AIt all started at the beginning of fifth grade.At first,Carmen wasn't really sure what was happening.In class,she had to squint（眯眼）to see the blackboard clearly.As it got worse,she became more and more worried.It was important for her to see the notes and homework the teacher wrote on the board.In class.she asked for a desk that was closer to the blackboard.One day,her teacher said,“Carmen,I've noticed you squinting a lot.Are you having troubl e seeing the board?”Carmen shook her head.“I'm fine,Mrs Cruz”.At home,she had to sit closer and closer to the television in order to see the picture.Her mother noticed her squinting as she watched her favorite shows.“Tomorrow I will take you to see a doctor,”she said firmly.Three days later,Carmen had new glasses.She was told to wear them all the time.“A ll of the kids at school will think I am a nerd（书呆子）.”she sa id.“You look just as beautiful with those glasses on as you do without them,”her mother said.But C armen didn’t believe her.The next day,Carmen kept the glasses in her pocket as she walked into the schoolyard.Suddenly,she heard her friend Theresa shout.“What’s wrong?”she asked.“My silver ring is gone!”Theresa cried.Carmen could tell that Theresa was very upset.They all looked for the ring in the grassy area of the playground.Carmen realized that she could search better if she could see better.She took the glasses out of her pocket and put them on.Everything looked so different!So clear!She looked down at the ground and a glimmer（微光）of silver caught her eye.It was the ring.“Here it is,”she shouted.“Thanks Carmen,”Theresa said.“Hey,I didn’t know you wore glasses.They look great!” “Thanks,”Ca rmen replied shyly.As they walked back toward the school building,two more girls from her class complimented（赞美）her glasses. Carmen smiled.“Maybe wearing glasses won’t be so bad after all.”she tho ught.1.After she put her glasses on in school,Carmen felt .A.sadB.pleasedC.disappointedD.surprised2.Which of the following statements best describes Carmen?A.She liked to overcome her fears to help her friends.B.She cared more about herself than her friends.C.She didn't worry about what other people thought of her.D.She didn't care how well she did in school.3.What can we infer from the last two paragraphs?A.Other girls expected to have new glasses.B.Carmen hoped to receive more comments on her glasses.C.Wearing glasses made Carmen look beautiful.D.Carmen would get used to wearing glasses.4.The purpose of the text is to tell readers .A.how we should protect our eyesB.things are not always as bad as we expectC.we should never make fun of othersD.it is necessary to give a hand to those in troubleBElephants are unbelievable creatures.They feel sad over the bodies of dead members,and can even recognize themselves in a mirror.And there's an old saying “Elephants never forget”.In the wild,an elephant's memory is the key to its survival.Science has proven that elephants have great memories.In 2007,researchers at the University of Saint Andrews in Scotland placed urine samples（尿液样本）in front of female elephants at the Amboseli National Park in Kenya.The elephants “acted up” when they smelled urine that didn’t come from an elephant in their group.The researchers concluded that elephants could recognize and track as many as 30 of their companions.Elephants don't just remember companions whom they've spent a long time with.A pair of elephants has shown that these animals can recognize other friendly elephants even when they had only spent short periods of time together.An elephant named Jenny became very lively when a new elephant named Shirley arrived.After looking into the animals' backgrounds,workers found that the two had performed in the same circus for only a few months.Their excellent memories help elephants stay alive in ways that go beyond just recognizing dangers.Matt Lewis, an officer with the World Wildlife Fund,tells that one of the best examples of elephants' memory comes from desert-adapted elephants,where the elephant leaders remember where reliable water can be found and are able to guide their groups to water over very tong distances,and over the period of many years.However,an elephant's amazing memory comes only with age and experience.Unluckily,when the leader of a certain group of elephants dies,the information dies,leaving the rest of the group at a disadvantage,and doing great harm to the group as a whole.5.Why are elephants unbelievable creatures?A.Because they are too clever for words.B.Because they have great memories.C.Because they feel sad over the dead members.D.Because they can recognize themselves in a mirror.6.We can learn from Paragraph 2 that .A.only female elephants have good memoriesB.every elephant has as many as 30 companionsC.smelling urine is a way of proving elephants' good memoryD.the elephants like to smell the urine samples7.We can conclude from the passage that .A.elephants' memory can be improved by trainingB.the elephant leader has the best memory in the groupC.elephants' good memory only helps to avoid threatsD.all desert elephants can remember water places for many years8.What can be the best title for the