Everyone in business has been told that success is all about attracting and retaining (留住) customers. It sounds simple and achievable. But, 1 , words of wisdom are soon forgotten. Once companies have attracted customers they often 2 the second half of the story. In the excitement of beating off the competition, negotiating prices, securing orders, and delivering the product, managers tend to become carried away. They forget what they regard as the boring side of business— 3 that the customer remains a customer.
4 to concentrate on retaining as well as attracting customers costs business huge amounts of money annually. It has been estimated that the average company loses between 10 and 30 per cent of its customers every year. In constantly changing
5 , this is not surprising. What is surprising is the fact that few companies have any idea how many customers they have lost.
Only now are organizations beginning to wake up to those lost opportunities and calculate the 6 implications. Cutting down the number of customers a company loses can make a big 7 in its performance. Research in the US found that a five per cent decrease in the number of defecting (流失的) customers led to 8 increases of between 25 and 85 per cent.
In the US, Domino?s Pizza estimates that a regular customer is worth more than $5,000 over ten years. A customer who receives a poor quality product or service on their first visit and 9 never returns, is losing the company thousands of dollars in 10 profits (more if you consider how many people they are likely to tell about their bad experience).
The logic behind cultivating customer 11 is impossible to deny. “In practice most companies? marketin g effort is focused on getting customers, with little attention paid to 12 them”, says Adrian Payne of Cornfield University? School of Management. “Research suggests that there is a close relationship between retaining customers and making profits. 13 customers tend to buy more, are predictable and usually cost less to service than new customers. Furthermore, they tend to be less price 14 , and may provide free word-of-mouth advertising. Retaining customers also makes it 15 for competitors to enter a market or increase their share of a market.

Police in China have arrested two drivers 16 connection with the death of a toddler 17 was hit and left for dead on a busy street earlier this month in southern China. Police were able to identify the drivers of the two vans 18 examining graphic video of the vehicles 19 (strike) 2-year-old Wang Y ue, who died in the hospital on Friday, about a week after the accident in Foshan, China.

第一节阅读理解(共20小题；每小题2分，满分40分)
A
My newly-rented small apartment was far away from the centre of London and it was becoming essential for me to find a job, so finally I spent a whole morning getting to town and putting my name down to be considered by London Transport for a job on the underground. They were looking for guard s, not drivers. This suited me. I couldn?t drive a car but thought that I could probably guard a train, and perhaps continue to write my poems between stations. The writers Keats and Chekhov had been doctors. T.S. Eliot had worked in a bank and Wallace Stevens for an insurance company. I?d be a subway guard. I could see myself being cheerful, useful, a good man in a crisis. Obviously I?d be overqualified but I was willing to forget about that in return for a steady income and travel privileges — those being particularly welcome to someone living a long way from the city centre.
The next day I sat down, with almost a hundred other candidates, for the intelligence test. I must have done all right because after about half an hour?s wait I was sent into another room for a psychological test. This time there were only about fifty candidates. The interviewer sat at a desk. Candidates were signaled forward to occupy the seat opposite him when the previous occupant had been dismissed, after a greater or shorter time. Obviously the long interviews were the more successful ones. Some of the interviews were as short as five minutes. Mine was the only one that lasted a minute and a half.
I can remember the questions now: “Why did you leave your last job?” “Why did you lea ve your job before that?” “And the one before that?” I can?t recall my answers, except that they were short at first and grew progressively shorter. His closing statement, I thought, revealed a lack of sensitivity which helped to explain why as a psychologist, he had risen no higher than the underground railway. “Y ou?ve failed the psychological test and we are unable to offer you a position.”
Failing to get that job was my low point. Or so I thought, believing that the work was easy. Actually, such jobs — being a postman is another one I still desire — demand exactly the sort of elementary yet responsible awareness that the habitual dreamer is least qualified to give. But I was still far short of full self-understanding. I was also short of cash.
26．The writer applied for the job chiefly because _________.
A．he wanted to work in the centre of London
B．he could no longer afford to live without one
C．he was not interested in any other available job
D．he had received some suitable training
27．The writer thought he was overqualified for the job because _________.
