The global energy crisis is approaching. What can we do? Here are some steps you can take.
Cooling puts the greatest stress on your summer energy bill and the power grid(电网). Just as t tune-up for your car can improve your gas mileage, a yearly tune-up of your heating and cooling system can improve efficiency and comfort. Clean or replaces filters monthly or as needed.
For central air conditioning systems and room air conditioners, look for the ENERGY STAR, the federal government’s symbol for energy efficiency. For central air, purchase the system with the highest possible Seasonal Energy Efficiency Raton. (SEER)
Use energy-efficient ceiling fans either alone or with air conditioning. Ceiling fans do a great job of circulating air. When used with air conditioning, fans allow you to raise the thermostat(恒温器) and cut costs. Ceiling fans cool people, not rooms, so before you leave; turn off the ceiling fan.
Let a programmable thermostat! “remember for you” to automatically adjust the indoor climate with your daily and weekend patterns to reduce cooling bills by up to 10 percent. You can come home to a comfortable house without wasting energy and cresting pollution all day while you are at work.
Try to make your home airtight enough to increase your comfort, make your home quieter and cleaner and reduce your cooling costs up to 20 percent.
Gut your air conditioning load, and reduce pollution by planting planting leafy trees around your home and fixing reflective bricks on your roof.
Close blinds or shades on south-and west-facing windows during the day, or fix shading equipment to avoid heat build-up.
Turn off everything not in use: lights, TVs, computers. And use fluorescent bulbs(荧光灯), which provide bright, warm light while using at least two-thirds less energy, producing 70 percent less heat and lasting up to 10 times longer than incandescent bulbs(白炽灯).
Drive the car that gets better gas mileage whenever possible if you own more than one vehicle. If you drive 12,500 miles a year, switching 10 percent of your trips from a car that gets 20 mils per gallon to one that gets 30 mpg will save you more than ￡65 per year.
Carpool. The average U.S. commuter(乘车上班族) could save about ￡260 a year by sharing cars twice a week with two people in a car that gets 20.1 mpg---assuming the three passengers share the cost of gas.

举一反三
Mr. Johns was given a piece of asbestos which had been found in Italy. He experimented with the material and then showed its surprising powers to his customers. After putting on a pair of asbestos gloves, which looked much like ordinary work gloves, he took red-hot coals from the fireplace and played with them in his hands. How astonished the customers were to discover that he was not burned at all. You can well imagine that he had increasing business in asbestos roofing materials. However, because it was very expensive to transport (carry) them from Italy to the United States, Mr. Johns sent out a young scientist to seek a source nearer home. This young man found great vein(岩脉), in the province of Quebec in Canada.
Ever since 1881 Quebec has led the world in the production of this unusual mineral, which is made up of magnesium, silicon, iron, and oxygen. When it is mined, the asbestos is heavy, just as you would expect a mineral to be. When it is separated, a strange thing happens; the rock breaks down into fine, soft, soapy fibres(纤维).
Scientists do not know why the rock can be separated easily into threads(线), but they have found thousands of uses of this fireproof material, of the so-called “cloth of stone”.
小题1:Which title best expresses the main idea of this passage?
| A．Asbestos mined in Canada | B．Fireproof matter |
| C．A “wonder” mineral | D．A new roofing material |
| A．going into roofing business | B．carrying asbestos from Italy |
| C．sending a trained scientist | D．showing the use of asbestos gloves |
| A．It is like thread. | B．It feels soapy. |
| C．It burns easily. | D．It is unusually heavy. |
| A．show the need for more scientists |
| B．compare asbestos with other minerals |
| C．increase the sales of asbestos |
| D．present facts about asbestos |
In the European universities of the Middle Ages, students who were working for advanced degrees had to discuss questions in their field of study with people who had made a special study of the subject. This custom exists today as part of the process of testing candidates (应试者) for the doctor’s degree.
Generally, however, modem examinations are written. The written examination, where all students are tested on the same questions, was probably not known until the nineteenth century. Perhaps it came into existence with the great increase in population and the development of modem industry. A room full of candidates for a state examination timed exactly by electric clocks and carefully watched over by managers, looks like a group of workers at an automobile factory. Certainly, during examinations teachers and students are expected to act like machines.
One type of test is sometimes called an “objective” test. It is intended to deal with facts, not personal opinions. To make up an objective test, the teacher writes a series (一系列)of questions, each of which has only one correct answer. Along with each question the teacher writes the correct answer and also three statements that look like answers to students who have not learned the material properly.
