A scientific panel convened by the World Health Organization recommended guidelines on Friday for doctors conducting clinical studies of SARS patients. The panel urged doctors to apply the guidelines in analyzing the masses of potentially useful information about various therapies that were collected in this year’s epidemic. Much of that information has not been published or analyzed.
“It is a matter of urgency to get better analysis and review,” said Dr. Simon Mardel, a WHO official who led the two-day meeting that ended on Friday. He said thousands of potential therapies and compounds had been tested so far as researchers try to determine treatments for SARS, or severe acute respiratory syndrome. “We recognize that having no treatment for SARS is hindering our ability to control an epidemic in so many ways.” He said.
In the epidemic earlier this year, various treatments, like drugs to fight the virus or strengthen the immune system, as well as traditional Chinese medicine, were delivered under emergency conditions, in widely different settings and countries to patients suffering from varying stages of the illness. Those conditions—
generally without standardized measurements or controlled situations—have made it hard to interpret results.
Standard supportive therapy like nursing, and in severe cases the use of mechanical respirators(呼吸器)to help patients breathe, is the mainstay(主要支持)of SARS care, and helped many patients survive. But doctors still do not know how best to treat SARS patients who have breathing difficulties. Dr. Mardel said. One method is invasive ventilation. A second method involves blowing oxygen into the lungs through a mask. Both carry the risk of transmitting the virus to hospital employees. Without proper analysis, the panel was unable to say definitively which treatment worked best, or which caused the most harm. “There is a lack of shared information,” Dr. Mardel said, noting that a lot of data have not been published. The panel also agreed on guidelines that would allow doctors to conduct quick and safe clinical trials, a process that generally takes years to complete. The world Health Organization, a United Nations agency did not release the guidelines. Dr. Mardel said they were flexible because no one knew where, when and in what setting SARS would return. Experts in many countries have already listed the treatments they want to test, and the health agency is leaving these decisions to individual nations.

In recent years, teachers of introductory courses in Asian American studies have been facing a dilemma nonexistent a few decades ago, when hardly any texts in that field were available. Today, excellent anthologies(文選)and other introductory texts exist, and books on individual Asian Americans are published almost weekly. Even professors who are experts in the field find it difficult to decide which of these to assign to students; non-experts who teach in related areas and are looking for writings for and by Asian American to include in survey courses are in an even worse position.
A complicating factor has been the continuing lack of specialized one-volume reference works on Asian Americans, such as biographical dictionaries or desktop encyclopedias. Such works would enable students taking Asian American studies courses (and professors in related fields) to look up basic information on Asian American individuals, institutions, history, and culture without having to wade through(費力的閱讀冗長或艱深的材料)mountains of primary source material. In addition, given such works. Asian American studies professors might feel more free to include more challenging Asian American material in their introductory reading lists, since good reference works allow students to acquire on their own the
background information necessary to interpret difficult or unfamiliar material.
1. The author is primarily concerned with ______.
A. responding to a criticism
B. describing a course of study
C. discussing a problem
D. evaluating a past course of action
2. The “dilemma”(Line 2, Para.1) can best be characterized as being caused by the necessity to make a choice when faced with a ______.
A. lack of acceptable alternatives
B. lack of strict standards for evaluating alternatives
C. preponderance of bad alternatives as compared to good
D. multitude of different alternatives
3. Biographical dictionaries and desktop encyclopedias are _____ A. primary source materials B. introductory texts C. excellent anthologies D. reference materials
4. Which of the following is implied about the introductory courses in Asian American studies a few decades ago?
A. The range of different textbooks that could be assigned for such courses was extremely limited
B. The texts assigned as readings in such courses were often not very challenging for students
C. Students often complained about the texts assigned to them in such courses
D. Such courses were offered only at schools whose libraries were rich in primary sources
5. According to the passage, the existence of good one-volume reference works about Asian Americans could result in ______.
A. increased agreement among professors of Asian American studies regarding the quality of the sources available in their field
B. an increase in the number of students sighing up for introductory courses in Asian American studies
C. increased accuracy in writings that concern Asian American history and culture
D. the inclusion of a wider range of Asian American material in introductory reading lists in Asian
