The Healthy Habits Survey(调查)shows that only about one third of American seniors have correct habits. Here are some findings and expert advice.

    1). How many times did you brush your teeth yesterday?

    Finding：A full 33% of seniors brush their teeth only once a day.

    Step：Remove the 300 types of bacteria in your mouth each morning with a battery-operated toothbrush. Brush gently for 2 minutes, at least twice a day.

    2). How many times did you wash your hands or bathe yesterday?

    Finding：Seniors, on average, bathe fewer than 3 days a week. And nearly 30%wash their hands only 4 times a day-half of the number doctors recommend.

    Step：We touch our faces around 3,000 times a day-often inviting germs(病菌)to enter our mouth, nose, and eyes. Use toilet paper to avoid touching the door handle. And, most important, wash your hands often with hot running water and soap for 20 seconds.

    3). How often do you think about fighting germs?

    Finding：Seniors are not fighting germs as well as they should.

    Step：Be aware of germs. Do you know it is not your toilet but your kitchen sponge(海绵)that can carry more germs than anything else? To kill these germs, keep your sponge in the microwave for 10 seconds.

    Winter running is the best way to lose winter weight. But before heading out, make sure you have a solid plan. You don't want to come across accident along the way. {#blank#}1{#/blank#}

    Wear the Right Shoes

    The right shoes will depend on the road. You want shoes that are made for the kind of surface you run on. For example, if you are running on slippery surfaces, you want shoes with great friction(摩擦力). {#blank#}2{#/blank#} When trying out a pair of running shoes, check the fit, feel and ride of the shoes. These elements(要素) are important once you take your new shoes out for a run.

    Warm Up

    Warm up is an important part to keep fit. Especially if temperatures drop and your muscles are stiff(僵硬的) from the cold! {#blank#}3{#/blank#} It also prepares the muscles for the intense (激烈的) activity ahead. The cold climate won't feel as cold when you do warm ups. This is because blood flows much faster after a good warm up!

    Deal with Wind

    {#blank#}4{#/blank#}The key is to run into the wind and finish by running against it. This keeps icy wind from blasting(用力撞击) your face. To prevent any injuries or accidents, break your run into small parts. {#blank#}5{#/blank#} You can use certain creams on the nose and cheeks to prevent frostbite(冻疮).Don't skip your sun-block if you're running during the day. UVB(紫外线)passes through the clouds. Running for an extended period on a cloudy day will still damage the skin!

A．Don't run in the wind.

B．Running makes you warm.

C．Warming up prevents injuries.

D．It's hard to run if it's too windy.

E．Your shoes should fit very well so you don't slip.

    Traveling can be a fun way to gain life experiences, especially during Spring Break-a week-long school vacation in the United States. But what if you're a student and don't have enough money for a trip？Don't worry. Here are some useful suggestions.

    Save：This probably is the most important preparation for traveling. Cut expenses to fatten your wallet so you'll have more choices about where to go and how to get there.

    Plan ahead：Don't wait until the last minute to plan your trip. Tickets may cost more when bought on short notice. Giving yourself several months to get ready can mean security and savings.

    Do your homework：No matter where you go, research the places you will visit. Decide what to see. Travel books will provide information on the cheapest hotels and restaurants.

    Plan sensibly：Write down how much you expect to spend for food and hotels. Stick to your plan or you may not have enough money to cover everything.

    Travel in groups：Find someone who is interested in visiting the same places. By traveling with others you can share costs and experiences.

    Work as you go：Need more money to support your trip？Look for work in the places you visit.

    Go off the beaten path：Tourist sites may be expensive. You may want to rethink your trip and go to a less﹣known area. Smaller towns can have many interesting activities and sights.

    Pack necessary things：The most important things to take are not always clothes.

Remember medicine in case you get sick, and snacks in case you cannot find a cheap restaurant.

    Use the Internet：The net can help to save money. Some useful websites include www.travelcity.corn, www.bargainslowestfare.corn and www.economictravelcity.com.

    By planning sensibly, even students can enjoy the travel. Your travel experiences will be remembered for a lifetime.

    My favourite book is The Adventure of Tom Sawyer by Mark Twain. Tom lives with his aunt Polly in a quiet street of St. Petersburg, Missouri. He's a lively and clever young boy, and he finds himself in many exciting adventures. He runs away with his two friends, Huck Finn and Joe, to an island in the middle of the Mississippi River for several days. With Huck he goes looking for treasure, with Becky he gets lost in a cave. And finally, they find a box of gold.

    My favourite scene in the book is when everyone thinks Tom is dead. He decides to go to his own funeral. He hides and watches for a time and then suddenly he appears. Everyone is astonished to see him but they're also pleased to see him alive.

    Tom is the hero of the story, but there are other important characters. Huck is an outsider and everyone is afraid of him. Becky is pretty with fair hair, Joe is Tom's best friend. And Injun Joe is the bad man of the story.

    The theme of the story is about children growing up. It describes how strangers are seen in small towns of America. Finally, it talks about freedom, social rules and how people are punished for bad behaviour.

    Why do I think The Adventure of Tom Sawyer is a great book? Mark Twain wrote the story in 1876, but it's still read and loved by people all over the world today. And although it's only a story, Twain wrote it in the everyday English of the southern states of America in the 19th century, so it sounds very real. Today it's thought to be one of the greatest books in American literature. Go on—read it! I know you'll enjoy it, too.

    Often people use laptops(手提电脑) on trains and airplanes, in airports and hotels. These laptops connect people to their workplace. In the United States today, laptops also connect students to their classrooms.

    Westlake College in Virginia will start a laptop computer program that allows students to do schoolwork anywhere they want. Within five years, each of the 1500 students at the college will receive a laptop. The laptops are part of a $10 million computer program at Westlake, a 110-year-old college. The students with laptops will also have access to the Internet. Besides, they will be able to use e-mail to "speak" with their teachers, their classmates and their families. However, the most important part of the laptop program is that students will be able to use computers without going to computer labs. They can work with it at home, in a fast-food restaurant or under the trees—anywhere at all!

    Because of the many changes in computer technology, laptop use in higher education, such as colleges and universities, is workable. As laptops become more powerful, they become more similar to desktop computers. Also, the portable(便携式的)computers can connect students to not only the Internet, but also libraries and other resources. State higher-education officials are also testing laptop programs at other universities, too.

    If you are planning on travelling, there are few simple rules about how to make life easier both before and after your journey.

    First of all, always check and doublecheck departure(出发) time. It is surprising how few people really do this carefully. Once I arrived at the airport a few minutes after ten. My secretary had got the ticket for me and I thought she had said that the plane left at 10:50. When I arrived at the airport, the person at the departure desk told me that my flight was closed. Therefore, I had to wait three hours for the next one and missed an important meeting.

    The second rule is to remember that even in this age of credit cards(信用卡), it is still important to have some local money in cash(现金). Once I arrived at a place at midnight and the bank at the airport was closed. The only way to get to my hotel was by taxi but because I had no dollars, I offered to pay in pounds instead. "Listen! I only take real money!" the driver said angrily. You can image how terrible I felt at that moment.

    The third and the last rule is to find out as much as you can about the weather at your destination before you leave. I feel sorry for some of my workmates who travel in heavy suits and raincoats in May, when it is still fairly cool in London or Manchester, to places like Athens, Rome or Madrid, where it is already beginning to get quite warm during the day.
