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.
【小题1】According to the passage, the thermostat is used to ______.

On numerous drives throughout my childhood, my mother would suddenly pull over the car to examine a flower by the side of the road or rescue a beetle (甲虫) from certain tragedy while I, in my late teens and early twenties, sat impatiently in the car.
Though Mother’s Day follows Earth Day, for me, they have always been related. My mom has been “green” since she became concerned about the environment. Part of this habit was born of thrift (节俭). Like her mother and her grandmother before her, Mom saves glass jars, empty cheese containers and re-uses her plastic bags.
Mom creates a kind of give-and-take relationship with wildlife in her yard. She knows to pick the apples on her trees a little early to fend off the bears and that if she leaves the bird feeders out at night, it’s likely they’ll be knocked down by a family of raccoons (浣熊). Spiders that make their way into the house are captured (捕获) in a juice glass and set loose in the garden.
I try to teach my children that looking out for the environment starts with being aware of the environment. On busy streets, we look for spent (开败的) dandelions (蒲公英) to parachute; we say hello to neighborhood cats and pick up plastic cups and paper bags. This teaching comes easily, I realize, because I was taught so well by example. Mom didn’t need to lecture; she didn’t need to beat a drum to change the world. She simply slowed down enough to enjoy living in it and with that joy came compassion and an instinct (本能) for preservation.
I am slowing down and it isn’t because of the weight of my nearly forty years on the planet, it is out of my concern for the planet itself. I’ve begun to save glass jars and re-use packing envelopes. I pause in my daily tasks to watch the squirrels race each other through the palm (棕榈树) leaves above my porch (门廊).
Last summer, in the company of my son and daughter, I planted tomatoes in my yard. With the heat of August around me, I ate the first while sitting on my low wall with dirt on my hands. Warm from the sun, it burst on my tongue with a sweetness I immediately wanted to share with my mom.

What kind of car will we be driving in 2010? Rather different from the type we know today, with the next 20 years bringing greater change than the past 50．The people who will be designing the models of tomorrow believe that environmental problems may well accelerate the pace of the car’s development. Today they are students on the transport design course at London’s Royal College of Art.
Their vision is of a machine with three wheels instead of four, electrically powered, environmentally clean, and able to drive itself along “intelligent” roads equipped with built-in power supplies. Future cars will pick up their fuel during long journeys from a power source built into the road, or store it in small quantities for travelling in the city.
Instead of today’s seating arrangements—two in front, two or three behind, all facing forward--- the 2010 car will have a versatile interior with adults and children in a family circle.
This view of the future car is based on a much more sophisticated road system, with strips built into motorways to supply power to vehicles passing along them, cars will not need drivers, because computers will provide safe driving control and route finding. All the driver will have to do is say where to go and the computer will do the rest. It will become impossible for cars to crash into one another. The technology already exists for the car to become a true automobile.
71．What kind of car will we be driving in 2010?
A．Three wheeled.                B．Electrically powered.
C．With a versatile seating arrangement   D．All of the above.
72．How long will a volunteer be required to spend?
A．A few hours every day.                B．A couple of hours each day.
C．One or two hours every two weeks.     D．A few days per week.
73．What does the word “versatile” in Paragraph 3 mean?
A．having many different kinds of skill
B．easily able to change from one direction to another
C．easily able to change from one kind of activity to another
D．having many different uses
74．In paragraph 4 “with strips built into motorways to supply power to vehicles passing along them” means “there are many ____”.
A．traffic lights to control the speed of future cars
B．street posts to indicate directions for drivers
C．power sources along the street are able to supply power to automobiles
D．stop marks along the street to stop cars
75．What is the main idea of the passage?
A．Future cars are completely different from the automobiles we know today.
B．The design of future cars will be more sophisticated.
C．Because of the new type of cars, our future environment will become cleaner.
D．The road system will become more sophisticated than it is today.

When something goes wrong, it can be very satisfying to say, "Well, it's so-and-so's fault. "or "I know I'm late, but it's not my fault; the car broke down. " It is probably not your fault, but once you form the habit of blaming somebody or something else for a bad situation, you are a loser. You have no power and could do nothing that helps change the situation. However, you can have great power over what happens to you if you stop focusing on whom to blame and start focusing on how to remedy the situation. This is the winner's key to success.
Winners are great at overcoming problems. For example, if you were late because your car broke down, maybe you need to have your car examined more regularly. Or, you might start to carry along with you the useful phone numbers, so you could call for help when in need. For another example, if your colleague causes you problems on the job for lack of responsibility or ability, find ways of dealing with his irresponsibility or inability rather than simply blame the person. Ask to work with a different person, or don't rely on this person. You should accept that the person is not reliable and find creative ways to work successfully regardless of how your colleague fails to do his job well.
This is what being a winner is all about-creatively using your skills and talents so that you are successful no matter what happens. Winners don't have fewer problems in their lives; they have just as many difficult situations to face as anybody else. They are just better at seeing those problems as challenges and opportunities to develop their own talents. So, stop focusing on "whose fault it is." Once you are confident about your power over bad situations, problems are just stepping stones for success.
【小题1】According to the passage, winners ______.

Music is an international language. The songs that are sung or played by instruments are beautiful to all people everywhere.
Popular music in America is what every student likes. Students carry small radios with earphones and listen to music before class, after class, and at lunch. Students with cars buy large speakers and play the music loudly as they drive on the streets.
Adult drivers listen to music on the car radio as they drive to work. They also listen to the news about sports, the weather, politics, and activities of the American people. Most of the radio broadcast is music.
Pop or popular music singers make much money. They make a CD or tape which radio stations use in every state. Once the popular singer is heard throughout the country, young people buy his or her tapes. Some of the money from these tapes comes to the singer. Wherever the singer goes, all the young people want to meet him or her. Now the singer has become a national star. 
There are other kinds of music that are important to Americans. One is called folk music. It tells stories about the common life of Americans. Another is called western or country music. This was started by cowboys who would sing at night to the cows they were watching. Today, any music about country life and the love between a country boy and his girl is called western or country music.
Serious music for the concert halls is called classical music. Music for instruments is called orchestra music (管弦乐), such as the symphonies (交响乐) of Beethoven. There is opera (歌剧) for singers. There is ballet (芭蕾舞剧) for dancers like the story of Liang Shanbo and Zhu Yingtai in China?
