Everyone in business has been told that success is all about attracting and retaining(留住) customers. It sounds simple and achievable. But, 41 , words of wisdom are soon forgotten. Once companies have attracted customers they often 42 the second half of the story. In the excitement of beating off the competition, negotiating prices, securing orders, and delivering the product, managers 43 become carried away. They forget what they regard as the boring side of business--- 44 that the customer remains a customer.
45 to concentrate on retaining as well as attracting customers costs business huge amounts of money annually. It has been estimated that the 46 company loses between 10 and 30 percent of its customers every year. In constantly changing 47 , 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 these lost opportunities and calculate the 48 implications. 49 the number of customers a company loses can make a big 50 in its performance. Research in the US found that a five percent decrease in the number of defecting(流失的) customers led to 51 increases of between 25 and 85 percent.
In the US, Domino’s Pizza estimates that a regular customer is 52 more than five thousand dollars over ten years. A customer who receives a poor quality product or 53 on their first visit and 54 never returns, is losing the company thousands of dollars in 55 profits (more if you consider how many people they are likely to tell about their bad experience).
The logic behind cultivating customer 56 is impossible to deny. “In practice most companies’ marketing effort is focused on getting customers, with little attention paid to 57 them”, says Adrian Payne of Cornfield University’s School of Management. “Research suggests that there is a close relationship between retaining customers and making profits. 58 customers tend to buy more, are predictable and usually cost less to service than new customers. Furthermore, they tend to be less price 59 , and may provide free word-of-mouth advertising. Retaining customers also makes it 60 for competitors to enter a market or increase their share of a market.”

Come prepared: When you arrive at a race, your bike should be in race-ready condition.
Chain Management: Chain damage is still the number one problem with mountain bikes. Keeping your chain clean and well-oiled will help, as will frequent chain replacement. Periodic inspection of your chain for wear, stretch and damage may save you a long walk home.
Packing Tape: This can be used for rims trips, boots for fractured tires and a dozen more makeshift repairs. If you've flown to the race, it also saves you from having to borrow tape to close up your bike box for the flight home. Other musts: safety pins and plastic zip ties.
Pre-race: Visual inspections before any serious off-road ride, carefully examine the area where the tire hooks onto the rim and remove any foreign objects which could cause premature（比预期早的）tire wear.
Tire Pressure: Check tire pressure before race start. The recommended pressure is noted on the tire sidewall, usually 40 lbs., many racers run 50 lbs., or more for less rolling resistance.
Be Self-Contained: Make sure you are self-contained. Bring your own drinking water, food and first aid kit. Also have tools, spare parts, tubes, quick fills and a chain tool. Never suppose you can just borrow these items from a friend.
Post-race Visual Inspections: Inspect your bike after completing each event, especially before competing in a downhill event. Re-inspect before packing your bike for the trip home.

A United Nations report says the number of people in the world is expected to reach 6500 million this July. By the middle of the century, the population could reach more than 9000 million. That would be an increase of 40﹪.
These numbers are fresh estimates for a report on world population change from 1950 to 2050. Hania Zlotnik is director of the U.N. Population Division. She says the world has added nearly 500 million people in the last six years.
But, in her words, "the good news is that new estimates show that it will take a little longer" to add the next 500 million. Mizz Zlotnik says this will probably happen by 2013.
The U.N. report says most population growth by 2050 will take place in less developed countries. Their population is expected to increase from 5000 million today to almost 8000 million. The population of more developed nations is expected to stay about the same, at just over 1000 million.
The report says nine countries will be responsible for about half the world population increase by 2050. These include Bangladesh, China, the Democratic Republic of Congo, Ethiopia and India. The others are Nigeria, Pakistan, Uganda and the United States.
Twelve countries are expected to have populations at least three times the size now. These include Afghanistan, Burkina Faso, Burundi, Chad, Congo and the Democratic Republic of Congo, and East Timor. The others are Guinea-Bissau, Liberia, Mali, Niger and Uganda.
The report says birth rates remain low in forty-four developed countries.
Today, worldwide, there is an average of two-point-six children per woman. This number is expected to fall to just over two children per woman in 2050. But U.N. population experts note that they cannot be sure which way birth rates will go in the future.
The U.N. report also notes that AIDS has increased death rates and slowed population growth in sixty countries. The area most affected by the disease is Southern Africa.
There, how long people live has fallen from an average of sixty-two years in 1995 to forty-eight now. Researchers believe life expectancy will fall to forty-three years by 2015, then begin a slow recovery.
67. Which of the following statements is true?
A. The population growth will slow down in the next few years.
B. Most population growth will take place in developed countries.
C. There is an average of 2.6 children per woman in developed countries.
D. The area most affected by AIDS is Uganda.
68. Which one is the best title of this passage?
A. AIDS slowed population growth.
B. Most population growth will take place in less developed countries.
C. Population growth and death rate.
D. UN world population report.
69．The author believes that the population growth results from_______
A. The birth rate in developed countries is too high.
B. The birth rate in developing countries is too high.
C. AIDS hit only a few countries.
D. A decrease in death rate.
70. Which of the following best describe the author’s attitude towards the rapid population growth?
A. sympathetic B. happy C. optimistic D. critical

In a great many cities, hundreds of people ride bikes to work every day. In New York, some bike riders have even formed a group called Bike for a Better City. They declare that if more people rode bikes to work, there would be fewer automobiles in the downtown part of the city and so less dirty air from car engines．
For several years, this group had been trying to get the city government to help bike riders． For example, they want the city to draw special lanes(车道) for bikes on some of the main streets, because when bike riders must use the same lanes as cars there are accidents. Bike for a Better City feels that if there were special lanes, more people would use bikes．
But no bike lanes have been drawn. Not everyone thinks it is a good idea—they say it will slow traffic. Some store owners on the main streets don’t like the idea—they say that if there is less traffic, they will have less business．
The city government has not yet decided what to do． It wants to keep everyone happy. On weekends, Central Park—the largest place open ground in New York— is closed to cars, and the roads may be used by bikes only．
