To paraphrase18th-century statesman Edmund Burke,“all that is neededfor the triumph of a misguided cause is that good people do nothing。”One suchcause now seeks to end biomedical research because of the theory that animalshave rights ruling out their use in research. Scientists need to respondforcefully to animal rights advocates, whose arguments are confusing the publicand thereby threatening advances in health knowledge and care. Leaders of theanimal rights movement target biomedical research because it depends on publicfunding, and few people understand the process of health care research. Hearingallegations of cruelty to animals in research settings, many are perplexed thatanyone would deliberately harm an animal。
For example, a grandmotherly woman staffing an animal rights boothat a recent street fair was distributing a brochure that encouraged readers notto use anything that comes from or is animals—no meat , no fur, nomedicines, Asked if she opposed immunizations, she wanted to know if vaccinescome from animal research. When assured that they do, she replied, “Then I wouldhave to say yes。” Asked what will happen when epidemics return, she said, “ Don’t worry,scientists will find some way of using computers。” Such well-meaningpeople just don't understand。
Scientists must communicate their message to the public in acompassionate, understandable way—in human terms, not in the language of molecular biology. We need tomake clear the connection between animal research and a grandmother's hipreplacement, a father's bypass operation, a baby's vaccinations, and even apet's shots. To those who are unaware that animal research was needed toproduce these treatments, as well as new treatments and vaccines, animalresearch seems wasteful at best and cruel at worst。
Much can be done. Scientists could“adopt”middleschool classes and present their own research. They should be quick to respondto letters to the editor, lest animal rights misinformation go unchallenged andacquire a deceptive appearance of truth. Research institutions could be openedto tours, to show that laboratory animals receive humane care. Finally, becausethe ultimate stakeholders are patients, the health research community shouldactively recruit to its cause not only well-known personalities such as StephenCooper, who has made courageous statements about the value of animal research,but all who receive medical treatment. If good people do nothing there is areal possibility that an uninformed citizenry will extinguish the preciousembers of medical progress。

I am a neuroscientist.I make a living by studying how the brain works.Although neuroscience has taken huge strides forward in the past decade，it is a long way from being able to address the problems dealt with by psychotherapy.3) Neuroscience cannot yet explain how we feel，and it is a long way from being able to prescribe what a miserable person must do to feel better.So，as a neuroscientist，I feel I should have a conclusion about the alternative approach.
The first question I must answer is：“What do psychotherapies have to offer?”First，let us deal with the scientific angle.The best way to start is by assessing a claim that has cropped up several times over the year.It was first made of psychoanalysis，but it has been extended to other psychotherapies.It is the claim that psychoanalysis is the successor to religion，that it gives a scientific，rather than a superstitious，answer to the question of how best to lead a happy，fulfilled life.
I would say this claim is at best half right.Psychoanalysis may indeed answer the question of how best to lead a happy life，but it has a lot more in common with religion than it has with science.In fact，psychoanalysis is not the successor to religion，it is just another religion.
This assessment is based on the way religions and sciences deal with fundamental truths.In religions，truths are laid down by God and revealed to the prophets who，in their turn，pass them on to the faithful.They are sacred mysteries that cannot be questioned.In science，on the other hand，truths are nothing if not questionable.The laws of science are deduced from the results of experiments and can be used to predict new experimental results.If new results go against the prediction，they show the law to be false.A new experimental result，or a new theory for deriving predictions from the results，can change the accepted truths.If a scientific statement cannot，in principle，be proved wrong then it tells us nothing.
Psychoanalysis suffers from just this problem.4)It is a maxim that our psychological problems are rooted in past conflicts，and that the repressed memories of these conflicts emerge from the unconscious in coded forms that can be interpreted by the analyst.But the codes are so obscure and so flexible that they defy rational explanation.There is no way the maxims could be disproved.They may not be sacred，but they are definitely mysteries.
Many other therapies are based on untestable theories.Of course，that doesn‘t necessarily prevent them from working.There is no doubt thousands of people feel that psychoanalysis has helped them to lead fuller and happier lives.But the number of satisfied customers is no guide to scientific validity;if it were，religion would come out way ahead.
