危化品储存设施的防爆技术考核试卷
UNIT 1 What's the matter?P3 3aBus Driver and Passengers Save an Old ManAt 9:00 a.m. yesterday, bus No. 26 was going along Zhonghua Road when the driver saw an old man lying on the side of the road. A woman was next to him, shouting for help.The bus driver, 24-year-old Wang Ping, stopped the bus without thinking twice. He got off and asked the woman what happened. She said that the man had a heart problem and should go to the hospital. Mr. Wang knew he had to act quickly. He told the passengers that he must take the man to the hospital. He expected most or all of the passengers to get off and wait for the next bus.But to his surprise, they all agreed to go with him. Some passengers helped Mr. Wang to move the man ona the bus.Thanks to Mr. Wang and the passengers, the doctors saved the man in time. "It's sad that many people don't want to help others because they don’t want any trouble," says one passenger. "But the driver didn't think about himself. He only thought about saving a life."P6 2bHe Lost His Arm But Is Still ClimbingAron Ralston is an American man who is interested in mountain climbing. As a mountain climber, Aron is used to taking risks. This is one of the exciting things about doing dangerous sports. There were many times when Aron almost lost his life because of accidents. On April 26, 2003, he found himself in a very dangerous situation when climbing in UtahOn that day, Aron's arm was caught under a 2,000-kilo rock that fell on him when he was climbing by himself in the mountains. Because he could not free his arm, he stayed there for five days and hoped that someone would find him. But when his water ran out, he knew that he would have to do something to save his own life. He was not ready to die that day. So he used his knife to cut off half his right arm. Then, with his left arm, he bandaged himself so that he would not lose too much blood. After that, he climbed down the mountain to find help.After losing his arm, he wrote a book called Between a Rock and a Hard Place. This means being in a difficult situation that you cannot seem to get out of. In this book, Aron tells of the importance of making good decisions, and of being in control of one's life. His lose for mountain climbing is so great that he kept on climbing mountains even after this experience.Do we have the same spirit as Aron? Let's think about it before we find ourselves “between a rock and a hard place”, and before we have to make a decision that could mean life or death.Unit 2 I'll help to clean up the city parksP11 3aStudents Who VolunteerMario Green and Mary Brown from Riverside High School give up several hours each week to help others.Mario loves animals and wants to be an animal doctor. He volunteers at an animal hospital every Saturday morning. Mario believes it can help him to get his future dream job. “ It' s hard work , ” he says , “but I want to learn more about how to care for animals . I get such a strong feeling of satisfaction when I see the animals get better and the look of joy on their owners' faces.”Mary is a book lover. She could read by herself at the age of four. Last year she decided to try out for a volunteer after-school reading program .she still works there once a week to help kids learn to read. The kids are sitting in thelibrary, but you can see in their eyes that they’re going on a different journey with each new book. V olunteering here is a dream come true for me. I can do what I love to do and help others at the same time.Most people today are only worried about getting good jobs lots of money. In their free time, They think about what for fun or relaxation. However, few people think about what they can do others. There are many people who are less lucky than us. V olunteering our time to help these people is a good way our free time. For example, we can make plans sick children in the hospital or raise money for homeless people. Some people even stop doing their jobs for a few months to a year to another country, like Africa, and help people there.P14 2bI’ll Send Y ou a Photo of LuckyDear Miss Li,I’d like to thank you for sending money to Animal Helpers. I’m sure you know that this group was se t up to help disabled people like me. You helped to make it possible for me to have Lucky. Lucky makes a big difference to my life. Let me tell you my story.What would it be like to be blind or deaf? Or imagine you can’t walk ou use your hands easily. Mos t people would never think about this, but many people have these difficulties. I can’t use my arms or legs well, so normal things like answering the telephone, opening and closing doors, or carrying things are difficult for me. Then one day last year, a friend of mine helped me out. She talked to Animal Helpers about getting me a special trained dog. She also thought a dog might cheer me up. I love animals and I was excited about the idea of having a dog.After six months of training with a dog at Animal H elpers, I was able to bring him home. My dog’s name is Lucky — a good name for him because I feel very lucky to have him. You