Doctor Goldberger travelled to the state of Mississippi where many people had pellagra.He studied the patients and their families.Most of the people were poor.The doctor came to believe that the disease was not passed from one person to another,but instead had something to do with food. He received agreement from state officials to test this idea at a prison(监狱).Prisoners were offered pardons if they took part.One group of prisoners received their usual food,mostly corn.A second group ate meat,fresh vegetables and milk.Members of the first group developed pellagra.The second group did not. But some experts refused to accept that poor food caused pellagra.They thought there were other causes. So Doctor Goldberger put blood(血液)from a person with pellagra into his own body.He even took pills that had blood from pellagra patients.An assistant also took part in the experiments.So did Doctor Goldberger’s wife.None of them got sick.Later,the doctor discovered that a bit of dried brewer’s yeast(酿酒的酵母)each day could prevent pellagra. Joseph Goldberger died of cancer in 1929.He was 55 years old.Several years later,researchers discovered the true cause of pellagra:having little of the vitamin B. 21.How old was Doctor Goldberger when he began to study pellagra? A.22. B.30. C.38. D.55. 答案C 解析数字计算题。从最后一段中的“Joseph Goldberger died of cancer in 1929.He was 55 years old.”可计算出,约瑟夫·古德伯格出生于1874年,所以1912年研究烟酸缺乏病时,他38岁。 22.The underlined part “this idea”(in Paragraph 3)refers to . A.the guess that pellagra had something to do with food B.a kind of yeast that prevented pellagra C.pellagra that was easily passed from one person to another D.a poor food that caused pellagra 答案A 解析词义理解题。从第二段最后一句“The doctor came to believe that the disease was not passed from one person to another,but instead had something to do with food.”以及第三段可知,这种想法指的是对这种疾病与食物有关的猜想。 23.Which is the right order about what Doctor Goldberger did? a.He did a test on prisoners at a prison. b.He did the experiments on himself. c.He came to Mississippi to study the patients and their families. d.He found poor food was easy to cause pellagra. e.He discovered a little dried brewer’s yeast every day could prevent pellagra. A.a,d,c,e,b B.c,a,d,b,e C.b,e,c,a,d D.c,b,e,a,d 答案B 解析细节理解题。根据第二、三、五段可知B项正确。 24.This passage mainly tells us . A.Doctor Goldberger’s life B.something about pellagra C.Doctor Goldberger’s work experience D.Doctor Goldberger’s study on pellagra 答案D 解析主旨大意题。通读全文可知本文介绍了约瑟夫·古德伯格医生对烟酸缺乏病的研究。 B 导学号91364031 (思维品质 语言能力) Science can’t explain the power of pets,but many studies have shown that the company of pets can help lower blood pressure(血压) and raise chances of recovering from a heart attack,reduce loneliness and spread all-round good cheer. Any owner will tell you how much joy a pet brings.For some,an animal provides more comfort than a husband/wife.A study by Karen Allen of the State University of New York measured stress(紧张) levels and blood pressure in people—half of them are pet owners—while they performed 5 minutes of mental arithmetic(算术) or held a hand in ice water.Subjects completed the tasks alone,with a husband/wife,a close friend or with a pet.People with pets did it best.Those tested with their animal friends had smaller change in blood pressure and returned most quickly to baseline heart rates.With pets in the room,people also made fewer math mistakes than when doing in front of other companions.It seems people feel more relaxed(放松) around pets,says Allen,who thinks it may be because pets don’t judge. A study reported that having a pet dog not only raises your spirits but may also have an effect on your eating habits.Researchers at Northwestern Memorial Hospital spent a year studying 36 fat people and their equally fat dogs on diet and exercise programs;a separate group of 56 people without pets were put on a diet program.On average,people lost about 11 pounds of 5% of their body weight.Their dogs did even better,losing an average of 12 pounds,more than 15% of their body weight.Dog owners didn’t lose any more weight than those without dogs but,say researchers,got more exercise overall—mostly with their dogs—and found it worth doing. 25.What does the text mainly discuss? A.What pets bring to their owners. B.How pets help people calm down. C.People’s opinions of keeping pets. D.Pets’ value in medical research. 答案A 解析主旨大意题。研究表明,有宠物的陪伴,主人可以降低血压,大大提高心脏病康复的机会,减少孤独感,有好的情绪等等。 26.We learn from the text that a person with heart disease has a better chance of getting well if . A.he has a pet companion B.he has less stress of work C.he often does mental arithmetic D.he is taken care of by his family 答案A 解析细节理解题。由文章第一段中的“...the company of pets can help lower blood pressure(血压)and raise chances of recovering from a heart attack...”可知答案为A项。 27.According to Allen,why did the people do better with pets around when facing stressful tasks? A.They have lower blood pressure. B.They become more patient. C.They are less nervous. D.They are in higher spirits. 答案C 解析细节理解题。由第二段中的“It seems people feel more relaxed(放松) around pets,says Allen,who thinks it may be because pets don’t judge.”可知C项正确。 28.The research mentioned in the last paragraph reports that . A.people with dogs did more exercise B.dogs lost the same weight as people did C.dogs liked exercise much more than people did D.people without dogs found the program unhelpful 答案A 解析推理判断题。由文章最后一段中的“Dog owners didn’t lose any more weight than those without dogs but,say researchers,got more exercise overall...”可知A项正确。 