Some pare nts canun dersta nd that wish, but it must first be recog ni zed that the copy would be a new baby and not the lost child.Here liesthe_difficulty,_for the sad parents are seeking not a new baby but a retur n of the dead one. Since the origi nal wouldbefon dly remembered as hav ing particular tale nts and in terests, would not the pare nts expect the copy tobe the same? It ispossible, however, that the copy would develop quite differently. Is it fair to the new child to be placed in family withsuch unn atural expectati ons?Copy ing is also suggested as a means by which pare nts can have the child of their dreams. Couples might choose to have a copy of a film star, baseball player or scie ntist, depe nding on their in terests. But because pers on ality is onlypartly the result of gen etic in herita nee, con flicts would be sure to arise if the cloned child failed to develop thesameinterests as the original. What if the copy of Einstein shows no in terest in scie nee? Or the baseball player tur ns to acti ng? Success_also_depe nds_o n_fortune. What if the child does not live up to the hopes and dreams of their pare nts simply because of bad luck?Every child should be wan ted for itself, as a pers on. In making a copy of on eself or some famous pers on, a pare ntis purposely specify ing the way he or she wishes that child to develop. In rece nt years, particularly in the U. S., much importa nee has bee n placed on the right of in dividuals to reproduce in ways that they wish. So I suggest there should be a greater n eed to con sider the in terests of the child and to reject these suggested uses of cloning.11. The underlined part “the difficulty ” in Paragraph 1refers to _______ .A. cloning a baby is difficultB. it's difficult to give birth to a new babyC. the dead child can't come back aga inD. the cloned baby can't replace the lost child 12. According to the passage, one of the reasons whycouples usually decide to clone babies is _______ A. to bring back a child killed unfortunately B. to excha nge their childre nC. to develop the same in terests as their childD. to succeed in making fortune13. The sentence “ Success also depends on fortuimplies that _______ . A. the result may be un predictableB. the child does not live up to the pare nts' hopesC. the cloned child fails to develop the same interest as origi nalD. the baseball player tur ns to act ing 14. We CAN'T conclude thatobservati on made by the author.A. it's important to consider the interests of therather tha n the suggested uses of cloningB. pare nts can't expect to get the lost child back by cloninga new babyC. much importanee should be placed on the right of pare nts to reproduce babies in ways that they wishD. every child should be wan ted as a unique in dividual B Ride With The Leadernetheaccording to thechildCitySights NY has become the recog ni zed leader in NY C's sightsee ing.We operate the first top- deck-seating-only buses.

services from the mainland have come into use.A.reliableB.permanentC.regularD.frequentⅠ.阅读理解In 2004，when my daughter Becky was ten，she and my husband，Joe，were united in theirdesire for a dog.As for me，I shared none of their canine lust.“But why？”they pleaded.“Because I don’t have time to take care of a dog.”“But we’ll do it.”“Really？You’re going to walk the dog？Feed the dog？Bathe the dog？”“Yes，yes，and yes.”“I don’t believe you.”“We will.We promise.”They didn’t.From day two (everyone wanted to walk the cute puppy that first day)，neither thought to walk the dog.While I was slow to accept that I would be the one to keep track of her shots，to schedule her vet appointments，to feed and clean her，Misty knew this on day one.As she looked up at the three new humans in her life (small，medium，and large)，she calculated，“The medium one is the sucker in the pack.”Quickly，she and I developed something very similar to a Vulcan mind meld(心灵融合).She’d look at me with those sad brown eyes of hers，beam her need，and then wait，trusting I would understand—which，strangely，I almost did.In no time，she became my fifth appendage(附肢)，snoring on my home-office couch as I worked，cradling against my feet as I read，and splaying across my stomach as I watched television.Even so，part of me continued to resent walking duty.Joe and Becky had promised.Not fair，I’d balk(不心甘情愿地做) silently as she and I walked.