There are two basic methods of conserving(保护) the natural environment．One is alternative technology in which techniques (such as windmills and solar energy) must be found for providing power．The other is to try to minimize the effects of modern technology by the more efficient use of materials and more effective pollution control．There comes a point when the quality of life can no longer be improved because of the high population density(密度) and the largely unsuccessful at tempts to meet its demands.

    Present energy policies of the western world are considering new energy sources to meet the demands of a growing population．The main sources used have been oil, gas, and coal- which are in limited supply- and nuclear power, which has problems concerning radioactive waste storage．Wind and solar energy are alternative possibilities, but only solar energy is likely to become a main power source for many countries.

    Many of the materials used daily in a technological society are destined(注定) to be discarded, Rags, paper, metal, glass, and plastics are all substances that could be recycled or reused．Research is being done to determine methods of separating useful products from industrial and domestic waste.

    The processing of sewage requires considerable amounts of electricity．Many sewage treatment plants in the U.S．have become self-sufficient by using the methane gas(沼气) given off by sewage．This is collected in gas holders and burned to produce heat and create electricity．The solid waste itself is often used for soil enrichment.

1．Modern technology is harmful to the natural environment because ________

A．of industrial pollutants.

B．it has become too expensive.

C．it has become too complicated.

D．it consumes all natural resources.

2．Alternative technology suggests that ________

A．new ways be found to burn coal, oil and gas.

B．solar energy and wind power be considered.

C．new ways be found to store radioactive waste.

D．the present energy resources be fully used.

3．Methane gas in used to ________

A．conserve(保存) industrial residues (废料).

B．create recycled paper products.

C．provide electricity to process sewage.

D．treat with the raw sewage.

4．From the selection, we can determine that ________

A．conservation technology is a necessity.

B．nuclear power is the energy source of the future.

C．problems of energy conservation are not worldwide.

D．all the industrial and domestic wastes can be reused and recycled.

5．Processing sewage requires large quantities of ________

A．water.

B．electricity.

C．gas.

D．oil.

    Small stores often will deliver orders to your home．If you do not need this service, you will do better shopping at a large chain(连锁店)．The large chain markets offer more varieties and have better prices.

    For most people it is best to choose a store with good prices and stay with it．Store-hopping(逛街) for sales on certain foods may save you pennies, but it can be costly in time and gas.

    The meat, poultry(禽), and fish items in your menu usually cost the most．Studies show that one-third of the money spent on food goes for these items．To take advantage of the best buys at the meat counter, you need to be aware of the many cuts(切块) of meat that are available．Also, you must know how to use them in meals．Keep in mind that the economy of a cut depends on the amount of cooked lean meat it serves as well as its price per pound．Often the cut with a low price per pound is not the best buy．What counts (有价值) is the amount of lean meat and the number of servings(一份菜) it will provide．For example, a high-priced meat with little or no waste may be a better buy than a low-priced cut with a great deal of bone or fat．So when you visit the market, be a smart shopper and take time to make the right choice.

1．For foods you buy all the time, it is good to check different stores to find ________.

A．the freshest foods.

　　There are two factors (因素) which determine an individual's intelligence. The first is the sort of brain he is born with. Human brains differ greatly, some being more capable than others. But no matter how good a brain he has to begin with, an individual will have a low order of intelligence unless he has opportunities to learn. So the second factor is what happens to the individualthe sort of environment in which he is reared. If an individual is handicapped (妨碍，阻碍) environmentally, it is likely that his brain will fail to develop and he will never reach the level of intelligence of which he is capable.

　　The importance of environment in determining an individual's intelligence can be demonstrated (证实) by the case history of the identical twins, Peter and Mark. Being identical, the twins had identical brains at birth, and their growth processes were the same. When the twins were three months old, their parents died, and they were placed in separate foster homes (寄养). Peter was raised by parents of low intelligence in a community with poor educational opportunities. Mark was raised in the home of well-to-do parents who had been to college. He was read to as a child, sent to good schools, and given every opportunity to be stimulated intellectually. This environmental difference continued until the twins were in their late teens, when they were given tests to measure their intelligence. Peter's I.Q. was 125, twenty-five points higher than the average and fully forty points higher than his identical brother. Given equal opportunities, the twins, having identical brains, would have tested at about the same level.

1．The main idea of this passage is that ________.

[　　]

A．one human brain is quite different from another

B．the brain a person is born with is important in determining his intelligence

C．environment is important in determining a person's intelligence

D．persons having identical brains will have about the same intelligence

2．According to the passage, Mark's I.Q. is ________ lower than the average.

[　　]

3．This passage suggests that an individual's I.Q. ________.

[　　]

A．can be foretold at birth

B．stays the same throughout his life

C．can be increased by education

D．is determined by his childhood

　　In this game you are in a tank and the screen shows your view of the landscape outside. You gain points by shoot enemy tanks, super tanks, missiles and saucers.

　　Experts gain scores of around 150,000 points at this game. To get a high score you have to destroy twenty tanks as quickly as possible. After this the super tanks, missiles and saucers appear. These are worth far more points than the ordinary tanks. (The number of tanks you have to destroy before the super tanks appear varies on different machines.)