C (思维品质 语言能力) The famous research scientist Stephen Glenn,who had made very important medical achievements,was being interviewed by a newspaper reporter.The reporter asked Stephen Glenn why he was able to be so much more creative than others. He said that it all came from an experience with his mother that happened when he was two years old.He tried to carry a bottle of milk from the refrigerator.But carelessly,the bottle fell and milk sprinkled all over the kitchen floor. When his mother came into the kitchen,instead of complaining about it,she said,“Robert,what a great and wonderful mess you have made!Well,the terrible thing has already been done.Would you like to get down and play in the milk for a few minutes before we clean it up?” Indeed,he did.After a few minutes,his mother said,“You know,Robert,whenever you make a mess like this,you have to clean it up.We could use a sponge(海绵) or a towel.Which do you prefer?”He chose the sponge and together they cleaned up the milk. His mother then said,“You know,what we have here is a failed experiment in how to carry a big milk bottle with two small hands.Let’s go out in the backyard and fill the bottle with water and see if you can discover a way to carry it without dropping it.”The little boy learned that if he held the bottle at the top near the lip(容器的嘴) with both hands,he could carry it without dropping it.What a wonderful lesson!At that moment he knew that he didn’t need to be afraid to make mistakes and mistakes were just opportunities for learning something new. 29.When Stephen Glenn’s mother saw the mess in the kitchen,she was . A.angry B.patient C.happy D.sad 答案B 解析推理判断题。根据第三段中的“...instead of complaining about it,she said...”可知B项正确。 30.How did Stephen Glenn learn to carry a bottle of milk without dropping it? A.He tried carrying it over and over again. B.He experimented by carrying a bottle of water. C.He did as what his mother told him to. D.His teacher told him. 答案B 解析细节理解题。根据最后一段“Let’s go out in the backyard and fill the bottle with water and see if ...”可知B项正确。 31.Which of the following is NOT true? A.When Stephen Glenn sprinkled the milk,his mother didn’t complain about it. B.After the experience,Stephen Glenn understood that he didn’t need to be afraid to make mistakes. C.He experimented by carrying a bottle of water instead of milk. D.His mother thought that his hand was too small to hold the bottle. 答案D 解析细节理解题。根据最后一段母亲说的话“...what we have here is a failed experiment in how to carry a big milk bottle with two small hands.”可知D项错误。 D 导学号91364032 (思维品质 语言能力) Recently I paid a visit to Harvard University,where there are top class scientists and professors and the best academic(学术的) system in the world. I was pretty shocked when I first stepped onto the campus(校园).Well,it’s not even really a campus.It’s more like a district in a small town. Harvard’s main buildings are from the 18th century.They look very old and simple.You might even say they’re a little old.They don’t fit the modern idea of university at all.The buildings are surrounded by grass and trees,so I felt as if I had walked into a medieval castle(中世纪的城堡).But when I looked across the street,busy shops and in-fashion students made me feel like I was in the 21st century again.It creates a strong contrast(对比)and brings a special atmosphere to the school. Our tour guide Gary took us around and told us,“You see this grass field in the center of the school?Here is where they host their graduation ceremony(毕业典礼).They just set up tents and benches and have a very simple ceremony.” Unbelievable!Who would think the most talented students just graduate on the lawn? I saw some students put a blanket on the grass and lie down to read a book.When I listened to the soft sound of pages turning,along with singing of the birds,I felt very calm.There was no competitive feeling at all. Harvard has the world’s first computer in its science center and there are hundreds of high-end computers too.Its religion and the literature departments are also among the best.It is the perfect mix of tradition and new technology.It makes Harvard a very attractive place to study in.I hope one day I’ll attend my dream school—Harvard. 32.The article is mainly about . A.the author’s campus life in Harvard B.the author’s impression of Harvard C.Harvard’s old buildings D.the academic system at Harvard 答案B 解析主旨大意题。本文主要描述了作者参观哈佛大学时的见闻和感受。 33.The author was most impressed by ,according to the article. A.Harvard’s mix of tradition and new technology B.the classes held on beautiful lawns at Harvard C.Harvard students not taking their graduation ceremony seriously D.the feeling of not living in modern society on the campus 答案A 解析细节理解题。根据最后一段中的“It is the perfect mix of tradition and new technology.” 可知A项正确。 34.According to the article,in which fields is Harvard top in the world? A.Literature,arts,and law. B.Religion,law and arts. C.Literature,arts and computer science. D.Religion,computer science and literature. 答案D 解析细节理解题。最后一段提到了哈佛的三个顶尖学科——宗教学、计算机科学和文学。 35.Which word can be used to describe the Harvard campus? A.Modern. B.Competitive. C.Peaceful. D.Old. 答案C 解析推理判断题。根据第三段对哈佛大学建筑的描述,第四段毕业典礼简朴的场面,以及第五段对校园草坪景象的描述可看出哈佛大学的校园是宁静的。 第二节(共5小题;每小题2分,满分10分) 根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。 (语言能力) Choosing a college major is one of the most important choices you can make about your education and future career.It may even be more important than where you attend college.36. 37. Begin by making a list of your personal interests and careers which correspond with them.If you enjoy marine life,for instance,you should consider a marine biology major.If you love star-gazing,consider becoming an astronomer. 38. If you’re not strong in math you had better not choose engineering.If you are good at English,you might choose to become a writer or a reporter.Compare the list of your interests with the list of your talents and see which fields overlap(交叉). Once you’ve established a list of potential career fields,research them further to determine which college majors are most proper.39. If you struggle with these steps,consider looking for outside help. Choosing a college major you will enjoy is important.40. You might also avoid the unpleasantness that comes with changing your major.Perhaps most importantly,choosing the correct major may improve your overall happiness and quality of life. A.Your teacher is there to help with just this sort of dilemma. B.Then you can get an idea for what courses you’ll need to take. C.Next,consider the academic subjects in which you excel. D.Your future career choices may rely heavily on what you study in college. E.You might find college life to be less stressful if you enjoy your classes.
