Eyesight（视力) plays a very important role in our daily life. Every waking moment, the eyes are working to see the world around us. Over forty percent of Americans worry about losing eyesight, but it's easy to include steps into our daily life to ensure healthy eyes. Here are five suggestions for a lifetime of healthy eyesight：

    Schedule（安排）yearly exams(检查). {#blank#}1{#/blank#} Experts advise parents to bring babies 6 to 12 months of age to the doctor for a careful check. The good news is that millions of children now can have yearly eye exams and following treatment, including eyeglasses.

    Protect against UV rays (紫外线). Long-term stay in the sun creates risk to your eyes. No matter what the season is, it's extremely important to wear sunglasses. {#blank#}2{#/blank#}

    Give your eyes a break. Two-thirds of Americans spend up to seven hours a day using computers or other digital products. {#blank#}3{#/blank#} Experts recommend that people practice the 20/20/20 rule: every 20 minutes, take a 20-second break and look at something 20 feet away.

    {#blank#}4{#/blank#} As part of a healthy diet, eat more fruits and vegetables each day. Vitamins (维生素) C and E help protect eyesight and promote eye health.

    Practice safe wear and care of contact lenses (隐形眼镜). Many Americans use contact lenses to improve their eyesight. While some follow the medical guidance for wearing contact lenses, many are breaking the rules and putting their eyesight at risk. {#blank#}5{#/blank#} Otherwise, you may have problems such as red eyes, pain in the eyes, or a more serious condition.

A．Eat your greens.

B．Eye care should begin early in life.

C．They can properly protect your eyes.

D．Stay in good shape by taking more vitamins.

E．Parents usually don't care about their own eyesight.

F．Always follow the doctor's advice for appropriate（适当的）wear.

G．This frequent eye activity increases the risk for eye tiredness.

    Recently some American scientists have a useful piece of advice to people in industrialized nations. They say people should eat more of the same kind of food eaten by humans living more than 10, 000 years ago.{#blank#}1{#/blank#}

    The scientists say that the human life has changed greatly. Our bodies have not been able to deal with these changes in lifestyle and this has led to new kinds of sicknesses. These new sicknesses were not known in ancient times.So they are called “diseases of civilization”. {#blank#}2{#/blank#}

    Scientists noted that people in both the Old Stone Age and the New Stone Age enjoyed very little alcohol or tobacco, probably none.{#blank#}3{#/blank#} However, a change in food is one of the main differences between life in ancient times and that of today.

    Stone Age people hunted wild animals for their meat, which had much less fat than domestic ones. They ate a lot of fresh wild vegetables and fruits. They did not have milk or any other dairy products, and they made very little use of grains.{#blank#}4{#/blank#}We eat six times more salt than our ancestors. We eat more sugar. We eat twice as much fat but only one third as much protein and much less vitamin C.

    {#blank#}5{#/blank#}But scientists say that we would be much healthier if we eat much the same way the ancient people did, cutting the amount of fatty, salty and sweet food.

    Sleep and Teens--Biology and Behavior

    How much sleep do teens need? And how much sleep are they realistically getting? Based on current data, most teens need about 9-plus hours to have the best or most suitable sleep night{#blank#}1{#/blank#}

    Many factors combine to decrease sleep in adolescents. We can think in general of two major factors: biological, the brain processes that regulate the amount and timing of sleep, and behavior, all the psychological, parental, societal, cultural features of teen's life.

    {#blank#}2{#/blank#}These changes lay the ground work for the biological night to occur later during the teen years than before. Circadian Rhythms (daily biological clock) seems to slow down as young people progress through the middle school years. At the same time, the sleep pressure system appears to change in a way that makes it easier to stay awake longer, though without changing the amount of sleep that is needed.

    Moreover, many teens have a "technological playground" in their bedrooms: television, computer with 24/7 Internet access, telephones, electronic game stations, MP3 players, and so forth. These technologies provide instant and constant contact with peers. Societal and media pressure to consume these technologies is now higher than ever. Yet society also requires that teens go to school at a time of day that is at odds with their biological and social lives. So we see teens turn to caffeine, late-night Internet and cramming in activity after activity as a means to keep awake.{#blank#}3{#/blank#}

    Problems emerge for lack of sleep{#blank#}4{#/blank#}For some, grades begin to suffer as they struggle to keep awake during class and while doing homework. And others may simply feel moody, never knowing how to feel or do their best. Worse still, many teens suffer from both physical and mental illness.

    {#blank#}5{#/blank#}The earlier teens can start this good sleep habit, the easier it will be for them to stay healthy, happy and smart.

