The world hash’t seen a pandemic(流行疾病)in 4 1 years,when the”Hong Kong”flu crossed the globe and killed about one million people worldwide.If H1N1 flu(甲型流感)reaches pandemic levels,what would happen next?

       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.

College libraries are designed primarily for research and study.To explain its use, let us choose a research topic and follow the step-by-step procedure of looking up the material for the paper.

         Suppose your assignment is to write a paper on a novel called “The Sun Also Rises” by American writer Hemingway.The first step is to go to the main catalog.Many small drawers on the large wooden cabinets are lined up in alphabetical(字母的) order.Each of the drawers contains hundreds of alphabetical ordered cards.These cards are printed references to all material available in the library.Title cards are cataloged (为…编目录 ) by the first word of the book title, leaving out the articles like “a”, “an” and “the”.And then you get the cards for the books you need.On the upper left corner of each card is the call number.This is the numerical code that shows where the book is located in the library.The library has open and closed stacks.If your book is on the open stacks, you can go to the open-stack room, and according to the call number find it out by yourself.There are only about 30,000 books on open stacks, while most of the 800,000 books in our library are kept in closed stacks, which are accessible only to teachers and graduate students.
