    Shopping on the Internet is becoming more and more popular. Why do people use the Internet to shop? Some people say it is more convenient. They don't have to leave their homes to order something;    ①   ; they can find things for sale that they can't find in the stores near their homes.  ②   .

    If you want to buy something on the Internet, you need a credit(信用) card. You have to type your credit card number and information on the website and send them to the store over the Internet. You have to be sure that the store will not use your information in the wrong way. You don't want someone to get your credit card number, so be careful with it, because people sometimes steal credit card numbers from stores.

    The Internet is also a good place to go window-shopping. Window-shopping is when you look at the things for sale in a store, but don't plan to buy anything. In window-shopping you can see what kinds of things you are able to get and how much they cost. Some stores like Ross Stores have a website for information about their stores, but not for shopping. Some stores have a website for information about their stores, and can shop on-line there, such as Office Depot, Payless Shoe Source, Safeway. Some stores like Amazon. com are only for on-line shopping.

    If you go into the forest with friends, stay with them.{#blank#}1{#/blank#}If you do get lost, this is what you should do.

    Sit down and stay where you are. Don't try to find your friends. Let them find you. You can help them to find you by staying in one place.

    {#blank#}2{#/blank#}Give them a signal(信号)outing or whistling (吹口哨) three times. Stop. Then shout or whistle three times again. Any signal given three times is a call for help.

    Keep on shouting or whistling, always three times together. When people hear you, they will give two shouts or two whistles.{#blank#}3{#/blank#}

    If you don't think that you will get help before night comes, try to make a small room with branches(树枝).

    {#blank#}4{#/blank#} ? You would have to leave your little branch room to look for something to eat and drink. Don't just walk away. Pick up small branches and drop them as you walk so that you can find your way back.

    That is all to say.{#blank#}5{#/blank#}

    Have you ever counted the number of digits(数字) in your mobile phone number? Your number has 11 digits. You may sometimes find it hard to remember your number. {#blank#}1{#/blank#}Why is that?

    The 11 digits can be divided into three parts. {#blank#}2{#/blank#}The first three numbers tell you which mobile phone service provider you are using. For example, 135 is for the China Mobile Communication Corporation and 188 is for China Unicom. The fourth to the seventh digits tell you which area the number is recorded in. And the last four digits are random (随机的).

    {#blank#}3{#/blank#}We once had 10 numbers. But as our population grew, there were not enough numbers for us to use. So we began to use 11 digits starting from 1999.

    Eleven digits can be used to make tens of billions of mobile phone numbers, according to the Xinhua News Agency. That's enough for each person to have seven or eight phone numbers to use in China. {#blank#}4{#/blank#}Usually, the service provider will reuse a canceled number after three to six months. If you call a number that you haven't contacted (联络) for a long time, you may find that its owner has changed.

    Besides China, Britain and Japan also use 11-digit mobile phone numbers. But their numbers always start with 0.{#blank#}5{#/blank#}Countries like the United States, Australia and India use phone numbers with l0 digits. Canada's mobile phone numbers are perhaps the world's shortest: they use seven digits.

    Every four years, the best players from all over the world get together in one city to ①________ the world sports meeting the Olympic Games. People carry the holy flame from one place to the nest. On August 6th, 2008, they carried the holy flame to Beijing. All the Chinese people were very happy, excited and proud.

    In Beijing, we built a new Olympic Village with restaurants for players and stadiums for matches.

    The motto of the Olympics is "Faster, higher, stronger". The slogan (标语，口号) of the Beijing Olympics is "②________".

    Jason Queally is one of the fastest men in the world on bicycle. But do you really call the thing in the picture a bicycle? Well, yes, Jason's human-powered machine. With its two wheels, is, of course, a bicycle.

Every year, a very important human powered bicycle is held in Nevada, USA. The speed of a bike is measured (测定) for only 200-metres, but players take more than a kilometer to get their bikes going fast. Jason Queally's fastest speed for the 200metre race was 103.5 kilometers an hour.

    At this year's race, Jason failed to reach the finishing line. He was speeding along at about 70 kilometers an hour when he began to lose control of his bike. When he tried to slow down, it began to smoke. Soon the inside of his bike was filled with smoke. He couldn't see, and he couldn't breathe. At 70 kilometers an hour, a crash could be very serious. Jason was frightened, but he managed to stop the bike safely. He would repair his bicycle and try again another time to be the world's fastest man on a bike. Better luck next time, Jason.

    Maybe you're surprised that these bikes go so quickly, but is it useful? It could be. Cars are becoming more and more popular, and they are very safe, comfortable and easy to drive, but they also pollute the air in our cities. Scientists and engineers are learning from fast racing bikes how to make human-powered vehicles that might be useful for daily travel.
