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 become more dangerous over time．When a new type of a common virus changes，it may be able to get past the body’s immune(免疫的)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．
The situation is more serious today because ．
A．people travel more B．people don’t eat healthy food
C．there aren’t enough hospitals D．scientists can’t find a cure
From this passage we know ．
A．bird flu will surely spread to human beings in the next few years．
B．a virus changes and become less dangerous over time．
C．SARS is 1ikely to come again in some years．
D．poor areas usually suffers more from new diseases than rich areas．
The possible title of this passage is
A．The Work of WHO
B．Scientists Are Working Hard on Drugs for Diseases
C．What Is a Virus
D．Virus Changes and Causes New Diseases Over Time

The search for life in the universe took a step forward last month with the opening of the Allen Telescope Array(艾伦望远镜阵列) 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.

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 (通货膨胀率) 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(制造业). 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(石油禁运), 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.
