So are some of his patients.You see, Dr. David, as many people call him, has some unusual patients. They aren’t the children he 36 sees ea ch day. They’re well, big, and hairy and sometimes weigh more than four hundred pounds. They’re 37 animals.On most days, Dr David tends to his human patients, teaching them how to care for their 38 . On some days, however, the Cincinnati Zoo calls with some special work for him to do. Since 1982, Dr. David has volunteered to perform dental surgery on many of the animals. This would be a 39 experience for most.Luckily, Dr. David feels differently. “I’m not 40 of the animals,” he says. “I have been around them so much that I’m used to them.”How does a children’s dentist find himself 41 the teeth of a black rhino or a monkey? For Dr. David, it was a matter of chance.“When I was a kid in school, the only thing I ever 42 to be was a veterinarian (兽医),” says Dr. David. “I even applied to the veterinary school in college.” But Dr. David soon realized that veterinary work was 43 for him. “I volunteered at a veterinarian’s office to get some experience,” he says. “I was pitiful. I couldn’t breathe. My eyes were swollen shut. I had allergy symptoms.” So Dr. David tried pediatric dentistry and found he loved it.After he became a dentist, Dr. David 44 at Children’s Hospital in Cincinnati, Ohio. While there, he was asked to help with dental work on some of the 45 in the hospital’s research lab. It wasn’t long before he began a dental program for the animals.Word of Dr. David’s work with animals 46 , and soon King’s Island Amusement Park and the Cincinnati Zoo were calling to ask for his 47 .

Each passage is followed by several questions or unfinished statements. For each of them there are 4 choices marked A, B, C and D. Choose the one that fits best according to the information given in the passage.ALooking through a magazine in a waiting room recently, I came across an article with the title “My top five most precious possessions”. It was just a few lines of text with pictures, but it caught my imagination.It’s interesting how inanimate(无生命的) objects can take on such significance and become woven(编织)into a person’s, and sometimes a whole family’s, life history.Anyway, the article had me considering what my most precious possessions are. It was difficult to choose only five, but here are mine:An old cardboard box filled with my children’s baby photos.A yellow pocket-sized birthday book of special things (poems, pictures of flowers and trees, etc) given to me by my dad when I was probably about seven or eight years old.A 21st birthday card from my mum. In it she’s written her congratulations, her love, and her hopes for my future. She died not long after, when I was in my early twenties.A few ancient but very beautiful botany books that were once my great grandmother’s. She was a botanist in a time when it was relatively unusual for women to be qualified in this field and I think she was probably a remarkable and very interesting woman. I’d like to have known her.A brooch(胸针) left to me by my much-loved grandmother. It was given to my great grandmother by my great grandfather on his return from World War I. It is not worth anything in terms of money. However, it not only stands for a link between four generations of women, but it is also a reminder of one young man’s return from World War I.How about you? I’d love to hear what you feel are your most precious possessions.56.What made the writer have the idea of writing the passage?A. Her love for her relatives.B. Her rich imagination about the objects.C. An article in a magazine.D. Some pictures in an article.57. According to the passage, the writer __________.A. lost her mother at the age of 26B. was a mother of several childrenC. got the yellow birthday book at 8D. studied botany well when she was young58. The writer considered her grandmother remarkable and interesting because she __________.A. wrote a large number of botany booksB. left the writer some ancient but beautiful botany booksC. was unusually famous for her achievementsD. could become a botanist in the special time59. How many reasons made the writer think the brooch was one of her most precious possessions?A. oneB. twoC. threeD. four60.In the writer’s opinion, something that is thought to be the most precious should be able to_____.A. represent a person’s and even the whole family’s life historyB. have a great effect on others’ livesC. remind somebody of his or her friendsD. show a person’s love and respect for his or her relativesBWhen my friend put out the idea of homeschooling to her parents, the first reaction they gave was, “You are cutting the child off the world.” Did the child really get cut off or did the child socialize better?The moment we hear of homeschooling, we think the child will have no opportunities to interact with peers. However, in my friend’s opinion, we forget that when attending a regular school, the child is not into socializing all the while. The child is confined to so many other activities. Studies take a major role in a child’s life. The child hardly has the time to interact at school.The child might be meeting and studying along with many peers; however, how many kids interact with all the kids in a class? But in homeschooling system, as my friend mentioned, the kid has all the time and can plan his day accordingly. During the day the child studies just like other school-going kids but with no burden of homework and project work, the child has so much free time in the evening as to effectively interact and play with peers. The quality time the child spends in education is really impressive.Homeschooled kids have the opportunity to socialize more often as they have a lot of time in their hands. They can also make socializing a regular habit. Just as my friend said, her child goes to a neighboring park almost every day and has a set of friends who go there daily. Other children get back home to finish off homework and project work whereas her child who is already through with studies gets the opportunity to spend time with family members.When I heard this, I really felt how lucky the child was. Definitely the