Man: Well, I was thirty and settled at work, but then I came across a report predicting annual internet growth at 2,300%. The figure was like an alarm clock ringing in my head. I started to think about the regrets I might have at eighty. I realised I probably wouldn't even remember the things that seemed important in my thirties (like getting my end-of-year pay bonus. But I'd definitely tell myself I'd been a fool to ignore the internet. Woman: How did you go about choosing a product？ Man: Well, I drew up a list of twenty products, from clothes to gardening tools, and from that I got a shortlist of five, and then I assessed them. I thought about market growth in different countries and I also did some research into suppliers. But there were other important factors as well. I wanted a product that didn't retail for too high a figure. I thought that since many people would be buying from the internet for the first time, they might be afraid to take a risk with large amounts of money. Woman: And what made you decide on books？ Man: Well, basically, I found out that books had an eighty-two billion dollar market world-wide. There's also a high demand for CDs - a product I nearly went for - but with books there's a much wider choice. There're 3 million items in the book category, but only 300,000 in CDs. This choice meant the capabilities of the computer - in organisation and selection - could be put to good use. Woman: Bookstore has certainly been very successful. Why do you think that is？ Man: Well, it's not been easy. For the first five years, it was a struggle raising funds and developing the right software. The ideas weren't the difficult bit. If you and I sat down here for an hour, we'd come up with a hundred good ideas. The hard bit is making those ideas work. There are several key elements, which for me were research, recruiting the right staff, and prioritising. Woman: And you're satisfied with your customer growth？ Man: Well, it was a bit slow at first but then it picked up and from May '97 we started to see our greatest growth. We went from a hundred and twenty million dollars annual sales revenue to two hundred and thirty million dollars by the end of that year, and from 340,000 customers to 15 million. 58% of them were repeat customers. By '98, sales had reached almost three hundred and ten million dollars. Woman: And is Bookstore's success reflected in its profits？ Man: Well, at the moment we're focusing on introducing ourselves to customers and we spend a lot on advertising. Anything else would be a poor management decision. But, of course, it's reflected in our final figures. It's not unusual for a four-year-old company like ours to be in an investment cycle. What is more unusual is for a young company like Bookstore to be sold on the stock market, which happened in July '97. Woman: Bookstore is well-known for its high- quality customer service. What is the secret of your success in this area？ Man: Well, firstly our books are delivered fast and any complaints are dealt with by email and what's important is that the email is always answered in a friendly way, with the emphasis on 'the customer is always fight'. In fact, customers sometimes feel guilty about complaining because Bookstore staff are so helpful! Regular customers are recognised when they go to our website, and we suggest titles to them, based on their previous purchases. Woman: Do you think Bookstore offers a better service than its competitors？ Man: Well, yes. We'd been in the market for about two years before most of our competitors started so we had a head start and although some have caught up now, we're still cheaper. Our book price includes tax and delivery. Most of our competitors' prices don't. But what's more important is that B A．he was earning yep/little in his job.

2. Yet the implication that rapid change is a new phenomenon is again misleading. If you measure the time it takes for a technology to become widely diffused, today's experience does not seem unusual. Take the car. The basic patent for an internal-combustion engine capable of powering a car was fried in 1877. By the late 1920s—50 years later—over half of all American households owned a car. 3. The comparable dates for the computer axe harder to tie down, but the first big computer, based on vacuum valves, was built in 1946. The transistor—the first semiconductor device—was invented at Bell Laboratories in 1948. The first patent for an integrated circuit was filed in 1959. Now, in 1999-50 years after the first one was built—around half of American households own a computer. The pace of introduction has been similar to that of the car. 4. You have to cheat, choosing only the date for the personal computer, say(mid-1970s), or the internet (ditto) to make it seem much more rapid. Comparing its diffusion among private users is, you might say, unfair to the computer, for that machine's main use is in businesses. On that measure, the best historical analogy is with electrification, and the spread of the electric dynamo into factories. 5. According to Paul David, a historian at Stanford University in California, the first electricity-generating stations had been installed in New York and London in 1881, but it was well into the 1920s before the dynamo became widely used and started to raise productivity. The adoption of the computer in business has also been slow, and failed to have any measurable impact on productivity until very recently.

Why is it that so many mothers like mine think of themselves as second-class or something similar？ Where has this notion come from？ Have we males made them feel this way？ Has our society made "going to work" outside the home seem more important than what a house wife must face each day？ I would be very curious to see what would happen if a housewife went on strike. Dishes would pile up. Food in the house would run out. No meals would appear on the table. There would be no clean clothes when needed. High boots would be required just to make it through the house scattered with garbage. Walking and bus riding would increase. Those scout troops would have to break up. Charities would suffer. I doubt if the man of the house would be able to take over. Oh, he might start out with the attitude that he can do just as good a job, but how long would that last？ Not long, once he had to come home each night after work to more household duties. There would be no more coming home to a prepared meal; he'd have to fix it himself. The kids would all be screaming for something to eat, clean clothes and more bus fare money. Once he quieted the kids, he'd have to clean the house, go shopping, make sure that kids got a bath, and fix lunches for the next day. Once the kids were down for the night, he might be able to crawl into an unmade bed and, try to read the morning newspaper. No, I don't think many males are going to volunteer for the job. I know I don't want it. So, thanks, mom! I'll do what I can to create a national holiday for housewives. It could be appropriately called Wonder Woman Day. By what means do the children of the author's family go to school？ A．They take school bus. B．They take a taxi. C．Their mother drives for them. D．Scout troop sends them to school.

A．discount B．account C．receipt D．income
