“Everything happens for the best.” Whenever I faced disappointment(失望),my mother would say this to me.

After I left college in 1932, I decided to find a job in radio as a sports announcer(廣播員). I went to Chicago and knocked at the door of every station. But unluckily, I was refused every time.

At one station, a kind lady told me that big stations wouldn’t hire(雇傭) a person without any experience and suggested that I try my luck at smaller stations. Following her advice, I went back to Dixon, where I had grown up. There were no such jobs in Dixon, and my father said a newly-opened store wanted a local athlete(運(yùn)動員)to work for it. I wanted this job, but I was refused again.

“Everything happens for the best,” Mom reminded me. Dad offered me the car to look for a job. I tried WOC Radio in Davenport, Iowa. The program director, Peter MacArthur, told me they had already hired an announcer.

As I left his office, I felt so frustrated(沮喪). “How can I become a sports announcer if I can’t get a job in a radio station?” I asked aloud.

While I was waiting for the lift, I heard someone calling. It was MacArthur. “What was that you said about sports? Do you know anything about football?” Then he asked me to have a try. He was pleased with my performance, and he offered me a chance to work there.

On my way home, I thought of my mother’s words: “If you carry on, one day something good will happen. Something wouldn’t have happened if without the failure before.”

Saying no starts small

“All right then — just one more piece...” Words every girl has said when they are faced with the delicious cheesecake. Of course, many of us know we may eat the whole thing in the end.

It isn’t just girls. Most of us find it hard to say “no” to something attractive. However, scientists now say that willpower is very important to success and a happy life.

Scientists in different countries have been studying the effects of willpower on people’s lives for a long time. The results are similar, according to an article on February 7 in the Guardian, a famous British newspaper.

In one experiment, scientists told young children that they could either have a marshmallow (圓形軟糖) now, or two marshmallows in 15 minutes. Waiting obviously needed more willpower. Scientists then continued studying the children as they grew up. They wanted to see if some children always had stronger willpower. They also wanted to see how having stronger willpower affected their lives.

Years later, scientists found that the children who had waited for two marshmallows were all healthier, happier and richer adults. Oppositely, the children who had shown weaker willpower at that young age were more likely to be in low-paid jobs, to be overweight, to have social problems.

But there is hope, Roy F Baumeister, an American social psychology(心理學(xué)) professor (教授) told the Guardian. Baumeister says we can train our willpower just like we train our muscles（肌肉）. Even a little practice can strengthen（加強(qiáng)） our overall self-control if we do it regularly.

You could start by making yourself stand up straight, speaking in complete sentences, or using a computer mouse with the other hand. Scientists have found that people who manage to change little habits often perform much better in laboratory willpower tests.

Like muscles, willpower can “get tired”. Don’t try to do too many things at the same time, or when you don’t have enough energy, for example when you are ill. If you already feel tired, you can try to recharge(恢復(fù)) your willpower with a good night’s sleep and by eating well.

1.The example of a girl eating cheesecake is used to

A. prove that girls have weak willpower

B. introduce the topic of willpower to the readers

C. show that cheesecake is especially attractive to girls

D. show the connection between willpower and success

2.What can we infer from the experiment?

A. The scientists had already known the results before the experiment.

B. It showed that willpower is the most important to success and a happy life.

C. The children who chose to wait were more likely to be successful in their lives.

D. The children who chose only one marshmallow at first had stronger willpower.

3.Which of the following is NOT mentioned about the training of willpower?

A. You should have a goal every day.

B. Good rest and proper diet can help.

C. Willpower needs to be exercised regularly.

D. Keep willpower from being used too much.

4.What is the article mainly about?

A. How willpower and muscles are similar and how they can be trained.

B. How willpower affects people’s lives and how it is similar to muscles.

C. How willpower is important to success and how we can make it stronger.

D. How willpower is connected with success and how they affect each other
