d Gehman； chairman of the Columbia Accident Investigation Board。
Testifying before the Senate Commerce Committee； Gehman said this part of his inquiry was in its earliest stages； starting just 10 days ago。 But Gehman said he already has concluded it is “inconceivable” that NASA would have been unable or unwilling to attempt a rescue for astronauts in orbit if senior shuttle managers and administrators had known there was fatal damage to Columbia’s left wing。
Gehman told reporters after the hearing that answers to these important questions could have enormous impact； since they could place in a different context NASA’s decisions against more aggressively checking possible wing damage in the days before Columbia’s fatal return。
Investigators believe breakaway insulating foam damaged part of Columbia’s wing shortly after liftoff； allowing superheated air to penetrate the wing during its fiery reentry on Feb。1； melt it from inside。
Among those decisions was the choice by NASA’s senior shuttle managers and administrators to reject offers of satellite images of possible damage to Columbia’s left wing before the accident。 The subject dominated the early part of Wednesday’s hearing。
Gehman complained managers and administrators “missed signals” when they rejected those offers for images； a pointedly harsh assessment of the space agency’s inaction during the 16…day shuttle mission。
“We will attempt to pin this issue down in our report； but there were a number of bureaucratic and administrative missed signals here；” Gehman told senators。 “We’re not quite so happy with the process。”
The investigative board already had recommended that NASA push for better coordination between the space agency and military offices in charge of satellites and telescopes。 The U。S。 National Imagery and Mapping Agency in March agreed to regularly capture detailed satellite images of space shuttles in orbit。
Still； Gehman said it was unclear whether even images from America’s most sophisticated spy satellites might have detected on Columbia’s wing any damage； which Gehman said could have been as small as two inches square。 The precise capabilities of such satellites proved to be a sensitive topic during the Senate hearing。

Text 4
When a disease of epidemic proportions rips into the populace； scientists immediately get to work； trying to locate the source of the affliction and find ways to combat it。 Oftentimes； success is achieved； as medical science is able to isolate the parasite； germ or cell that causes the problem and finds ways to effectively kill or contain it。 In the most serious of cases； in which the entire population of a region or country may be at grave risk； it is deemed necessary to protect the entire population through vaccination； so as to safeguard lives and ensure that the disease will not spread。
The process of vaccination allows the patient’s body to develop immunity to the virus or disease so that； if it is encountered； one can ward it off naturally。 To accomplish this； a small weak or dead strain of the disease is actually injected into the patient in a controlled environment； so that his body’s immune system can learn to fight the invader properly。 Information on how to penetrate the disease’s defenses is transmitted to all elements of the patient’s immune system in a process that occurs naturally； in which genetic information is passed from cell to cell。 This makes sure that； should the patient later come into contact with the real problem； his body is well equipped and trained to deal with it； having already done so before。
There are dangers inherent in the process； however。 On occasion； even the weakened version of the disease contained in the vaccine proves too much for the body to handle； resulting in the immune system succumbing； and； therefore； the patient’s death。 Such is the case of the smallpox vaccine； designed to eradicate the smallpox epidemic that nearly wiped out the entire Native American population and killed massive numbers of settlers。 Approximately 1 in 10；000 people who receives the vaccine contract the smallpox disease from the vaccine itself and dies from it。 Thus； if the entire population of the United States were to receive the Smallpox Vaccine today； 3000 Americans would be left dead。
Fortunately； the smallpox virus was considered eradicated in the early 1970’s； ending the mandatory vaccination of all babies in America。 In the event of a re…introduction of the disease； however； mandatory vaccinations may resume； resulting in more unexpected deaths from vaccination。 The process； which is truly a mixed blessing； may indeed hide some hidden curses。
36。The best title for the text may be
＇A＇ “Vaccinations： A Blessing or A Curse。” ＇B＇ “Principles of Vaccinations。”
＇C＇ “Vaccines： Methods and Implications。” ＇D＇ “A Miracle Cure Under Attack。”
37。What does the example of the Smallpox Vaccine illustrate？
＇A＇ The possible negative outcome of administering vaccines。
＇B＇ The practical use of a vaccine to control an epidemic disease。
＇C＇ The effectiveness of vaccines in eradicating certain disease。
＇D＇ The method by which vaccines are employed against the disease。
38。The phrase “ward it off naturally” （Paragraph 2） most probably means
＇A＇ dispose of it naturally。 ＇B＇ fight it off with ease。
＇C＇ see to it reluctantly。 ＇D＇ split it up properly。
39。Which of the following is true according to the text？
＇A＇ Saving the majority would necessarily justify the death of the minority。
＇B＇ The immune system can be trained to fight weaker versions of a disease。
＇C＇ Mandatory vaccinations are indispensable to the survival of the populace。
＇D＇ The process of vaccination remains a mystery to be further resolved。
40。The purpose of the author in writing this passage is
＇A＇ to comment and criticize。 ＇B＇ to demonstrate and argue。
＇C＇ to interest and entertain。 ＇D＇ to explain and inform。

Directions：Read the following text carefully and then translate the underlined segments into Chinese。 Your translation should be written clearly on ANSWER SHEET 2。 （10 points）
The old adage of the title has a parallel in the scientific world “all research leads to biomedical advances”。 The fact that research in one discipline contributes to another is well understood by the scientific community。 It is not； however； so clear to the public or to public policy…makers。 （46） Because public support for funding of biomedical research is strong； the scientific community could build a more effective case for public support of all science by articulating how research in other disciplines benefits biological medicine。
The time is ripe to improve public appreciation of science。 A recent National Science Foundation survey suggested that Americans continue to support research expenditures。 In addition； public opinion polls indicate that scientists and science leaders enjoy enviably high public esteems。 （47） Instead of lamenting the lack of public understanding of science； we can work to enhance public appreciation of scientific research by showing how investigations are in many areas close…knit and contribute to biomedical advances。 A crucial task is to convey to the public； in easily understood terms； the specific benefits and the overall good that result from research in all areas of science。
Take； for example； agricultural research。 （48） On the surface； it may appear to have made few significant contributions to biomedical advances； except those directly related to human nutrition。 This view is incorrect； however。 In the case of nutrition； the connections between agricultural and biomedical research are best exemplified by the vitamin discoveries。 （49） At the turn of the century； when the concept of vitamins had not yet surfaced and nutrition as a scientific discipline did not exist； it was in a department of agricultural chemistry that the first true demonstration of vitamins was made。 Single…grain feeding experiments documented the roles of vitamins A and B。 The essential role of some minerals （iron and copper） was shown later； and these discoveries provided the basis of modern human nutrition research。
（50） Despite such direct links； however； it is the latest discoveries that have been made in agricultural research that reveal its true importance to biomedicine。 Life…saving antibiotics such as streptomycin were discovered in soil microorganisms。 The first embryo transplant was made in a dairy cow； and related research led to advances in the understanding of human reproduction。
