21. Soils There are many different kinds of soils. Different soils have different types of rock and minerals in them. Some soils have more water in them than others. Some soils might have more plant and animal material in them, too.Different kinds of soils are found in different parts of the world. There are several kinds of soils found in the United States. In some areas, the soil has a lot of clay. Other soils are very sandy. Loam is a kind of soil that has a good mixture of clay and sand.In some places, soil layers are very thick. Lots of plants grow in places with a thick soil layer. In dry and windy places soil layers are much thinner. Layers of soil on mountains are thin because gravity pulls the soil downhill.The type of soil in a particular place affects what kinds of plants can grow there.22. CrisisLife is a contest! Who will win? A bluebird and sparrow both compete for space to build their nests. A fast-growing maple tree and slower-growing dogwood compete for the sunlight they both need. Oil competes with coal and nuclear power as an energy source for electric power plants!There is a problem. There is a limited amount of space for birds, sunlight for trees, and energy for people! If we do not cut back on our uses of some of our resources, someday they will be gone!How can we use energy today and know we will have enough to go around in the future? We can choose alternate, or replacement, energy resources. It takes the earth millions of years to create coal, oil, and gas. They are nonrenewable resources.Solar energy, wind energy and water energy are renewable resources. It takes the earth millions of years to create coal, oil, and gas. They are nonrenewable resources.Solar energy, wind energy and water energy are renewable. What other ways can we conserve our sources? How can we make sure there is always enough to go around?23. 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.24. Great Depression in the U.S.In 1929, the bills started to come in. American industry had produced too many goods. Americans could not afford to buy all of them. So factories had to cut down on their production. Many workers lost their jobs. Investors tried to get their money back. But businesses did not have enough money to pay them. Banks tried to get their money back from investors. But the investors could not pay, either. Too many people owed money. And few of them could pay their bills. During the next few years, business got worse and worse. By 1932, banks all over the country were closing.People without money could not buy goods. So more businesses closed. More and more people lost their jobs. By 1932, more than 12 million Americans were jobless. Millions more were earning barely enough to live on. The country was in a great depression they had never experienced before.25. 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.28. A Free Dress Every WeekThe temptation to steal is greater than ever before especially in large shops and people are not so honest as they once were.A detective recently watched a well-dressed woman who always went into a large store on Monday mornings. One Monday, there were fewer people in the shop than usual when the woman came in, so it was easier for the detective to watch her. The woman first bought a few small articles. After a little time, she chose one of the most expensive dresses in the shop and handed it to an assistant who wrapped it up for her as quickly as possible. The woman simply took the parcel and walked out of the shop without paying. When she was arrested, the detective found out that the shop assistant was her daughter. Believe it or not, the girl “gave” her mother a free dress every week!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.30. CartoonistsIn a good cartoon, the artist can tell in a few lines as much as a writer can tell in half a dozen paragraphs. The cartoonist not only tells a story but he also tries to persuade the reader to his way of thinking. He has great influence on public opinion. In a political campaign, he plays an important part. Controversial issues in Congress or at meetings of the United Nations may keep the cartoonist well-supplied with current materials.A clever cartoonist may cause laughter because he often uses humor in his drawings. If he is sketching a famous person, he takes a prominent feature and exaggerates it. Cartoonists, for instance, like to lengthen an already long nose and to widen an already broad grin. This exaggeration of a persons characteristics is called caricature. The artist uses such exaggeration to put his message across.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 article.33 Where Do the British Live？Nearly everyone 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.34 Will Computers Replace Human Beings?We are in the computer age today. The computers are working all kinds of wonders now. They are very useful in automatic control and data processing. At the same time, computers are finding their way into the home. They seem to be so clever and can solve such complicated problems that some people think sooner or later they will replace us.But I do not think that there is such a possibility. My reason is very simple: computers are machines, not humans. And our tasks are far too various and complicated for any one single kind of machine to perform.Probably the greatest difference between man and computer is that the former can do things of his own while the latter can do nothing without being programmed. In my