单选题There are many different kinds of peaches (桃). One clear difference is the one between clingstone--fruit in which the flesh is stuck to the seed inside--and freestone --that in which the seed floats freely. Customers prefer freestone peaches because they don't want to struggle to get the flesh away from the seed. And that's how it goes in stone fruit land. Plant breeders (培育者) are trying all the time to improve the old favorites. Frequently, the changes are designed to meet the demands of the growers or packers. One very delicious family of peach varieties has nearly disappeared because it forms a small" beak" at the bottom of the fruit. That little point is likely to break during packing and shipping, opening the door to spoilage (腐烂). This is certainly not to say that the wants of customers are not important. In fact, they drive some of the most important changes. One thing customers like is red--lots of red. Peaches used to be prized for golden skin ; now people are buying red, regarding it as a sign of ripeness. But red has a hold on people. There's a story told by those in the stone fruit industry about a marketing experiment. A group of people were given two peaches : one a fairly tasteless red variety, the other a great-tasting gold. Sitting around, tasting and talking about the fruit, the group all agreed that the gold was a much better peach and that was the one they would buy. Then, on the way out the door, they were offered boxes of peaches as a thank-you gift. One held the preferred golden fruit, the other the red. To a person, they picked the red fruit to take home. Red sells.

单选题Every year landslides (滑坡) cause 25 to 50 deaths and $1.5 billion in damage in the United States. They account for 15 percent of the deaths from natural disasters in Europe. And there was ever a single event killed more than 200 people in the Philippines. Sending workers to stabilize mountainsides using steel bars and cement (水泥) can help prevent disasters, but it introduces new difficulties. Shaking drills produce harmful dust and loosen heavy, dangerous debris (岩屑). "It"s quite a risky job," says Giorgio Pezzuto of D"Appolonia, an engineering company in Italy. D"Appolonia, working with eight other companies, may have an answer: a three-ton robot called Roboclimber. "The idea is to operate a machine far away that can drill without a human being on board," says Pezzuto, the manager for the project, which is supported by the European Commission. Engineers claim that the machine will be faster and cheaper than manual labor. The robot, a large radio-controlled four-legged mechanical spider, has cost at least $2 million so far. The final product should be able to climb unstable mountainsides, drill holes, insert bars and cement, and collect data on the stability. Testing should begin in May.

单选题{{B}}Text 2{{/B}} Pat O'Burke was a poor Irishman with a large family, and one morning, waking up very early from cold and hunger, he decided to go shooting in a wood near his cottage. The wood belonged to Lord Northwood, a rich gentleman, and Pat had no right to go there, but in it there were swarms of rabbits and flocks of birds that were good to eat, and Pat determined to take the risk. Suddenly he saw the owner, with a group of friends, coming towards him in the wood. There was a look of anger on Lord Northwood's face as he caught sight of the gun in Pat's hands. Pat's heart sank with fear, but he saw there was no hope of escape, so he walked boldly up to the company and said to Lord Northwood, "Good morning, sir, and what has brought you out so early this morning?" Lord Northwood, rather surprised, said he and his friends were taking a little exercise to get an appetite for their breakfast. Then looking at Pat with suspicion, he said, "But why are you out so early in the morning? Well, sir," said Pat, "I just came out to see if I could get a breakfast for my appetite." The whole crowd burst into laughter at Pat's ready wit, and with a smile Lord Northwood walked on, leaving Pat to try his luck with the rabbits.

单选题{{B}}D{{/B}} Computer programmer David earns $40,000 a year designing new computer games, yet he cannot find a bank to let him have a credit card. Instead, he has been told to wait another two years until he is 18. The 16-year-old works for a-small firm in Liverpool. David's firm releases two new games for the fast growing computer market each month. But David's biggest headache is what to do with his money. Even though he earns a lot, he cannot drive a car, take out a mortgage(抵押货款), or get credit cards. "I got the job because the people who run the firm knew I had already written some programs." he said. David spends some of his money on records and clothes, and gives his mother 50 pounds a week. "Unfortunately, computing was not part of our studies at school," he said, "but I had been studying it in books and magazines for four years in my spare time. I knew what I wanted to do and never considered staying on at school." David added, "I would like to earn a million and I suppose early retirement is a possibility. You never know when the market might disappear."