see, I’m only able to have a “dog-helper” because of your kindness! Lucky is very clever and understands many English words. He can understand me when I give him orders. For example, I say, “Lucky! Get my book,” and he does it at once.Lucky is a fantastic dog. I’ll send you a photo of him if you like, and I could show you how he helps me. Thank you again for changing my life.Best wishes,Ben SmithP16 Self-check 2Last week, everyone was trying up Jimmy, the Bike boy. He was unhappy because he of money old bikes. He some signs asking for old bikes and all his friends on the phone them about the problem. He even notices at the supermarket. Then he told the teachers at school about his problem and they a call-in center for parents. The ideas that he with worked out fine. He now has 16 bikes up and to children who don’t have bikes.Unit 3 Could you please clean your room?P19 3aLast month, our dog welcomed me when I came home from school. He wanted a walk, but I was too tired.I threw down my bag and went to the l iving room. The minute I sat down in front of the TV, my mom came over. “Could you please take the dog for a walk?” she asked.“Could I watch one show first?” I asked. “NO!” she replied angrily. “You watch TV all the time and never help out around the hous e! I can’t work all day and do housework all evening.”“Well, I work all day at school, too! I’m just as tired as you are!” I shouted back.My mom did not say anything and walked away. For one week, she did not do any housework and neither did I. Finally, I could not find a clean dish or a clean shirt.The next day, my mom came home from work to find the house clean and tidy.“What happened?” she asked in surprise.“I’m so sorry, Mom. I finally understand that we need to share the housework to have a clean and comfortable home,” I replied.P22 2bDear Sir,I don’t understand why some parents make their kids help with housework and chores at home. Kids these days already have enough stress from school. They don’t have time to study and do housework, too. Hous ework is a waste of their time. Could we just let them do their job as students? They should spend their time on schoolwork in order to get good grades and get into a good university. Also, when they get older, they will have to do housework so there’s no need for them to do it now. It is the parents’ job to provide a clean and comfortable environment at home for their children. And anyway, I think doing chores is not so difficult. I don’t mind doing them.Mr. SmithDear Sir,I think it is important for chi ldren to learn how to do chores and help their parents with housework. It’s not enough to just get good grades at school. Children these days depend on their parents too much. They’re always asking, “Could you get this for me?” or “Could you help me with that?” Doing chores helps to develop children’s independence and teaches them how to look after themselves. It also helps them to understand the idea of fairness. Since they live in one house with their parents, they should know that everyone should do thei r part in keeping it clean and tidy. Our neighbor’s son got into a good college but during his first year, he had no idea how to take care of himself. As a result, he often fell ill and his grades dropped. The earlier kids learn to be independent, the better it is for their future.Ms. MillerUnit 4 Why don’t you talk to your parents?P27 3aDear Mr. Hunt,My problem is I can’t get on with my family. Relations between my parents have become difficult.They fight a lot, and I really don’t like it. It’s the only communication they have. I don’t know if Ishould say anything to them about this. When they argue, it’s like a big, black cloud hanging overour home. Also, my elder brother is not very nice to me. He always refuses to let me watch myfavorite TV show. Instead he watches whatever he wants until late at night. I don’t think this isfair. At home I always feel lonely and nervous. Is that normal? What can I do?Sad and ThirteenDear Sad and Thirteen,It’s not easy being your age, and it’s normal to have these feelings. Why don’t you talk about thesefeelings with your family? If your parents are having problems, you should offer to help. Maybeyou could do more jobs around the house so that they have more time for proper communication.Secondly, why don’t you sit down and communicate with your brother? You should explain thatyou don’t mind him watching TV all the time. However, he should let you watch your favoriteshow. I hope you’ll feel better about yourself in future.Robert HuntP30 2bMaybe You Should Learn to Relax!These days, Chinese children are sometimes busier on weekends than weekdays because they to take so many after-school classes. Many of them are learning exam skills so that they can get into a good high school and later a good univers ity. Others are practicing sports so that they can compete and win. However, this doesn’t only happen in China. The Taylors are a typical American family. Life for Cathy Taylor’s three children is very busy.” On most days after school,” Cathy says, “I take one of my two boys to