The Internet has opened up a whole new online world for us to meet, chat and go where we've never been before.

    But just as in face to face communication, there are some rules of behavior that should be followed when on line. {#blank#}1{#/blank#} Imagine how you'd feel if you were in the other person's shoes.

    For anything you're about to send: ask yourself, “Would I say this to the person's face? If the answer is no, rewrite and reread. {#blank#}2{#/blank#}

    If someone in the chat room is rude to you, your instinct (本能 ) is to fire back in the same manner. But try not to do so. {#blank#}3{#/blank#} If it was caused by a disagreement with another member, try to fix the situation by politely discussing it. Remember to respect opinions of others in the chat room.

    {#blank#}4{#/blank#} Offer advice when asked by newcomers, as they may not be sure what to do or how to communicate. When someone makes a mistake, whether it's a stupid question or an unnecessarily long answer, be kind about it. If it is a small mistake, you may not need to say anything. Having good manners yourself doesn't give you license to correct everyone else. {#blank#}5{#/blank#} At the same time, if you find you are wrong, be sure to correct yourself and apologize to those you have offended.

    I used to be a thin little kid who was always the shortest and sickest in my class. I wasn't very athletically involved during my childhood.

    When I entered middle school, a lot of my friends were signing up for the school's sports teams. {#blank#}1{#/blank#}On the first day of tryouts(选拔赛) for the soccer team, the coach told us to run laps for warm-up. As I struggled to keep up with the team, I found myself falling farther behind until I was the last one to finish. {#blank#}2{#/blank#}

    I was disappointed, but at the same time, I knew I had to do something about my health and fitness. {#blank#}3{#/blank#} People thought I was crazy because I ran a slow 11-mintue mile in the gym class, but I was determined to get into shape and improve my mile time.

    {#blank#}4{#/blank#} It was a lot of running for me, but I kept on practicing day after day. As the seasons progressed, I found that I could run longer and faster.

    Eighth grade soon rolled around and I was feeling really confident about trying out for another sports meet. Instead of attempting soccer a second time, I decided to give field hockey a try. {#blank#}5{#/blank#} This time, I was well prepared. After a week of tryouts, I was ecstatic (狂喜的) to see that my name made it on the list.

    I was inspired, and I learned an important lesson: Once you do get into shape, don't stop or give up!

A. Again, the coach instructed us to run a lot of laps.

B. After tryouts were over, my name never made it on the list.

C. I made a big decision to sign up for the track and field team.

D. Being in shape helped me feel energetic, flexible, and strong.

E. Fortunately, I wasn't the only slow runner trying to get into shape.

F. The first day of practice was one of the hardest workouts I've ever had.

G. One of my friends convinced me to try out for the soccer team with her and I agreed.

    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.

    Reading is really a good way to improve ourselves.{#blank#}1{#/blank#} If you don't believe me, please consider these reasons to read more books.

    ⒈You will optimize your brain power.

    {#blank#}2{#/blank#} Unlike watching television, which requires no thought process, reading is an active learning experience that will keep your mind sharp（even in old age）.

    ⒉{#blank#}3{#/blank#}

    If you're looking for entertainment on a budget, you can't beat books. Thanks to the popularity of electronic reading devices like the Kindle and re-selling websites like eBay, it's never been easier to entertain yourself for hours at a time, for the low cost of a few dollars.

    ⒊You will reduce stress and get into a good night's sleep.

    Exposing yourself to artificial light on your cellphone or TV reduces your body's production of melatonin （褪黑激素）, which can make it difficult to get a good night's sleep.{#blank#}4{#/blank#} Just replace that with a good book, which is a much better sleep-friendly alternative.

    ⒋You will change your life.

    I firmly believe that if it were not for books, I wouldn't have achieved so much in my life; nor would I have the knowledge, imagination or creativity that I depend on as a writer, business owner, and coach.

    Do you have the desire to read books now?{#blank#}5{#/blank#}

A. You will entertain yourself at any time.

B. You will entertain yourself at a low price.

C. The more books you read, the better your life will be.

D. This shouldn't come as a shock, but studies suggest reading makes you smart.

E. I hope these reasons encourage you to unlock your potential with the power of reading.

F. You should know that it is wise to keep a book in your purse or car at all times.

G. You would be wise to cut off all electronics at least an hour before bed.

How old is “old”?

    How old is “old”? {#blank#}1{#/blank#}Two hundred years ago, you were old at 35. That was the average life then. At the turn of this century, as medical knowledge advanced, the average life span(长度) increased to 45. In 1950, 70-year-olds were really old. Today, a healthy 70-year-old is looking forward to many more active years.

    So, how old is old? The answer is one you've heard many times, from all sorts of people. “You are as old (or young) as you feel!” The calendar(日历) simply tells you how many years you have lived. {#blank#}2{#/blank#}

    Once an unknown author wrote,“ {#blank#}3{#/blank#}Nobody grows old by living a number of years; people grow old by giving up their goals.”

    {#blank#}4{#/blank#}Alice Brophy, when she was with the New York City commission for the Aging, said, “It upsets me when people say, 'Gee, you look young for your age!' What does that mean? Is there some model that you're supposed to look a certain way at 65 and 75 and 85? You know you can die old at 30 and live young at 80.”

There are many wrong ideas about aging. {#blank#}5{#/blank#}Here are some of the more common ones. For example, most older people are in poor health, or older people are unable to change.

A. Old is a point of view.

B. It's extremely terrible to be grown old.

C. The answer has changed over the years.

D. Your body tells you how well you've lived.

E. Older people are stubborn, unable to change.

F. Youth is not a time of life but it is a state of mind.

G. These ideas stereotype (固化) people on the basis of age.

Everyone can help to save the world

    We are all environmentalists now. We all know about acid rain and the ozone hole. {#blank#}1{#/blank#} As consumers we have the power to make decisions which will contribute to a better world and it is in our power to do what we can to protect the earth.  

    {#blank#}2{#/blank#} In this way we have the power to influence retailers (零售商) to sell us those so-called "green" products. Therefore, the supermarkets have understood the message and are now trying to improve their environmental image. They are turning to less wasteful and recyclable packaging. The range of "green" products will continue to expand to meet the growing demand. This message has also reached the manufacturers. {#blank#}3{#/blank#}They have realized that protecting the environment may start as an advertising campaign but in the hands of intelligent people it can become a very profitable business. Besides, we can do more.

    Furthermore, we also know there are other areas where all of us can make a positive contribution to a cleaner, healthier and safer environment. {#blank#}4{#/blank#}There are a number of ways we can do this. For example, we now know how important it is to have our homes well insulated (隔热). We should choose the best energy efficient technology, such as modern light bulbs which can reduce electricity consumption by 80% over the older ones. We must also work hard to reduce the amount of rubbish we produce. We all produce tons of rubbish and waste disposal has become a big problem. As an environmentally-conscious consumer we should buy products which do not have so much packaging. Also, we should try to avoid non-returnable goods at all costs. In Scandinavia and Germany, for example, plastic bottles and cans are now returnable goods.  

    In conclusion it is important to emphasize once again the rise of consumer power. We must realize that we are all part of the problem. {#blank#}5{#/blank#} 

A. We can all reduce energy consumption at home and so cut the emissions from power systems.

B. For example, when we walk into a supermarket we can choose to buy environmentally friendly products and reject products which damage our planet.

C. There are some other ways to protect the environment.

D. Companies are developing environmentally friendly products that maintain a high quality and a low price.

E. But what are we doing about these problems?

F. Nevertheless we must also realize that we have the responsibility to be part of the solution.

G. Everybody has the duty to contribute to a cleaner world.
