an umbrella；it rarely rains here.Melissa answered the door.She was quiet and downhearted，with dark bags under her eyes，and probably anemic(贫血的).She devoted all of her time to taking care of Bradley，at her expense.Since his ALS(肌萎缩侧索硬化症) diagnosis，Bradley had become steadily weaker and less capable.He had been robbed of the ability to stand，walk or to use his legs and arms.Melissa hugged me in the doorway，the desperate grasp of someone who had lost hope.She had never seen me.It didn’t matter.The hospice(临终关怀所) makes strangers family.Melissa took my wet sweater in the doorway，saying，“I don’t see your wings，but I know they are there.You are surely an angle.” She invited me in，offered me a cookie and showed me a seat.That day stands out，maybe because Bradley and Melissa are so much like me and my husband.Maybe because I saw my own depressed face in hers.Maybe because of the deep fear that I felt—the fear of losing someone you love so deeply that the world couldn’t possibly continue to move around the sun without him or her.When you tell people you’re a hospice nurse，the expected comment is always，“Oh I could never do that.I would cry all the time.” In truth，those who work in hospice do cry，not every day，but certainly enough.Still，despite the tears shed，there is a real privilege of being at the bedside of the dying.Now I’ve traded my stethoscope(听诊器) for a laptop，but my hospice experiences never fade away，and what I learned from the dying is important and worth sharing.Don’t sweat over small stuff.At the end of your life，everything that is not vitally important—oh，let’s say，whether or not your pants are too tight—suddenly seems really unimportant.Ask yourself if what worries you will still worry you in 10 or 20 or 50 years.Answer honestly.Pay attention to pains，aches or symptoms of disease，especially those involving your breasts，internal organs or skin.These things sneak up on you.Many people wish they had faced their fear，seen the doctor earlier and gotten treatment earlier.Money is an illusion.You think you need so much.In the end，you don’t really need any of it.Prioritize(优先考虑) people and experiences over possession.The key to a long life？There isn’t one.But a 105-year-old woman told me that she lived to be that old because she “didn’t take no shit from nobody”.The same woman told me that the one piece of advice that she would give to any woman is this：“A woman can do any damn thing that a man can do.You don’t need no man for nothing.”Your body is just a vessel for your soul.Quit looking in the mirror.Quit thinking about your wrinkles，your dress size，etc.Quit worrying about your hair，makeup，or that mole(痣) on your chin (unless it might be cancerous).Quit thinking about any of that shit.It all fades anyway，one way or another.Repair what’s broken.Above all else，at the end of people’s life，the one regret that every person shares is broken relationships.Whether it’s with your parents，your children or your brothers and sisters，if it can be repaired，repair it.At the end，love is everything.In the hospice there are a lot of tears，and a lot to learn.1.What was the author’s first impression of Melissa?A.She seemed to be expecting her arrival.B.She looked very tired and in poor health.C.She was unhappy and didn’t welcome her.D.She must have just cried over something.2.What is the most possible relationship between Bradley and Melissa?A.Husband and wife.B.V olunteer and patient.C.Nurse and patient.D.Brother and sister.3.What is the privilege of being at the bedside of the dying?A.You can learn how to treat these patients well.B.You can enjoy the same treatment as the patients.C.You can be blessed with peace and love in the future.D.You can have access to something about the meaning of life.4.The underlined sentence “These things sneak up on you.” in Paragraph 7 suggests that .A.pains will always go along with youB.diseases will certainly threaten your healthC.bad things would happen to you suddenlyD.disease symptoms tend to escape your attention5.According to the passage，which of the following is TRUE?A.Nothing is important in the world at all.B.Get ready to accept whatever happens to you.C.Family affection and friendship matter the most.D.Beautiful appearance makes you achieve great success.6.The key to the long life of the 105-year-old woman is .A.never to do things on her ownB.never to overlook other people’s opinionsC.never to care about what others say about herD.never to challenge herself to do what others expectⅡ.佳作背诵(家庭、朋友与周围的人)请阅读下面短文，并按照要求用英语写一篇150词左右的文章。

Since Scottish scientists reported that they had 27 to clone a sheep named Dolly in 1997, research into cloning has grown rapidly. In May 1998, scientists in Massachusetts managed to create two identical calves(牛犊) 28 cloning technology. A mouse has 29 been cloned successfully, but the debate over cloning humans really started when Chicago 30 Richard Seed made a surprising announcement. "We will have managed to clone a human being within the next two years," he told the world.Seed's announcement 31 a lot of media attention. In Europe, nineteen nations have already 32 an agreement banning human cloning and in the US the President 33 : "We will be introducing 34 law to ban human cloning and many states in the US will have 35 anti-cloning laws by the end of the year."Many researchers are not so negative 36 cloning. They are worried that laws 37 human cloning will threaten important research. In March, the New England Journal of Medicine called any plan to ban research on cloning humans 38 mistaken. Many researchers also believe that 39 attempts to ban it, human cloningwill have become routine by 2010 because it is 40 to stop the progress of science.Is there a reason to fear that cloning will 41 a nightmare world? The public has been bombarded(轰炸) with newspaper articles, television shows and films, 42 cartoons. Such information is often misleading, and makes people 43 what on earth the scientists will be doing next.44 the next five to ten years scientists will probably have found a way of cloning humans.

