No one knows yet the accurate number of ...

America is a country on the move. In unheard of numbers, people of all ages are exercising  their way to better health. According to the latest figures, 59 percent of American adults exercise regularly-up 12 percent from just two years ago and more than double the figure of 25 years ago. Even non-exercisers believe they would be more attractive and confident if they were more active.

It is hard not to get the message. The virtues of physical fitness are shown on magazine covers, postage stamps, and television ads of everything from beauty soaps to travel books. Exercise as a part of daily life did not catch on until the late 1960s when research by military doctors began to show the health benefits of doing regular physical exercises. Growing publicity (宣传) for races held in American cities helped fuel a strong interest in the ancient sport of running. Although running has leveled off in recent years as Americans have discovered equally rewarding—and sometimes safer-forms of exercise, such as walking and swimming, running remains the most popular form of exercise.

As the popularity of exercise continues to mount, so does scientific evidence of its health benefits. The key to fitness is exercising the major muscle groups vigorously (强有力地) enough to approximately double the heart rate and keep it doubled for 20 to 30 minutes at a time. Doing such physical exercises three times or more a week will produce considerable improvements in physical health in about three months.

1.It can be learnt from the passage that the health benefits of exercise ___________.

2.A growing interest in sports developed after ______________.

3.Which of the following would be the best title for the passage?

4.Which of the following is closest in meaning to the phrase “leveled off” in the paragraph 2?

I know what you're thinking: pizza? For breakfast? But the truth is that you can have last night's leftovers in the a. m. if you want to.

I know lots of women who skip breakfast, and they have a ton of different excuses for doing it. Some say they don't have time, others think they're “saving” calories, still others just don't like breakfast food.

But the bottom line is that eating in the morning is very important when you’re trying to lose weight. “Eating just about anything from 300 to 400 calories would be better than nothing at all,” says Katherine Brooking, R, D, who developed the super-easy eating plan for this year’s “SELF CHALLENGE”. And even pizza can be healthy if it's loaded with vegetables, and you stick to one small piece.

Breakfast is one meal I never miss, and the same goes for most weight loss success stories. Research shows that eating breakfast keeps you from overeating later in the day. Researchers at the University of Southern California found that breakfast skippers have a bigger chance of gaining weight than those who regularly have a morning meal.

So eat something in the morning, anything. I know plenty of friends who end up having no breakfast altogether, and have just coffee or orange juice. I say, try heating up last night’s leftovers－it may sound crazy, but if it works for you, do it! I find if I tell myself, “You can always eat it tomorrow,” I put away the leftovers instead of eating more that night. Try it... you may save yourself some pre­bedtime calories. And watch your body gain the fat­burning effects.

1.The underlined word "leftovers" in Paragraph 1 probably means ______.

2.What can we infer from the text?

3.According to the last paragraph, it is important to ______.

4.The text is written mainly for those _______.

“Everything happens for the best,” my mother said whenever I   36 disappointment. “If you can carry on, one day something   37 will happen. And you’ll realize that it wouldn’t have happened if not for that   38 disappointment.”

Mother was right,   39 I discovered after graduating from college in 1932. I had decided to   40 a job in radio, then work my way up to sports   41 . I hitchhiked（搭便车） to Chicago and   42 on the door of every station—and got turned   43 every time.

In one studio, a kind lady told me that big stations couldn’t risk hiring an   44 person –“Go out in the sticks（偏远地区） and find a small station that will give you a   45 ,” she said.

I thumbed home to Dixon, Illinois.   46 there was no radio—announcing job in Dixon, my father said Montgomery Ward had opened a store and wanted a local athlete to   47 its sports department. Since Dixon was where I had played high school football. I   48 . The job   49 just right for me. But I wasn’t hired.

My disappointment must have   50 . “Everything happens for the best,” Mom   51 me. Dad offered me the car to job hunt. I tried WOC Radio in Davenport, Iowa. The program director, a wonderful Scotsman named Peter MacArthur, told me they had already hired an announcer.

As I left his office, my frustration   52 . I asked aloud, “How can a fellow get to be a sport announcer if he can’t get a job in a radio station?”

I was waiting for the elevator   53 I heard MacAethur calling, “What was that you said about sports? Do you know anything about football?” Then he asked me to stand before a microphone and to broadcast a (an)   54 game.

On my way home, once again I thought of my mother’s words. I often wonder what   55 my life might have taken if I’d gotten the job at Montgomery Ward.
