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.

Even with little exposure to cultural standards of beauty, “infants treat attractive faces as distinctive regardless of the sex, age a nd race of the stimulus(刺激物) faces,” write psychologist Judith H.Langlois and her colleagues in the January DEVELOPMENTAL PSYCHOLOGY.
In their experiment, 5 healthy 6-month-old infants from middle-class families viewed slides showing eight pairs of white male faces and eight pairs of white female faces. Each pair, displayed for 10 seconds, consisted of one attractive and one unattractive face, as previously judged by a group of male and female college students. An experimenter viewed the young participants on a video monitor and recorded the direction and duration of each infant’s gaze.
The 35 boys and 25 girls looked longer at both male and female faces judged as attractive, the researchers found.
Their second study of 6-month-old involved 15 boys and 25 girls, mostly white, who saw eight pairs of slides showing an attractive and an unattractive black female, as previously judged by both white and black college students. Again, the babies looked much longer at attractive faces.
Finally, 19 boys and 20 girls, all 6 months old and almost all of them white, viewed eight pairs of slides showing the faces of 3-month-old boys and girls previously rated as attractive or unattractive by college students. Attractive baby faces drew signficantly longer looks, the psychologists report.
Further studies must explore whether infants take attractive faces as “best examples” of a face, the investigators claim Langlois and a coworker recently reported that attractive faces may possess features that approximate the mathematical average of all faces in particular population.
1.What was found in the first study?
A.Male infants looked longer only at female ones.
B.Females looked more attractive than males.
C.Sixty 6?month?old babies looked longer at the attractive faces, male or female.

2.In the last paragraph, the writer implies that .
A.Langlois and her partners will stop their experiments they accomplished a lot
B.Langlois and her partners will focus on the other fields of infants
C.Langlois and her partners have achieved success in studying the infants’ mind
D.Langlois and her partners have found a more interesting field
3.What can be inferred from the passage?
A.All babies, white or black, tend to share with the college students the preference for attractive faces.
B.White babies prefer white faces to black ones.
C.Babies tend to get interested in the attractive faces of the opposite sex.
D.Beauty has something to do with a person’s age, race and sex
4.The title that best expresses the main idea is .