A. much B. pretty C. too D. more五、阅读理解（共16小题；共32分）AAuthors Kyle Kurpinski and Terry D. Johnson pretty much have me convinced that human cloning is quite possible and is a future certainty. Kurpinski and Johnson are both bioengineering experts; unlike similar scientists you have seen in the movies, they both have a sense of humor. What surprises me is that Kurpinski and Johnson are able to take something as complicated as DNA and make it understandable.The book How to Defeat Your Own Clone teaches us what is now known as DNA-encoded, how that happens, and why people with similar DNA don't look or act the same. The book not only helps us get a basic understanding of what DNA and its purpose are, but also explains cloning and stem cell (干细胞) research. It occurs to me that a lot of people who are against stem cell research don't know what they are protesting about. The authors provide a history of cloning, as well as information about stem cells.The real fun starts when the authors attack various myths about cloning. Obviously, too many people have been watching too many bad movies and television programs. Remember they're just fictional stories. If, somehow, scientists manage to clone you. Twenty years from now your clone isn't going to kill you. Among the myths explored and exploded are that a clone will know everything you know and will act as you do, that heads which are cut off can be kept alive, and that a clone has no belly button (肚脐). Many of the myths are ridiculous but many people believe them.Kurpinski and Johnson also detail some bio-improvements "that really work". You see, genes can be controlled to help you sleep better and become smarter, healthier, and taller. Well... not exactly you, but future generations.If you do wind up in a battle with your own clone, who will be considerably younger than you, remember that it is not you and that it doesn't know what you know.46. Many bioengineering experts in the movies are .A. humorousB. wealthyC. seriousD. crazy47. We can learn from the passage that biotechnology .A. has been banned in many countries around the worldB. is being used to improve one's intelligence right nowC. can help improve the physical condition of future generationsD. is sure to cure any disease in the near future48. According to the passage, a clone of you .A. will want to kill youB. knows whatever you knowC. has no belly buttonD. will be younger than you49. The passage was written mainly to .A. predict the future of cloningB. introduce two bioengineering expertsC. review a book on cloningD. protest against movies about cloning BIn 1822 Gregor Mendel was born on a farm in Austria. His father found that Mendel was interested in plants. He knew that his son was clever, and he sent Mendel to high school. At that time few people attended high school, and those who did lived there. However, since his father could not give him enough money, he always felt hungry. Luckily, the other students always gave him food from their plates.Later Mendel became a monk (和尚) and continued his studies. He took care of the gardens at the temple where he and the other monks lived. He did experiments with pea(豌豆) plants for eight years. He wanted to prove that parents passed features to their children. Around 1860 Mendel discovered that plants have recessive and dominant genes (隐性和显性基因).He grew a tall pea plant with a short pea plant. Every one of the first generation(培育后代) of four pea plants was tall. This meant that tall was the dominant gene. Yet in the next generation of four pea plants, one plant was very short. The recessive short genes it received from both of its parent plants had made it short.From these experiments, he understood: Dominant genes showed up the most often in the children. Recessive genes only showed up sometimes and only when both parents carried the gene for the features.To share his finding with others, he wrote a paper. But during his lifetime no one cared about what he had discovered. At the time of his death, he still felt very sad.Finally, his important discovery was accepted in 1990. We know that both plants and animals have genes and that genes play a major role in how we look, how we act, and whether or not we are likely to get certain diseases.50. Which of the following is the correct order of the events mentioned in the text?a. Gregor Mendel became a monk.b. Gregor Mendel went to high school.c. Gregor Mendel did lots of plant experiments.d. Gregor Mendel wrote a paper to share his discovery.A. b-c-d-aB. b-a-c-dC. a-c-b-dD. a-d-b-c51. The third paragraph mainly tells us .A. there are different kinds of pea plantsB. where pea plants should be grownC. how Mendel made his discoveryD. Mendel liked to do experiments52. Why did Mendel feel sad at the time of his death?A. His father died from disease.B. His discovery wasn't accepted.C. He couldn't continue his research.D. He couldn't realize his great dream.CThe cloning technology has aroused heated discussions among people. Some of them speak highly of the technology by claiming that it offers a way for human beings to conquer their own genetic defects.★ Others consider it as an ogre (怪物) who will destroy us all in the end.FOR◆Equal importance is that women who are single could have a child, using cloning instead of artificial insemination(受精). Cloning could also provide a copy of a child for a couple whose child had died.◆Another goal of cloning is to produce livestock(家禽) with ideal characters for the agricultural industry and to be able to manufacture biological products such as proteins for humans.◆Cloning could be used in various ways to benefit the lives of humans.