. It is an exercise allowing both brain hemispheres to perform in parallel to each other. In short , jumping rope can be a life-long activity requiring little equipment, time and space, yet leading to a much healthier life.

Let's do some sleep math. You lost two hours of sleep every night last week because of a big project due on Friday. On Saturday and Sunday, you slept in, getting four extra hours. On Monday morning, you were feeling so bright-eyed, and you only had one cup of coffee, instead of your usual two. But don't be cheated by your energy: You're still carrying around a heavy load of sleepiness, or what experts call " sleep debt "win this case something like six hours, almost a full night's sleep.
Sleep debt is the difference between the amount of sleep you should be getting and the amount you actually get. It's a deficit (赤字)that grows every time we skim some extra minutes off our nightly sleep. "People accumulate sleep debt gradually without being noticed," says psychiatrist William C. Dement, founder of the Stanford University Sleep Research Centre. Studies show that such short-term lack of sleep
leads to a foggy brain, worsened vision, and trouble remembering. Long-term effects include obesity, insulin(胰岛素) resistance, and heart disease. A survey by the National Sleep Foundation reports that we're losing one hour of sleep each night —more than two full weeks of sleep each year.
The good news is that, like all debt, with some work, sleep debt can be repaid. Adding an extra hour or two of sleep a night is the way to catch up. For the long-term lack of sleep, take it easy for a few months to get back into a natural sleep pattern. Go to bed when you are tired, and allow your body to wake you in the morning (no alarm clock allowed). You may find yourself catatonic (有紧张感的)in the beginning of the recovery cycle: Expect to have ten hours' shut-eye per night. As the days pass, however, the amount of sleeping time will gradually decrease.
So earn back that lost sleep —and follow the orders of your inner sleep needs, and you'll feel better. "When you put away sleep debt, you become superman." Says Stanford's Dement, talking about the improved mental and physical capabilities that come with being well rested.