basketball practice and my daughter to football training. Then I have to take my other son to piano lessons. Maybe I could cut out a few of their activities, but I believe these activities are important for my children’s future. I really want them to be successful. ” However, the tired children don’t get home until after 7:00 p.m. They have a quick dinner, and then it’s time for homework.Linda Miller, a mother of three, knows all about such stress. “In some families, competition star ts very young and continues until the kids get older,” she says. “Mothers send their small kids to all kinds of classes. And they are always comparing them with other children. It’s crazy. I don’t think that’s fair. Why don’t they just let their kids be ki ds? People shouldn’t push their kids so hard.”Doctors say too much pressure is not good for a child’s development. Dr. Alice Green says all these activities can cause a lot of stress for children. “Kids should have time to relax and think for themselves, too. Although it’s normal to want successful children, it’s even more important to have happy children.”Unit 5 What were you doing when the rainstorm came?P35 3aThe Storm Brought People Closer TogetherBen could hear strong winds outside his home in Alabama. Black clouds weremaking the sky very dark. With no light outside, it felt like midnight. The newson TV reported that a heavy rainstorm was in the area.Everyone in the neighborhood was busy. Ben’s dad was putting pieces of wood over the windows while his mom was making sure the flashlights and radio were working. She also put some candles and matches on the table.Ben was helping his mom make dinner when the rain began to beat heavily against the windows. After dinner, they tried to play a card game, but it was hard to have fun with a serious storm happening outside.Ben could not sleep at first. He finally fell asleep when the wind was dying down at around 3:00 a.m. When he woke up, the sun was rising. He went outside with his family and found the neighborhood in a mess. Fallen trees, broken windows and rubbish were everywhere. They joined the neighbors to help clean up the neighborhood together. Although the storm broke many things apart, it brought families and neighbors closer together.P36 4bFill in the blanks with was, were, when or while.At 7:00 a.m., I woke up. ______________ I______________making my breakfast, my brother______________listening to the radio. ______________I was eating, the radio news talked abouta car accident near our home.

But luckily, the driver_______________fine. The roads_______________icy because of the heavy snow from the night before.P38 2bDo You Remember What You Were Doing?People often remember what they were doing when they heard the news of important events in history. In America, for example, many people remember what they were doing on April 4, 1968. This was an important event in American history. On this day, Dr. Martin Luther King was killed. Although some people may not remember who killed him, they remember what they were doing when they heard the news.Robert Allen is now over 50, but he w as a school pupil at that time. “It was a bright, sunny day,” Robert remembers. “We were having fun in the playground when the school bell rang. Our teacher said, ‘Dr. King died just 10 minutes ago.’ We were completely surprised!” School closed for the day, Robert and his friends walked home in silence.More recently, most Americans remember what they were doing when the World Trade Center in New York was taken down by terrorists. Even the date-September 11, 2001-has meaning to most Americans.This was a da y Kate Smith will never forget. She remembers working in her office near the two towers. “My friend shouted that a plane just hit the World Trade Center! I didn’t believe him at first, but then I looked out the window and realized that it was true. I was s o scared that I could hardly think clearly after that.”P40 Self- check 2When I ____________ (be) in the sixth grade, I __________(join) a piano competition.

Most of them were hearing this story for the first time. However, this story is not new to Chinese children. The Monkey King or Sun Wukong is the main character in the traditional Chinese book Journey to the West.The story says that once upon a time there was a magic rock. One day, it suddenly broke open and gave birth to a monkey. To fight bad people, the Monkey King uses a magic stick.Sometimes he can make the stick so small that he can keep it in his ear. At other times, he is able to make it big and long. Sun Wukong can also make 72 changes to his shape and size, turning himself into different animals and objects. But unless he can hide his tail, he cannot turn himself into a person.The Monkey king has excited the children of China many years. And as soon as the TV program came out more than 30 years ago, Western children became interested in reading this story because the clever Monkey King keeps fighting to help the weak and never gives up.P44 4bThe Monkey King is the main character from the famous Chinese story Journey to the West.

