题目列表(包括答案和解析)

The outbreak of SARS in 2003 rang alarm bells as potential pandemics．Although it jumped the”animal-to·human”barrier，neither disease changed enough to enable human-to．Human infection．Strictly speaking，SARS did not become pandemics because it was too good at killing their hosts．For a pandemic，it needs to be able to maintain human-to．human contact without killing its host off．

”H1N1 flu is already a man-to-man disease，which makes it much more difficult to manage．

And H1N1 flu appears much more infectious than SARS．

But the WHO warns，it cannot say whether or not it will indeed cause a pandemic．According to experts，here’s what the world might see if there is another pandemic，based on past experience．

The disease would skip from city to city over an 18-to-24 month period，infecting more than a third of the population．World health Organization officials believe as many as 1．5 billion people around the globe would seek medical care and nearly 30 million would seek hospitalization．Based on the last pandemic and current world population，as many as 7 million people could die．Hospitals will become overcrowded；schools will close；businesses will close；airports will be empty．Business will become very bad，as people avoid as much social contact as possible．

Health facilities will become overrun with patients and there would be less-than-adequate staffing，as medical health professionals fall ill themselves and that would result in higher deaths．

The very young and very old will likely be the most susceptible（易受感染的）to the illness．Experts warn，much is still unknown about the current H1N1 flu virus and its severity and it is too early to say whether it will lead to a pandemic．Right now，the focus is on finding answers and controlling the spread．

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
