An early invention by Albert Einstein has been rebuilt by scientists at Oxford University. They are trying to develop an environmentally friendly refrigerator that runs without electricity.

We all know that modern fridges cause damage to the environment. They work by using a kind of man-made greenhouse gas called Freon (氟里昂), which is far more damaging than carbon dioxide.

Now Malcolm McCulloch, an electrical engineer at Oxford, is leading a three-year project to develop appliances that can be used in places without electricity.

His team has completed a prototype (样机) of a fridge patented in 1930 by Einstein. It used only pressurized gases to keep things cold. The design was partly used in the first refrigerators, but the technology was dropped when more efficient compressors (压缩机) became popular in the 1950s. That meant a switch to using Freon.

Einstein’s idea uses butane (丁烷) and water and takes advantage of the fact that liquids boil at lower temperatures, when the air pressure around them is lower.

“If you go to the top of Mount Qomolangma, water boils at a much lower temperature than it does when you’re at sea level and that’s because the pressure is much lower up there,” said McCulloch.At one side is the evaporator (蒸发器), a bottle that contains liquid butane. “If you introduce a new vapor above the butane, the liquid boiling temperature decreases and, as it boils off, it takes energy from the surroundings to do so,” says McCulloch. “That’s what makes it cold.”

The gas fridges based on Einstein’s design were replaced by Freon-compressor fridges partly because Einstein’s design was not very efficient. But McCulloch thinks that by changing the design and replacing the types of gases used it will be possible to quadruple (翻两番) the efficiency.

However, McCulloch’s fridge is still in its early stages. “It’s very much a prototype,” he said. “Give us another month and we'll have it working.”

72．According to the passage, an early invention by Albert Einstein _______.

A．has been rediscovered because it costs much less and works more efficiently

B．is being redesigned because it could be used in places without electricity

C．has just been found to be energy-saving and environmentally friendly

A．Freon was used in fridges long before the 1950s.

B．Freon is what makes current fridges big polluters.

C．McCulloch thinks he could improve Einstein's design by using other types of vapors.

D．The fridge Malcolm McCulloch and his team designed will be put into production soon.

A．changed the air pressure around it

B．was tested on the top of Mount Everest

C．increased the liquid boiling temperature

D．used only pressurized gases to keep things cold

75．McCulloch’s words in Paragraph 6 _____.

A．serve as an explanation for the principle behind Einstein’s fridge

B．give you the reason why Einstein’s fridge was not efficient

C．tell you how to take advantage of low air pressure

D．show you how Einstein’s fridge works

The quest for success always begins with a target. As Berra once said , ＂you get to be very careful if you don＇t know where you＇re going, because you might not get there.＂
Too many people wander through life like sleepwalkers. Each day they follow familiar routines, never asking, ＂What am I doing with my life?＂and they don＇t know what they＇re doing because they lack goals.
Goal-setting is a focus of the will to move in a certain direction. Begin with a clear conception of what you want. Write down your goals and date them---putting them into words clarifies them. Rather than concentrating on objects to acquire and possess, focus on fulfilling your desires to do, to produce, to contribute to goal-setting that yields the true sense of satisfaction we all need.
It’s important to visualize(想象)yourself accomplishing your goal. While losers visualize the penalties(不利) of failure, winners visualize the rewards of success. I’ve seen it among athletes, statistics contrasting air and highway safety, but it made no difference. I had read too many articles describing crash scenes and imagined these scenes vividly. I had programmed myself, without realizing it ,to stay off planes.
Then one summer I had the opportunity to fly on a private plane with friends to a resort; I didn’t want to miss out on a great vacation. So I spent two weeks imagining a smooth flight on a beautiful sunny day and an easy landing.
When the day arrived, I was eager to go . To everyone＇s surprise, I got on the plane and I loved every minute of it , and I still use the techniques I employed that day.
【小题1】According to the passage, if you want to be successful ,the first thing for you to do is to .

A．find the right methods	B．be careful about everything
C．know your ability	D．have a clear goal

【小题2】The problem with the author before he overcame his fear of air travel is that .

A．he didn’t know air travel is safer than highway travel

B．he couldn’t imagine himself accomplishing his goal

C．he read too much about plane crashes and tried to avoid flying

D．he wanted to take a private plane instead of a public one

【小题3】What would be the best title for this passage?

A．Defining Your Goal	B．Visualizing Reward of Success
C．Overcoming the Fear of Air Travel	D．Sleepwalking Through life

When you’re a preteen, a huge problem might be that you just have to have a new rock-rap CD, 1 your parents won’t give you the money for it. I thought life was so 2 when things like this happened-----until September 11, 2001.

I was in P.E. when the planes hit the World Trade Centre and the Pentagon. As soon as I got home and for weeks before, I saw the disaster 3 on TV. Seeing the innocent people running for their 4 as the debris(瓦砾) started coming down the fire and smoke rose out of the 5 brought tears to my eyes. I couldn’t help imagining what the people on the 6 and in the buildings were thinking and going through, not 7 what was going on. I admired the courage of the firefighters who rushed in and risked their own lives to 8 others. It tore my heart apart to watch the 9 looks on the faces of so many people who didn’t know if their loved ones were dead or alive while 10 in all the debris.

Then it 11 me: All my life I had thought mainly of myself. I had it easy in life and had been taking it all for granted.

A feeling of coldness 12 down my back, and I cried just thinking of the possibility that it could have easily 13 to my family. My mom or dad could have been killed like that, and I would never, ever see them again. I began to evaluate what a real 14 in life was.

This disaster 15 me that awful things can happen to anyone at any time. Now when my mom or dad or sister go somewhere, even if it’s just 16 the store, I try to remember to tell them that I love them because I know there is a 17 that I may never tell them that 18 .

Not getting a new CD is not going to 19 my life. I can live with those kinds of problems. But losing someone I love would 20 make my life miserable.