passage?A.Elephants Never ForgetB.Elephants' Memory Is The BestC.The Elephant-The Cleverest AnimalD.Elephants Can't Live Without MemoryCBeauty is only a short-time surface quality,and some beauty products can cause lasting damage that goes far below the surface of the skin.But people,especially women,will risk a lot on beauty.In some African countries,some women take health risks,trying to use products that lighten the skin.The World Health Organization says that 25 percent of African women nearly use skin-lightening products every morning and evening.These products can contain some harmful chemicals which can cause cancer and possibly other physical damage to the skin.They can actually burn the eyes and skin.A common beauty shop in Dakar has many kinds of skin-lightening products.Shop worker Adam advises her visitors to avoid the strong products that promise fast results.She herself uses a product that is made not from chemicals,but from carrots.She says that it is a personal choice and that no one pressures her.Women in Senegal lighten their skin for the same reason as women all over the world make changes to their appearance.They want to look beautiful,to find a husband,or to stand out in a crowd.But some products are so strong that they must be mixed with others before they are used.One such product is called "Day Before the Wedding".This thinking troubles Senegalese filmmaker Khardiata Pouye Sall.So she made a film This Color That Bothers Me about the subject of skin lightening.Ms Sall used the most frightening photos and she hoped that women would see the dangers.It was hard for her to understand why a woman would tell herself that dark skin is not beautiful.It is in their heads.Maybe they want toplease others.She thinks the government needs to better control the marketing and sale of skin lighteners.But she adds education is the best way to persuade people against using them.9.What do we know about the chemicals in some beauty products?A.They come from carrots.B.All of them can cause cancer.C.They may cause some serious damage to women.D.They can lighten women’s skin very quickly.10.It can be inferred from Paragraph 3 that Adam .A.is mean to othersB.has very good skinC.looks really beautifulD.cares about her customers11.Why do women in Senegal lighten their skin?a.To look beautiful.b.To have a chance for work.c.To run for stars.d.To find a husband.e.To stand out in a crowd.A. abcdB.bcdeC.adeD.acd12.According to Ms Sall,what should be done to stop people from using skin lighteners?A.People should be educated on the dangers of using them.B.Producing skin lighteners should be stopped.C.The most frightening photos should be shown to people.D.People should be told that people with dark skin can have a good fortune.DAmerican scientists have for the first time taken stem cells（干细胞）from human embryos（胚胎）that are genetic copies（基因复制）of living people.The goal is to create better treatments for disease.But the work has led to heated discussions about making genetic copies or cloning.Cloning a human being is not allowed in more than twelve states in America.Most scientists are against it,but some medical researchers are performing what is called “therapeutic clonin g” to t ry to fight disease.Still,that method is not allowed in seven states.One state where “therapeu t ic cloning” is allowed is Oregon.That is where researchers at Oregon Health&Science University in Portland were able to put human DNA into human eggs.They produced embryos that were genetically the same as those produced by people who had given their DNA to the research project.The researchers then took stem cells from the embryos.These cells are called “master cells”. Scientists know how to use chemicals to cause master cells to develop into any tissue in the body.The idea is that doctors could use tissues created this way to replace diseased organs.The new part would be a genetic match of the person who receives it,and there would be no danger that the sick person's body would not accept the new part.Alta Charo,a researcher at the University of Wisconsin Law School,believes it is too soon to say whether the use of embryonic stem cells for personalized medicine would become common.Scientists could in fact find other less questionable sources of stein cells.However,she supports the use of stem cells to treat disease.13.Which of the following statements is TRUE?A.Stem cells can be used in medical treatment.B.Everyone supports the idea of making genetic copies.C.America is the first country that has taken stem cells from embryos.D.Human embryos are taken from stem cells.14.What is the advantage of using the new tissue created by cloning?A.The new tissue would be accepted by the doctor.B.The new tissue is very good and everyone can use it.C.The new tissue would cost a little so that everyone can afford it.D.The new tissue would be suitable for the person receiving it genetically.15.What is the probable attitude of Alta Charo towards the use of embryonic stem cells?A.SupportiveB.ConcernedC.UninterestedD.Negative笫二部分：英语知识运用（共两节，满分50分）第一小节完形填空（共20小题；每小题1.5分，满分30分）阅读下面短文，从短文后各题所给的四个选项（A、B、C和D）中，选出可以填入空白处的最佳选项，并在答题卡上将该项涂黑。
