    Strange things were happening in Tangshan. For a few days, the water in the wells rose and fell. From the cracks in the well walls, some smelly gas came out. Mice, chickens and pigs became nervous.  people didn't realize that one of the deadly earthquakes was on the way.

    The earthquake which destroyed the city  (shock) the people. At 3:42 am, everything began to shake. It seemed as if the world were coming to  end. In less than one minute, the city lay in ruins. Two thirds of the people died or were  (injure). Then, later that afternoon, another big quake shook Tangshan. However, hope was not lost. Soon after the quakes, soldiers were sent  (rescue) the people. They dug out those who  (trap) and buried the dead. More than 10,000 doctors and nurses came to provide medical care. Workers built shelters for survivors  homes had been destroyed.  (slow), the city began to breathe again.

    With strong support from the government, a new Tangshan was built upon the earthquake ruins. The city has proved  China and the rest of the world that in times of disaster, people must unify and show the  (wise) to stay positive and rebuild for a brighter future.

    On the day the tornado hit, there was no sign that the fierce weather was on its way —the sky was blue and the sun had been out. The first warning my husband, Jimmy, 67, and I, 65, got came around 9 p.m., from some text on the TV Jimmy was watching. He ran upstairs to find me in our third-floor bedroom, and we changed the channel from the national television to our local Pensacola, Florida, station.

    Soon the tornado was on top of us. It was the loudest thing I had ever heard. The house shook, and the power went out. And the wind began to roar (咆哮) through the house, most likely through windows and the door to our garage. Everything was moving. And the back wall of the house came off and flew into the darkness outside. We had three flights of steps to get to the storeroom down there, the relative safety of the first floor.

    I didn't know how or if we would make it down the steps. It felt as if there was no floor as the wind lifted me off my feet. As we finally reached the last flight of steps, our front door blew open. Suddenly, a three-foot-long tree branch (树枝) flew over our heads, missing us by inches.

    By the time I reached the storeroom, the tornado had been over us for about a minute, Jimmy pushed me down to the storeroom floor, but he couldn't get inside himself because of the wind. I held Jimmy's arm as the tornado blew the door open. My knees were full of glass, but I felt no pain. If I had let go, Jimmy would have flown right out of the house.

    All of a sudden, Jimmy lifted off his feet. I thought he was gone. And then everything stopped. He landed on his feet. In those first quiet moments, I couldn't believe it was over. Our neighbor said the storm lasted four minutes. In that time, four of the twelve town houses in our unit were completely destroyed. Luckily, none of us were seriously injured.

    Many people have a fear of public speaking. They try to avoid public speaking because they worry that they will lose their words, bore the audience or somehow make a fool of themselves.  You may give a talk in a class or a meeting. Or you'll give a toast (敬酒) at a wedding. Maybe you'll have to give an acceptance speech for some honor you've received. Follow these steps to satisfy your audience and get rid of your fear of speaking in public.

    Know your topic. Try to speak about a subject you know well.  Public speaking is harder when you look like an outsider.

    Relax.  Your audience don't expect you to be. They want you to succeed just as much as you can do. Get rid of nervousness by giving up all your anxious thoughts. If you're thinking you'll forget everything, remind (提醒) yourself that you are prepared.

     You are not Jack Canfield or Tony Robbins. So, don't try to copy what you think a public speaker should be. Share your true personality with your audience. Don't pretend to be somebody that you're not.

    Pay attention to a few main points.  Your audience will not remember every little detail you tell them. They'll be satisfied if they leave with something they can use, and that is what public speaking is all about.

A. Be yourself.

B. Know who you will speak to.

C. Don't push yourself to be perfect.

D. Everyone has to speak publicly at some point in their life.

E. Research into the topic to make sure that you fully understand the details of it.

F. What's the most important is that you have to be prepared for what you are going to say.

G. You'd better base your speech on 2 or 3 main points and pay attention to these main points.

    I've heard such a story. On a Friday 1, a poor young artist stood at the gate of the subway station, playing his violin. The music was 2, and many people who hurried to go home 3 and put some money into the hat of the young man.

    The next night, the young artist took out a large piece of 4 and laid it on the ground. Then he began 5. The music sounded more pleasant. Some people gathered and they found the 6 on that paper, "Last night, a gentleman put a (n) 7 thing into my hat. Please come to get it back." When the people saw that, they felt very curious and 8 what it could be. After about half an hour, a man 9 there in a hurry and said, "It can't be true! You... you..."

    The young violinist asked, "Did you 10 something?" "A lottery ticket (彩票)," the man answered 11.

    The violinist took out a lottery ticket. “Is it?” he asked.

    The man was too 12 to say a word... He 13 a lottery ticket a few days ago. The awards (奖) opened yesterday and he won $ 500, 000. So lucky and excited did he feel that he 14 50 dollars and put it into the hat when hearing the music. However, the lottery ticket was also thrown into the hat without being 15. After the violinist finished his performance, he 16 the lottery ticket in his hat. 17 that the owner would probably 18 to look for it, he came back to where he was given the lottery ticket.

    Someone asked the violinist why he returned the lottery ticket to the man. He said, "Although I don't have much 19, I live happily; but if I lose 20, I won't be happy forever."

Earthquake -proof (抗震的) buildings

    There are a number of ways  buildings can be made strong enough to stand up to earthquakes. The simplest way is to make them much  (strong). A building strong enough not  (destroy) by a large earthquake, however, would probably look more like a bunker (地堡) than a nice place to live

    So engineers have looked for other ways. One is to make the building that can swing (摇摆) from side to side.  is to design it so that it doesn't sit directly on the ground but on something that allows it to move a bit with the earthquake. If only a small part of a building  (fall) down in an earthquake, damage can be  (great) reduced, so buildings are often designed to do this as well.

    However,  (make) new earthquake -proof buildings is expensive, but with the  (develop) of science and technology more efforts will be made to solve  problem in the future.

    A big fire happened in one office building in our city at about nine o'clock last night. _ (开始时), we saw flames with thick black smoke  (从……冒出) the sixth floor and we also heard the explosion (爆炸声) of the gas tank.  (据说) the fire started at the first floor,  (蔓延到楼上), and finally  (到达顶层). Some windows and brick walls  (被烧毁). Many people stood outside on the streets  (恐惧地观望着这场大火). Many firemen and fire engines came quickly.  (幸运的是), there was no person in the office building when the fire  (爆发). It took about two hours for the firemen to  (扑灭) the big fire.