“Not fair，” I’d loudly remind anyone within earshot upon our return home.Then one day—January 1,2007，to be exact—my husband’s doctor uttered an unthinkable word：leukemia(白血病).With that，I spent eight to ten hours a day with Joe in the hospital，doing anything and everything I could to ease his discomfort.During those six months of hospitalizations，Becky,12 at the time，adjusted to other adults being in the house when she returned from school.My work colleagues adjusted to my taking off at a moment’s notice for medical emergencies.Every part of my life changed；no part of my old routine remained.Save one：Misty still needed walking.At the beginning，when friends offered to take her through her paces，I declined because I knew they had their own households to deal with.As the months went by，I began to realize that I actually wanted to walk Misty.The walk in the morning before I headed to the hospital was a quiet，peaceful time to gather my thoughts or to just be before the day’s medical drama unfolded.The evening walk was a time to shake off the day’s upsets and let the worry tracks in my head go to white noise.When serious illness visits your household，it’s not just your daily routine and your assumptions about the future that are no longer familiar.Pretty much everyone you know acts differently.Not Misty.Take her for a walk，and she had no interest in Joe’s blood counts or bone marrow test results.On the street or in the park，she had only one thing on her mind：squirrels！She was so joyous that even on the worst days，she could make me smile.On a daily basis she reminded me thatlife goes on.After Joe died in 2009，Misty slept on his pillow.I’m grateful—to a point.The truth is，after years of walking，I’ve come to enjoy my walks with Misty.As I watch her chase after a squirrel，throwing her whole being into the here-and-now of an exercise that has never once ended in victory，she reminds me，too，that no matter how harsh the present or unpredictable the future，there’s almost always some measure of joy to be extracted from the moment.1.Why didn’t the writer agree to raise a dog at the beginning of the story?A.She was afraid the dog would get the family into trouble.B.It would be her business to take care of the dog.C.Her husband and daughter were united as one.D.She didn’t want to spoil her daughter.2.Which of the following is the closest in meaning to “The medium one is the sucker in the pack.”(Paragraph 3)?A.The middle-aged person loves me most.B.The medium-sized woman is the hostess.C.The man in the middle is the one who has the final say.D.The woman is the kind and trustworthy one in the family.3.It can be inferred from Paragraph 3 that .A.Misty was quite cleverB.Misty could solve math problemsC.the writer was a slow learnerD.no one walked Misty the first day4.The story came to its turning point when .A.Joe died in 2009B.Joe fell ill in 2007C.the writer began to walk the dogD.the dog tried to please the writer5.Why did the writer continue to walk Misty while Joe was in hospital?A.Misty couldn’t live without her.B.Her friends didn’t offer any help.C.The walk provided her with spiritual comfort.D.She didn’t want Misty to be others’ companion.6.What is the message the writer wants to convey in the passage?A.One should learn to enjoy hard times.B.A disaster can change everything in life.C.Moments of joy suggest that there is still hope ahead.D.People will change their attitude towards you when you are in difficulty.Ⅱ.佳作背诵(计划与愿望)请认真阅读下面我国某市十年来出境旅游(outbound tourism)目的地变化的相关文字及柱状图，并按照要求用英语写一篇150词左右的文章。

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。

regarded My Mortal Enemy as somewhat of an enigma.Written in only a few months during the early spring of 1925 and published in 1926，Willa Cather’s shortest novel was sandwiched in between The Professor’s House(1925) and Death Comes for the Archbishop(1927).While the subject matter of these latter two works can be traced to Cather’sexperience in the desert Southwest，My Mortal Enemy seemingly has nothing to do with these subjects or her Nebraska roots；it appears to have come out of nowhere，puzzling those who have tried to fit this rather irregular work into a logical progression of Cather’s artistic development.The question of what caused Cather to write such a novel at this point in her career，for example，has still not been answered definitively.One commonly held hypothesis(假说) was first voiced by Marcus Klein，who in his 1961 introduction to the novel wrote that for Cather，“The story of Myra Henshawe must have been a personal crisis.” Klein，though，acknowledged that he could not prove his theory，“because there is available no record other than the novel.”Emmy Stark Zitter has recently argued that in My Mortal Enemy and Sapphira and the Sla v e Girl (1940) Cather exercises the autobiographical impulse(冲击) by putting details of her own life into her fiction，but，like Klein，she is unable to name which “details” of her life Cather drew on in writing My Mortal Enemy.As hinted(暗示) in the above statements by Klein and Zitter，much of the general uncertainty about the meaning of My Mortal Enemy can be traced to the absence of a persuasive theory as to who the real-life models for the novel’s characters were and what Cather’s relationship to them was.Cather herself wrote in a 1940 letter that，in James Woodress’s paraphrase，“she had known Myra’s real-life model very well，and the portrait drawn in the story was much as she remembered her”；Cather also added that the woman had died fifteen years before My Mortal Enemy was published，and that many relatives of this model later wrote to her to say that they