    　　Sweet potatoes are fat-free, high in fiber and full of the vitamins that research suggests reduce your risk of life-shortening diseases. To stay healthy, we must eat more fruits and vegetables, and sweet potatoes are a great source of beta carotene (胡罗卜素) and other carotenoids. According to a study of the diets of almost 90,000 nurses, eating about one cup a day of fruits and vegetables rich in carotenoids (which the body turns into vitamin A) can cut your risk of stroke in half and reduce your risk of heart disease by 22 percent. Other research suggests beta carotene protects against breast, lung and stomach cancers.

    Beta carotene is the most famous member of the carotenoids family. In fact, a medium-sized sweet potato contains nearly 12 mg of beta carotene (anti-aging experts usually suggest 6 to 11 mg per day ). Sweet potatoes are also a low-fat source of vitamin E. Research has linked high E diets with a lower risk of heart disease. This vitamin pill in an orange jacket also packs a vitamin C punch-it has more C than apricots (a kind of fruit ). Researh suggests that vitamin C protects against ailments ranging from cataracts (an eye disease) to cancer. In addition, a UCLA (University of California Los Angeles ) study linked high vitamin C diets with a longer life. Recent studies have showed that antioxidant vitamins C, E and beta carotene fight a fierce battle against free radicals (自由基), which cause cell (细胞) damage and lead to various

    illnesses. Therefore, to keep fit, eat more sweet potatoes.

    　　Odland remembers like it was yesterday working in an expensive French restaurant in Denver．The ice cream he was serving fell onto the white dress of a rich and important woman．

    　　Thirty years have passed, but Odland can't get the memory out of his mind, nor the woman's kind reaction．She was shocked, regained calmness and, in a kind voice, told the young Odland,“It's OK．It wasn't your fault．”When she left the restaurant, she also left the future Fortune 500 CEO with a life lesson：You can tell a lot about a person by the way he or she treats the waiter．

    　　Odland isn't the only CEO to have made this discovery．Rather, it seems to be one of those few laws of the land that every CEO learns on the way up．It's hard to get a dozen CEO's to agree about anything, but most agree with the Waiter Rule．They say how others treat the CEO says nothing．But how others treat the waiter is like a window into the soul．

    　　Watch out for anyone who pulls out the power card to say something like,“I could but this place and fire you,”or“I know the owner and I could have you fired．”Those who say such things have shown more about their character than about their wealth and power．

    　　The CEO who came up with it, or at least first wrote it down, is Raytheon CEO Bill Swanson．He wrote a best-selling book called Swanson's Unwritten Rules of Management．

    　　“A person who is nice to you but rude to the waiter, or to others, is not a nice person,”Swanson says．“I will never offer a job to the person who is sweet to the boss but turns rude to someone cleaning the tables．”

    阅读理解。

    　　Years ago, when I started looking for my first job, wise advisers said,“Barbara, be enthusiastic!Enthusiasm will take your further than any amount of experience．”How right they were!

    　　“Nothing great was ever achieved without enthusiasm,”wrote Ralph Waldo Emerson．It is the paste that helps you hang on there when the going gets tough．It is the inner voice that whispers,“I can do it!”when others shout,“No, you can't!”It took years and years for the early work of Barbara McClintock, a geneticist who won the 1983 Nobel Prize in medicine, to be generally accepted．Yet she didn't let up on her experiments．Work was such a deep pressure for her that she never thought of stopping．

    　　We are all born with wide-eyed, enthusiastic wonder and it is this childlike wonder that gives enthusiastic people such youthful air, whatever their age．At 90, cellist(大提琴家)Pablo Casals would start his day by playing Bach(巴赫)．As the music flowed through his fingers, his bend shoulders would strengthen and joy would reappear in his eyes．As author and poet Samuel once wrote,“Yeas make the skin old, but to give up enthusiasm makes the soul old．”

    　　Enthusiastic people also love what they do, regardless of money, title or power．Patricia Mcllrath, retired director of the Missouri Repertory Theater in Kansas City, was once asked where she got her enthusiasm．She replied, “My father, a lawyer, long ago told me, I never made a penny until I stopped working for money．”

