3.A Popular Pastime of the English PeopleOne of the best means of understanding the people of any nation is watching what the do with their non-working time.Most English men, women and children love growing things, especially flowers. Visitors to England in spring, summer or autumn are likely to see gardens all they way along the railway lines. There are flowers at the airports and flowers in factory grounds, as well as in gardens along the roads. Each English town has at least one park with beautifully kept flower beds. Public buildings of every kind have brilliant window boxes and sometimes baskets of flowers are hanging on them.But what the English enjoy most is growing things themselves. If it is impossible to have a garden, then a window box or something growing in a pot will do. Looking at each others gardens is a popular pastime with the English.4. British and American Police OfficersReal policemen, both in Britain and the U.S., hardly recognize any common points between their lives and what they se on TVif they ever get home in time. Some things are almost the same, of course, but the policemen do not think much of them much of them. The first difference is that a policemans real life deals with the law. Most of what he learns is the law. He has to know actually what actions are against the law and what facts can be used to prove them in court. He has to know nearly as much law as a lawyer, and whats more, he has to put it into practice on his feet, in the dark and, running down a narrow street after someone he wants to talk to.Little of his time is spent in talking with beautiful girls or in bravely facing cruel criminals. He will spend most of his working life arranging millions of words on thousands of forms about hundreds of sad, ordinary people who are guilty- or not of stupid, unimportant crimes.Useful Words and Expressions:1. think much of 重视，尊重2. in court 在法庭上3. criminal 罪犯，犯罪者4. guilty 犯罪的，有罪的5. Living SpaceHow much living space does a person need? What happens when his space needs are not met? Scientists are doing experiments on rats to try to determine the effects of overcrowded conditions on man. Recent studies have shown that the behavior of rats is greatly affected by space. If rats have enough living space, they eat well, sleep well and produce their young well. But if their living conditions become too crowded, their behavior and even their health change obviously. They can not sleep and eat well, and signs of fear and worry become clear. The more crowded they are, and more they tend to bite each other and even kill each other. Thus, for rats, populations and violence are directly related. Is this a natural law for human society as well? Is enough space not only satisfactory, but necessary for human survival? These are interesting questions.6. The United NationsIn 1945, representatives of 50 nations met to plan this organization. It was called the United Nations. After the war, many more nations joined.There are two major parts of the United Nations. One is called the General Assembly. In the General Assembly, every member nation is represented and has an equal vote.The second part is called the Security Council. It has representatives of just 15 nations. Five nations are permanent members: the United States, Russia, France, Britain, and China. The 10 other members are elected every two years by the General Assembly.The major job of the Security Council is to keep peace in the world. If necessary, it can send troops from member nations to try to stop little wars before they turn into big ones.It is hard to get the nations of the Security Council to agree on when this is necessary. But they did vote to try to stop wars.Useful Words and Expressions:1. representative 代表2. General Assembly 联合国大会3. permanent 永久的，持久的4. Security Council 联合国安全理事会7. PlasticWe use plastic wrap to protect our foods. We put our garbage in plastic bags or plastic cans. We sit on plastic chairs, play with plastic toys, drink from plastic cups, and wash our hair with shampoo from plastic bottles!Plastic does not grow in nature. It is made by mixing certain things together. We call it a produced or manufactured material. Plastic was first made in the 1860s from plants, such as wood and cotton. That plastic was soft and burned easily.The first modern plastics were made in the 1930s. Most clear plastic starts out as thick, black oil. That plastic coating inside a pan begins as natural gas.Over the years, hundreds of different plastics have been developed. Some are hard and strong. Some are soft and bendable. Some are clear. Some are many-colored. There is a plastic for almost every need. Scientists continue to experiment with plastics. They hope to find even ways to use them!10. Private CarsWith the increase in the general standard of living, some ordinary Chinese families begin to afford a car. Yet opinions of the development of a private car vary from person to person.It gives a much greater degree of comfort and mobility. The owner of a car is no longer forced to reply on public transport, and hence no irritation caused by waiting for buses or taxis. However, others strongly object to developing private cars. They maintain that as more and more cars are produced and run in the street, a large volume of poisonous gas will be given off, polluting the atmosphere and causing actual harm to the health of people.Whether private cars should be developed in Chicago is a difficult question to answer, yet the desire for the comfort and independence a private car can bring will not be eliminated. 