◆It may provide a way for completely sterile individuals to reproduce. It may provide a way for homosexual couples to reproduce themselves. It probably will provide a valuable basic research and possible spin off technologies related to reproduction and development.◆Cloning would also mean that organs could be cloned, so it would be a source of perfect transplant organs. This surely would be immensely beneficial to millions of unfortunate people who are expected to lose their lives due to failure of single(or more) organ(s).AGAINST◆Cloning would intervene with the normal cycle of life. There would be a large number of identical(相同的) genes, which minimize(使减小) the chances of mutation(变异), and, in turn, evolution—the fundamental reason how living things naturally adapt to the ever—changing environment.◆With genetic engineering and human cloning it is possible to use these in the arsenal(兵工厂) of ethnic cleansing(清洗) inequality in our society, which would be the beginning of many wars.◆Another argument against cloning is that it would be available only to the wealthy and therefore would increase social inequality.◆If the technology were to be so that scientists could transfer human genes into animals and vice-versa, which would heighten the danger of developing zoonoses, diseases that are transmitted from animals to humans. It could create a worldwide catastrophe that no one would be able to stop.◆Genetic engineering will cause unseen disasters spiraling our world into chaotic darkness.◆Cloning dead loved ones will not bring them back; they may look like them, but they will have a different personality.53.

What does the underlined word "these" in the part of AGAINST refer to?A. Large number of identical genes.B. Genetic engineering and human cloning.C. Ethnic cleansing inequality in our society.D. The wealthy and therefore social inequality.57. Which of the following is true according to the passage?A. Cloning could also produce biological products such as proteins for livestock.B. Healthy organs could be cloned to transplant into unfortunate people.C. A large number of identical genes would widen the chances of mutation.D. Genetic engineering will cause unseen disasters and light the world.DYou Are What You EatGenetic(基因的) engineering is the scientific change of the genetic material in a living organism. It allows scientists to identify specific genes, to remove them from an organism's chromosomes(染色体), improve them, analyze them, and possibly clone them, and to then reinsert the changed gene into the original organism, or a completely different organism. Unlike traditional breeding(繁殖), where a desired quality would be bred within the same species, genetic engineering can insert desired ones into organisms of different species. Wow… Did you catch that?Genetic engineering creates many positive contributions to agriculture. For example, by genetically engineered (GE) foods, anti-cancer agents, minerals and vitamins can be increased. Improved taste, shelf life, and better transport are all possible. Also, GE plants can increase pest and bacterial resistance, therefore, making the food safe for consumers.But some argue that the possible negative effects outweigh the positives, and critics are starting to voice their concerns. Unlike Europe, in the United States labeling is not required on genetically engineered foods or on foods that contain genetically engineered products. Most Americans do not realize that they are, in fact, eating GE foods. The public is also concerned about the unknown health risks. With limited understanding of genes, scientists cannot predict possible effects. Because most genes introduced into GE plants come from sources not introduced into the human body, it is impossible to know if they will cause reactions. Moreover, due to the lack of labeling, if allergies develop, it will be extremely difficult to find the origin of them.There is also a major moral question in many minds. For many, the conflict is not if it is safe or not, but it disturbs them because it is unnatural and unnecessary. We are currently producing one and a half times the amount of food needed to feed the world, yet one in seven people are starving. GE food is unnecessary, and fails to address the root of hunger. Many believe that the only people who will benefit are the corporations that produce it.Scientists cannot foresee the possible effects of GE foods, yet we eat them every day without even knowing it. We already have enough food, so why create more that could be potentially harmful to us, to the Earth and to all wildlife? I think that the benefits are amazing, but until we know for sure how these foods will affect us, they are not worth the risk.58. According to the passage, traditional breeding is different from genetic engineering in that .A. traditional breeding changes the genes in the same speciesB. traditional breeding changes the genes in different speciesC. traditional breeding takes place within the same speciesD. traditional breeding is more scientific59. "The lack of labeling" in Paragraph 4 indicates .A. information concerning gene sources is unavailable to customersB. it is currently possible to find the origins of some allergiesC. scientists try to hide potential dangers from customersD. the US government is responsible for GE food60. According to Paragraph 5, GE food is unnecessary because .A. it won't help solve the problem of hunger in the worldB. there are potential dangers in producing GE foodC. we're now producing more food than beforeD. customers will benefit from GE food61. What is the author's attitude towards genetic engineering?A. Welcoming.B. Disapproving.C. Unconcerned.D. Optimistic. 答案一、单词拼写(依据中文提示拼写单词)1. procedure2. owed3. merely/only4. altogether5. condition6. compulsory7. media8. resisting二、单词拼写(单句首字母填空)9. bound10. adores11. vain12. bother13. struck14. objected15. retires三、单项选择16.

