Answer the questions on each text by choosing A, B,C or D. Mark your answers on ANSWER SHEET 1.Text 1A former town hall worker made legal history last week when she was awarded 67,000 pounds for stress brought on by her work. The ruling made Beverley Lancaster the first person to get their employer to accept legal responsibility for stress-related personal injury in a British court. It is likely to start a flood of other worker’s claims; Mrs. Lancaster’s union already has 7,000 stress-related cases on its books.The 44-year-old mother of two started a legal case against Birmingham City Council after falling ill while working as a troubleshooter in a neighborhood housing office. Dealing with rude and abusive members of the public pushed her into periods of gloom and she suffered anxiety, Birmingham county court heard. Mrs. Lancaster joined the council at 16, working her way up from junior clerk to senior draughtswoman. Her problems began when she was promoted to housing officer in Sutton Oldfield. "With no continuity, a constant high workload and little clerical support, I found it difficult to switch from one problem or situation to another," she said. "My concentration swung and I suffered sleepless nights. It made me feel like I was in a hole with no key to open the door. I would break down in tears. I was being in paperwork and at times my mind would just go blank."In awarding compensation of 67,491 pounds, assistant recorder Frances Kirkham said she understood the position of troubleshooter was very different from Mrs. Lancaster’s precious job. She rejected claims from the council that Mrs. Lancaster would be able to go back to her former profession, saying she accepted that the possibility of future work would be less capacity.After the hearing Mrs. Lancaster said she was relieved and pleased. She added, "I hope this will act as a warning to employers. Everything I did was right. The council made promises to me and they failed me. I felt isolated, let down, that I was not good enough, not wanted." The payout, the first of its kind to be decided in a county court, covers loss of wages and future loss of earnings.A spokesman for Birmingham City Council said action had been taken by the authority to review its staff and management procedures.46.Mrs. Beverley Lancaster was awarded 67,000 pounds for ______.A.illness caused by her jobB.her successful and good luckC.the courage she showed in courtD.the amount of work she did47.Mrs. Beverley Lancaster took legal action against the city council because ______.A.it refused to award her for her jobB.she had to deal with rude members of the councilC.it was responsible for her problemsD.it denied her any clerical support48.The Lancaster case shows that employees have the right to get compensation if they ______.A.are given work that they are unable to doB.suffer mental injury caused by their workC.are forced to do work that they don’t likeD.feel isolated, let down and extremely anxious49.It can be inferred that ______.A.Mr Lancaster will find a better paid job in the futureB.the job of draughtswoman is very demandingC.the court may hear more stress-related casesD.the job of housing officer causes mental injuries50.If Birmingham City Gouncil plans to move an employee to a new job, it will definitely make sure that ______.A.there is continuity between the two jobsB.no complaints from the employee occurC.the amount of work is reduced for the new jobD.the employee is prepared for any mental problemsText 2Life learning (sometimes called un-schooling or self-directed learning) is one of those concepts that are almost easier to explain by saying what it isn’t, than what it is. And that’s probably because our own schooled backgrounds have convinced usthat learning happens only in a dedicated building on certain days, between certain hours, and managed by a specially trained professional.Within that schooling framework, no matter how hard teachers try and no matter how good their textbooks, many bright students get bored, many slower students struggle and give up or lose their self-respect, and most of them reach the end of the process unprepared to enter into society. They have memorized a certain body of knowledge long enough to rush back the information on tests, but they haven’t really learnt much, at least of the official curriculum.Life learners, on the other hand, know that learning is not difficult, that people learn things quite easily if they’re not compelled and forced, if they see a need to learn something, and if they are trusted and respected enough to learn it on their own timetable, at their own speed, in their own way. They know that learning cannot be produced in us and that we cannot produce it in others—no matter what age and no matter whether we’re at school or at home.Life learning is independent of time, location or the presence of teacher. It does not require mom or dad to teach, or kids to work in workbooks at the kitchen table from 9 to noon from September to June. Life learning is learner-driven. It involves living and learning— in and from the real world. It is about exploring, questioning, experimenting, making messes, taking risks without fear of making mistakes, being laughed at and trying again.Furthermore, life learning is about trusting kids to learn what they need to know and about helping them to learn and grow in their own ways. It is about providing positive experiences that enable children to understand the world and their culture and to interact with it.51.It is implied in the text that it is hard to ______.A.carry life learning thoughB.tell the nature of life learningC.learn without going to schoolD.find