12. A Young Mans PromiseOne day, a young man was writing a letter to his girlfriend who lived just a few miles away in a nearby town. He was telling her how much he loved her and how wonderful he thought she was. The more he wrote the more poetic he became. Finally he said that in order to be with her, he would suffer the greatest difficulties, he would face the greatest dangers that anyone couldnt imagine. In fact, to spend only one minute with her, he would swim across the widest river, he would enter the deepest forest, and he would fight against the fiercest animals with his bare hands.He finished the letter, signed his name and then suddenly remembered that he had forgotten to mention something quite important. So, in a postscript below his name, he added:“By the wThat Isnt Our Fault14.Mr. and Mrs. Williams got married when he was twenty-three, and she was twenty. Twenty-five years later, they had a big party, and a photographer came and took some photographs of them.Then the photographer gave Mrs. Williams a card and said, “Theyll be ready next Wednesday. You can get them from studio.”“No,” Mrs. Williams said, “please send them to us.”The photographs arrived a week later, but Mrs. Williams was not happy when she saw them. She got into her car and drove to the photographers studio. She went inside and said angrily, “You took some photographs of me and my husband last week, but Im not going to pay for them.”“Oh, why not?” the photographer asked.“Because my husband looks like a monkey,” Mrs. Williams said.“Well,” the photographer answered, “that isnt our fault. Why didnt you think of that before you married him?”ay, Ill be over to see you on Wednesday night, if it doesnt rain.”17. Living Things ReactYou and all organisms live an environment. An environment is made up of everything that surrounds an organism. It can include the air, the water, the soil, and even other organisms.An organism responds to changes in its environment. When an organism responds to a change, it reacts in certain ways. All living things respond in some way.Have you ever noticed how plants and insects respond to light? Plants bend toward light. Insects fly toward light.Living things also respond in other ways. The leaves on some trees respond to a change in season. In autumn, they change colors and then fall off the branches Animals also respond to a change in season. Squirrels save nuts for the winter. Bears sleep through the winter in a cave.You respond to your environment in many ways, too. You may shiver if you are cold. What other ways do you respond to changes in your environment?18. Flowering PlantsWhat are the parts of a flower?Flowers can have male parts and female parts. The female parts make eggs that become seeds. The male parts make pollen. Pollen is a powdery material that is needed by the eggs to make seeds. To make seeds, pollen and eggs must come together. The wind, insects, and birds bring pollen to eggs. Many animals love flowers bright colors. They also like a sugary liquid in flowers. This is called nectar. While they drink nectar, pollen rubs off on their bodies. As they move, some of this pollen gets delivered to the female flower parts.Over time, the female parts turn into fruits that contain seeds. Animals often eat the fruits and the seeds pass through their bodies as waste. The animals do no know they are working for the plants by planting seeds as they travel to different places!Useful words and Expressions:1. flowering 开花的2. pollen 花粉3. powdery 粉状的4. sugar 含糖的，甜的5. nectar花蜜，甘露19. Finding the Direction and LocationHow can you tell which direction? By day, look for the Sun. It is in the east in the morning and the west in the afternoon. At night, use the Big Dipper to help you find the North Star. It would be better to bring a compass because its needle always points north.How do you know how far you have gone? You could count every step. Each step is about two feet. Youd better wear a pedometer which is a tool that counts steps. If you know where you started, which direction you are heading, and how far you have gone, you can use a good map to figure out exactly where you are.Today there is a new way for travelers to figure out where they are. It is the GPS. It has 24 satellites that orbit the earth and constantly broadcast their positions. Someday you may carry a small receiver as you hike and use GPS to find out if you are there yet!Useful Words and Expressions:1. dipper北斗七星2. compass 罗盘3. pedometer 步数计4. GPS= Global Position System全球定位系统5. orbit 轨道，绕轨道而行6. receiver 接收器20. Americas Worst SurpriseDecember 7, 1941 was one of the worst days in American history. Nearly all Americans who are old enough to remember that day can still remember what they were doing at the moment they heard “the news”. The news was that America had been attacked!Shortly before 2:00 P.M., a radio dispatch came into Washington from Honolulu, Hawaii. “Air Raid, Pearl Harbor This is no drill.” Japanese planes had begun an attack on the largest American military base in the Pacific. They first destroyed planes on the ground. Then they bombed the ships in the harbor.No one had expected the attack. So no one was prepared for it. And it did not take long for Japanese to do their damage. When the smoke cleared, the Navy counted its losses. Eighteen ships had been sunk or badly damaged. Nearly 150 planes had been destroyed. More than 2,400 Americans had been killed and more than 1,200 wounded.Useful Words and Expressions:1. dispatch 派遣，急件2. air raid 空袭3. drill 军事训练，操练4. Pearl Harbor 珍珠港23.A Place of Our OwnWe are all usually very careful when we buy something for the house. Why? Because we have to live with it for a long time. We paint a room to make it brighter, so we choose the colors carefully.We buy new curtains in order to match the newly decorated room, so they must be the right color. We move the furniture round so as to make more spaceor we buy new furnitureand so on. It is an endless business.Rich or poor, we take time to furnish a room. Perhaps some people buy furniture in order to impress their friends. But most of us just want to enjoy our surroundings. We want to live as comfortably as we can afford to. We spend a