recognized the “real”Myra from her description in the novel.Given such hints and Cather’s liking for drawing on her experiences in Nebraska for characters，settings，and plots，it is quite understandable that scholars have thus looked to Red Cloud and Lincoln for possible sources of the people and events depicted in My Mortal Enemy.In light of the evidence presented in this article，though，I believe that Cather intended her comments about the model for Myra Henshawe to serve as red herrings(转移注意力的言语) that would protect her relationship with the couple who were the prototypes(原型) for the Henshawes，both of whom were still alive in 1925.Mark Madigan has recently confirmed how Cather in 1905 had to hold off publishing The Profile(《侧画像》) because of fears that the main character might recognize herself and commit suicide，and twenty years later Cather would have been well aware of how her description of the Henshawes might have affected both the real-life wife (who died in 1929) and husband (who died in 1949) if they had recognized themselves.It is my argument that the Henshawes were modeled after people Cather knew not in Nebraska but rather in New York：S.S. and Hattie McClure.Myra’s uncle，John Driscoll，was modeled after Hattie’s father，Professor Albert Hurd.Possibly most important，identifying the Henshawes as the McClures allows us to moreconclusively identify Cather herself with Nellie Birdseye.Nellie and Cather，both Midwestern onlookers and recorders，experienced four distinct stages in their relationships with the Henshawes and the McClures (especially with S.S.).My Mortal Enemy，I believe，was an extended attempt by Cather to deal with certain aspects of her own past and to move on in a world stripped of romantic illusion.1.The underlined word “enigma” in Paragraph 1 means “”.A.adaptationB.abstractC.best-sellerD.mystery2.Cather didn’t have My Mortal Enemy published immediately .A.so as not to annoy the relatives of the prototype for MyraB.for fear that the prototype for Myra should be badly hurtC.because she meant to polish it by adding some new materialD.because she was forbidden to do so by the real-life couple3.We can infer from the passage that .A.Myra Henshawe is particularly true to her prototypeB.Cather had a good relationship with the real-life modelC.the writer considers My Mortal Enemy as a great workD.scholars will put an end to their argument about the novel4.In the passage，the writer .A.restored the truth behind MyraB.presented his own hypothesisC.made a revision to Zitter’s ideaD.renewed part of Klein’s fiction5.The proper title for the passage is “”.A.Uncovering Cather’s Personal SecretB.Unlocking the Scholars’ ImaginationC.Unfolding the Plot of My Mortal EnemyD.Unmasking Cather’s “Mortal Enemy”Ⅱ.佳作背诵(日常活动)请认真阅读下面短文，并按照要求用英语写一篇150词左右的文章。

find it in the dictionary.It means that as a human being you take responsibility for your own life.Look at the word responsibility：ability to choose your response，response-ability.Effective people are proactive because they take responsibility.Their behaviour is a product of their own decisions，based on values，rather than being a product of their own conditions，based on feelings.For instance，you are planning a picnic with your family.You’re excited.You have all the preparations.You’ve decided where to go，and then it becomes stormy，killing your plan.Proactive people carry weather within them.They realize what their purpose really was，and they creatively have a picnic elsewhere even if it’s intheir own basement with some special games，and make the best of that situation.The opposite of being proactive is to be reactive.Reactive people would say，“What’s the use？”“We can’t do anything.”“Oh，this is so upsetting after all of our preparations and arrangements.”They try to persuade the people around them and usually the picnic will be cancelled.Being proactive is really just being true to your human nature.Your basic nature is to act，and not to be acted upon.That’s true，despite widely accepted theories of determinism used to explain human nature.Determinism says that you don’t really choose anything and that what you call choices are nothing more than automatic responses to outside conditions.The language of reactive people is like：“I can’t.”“Don’t have time.”“I have to.”“I must.” The whole spirit of that language is the transfer of responsibility.They think things are determined by their environment，or by their conditions，or by their conditioning or their genetic makeup.Psychologically，people who believe they are determined will produce the evidence to support the belief，and they increasingly feel victimized and out of control.They’re not in charge of their life at all.On the contrary，a proactive person exercises the free will，the freedom to choose the response that best applies to his values.In that way，he gains control over the circumstances，rather than being controlled by them.21.According to the passage，a proactive person’s behaviour can result from .A.the environmentB.an inner beliefC.the genetic makeupD.a temporary feeling22.When a picnic plan is threatened by a sudden storm，reactive people will probably .A.have the picnic as plannedB.make the best of the picnicplain and give up the picnicD.find somewhere else for the picnic23.What does “carry weather within them” in the second paragraph probably mean?A.Manage to improve the weather.B.Give in to the weather passively.C.Stress the influence of the weather.D.Find a solution to the weather problems.24.It can be concluded from the passage that determinists .A.accept things passivelyB.are in

