David will never forget what happened to him the day before yesterday. He (eat) something at home when he received a strange phone call from a hospital. The caller said that his son (fall) to the ground unconscious on the way to school. It was he took him to the hospital. David hung up his cellphone and rushed to his son's classroom, only to find him listening to the teacher attentively. He suddenly realized that he had been cheated, but he felt (relieve). Just at that time the phone rang again, saying, "Your son is in great danger and he needs immediate operation which costs 48,000 yuan. The doctors here say they will not operate your son until they receive the money." When (ask) from where the caller had taken his son to hospital, the caller rang off. David gave a big smile and said, "What a pity!"

    If the cheater thought he could get money from David in such a(n)(honest) way, he was wrong. Such phone calls are common these days. A few of them might have fallen victims to such tricks. Most parents are sensitive to (they). It was really silly to cheat educated men like David.

    Believe it or not, it's a true story. The (colleague) in his office can confirm it, such as Tom, Peter and so on.

    To 1 with a serious leg wound, first of all, it is important to get the victim to lie down. Then remove any clothes from around the wound. Look at the wound and look for any 2 in the wound such as a piece of wood. If there are not any objects, press down hard on the wound. Use a clean cloth to do this. Then, if possible, lift the damaged area. In this case, you need to 3 the leg. Place the damaged leg on something like a box. This will slow down the flow of blood to the wound. Keep the pressure on the wound. Do this for ten 4. Then place a piece of clean cloth over the wound and tie the cloth firmly around the leg. Do not remove the cloth. If blood comes through the cloth, simply place 5 cloth on top. Take the victim to the nearest doctor or hospital.

    With more and more people swimming at beaches every year, the problem of sharks (鲨鱼) takes on new importance. There are people who still insist that sharks never attack human beings unless they are bleeding or wounded, but this belief has not been clearly proved. In the past few years, on both the Atlantic and Pacific coasts, there have been cases of shark attacks which resulted in death. And just how many of the swimmers who have disappeared were victims of shark attacks will never be known. Clearly, these violent fish can be dangerous. Several species are known to attack human beings, and it is believed by some experts that certain sharks, once having tasted human blood, develop a taste for it.

    The chances that one will come across a shark are small, but certain precautions should be taken by everyone. (A precaution is something you do in order to prevent something dangerous or unpleasant from happening.) Putting hands or legs over the side of a boat in warm waters is to be avoided. Swimming far out from beaches is inviting trouble. No swimmer should go great distances from shore alone, or go into the water when nobody else is about. Skin divers, particularly those who go deep down in the water or among rocks and ledges (暗礁) that serve as hiding places for sharks, are taking unnecessary risks.

    If one is in a boat that is rubbed against by a shark, he should remember the creature is not trying to upset his boat; it is probably trying to rub off sea lice (海虱). A blow, especially on the nose, will drive it off. If a swimmer comes across a shark, he should swim away as quietly as possible, trying to avoid making it angry. He should also head for shore (岸) as quickly as possible.

    It's best to plan ahead and there is no better way than to prepare for an emergency before it happens. For example, the time to plan for a fire emergency is before it happens. This is when everyone is calm and clear-thinking. This is when decisions about safe escape routes can be discussed and made. Have a family talk. Don't delay. Planning won't help after a fire starts.

    Knowing ahead of time how to get out during a fire can save needed seconds. The best way out in a fire is the route you use to go in and out every day. Yet, in a fire this route may be blocked. Be sure to plan other escape routes.

    Take each person to his or her room and describe what to do in case of fire. Give everyone a job. Older children should take care of younger ones. Plans may have to be made for anyone who cannot escape without help. Adults who can't walk should sleep on the first floor. Small children should sleep near older persons who can help them. Only healthy, able persons should sleep in hard-to-reach places such as attics or basements.

    Practice your escape plan at night when it is dark. Be sure that your plan is good and will work. For example, make sure that a child can actually open the window he is supposed to use for his escape. Teach children to close their bedroom doors. Tell them to wait by an open window until someone can reach them from outside. If an adult cannot be wakened, children should understand that they must leave by themselves.

    Choose a meeting place outside. This way you can tell if everyone is safely out of the building. Know where nearby telephones or fire alarm boxes are found.

    If you live in an apartment, try to get everyone out. Learn where the fire alarm is in the building. Your family should know what the fire alarm bell sounds like. They should know what to do when they hear it. Try to get the other families in your building together to have fire drills. Write down the telephone number of the fire department. Stick the number to each phone.

    Early warning is the key to a safe escape. It has been shown time and time again that a family can escape if warned early enough.