a specially trained teacher52.According to the author, the schooling framework often ______.A.produces slow students with poor memoriesB.ignores some parts of the official curriculumC.fails to provide enough knowledge about lifeD.gives little care to the quality of teaching materials53.Life learners recognize that learning will not be difficult if they are ______.A.clear about why to learnB.careful to make a time tableC.able to respect other peopleD.cautious about any mistakes54.According to the author, life learning ______.A.could prevent one from running risksB.could be a road full of trials and errorsC.makes a kid independent of his parentsD.teaches a kid how to avoid being scorned55.Through life learning, children ______.A.will grow without the assistance from parentsB.will learn to communicate with the real worldC.will be driven to learn necessary life knowledgeD.will be isolated from the negative side of societyText 3To find Kim Hyung Gyoon’ s office in Samsung’s R&D complex, just follow the baskets of dirt clothes. No, Kim is not running the company laundry. As chief of Samsung’s Washing & Cleaning Technology Group(WCTG), he’s the man behind a new washing machine that deposits tiny silver particles(small pieces of things) —about 1 / 10,000 the thickness of a human hair— onto clothes to make them germ-and-odor-free without the need of hot water. The device represents the first mass-produced application of this tape of nanotechnology — the science of very small structures —to home appliances. "In summer of 2002, I asked everyone in the office to take off their socks," says Kim. "took one sock from each person and placed it in a regular washing machine; the others were washed in a machine with the Ag+ Nano System. The next day, I asked everyone to check the odor of their socks after a day’s wear. One began produce a strong unpleasant smell, and the other was odorless."Kim says he came up with the idea five years ago while on a business trip to Japan, where he learned of a brand of socks that retained their freshness even after many days of unwashed wear and tear. Tiny sticks of sliver with germ-killing chemicals were woven into the fabric. When he got back to Seoul, Kim applied the principle to washing machines.According to the Korea Testing & Research Industry, Samsung’s device kills 99.9% of germs. Kim says garments stay germ-free for up to a month after being laundered. The Ag+ Nano device went on sale in March 2003 and costs around $1,150; the revolutionary technology is also being used in Samsung’s refrigerators and air conditioners.No wonder: consumers seem to a little sliver in their spin cycles. Since Samsung’s nano-armed products were first launched, they have brought in an estimated $779 million in revenue. Overall, nanotech has been one of science’s fastest-growing fields in recent years, with potential applications in fields as diverse as energy production and toothpaste manufacture. The nanotech market is projected to be worth $1 trillion by 2015.56.Which of the following best describes the nature of Kim Hyung Gyoon’s work?A.Product developmenB.Market investigatioC.Research designinD.Sales promotio57.One advantage of nano-armed washing machines is that ______.A.one wash-load is much larger than beforeB.the clean-up is done with an additional benefitC.cleaning powder is no longer necessaryD.a lot of water could be saved58.In terms of nanotechnology, Kim was the first ______.A.to use it in washing machinesB.to come up with the ideaC.to introduce it to KoreaD.to apply it to socks59.The author believes that the future of nanotechnology will be ______.A.conspicuousB.distinctiveC.foreseeableD.promising60.This text centers on ______.A.the success of an enterpriseB.the application of a technologyC.the market share of Samsung’s WCTGD.the mass-production of a home appliancePart BDirections: Read the following texts in which 5 people expressed their opinions about the concept of "happiness". For questions 61 to 65, match the name of each person (61 to 65) to one of the statements (A to G ) given below. Mark your answers on ANSWER SHEET 1.Heather McCoyEntering a bookstore, one cannot help but notice entire shelves devoted to books boating knowledge of the true path to happiness.Whether this wave of infomercials and books can actually make people happier is the question. Happiness cannot be found by adhering to a narrow set of steps or rules. Finding happiness is not as simple as following a how-to manual, it’s something that every person must find in his or her own way.Gary RussellDoes happiness grow proportionally with wealth? Hardly.Experiences teaches us material satisfaction comes only when one finds himself wealthier than those around him; and, in a like manner, one feels of being lowered when confronting a billionaire, while a worker with a monthly salary of several hundred dollars becomes the envy of the villagers in remote mountainous regions.David NivenTrue happiness is not a result from human action. Results are temporary whereas happiness is everywhere and can neither be created nor destroyed. True happiness is realized by understanding one’s own SELF. With true happiness there is no place for disappointments! True happiness may mean pain and restraint in the beginning but will lead to eternal joy and freedom. To achieve true happiness, we should isolate and remove the negatives.Joshua PartyHappiness is a state of mind. You can be happy in almost any situation. Likewise, you can be unhappy in an equal number of situations. In the end, it’s your decision.If one can control one’s unhappiness, then one must be able to control one’s happiness. As far as I know, the Human Genome Project has not been able to identify a single part of any human chromosome which is responsible for happiness.Laura JohnsonSo what makes me a happy person? Studying to be a journalist because I loved to write, not because it pays a lot of money. Skiing in the winter snow and swimming in the summer sun. Spending time with my close friends from home that like the real me just as much as the old me. Being in a stable family. Reading romance novels and watching bizarre movies. Having a boyfriend who knows more about rock and roll history than I do.Now match the name of each person (61 to 65) to the appropriate statements. Note: there are two extra statements.Statements[A] Happiness lies in persistent pursuit.