Modern scientists divide the process of dying into two stages--clinical or temporary death and biological death. Clinical death occurs when the vital organs, such as the heart or lungs, have ceased to function, but have not suffered permanent damage. The organism can still be revived. Biological death occurs when changes in the organism lead to the disintegration of vital cells and tissues. Death is then irreversible and final.
Scientists have been seeking a way to prolong the period of clinical death so that the organism can be revived before biological death occurs. The best method developed so far involves cooling of the organism, combined with narcotic sleep. By slowing down the body's metabolism, cooling delays the processes leading to biological death.
To illustrate how this works, scientists performed an experiment on a six-year-old female monkey called Keta. The scientists put Keta to sleep with a narcotic. Then they surrounded her body with ice-bags and began checking her body temperature. When it had dropped to 28 degrees the scientists began draining blood from its body. The monkey's blood pressure decreased and an hour later both the heart and breathing stopped; clinical death set in. For twenty minutes Keta remained in this state. Her temperature dropped to 22 degrees. At this point the scientists pumped blood into its body in the direction of the heart and started artificial breathing. After two minutes the monkey's heart became active once more. After fifteen minutes, spontaneous breathing began, and after four hours Keta opened her eyes and lifted her head. After six hours, when the scientists tried to give her a penicillin injection, Keta seized the syringe and ran with it around the room. Her behavior differed little from that of a healthy animal.
The best statement of the main idea of this passage is that _____

第二篇Night of the Living AntsWhen an ant dies,other ants move the dead insect out of the nest.This behavior is interesting to scien-tists,who wonder how ants know for sure一and so soon一that another ant is dead.Dong-Hwan Choe,a scientist at the University of California,found that Argentine ants have a chemical on the outside of their bodies that signals to other ants,"I'm dead一take me away."But there's a twist to Choe's discovery. These ants behave a little bit like zombies（僵尸）.Choe says that the living ants一not just the dead ones一have this death chemicals. In other words,while an ant crawls around,perhaps in a picnic or home,it's telling other ants that it's dead.What keeps ants from hauling away the living dead? Choe found that Argentine ants have two additional chemicals on their bodies,and these tell nearby ants something like,"Wait一I'm not dead yet."So Choe's research turned up two sets of chemical signals in ants:one says,"I'm dead,"the other set says,"I'm not dead yet."Other scientists have tried to figure out how ants know when another ant is dead.If an ant is knockedunconscious,other ants leave it alone until it wakes up.That means ants know that unmoving ants can still be alive.Choe suspects that when an Argentine ant dies,the chemical that says"Wait一I'm not dead yet"quickly goes away. Once that chemical is gone,only the one that says"I'm dead"is left."It's because the dead ant no longer smells like a living ant that it gets carried to the graveyard（墓地）,not because its body releases new,unique chemicals after death,"said Choe.When other ants detect the"dead"chemical without the"not dead yet" chemical,they haul away the body. This was Choe's hypothesis（假设）.To test his hypothesis,Choe and his team put different chemicals on Argentine ant pupae（蛹）.When the scientists used the"I'm dead"chemical,other ants quickly hauled the treated pupae away.When the sci-entists used the"Wait一I'm not dead yet"chemical,other ants left the treated pupae alone.Choe believes this behavior shows that the" not dead yet" chemical overrides（优先于）the" dead" chemical when picked up by adult ants.And that when an ant dies,the"not dead yet"chemical fades away.Other nearby ants then de-tect the remaining"dead"chemical and remove the body from the nest.What is meant by"death chemical"mentioned in Paragraph 3?A:A chemical that contains poison.B:A chemical that causes death.C:A chemical that announces death.D:A chemical that prevents death.

Double EffectThe Supreme Court's decisions on physician-assisted suicide carry important implications for how medicine seeks to relieve dying patients of pain and suffering.Although it ruled that there is no constitutional right to physician-assisted suicide,the Court in effect supported the medical principle of"double effect",a centuries-old moral principle holding that an action having two effects-a good one that is intended and a harmful one that is foreseen-is permissible if the actor intends only the good effect.Doctors have used that principle in recent years to justify using high doses of morphine to control terminally ill patients'pain,even though increasing dosages will eventually kill the patient.Nancy Dubler,director of Montefiore Medical Center,contends that the principle will shield doctors who"until now have very,very strongly insisted that they could not give patients sufficient mediation to control their pain if that might hasten death."George Annas,chair of the health law department at Boston Univeisity,maintains that,as long as a doctor prescribes a drug for a legitimale medical purpose,the doctor has done nothing illegal even if the patient uses the drug to hasten death."It's like surgery,"he says."We don't call those deaths homicides because the doctors didn't intend to kill their patients,although they risked their death.if you're a physician,you can risk your patient's suicide as long as you don't intend their suicide."On another level,many in the medical community acknowledge that the assisted-suicide debate has been fueled in part by the despair of patients for whom modern medicine has prolonged the physical agony of dying.Just three weeks before the Court's ruling on physician一assisted suicide,the National Academy of Science(NAS)released a two-volume report,Approaching Death:Improving Care at the End of Life.It identifies the under-treatment of pain and the aggressive use of"ineffectual and forced medical procedures that may prolong and even dishonor the period of dying" as the twin problems of end-of-life care.The profession is taking steps to require young doctors to train in hospices,to test knowledge of aggressive pain management therapies,to develop a Medicare billing code for hospital-based care,and to develop new standards for assessing and treating pain at the end of life.Annas says lawyers can play a key role in insisting that these well-meaning medical initiatives translate into better care."Large numbers of physicians seem unconcerned with the pain their patients are needlessly and predictably suffering,"to the extent that it constitutes"systematic patient abuse." He says medical licensing boards"must make it clear that painful deaths are presumptively ones that are incompetently managed and should result in license suspension."Which of the following statements is true according to the text?A:Doctors will be held guilty if they risk their patients'death.B:Modern medicine has assisted terminally ill patients in painless recovery.C:The Court ruled that high-dosage pain-relieving medication should be prescribed.D:A doctor's medication is no longer justified by his intentions.
