　　[A] The extra gene makes no difference normally, but when oxygen levels fall, more HO-1 is produced more quickly.

　　[B] There are already drugs that can be given to patients who suffer heart attacks or strokes to help reduce cell death.

　　[C]The gene switches on quickly in conditions of low oxygen and saves cells from death.

　　[D] Then the extra gene can save the high-risk patients from a stroke or heart attack.

　　[E] If cells could be coaxed to produce more HO-1 faster, the researchers reasoned, the cells might be saved during a stroke or heart attack. So they modified an adeno-associated virus to deliver an extra HO-1 gene to cells.

　　[F] The team now plans to test the gene therapy on larger animals such as pigs.We are convinced this strategy is going to be effective,says Dzau.

　　[G] By the time people reach a hospital and are diagnosed, it is often too late. Giving high-risk patients gene therapy in advance, by contrast, would ensure that the protective mechanism kicks in as soon as it is needed.

　　Directions：

　　Read the following passage carefully and then translate the underlined sentences into Chinese. Your translation must be written clearly on ANSWER SHEET 2. (10 points)

　　Wisdom born of experience should tell us that was is obsolete. 46) There may have been a time when war served as a negative good by preventing the spread and growth of an evil force, but the destructive power of modern weapons eliminates even the possibility that war may serve any good at all. In a day when vehicles hurtle through outer space and guided ballistic missiles carve highways of death through the stratosphere, no nation can claim victory in war. A so-called limited war will leave little more than a calamitous legacy human suffering, political and spiri??tual disillusionment. A world war will leave only smoldering ashes as mute testimony of a human race whose folly led inexorably to ultimate death. 47) If modern man continues toy unhesitat??ingly with war, he will transform his earthly habitat into a hell such as even mind of Dante (但丁) could not imagined

　　48) Therefore I suggest that the philosophy and strategy of nonviolence becomes immedi??ately a subject for study and for serious experimentation in every field of human conflict, by no means excluding the relations between nations. It is, after all, nation-states, which make war, which have produced the weapons that threaten the survival of mankind and which are both genocidal and suicidal in character.

　　We have ancient habits to deal with, vast structures of power, indescribably complicated problems to solve. 49) But until we resign our humanity altogether and yield to fear and incapability in the presence of the weapons we have ourselves created, it is as possible and as urgent to put an end to war and violence between nations as it is to put an end to poverty and racial injus??tice.

　　I do not minimize the complexity of the problems that need to be faced. 50) But I am convinced that we shall not have the will, the courage and the insight to deal with such matters unless in this field we are prepared to undergo a mental and spiritual re-evaluation, a change of focus which will enable us to see that the things that seem most real and powerful are indeed now unreal and have come under sentence of death. We need to make a supreme effort to generate the readi??ness, indeed the eagerness, to enter in to the new world, which is now possible, the city which hath foundation, whose Building and Maker is God。