child had a better opportunity to socialize when compares with my kids. However, I might not consider homeschooling for my kid, as I am so used to the traditional schooling system and feel regular schooling the safest bet.61. What is the author’s attitude towards his friend’s idea of homeschooling?A. Negative.B. Objective.C. Surprised.D. Indifferent.62. The underlined word can be replaced by _______.A. freeB. restrictedC. devotedD. accustomed63. What do we know about homeschooling children?A. They don’t interact with their peers often.B. They have more spare time to play.C. They have no chance to play with friends.D. They can’t gain enough knowledge.64. According to the author’s friend what is the biggest advantage of homeschooling children?A. They will become braver.B. They can be more popular.C. They can be better at socializing.D. They can study better.65. The author’s purpose in writing the passage is to _________.A. express his views on homeschooling.B. explain what homeschooling is.C. share his ways of teaching his children.D. promote homeschooling.CPeople have been acting like people—in other words, they’ve been making tools, creating ceremonies, and sharing food—for a long time. That’s the conclusion of a recent stu dy from South Africa’s southern coast.There, in a cave lying above the sea, researchers from Arizona State University have found evidence that humans were behaving in surprisingly complex ways as early as 164,000 years ago. Our species, Homo sapiens, appeared an estimated 200,000 years ago.The cave held three important clues about the behavior of these Stone Age people.First, the researchers found the remains of all kinds of shellfish. The people who lived in the cave probably collected these creatures from rocky shores and tide pools and brought them to the cave to eat.The researchers propose the early Africans moved to the South African coast between 195,000 and 130,000 years ago. Around that time, the climate inland turned relatively cold and dry. Therefore, there were fewer plants and animals to eat away from the coast.When these ancient people moved to the coast, they probably experienced a major cultural shift, the researchers suspect. That’s because observations of modern hunter­gatherer soci eties suggest that men are more likely to hunt for big animals when people live inland. On the coast, women play a more important role in providing food by gathering plants and shellfish. As for the second clue, the researchers unearthed 57 pieces of reddish pigment(颜料). The researchers think that the cave habitants used the paint for coloring their bodies or for other ceremonies. Symbolic behavior is aclearly human feature.Finally, the search discovered over 1,800 stone tools, including well-crafted blades(刀片). These blades came in various sizes. The smallest were just less than a half-inch wide. Ancient people may have attached these blades to the end of a stick to make spears or other tools.66. From the first paragraph we know that people could do many things long time ago EXCEPT________.A. make bladesB. create paintingsC. hold ceremoniesD. share food67.The early Africans moved to the South African coast with the main purpose of ________.A. avoiding badly cold and dry weatherB. seeking the cultural developmentC. seeking enough food to live onD. living a newer and better life68.According to the passage, the cave habitants________.A. knew how to use colors for decorationB. made a living largely by hunting animalsC. only could made tools with rough bladesD. could hunt for fish in the sea with ships69.After the early Africans moved to the coast, what probably happened to their culture?A. Women’s role was as important as men’s role in f amilies.B. They were no longer used to living inlands but living on the coast.C. Men’s role was more important than women’s role in earning food.D. Women’s role was more important than men’s role in earning food.70.What is the passage mainly about?A. Ancient cave behavior.B. New evidence of ancient life.C. The history of human beings.D. Human behavior’s development.Part IV Writing (45 marks)Section A (10 marks)Directions: Read the following passage. Complete the diagram/Fill in the numbered blanks by using the information for the passage. Write NO MORE THAN 3 WORDS for each answer.Career tests can prove to be very useful in deciding the choices and interests of high school students. As a part of a career test, an aptitude(资质) test is necessary. It’s a test to judge a candidate’s ability in various basic as well as specialized skills.Students in high school are at an age when they are making their career plans and deciding on which degree they should aim for in order to get their dream job. As for the functions of aptitude tests, they can help those who take them to realize where their aptitude lies and select the recommended careers, according to their skills.There are usually three most common types of aptitude tests.General Aptitude Test Battery: This test helps in understanding which occupation your talents are best suited for. It’s a career test which many advisers make use of even in corporate organizations. This test compares the aptitude of the person taking the test with the established standards of success as noted by companies. It checks your aptitude in various abilities and skills.Strong Interest Inventory: With the duration of only about 25 minutes, this test is also used by many employers to hire potential employees. It can predict talents by comparing your interests in things with people who are employed in specific professions.Myers-Briggs Type Indicator: This test is more of a personality test than an aptitude test but understanding how a person views the world around him and how it affects his decision-making ability can help an adviser predict career talents, making this a test that can be hugely effective.An aptitude test can be helpful, but it just provides you with suggestions that you can use in order to decide on a specific career. It is important though that you keep your interests in mind and not get influenced by the test results alone.Section B (10 marks)Directions: Read the following passage. Answer