4. The main idea of Paragraph Three is that ________.
A. workers now take examinations B. the population has grown
C. there are only written exams today D. examinations are now written and timed
5. The kind of exams where students must select answers are
A. objective B. personal
C. spoken D. written
6. Modem industry must have developed ________.
A. around the 19th century B. before the Middle Ages
C. in Greece or Rome D. machines to take tests
7. It may be concluded that testing ________.
A. should test only opinions B. should always be written
C. is given only in factories D. has changed since the Middle Ages
If you do not use your arm or your legs for some time, they become weak; when you start using them again, they slowly become strong again. Everybody knows that. Yet many people do not seem to know that memory works in the same way. When someone says that he has a good memory, he really means that he keeps his memory in practice by using it. When someone else says that his memory is poor, he really means that he does not give it enough chance to become strong. If a friend says that his arms and legs are weak, we know that it is his own fault(过错). But if he tells us that he has a poor memory, many of us think that his parents are to blame(受责备), and few of us know that it is just his own fault. Have you ever found that some people can’t read or write but usually they have better memories? This is because they cannot read or write and they have to remember things; they cannot write down in a little notebook. They have to remember days, names, songs and stories; so their memory is the whole time being exercised. So if you want to have a good memory, learn from the people: Practice remembering.
1. The main reason for one is poor memory is that _______.
A. his father or mother may have a poor memory
B. He does not use his name or legs for some time
C. his memory is not often used
D. he can’t read or write
2. If you do not use your arms or legs for some time _______.
A. you can’t use them any more
B. they will become stronger
C. they become weak and won’t become strong until you use them again.
D. they will become neither stronger nor weaker
3. Which of the following is NOT true?
A. Your memory works in the same way as your arms or legs.
B. Your memory, like your arms or legs, becomes weak if you don’t give it enough chance for practice.
C. Don’t learn how to read and write if you want to have a better memory.
D. A good memory comes from more practice.
4. Some people can’t read or write, but they usually have better memories, because _______.
A. they have save much trouble B. they have saved much time to remember things
C. they have to use their memories all the time D. they can’t write everything in a little notebook
5. Which is the best title for this passage?
A. Don’t Stop Using Your Arms Or Legs B. How To Have a Good Memory
C. Strong Arms And Good Memories D. Learn From the People
While all my classmates seen to be crazy about a one-way ticket to Mars(火星), I’d rather say Mars is totally unsuitable for human existence. People won’t have enough food supplies there, and the terrible environment would make it impossible for them to live a long life. Besides, the journey won’t be safe. Can anybody explain to me just why people would go to Mars, never to return?
Steve Minear, UK
Here are the things you can think of: the desire to explore a foreign and unique environment, the excitement of being the first humans to open up a new world, the expectation of fame and glory…For scientists there is another reason. Their observations and research will probably lead to great scientific achievements.
Donal Trollop, Canada
There are already too many people on the Earth. I think that sometime before the end of the century, there will be a human colony(殖民地)on Mars. It will happen when people finally realize that tow-way trips to the red planet Mars are unnecessary. Most of the danger of space Flight is in the launches(发射) and landings. Cutting the trip home would therefore reduce the danger of accidents, save a lot of money, and open the way to building an everlasting human settlement on another world.
Enough supplies can be sent on ahead. And every two years more supplies and more people will needs, and Mars is far more pleasant than the other planets in the outer space.
Paul Davies. USA

DARPA, the Defense Advanced Research Projects Agency, organized the race as part of a push to develop robotic vehicles for future battlefields. But the Grand Challenge, as it was called, just proved how difficult it is to get a car to speed across an unfamiliar desert without human guidance. One had its brake lock up in the starting area. Another began by throwing itself onto a wall. Another got tied up by bushes near the road after 1.9 miles.
One turned upside down. One took off in entirely the wrong direction and had to be disabled by remote (远距离的) control. One went a little more than a mile and rushed into a fence; another managed to go for six miles but stuck on a rock. The “winner,” if there was any, reached 7.8 miles before it ran into a long, narrow hole, and the front wheels caught on fire.
“You get a lot of respect for natural abilities of the living things,” says Reinhold Behringer, who helped design two of the car-size vehicles for a company called Sci-Autonics. “Even ants (蚂蚁) can do all these tasks effortlessly . It’s very hard for us to put these abilities into our machines.”
The robotic vehicles, though with necessary modern equipment such as advanced computers and GPS guidance, had trouble figuring out fast enough the blocks ahead that a two-year-old human recognizes immediately, Sure, that very young child, who has just only learned to walk, may not think to wipe apple juice off her face, but she already knows that when there’s a cookie in the kitchen she has to climb up the table, and that when she gets to the cookie it will taste good. She is more advanced, even months old, than any machine humans have designed.
小题1:Watchers doubted if any of the vehicles could finish the race because .
| A．they did not have any human guidance |
| B．the road was not familiar to the drivers |
| C．the distance was too long for the vehicles |
| D．the prize money was unattractive to the drivers |
| A．raise money for producing more robotic vehicles |
| B．push the development of vehicle industry |
| C．train more people to drive in the desert |
| D．improve the vehicles for future wars |
| A．can do effortlessly whatever tasks living thing can |
| B．can take part in a race across 142 miles with a time limit |
| C．can show off their ability to turn themselves upside down |
| D．can move from place to place without being driven by human beings |
| A．about eight miles | B．six miles |
| C．almost two miles | D．about one mile |
| A．for a robotic vehicle to finish a 142-mile race without any difficulties |
| B．for a little child who has just learned to walk to reach the cookie on the table |
| C．for a robotic vehicle to deal with a simple problem that a little child can solve |
| D．for a little child to understand the importance of wiping apple juice off its face |
