单选题All the housewives who went to the new supermarket had one great ambition: to be the lucky customer who did not have to pay for her shopping. For this was what the notice just inside the entrance promised. It said : " Remember, once a week, one of our customers gets free goods. This May Be Your Lucky Day!" For several weeks Mrs. Edwards hoped, like many of her friends, to be the lucky customer. Unlike her friends, she never gave up hoping. The cupboards in kitchen were full of things which she did not need. Her husband tried to advise her against buying things but failed. She dreamed of the day when the manager of the supermarket would approach her and say," Madam, this is Your Lucky Day. Everything in your basket is free. " One Friday morning, after she had finished her shopping and had taken it to her car, she found that she had forgotten to buy any tea. She dashed back to the supermarket, got the tea and went towards the cash-desk. As she did so, she saw the manager of the supermarket approach her. " Madam," he said, holding out his hand, "I want to congratulate you! You are our lucky customer and everything you have in your basket is free!/

单选题Professor Kumar Bhatt, founder and head of Warwick Manufacturing Group (WMG), and Rob Meakin, a personnel director at Marconi, have developed a partnership to train engineers and managers to become e-literate. The New Knowledge Partnership will include a team of 40 Marconi managers in what Professor Bhatt calls electronic engineering management or E2. A wide range of engineering and non-engineering companies has expressed interest in these exciting programs. Professor Bhatt believes that e-commerce is changing the business environment to a huge extent. Many chief executives do not understand the power of the new technologies and, in some cases, are actually resisting change. He says, "as long as enough industry leaders realize its potential benefits, e-business will make possible a second productivity revolution in Britain. This could take the economy close to eliminating the still substantial competitiveness gap with its main rivals. Over the last five years in the US there has been a 30% improvement in manufacturing sector productivity because of information technology. In Britain we can achieve more than that and successful e-business will be worth billions to the UK economy." Already Britain makes more use of computer-aided design and manufacture (CAD/CAM) and management information technology systems than other European countries, and has a government that actively promotes e-business. But, observes Professor Bhatt, Britain has never used technology as a growth driver. "The thing about electronic engineering management is that you can keep your legacy systems; you just need to link those systems with an information engine. At the touch of a button it will allow project managers to see the status of a project, identify problems precisely and make virtually immediate decisions based on information that will be much more complete than in the past." The E2 program is the result of an alliance by the Warwick Manufacturing Group with America"s leading e-commerce study center, Carnegie Mellon. The latter will be responsible for training many of the Marconi managers in America, where the group has half its business. In Britain, Professor Bhatt has linked up with Sun Microsystems, Oracle and Parametric Technology, to set up a multi-million pound E2 design and manufacturing center at the university which will be used for training and research. Professor Bhatt believes that e-commerce is changing business to such an extent that WMG is likely to be renamed Warwick Electronic Manufacturing Group. But, he warns "The move to globalize because of e-commerce is racing ahead. Although the net allows British industry to overtake their European peers, it also offers Asian countries to leapfrog (跃过) the West. For the first time it is not the privilege of the western world because this technology is universal."

单选题Amy Johnson was a pioneer airwoman in Britain. She was born on July 1, 1903, in Yorkshire and lived there until 1923 when she went to Sheffield University to study for a BA. After graduation she took a job as a secretary to a London lawyer. At the same time she became interested in aviation, and to succeed in some project which would prove to the world that women could be as competent as men in a male-dominated field in those days. Early in 1930, she chose her objective: to fly solo to Australia and to break the previous record of 16 days. Her parents and some of her friends lent her money to buy a used airplane. Amy set off on May 5, 1930. Her route took her over Vienna and Baghdad. She was caught in a sandstorm and had to make an emergency landing in the desert. Six days later she landed in India. After experiencing much hardship, she finally reached Australia on May 24, completing a flight of 11,000 miles. She was the first woman to fly alone to Australia. In later years, she set several other records in flight history.