[B] Happiness is in your own hand.[C] Freedom is positively related to happiness.[D] Happiness is based on comparison.[E] There does not exist a guide to happiness.[F] Happiness is a balance between man and nature.[G] Happiness is all about doing what you want to.Section ⅣWritingDirections:You should write your responses to both Part A and Part B of this section on ANSWER SHEET 2.1.Your TV broke down only one week after it was bought. Write a letter of complaint to the store where your TV set was bought,1)to express what is wrong with your TV set;2)to make your request (change for a new one, or return the broken one ... );3)to urge the store to give an early reply.You should write approximately 100 words. Do not sign your own name at the end of your letter. Use "Wang Lin" instead. You do not need to write your address and the date.2.Bellow is a cartoon about Chinese domestic migration of human resources in recent years. Look at the cartoon and write an essay of about 120 words, make reference to the following points:1)a description of the cartoon;2)the cause and effect of this migration.。

And that’s probably because our own schooled backgrounds have convinced usthat learning happens only in a dedicated building on certain days, between certain hours, and managed by a specially trained professional.Within that schooling framework, no matter how hard teachers try and no matter how good their textbooks, many bright students get bored, many slower students struggle and give up or lose their self-respect, and most of them reach the end of the process unprepared to enter into society. They have memorized a certain body of knowledge long enough to rush back the information on tests, but they haven’t really learnt much, at least of the official curriculum.Life learners, on the other hand, know that learning is not difficult, that people learn things quite easily if they’re not compelled and forced, if they see a need to learn something, and if they are trusted and respected enough to learn it on their own timetable, at their own speed, in their own way. They know that learning cannot be produced in us and that we cannot produce it in others—no matter what age and no matter whether we’re at school or at home.Life learning is independent of time, location or the presence of teacher. It does not require mom or dad to teach, or kids to work in workbooks at the kitchen table from 9 to noon from September to June. Life learning is learner-driven. It involves living and learning— in and from the real world. It is about exploring, questioning, experimenting, making messes, taking risks without fear of making mistakes, being laughed at and trying again.Furthermore, life learning is about trusting kids to learn what they need to know and about helping them to learn and grow in their own ways. It is about providing positive experiences that enable children to understand the world and their culture and to interact with it.51.It is implied in the text that it is hard to ______.A.carry life learning thoughB.tell the nature of life learningC.learn without going to schoolD.find a specially trained teacher52.According to the author, the schooling framework often ______.A.produces slow students with poor memoriesB.ignores some parts of the official curriculumC.fails to provide enough knowledge about lifeD.gives little care to the quality of teaching materials53.Life learners recognize that learning will not be difficult if they are ______.A.clear about why to learnB.careful to make a time tableC.able to respect other peopleD.cautious about any mistakes54.According to the author, life learning ______.A.could prevent one from running risksB.could be a road full of trials and errorsC.makes a kid independent of his parentsD.teaches a kid how to avoid being scorned55.Through life learning, children ______.A.will grow without the assistance from parentsB.will learn to communicate with the real worldC.will be driven to learn necessary life knowledgeD.will be isolated from the negative side of societyText 3To find Kim Hyung Gyoon’ s office in Samsung’s R&D complex, just follow the baskets of dirt clothes. No, Kim is not running the company laundry. As chief of Samsung’s Washing & Cleaning Technology Group(WCTG), he’s the man behind a new washing machine that deposits tiny silver particles(small pieces of things) —about 1 / 10,000 the thickness of a human hair— onto clothes to make them germ-and-odor-free without the need of hot water. The device represents the first mass-produced application of this tape of nanotechnology — the science of very small structures—to home appliances. "In summer of 2002, I asked everyone in the office to take off their socks," says Kim. "took one sock from each person and placed it in a regular washing machine; the others were washed in a machine with the Ag+ Nano System. The next day, I asked everyone to check the odor of their socks after a day’s wear. One