A. Sleep experts recommend teens keep consistent sleep and wake schedule

B. Teens may schedule sleep like any other daily activity and make sleep a priority

C. Then they are trapped into a terrible situation where they would never get enough sleep

D. The sleep-wake bio-regulatory factors appear to change significantly during adolescence

E. Some teenagers struggle to wake up in the morning, often resulting in late or missed school

F. Teens may be driven to things that can wake them up because they'll fall asleep if they do not

G. However, it is indicated that most teens fall short of this goal, many by a considerable amount.

    Humor plays an important role in relationships. In new relationships, humor can be an effective tool not just for attracting the other person but also for overcoming any awkwardness or embarrassment.{#blank#}1{#/blank#}

Sharing the pleasure of humor creates a sense of connection between two people. When you laugh with one another, you create a positive tie between you. This tie acts as a strong buffer(缓冲) against stress, disagreements, disappointments, and bad patches in a relationship. And laughter really is infectious.{#blank#}2{#/blank#} But don't worry if you're not naturally a lighthearted, humorous person—you can learn to access your playful side and develop your sense of fun.

    Like any tool, humor can be used in negative as well as positive ways. Humor can only help you overcome relationship problems when both partners can understand the joke.{#blank#}3{#/blank#} If your partner or friend isn't likely to appreciate the joke, don't say or do it. Humor in relationships should be equally fun and enjoyable for both people.

Don't use humor to cover up other emotions.{#blank#}4{#/blank#} That's when it is used as a cover for avoiding, rather than coping with, painful emotions. You can be funny about the truth, but covering up the truth isn't funny. When you use humor and playfulness as a cover for other emotions, you create confusion and mistrust in your relationships.

    {#blank#}5{#/blank#} The important thing is to find enjoyable activities that help you embrace your playful nature with other people. As humor and play become an unseparated part of your life, you'll begin to find daily opportunities for using your new-found skills to help build and maintain your relationships.

A. Humor can help you and your loved one.

B. There are times when humor is not healthy.

C. It's important to be sensitive to the other person.

D. It's never too late to develop your humorous side.

E. The more you joke, play, and laugh—the easier it becomes.

F. Just hearing someone laugh can make you smile and join in on the fun.

G. In longer-term relationships, humor can keep things exciting and fresh.

    Everyone makes mistakes.{#blank#}1{#/blank#}. Making a mistake at work, however, can be more serious. It may cause problems for your employer and even affect the company's bottom line Evil consequences will finally come down to you. Simply correcting your mistake and moving on may not be an option. When you make a mistake at work your career may depend on what you do next.

    Admit your mistake.

    Tell your boss about your mistake immediately. The only exception is if you make an insignificant error that will not affect anyone. Otherwise, don't try to hide your mistake.{#blank#}2{#/blank#}.

    Present your boss with a plan to fix your mistake.

    When you go to your boss to admit your mistake, you must have a plan for correcting it. Present your plan clearly. Tell your boss how long it will take to carry out your plan and if there are any costs involved.

    Don't blame anyone else for your mistake.

    {#blank#}3{#/blank#}. Encourage those who may share responsibility to follow your lead in admitting to your boss.

    {#blank#}4{#/blank#}.

    There's a big difference between admitting your mistake and beating yourself up about it. Take responsibility but don't blame yourself for making it, especially in public.

    Correct your mistake on your own time.

    If you have to spend extra hours at work to correct your mistake, don't expect to be paid for that time.{#blank#}5{#/blank#}.

A. Apologize for your mistake but don't beat yourself up

B. Usually you can correct your error or just forget about it and move on

C. You can use your lunch hour or come into work early

D. Pointing fingers at others won't help you if you make a mistake

E. Strengthen your friendship with your boss

F. You'll feel ashamed if your colleague takes the responsibility for you

G. You will look terrible if someone else discovers it

Spreading smiles at Birchwood

    When Ava McCarver was in kindergarten, her class visited a nursing home (疗养院). Ava learned that many of the residents (住户) there receive few visitors. {#blank#}1{#/blank#}"I asked my mom if I could visit them," she says. Soon, Ava and her mom became volunteers at Birchwood Health Care Center.

    That was six years ago. {#blank#}2{#/blank#}She enjoys hanging out with Mary, Shirley and other residents during her twice-monthly visits. "I paint their nails, and I talk to a lot of them," she says. Sometimes she helps lead craft (手工艺) projects. Other times they play card games. "It's good for the residents to see little kids," Ava says. "That makes them really happy."

    {#blank#}3{#/blank#}She has raised money for the nursing home by making refrigerator decorations and selling them at a craft fair. She has also collected used puzzles from garage sales and donated them to Birchwood.

    Ava wrote a book called The Squirrel Family. In the book, two squirrels raise a family and eventually move into a place called Birchwood where they live happily. {#blank#}4{#/blank#}Ten stores in her city agreed to display the books, along with a can to collect money. Ava's project raised about $750. Birchwood used that money to buy furniture for the residents.

    Ava says she enjoyed the look of "pure joy" on a resident's face after a hug from her. That's why she started visiting Birchwood — to bring happiness to others.{#blank#}5{#/blank#}"It's really fun," she says. "They have good stories, and I enjoy my time there."
