He spent all his free time in one of his four glass-houses and grew flowers of every color, with long and difficult names, for competitions (比赛). He tried to grow a rose of a new color to win the silver cup (银杯) for the Rose of the Year.Mr. Flowers’ glass-houses were very near to a middle school. Boys of around thirteen of age were often tempted (引诱) to throw a stone or two at one of Mr. Flowers’ glass-houses. So Mr. Flowers did his best to be in or near his glass-houses at the beginning and end of the school day.But it was not always possible to be on watch at those times. Mr. Flowers had tried in many ways to protect his glass, but nothing that he had done had been useful. He had been to school to report to the headmaster; but this had not done any good. Hehad tried to drive away the boys that threw stones into his garden; but the boys could run faster than he could, and they laughed at him from far away. He had even picked up all the stones that he could find around his garden, so that the boys would have nothing to throw; but they soon found others.At last Mr. Flowers had a good idea. He put up a large notice (布告) made of good, strong wood, some meters away from the glass-houses. On it he had written the words: DO NOT THROW STONES AT THIS NOTICE. After this, Mr. Flowers had no further trouble; the boys were much more tempted to throw stones at the notice than at the glass-houses.56. It was Mr. Flowers’ hope to ________.A. build glass-houses in his free timeB. grow the Rose of the Year in a silver cupC. win a silver cup for growing a rose of a new colorD. grow a rose with the longest name57. Boys were often tempted to ________.A. throw stones at Mr. Flowers’ glass-houseB. throw stones at Mr. Flowers from their schoolC. be in or near by Mr. Flowers’ glass-housesD. play with Mr. Flowers near his glass-houses58. Mr. Flowers stayed in or near by his glass-houses _______.A. at times when school-boys were walking near themB. all the school day when there were no boys aboutC. where he could not be seen by the boys passingD. in his free time at the beginning and end of the school day59. Mr. Flowers had tried to ______ to protect his glass.A. be on watch in his free timeB. ask the headmaster for helpC. pick up all the stones around his gardenD. do all the above60. Mr. Flowers’ good idea was to ______.A. write some words on the glassB. put up a large notice to cover his glass-housesC. give the boys something else to throw stones atD. send for policemenBIn a small village in England about 150 years ago, a mail coach (邮车) was standing on the street. Around the coach many people were talking to one another about it.Mail coach did not come to that village so often in those days. People had to pay a lot of money to get a letter. The person who sent the letter did not have to pay. The person who got the letter had to pay the postage (邮资).“Here’s a letter for Miss Alice Brown,” said the mailman. Everyone turned to a girl of about eighteen who was standing by the coach. “I’m Alice Brown,” she said in a low voice. The mailman gave her the letter.Alice looked at the envelope(信封)for a minute, and then handed it back to the mailman.“I’m sorry I can’t take it,” she said. “I don’t have enough money to pay thepostage.”The people standing around were very sorry for the girl. They were silent for a while. Then a gentleman came up to the mailman and paid the postage for Alice’s letter.When the gentleman gave her the letter, she said with a smile, “Oh, thank you very much, sir. This letter is from the young man I’m going to marry. His name is Tom. He went to London to look for work. He has to get enough money for our marriage (结婚). I’ve waited a long time for this letter, but now don’t need it. I don’t have to open the envelope b ecause there is nothing inside.”“Really?” the gentleman said in surprise. “How do you know that?” “He told me that he would put some signs on the envelope. Look, sir, this cross in the corner means that he is well, and this circle means he has found wor k. That’s very good news.”The gentleman was Sir Rowland Hill. He did not forget Alice and her letter.“The postage to be paid by the receiver has to be changed,” he said to himself. He thought and thought for many years. At last he had a good plan.“The postage has to be much lower,” he said. “What about a penny (便士) for a letter? And the person who sends the letter pays the postage. He has to buy a stamp and put it on the envelope.”“A good idea!” people said when they heard of his plan.The Government decided to adopt (采纳) the plan. The first postage stamp was put out in 1840. It was called the “Penny Black”. It had a picture of the Queen on it.61.The first postage stamp was made ________.A. in EnglandB. in AmericaC. by AliceD. in 191062.The girl handed the letter back to the mailman because ______.A. she did not know whose letter it wasB. the letter had already told her what she wanted to knowC. she could not pay the postageD. the gentleman promised to pay the postage for her63.When the girl returned the letter to the mailman _____.A. the people around her felt sorry for herB. the people thought that the girl was too poorC. none of them wanted to pay the postage for herD. the people was angry with the girl64.Alice knew how Tom was getting from the signs on the envelope because ______.A.