opinion, computers will remain nothing but an extension of our human brains, no matter how clever and complicated they may become.35 SoccerSoccer has had a slow start in America. In fact, the majority of schools still have no official soccer teams or coaches. But the blossoming pupularity of the game cannot be denied. Thanks to the efforts of some world-famous soccer stars, soccer is soon to have its place in American culture.Although soccer has enjoyed decades of popularity elsewhere, it was literally ignored in America. Instead, a variation of the game called “football” was most popular in the U.S. and still is to this day. But the obvious advantages of playing soccer instead will soon win even the most avid football enthusiasts.For one thing, soccer is a much safer game to play than football. No one deliberately tries to knock an opponent down in soccer. In fact, the players are discouraged from enen touching each other.Soccer is a game that requires skill and dexerity in controlling the ball. Since no one may use hands to do this, soccer players soon acquire incredible control of their heads, knees, and feet.36. ArtistsEvery artist knows in his heart that he is saying something to the public. Not only does he want to say it well, but he wants it to be something which has not been said before.What visual artists, like painters, want to say is easy to make out but difficult to explain, because painters translate their experiences into shapes and colors, not words. They seem to feel that a certain selection of shapes and colors, out of the countless billions of possible, is exceptionally interesting for them and worth showing to us.Most artists take their shapes and colors from the world of nature and from human bodies in motion and response; their choices indicate that these aspects of the world are worth looking at, that they contain beautiful sights. Contemporary artists might say that they merely choose subjects that provide an interesting pattern, that there is nothing more in it. Yet even they do not choose entirely without reference to the character of their subjects.37 Professioanl Sports in the U.S.Professional sports are not only very popular in the United States, but also a big business. The most popular sports are baseball, football and basketball. Each sport has its own season and individual teams have millions of supporters. Professional teams are named for the cities where they are located. For example, the Lakers are in Los Angeles. The strongest supporters of the Lakers are residents of Los Angeles and Southern California. When the Lakers play, many people in Los Angeles enthusiastically follow the game. When we mention “NBA”, almost every one knows it ahs some relationship with U.S. professional basketball. However, what does it really stand for? N.B.A is gaining new fans and supporters around the world. Basketball has been called the “national pastime”. However, football is the most popular professional sport in the U.S. American football is different from international football, which Americans call “soccer”. Both games require strength and specialized skills.38 “How to” BooksBooks which give instructions on how to do things are popular in the United States today. Thousands of these “how to” books are available. In fact, there are about for thousand books with titles that begin with the words “how to.Many “how to” books give advice on careers. They tell you how to choose a career and how to succeed in it. Many of these books help people to use their free time better. Some people want book which will give them useful information about sports, hobbies and travel. Other people use their free time to make repairs and improvements on their homes. They prefer books which give step-by-step instructions on how to repair things like plumbing and electrical wiring or on how to redecorate or enlarge a house.Why have “how to” books become so popular? Probably because life has become more complex. Today people have far more free to use, more choices to make, and more problems to solve, “how to” books help people to deal with modern life.39. Dont give upIf we would ever accomplish anything in life, let us not forget that we must persevere. If we would learn our lessons in school, we must be diligent and not give up whenever we come to anything difficult. We shall find many of our lessons very hard, but let us consider that the harder they are the better they will do to us if we will preserve and learn them thoroughly.But there are some among us who are ready to give up when they come to a hard example in mathematics, and say, “I cant do this.” They never will if they feel so. “I cant” never does anything worthwhile, but “Ill try” accomplishes wonders.Let us remember that we shall meet with difficulties all through life. They are in the pathway of everyone. If we will only try and keep trying, we shall be sure to conquer and overcome very difficulty we meet.40. How High Can You Jump?Fleas trainers have observed a strange habit of fleas while training them.Fleas are trained by putting them in a cardboard box with a top on it. The fleas will jump up and hit the top of the cardboard box over and over and over again. As you watch them jump and hit the lid, something very interesting becomes obvious. The fleas continue to jump, but they are no longer jumping high enough to hit the top.When you take off the lid, the fleas continue to jump, but they will not jump out of the box. They will not jump out because they cannot jump out. W
