In 2004,the World Health Organization,WHO,warned of a possible outbreak of another serious disease which may be even more deadly than SARS.The WHO believes that it is likely that bird flu will spread to human beings in the next few years.If it does,up to seven millions people could die from the disease.

Diseases like bird flu are caused by viruses,that is,tiny things which change and be come more dangerous over time.When a new type of a common virus changes,it may be able to get past the body’s immune system.If that happens,humans are in great danger until a cure or treatment becomes available.

There have always been viruses and people always get sick,of course,but as we saw with SARS,the situation is more difficult today.People travel more than ever before,which means that disease can spread quickly and across large areas——in fact the whole world.

Scientists are already working on drugs that will prevent or limit the effect of a new virus,but the process takes time.It is just as important to make sure that countries,especially poor countries,are prepared to deal with the disease。New disease usually affect poor areas the most,so we must help develop health care in all countries.

64.The situation is more serious today because           .

A.people travel more                                         B.people don’t eat health food

C.there aren’t enough hospitals                     D.scientists can’t find a cure

The search for life in the universe took a step forward last month with the opening of the Allen Telescope Array(艾倫望遠鏡陣列) in Hat Creek, California. The telescopes were partly made possible by a gift of twenty-five million dollars from Paul Allen. The total cost of the project is already fifty million dollars.
At present, there are 42 radio telescopes working at the Hat Creek observatory. The signals they receive are combined to create what is equal to a single, very large telescope. The telescope will be used to observe objects like exploding stars, black holes and other objects that are predicted but have not yet been observed. Seth Shostak of the SETI Institute says this is the first telescope whose main purpose is to search for signals from intelligent life in space. The SETI Institute is based in Mountain View, California. The organization supports the search for other life forms in the universe.
What makes the Allen Telescope Array unusual is that it can collect and study information from a wide area of the sky. In addition, the 42 telescopes can study information about several projects at the same time. That means studies of large areas of the sky can be made faster than ever before.
Some officials think the Allen Telescope Array will be completed in three more years. 350 individual radio telescopes are planned. The new abilities of the Allen Telescope Array will make searching for stars similar to the sun much faster.
An earlier search by SETI, Project Phoenix, studied about 800 stars to a distance of 240 light years. The project ended in 2004. With the Allen Telescope Array, astronomers hope to gather thousands of times more information in the search for life beyond our planet.
【小題1】The main purpose of the Allen Telescope Array is          .

A.to serve for the research of weather predication
B.to prepare for the wars against life from the universe
C.to search for signals from intelligent life in space
D.to observe exploding stars, black holes and other objects
【小題2】From this passage we know that         .
A.the 42 radio telescopes at Hat Creek observatory can work together
B.the total cost of the project came from Paul Allen
C.Hat Creek observatory can receive signals from all parts of the worm
D.Hat Creek observatory is operated by an American named Paul Allen
【小題3】Which of the following is TRUE according to this passage?
A.The Allen Telescope Array takes much more room than former telescopes.
B.The Allen Telescope Array is still being built at present in the United States.
C.Another 42 radio telescopes will be fixed in the Allen Telescope Array.
D.The SETI Institute is against the search for other life forms in the universes.
【小題4】With the help of the Allen Telescope Array,         .
A.a(chǎn)stronomers can gather more information than before from other planets
B.humans will have more chances to live on other planets than before
C.humans will be able to find more natural resources on other planets
D.scientists will be able to find more natural resources from other planets

Experts debunk Maya doomsday(末日) predictions -- But that hasn't stopped books, movies from cashing in.

If the ancient Maya and filmmaker Roland Emmerich are correct, the apocalypse(大災變) will happen very fast, maybe quicker than his new 2½-hour movie.

Predictions of global ruination are rippling around the globe with seismic(地震的) force, all loosely based on a 5,000-year Maya calendar that ends Dec. 21, 2012. Countless Web sites and blogs anticipate(預料) the end of days, as do various New Age groups and would-be prophets(預言者) offering guidance and how-to tips. On Amazon.com , you can read hundreds of book titles combining the year 2012 with terms such as “apocalypse,” “catastrophe” and “end of the world.”

As always, doomsday sells — and a lot of people are buying it.

“There's the psychobabble(心理囈語) aspect,” said Robert Epstein, former editor of Psychology Today magazine and a lecturer at the University of California San Diego. “It's the Sigmund Freud/death wish idea: People glom onto(對…感興趣) doomsday predictions because there's some small part of them that wants to die, and die spectacularly(壯觀的). I don't believe it, but it's one way to look at this.”