Buses pass front door. Phone 3322108Mr. Brown wants to live near his workplace. Mrs. Brown wants a house with four bedrooms. The Browns’ children don't care what t he house is like as long as the garden is big enough. Ann, their daughter has always wanted to work in a restaurant. She thinks it is an exciting place. It's hard work but she isn’t lazy. You have to work on Saturdays and Sundays, but you get other days of f. It’s not very well paid. But who cares about money?Tom is a middle school student. He is twelve years old. He stops school at half past three,so he has plenty of time to finish his homework.Jack, Mr. Brown's brother, is looking for a room to rent. He doesn't care what color the walls are or how old the furniture is. He is getting ready for his drawing. So the house must be quiet.66.Why didn't the Browns buy the house in Advertisement One?A.

Assistants can have the meals in the restaurant without paying money.C. Customers(顾客)can have the meals freely.D. Assistants need to pay for their meals.The law says that women should have the chance of doing the same jobs as men and earn the same as them.The reality is very different. Women lose because, 25 years after the Equal Pay Act, many of them still get paid less than men.They lose because they do lower-paid jobs which men just won’t consider. And they lose they are the ones who interrupt a career to have children.All this is reported in an independent study ordered by the Government’s women’s unite.The biggest proble m isn’t equal pay in work places such as factories. It is a sort of work women do.Make a list of low-paid of jobs_ then consider who does them.Try nurses, secretaries, cleaner, clerks, teachers in primary schools, dinner ladies, and child care helpers. Not a lot of men among that group, are there?Yet some of those jobs are really important. Surely no one would deny that about nurses and teachers, for a start.So why do we reward the people who do them so poorly? There can be only one answer--- because they are women.This is not going to be put right overnight. But the Government, which employs a lot of them,, and other bosses have to make a start.It is disgraceful(可耻的) that we have gone into the 21st Century still treating women like second-class citizens.71. Women should have the chance of doing the same jobs and be paid equally as men .A. after 25 yearsB. according to the lawC. as a result of the Equal Pay ActD. because women are as strong as men72. We can learn from the text what the problem really matters is ____.A. that the women interrupt a career to have childrenB. what sort of work women doC. because they are womenD. what an unfair pay women get in workplaces.73. Which of the followi ng best describes the writer’s idea?A. Women should get equal pay for equal work to that of men.B. Women should strengthen加强themselves.C.

When the writer says “This is not going to be put right overnight”, he means ____.A. we must solve the problem very quickly.B. there is not completely fair thing all over the world.C. we need a long time to change the unfair reality.D. the problem that women lose will be solved soon.75. Which do you think would be the best title for this passage?A. Work to give women a fair pay deal.B. Time to change the situation.C. Equal work, equal pay.D. Should women be treated like second-class citizens?。