the questions according to the information given in the passage.M arti Sementelli has been a baseball player since preschool, throwing plastic balls and swinging a tiny wood bat from the time she was 3 years old. She was a solid player at every youth level, and sometimes a star. In 2007, Nike even featured the young Californian in a TV commercial.Despite her experience, Sementelli, now 16, had a hard time finding a high school that would allow her to try out for the boys’ baseball team.Two private schools near her family’s home in North Hollywood said no, and several public schools were not interested in the idea. Finally, she found Burbank High School, where she’s now a sophomore and a member of the JV baseball team.Sementelli’s story is not unique. Across the country, girls devoted to baseball--and with as many seasons of youth ball under their belts as their male teammates--are finding it isn’t easy to stay in the sport when they reach high school.Biology does play a role in the situation: Boys, especially older ones, often have an edge over girls in size and strength, allowing them to throw harder and swing with greater force. But girls say that the toughest battles are not about capabilities, but against the traditional attitude that baseball is for boys.“Most people just are incapable of seeing beyond what’s easy,” says Jennifer Ring, the author of Stolen Bases: Why American Girls Don’t Play Baseball, and a professor at the University of Nevada-Reno. “It is much neater if we say boys play baseball and girls play other sports.”In at least one state, Massachusetts, girls are barred from trying out for boys’ baseball in high schools that also offer softball. Nebraska along with Minnesota dropped their ban last year, and in January, Indiana removed its ban after being charged by the parents of Logan Young, a 15-year-old aspiring catcher and freshman at Bloomington South High School.81.

A—For Each Vocabulary Word You Get Right,We Donate Free Rice through the United Nations World Food Program to Help End World Hunger1word=20grains;5words=100grainsPlay and feed hungry people.How to playClick on the answer that best defines the word.If you get it right,you get a harder word.If wrong,you get an easier word.For each word you get right,we donate20grains of rice to the United Nations World Food Program.WARNING:This game may make you smarter.It may improve your speaking,writing,thinking, grades,job performance...(more)Frequently Asked QuestionsHow does playing the vocabulary game at FreeRice help me?Learning new vocabulary has tremendous benefits.It can help you:★Present your ideas better★Write better papers,emails and business letters★Speak more accurately and influentially★Read faster because you understand better★Get better grades in high school,college and graduate school★Perform better at job interviews and conferences★Be more effective and successful at your job…After you ha ve done FreeRice for a couple of days,you may notice an odd phenomenon. Words that you have never consciously used before will begin to pop into your head while you are speaking or writing.You will feel yourself using and knowing more words.How does the FreeRice vocabulary program work?FreeRice has a custom database(数据库)containing thousands of words at varying degrees of difficulty.There are words proper for people just learning English and words that will challenge the most learned professors.In between are thousands of words for students, business people,doctors,truck drivers…everyone!FreeRice adjusts to your level of vocabulary.It starts by giving you words at different levels of difficulty and then,based on how you do,designs a proper starting level for you.When you get a word wrong,you go to an easier level.When you get three words in a row right,you go to a harder level.There are60levels in all,but it is rare for people to get above level50.1.Playing the vocabulary game at Freerice enables you to do the following EXCEPT______.A.be admitted to a top university.B.perform better in a speech contestC.help the needy people in the worldD.improve your performance at work2.People of different levels of learning can surf FreeRice because_______.A.it offers a large vocabularyB.it is free of charge to play the game.C.it is designed to meet the needs of people in different fieldsD.it adjusts to the player’s level of vocabulary3.We can infer from the passage that the purpose of designing the game is to______.A.supply more rice to feed the hungry people in poor countriesB.promote English learning in non-English speaking countriesbine English learning with helping hungry peopleD.attract more people to learn English to stop hunger4.Where is the passage likely to appear?A.On the website.B.In a farming magazine.C.In a popular newspaper.D.In a document of the UN.BMany people in high school cannot wait to go to college and leave their hometown behind. Questions arise,though,when it comes to all of the decisions involved in choosing a college. One of the first considerations may be finance.State and public colleges are often the least expensive.Often,though,the better colleges are private and more expensive.It is sad when gifted students cannot attend a college of their choice just for financial reasons.Another major factor is location.Whether the college is i n a small town or large city can have a major impact on its activities.A water lover probably will be more comfortable spending four years near an ocean or a lake.Those who cannot tolerate heat will probably be more comfortable at a northern college.Distance from home may also come into consideration.If family is a top priority,that person should stay close to home;on the other hand,if independence is desired,a campus farther from home would be more appropriate.School size also plays a major role in the decision process.If you want to get to know your teachers,a small college is suitable.For those of you who consider yourself a“people person”and want a wide range of activities,a large college is more fitting.Your area of interest is another factor to consider in the decision-making process if you want to get the most from your education.The whole point of college