So I will not give up and I will wait for another ship. I have already cut down trees and built a house. I go out with my gun almost every day to kill animals and birds for food. I’m even learning to grow fruits and vegetables.A few weeks ago, I found the marks of another man’s feet on the sand. Who else is on my island? How long have they been here?

But five years ago, while she wasstudying abroad in England, she heard a song full of feelings about returning home on the radio. It made Sarah think about her family and friends back in the US. She came to realize how much she actually missed all of them. Ever since then, she has been a fan of American country music.Country is a traditional kind of music from the southern states of America. Nashville, Tennessee is the home of country music. Many songs these days are just about modern life in the US, such as the importance of money and success, but not about belonging to a group. However, country music brings us back to the “good old days” when people were kind to each other and trusted one another. It reminds us that the best things in life are free—laughter, friends, family, and the beauty of nature and the countryside.Sarah hasn’t been to Nashville yet, but it is her dream to go there one day. She has already read a lot about the place and done some research on it. She knows that there is a Country Music Hall of Fame Museum in Nashville. There are also always a lot of great country music concerts with famous musicians and singers, like Garth Brooks. Sarah has already listened to most of his songs. “Garth is one of the most successful musicians in American history. He’s sold more than 120 million records. I hope to see him sing live one day!”Unit 9 Have you ever been to a museum?P68 4bMost of us______(see)Mickey Mouse, Donald Duck and other famous Disney characters in cartoons before.

On the boat, you can________(shop)and have Disney parties before you_________(arrive) at the Disney island.P70 2bUnit 10 I've had this bike for three years.P75 3aMy children are growing up fast. My daughter is 16 and my boy has just started junior high school. As they get bigger our house seems to get smaller. So we’ve been clearing out a lot of things from our bedrooms for a yard sale.We’ve decided to each sell five things we no longer use. We’ll give the money we raise to a children’s home. My son was quite sad at first. He found a lot of toys that he doesn’t play with anymore but still wanted to keep. For example, he’s owned a train and railway se t since his fourth birthday, and he played with it almost every week until he was about seven. And he didn’t want to lose the toy monkey he’s had since birth. I remember when he would never go to bed without it. My daughter was more understanding, although she also felt sad to part with certain toys. As for me, I didn’t want to give up my football shirts, but, to be honest, I haven’t played for a while now. I’m getting older, too!P78 2aHometown FeelingsSome people still live in their hometown. However, others may only see it once or twice a year. Nowadays, millions of Chinese leave the countryside to search for work in the cities. Among these is Zhong Wei, a 46-year-old husband and father. He has lived in Wenzhou for the last 13 years. With a hard job in a crayon factory, he doesn’t find much time to visit his hometown. “I used to return home at least once a year, but I haven’t been back for almost three years now. It’s a shame, but I just don’t have the time,” he says.Many people like Zhong Wei regard with great interest how their hometowns have changed. Perhaps large hospitals and new roads have appeared. In many places, the government has also built new schools and sent teachers from the cities to help.“I noticed that’s true of my hometown,” adds Zhong Wei. “Children have learned to read and count at my old primary school since the mid-20th century. But now the buildings are really old. I hear they’re going to build a new school there.” Zhong Wei thinks such developments are good, and he also knows that his hometown cannot always stay the same. According to Zhong Wei, however, some things will never change. “In my hometown, there was a big old tree opposite the school. It is still there and has become quite a symbol of the place. Most of the children in my time liked to play together under that big tree, especially during the summer holidays. It was such a happy childhood. Our hometown has left many soft and sweet memories in our hearts.”P79 2cMany Chinese people these days leave their to work in the . They usually to their hometowns one or two times a________. Zhong Wei hasn’t been back in close to three years. He has been working in a factory in Wenzhou for the past 13 years.People like him are in how their hometowns are changing. New buildings are often built by the . Zhong Wei thinks these changes are because things need to change in order to become better. But he also thinks some things change, and his hometown is still the place that holds all his childhood .。