Each statement contains information given in one of the paragraphs. Identify the paragraph from which the information is derived. Each paragraph is marked with a letter.(5* 2 points=10 points)Understanding Chinese ParentsA).What Chinese parents understand is that nothing is fun until you’re good at it. To get good at anything you have to work, and children on their own never want to work, which is why it is crucial to override(不顾) their preferences. This often requires a strong will on the part of theparents because the child will resist; things are always hardest at the beginning, which is where Western parents tend to give up. But if done properly, the Chinese strategy produces a virtuous circle(良性循环). Practice, practice, practice is crucial for excellence; rote repetition(死记硬背) is not welcome in America. Once a child starts to excel at something —whether it’s math, piano or ballet —he or she gets praise, admiration and satisfaction. This builds confidence and makes the once not-fun activity fun. This in turn makes it easier for the parent to get the child to work even more.B).I think there are three big differences between the Chinese and Western parents.C).First, I’ve noticed that Western parents are extremely anxious about their children’s self-esteem. They worry about how their children will feel if they fail at something, and they constantly try to reassure their children about how good they are despite a mediocre(平庸的)performance on a test. In other words, Western parents are concerned about their children’s feelings. Chinese parents aren’t. They assume strength, not fragility, and as a result they behave very differently.D).Second, Chinese parents believe that their kids owe them everything. The reason for this is a little unclear, but it’s probably a combination of Confucian filial piety(孝顺)and the fact that the parents have sacrificed and done so much for their children. Anyway, the understanding is that Chinese children must spend their lives repaying their parents by obeying them and making them proud.E).Third, Chinese parents believe that they know what is best for their children and therefore do not respect all of their children’s own desires and preferences. That’s why Chinese daughters can’t have boyfriends in high school and why Chinese kids often can’t go camping.F).D on’t get me wrong: It’s not that Chinese parents don’t care about their children. Just the opposite. They would give up anything for their children.G).Western parents try to respect their children’s individuality, encouraging them to pursue their true passions, supporting their choices, and providing a favorable environment. By contrast, the Chinese believe that the best way to protect their children is by preparing them for the future, letting them see what they’re capable of, and arming them with skills, work habits and inner confidence that no one can ever take away.()31. Western parents try to show respect for their children’s choices, and provide them with an advantageous environment.()32. Chinese parents do n’t respect all of their children’s own desires and preferences because they believe that they know what is best for their children.()33. It is believed that Chinese children must take their lives to pay back their parents by complying with them and becoming their pride.()34. It’s important to reject the children’s preferences because they themselves refuse to work hard.()35. Western parents continuously try to remove their children’s doubts by saying they are very good, even though they have showed a low quality on a test.Section CDirections: There are 2 passages in this section. Each passage is followed by five questions. For each of them there are four choices marked A, B, C and D. You should decide on the best choice among the options provided. (10*2 points= 20 points) Passage 1If you live in a city in North America or Europe, you have probably never thought much about water. Whenever you need some, you turn on the tap(⽔龙头) and there it is. Millions of people in other parts of the world are not so lucky. They have trouble getting enough clean water for their basic needs. This situation may soon become common all around the world. Scientist believes that the lack of clean water may be one of the biggest issues in the twenty-first century.The reasons for this are clear. On the one hand, people are using more water than ever. Over the last fifty years, the population of the world has more than doubled. So has the demand for water. On the other hand, supplies of clean water are disappearing. Many sources of surface water are too polluted and unhealthy for use as drinking water. This has forced more and more people to drill wells so they can get clear water from underground.If the world does not want to go thirsty in the near future, scientists say, further pollution must be prevented. Around the world, government must make real changes in industry, agriculture, and waste disposal.36. According to the first paragraph, millions of people in the word have trouble in getting_______________A) Enough facilities to supply drinking water.B) Enough food for the increasing population.C) Enough clean water for their basic needs.D) Enough living space in the world.37. What has happened in the actual situation of water in the last 50 years?A) Reasons of using too much water have been found.B) Sources of surface water have become less polluted.C) Enough clean water can be obtained from underground.D) The demand for water has more than