began produce a strong unpleasant smell, and the other was odorless."Kim says he came up with the idea five years ago while on a business trip to Japan, where he learned of a brand of socks that retained their freshness even after many days of unwashed wear and tear. Tiny sticks of sliver with germ-killing chemicals were woven into the fabric. When he got back to Seoul, Kim applied the principle to washing machines.According to the Korea Testing & Research Industry, Samsung’s device kills 99.9% of germs. Kim says garments stay germ-free for up to a month after being laundered. The Ag+ Nano device went on sale in March 2003 and costs around $1,150; the revolutionary technology is also being used in Samsung’s refrigerators and air conditioners.No wonder: consumers seem to a little sliver in their spin cycles. Since Samsung’s nano-armed products were first launched, they have brought in an estimated $779 million in revenue. Overall, nanotech has been one of science’s fastest-growing fields in recent years, with potential applications in fields as diverse as energy production and toothpaste manufacture. The nanotech market is projected to be worth $1 trillion by 2015.56.Which of the following best describes the nature of Kim Hyung Gyoon’s work?A.Product developmenB.Market investigatioC.Research designinD.Sales promotio57.One advantage of nano-armed washing machines is that ______.A.one wash-load is much larger than beforeB.the clean-up is done with an additional benefitC.cleaning powder is no longer necessaryD.a lot of water could be saved58.In terms of nanotechnology, Kim was the first ______.A.to use it in washing machinesB.to come up with the ideaC.to introduce it to KoreaD.to apply it to socks59.The author believes that the future of nanotechnology will be ______.A.conspicuousB.distinctiveC.foreseeableD.promising60.This text centers on ______.A.the success of an enterpriseB.the application of a technologyC.the market share of Samsung’s WCTGD.the mass-production of a home appliancePart BDirections: Read the following texts in which 5 people expressed their opinions about the concept of "happiness". For questions 61 to 65, match the name of each person (61 to 65) to one of the statements (A to G ) given below. Mark your answers on ANSWER SHEET 1.Heather McCoyEntering a bookstore, one cannot help but notice entire shelves devoted to books boating knowledge of the true path to happiness.Whether this wave of infomercials and books can actually make people happier is the question. Happiness cannot be found by adhering to a narrow set of steps or rules. Finding happiness is not as simple as following a how-to manual, it’s something that every person must find in his or her own way.Gary RussellDoes happiness grow proportionally with wealth? Hardly.Experiences teaches us material satisfaction comes only when one finds himself wealthier than those around him; and, in a like manner, one feels of being lowered when confronting a billionaire, while a worker with a monthly salary of several hundred dollars becomes the envy of the villagers in remote mountainous regions.David NivenTrue happiness is not a result from human action. Results are temporary whereas happiness is everywhere and can neither be created nor destroyed. True happiness is realized by understanding one’s own SELF. With true happiness there is no place for disappointments! True happiness may mean pain and restraint in the beginning but will lead to eternal joy and freedom. To achieve true happiness, we should isolate and remove the negatives.Joshua PartyHappiness is a state of mind. You can be happy in almost any situation. Likewise, you can be unhappy in an equal number of situations. In the end, it’s your decision.If one can control one’s unhappiness, then one must be able to control one’s happiness. As far as I know, the Human Genome Project has not been able to identify a single part of any human chromosome which is responsible for happiness.Laura JohnsonSo what makes me a happy person? Studying to be a journalist because I loved to write, not because it pays a lot of money. Skiing in the winter snow and swimming in the summer sun. Spending time with my close friends from home that like the real me just as much as the old me. Being in a stable family. Reading romance novels and watching bizarre movies. Having a boyfriend who knows more about rock and roll history than I do.Now match the name of each person (61 to 65) to the appropriate statements. Note: there are two extra statements.Statements[A] Happiness lies in persistent pursuit.[B] Happiness is in your own hand.[C] Freedom is positively related to happiness.[D] Happiness is based on comparison.[E] There does not exist a guide to happiness.[F] Happiness is a balance between man and nature.[G] Happiness is all about doing what you want to.Section ⅣWritingDirections:You should write your responses to both Part A and Part B of this section on ANSWER SHEET 2.1. Your TV broke down only one week after it was bought. Write a letter of complaint to the store where your TV set was bought,1)to express what is wrong with your TV set;2)to make your request (change for a new one, or return the broken one ... );3)to urge the store to give an early reply.You should write approximately 100 words. Do not sign your own name at the end of your letter. Use "Wang Lin" instead. You do not need to write your address and the date.2. Bellow is a cartoon about Chinese domestic migration of human resources in recent years. Look at the cartoon and write an essayof about 120 words, make reference to the following points:1)a description of the cartoon;2)the cause and effect of this migration.。
