单选题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 under-standing the ecology of infections 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 infectious 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 Interact was instrumental in sharing in 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.

单选题Cheour doesn't know how babies accomplish this night - learning, but she suspects that the special ability might indicate that unlike adults, babies don't "turn off" their cerebral cortex while they sleep. The skill probably fades in the course of the first year of life, she adds—so forget the idea that you can pick up tricky French vowels as an adult just by slipping a language tape under your pillow. But while it may not help grown -ups, Cheour is hoping to use the sleeping hours to give remedial help to babies who are genetically at risk of language disorders. What can scientists probably use the new discovery to do.9A. To help adult pick up a new language more easily.B. To help babies learn their mother tongue more quickly.C. To help babies genetically at risk of language disorders.D. To help babies recover from genetic defects.

单选题The Sea What do you know about the sea? We know that it looks very pretty when the sun is shining on it. We also know that it can be very rough when there is a strong wind. What other things do we know about it? The first thing—to remember is that the sea is very big. When you look at the map of the world you will find there is more water than land. The sea covers three quarters of the world. The sea is also very deep in some places. It is not deep everywhere. Some parts of the sea are very shallow. But in some places the depth of the sea is very great. There is one spot, near Japan, where the sea is nearly 11 kilometres deep! The highest mountain in the world is about 9 kilometres high. If that mountain were put into the sea at that place, there would be 2 kilometres of water above it! What a deep place! If you have swum in the sea, you know that it is salty. You can taste the salt. Rivers, which flow into the sea, carry salt from the land into the sea. Some parts of the sea are more salty than other parts. There is one sea, called the Dead Sea, which is very salty. It is so salty that swimmers cannot sink! Fish cannot live in the Dead Sea! In most parts of the sea, there are plenty of fishes and plants. Some live near the top of the sea. Others live deep down. There are also millions of tiny living things that float in the sea. These floating things are so small that it is hard to see them. Many fish live by eating these. The sea can be very cold. Divers, who go deep down in the sea, know this. On the top the water may be warm. When the diver goes downwards, the sea becomes colder and colder. Another thing happens. When the diver goes deeper, the water above presses down on him. It squeezes him. Then the diver has to wear clothes made of metal. But he cannot go very deep. Some people who wanted to go very deep used a very strong diving ship! They went down to the deepest part of the sea in it. They went down to a depth of eleven kilometres!

单选题Outside-the-classroom Learning Makes a Big Difference Putting a bunch of college students in charge of a $300,000 Dance Marathon, fundraiser surely sounds a bit risky? When you consider the fact that the money is supposed to be given to children in need of medical care, you might call the idea crazy. Most student leaders don't want to spend a large amount of time on something they care little about, said 22-year-old University of Florida student Darren Heitner. He was the Dance Marathon's operations officer for two years. Yvonne Fangmeyer, director of the student organization office at the University of Wisconsin, conducted a survey in February of students involved in campus organizations. She said the desire for friendship was the most frequently cited reason for joining. At large universities like Fangmeyer's, which has more than 40,000 students, the students first of all want to find a way to "belong in their own comer of campus". Katie Rowley, a Wisconsin senior, confirms the survey's findings. "I wanted to make the campus feel smaller by joining an organization where I could not only get involved on campus but also find a group of friends." All of this talk of friendship, however, does not mean that students aren't thinking about their resumes. "I think that a lot of people do join to 'fatten up their resume'," said Heitner. "At the beginning of my college career, I joined a few of these organizations, hoping to get a start in my leadership roles." But without passion student leaders can have a difficult time trying to weather the storms that come. For example, in April, several student organizations at Wisconsin teamed up for an event designed to educate students about homelessness and poverty. Student leaders had to face the problem of solving disagreements, moving the event because of rainy weather, and dealing with the university's complicated bureaucracy. "Outside-of the classroom learning really makes a big difference," Fangmeyer said.

单选题 {{B}}Death penalty{{/B}} With the possible exception of equal rights, perhaps the most controversial issue across the united States today is the death penalty. Many argue that it is an effective deterrent to murder, while others maintain there is no convincing evidence that the death penalty reduces the number of murders. The principal argument advanced by those opposed to the death penalty, basically, is that it is cruel and inhuman punishment, that it is the mark of a brutal society, and finally that it is of questionable effectiveness as a deterrent to crime anyway. In our opinion, the death penalty is a necessary evil. Throughout recorded history there have always been those extreme individuals in every society who were capable of terribly violent crimes such as murder. But some are more extreme than others. For example, it is one thing to take the life of another in a fit of blind rage, but quite another to coldly plot and carry out the murder of another one or more people in the style of a butcher. Thus, murder, like all other crimes, is a matter of relative degree. While it could be argued with some conviction that the criminal in the first instance should be merely isolated from society, such should not be the fate of the latter type murderer. The value of the death penalty as a deterrent to crime may be open to debate. But the overwhelming majority of citizens believe that the death penalty protects them. Their belief is reinforced by evidence which shows that the death penalty deters murder. For example, from 1954 to 1963, when the death penalty was consistently imposed in California, the murder rate remained between three and four murders for each 100,000 population, Since 1964 the death penalty has been imposed only once, and the murder rate has risen to 10.4 murders for each 100,000 population. The sharp climb in the state's murder rate, which began when executions stopped, is no coincidence. It is convincing evidence that the death penalty does deter many murderers. If the bill reestablishing the death penalty is vetoed, innocent people will be murdered—some whose lives may have been saved if the death penalty were in effect. This is literally a life or death matter. The lives of thousands of innocent people must be protected.