    　　If we can't do what we love as a full-time career, we can do it as a hobby．Elizabeth Layton of Wellsville, Kan, was 68 before she began to draw．This activity ended her sadness that had troubled her for at least 30 years, and the quality of her work led one critic(评论家)to say,“I am persuaded to call Layton a genius．”

    　　We can't afford to waste tears on“might-have-beens”．We need to turn the tears into sweat as we go after“what-can-be”．We need to live each moment whole-heartedly, with all our senses－finding pleasure in the sweet smell of a backyard garden, the simple picture of a six-year-old, and the beauty of a rainbow．

    (1)

    The passage mainly shows us ________．

    [　　]

    A．

    enthusiasm is the basic element of everything

    B．

    enthusiasm helps us to succeed to a greater degree

    C．

    enthusiasm makes us experience more life

    D．

    we can do nothing without enthusiasm

    (2)

    From the example of the Nobel Prize winner Barbara McClintock, we may find ________．

    [　　]

    A．

    enthusiasm can encourage us in difficult times

    B．

    enthusiastic people always get a deep pleasure from work

    C．

    you can't make any achievement if you have no enthusiasm

    D．

    enthusiastic people are sure to gain great fame in the end

    (3)

    The underlined sentence in Paragraph Three suggests ________．

    [　　]

    A．

    time and tide wait for no man

    B．

    we grow old as time goes on

    C．

    people feel young with enthusiasm

    D．

    our soul becomes old with enthusiasm

    (4)

    The sentence“I never made a penny until I stopped working for money．”In Paragraph Four refers to“________”．

    [　　]

    A．

    I wouldn't work unless I could make money

    B．

    I believe that my work will be rewarded

    C．

    Working for money is what I love to do

    D．

    Working for money makes no money at all

    (5)

    The main idea of the last paragraph is ________．

    [　　]

    A．

    we should try heart and soul to win what we want

    B．

    enthusiasm can give us pleasure, though we have to sweat

    C．

    we have not enough money to buy what we need

    D．

    Secretary

    　　Jenny loves office work but it's hard on her figure. All those sandwich lunches and her sweet tooth added up to extra pounds till Jenny started slimming(减肥) with Bisks.

    　　Every lunchtime she'd have a Bisks chocolate bar with a glass of milk. It filled her up and satisfied her longing for sweet things. And it was all so convenient.

    　　She watched what she ate at her other meals and soon she was losing weight. Now Jenny's feeling looking so good even her boss notices the difference.

    　　That was her proof that Bisks work.

    Housewife

    　　In a few weeks Sue had lost her extra weight. Now she's even taking a class in cooking!

    　　That's proof that Bisks work.

    阅读理解：

    　　Not all memories are sweet．Some people spend all their lives trying to forget bad experiences．Violence and traffic accidents can leave people with terrible physical and emotional scars．Often they relive these experiences in nightmares．

    　　Now American researchers think they are close to developing a pill, which will help people forget bad memories．The pill is designed to be taken immediately after a frightening experience．They hope it might reduce, or possibly wipe out, the effect of painful memories．

    　　In November, experts tested a drug on people in the US and France．The drug stops the body releasing(释放)chemicals that fix memories in the brain．So far the research has suggested that only the emotional effects of memories may be reduced, not that the memories are wiped out．They are not sure to what degree people's memories are affected．

    　　The research has caused a great deal of argument．Some think it is a bad idea, while others support it．Supporters say it could lead to pills that prevent or treat soldiers' troubling memories after war．They say that there are many people who suffer from terrible memories．

    　　“Some memories can ruin people's lives．They come back to you when you don't want to have them in a daydream or nightmare．They usually come with very painful emotions,”said Roger Pitman, a professor of psychiatry at Harvard Medical School．“This could relieve a lot of that suffering．”

    　　But those who are against the research say that maybe the pills can change people's memories and changing memories is very dangerous because memories give us our identity(特质)．They also help us all avoid the mistakes of the past．

    　　“All of us can think of bad events in our lives that were terrible at the time but make us who we are．I'm not sure we want to wipe those memories out,”said Rebecca Dresser, a medical ethicist．

    (1)

    The drug tested on people can ________．

    [　　]

    B．

    stop people remembering bad experiences

    C．

    prevent body producing certain chemicals

    D．

    wipe out the emotional effects of memories

    A．

    people doubt the effects of the pills

    B．

    the pill will certainly stop people's emotional memories
