阅读材料，回答下面的题目。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 indecades.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.The main idea expressed in the first paragraph is that__________.
bioterrorism is an engineered threat to human beings

根据以下材料回答下面的题目：Academic MobilityScholars and students have always been great travelers. "Academic mobility" is now often stated as a fundamental necessity for economic and social progress in the world, but it is certainly nothing new. Serious students were always ready to go abroad in search of the most stimulating teachers and the most famous academies; in search of the purest philosophy, the most effective medicine, the likeliest road to gold.Mobility of this kind means also mobility of ideas, their transference across frontiers, their simultaneous impact upon many groups of people. The point of learning is to share it, whether with students or with colleagues; one presumes that only eccentrics have an interest in being credited with a startling discovery, or a new technique. It must also have been reassured to know that other people in other parts of the world were about to make the same discovery or were thinking along the same lines, and that one was not quite alone, confronted by inquisition, ridicule or neglect.In the twentieth century, and particularly in the last twenty years, the old footpaths of the wandering scholars have become vast highways. The vehicle which has made this possible has of course been the aero plane, making contact between scholars even in most distant places immediately feasible, and providing for the very rapid transmission of knowledge. Apart from the vehicle itself, it is fairly easy to identify the main factors which have brought about the recent explosion in academic movement. Some of these are purely quantitative and require no further mention: there are far more centers of leaming, and a far greater number of scholars and students.In addition, one must recognize the very considerable multiplication of disciplines, particularly in the sciences, which by widening the total area of advanced studies has produced an enormous number of specialists whose particular interests ale precisely defined. These people would work in some isolation if they were not able to keep in touch with similar isolated groups in other countries.It can be concluded from the passage that "academic mobility"__________
scholars can meet each other more easily
