单选题{{B}}Passage Two{{/B}} A university graduate described as a "respectable and intelligent" woman is seeking professional help after being convicted of shoplifting for the second time in six months. Ana Luz, recently studying for her PhD, has been told she could end up behind bars unless she can control the desire to steal from shops. Luz, who lives with her partner in Fitzwilliam Road, Cambridge, admitted stealing clothes worth ￡9.95 from John Lewis in Oxford Street, London, on March 9. Phillip Lemoyne, prosecuting, said Luz selected some clothes from a display and took them to the ladies' toilet in the store. When she came out again she was wearing one of the skirts she had selected, having taken off the anti-theft security alarms. She was stopped and caught after leaving the store without paying, Mr. Lemoyne said. He added that she was upset on her arrest and apologized for her actions. Luz, 28, was said to have been convicted of shoplifting by Cambridge judges last October, but Morag Duff, defending, said she had never been in trouble with the police before that. "She is ashamed and embarrassed but doesn't really have any explanation why she did this," Miss Duff said. "She didn't intend to steal when she went into the store. {{U}}She is at a loss to explain it{{/U}}. She is otherwise a very respectable and intelligent young lady. She went to her doctor and asked for advice because she wants to know if there is anything in particular that caused her to do this." Judge David Azan fined Luz ￡50, and warned. "You've got a criminal record. If you carry on like this, you will end up in prison, which will ruin your bright future you may have." Luz achieved a degree in design at a university in her native Spain, went on to a famous university in Berlin, Germany for her master's degree and is now studying for a PhD at Cambridge University, UK.

单选题______ life pace continues to speed up, we are quickly losing the art of enjoyment.

单选题To improve the ______ is regarded as a good method to increase the farmer"s income in the south part of the country.

单选题Modern mass-production methods lower the cost of making goods, and thus give us better values. At the same time, American ingenuity (独创性) and science are constantly at work improving the quality of products. (79) In this way, better quality products at good values are continually being brought to the people of all income groups. As an example of how this worked, when facial tissues (面巾纸) were first put on the market in 1924, they were made in limited quantities and sold at 65 cents per box of 200. People like these facial tissues immediately and began asking for them when they went into different stores. Because there was such a demand for the product, manufacturers began making tissues in larger and larger quantities. Because the manufacturers were making tis-sues in greater quantities, their production costs were lowered, so that the price of tissues went down. (80) In the meanwhile, the quality of facial tissues was constantly improving, because more manufacturers went into the business of making tissues, and each manufac-turer strove to make his product better than his competitors'. Today, instead of costing 65 cents, a box of 200 tissues costs around one-third of that price, and they are both softer and stronger.When people are free to compete-when they are free to make more things and make them better-everyone benefits.

单选题Stressful environments lead to unhealthy such as poor eating habits, which ______ increase the risk of heart disease.

单选题For well over 2000 years the world's great religions have taught the virtues of a trust-ing heart. Now there is another reason to merit the wisdom of the ages: scientific evidence indicates that those with trusting hearts will live longer, healthier lives. As a result of the work published in the 1970s by two pioneering heart specialists, Meyer Friedman and Ray H. Rosenman, nearly every American is aware that blood Type A people are impatient, and easily moved to hostility (敌意) and anger. Many have come to believe that Type A's are at a much higher risk of suffering heart attack or dying of heart disease than others. The driving force behind hostilityis a cynical mistrust of others. If we expect others to mistreat us, we are seldom disappointed. This generates anger and leads us to respond with hostility. The most characteristic attitude of a cynic is being suspicious of the motives (动机) of people he doesn't know. Imagine you are waiting for an elevator and it stops two floors above for longer than usual. How inconsiderate! You think. In a few seconds, you have drawn hostile conclusion about unseen people and their motives.Meanwhile, your cynical mistrust is leading to noticeable physical consequences. Your voice rises. The rate and depth of your breathing increases. Your heart is beating faster and harder, and the muscles of your arms and legs become tight. You feel "charged up", ready for action.If you frequently experience these feelings, you may be at increased risk of developing serious health problems. Anger can add to the risk of heart and other diseases.