large part of our lives at home. We want to make a small corner in the world which we can recognize as our own.26.Travel for WorkYou can see them in every airport in the world. They are businessmen and women who have to travel for their work.When they first applied for the job, they may have thought of good food and hotels, huge expense accounts and fashionable cities. Now they have to sit in airport lounges, tired and uncomfortable in their smart clothes, listening to the loudspeaker announce “The fight of Tokyo, or Berlin, or New York is delayed for another two hours.” Some people say to me, “How lucky you are to be able to travel abroad in your work! You can go sightseeing without paying any money by yourself!” They think that my job is like a continual holiday. It is not.There are advantages, of course, and I do thin I am lucky, but only because I can go to places I would never visit if I was a tourist. 27. IntelligenceAre some people born clever, and others born stupid? Or is intelligence developed by our environment and our experience?Strangely enough, the answer to these questions is yes. To some extent our intelligence is given us at birth, and no amount of special education can make a genius out of a child born with low intelligence. On the other hand, a child who lives in a boring environment will develop his intelligence less than one who lives in rich and varied surroundings. Thus, the limits of a persons intelligence are fixed at birth, whether or not he reaches those limits will depend on his environment. This view, held by most experts now, can be supported in a number of ways. As is easy to show that intelligence is to some extent something we are born with. The closer the blood relationship between two people is, the closer they are likely to be in intelligence.29. TimeTime is tangible. One can gain time, spend time, waste time, save time, or even kill time. Common questions in American English reveal this concrete quality as though time were a possession. “Do you have any time?”, “Can you get some time for this?”, “How much free time do you have?” The treatment of time as a possession influences the way that time is carefully divided.Generally, Americans are taught to do one thing at a time and may be uncomfortable when an activity is interrupted. In businesses, the careful scheduling of time and the separation of activities are common practices. Appointment calendars are printed with 15-,30-, and 60-minute time slots. The idea that “there is a time and place for everything” extends to American social life. Visitors who drop by without prior notice may interrupt their hosts personal time. Thus, calling friends on the telephone before visiting them is generally preferred to visitors dropping by.Useful words and expressions:1. tangible 切实的2. kill time 消磨时间3. reveal 显示，揭示4. scheduling 行程安排5. slot 缝隙6. drop by 随便访问7. preferred 首选的31. Water PollutionWater is very important to us. Factories and plants need water for industrial uses and large pieces of farmland need it for irrigation. Without water to drink, people die in a short time.Today most water sources are so dirty that people must purify water before drinking. Water becomes dirty in many ways: industrial pollution is one of them. With the development of industry, plants and factories pour tons of industrial wasters into rivers every day. The rivers have become seriously polluted, and the water is becoming unfit for drinking or irrigation. The same thing has also happened to our seas and oceans. So, the problem of water pollution is almost worldwide.Scientists of many countries have done a lot of work to stop pollution. The polluted water in some places has become clean and drinkable again. Perhaps one day the people in all towns and cities will be drinking clean water. That day, we believe, is not very far off.32. Making a ComplaintComplaining about faulty goods or bad services is never easy. But if something you have brought is faulty or does not do what was claimed for it, you are not asking for a favor to get it put right.Complaints should be made to a responsible person. Go back to the shop where you bought the goods, taking with you any receipt you may have. In a small store the assistant may also be the owner so you can complain direct. In a chain store, ask the manager. If you telephone, ask the name of the person who handles your enquiry, otherwise you may never find out who dealt with the complaint later. If you do not want to do it in person, write a letter. Stick to the facts and keep a copy of what you write. At this stage you should give any receipt numbers, but you should not need to give receipts or other papers to prove you bought the article33. Where Do the British Liveeveryone in Britain would like to own their own home and, whether they do or not, they are prepared to put time and money into decorating and furnishing it or even making structural alterations to it. Because of the climate and because of the expense involved in going out for the evening, the British spend a lot of time at home and a large part of their social life takes place there.Young people tend to stay with their families longer these days as accommodation is expensive but, when they move away to a job or college, there are various options open to them. They can get lodgings with a landlady. This means that they rent a room in someones house and have breakfast with the family. They can also get a bed-sitting room, that is to say one self-contained room in which they can cook, live and sleep. Alternatively, they can share a rented flat or house with a group of young people, perhaps the most popular option of all.Useful Words and Expressions:1. lodging 寄宿处2. bedsit 卧室兼起居室3. bed-sitting 卧室兼起居室的4. self-contained 设备齐全的34. Will Computers Replace Human Beings?We are in the computer age today. The computers are working all kinds of wonders