threatened species under the U.S.Endangered Species Act as populations have declined.Meanwhile，snow geese are booming near the western Hudson Bay，and there are in fact too many of them.Their eggs can be a good food source.The geese nest on tundra(冻原，苔原) that some bears have retreated to.“Over 40 years，six subadult(接近成年的) male bears were seen among snow goose nests，and four of them were sighted after the year 2000，”says Robert Rockwell.“I’ve seen a subadult male eat goose eggs whole or press its nose against the shell，break it，and eat the contents.”Ice is melting，on average,0.72 days earlier each year in the region studied.Snow geese are hatching eggs about 0.16 days sooner each year，according to Rockwell and his graduate studentLinda Gormezano.Current trends indicate that the arrival of polar bears will correspond to the average hatching period in 3.6 years，and egg consumption could become a viable option，which the researcher concluded in a statement released today.A polar bear，the largest land carnivore(食肉动物)，would need to consume the eggs of 43 nests to replace the energy gained from the average day of hunting seals，but Rockwell and his colleagues figure that while many polar bears may starve in coming years，the resourceful animals just might survive disappearance.Polar bears survived a warm period about 125,000 years ago，when sea level was 12 to 18 feet higher than it is now and trees lived above the Arctic Circle，the scientists point out.“They’ve been through the warm period before，” Rockwell said.The polar bears’ potential movement to a diet of more eggs brought to mind a quote by Ilkoo Angutikjuak，an Inuit who lives in the Canadian province of Nunavut，in the February 2008 issue of Natural History magazine，Rockwell said.Angutikjuak said：“The animals will adapt.I’ve heard that because they depend on sea ice，polar bears will disappear，but I don’t believe it.They are very adaptable.As the sea ice changes，polar bears might get skinnier and some might die，but I don’t think they will disappear.”21.What can we infer about the polar bears from the passage?A.They have a strong ability to survive.B.They tend to withdraw from the tundra.C.Their hunting skills have declined sharply.D.Their main food source is goose eggs now.22.What does the underlined word “viable” in Paragraph 4 mean?A.Challenging.B.Practical.C.Destructive.D.Outdated.23.Which of the following statements does Rockwell agree with?A.Goose eggs are adequate for polar bears.B.Polar bears’ food variety is relatively limited.C.Polar bears might adapt to the global warming.D.Many polar bears will starve to death in future.24.What’s the passage mainly talking about?A.Polar bears pose a major threat to the geese.B.Polar bears can live in harmony with the geese.C.Polar bears are

Unit 2 cloning learning about language课时作业I．阅读理解ABrushing your teeth regularly could help to prevent bowel(肠) cancer，a study suggests.This is because the mouth bacteria that cause bleeding gums(牙龈) can travel via the blood to the bowel where they could result in cancer or worsen existing tumours(肿瘤).The bug fusobacterium(梭杆菌) has been found to be hundreds of times more common in cancerous tumours than in normal cells.Now researchers have found that the bacteria can make pre-cancerous growths in the bowel turn cancerous.They can also make any existing tumours in the bowel grow larger.Scientists are doing research on how the bacteria make their way to the bowel through the blood stream.One theory is that it may happen if a person has bleeding gums.The researchers found that the bacteria have a protein that allows them to stick to sugar molecules attached to friendly growths called polyps(息肉) as well as cancer tumours in the bowel.The bacteria are anaerobic—they do not breathe oxygen—so are well suited to live in the bowel.After sticking to the polyps or tumours，the presence of the bacteria promotes their growth，according to the research.By targeting this process，the researchers believe that it may lead to new drugs to treat bowel cancer which around 1 in 20 of us will develop in our lifetimes.Co-author Wendy Garret，a professor at Harvard University said a greater understanding of the mechanism(机理)may help stop people developing cancerous tumours.She added，“More importantly，our findings suggest that the new drugs could potentially prevent these bacteria from worsening bowel cancer.”As