A．he often traveled underground B．he had written many poems
C．he could deal with difficult situations D．he had worked in a company
28．The length of his interview meant that _________.
A．he was not going to be offered the job B．he had not done well in the intelligence test C．he did not like the interviewer at all D．he had little work experience to talk about 29．What does the writer realize now that he did not realize then?
A．How unpleasant ordinary jobs can be. B．How difficult it is to be a poet. C．How unsuitable he was for the job. D．How badly he did in the interview. 30．What?s the writer?s opinion of the psychologist?
A. He was very aggressive.
B. He was unhappy with his job.
C. He was quite inefficient.
D. He was rather unsympathetic.
B
A woman renewing her driver?s license at the County Clerk?s office was asked to state her occupation. She hesitated, uncertain how to classify herself.
“What I mean is,” explained the recorder, “do you have a job, or are you just a …”
“Of course I have a job,” said Emily. “I?m a mother.”
“We don?t list …mother? as an occupation… …housewife? covers it,” said the recorder.
One day I found myself in the same situation. The clerk was obviously a career woman, confident and possessed of a high sounding title．“What is your occupation?” she asked.
The words simply popped out. “I?m a Research Associate in the field of Child Development and Human Relations.”
The clerk paused, ballpoint pen frozen in midair.
I repeated the title slowly, and then I stared with wonder as my statement was written in bold, black ink on the official questionnaire.
“Might I ask,” said the clerk with new interest, “Just what you do in this field?”
Coolly, without any trace of pani c in my voice, I heard myself reply, “I have a continuing program of research (what mother doesn?t）, in the lab and in the field (normally I would have said
indoors and out). Of course, the job is one of the most demanding in the humanities (any mother care to disagree?), and I often work 14 hours a day (24 is more like it). But the job is more challenging than most careers and rewards are more of a satisfaction rather than just money.”
There was an increasing note of respect in the clerk?s voice as she co mpleted the form, stood up, and showed me out.
As I drove into our driveway, buoyed up (依托) by my glamorous new career, I was greeted by my lab assistants---ages 13, 7, and 3.
Upstairs I could hear our new experimental model (a 6 month old baby), in the child-development program, testing out a new vocal pattern．
I felt proud! I had gone on the official records as someone more distinguished and indispensable (不可缺少的) to mankind than “just another mother.”
Motherhood…What a glorious career! Especially when there?s a title on the door.
31. What can we infer from the conversation between the woman and the recorder at the beginning of the passage?
A. The woman felt ashamed to admit what her job was.
B. The recorder was impatient and rude.
C. The author was upset about the situation that mothers faced.
D. Motherhood was not recognized and respected as a job by society.
32. How did the female clerk feel at first when the author told her occupation?
A. curious
B. puzzled
C. indifferent
D. interested
33. How did the author feel when describing her job to the clerk?
A. calm
B. panic-stricken
C. confident
D. cool
34. Why did the woman clerk show more respect for the author?
A. Because the author cared little about rewards.
B. Becaus e she admired the author?s research work in the lab.
C. Because she thought the author did admirable work.
D. Because the writer did something she had little knowledge of.
35. What is the author?s purpose of writing the passage?
A. To show how you describe your job affects your feelings toward it.
B. To argue that motherhood is a worthy career and deserves respect.
C. To show that the author had a grander job than Emily.
D. To show that being a mother is hard and boring work.
C
One reaction to all the concern about tropical deforestation is a blank stare that asks the question, "Since I don't live there, what does it have to do with me?"
The answer is that your way of life, wherever you live in the world, is tied to the tropics in many ways. If you live in a house, wash your hair, eat fruits and vegetables, drink soda, or drive a car, you can be certain that you are affected by the loss of tropical forests.
Biologically, we are losing the richest regions on earth when, each minute, a piece of tropical forest, the size of ten city blocks, disappears. As many as five million species of plants, animals, and insects (40 to 50 percent of all living things) live there, and are being lost faster than they can be found and described. Their loss is immeasurable.
