The first and the last paragraphs have been placed for you in Boxes. Mark your answers on ANSWER SHEET 1.[A] The strain of HIV that was discovered in Sydney intrigues scientists because it contains striking abnormalities in a gene that is believed to stimulate viral duplication. In fact, the virus is missing so much of this particular gene-known as nef, for negative factor—that it is hard to imagine how the gene could perform any useful function. And sure enough, while the Sydney virus retains the ability to infect T cells—white blood cells that are critical to the immune system’s ability to ward off infection—it makes so few copies of itself that the most powerful molecular tools can barely detect its presence.[B] If this speculation proves right, it will mark a milestone in the battle to contain the late-20th century’s most terrible epidemic. For in addition to explaining why this small group of people infected with HIV has not become sick, the discovery of a viral strain that works like a vaccine would have far reaching implications. "What these results suggest," says Dr. Barney Graham of Tennessee’s Vanderbilt University, "is that HIV is vulnerable and that it is possible to stimulate effective immunity against it."[C] But as six years stretched to 10, then to 14, the anxiety of health officials gave way to astonishment. Although two of the recipients have died from other causes, not one of the man’s contaminated blood has come down with AIDS. More telling still, the donor is also healthy. In fact his immune system remains as robust as if he had never tangled with HIV at all. What could explain such unexpected good fortune[D] At the very least, the nef gene offers an attractive target for drug developers. If its activity can be blocked, suggests Deacon, researchers might be able to bring the progression of disease under control, even in people who have developed full blown AIDS. The need for better AIDS-fighting drugs was underscored last week by the actions of a U. S. Food and Drug Administration advisory panel, which recommended speedy approval of two new AIDS drugs. Although FDA commissioner David Kessler was quick to praise the new drugs, neither medication can prevent or cure AIDS once it has taken hold. What scientists really want is a vaccine that can prevent infection altogether. And that’s what makes the Sydney virus so promising and so controversial.[E] A team of Australian scientists has finally solved the mystery. The virus that the donor contracted and then passed on, the team reported last week in the journal Science, contains flaws in its genetic script that appear to have rendered it harmless. "Not only have the recipients and the donor not progressed to disease for 15 years," marvels molecular biologist Nicholas Deacon of Australia’s Macfarlane Burnet Centre for Medical Research, "but the prediction is that they never will." Deacon speculates that this "impotent" HIV may even be a natural inoculant that protects its carriers against more virulent strains of the virus.[F] But few scientists are enthusiastic about testing the proposition by injecting HIV however weakened—into millions of people who have never been infected. After all, they note, HIV is a retrovirus, a class of infectious agents known for their alarming ability to integrate their own genes into the DNA of the cells they infect. Thus once it takes effect, a retrovirus infection is permanent.[G] About 15 years ago, a well-meaning man donated blood to the Red Cross in Sydney, Australia, not knowing he has been exposed to HIV-1, the virus that causes AIDS. Much later, public health officials learned that some of the people who got transfusions containing his blood had become infected with the same virus; presumably they were almost sure to die.Order: 43

Directions:Read the following text carefully and then translate the underlined segments into Chinese. Your translation should be written clearly on ANSWER SHEET 2.The long and progressive reign of Queen Victoria came to a climax at a time of peace and plenty when the British Empire seemed to be at the summit of its power and security. Of the discord that soon followed we shall here note only two factors which had large influence on contemporary English literature.The first disturbing factor was imperialism, the reawakening of a dominating spirit which had seemingly been put to sleep by the proclamation of an Imperial Federation. (46)Its coming was heralded by the Boer War in South Africa, through which Britain blundered to what was hoped to be an era of peace and good will. Other nations promptly made such hope a vain whistling in the wind. Japanese War Lords began a career of conquest which aimed to make Japan master of Asia and East Indies. Pacific islands that had for ages slept peacefully were turned into frowning naval stations. (47)Even the United States, aroused by an easy triumph in the Spanish War, started on an imperialistic adventure by taking control of the Philippines, thus making an implacable enemy of Japan.Only a nation that enters on a dangerous course with eyes wide open has any chance of a safe way out, and the imperialistic nations were all alike blind. (48)An inevitable result was the First War and the great horror of a Second World War, the two disasters being different acts of the same tragedy of imperialism, separated only by a breathing spell.Another factor that influenced literature for the worse was a widespread demand for social reform of every kind; not slow and orderly reform, which is progress, but immediate and uncontrolled reform, which breeds a spirit of rebellion and despair. Before the Victorian age had come to an end, English literature appeared to have lost touch with healthy English life. Many writers echoed the sorrowful cry of James Thomson in his City of Dreadful Night, or babbled of "art for art’s sake" with Oscar Wilde. (49)Groom, in his survey of the period, notes that writers had mostly a critical attitude toward morals and religion, Church and State, as relies from "the dead hand of traditional beliefs." (50)Small wonder that German and Japanese war-advocates regarded Englishmen as a decadent race when the same or a worse opinion was daily read in the novels of Samuel Butler and nightly heard in the plays of Bernard Shaw. Groom, in his survey of the period, notes that writers had mostly a critical attitude toward morals and religion, Church and State, as relies from "the dead hand of traditional beliefs."
