考题根据下列内容，回答196-200题。 If the population of the earth goes on increasing at its present rate, there will eventually notbe enough resources left to sustain life on the planet. By the middle of the 21st century, if presenttrends continue, we will have used up all the oil that drives our cars, for example. Even if scien-tists develop new ways of feeding the human race, the crowded conditions on earth will make itnecessary for us to look for open space somewhere else. But none of the other planets in our solarsystem are capable of supporting life at present. One possible solution to the problem, however, has recently been suggested by an American scientist, Professor Carl Sagan. Sagan believes that before the earth's resources are completely exhausted it will be possible tochange the atmosphere of Venus and so create a new world almost as large as earth itself. The dif-ficulty is that Venus is much hotter than the earth and there is only a tiny amount of water there. Sagan proposes that algae organisms, which can live in extremely hot or cold atmospheres andat the same time produce oxygen, should be bred in conditions similar to those on Venus. As soonas this has been done, the algae will be placed in small rockets. Spaceships will then fly to Venusand fire the rockets into the atmosphere. In a fairly short time, the algae will break down the car-bon dioxide into oxygen and carbon. When the algae have done their work, the atmosphere will become cooler, but before mancan set foot on Venus it will be necessary for the oxygen to produce rain. The surface of the planetwill still be too hot for men to land on it but the rain will eventually fall and in a few years some-thing like earth will be reproduced on Venus. In the long run, the most difficult problem caused by population growth on earth willprobably be the lack of __________.A.food B.oil C.space D.resources

考题共用题干 Prolonging Human Life1.Prolonging human life has increased the size of the human population.Many people alive today would have died of childhood diseases if they had been born 100 years ago.Because more people live longer,there are more people around at any given time.In fact,it is a decrease in death rates,not an increase in birthrates,that has led to the population explosion.2.Prolonging human life has also increased the dependency load.In all societies,people who are disabled or too young or too old to work are dependent on the rest of society to provide for them. In hunting and gathering cultures,old people who could not keep up might be left behind to die.In times of famine,infants might be allowed to die because they could not survive if their parents starved,whereas if the parents survived they could have another child.3.In most contemporary societies,people feel a moral obligation to keep people alive whether they can work or not. We have a great many people today who live past the age at which they want to work or are able to work.We also have rules which require people to retire at a certain age.Unless these people were able to save money for their retirement,somebody else must support them.In the United States many retired people live on social security checks which are so little that they must live in near poverty. Older people have more illness than young or middle-aged people.Unless they have wealth or private or government insurance,they must often"go on welfare"if they have a serious illness.4.When older people become senile or too weak and ill to care for themselves,they create grave problems for their families.In the past and in some traditional cultures,they would be cared for at home until they died.Today,with most members of a household working or in school,there is often no one at home who can care for a sick or weak person.To meet this need,a great many nursing homes and convalescent hospitals have been built. These are often profit-making organizations, although some are sponsored by religious and other nonprofit groups.While a few of these institutions are good,most of them are simply"dumping grounds"for the dying in which"care"is given by poorly paid,overworked,and under-skilled personnel.Paragraph 4________A:The old people are heavy load for the society.B:Prolonging human life may lead to population explosion.C:How to prolong human life.D:Dependency load caused by prolonging human life.E:Increased birthrate helps prolong human life.F: How the old people are cared for when they are getting weak in contemporary society.

考题 Passage Four Ideasabout polite behaviour differ from one culture to another.Some societies,such asAmerica and Australia,for example,are mobile and veryopen.People here change jobs and move house quiteoften.As a m result,they have a lot of relationships that often last only mashort time,and they need to get to know people quickly.So it′s normal to havefriendly conversations with people that they have just met,and you can talk aboutthings that other cultures would regard as personal. On the other hand,there are more crowded and less mobile societies where long-termrelationships are more important.A Malaysian or Mexican business person,for example,willwant to get to know you very well before he or she feels happy to startbusiness.But when you do get to know each other,the relationship becomes muchdeeper than it would in a mobile society. To Americans,both Europeans and Asians seem cool and formal atfirst.On the other hand,as a passenger from a less mobile society puts it,it′s no fun spending several hours next to a stranger who wants to tell you allabout his or her life and asks you all sorts of questions that you don′t want to answer. Cross-cultural differences aren′t just a problem for travelers,but also for people in daily life.Some societies have"universalist′′cultures.These societies strongly respect rules,and they treat every personand situation in basically the same way."Particularist"(强调特性的)societies also have rules,but they are less important than thesociety′s unwritten ideas about what is right or wrong for a particularsituation or a particular person.So the normal rules are changed to fit theneeds of the situation or the importance of the person.

考题共用题干 So Many"Earths"The Milky Way（银河）contains billions of Earth-sized planets that could support life.That's the finding of a new study.It draws on data that came from NASA's top planet-hunting telescope.A mechanical failure recently put that Kepler space telescope out of service.Kepler had played a big role in creating a census of planets orbiting some 170,000 stars.Its data have been helping astronomers predict how common planets are in our galaxy.The telescope focused on hunting planets that might have conditions similar to those on Earth.The authors of a study,published in The Proceedings of the National Academy of Sciences,conclude that between 14 and 30 out of every 100 stars,with a mass and temperature similar to the Sun,may host a planet that could support life as we know it.Such a planet would have a diameter at least as large as Earth's,but no more than twice that big.The planet also would have to orbit in a star's habitable zone.That's where the surface temperature would allow any water to exist as a liquid.The new estimate of how many planets might fit these conditions comes from studying more than 42,000 stars and identifying suitable worlds orbiting them.The scientists used those numbers to extrapolate（推算） to the rest of the stars that the telescope could not see.The estimate is rough,the authors admit.If applied to the solar system,it would define as habitable a zone starting as close to the Sun as Venus and running to as far away as Mars.Neither planet is Earthlike (although either might have been in the distant past).Using tighter limits,the researchers estimate that between 4 and 8 out of every 100 sunlike stars could host an Earth-sized world.These are ones that would take 200 to 400 days to complete a yearly orbit.Four out of every 100 sunlike stars doesn't sound like a big number.It would mean,however,that the Milky Way could host more than a billion Earth-sized planets with a chance for life.The planet that could support life might be a little bit smaller than Earth.A:Right B:Wrong C:Not mentioned