doubled.38. It is implied from the passage that underground water is now______________A) Still healthy for useB) Also seriously pollutedC) The only source of clean waterD) The only way to save the world from going thirsty39. What should be done to prevent the world from going thirsty in the future according to the writer?A) To develop more water industries.B) To cut down the world population.C) To stop the pollution of water.D) To make changes in the world economy.40. Which of the following statements is TRUE according to the passage?A) European people are worrying about clean drinking water.B) Scientists think lack of clean water is a serious problem in the future.C) People prefer drinking underground water rather than surface water.D) Disposal of wastes has nothing to do with water pollution.Passage 2High-quality customer service is preached (宣扬) by many, but actually keeping customers happy is easier said than done. Shoppers seldom complain to the manager or owner of a retail store, but instead will warn their friends, relatives, co-workers, strangers—and anyone who will listen.Store managers are often the last to hear complaints, and often find out only when their regular customers decide to frequent their competitors, according to a study jointly conducted by Verde Group and Wharton School.“Storytelling hurts retailers and entertains consumers,”said Paula Courtney, President of the Verde Group. “The store loses the customer, but the shopper must also find a replacement.”On average, every unhappy customer will complain to at least four others, and will no longer visit the specific store. For every dissatisfied customer, a store will lose up to three more due to negative review. The resulting “snowball effect”can be disastrous to retailers.According to the research, shoppers who purchased clothing faced the most problems. Ranked second and third were grocery and electronics customers.The most common complaints include filled parking lots, cluttered (塞满了的) shelves, overloaded racks, out-of-stock goods, long check-out lines, and rude salespeople.During peak shopping hours, some retailers solved parking problems by getting moonlighting (业余兼职的) local police to work as parking assistants. Some hired flag wavers to direct customers to empty parking spaces. This guidance eliminated the need for customers to circle the parking lot endlessly, and avoided conflict between those eyeing the same parking space.Retailers can relieve the headaches by redesigning store layouts, pre-stocking sales goods, hiring speedy and experienced cashiers, and having sales representatives on hand to answer questions.Most importantly, salespeople should be diplomatic and polite with angry customers.“Retailers who’re responsive and friendly are more likely to smooth over issues than those who aren’t so friendly,”said Professor Stephen Hoch. “Maybe something as simple as a greeter at the store entrance would help.”Customers can also improve future shopping experiences by filing complaints to the retailer, instead of complaining to the rest of the world. Retailers are hard-pressed to improve when they have no idea what is wrong.41. Why are store managers often the last to hear complaints?A) Most customers won’t bother to complain even if they have had unhappy experiences.B) Customers would rather tell their unhappy experiences to people around them.C) Few customers believe the service will be improved.D) Customers have no easy access to store managers.42. What does Paula Courtney imply by saying “…the shopper must also find a replacement”(Line 2, Para. 4)A) New customers are bound to replace old ones.B) It is not likely the shopper can find the same products in other stores.C) Most stores provide the same kind of service.D) Not complaining to manager causes the shopper some trouble too.43. Shop owners often hire moonlighting police as parking assistants so that shoppers________.A) can stay longer browsing in the storeB) won’t have trouble parking their carsC) won’t have any worries about securityD) can find their cars easily after shopping44. What contributes most to smoothing over issues with customers?A) Manners of the salespeople.B) Hiring of efficient employeesC) Huge supply of goods for sale.D) Design of store layout.45. To achieve better shopping experiences, customers are advised to ________.A) exert pressure on stores to improve their serviceB) settle their conflicts with stores in a diplomatic wayC) voice their dissatisfaction to store managers directlyD) shop around and make comparisons between storesSection DDirections: After reading it, you are required to find the items equivalent to (等同于) those given in Chinese in the table below. Then you should put the corresponding letter in the brackets, numbered 46 through 50 (5*2 points =10 points):A – Unemployment benefitB -- Household electronic applianceC -- Certificate of originD -- Local area networkE -- Industrial heartlandF -- Consumption patternG -- Food additive H -- A repeat orderI -- Annual production J -- Multinational corporationK -- Mass media L -- Rare earthM –Delivery fee N- Service managerO -- Abstract painting P -- Plastic surgeryExamples;(L) 稀⼟(N) 服务经理46.( ) ⼯业中⼼区域( ) 局域⽹47.( ) 跨国公司( ) 失业救济⾦48.( ) 再次订购( ) 整形⼿术49.( ) 家⽤电器( ) 运费50.( ) ⾷品添加剂( ) ⼤众媒体Part III: IQ Test(5%)Directions: This part, composed of five questions, is to test your IQ ability.You are required to either choose the best answer from the given options or offer your own answer according to the questions.