well as worsening cancer，the bacteria have also been found to worsen the bowel condition ulcerative colitis(溃疡性结肠炎)，which in turn is also linked to cancer.So，the researchers warn that mouth health may be an indicator of other lifestyle factors linked to cancer.1.From the first paragraph，we can learn that .A.bowel cancer may be cured by brushing teeth regularlyB.scientists have found the reason for bowel cancerC.brushing teeth regularly helps you fight bad breathD.good mouth health has a good effect on preventing bowel cancer2.According to researchers，if a person suffers from bleeding gums，.A.bacteria may enter the bowel with blood and increase the risk of cancerB.the bug fusobacterium may decrease in the cellsC.measures must be taken to prevent blood flowing into bowelD.he should go to the dentist to have the teeth pulled out3.Chances are that through this research.A.people will get rid of the symptoms of bleeding gumsB.people will never suffer from bowel cancerC.scientists will develop more effective drugs to deal with bowel cancerD.scientists will find ways to stop fusobacterium worsening gums4.What’s the author’s purpose in writing this passage?A.To tell people not to worry about bowel cancer.B.To warn people of the danger of bowel cancer.C.To educate people about the ways to stop bleeding gums.D.To make people understand the importance of brushing teeth regularly.BThe domestic cat is a contradiction.No other animal has developed such a close relationship with human，while at the same time demanding and getting such self-determining movement and action.The cat manages to remain a tame(驯化的) animal because of the process of its upbringing.By living both with other cats(its mother and brother and sisters) and with human(the family that has adopted it) during its babyhood，it is considered to belong to both species.It is like a child that grows up in a foreign country and as a consequence becomes bilingual(双语的).The young cat becomes bimental.It may be a cat physically but mentally it is both feline(猫科的) and human.Once it is fully adult，however，most of its responses are feline ones，and it has only one major reaction to its human owners.It treats them as pseudo(假的) parents.This is rather different from the kind of bond that develops between human and dog.The dog sees its human owners as pseudo parents，as does the cat.On that score the process of attachment is similar.But the dog has an additional link.Canine(犬科的) society is group-organized；feline society is not.Dogs live in packs with tightly controlled status relationships among the individuals.There are top dogs，middle dogs，and bottom dogs and under natural circumstances they move around together，watching and following one another the whole time.So the adult pet dog sees its human family both as pseudo parents and as the dominant(主宰的) members of the pack，hence its well-known reputation for obedience and loyalty.Cats do have a complex social organization，but they never hunt in packs.In the wild，most of their day is spent in individual stalking(潜行追踪).Going for a walk with a human，therefore，has no appeal for them.And as for“coming to heel”and learning to“sit”and “stay”，they are simply not interested.Such drills have no meaning for them.Because of this difference between domestic cats and domestic dogs，cat-lovers tend to be rather different from dog-lovers.As a rule cat-lovers have a stronger personality bias(偏向) toward working alone，away from larger group.Artists like cats；soldiers like dogs.The highly-praised “group loyalty” phenomenon can’t be seen in both cats and cat-lovers.If you are a company person，a member of the gang，or a person picked for the military team，the chances are that at home there is no cat curled up in front of the fire.The ambitious politician，the professional athlete，these are not typical cat-owners.It is hard to picture football players with cats in their laps—much easier to imagine them taking their dogs for walks.Those who have studied cat-owners and dog-owners as two distinct groups report that there is also a gender bias.The majority of cat-lovers are female.This bias is not surprising in view of the division of labor obvious in the development of human societies.Prehistoric males became specialized as group-hunters，while the females concentrated on food-gathering and childbearing.This difference contributed to a human male’s “pack mentality” that is far less marked in females.Wolves，the wild ancestors of domestic dogs，also became pack-hunters，so the modern dog has much more in common with the human male than with the human female.The argument will always go on—feline self-sufficiency and individualism against canine camaraderie (友情) and good-fellowship.But it is important to stress that in making a valid point I have caricatured the two positions.In reality, there are many people who enjoy equally the company of both cats and dogs.And all of us，or nearly all of us，have both feline and canine elements in our personalities.We