Take rubber for example. For many uses, only natural rubber from trees will do. Synthetics are not good enough. Today over half the world's commercial rubber is produced in Malaysia and
Indonesia, while the Amazon's rubber industry produces much of the world's four million tons. And rubber is an important material in making gloves, balloons, footwear and many sporting goods. Thousands of other tropical plants are valuable for their industrial use.
Many scientists strongly believe that deforestation contributes to the greenhouse effect -- or heating of the earth from increased carbon dioxide in the atmosphere. As we destroy forests, we lose their ability to change carbon dioxide into oxygen.
Carbon dioxide levels could double within the next half-century, warming the earth by as much as 4.5 degrees. The result? A partial melt-down of polar ice caps, raising sea levels as much as 24 feet; even 15 feet could threaten anyone living within 35 miles of the coast. Unbelievable? Maybe. But scientists warn that by the time we realise the severe effects of tropical deforestation, it will be 20 years too late.
Can tropical deforestation affect our everyday lives? Now, you should have got the answer.
36. The underlined word "synthetics" probably means .
A. natural rubber
B. tropical materials
C. man-made material
D. commercial rubber
37. In the last paragraph the author tries to .
A. tell people how to avoid the tropical deforestation
B. persuade people to buy something synthetic
C. show us how important it is to protect the tropical forests
D. let people realise the effect of tropical deforestation
38. According to the passage, which of the following is NOT true?
A. The forests are losing their function in turning carbon dioxide into oxygen.
B. Many of our daily uses are related to the tropical forests.
C. Tropical plants can be used to make industrial products.
D. High carbon dioxide levels will make the earth warmer.
39. The author's attitude towards the tropical deforestation is .
A. puzzling
B. cold
C. supporting
D. opposed
40. Which of the following might be the best title for the passage?
A. Tropical Forests
B. the value of Tropical Forests
C. Tropical Forests and Our Life
D. The Greenhouse Effects D
Nothing succeeds like confidence. When you are truly confident, it radiates from you like sunlight, and attracts success to you like a magnet（磁铁）. Besides, those who are self-confident can in turn inspire confidence in others: their audience, their peers, their bosses, their customers, and their friends. And gaining the confidence of others is one of the key ways in which a self-confident person finds success.
So how can we build a sense of self-confidence and prepare ourselves on the way to success?
First, do what you believe to be right, even if others mock or criticize you for it. Believe in yourself and believe that you can do it under any circumstances, because if you believe you can, then you really will. The belief keeps you searching for answers, which means that pretty soon you will get them.
Second, govern your behavior based on what other people think. What?s more important, be willing to take risks and go the extra miles to achieve better results, in which case mistakes cannot be avoided. Don?t hesitate to admit your mistakes, and learn from them. Next, work hard to settle the problems in order to cover up your mistakes before anyone notices. Building self-confidence is readily achievable, as long as you have the focus and determination to carry things through. And what?s even better is that the things you?ll do to build self-confidence will also build success ----after all, your confidence will come from real, solid achievement. No one can take this away from you!
As you sow, sow will reap. With your perseverance and improvement, you are getting closer to success. At this stage, wait for others to congratulate you on your accomplishments a nd compliments graciously. “Thanks, I really worked hard on that prospect. I?m pleased you recognize my efforts.” The congratulations and compliments from others will promote you to gain further success.
Self-confidence is extremely important in almost every aspect of our lives, and it is no wonder that so many people struggle to find it. Self-confidence really can be learned and built on. Besides, whether you?re working on your own self-confidence or building the confidence of people around you, it?s well worth the effort!
41. Those who are truly confident _________.
A. succeed without effort and hard work
B. encourage people around to become confident
C. appear more attractive and thus become successful
D. gain the confidence of others and feel successful
42. The underlined word “mock” (Para.3 ) is closest in meaning to ________.
A. praise
B. imitate
C. punish
D. laugh at
43. When others congratulate us on our achievements, we are supposed to ________.
A. praise them in return
B. gain further improvement
C. politely accept the compliments
D. expect them to congratulate you again
44. Which of the following proverbs best goes with Paragraph 4?
A. Look before your leap.
B. It is no use crying over spilt milk.
C. Genius is 1% inspiration and 99% perspiration.
D. Learn from past mistakes and avoid future ones.
45. The purpose of the text is to ________________.
A. tell people how to become successful
B. convince people to do what they believe to be right
C. encourage people to build confidence and achieve success
D. criticize people who lack confidence and thus fail in their career

阅读下面的短文，然后按照要求写一篇150词左右的英语短文。
We nowadays live in a global village, and many difficulties will arise if we can't express ourselves fluently in English.