参考答案
三、解答题
17. (1)由⎩
⎨⎧0303>->+x x ,得-3<x <3, ∴ 函数f (x )的定义域为(-3,3).
(2)函数f (x )是偶函数,理由如下:
由(1)知,函数f (x )的定义域关于原点对称,
且f (-x )=lg (3-x )+lg (3+x )=f (x ),
∴ 函数f (x )为偶函数.
18. 解:21tan 31,2tan k k αα⋅=-=∴=±,而παπ2

得tan 1α=,则sin cos 2
αα==-
,cos sin αα∴+=。

19. .解:(1)f (x )的最小正周期为π.
x 0=7π6,y 0=3. (2)因为x ∈⎣⎡⎦⎤-π2,-π12,所以2x +π6∈⎣⎡⎦
⎤-5π6,0. 于是,当2x +π6
=0, 即x =-π12
时,f (x )取得最大值0; 当2x +π6=-π2
, 即x =-π3
时,f (x )取得最小值-3. 20.解:(1)甲组研发新产品的成绩为
1,1,1,0,0,1,1,1,0,1,0,1,1,0,1,
其平均数为x 甲=1015=23
, 方差为s 2甲=115⎣⎡⎦⎤⎝⎛⎭⎫1-232×10+⎝⎛⎭⎫0-232×5=29

, 方差为s 2乙=115⎣⎡⎦⎤⎝⎛⎭⎫1-352×9+⎝⎛⎭⎫0-352×6=625
.
因为x 甲>x 乙,s 2甲<s 2乙,所以甲组的研发水平优于乙组.
(2)记E ={恰有一组研发成功}.
在所抽得的15个结果中,恰有一组研发成功的结果是(a ,b ),(a ,b ),(a ,b ),(a ,b ),(a ,b ),(a ,
b ),(a ,b ),
共7个,故事件E 发生的频率为715
. 将频率视为概率,即得所求概率为P (E )=715
. 21、解:令cos ,[1,1]x t t =∈-,则222(21)y t at a =--+,对称轴2a t =
, 当12a <-,即2a <-时,[1,1]-是函数y 的递增区间,min 112
y =≠; 当12
a >,即2a >时,[1,1]-是函数y 的递减区间,min 141,2y a =-+= 得18
a =,与2a >矛盾; 当112a -≤≤,即22a -≤≤时,22min 121,43022
a y a a a =---=++= 得1,a =-或3a =-,1a ∴=-,此时max 415y a =-+=。

22. (1)由f (x )=ax 2+1bx +c
是奇函数, 得f (-x )=-f (x )对定义域内x 恒成立,则
a (-x )2+1
b (-x )+
c =-ax 2+1bx +c
⇒-bx +c =-(bx +c )对定义域内x 恒成立,即c =0. 又⎩⎪⎨⎪⎧ f (1)=2f (2)<3⇒⎩⎨⎧ a +1b =2 ①4a +12b <3 ②由①得a =2b -1代入②得2b -32b <0⇒0<b <32
,又a ,b ,c 是整数,得b =a =1.
(2)由(1)知,f (x )=x 2+1x =x +1x
, 当x <0,f (x )在(-∞,-1]上单调递增, f (x )在[-1,0)上单调递减.。
