The Public Health System
One of the biggest changes since 1990 is the degree to which bioterrorism has become a public health priority.Although there had long been concern about vulnerability to biowarfare and bioterrorism the anthrax episode in the fall of 2001 made it clear that the concern is no longer theoretical.Until very recently, the important role of public health at the frontlines of bioterrorism preparedness was unrecognized.Although concern about emerging infections has helped stimulate funding for the chronically under-appreciated public health system, the threat of bioterrorism motivated the first real infusion of new money into public health in
decades.
Many of the capabilities needed to defend against bioterrorism are the same: as those needed to combat natural emerging infections.In both instance, the problem is an unexpected outbreak of infectious disease, of which the first indication is likely to be sick people in emergency rooms or clinics.Indeed, as with the anthrax attacks, the public health and medical responses may be under way before the true nature of the outbreak is recognized. Public health and the interface with the health care system are therefore key elements in any effective response to bioterrorism.
Whether the biggest threat is natural or engineered much remains to be done.Efforts to strengthen surveillance and response worldwide and to improve communication must be accelerated and sustained.Further,we have only scratched the surface in terms of understanding the ecology of infectious diseases and developing strategies for regulating microbial traffic.We need tools for better predictive epidemiologic modeling when a new infection first appears and for better analysis of the factors that transfer pathogens across species.One encouraging development is the program in the ecology of infections diseases that was started a few years ago be the National Science Foundation in cooperation with NIH.
SARS is a good yardstick of our progress during the past 13 years.The syndrome was unusual because novel infections that spread from person to person are relatively rare.Once cases were finally reported, the public health response was vigorous.WHO warned health care providers, researchers rapidly identified a candidate virus, and prototype diagnostic tests quickly became available.The vast reach of the Internet was instrumental in sharing formation and coordinating activities worldwide.Despite these advances, SARS had already spread to many countries.In fact had the disease been as transmissible as influenza, it would have invaded virtually every country in the world by the time the public health response had begun.So what SARS tells us is that although we have come long way since 1990, we still have a long way to go.

A.the threat of bioterrorism is real rather than theoretical
B.the concern about bio-warfare and bioterrorism has been justified
C.the public health system plays an important role in fighting against bioterrorism

第6题
Owls and Larks（猫头鹰与云雀）
1. In this article, we lookat the importance of sleep for learning. Most healthy adults need eight of morehours of sleep. But why do we need sleep in the first place？ We need sleep forthe brain to get a chance to rebuild memories stored during the day andassociate these with previously learned things. If this process is interruptedby, say. the sound of an alarm clock, it may not be as effective. So if yoursleep is cut short by the alarm clock, how damaging is it？ The truth is thatit&39;s difficult to predict, as so much depends on how much sleep your bodyactually needs on that particular occasion.
2. The popular belief thatpeople are naturally either larks (early risers) or owls is false. The rea- sonwhy people tend to be one or the other has more to do with lifestyle, age, andpersonality. Many people who appear to be early birds may have just become sothrough habit, for example, parents with very young children. Teenagers can havedifficulty falling asleep until late at night and then they natu-rally haveproblems getting up the following morning.
3. The main reason why owlsare owls is that they tend to spend their time over a book, movie, or com-puter game till the early hours of the morning. They enjoy the quiet of thenight when they can pursue their passion. On the other hand, larks can makebetter use of early morning hours where they can study in quiet atthe time whentheir brains are most refreshed. So which is better for learning an owl&39;s or alark&39;s lifestyle？ The simple truth is that it is more complex than simply beingone or the other. Leading a well-balanced life in terms of work and play andsleeping enough to bring maximum&39; refreshment is probably th~ secret.
4. As for naps,experts oninsomnia (失眠) argue against taking naps, as these may keep people up at night. If yournap lasts only five minutes to half an hour and does not affect your ability tofall asleep in the night, it will probably help you be more alert in eveninghours. However, if you are hav- ing problems getting to sleep at night, it&39;snot only naps that you should avoid. Try not to drink a lot of alcohol, take nicotine(尼古丁) ,do mentally intense activities like preparingfor exams or doing ex- ercise in the evening. Some people swear that drinkingcoffee never stops them from sleeping like a log,whereas others will never gonear the stuff for fear of being awake all night. However, the best advice formost is to.avoid it in the evening, and if you drink coffee before a nap,remember you are likely to awaken as soon as the caffeine starts kicking in.
