Passage 1Shopping-bag ladies don’t beg publicly, but they do not refuse what is offered. Once a shopping-bag lady appears where you live, it is as hard to pass her by without giving her some money as it is to pay no attention to the collection box in church. And although you may not like it, if she chooses your doorway as her place to sleep in the night, it is as morally hard to turn her away as it is to do with a lost dog.Most shopping-bag ladies seem to be between the ages of 40 and 65. They wear layers of clothes even in summer time, with newspapers filled between the layers as something against bad weather.No one knows how many shopping-bag ladies there are in New York. The number is going up. Some persons and researchers spend a great deal of time taking care of or observing shopping-bag ladies and doing what they can to better the life lady hermits（隐士）who’re down.31．Shopping-bag ladies are ______.A. lady beggarsB. ladies who sell shopping-bagsC. ladies who make shopping-bagsD. Those who go hungry32．They fill newspapers between the layers of their clothes because ______.A.they are so poorB.they have no place to put themC.they want to hide themD.they have to use them to keep the cold out33．Which of the following statements is NOT true?A.There are more and more shopping-bag ladies in the United States.B.Shopping-bag ladies appear only in New York.C.Some people are helping shopping-bag ladies.D.Some people are engaged in their research on these shopping-bag ladies.Passage 2Relaxation therapy (=treatment). If you read the sentence out loud, your blood pressure will go up. If you talk to another person, it will go still higher. If the talk is with your boss, your pressure will go even higher. If you speak to someone of the opposite sex, your pressure may show less change if you’re married than if you’re single.Dozens of times each day, your blood pressure changes with what you’re feeling and doing. These “ups and downs”take place in everyone, but they are more severe in people with high blood pressure. That discovery is the basis for the newest therapy: controlling blood pressure by learning skills to control everyday stress.Many patients control their blood pressure with the relaxation response. This takes four simple things: a quiet environment, a comfortable position(sitting or lying down), the repeating of a word, prayer or phrase each time you breathe and having none of other thoughts.Something remarkable happens when you do this, according to research in Boston. Relaxation of the mind and body has the effect that some blood-pressure pills would have. What’s more, the blood pressure stays lower, just as it would with a pill, after you have stopped the relaxation and have returned to the stress of daily life.34. The first paragraph tells us the reason why your blood pressure goes up is that ______.A. you read aloud a sentenceB. the man you talk to is your bossC. you’re not marriedD. you’re nervous35. Which of the following statements is NOT true?A. One’s blood pressure changes many times every day.B. Your blood pressure changes with your feelings.C. When you’re doing different things, your blood pressure, perhaps, is different.D. The changes of blood pressure only happen to people with high blood pressure.36. The second paragraph shows us the basis of relaxation therapy is______.A. to reduce the going up of the pressureB. to control everyday stressC. to do less and say lessD. to think less and sleep morePassage 3The digital revolution, as exemplified by the Internet and electronic commerce, has shaken marketing practices to their core. In a recent paper, Wharton’s Jerry Wind, director of the SEI Center for Advanced Studies in Management, and co-author Vijay Mahajan, a marketing professor at the College of Business Administration of the University of Texas at Austin, examine the impact of digital marketing on concepts like pricing, when customers can propose their own prices (), or buyers and sellers can haggle independently in auctions ().The paper provides an overview of some of the emerging realities and new rules of marketing in a digital world, and outlines what the new discipline of marketing may look like in the early part of the new century.To begin with, say the authors, the rapid-fire growth of the Internet is helping to drive changes. “It is not just our computers that are being reprogrammed; it is customers themselves,”says Wind. “These emerging cyber consumers are like an alien race that have landed in the midst of our markets. They have different expectations and different relationships with companies from which they purchase products and services.”For one thing, cyber consumers expect to be able to customize everything —from the products and services they buy and the information they seek, to the price they are willing to pay. And with digital technology opening new channels for gaining information, they are more knowledgeable and demanding than previous consumers.Digital customers can also sort products based on any desired attribute, price, nutritional value, or functionality, and they can easily obtain third-party endorsements and evaluations, tapping the experience of other users. “Companies that cannot meet their demands and expectations will be at a loss,”says Wind.37. The passage was most likely to be quoted from______.A. an overview of a paperB. an introduction to a bookC. a book on digital revolutionD. a paper discussing digital revolution38. The paper mentioned in this paper was written by______.A. Jerry WindB. Vijay MahajanC. Jerry Wind and Vijay MahajanD. an anonymous39. From the third paragraph, we can infer that______.A. the customers are also reprogrammed by computersB. e-business companies need be more knowledgeable about cyber consumersC. cyber consumers are a group of strange peopleD. cyber consumers came from outer space40. Compared with traditional customers, the emerging cyber consumers______.A. are more difficult to satisfyB. have less knowledge about businessC. have more problems with pricesD. are less willing to buy products and services四、单词汉译英（本大题共15小题，每小题1分，共15分）根据给出的汉语词义和规定的词类写出相应的英语单词。
