Preferences Vary on Circumstance of Dying
Among terminally iii people, attitudes differ on what they think constitutes a(1)or bad death, the results of a new study suggest. Dr. Elizabeth K. Vig of the University of Washington in Seattle and colleagues interviewed 26 men with(2)heart disease or cancer. The men were asked to describe good and bad deaths, and they also answered questions about their(3)for dying. "In this small study, terminally ill men described good and bad deaths(4)"Vig said. "They did not hold uniform. views about such issues(5)the presence of others at the very end of life or preferred location of death." Many of the men considered(6)in their sleep to be a good death. The reasons were varied and included not(7)that death was imminent, and that death would be painless. For close to half of the men, a prolonged death was(8)a bad death. Some of the men equated a prolonged death with prolonged pain,(9)othe. rs thought a prolonged death would be difficult for their families. Most men said that their(10)were very important to them, but this did not mean that they wanted relatives close at the(11)of death. "Valuing family did not also(12)wanting family present at the very end of life," Vig said."In fact, some expressed concerns about(13)loved ones," vig said. For instance, some men were worried about the emotional or(14)impact on their family members, according to the Washington researcher.

To get a sense of how women have progressed in science take a quick tour of the physics department at the University ofCalifornia,Berkeley.This is a storied place the 36 of some of the most important discoveries in modern science-starting withErnest Lawrence' s invention of the cvclotron(回旋加速器)in 1931.
A、 generation ago female faces were 37 and,even today,visitors walking through the first floor of LeConte Hall will See a full corridor of exhibits 38 the many distinguished physicists who made history here, 39 all of there white malesBut climb up to the third floor and you' II see a 40 display.There,among the photos of current facnlty members and students are portraits of the 41 head of the department,Marjorie Shapiro and four other women whose reseaich 42 everything from the mecheanics of the universe to the smallest particles of matter.
A、sixth woman was hired just two weeks ago.Although they' re Still only about 10 percent of the physics faculty,women are clearly a presence here.And the real 43 may be in the smaller photos to the right graduate and undergraduate students about 20 percent of them female.Every yearsBerkeley sends its fresh female physics PhDs to the country' S top universities.That makes Shapiro optimistic but also 44 "I believe things are getting bette "she says "but they' re not getting better as 45as i would like."

Part science and part natural history, ornithology(鸟类学) owes its tremendous popularity as a science and a scientific recreation to a simple circumstance that is sometimes forgotten when we weigh the eligibility(有被选资格,合适)of different kinds of animals for informal study. Birds are day animals where others, just as engaging in their way—mice, for instance—are creatures of the night. Apart from their visibility (something very much in their favor), the beauty of birds and their many appealing habits have won for them a huge fan following that has more than once tempted impatient and ill-informed laboratory biologists to dismiss ornithology as so much bird-watching—an absurdly unjust judgment that ignores the fact that ornithology has made a number of profoundly important contributions to general biology.
Professional biologists are not hard put to reel off(滔滔不绝地讲) a list of distinctive contributions that ornithology has made to general biology science. They will cite, for example, Ernst Mayr's investigations of evolution and the mechanisms of speciation (物种形成), or M. R. Irwin's work on the immunologic performance of species of Columbidae(pigeons and doves) and of hybrids(杂交种)between them. Then again, David Lack's studies on mortality in wild populations of birds are the most illuminating life tables of wild animals and animal demography (统计学) generally. Most important of all, perhaps is the contribution that ornithology has made to the study of animal behavior, beginning with Julian Huxley' s classic study of the courtship habits of the great crested great and followed by Niko Tinbergen's studies on the behavior. of herring gulls.
What is the main idea of the passage?
A.Birds are widely studied because they are popular in the home.
B.Ornithology has made important contributions to biology.
C.Professional biologists often engage in bird-watching for recreation.
D.Animal behavior. is best studied by observing birds.