36. The author considers his role as a neuroscientist____.
[A]irrelevant to that of a psychoanalyst
[B]different from that of a psychoanalyst
[C]of the same importance as that of a psychotherapeutist
[D]purely imaginary and impractical
37. According to the author，psychoanalysis is another religion in that____.
[A]it does nothing towards revealing fundamental truth
[B]its conclusions are seldom capable of being tested
[C]it has too many prophets and blind believers
[D]it takes over many doctrines from religious beliefs
38. By saying that“Psychoanalysis suffers from just this problem”(Para.5)the author means that____.
[A]psychoanalysis deals with problems or conflicts inside the unconscious
[B]the assertions in psychoanalysis cannot be disproved
[C]psychoanalysis attaches no importance to doing experiments
[D]psychoanalysts can not explain psychological problems to patients
39. Which of the following is a science according to the author?
[A]Neuroscience.
[B]Psychoanalysis.
[C]Psychotherapy.
[D]None of the above.
40. The main purpose of the passage is____.
[A]to refute the practical value of psychoanalysis
[B]to propose neuroscience as an alternative to psychoanalysis
[C]to compare the theories of psychoanalysis with religious doctrines
[D]to explain why psychoanalysis is not a science

Long before Man lived on the Earth, there were fishes, reptiles,birds, insects, and some mammals. Although some oftheseanimals were ancestors of kinds living today, others are now extinct, that is,they have no descendants alive now. 41. Very occasionally the rocks showimpression of skin, so that, apart from color, we can build up a reasonablyaccurate picture of an animal that died millions of years ago. The kind of rockin which the remains are found tells us much about the nature of the originalland, often of the plants that grew on it, and even of its climate.
42. . Nearly all of the fossils that we know were preserved in rocksformed by water action, and most of these are of animals that lived in or nearwater. Thus it follows that there must be many kinds of mammals, birds, andinsects, of which we know nothing.
43. . There were also crab-like creatures, whose bodies were coveredwith a horny substance. The body segments each had two pairs of legs, one pairfor walking on the sandy bottom, the other for swimming. The head was a kind ofshield with a pair of compound eyes, often with thousands of lenses. They wereusually an inch or two long but some were 2 feet.
44. . Of these, the ammonites are very interesting and important.They have a shell composed of many chambers, each representing a temporary homeof the animal. As the young grew larger it grew a new chamber and sealed offthe previous one. Thousands of these can be seen in the rocks on the DorsetCoast.
45. .About 75 million years ago the Age of Reptiles was over andmost of the groups died out. The mammals quickly developed, and we can tracethe evolution of many familiar animals such as the elephant and horse. Many ofthe later mammals, though now extinct, were known to primitive man and werefeatured by him in cave paintings and on bone carvings.
［A］ The shell gush have a long history in the rock and many differentkinds are known.
［B］ Nevertheless, we know a great deal about many of them because theirbones and shells have been preserved in the rocks as fossils. From them we cantell their size and shape, how they walked, the kind of food they ate.
［C］ The first animals with true backbones were the fishes, first knownin the rocks of 375 million years ago. About 300 million years ago theamphibians, the animals able to live both on land and in water, appeared. Theywere giant, sometimes 8 feet long, and many of them lived in the swampy poolsin which our coal seam, or layer, or formed. The amphibians gave rise to thereptiles and for nearly 150 million years these were the principal forms oflife on land, in the sea, and in the air.
［D］ The best index fossils tend to be marine creatures. These animalsevolved rapidly and spread over large areas of the world.
［E］ The earliest animals whose remains have been found were all verysimple kinds and lived in the sea. Later forms are more complex, and amongthese are the sealilies, relations of the starfishes, which had long armsand were attached by a long stalk to the sea bed, or to rocks.
［F］ When an animal dies the body, its bones, or shell, may often becarried away by streams into lakes or the sea and there get covered up by mud.If the animal lived in the sea its body would probably sink and be covered withmud. More and more mud would fall upon it until the bones or shell becomeembedded and preserved.
［G］ Many factors can influence how fossils are preserved in rocks.Remains of an organism may be replaced by minerals, dissolved by an acidicsolution to leave only their impression, or simply reduced to a more stableform.