　　Try to approach an enemy tank from the side or the back, so it cannot shoot at you. Then, when you get close, turn and face it, line it up in your sights and fire before it turns to shoot at you. If you miss, quickly escape by moving out of the enemy's line of fire, you can then move around the enemy and come in from another side.

　　When a super tank appears, try to destroy it. Then wait safely behind an obstacle for a missile or flying saucer. The cubes are useful objects to hide behind as you can fire over them without exposing yourself to danger. The missiles will fly straight at you, but they are difficult to hit, so do not shoot at them until they are quite close. The saucers are much easier to hit, but do not chase them as you will be open to attack from enemy tanks.

　　You might think that“sodbusters”are tools that bust sod. You'd be almost right. Sodbusters, however, were actually people.

　　In the late 1800s, many people moved to the Midwest to settle on land that the United States government had offered for free. Upon arriving, the settlers found that there were no trees for building shelters. The ground, however, had a thick layer of knotted, matted roots below the grassy surface. This kind of soil is called sod.

　　The early settlers' cut the sod into large cubes. Then they used the cubes of sod to build their shelters. The settlers also had to break up the vast areas of hard sod so that they could farm the land

　　Have you ever imagined what it would have been like to go on an old-time western cattle drive?

　　The early cattle drives were long and hard－and sometimes even dangerous. They took place because Texas ranchers wanted to get their beef cattle to people in northern cities. Railroads used for carrying the cattle did not go all the way into Texas at that time, however. The ranchers decided to solve their problem by hiring workers, called cowhands, to take the cattle to the railroad stops in Missouri, Kansas, and Colorado.

　　The long cattle drives ended when the railroad lines were extended into Texas and other western lands.

　　The world's oldest man, 112-ear-ld Antonio Todde died on the Italian island of Sardinia. Todde made it into the Guinness Book of Records when he turned 112 last year and wore his crown of “The Oldest Living Man on Earth” with pride and a sense of humor.

　　Born in a tiny mountain village in 1889, the same year work on the Eiffel Tower was completed and baby Adolf Hitler took his first breath, Todde seldom left the village. He lived in the same house with his wife of 78 years, Maria Antonia, all his life.

　　He witnessed (见证) the two World Wars, a technological revolution and saw the world's population quadruple (四倍) but was untroubled by the passing of the years.

　　“His life was very simple but those 100 years, he lived them to the full,” said Mariolina, recalling how he liked to play cards with his friends and go for long walks.

　　Todde's life and that of his fellow islanders is the focus of a scientific study.

　　A remarkable number of Sardinia's 1.6 million people live through a century. Some 135 people per million live to see their 100th birthday.

　　Todde's own family seems a case in point-his tow daughters are 78 and 81 separately and his sister is 98．

　　The answer to the often-posed question of just how he managed it was simple for Antonio.

　　“Just love your brother and drink a good glass of red wine every day,”he was quoted (引证) as saying when he celebrated his 112th birthday last year.

　　Hong Kong comedian Sun Xing said he came to Shanghai to work for “his wife”. In fact, he came here to make new TV serials (连续剧).“People working with me are likely (可能的) to have a stomachache, for I am able to please them so much that they forget to eat.”Sun joked.

　　Sun has played the role of Master Shen in the TV serials“Fairly Wife”, and many Shanghainese have since known and liked him. Instead of giving his own name, he had Master Shen printed on name-card together with a cartoon of himself: a smiling face with dark glasses and very short hair.

　　Though he is a Hong Kong citizen, Sun is able to speak perfect putonghua. Born and brought up in Beijing, he moved to Hong Kong at ten. In 1986, he came out of 3,600 contestants (竞争者) in the competition for“Mr. TV” held by Hong Kong's Asian TV station. In recent years, Sun is living and trying to develop in Taiwan.

　　According to Sun, his understanding of stages performance comes from ten-year-long experience in work and life, though he has had no regular training in acting.“Life is hard for me. I have worked as a porter, waiter, postman, salesman.”Sun recalled.“At the age of 14, I was employed as an office boy in my mother's factory.” Once he was hurt by sulfuric acid (硫酸), but he showed no sign of pain, because he did not want to worry his mother. Having tasted various hardships, Sun learned how to find happiness in life.

　　Sun is not good-looking, but he is able to make all kinds of funny movements in front of the camera. That's why all directors agree that he is very special.

　　After the return of Hong Kong to the motherland, Sun planned to develop his stage work more in the mainland. Not long ago, He got in touch with Qiong Yao, a well-known Taiwan writer, to make a TV program for the mainland.

　　Football is the most popular game in England: one has only to go to one of the important matches to see this.

　　One of the most surprising things about football in England to a stranger is the great knowledge of the game which even the smallest boy seems to have. He can tell you the names of the players in most of the important teams. He has photos of them and knows the results of a large number of matches. He will tell you proudly who he expects will win the game, and his opinion is usually right.

　　Most schools in England take football seriouslymuch more seriously than all the other European schools, where lessons are the most important and games are left for private arrangements. In England, it is believed that education is not only a matter of filling a boy's mind with facts in a classroom, education also means character training; and one of the best ways of training character is by means of games, especially team games, where the boy has to learn work with others for his team instead of working selfishly for himself alone. The school therefore arranges games and matches for its pupils. Football is a good team game. It is good exercise for the body. It needs skills and a quick brain and it is cheap. As a result, it is the school favourite game in winter.
