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

D．will be fully made use of and become the fridge of the future

73．Which of the following is TRUE according to the text?

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.

74．We can learn from the text that the prototype completed _______.

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

      and we’ll finish the work ahead of time.

C．Starting an hour earlierD．Started an hour earlier

“Hurry, Mommy! Let’s go trick-or-treating!” My daughter waited by the door in her pink princess skirt while I prayed in the living room. Usually I liked taking her out on Halloween, but this year I was sad. I was worried about my mother, who was in China on vacation. I got a call that afternoon that she had slipped and fallen on the hard floor of her hotel and broken her leg. She was taken to a hospital in Beijing. Mom was nervous because she couldn’t understand any of the doctors. If only I could do something to help her!
I knew I couldn’t let my worries spoil my daughter’s fun. There was nothing I could do for Mom except pray, I thought. We left the house and went down the block. I was so upset that I hardly took notice of the kids around me. There came the man to whose son I’d once given piano lessons. “Hello there,” I said, greeting him and the boy at his side.
“Hello,” the father answered. “Having fun?”“I’m trying,” I said. “Why, what’s wrong?” he asked. I told him the whole story. “My mother, in China, broke her leg and didn’t understand any of the doctors. And I’m too far away to do anything!” I said.
He raised his eyebrows. “Beijing, you said?” he asked. I nodded. He smiled. “Believe it or not, my sister is a doctor at an English-speaking hospital there. If you want, I’ll make a call right away and we’ll try and get your mom transferred (转移).”
A few days later I sat in the living room with my daughter as she finished the last of the candy. “Mommy, how far away is China?” she asked. “Not as far as I thought,” I said.