The vehicle-named the Transition–has two seats, four wheels and wings that fold up so it can be driven like a car. TheTransition, which flew at 1,400 feet for eight minutes last month, can reach around 70 miles per hour on the road and 115 in the air. It flies using a 23-gallon tank of gas and bums 5 gallons per hour in the air. On the ground, it gets 35 miles per gallon.Around 100 people have already put down a $10,000 deposit to get a Transition when they go on sale, and those numbers will likely rise after Terrafugia introduces the Transition to the public later this week at the New York Auto Show. But don’t expect it to show up in too many driveways. It’s expected to cost $279,000.And it won’t help if you’re stuck in traffic. The car needs a runway.Inventors have been trying to make flying cars since the 1930s, according to Robert Mann, an airline industry expert. But Mann thinks Terrafugia has come closer than anyone to making the flying car a reality. The govemment has already permitted the company to use special materials to make it easier for the vehicle to fly. The Transition is now going through crash tests to make sure it meets federal safety standards.Mann said Terrafugia was helped by the Federal Aviation Administration’s decision five years ago to create a separate set of standards for light sport aircraft, which are lower than those for pilots of larger planes Terrafugia says an owner would need to pass a test and complete 20 hours of flying time to be able to fly the Transition, a requirement pilots would find redatively easy to meet.1.What is the first paragraph mainly about?A.The basic data of the Transition.B.The advantages of flying cars.C.The potential market for flying cars.D.The designers of the Transition.2.Why is the Transition unlikely to show up in too many driveways?A.It causes traffic jams.B.It is difficult to operate.C.It is very expensive.D.It bums too much fuel.3.What is the government’s attitude to the development of the flying car?A.CautiousB.Favorable.C.Ambiguous.D.Disapproving.4.What is the best title for the text?A.Flying Car at Auto ShowB.The Transition’s Fist FlightC.Pilots’Dream Coming TrueD.Flying Car Closer to Reality四、七选五How to Care for a Pet FishTaking care of a pet is a big responsibility, so you should make sure you learn all about your pet before bringing it home. ①______ That' s because fish can give them a good idea of whether or not they'll be able to take care of a more complicated(复杂的) pet later on.First, choose what types of fish. ②______ They are easier to raise and give you enough experience to take care of fish and their tanks(水箱). Some kinds of fish do not get along with others, so you'll need to choose what kinds to buy.Next, make sure you have all of the necessary supplies. Fish need a fish tank. Make sure it is big enough for the number of fish. Fish tanks need a light and some machines to keep the water clean and at a comfortable temperature. ③______Now you can set up your aquarium(水族馆). Wash sand and decorations( 装饰物) clean and fill the bottom of the tank with them. ④______ Follow the instructions on the heater to heat up the water to the temperature your fish will need. Make sure your light is ready to go, too!⑤______ The pet store keeper can teach you how to make your fish get comfortable before you put them into your aquarium. Once the fish are in the tank, you have to watch them closely to make sure they don't get sick. Feed them in small amounts a few times a day. You will have to change some of the water at least once a week.A. Then, fill the tank with water.B. You are ready to pick up your fish.C. Many kids have fish as their first pet.D. You need some beautiful tanks to change.E. Be sure to get food for your fish as well.F. Freshwater fish are the best fish to start with.G.

Ⅰ阅读理解ASeven years ago，back in 2010，some reports covered a story that the worl d’s longest railway tunnel was under construction in Switzerland.At that point it had already been under construction for over a decade.It had been voted to be built nearly a quarter of a century ago！The idea to build it could date back to nearly 70 years ago—about as old as some of your grandparents!Yesterday，it was finally ready!It’s about 35 miles long and runs 7，500 feet beneath the Swiss Alps，a famous mountain range in Switzerland.It even runs under an old tunnel that was there before.It took a total of 17 years to build at a cost of$12 billion！28 million tons of rock were dug.Two million truckloads of earth were removed!The tunnel connects northern and southern Europe.The opening of this tunnel was such a big deal that the Germany’s leader，Chancellor Angela Merkel，France’s president，Francois Hollande，and Italy’s prime minister，Matteo Renzi，were all there to celebrate，as was Austria’s chancellor Christian Kern.It’s called the Gotthard Base Tunnel.Eventually，325 freight and passenger trains will go through the tunnel，relieving a lot of traffic on the roadways there and making it a more environmentally friendly option.The Gotthard Base Tunnel is a wonder of engineering and makes us want to visit it!【解题导语】本文介绍了戈特哈德隧道的建成及其相关情况和由此带来的意义。
