By 2012，the world may need to cope with as many as 50 million people who have fled their homeland，not for political or economic reasons but because the environment has been so badly changed that it cannot support life. The statement has been released by the United Nations to mark UN Disaster Reduction Day.
More people are made homeless by environmental disasters than by war，according to the research by the Red Cross. That reality is proved by the earthquake in Pakistan.
The widely publicized disaster has brought aid from the global community，according to Janos Bogardi，director of the United Nations University Institute for Environment and Human Security. “If we can move swiftly in and give them a new start where they are，then they may stay in the area. Otherwise，they become environmental refugees. Environmental­related migrations are most acute in Sub­Saharan Africa，but they also affect millions of people in Asia and India. Meanwhile，the United States is witnessing increased pressure from victims of mismanaged and worsening soil and water conditions in Mexico and Latin America.” he says. Janos Bogardi says these refugees suffer from the impact of gradual environmental change—global warming，sea level rise，air and water pollution and more intense storms，floods and droughts that degrade the land. This is a slow process，but unfortunately a process that is very difficult to go backwards once final damage is done.
Janos Bogardi says they are calling on the global community to recognize the serious situation of environmental refugees and to work together to lessen the impact of environmental disaster.

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.”

B．Freon is what makes current fridges big polluters.

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

【小题1】 According to the passage, an early invention by Albert Einstein _______.

IF you lived by the sea, you’d know that typhoons are frequent（频繁的）visitors during summer .They bring Strong winds, heavy rain and flooding（洪水）But most of the time, when people stay indoors, they’re just all right.

This is what the people in the Philippines used to believe – until they met the “super typhoon”, Haiyan. 

The typhoon hit the country on Nov 8, at around 5 am, when most people were still asleep. But being at home didn’t keep them safe, since few buildings remained standing once they were hit by wind as violent as 376 kilometers per hour, according to NBC News.

“This is at the top end of any tropical system that we’ve seen on our planet,” said Bryan Norcross, a weather scientist working for NBC. And so far, Haiyan has caused more than 3,600 deaths and left millions of people homeless.

.But where did Haiyan get its destructive power?

According to Brian McNoldy, a tropical weather expert at the University of Miami, US, Haiyan was so strong because “it had everything working for it”

“All typhoons feed off the warm ocean waters,” Colin Price, a weather researcher at Tel Aviv University in Israel, told National Geographic. Tropical storms are like giant engines（发动机），powered by the heat transferred（传导）from the ocean waters to the air above. However, because of climate change, the oceans have been warming up in recent decades. “Warmer oceans will result in more intense（强烈的）storms，” Price said.

Also, Haiyan started near the equator（赤道），where it was able to pick up more heat before heading to the Philippines. Moreover, the route（路线）it traveled was mostly along open ocean, which means no land prevented it from gathering steam（水蒸气）．

In addition, there happened to be very little “wind shear（风切变）in the area this time. Wind shear is a sudden change in wind speed or direction, which can tear apart developing storms. This is like when you stir（搅动） a glass of water with a chopstick: a swirl（漩涡）will form, ‘but if you move the chopstick in the opposite direction, the swirl will quickly disappear.”

“When all those things align in a certain way, you’re going to get something like‘Haiyan’.”Jim Kossin, a scientist with the US National Oceanic and Atmospheric Administration, told National Geographic.
