One morning Mrs. Smith was1 home after she had been shopping. When she 2near a rubbish dump, she noticed a microwave(微波炉) not far3the side of the road. She stopped her car and looked 4the oven.

    "John is a good 5 ," she said to herself. "Perhaps he6repair this. I'll take it home and let him 7. "

    She 8the oven and put it in the boot(行李箱) of her car. Then she drove on 9. A few kilometers later, she heard the siren(警报器声) of a police car10her. She looked in the driving mirror and 11 a policeman waving to her to tell her to stop.

    Mrs. Smith was very puzzled. She 12down and then stopped at the side of the road. A 13policeman got out of the police car and walked to her.

    "What's wrong, officer?" Mrs. Smith asked.

    The policeman did not reply. He looked in the car and then at the 14 .

    "I found the microwave oven a few minutes ago," she said, "I'm just taking it home to see if my husband can repair it. "

    "That's not a microwave oven," he said at last, "That's our radar set. It was the start of a speed trap. "

    Mrs. Smith's face turned15, "Oh," she said, "I'm sorry. I didn't know what it was. "

    Today, an increasing number of people are always looking at their mobile phones with their heads down. These people are called the " Heads-down Tribe (低头族)". Are you a heads-down tribe member? Heads-down tribe members now can be seen everywhere.

    More and more traffic accidents are happening because more drivers use mobile phones when they are driving. In order to make drivers pay more attention to driving, some new traffic rules have been made. For example, people who use mobile phones while driving in Taiwan are fined (罚款). Car drivers and motorcyclists who break the traffic rule will be fined NT $ 3,000 and NT $1,000 respectively.

    As we can see above, using mobile phones may cause accidents and even cost a lot of money. Also, more and more interesting and strange facts happen to the "Heads-down Tribe". Let's have a look at an interesting TV report:

    A man in America kept using his mobile phone on his way home. As a result, he knocked into a big lost bear. When he lifted his eyes from the phone, he was so afraid that he turned around and ran away quickly.

    Another fact is that we can often see people in the restaurant eating face to face but looking at their own mobile phones. It's strange that they don't talk to the ones who sit opposite to them during the meal. Some of them even have fun communicating with others on the phone.

    Mobile phones are helpful and necessary tools for modern life. Are mobile phones good or bad? It depends on how people use them.  Let's be "healthy" users and try to be the "Heads-up Tribe".

    Emergencies(紧急情况) don't happen very often. But when they do, you want to get help first. No one wants to spend time looking up the phone numbers.

    In 1968, the Untied States government wanted one number that people could call for emergencies. They decided that 911 was easy to remember and people could dial it quickly. The very first 911 call was made on February 16, 1968 in Alabama. Today, 911 is used for emergencies in most parts of the United States and many parts of Canada.

    Other countries may use other numbers. In Great Britain, it's 959. If you're not sure which emergency number is used in your area, check your phone book.

When to call

    Never call 911 as a joke or just to see what might happen. The only time you should call 911 is when a person is badly hurt or in danger right now! So call when there is a fire, a car accident, or sudden illness, etc.

When in an emergency call

    When you dial the 911 operator(接线员), it's always OK to give out your information. Speak slowly and clearly when you explain what's happening. What happened? Where are you? Who needs help?

Don't hang up(挂断)!

    If you have to call 911, do not hang up until the operator tells you it's OK to do so. That way, you can be sure that the operator has all the information to offer help fast.

    A dog named Faith dialed 911 when her owner who was in a wheelchair fell and needed help. She had been taught to use a speed-dial(快速拨号) function.