is to learn what is of interest to you.Crucially(至关重要地),one must take into consideration the colleges by which you can realistically be accepted.An Ivy League school for an average student would probably not be a good match.Similarly,an average school for an above-average student would not work well.The college should provide enough of a challenge for the student to work hard. Although there may not be the perfect college out there,there probably will be one that is close.Those who cannot find a suitable college are probably not looking hard enough.5.When it comes to going to college the author thinks.A.financial situation is the first to considerB.students are unwilling to leave their homeC.students will become homesickD.students are eager to attend their ideal university6.What is the main idea of the third paragraph?A.Students can be independent at college.B.A long distance will make students upset.C.The location of the college is a main factor.D The climate must be taken into consideration.7.What does the underlined part“people person”in the passage mean?A.A person of great capacity.B.A very particular person.C.A very sociable person.D.A person of great importance.8.Which is the most important factor when choosing a college?A.The location of a college.B.The examination result.C.School size.D.The coming challenges.CWhy should I teach my children history?That sounds like a stupid question to even ask.But,as I hear different home schooling teachers discuss history,I get the idea that there may be different reasons for teaching history.Let me briefly explain the three good reasons for studying history and two bad reasons for studying history.The major reason I see for studying history is that we can learn from the past.I am convinced that the world would be a much better place if more people understood the successes and failures of the past and the things that made these successes and failures.However, as the unfortunately true statement goes"the one thing we seem to learn from history is that we don't seem to learn from history."Perhaps at least in teaching history,to my children I can do a small part in changing this.The second major reason for studying history is that it is hard to understand the current political clim ate in the absence of an understanding of its historical context.We can not even understand why we are and where we are without history,much less(更不必说)try to figure out where we are going or how we should get where we want to be.I teach my children history,for one more reason.I purchased a set of historical audio (录音机)tapes for our children.My seven-year-old son listened to them over and over.It was my hope that he would become inspired b y the accomplishments of people like the Wright brothers to accomplish things by himself.I think that it is good that we celebrate the accomplishments of people like Martin Luther King Jr.i f,in doing so,young people are called on to stand for the principles that he stood for and accomplish what he accomplished.I also think that by studying people like Adolph Hitler,people can learn to stand against the things that he stood for.9.In Paragraph3,the author shows that history is useful because_______________.A.it makes the current political situation go smoothlyB.it helps us realize the importance of historical eventsC.it helps us understand why things are the way they areD.it helps people accept the present situation where they live10.Some historical figures(人物)are mentioned in the last paragraph to show ______________.A.people can be inspired to do good,while also learning to fight against evilB.people may also learn from bad historical figuresC.more celebrations should be held to honor their achievementsD.today’s people can also achieve what they achieved11.What would be talked about in the following paragraph?A.How to teach history effectively.B.Some negative reasons for studying history.C.How to get more people to study history.D.Some bad historical figures.12.The main purpose of this passage is to____________.A.inspire the parents to teach their children historyB.show the importance of history in politicsC.explain the reasons why children study historyD.introduce the writer's own way of teaching historyDBamboo is one of the nature’s most surprising plants.Many people call this plant a tree,but it is a kind of grass.Like other kinds of grass,a bamboo plant may be cut very low to the ground,but it will grow back very quickly.A Japanese scientist recorded one bamboo plant that grew almost 1.5meters in24hours!Bamboo grows almost everywhere in the world except Europe.There are more than1,000kinds of bamboo that grow around the world on both mountains and plains(平原).Not all bamboo looks the same.Some bamboo plants are very thin.They may only grow to be a few centimeters wide while others may grow to more than30centimeters across.This plant also comes in different colors,from yellow to black to green.Many Asian countries have been using bamboo for hundreds of years.They often use bamboo for building new buildings.As a matter of fact,the cables(绳索)that hold up the hanging bridge across the Min River in Sichuan are made of bamboo.The bridge has been in use for more than1,000years,and is still holding strong.In Africa,engineers are teaching poor farmers how to find water using bamboo.These African countries need cheap ways to find water because they have no money,and their fields often die from no rain and no water.It seems that bamboo is one of the best things they can use.Bamboo pipes and drills(钻)can help to make the poor thirsty fields to be watered.13.How is bamboo like grass?A.It is thin and easy to cut.B.It grows quickly after its cut shortC.It grows everywhe re.D.It is short and green.14.The sentence“while others may grow to more than30centimeters across.”means“Some other bamboo plants may grow to be very_______.”A.shortB.thickC.strongD.tall15.From the text we know______.A.most people call bamboo plant treesB.a bamboo plant may grow4.5meters in three daysC.the bamboo plant changes its colors when it growsD.a bridge held by bamboo cable was built thousands of years ago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。