have moods when we want to be alone and thoughtful，and other times when we wish to be in the center of a crowded，noisy room.5.The primary purpose of the passage is to .A.advocate dogs as making better pets than catsB.distinguish the different characteristics of dogs and catsC.show the poor nature of dogs because of their loyalty characteristicsD.emphasize the role that human plays in the personalities of domestic pets6.According to the passage，the domestic cat is a contradiction because .A.it possesses the physical characteristics of both feline and humanB.it can’t be tamed and will always keep its wild habitsC.it refuses to be dominated despite living comfortably with humanD.although it plays the part of a pet，it really dominates human beings7.The underlined sentences in the second paragraph are used to stress .A.the disharmonious relationship between cats and human beingsB.a difference between cats and dogs that emphasizes cats’ natureC.the ignorance of dogs，which makes them more loyal petsD.the laziness of cats that keeps them from being pack animals8.The author suggests in the third paragraph that cat-lovers are than dog-lovers.A.less dependentB.less creativeC.more successfulD.more outgoing9.The fourth paragraph indicates that human females .A.preferred to raise domestic dogs to help with food-gatheringB.developed independent roles that required less group behaviorC.had to gather food because they were not strong enough to huntD.were negatively affected by the division of labor of human societies10.The underlined four sentences in the last paragraph provide .A.a summary of the points made earlierB.a reason for the statements made earlierC.an adjustment of the position taken earlierD.an example of the main points made earlierII.任务型阅读(共10小题；每小题1分，满分10分)请认真阅读下面短文，并根据所读内容在文章后表格中的空格里填入一个最恰当的单词。

tenth-grade English teacher.She was a teacher no one wanted because she was so 1 .She stood about five-foot-five，was very thin and wore her hair pulled back in a way that gave her a horsy 2 .She wore

those early days，many people have been involved in the process of developing a machine that could do the same thing more quickly and with greater efficiency.Charles Wiesenthal，who was born in Germany，designed and received a patent on a double-pointed needle that eliminated the need to turn the needle around with each stitch(缝合) in England in 1755.Other inventors of that time tried to develop a functional sewing machine，but each design had at least one serious imperfection.Frenchman Barthelemy Thimonnier finally engineered a machine that really worked.However，he was nearly killed by a group of angry tailors when they burned down his garment factory.They feared that they would lose their jobs to the machine.American inventor Elias Howe，born on July 9,1819，was awarded a patent for a method of sewing that used thread from two different sources.Howe’s machine had a needle with an eye atthe point，and it used the two threads to make a special stitch called a lockstitch.However，Howe faced difficulty in finding buyers for his machines in America.In frustration，he travelled to England to try to sell his invention there.When he finally returned home，he found that dozens of manufacturers were adapting his discovery for use in their own sewing machines.Isaac Singer，another American inventor，was also a manufacturer who made improvements to the design of sewing machines.He invented an up-and-down-motion mechanism that replaced the side-to-side machines.He also developed a foot treadle(脚踏板) to power his machine.This improvement left the sewer’s hands free.Undoubtedly，it was a huge improvement of the hand-cranked machine of the past.Soon the Singer sewing machine achieved more fame than the others for it was more practical，it could be adapted to home use and it could be bought on hire-purchase.The Singer sewing machine became the first home appliance，and the Singer company became one of the first American multinationals.However，Singer used the same method to create a lockstitch that Howe had already patented.As a result，Howe accused him of patent infringement(侵犯).Of course，Elias Howe won the court case，and Singer was ordered to pay Howe royalties(版税).In the end，Howe became a millionaire，not by manufacturing the sewing machine，but by receiving royalty payments for his invention.21.Barthelemy Thimonnier’s garment factory was burned down because .A.people did not know how to put out the fireB.Elias Howe thought Thimonnier had stolen his inventionC.workers who feared the loss of their jobs to a machine set fireD.the sewing machines couldn’t work finally22.Why did the court force Isaac Singer to pay Elias Howe a lifetime of royalties?A.Because the judge was against Singer for his surly attitude.B.Because Howe had already patented the lockstitch used by Singer.C.Because Singer had borrowed money from Howe and never repaid it.D.Because Singer and Howe had both invented the same machine.23.Which of the following would be
