Exercise is one of the few factors with a positive role in long-term control of body weight. Unfortunately, that message has not gotten through to the average American, who would rather try switching to "light" beer and low-calorie bread than increase physical efforts. The Centers for Disease Control, for example, found that fewer than one-fourth of overweight adults who were trying to lose weight said they were combining exercise with their diet.

?? ????????????? In rejecting exercise, some people may be discouraged too much by caloric-expenditure(熱量消耗)charts; for example, one would have to quickly walk hard three miles just to work off the 275 calories in one delicious Danish pastry(小甜餅). Even exercise professionals accept half a point here. "Exercise by itself is a very tough way to lose weight," says York Onnen, program director of the President's Council on Physical Fitness and Sports.

? ????????????? Still, exercise's supporting role in weight reduction is vital. A study at the Boston University Medical Center of overweight police officers and other public employees confirmed that those who dieted without exercise regained almost all their old weight, while those who worked exercise into their daily routine maintained their new weight.

If you have been sedentary (極少活動的) and decide to start walking one mile a day, the added exercise could burn an extra 100 calories daily. In a year's time, assuming no increase in food intake, you could lose ten pounds. By increasing the distance of your walks gradually and making other dietary adjustments, you may lose even more weight.

A. They tend to hate "light" beer and low-calorie bread.

B. They usually ignore the effect of exercise on losing weight.

C. Most of them were combining exercise with their diet.

A. Controlling one's calorie intake is more important than doing exercise.

B. Even occasional exercise can help reduce weight.

It’s 5:00 in the morning when the alarm (鬧鐘) rings in my ears. I roll out of bed and walk blindly through the dark into the bathroom. I turn on the light and put on my glasses. The house is still as I walk downstairs while my husband and three kids sleep peacefully. Usually I go for a long run, but today I choose my favorite exercise DVD, Insanity. Sweat pours down my face and into my eyes. My heart races as I face my body to finish each movement. As I near the end of the exercise ,I feel extremely tired, but a smile is of my face. It’s a smile because the DVD is over , but a smile of success from pushing my body to its extreme limit.
Some people enjoy shopping, smoking , food, work, or even chocolate. But I need exercise to get through each day. Some shake heads when they see me run through the town. Others get hurt when I refuse to try just one bite of their grandmother’s chocolate cake. They raise their eyebrows, surprised by my “no thank you,” or by my choice to have a salad. Over the years , I have learned it’s okay to just say “no.” I shouldn’t feel sorry for refusing food that I don’t want to eat.
So what drives me to roll out of bed at 5:00 a.m.? What gives me the reason to just say no to ice cream? Commitment. A commitment to change my life with a way that reduces daily anxiety, increases self –confidence and energy, extends life and above all improves my body shape. This is the point where a smile appears on my face as I look at myself in the mirror or try on my favorite pair of jeans that now fit just right. It’s through commitment and sweat that I can make a difference within myself inside and out.

  1.     If you use it often and in the right ways, you will become a more skilled thinker and your ability to focus will increase. But if you never use your brain, or abuse it with harmful chemicals, your ability to think and learn will decrease. Here are some simple ways that may help you.

    2.    

Don’t you feel drained(勞累) after a couple of hours of watching TV? Your eyes are sore and tired of being focused on the light box for so long. When you feel like relaxing, try reading a book instead. If you’re too tired, listen to some music. When you’re with your friends or family, leave the tube off and have a conversation. All of these things use your mind more than television and allow you to relax.

Exercise.

I used to think that I’d learn more by not exercising and using the time to read a book instead.     3.     It improves productivity(生產(chǎn)力) during the time afterwards. Using your body clears your head and creates a wave of energy. Afterwards, you can concentrate(專注) more easily.

Read challenging books.

If you want to improve your thinking and writing ability, you should read books that make you focus. Reading a classic novel can change your view of the world and will make you think in more elegant English.    4.     Re-read it when necessary, and you’ll soon grow accustomed(習(xí)慣) to the author’s style.

Early to bed, early to rise.

     5.     You’ll be the most energetic if you go to bed early and don’t sleep for more than 8 hours. In my experience the early morning hours are the most productive. If you have the opportunity, take a 10-20 minute nap(小憩) when you are hit with a wave of drowsiness(睡意).

A. Take a time to reflect.

B. Reduce television watching.

C. Spending some time alone will be helpful.

D. Your brain needs exercise just like a muscle (肌肉).

E. Don’t be afraid to look up a word if you don’t know it.

F. Nothing makes it harder to concentrate than sleep loss.

G. But I realized that time spent exercising always leads to greater learning.

III. 閱讀理解

閱讀下列短文,從每題所給的A、B、C、D選項中,選出最佳選項。

I’ve written 14 movies. My characters smoke in many of them, and they look cool and glamorous doing it. Smoking was an integral(必需的) part of many of my screenplays because I was a heavy smoker. It was part of a bad-boy image I’d cultivated for a long time— smoking, drinking, partying, rock ’n’ roll.

Smoking, I once believed, was every person’s right. The second-hand smoke was non-existent problem invented by professional do-gooders. I put all these views into my plays.

Remembering all this, I find it hard to forgive myself. I have been an accomplice (幫兇) to the murders of untold numbers of human beings. I am admitting this only because I have made a deal with God. Spare me, I said, and I will try to stop others from committing the same crimes I did.

Eighteen months ago I was diagnosed with throat cancer, the result of a lifetime of smoking. I am alive but disabled. Much of my larynx (喉) is gone. I have some difficulty speaking; others have some difficulty understanding me.

I haven’t smoked or drunk for 18 months now, though I still take it day by day and pray for help. I believe in prayer and exercise. I have walked five miles a day for a year, without missing even one day. Quitting smoking and drinking has taught me the hardest lesson I’ve ever learned about my own weakness; it has also given me the greatest affection and empathy(同感) for those still addicted.

I don’t think smoking is every person’s right anymore. I think smoking should be as illegal as heroin. I’m no longer such a bad boy. I go to church on Sunday. I’m desperate to see my four boys grow up. I want to do everything I can to undo the damage I have done with my own big-screen words and images.

Screen writers know, too, that some movie stars are more likely to play a part if they can smoke —because they are so addicted to smoking that they have difficulty stopping even during the shooting of a scene.

My hands are bloody; so are Hollywood’s. My cancer has caused me to attempt to cleanse me. I don’t wish my fate upon anyone in Hollywood, but I beg that Hollywood should stop putting it upon millions of others.

1. The main idea of this passage probably is _________.

A. the writer is ashamed of the bad effects his screenplays have had on human beings

B. the writer’s smoking experience nearly killed himself

C. the bad effects that Hollywood screenplay have brought to children

D. the determination of the writer to overcome his illness

A. So many people have found the habit of smoking due to his plays.

B. His plays have brought great harm to teenagers.

C. He himself suffered greatly from smoking.

D. His screenplays have been doing more and more harm to human beings.

3. What is the writer determined to do in future?

A. He has made up his mind to give up smoking forever.

B. He will try his best to prevent others from writing screen plays encouraging smoking.

C. He will try his best to bring up his four children.

D. He has decided to write his screenplays without smoking scenes.

4. It can be inferred from the passage that _______.

A. the writer will soon be recovered from his illness thanks to his exercise

B. the writer will soon die because of his deadly disease

C. smoking will be got rid of in all Hollywood films

D. smoking in Hollywood films is still doing great harm to human beings
