Ques: We always read reports about costs of oil going up and we will think this is our most valuable material. However, water is the most valuable resource . People in the Middle East are more worried about this than oil. Maybe the next war will be about water. In the future, to control the quality and quantity , you will use different water for different usages. The water used to wash your car, water your flowers or wash your clothes doesn't need to be as clean as the water you drink. One in five people live in countries without enough fresh water and in 25 years, the number is believed to be one in every three people. Our world population is increasing. What do you suppose this will suggest for us in the future? Population control? Traditional management of the water industry has been out of date since the 1990s. When technologies develop so rapidly in the world, we have loads of information for technologies in the business world, but in the water industry we don't have any. Britain and France have already taken measures to successfully improve their water industries. All the water services in Britain have been provided by private  companies since 1991. Since then, improvement has been made in the rules for their water quality and pricing. What can you do now for the future? Using water more efficiently  in your house can make a great difference not only to the world but to your money. Even if you don't have to pay much now, you will when you start to pay big prices for different water usages. Britain has improved their water quality by   _  . A) raising the price of water.

Ques: Reading is the key to school success and, like any skill, it takes practice. A child learns to walk by practicing until he no longer has to think about how to put one foot in front of the other. An excellent sportsman practices until he can play quickly, correctly and without thinking. Educators call it "automaticity  ".  www.ks5u.com A child learns to read by sounding out the letters and finding the meaning of the words. With practice, he stumbles less and less, reading by the phrase  . With automaticity, he doesn't have to think about the meaning of words, so he can give all his attention to the meaning of the text. It can begin as early as first grade. In a recent study of children in Illinois schools, Alan Rossman of Northwestern University found that automatic readers in the first grade not only read almost three times as fast as the others, but also got better results in exams. According to Rossman, the key to automaticity is the amount   of time a child spends reading , not his IQ. Any child who spends at least 3.5 to 4 hours a week reading books, magazines or newspapers will probably reach automaticity. It can happen if a child turns off TV just one night for reading at home. You can test yourself by reading something new which is suitable   for your level. If you read aloud with expression, with a sense of the meaning of the sentences, you probably are an automatic reader. If you read brokenly, one word at a time, without expression or meaning, you need more practice. Rossman tells that any child who_will possibly be an automatic reader. A) turns off TV one night 4 weeks B) reads books by the word quickly C) spends an hour reading every day D) gets the same grades as others in exams
Ans: C

Ques: The traditional distinction between products that satisfy needs and those satisfy wants is no longer adequate to describe classes of products. In today's prosperous societies, the distinction has become unclear because so many wants have been turned into needs.A writer, for instance, can work with paper and pencils. These are legal needs for the task.But the work can be done more quickly and efficiently with a word processor. Thus a computer is soon viewed as a need rather than a want. In the field of marketing, consumer goods are classed according to the way in which they are purchased.The two main classes are convenience goods and shopping goods.Two lesser types are specialty goods and unsought   goods. It must be emphasized that all of these types are based on the way shoppers think about products, not on the nature of the products themselves. What is regarded as a convenience item in France(wine,for example)should be a specialty goods in the United States. People do not spend a great deal of time shopping for such convenience items as groceries, newspapers, toothpaste, aspirin, and candy. The buying of convenience goods may be done routinely, as some families buy groceries once a week. Such regularly purchased items are called staples. Sometimes convenience products are bought without enough thinking; someone has a sudden desire for an ice cream sundae on a hot day. Or they may be purchased as emergency items. Shopping goods are items for which customers search. They compare prices. quality, and styles, and may visit a number of stores before making a decision.Buying an automobile is often done this way. Shopping goods fail into two classes:those that are recognized as basically the same and those that are regarded as different. Items that are looked upon as basically the same include such things as home appliances, television sets, and automobiles.Having decided on the model desired, the customer is primarily interested in getting the item at the most favorable price. Items regarded as essentially... Shopping goods that are considered as basically the same are those that   _  . A) consumers don't care where to buy them B) consumers spend much time searching for C) meet similar needs of the consumers D) can be found in nearly every shop
Ans: C

Ques: It is difficult for doctors to help a person with a damaged brain. Without enough blood, the brain lives for only three to five minutes. More often the doctors can't fix the damage. Sometimes they are afraid to try something to help because it is dangerous to work on the brain. The doctors might make the person worse if he operates on the brain. Dr. Robert White, a famous professor and doctor, thinks he knows a way to help. He thinks doctors should make the brain very cold. If it is very cold, the brain can live without blood for 30 minutes. This gives the doctor a longer time to do something for the brain. Dr. White tried his idea on 13 monkeys. First he taught them to do different jobs, and then he operated on them. He made the monkeys' blood go through a machine. The machine cooled the blood. Then the machine sent the blood back to the monkeys' brains. When the brain's temperature was 10degC, Dr. White stopped the blood to the brain. After 30 minutes he turned the blood back on. He warmed the blood again. After their operations the monkeys were like they had been before. They were healthy and busy. Each one could still do the jobs the doctor had taught them. The biggest difficulty in operating on the damaged brain is that  _  . A) the time is too short for doctors B) the patients are often too nervous C) the damage is extremely hard to fix D) the blood-cooling machine might break down