It's Emmerich's way. The German director specializes in wreaking havoc on an epic scale, from climatic cataclysm in 2004's “The Day After Tomorrow” to angry aliens and reptiles in “Independence Day” and “Godzilla.”  In “2012,” he finishes the job.

The digitized disasters of “2012” are oversized, overwrought and sometimes literally over the top, as when a humongous tsunami washes over the Himalayan mountains, whose average height exceeds 20,000 feet. Meanwhile in Los Angeles, a 10.5-magnitude earthquake — a temblor at least 30 times more powerful than any real quake ever recorded — yanks the city apart like a giant zipper, sending chunks sliding into the Pacific Ocean.

That's not physically possible, of course. Nor is a 10.5-magnitude quake, said Thomas Rockwell, a geologist at San Diego State University. To generate that much energy, “you'd need a rupture that extends all around the planet.”

All of that other stuff “is pure Hollywood bunk,” said Bernard Jackson at the UCSD Center for Astrophysics and Space Sciences.

Entertaining, though, unless you happen to believe the Maya really predicted the end of the world. They didn't, said Geoff Braswell, a UCSD anthropologist. The long-count calendar doesn't signal the end of anything except the end of that particular calendar. “It's just like a car odometer. Unfortunately, hardly anybody reads ancient Mayan. Modern media hype(騙局), on the other hand, is almost inescapable.

Nicholas Christenfeld, a professor of psychology at UCSD, suggests a more elemental human need. Being swallowed by the Earth or incinerated in a giant fireball “fits neatly with the idea that people want to believe there's a plan, that existence isn't random and pointless,” Christenfeld said.

“We all missed creation, but if we can bear witness at the other end, be part of some grand cosmic destruction, that gives life meaning,” he said. 

It helps, too, not to think very hard about the facts, said Lou Manza, a professor of psychology at Lebanon Valley College in Annville, Pa. “These claims have been around forever, and they have all been false, 100 percent wrong,” Manza said.

Of course, prognosticators(預言者, 占卜者) usually have an explanation for that, Christenfeld said.

“They might say it was a misinterpretation,” he said. “They got the date wrong. They might claim humanity acted in time to prevent the destruction. Or faith came to the rescue because people believed something bad was going to happen, it didn't have to happen.”

科目:高中英語 來源:2010-2011學年貴州省高三上學期第四次月考(四校聯(lián)考)英語卷 題型:閱讀理解

A couple of years ago, those who forecast that oil price would reach $ 100 a barrel were seen as doomsters. However, now some are predicting $ 200 a barrel.

Had economists been told that oil price would barely pause at $ 100 before reaching the recent peak of nearly $ 127, they would no doubt have forecast terrible economic consequences. But the global economy, though interrupted by the high price of energy, is still chugging along. Meanwhile, inflation has picked up, but the headline rates of inflation (通貨膨脹率) in most developed countries are nowhere near the levels seen in the 1970s and 1980s.

There are three explanations for the oil price’s unclear impact. The first is that nowadays developed economies are more efficient in their use of energy, thanks partly to the increased importance of service industries and the diminished role of manufacturing(制造業(yè)). According to the Energy Information Administration, the energy intensity of America’s GDP fell by 42% between 1980 and 2007.

A second theory is that the oil-price rise has been steady, not sudden, giving the economy time to adjust. Giovanni Serio of Goldman Sachs points out that in 1973 there was a severe supply shock because of the oil embargo(石油禁運), when the world had to cope with 10%-15% less crude almost overnight. Not this time.

The third explanation turns the argument on its head; rather than oil harming the global economy, it is global expansion that is driving up the price of oil.

The most important factor is the shift in favor of the developing economies. America has responded to high price in familiar fashion: UBS forecasts that demand will drop by 1.1% this year and will be no higher in 2010 than it was in 2004. But the demand from China and other emerging markets is more than offsetting(抵消) this shortfall.

1.What is the passage mainly talking about?

A.The prediction of economists.

B.The situation of economy

C.The increase of oil price

D.The American response to high price

2.How many explanations for the oil price’s impact are mentioned in the passage?

A.Two

B.Three

C.Four

D.Five

3.What can we conclude from the passage?

A.In USA, the demand for oil in 2010 will be very high.

B.In USA, the demand for oil in 2010 will be higher than it was in 2004.

C.In USA, the demand for oil in 2010 will be as high as it was in 2004.

D.In USA, the demand for oil in 2010 will be as low as it was in 2004.