In spite of my awareness of its importance, I seldom find chances to practice and improve my oral English. So, I am still very weak with regard to this respect. One reason is that my pronunciation and intonation aren't good enough. The other is that I am so shy that I am always too nervous to find the exact words to express my ideas and feelings. As a result the best way for me to do is to remain silent when others are practicing and making great progress in their oral English every day.
Now I am attaching much more importance to oral English and I have made up my mind to seize every opportunity to practice. I begin to participate actively in all kinds of English activities, such as going to “English Corners”，talking in English with my classmates and with native speakers. “Nothing is difficult in the world if you really put your heart to it.” as the Chinese saying goes. If I can build up my confidence, if I am not afraid of losing face any more, if I really work hard on it, I am sure my oral English will be excellent someday.

Desires Motivate My Oral English Practice
Living in a “global village”，the writer finds it important to practize oral English, and he has paid more attention to it and is determined to get more chances to practize it.
I had such an experience of oral English practice. Y ears ago, I thought that spoken English was of no use, and I cared little about oral English. After I have known something about Oral English Test in Guangdong College Entrance Examination, I have suddenly daydreamed of being an English major in a famous university. And I have been more diligent. I practize my oral English every morning and evening crazily.
Desires motivate my oral English practice. I realize that hard work creates miracles. All in all, I do hope I will be successful in my Oral English Test in Guangdong College Entrance Examination in March, and I will make my dream come true in the end.

2019年佛山一中自主招生语文试题。 老圣人 赵长春 （1）袁店河有个说法：人读书多了，读得出不来了，就叫“圣人”。这个说法有点讽刺和嘲弄。 （2）老圣人也被称作“圣人”，当年，他被唤作“圣人”，原因不得而知。现在老了就加了个定语，“老圣人”。 （3）老圣人做的事情有些不同于他人。就拿春分这—天来说，他要把村里的小孩子们召集起来，在村中老槐树下的大碾盘上，立蛋。（4）立蛋，就是春分这一天，将鸡蛋立起来。老圣人先示范，轻手撮一鸡蛋，竖在平展的碾盘上，屏息，慢慢松开，鸡蛋就立起来了！然后，他给孩子们分鸡蛋，一人两枚，围绕碾盘，看谁先立起来，发奖。 （5）这个时候，是村子里春节过后的又一次小热闹。不过，大人们不多，年轻人更少，这时候，老圣人看着孩子们，一脸的笑。 （6）人们说:“这有啥意思？自己买鸡蛋，再买些铅笔、写字本文具盒……”老圣人说：“这很有意思。就拿春分立蛋来说，是老祖宗们四千多年前就玩的游戏，一辈辈、一袋袋，传到现在了，会玩的人少了，人家外国反而玩疯……”老圣人说：“一年之计在于春，让孩子们立鸡蛋，心静一下，比玩游戏好。” （7）说话间，已经有好几个孩子将鸡蛋立起来了。孩子们很开心地围拢着老圣人，听他讲春分，讲节气，讲碾盘的故事。 （8）碾盘也有故事，碾盘很老了，村里人用了好多年，如同村口的老井。现在，条件好了，人们不用碾盘了，包括石磙，还有老井。老井早就被填埋了，一些石磨、石磙，还有马槽，莫名其妙地消失了。后来，人们才知道，被人偷跑了，卖到城里了……老圣人就操心老槐树下的大碾盘。有个夜晚，老圣人突然喊了起来，就在老槐树下。原来，那些人又来偷了！ （9）老圣人说，每个人都有故事，每个村子都有历史，每一家都是传奇。这老碾盘，每家的祖辈都吃过它碾出的面、小米、苞谷……他说的故事，有个后来上了大学的孩子写了出来，写进了他的书里。老
