考题 Prehistoric men and women enjoyed a more varied diet(饮食)than people do now, since they ate species(种类)of plant and several hundred thousand types of living things. But only a tiny percentage of these were ever domesticated(驯化). Modern shops have hastened a trend towards specialization which began in the earliest days of agriculture. The food of rich countries has become cheaper relative to wages. It is speedily distributed in supermarkets, but the choice annually becomes less and less great. Even individual foods themselves become more standardized. We live in the world of the carrot specially blunted in order to avoid making a hole in the bag, and the tomato grown to meet a demand for a standard weight of eighteen tomatoes to a kilo. Siri von Reis Altschul asks: "Only the tree major cereals(谷物)and perhaps ten other widely cultivated species stand between famine and survival for the world's human population and a handful of drug plants has served Western civilization for several thousand years. A rather obvious question arises: are we missing something?" After all, there are 800,000 species of plant on earth.1.

考题 Passage 2 The Ancient Greek philosopher Pythagoras is best known today for his mathematical theorem,which haunts the dreams of many geometry students, but for centuries he was also celebrated as thefather of vegetarianism. A meatless diet was referred to as a "Pythagorean diet" for years, up untilthe modem vegetarian movement began in the mid-1800s. While Pythagoras was an early proponent of a meatless diet, humans have been vegetarianssince well before recorded history.Most anthropologists agree that early humans would have eaten apredominantly plant-based diet;after all,plants can ’t run away.Additionally,our digestive systemsresemble those of herbivores closer than camivorous animals.Prehistoric man ate meat,of course,but plants formed the basis of his diet. Pythagoras and his many followers practiced vegetarianism for several reasons,mainly due toreligious and ethical objections.Pythagoras believed all living beings had souls.Animals were noexception,SO meat and fish were banished from his table.Strangely enough,he also banished avegetable that has a place of honor on most vegetarian menus today,the humble bean.His followerswere forbidden to eat or even touch beans,because he thought beans and humans were created fromthe same material.Fava beans were especially bad,as they have hollow steams that could allow thesouls of the dead to travel up from the soil into the growing beans. While the edict against beans was lifted not long after Pythagoras’death,his followerscontinued to eat a meatless diet.His principles influenced generations of academics and religiousthinkers,and it was a group of these like-minded individuals who founded the Vegetarian Society inEnglish in the mid-1800s.The virtues of temperance,abstinence and self.control were all tied tovegetarian Ideals,while lust,drunkenness and general hooliganism all resulted from a diet too rich inmeat products.Notable early vegetarians included Leo Tolstoy,George Bernard Shaw,MahatmaGandhi and American Bronson Alcott,a Transcendentalist teacher,reformer and the father of“LialeWomen”author Louisa May Alcott. It wasn’t until the 1960s that vegetarianism moved into mainstream American life and themovement’sgrowth picked up speed in the l 970s when a young graduate student named FrancisMoore Lappe wrote a book called Diet for a Small Planet.In it,she advocated a meatless diet not forethical or moral reasons,but because plant-based foods have much less impact on the environmentthan meat does.Today,many vegetarians refuse meat because of animal rights issues,or concernsover animal treatment,a principle first espoused in Peter Singer’s 1975 work A nimal Liberation. What issue were vegetarians in the mid-1800s in England primary reason with whenrefusing to eat meat A.Environmental protection. B.Animal rights. C.Religious belief. D.Moral purity.

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 Text 4 Consuming high-quality plant foods such as whole grains,fruits,vegetables,nuts and legumes may substantially lower risk of developing type 2 diabetes,researchers including one of Indian-origin have claimed."This study highlights that even moderate dietary changes in the direction of a healthful plant-based diet can play a significant role in the prevention of type 2 diabetes,"said Ambika Satija from Harvard T.H.Chan School of Public Health in the US."These findings provide further evidence to support current dietary recommendations for chronic disease prevention,"she said.While previous studies have found links between vegetarian diets and improved health outcomes,including reduced risk of type 2 diabetes,this new study is the first to make distinctions between healthy plant-based diets and less healthy ones that include things like sweetened foods and beverages,which may be detrimental for health.The study also considered the effect of including some animal foods in the diet.Researchers followed more than 200,000 male and female health professionals in the US for more than 20 years who had regularly filled out questionnaires on their diet,lifestyle,medical history,and ncw disease diagnoses as part of three large long-term studies.They evaluated participants'diets using a plant-based diet index in which they assigned plant-derived foods higher scores and animal-derived foods lower scores.The study found that high adherence to a plant-based diet that was low in animal foods was associated with a 20 percent reduced risk of type 2 diabetes compared with low adherence to such a diet,researchers said.Eating a healthy version of a plant-based diet was linked with a 34 per cent lower diabetes risk,while a less healthy version-including foods such as refrned grains,potatoes,and sugar-sweetened beverages-was linked with a 16 per cent increased risk,they said.Even modestly lowering animal food consumption-for example,from 5-6 servings per day to about 4 servings per day-was linked with lower diabetes incidence,the study found."A shift to a dietary pattern higher in healthful plant-based foods,such as vegetables,fruits,whole grains,legumes,nuts,and seeds,and lower in animal-based foods,especially red and processed meats,can confer substantial health benefits in reducing risk of type 2 diabetes,"said Frank Hu from Harvard Chan School.Researchers suggest that healthful plant-based diets could be lowering type 2 diabetes risk because such diets are high in fiber,antioxidants,unsaturated fatty acids,and micronutrients such as magnesium,and are low in saturated fat.Healthy plant foods may also be contributing to a healthy gut microbiome,they said. From the new study,we can infer that_____A.sweet fruit juice and beverages are beneficial to our health B.animal foods should not be included in our diet for the sake of health C.fried potatoes are healthy food comparing with animal foods D.eating less meat is helpful to reduce the diabetes incidence

考题 共用题干 第一篇A Society Without a Formal AuthorityIn the seventeenth century,European soldiers who came across some Indian groups in the westem Great Lakes found that several native tribes(部落)were living in the area without a formal leadership system.They appeared to be"quite friendly with each other without a formal authority"!Not only did the Indians appear to lack a formal system of authority,but they also deeply hated any efforts to control their actions.All members of the tribes knew what was required of them by lifelong(一生的)familiarity with the tasks of the area.

考题 问答题Practice 2  We must work passionately and indefatigably to bridge the gulf between our scientific progress and our moral progress. One of the great problems of mankind is that we suffer from a poverty of the spirit which stands in glaring contrast to our scientific and technological abundance. The richer we have become materially, the poorer we have become morally and spiritually.  Every man lives in two realms, the internal and the external. The internal is that realm of spiritual ends expressed in art, literature, morals and religion. The external is that complex of devices, techniques, mechanisms and instrumentalities by means of which we live. Our problem today is that we have allowed the internal to become lost in the external. We have allowed the means by which we live to outdistance the ends for which we live. So much of modern life can be summarized in that suggestive phrase of Thoreau: “Improved means to an unimproved end. “ This is the serious predicament, the deep and haunting problem, confronting modern man. Enlarged material powers spell enlarged peril if there is not proportionate growth of the soul. When the external of man’s nature subjugates the internal, dark storm clouds begin to form.
