单选题{{B}}Directions:{{/B}}Read the following text. Choose the best word(s) for each numbered blank and mark A, B, C or D on ANSWER SHEET 1. Speech, whether oral or written, is a used commodity. If we are to be heard, we must {{U}}(1) {{/U}} our words from those {{U}}(2) {{/U}} to us within families, peer groups, societal institutions, and political networks. Our utterances position us both in an immediate social dialogue {{U}}(3) {{/U}} our addressee and, simultaneously, in a larger ideological one {{U}}(4) {{/U}} by history and society. We speak as an individual and also, as a student or teacher, a husband or wife, a person of a particular discipline, social class, religion, race, or other socially constructed {{U}}(5) {{/U}}. Thus, to varying degrees, all speaking is a {{U}}(6) {{/U}} of others' words and all writing is rewriting. As language {{U}}(7) {{/U}}, we experience individual agency by infusing our own intentions {{U}}(8) {{/U}} other people's words, and this can be very hard. {{U}} (9) {{/U}}, schools, like into churches and courtrooms, are places {{U}}(10) {{/U}} people speak words that are more important than they are. The words of a particular discipline, like those of "God the father" or of "the law," are being articulated by spokespeople for the given authority. The {{U}}(11) {{/U}} of the addressed, the listener, is to acknowledge the words and their {{U}}(12) {{/U}}. In Bakhtin's {{U}}(13) {{/U}}, "the authoritative word is located in a distanced zone, organically connected with a {{U}}(14) {{/U}} that is felt to be hierarchally higher." {{U}} (15) {{/U}}, part of growing up in an ideological sense is becoming more "selective" about the words we appropriate and, {{U}}(16) {{/U}}, pass on to others. In Bakhtin's {{U}}(17) {{/U}}, responsible people do not treat {{U}}(18) {{/U}} as givens, they treat them as utterances, spoken by particular people located in specific ways in the social landscape. Becoming alive to the socio-ideological complexity of language use is {{U}}(19) {{/U}} to becoming a more responsive language user and, potentially, a more playful one too, able to use a {{U}}(20) {{/U}} of social voices, of perspectives, in articulating one's own ideas.

单选题House-price falls are gathering momentum and are spreading across the UK, according to a monthly poll of surveyors which on Monday delivered its gloomiest reading for nearly 12 years. Fifty-six per cent of surveyors contacted by the Royal Institution of Chartered Surveyors reported price falls in the three months to October. Only 3 per cent saw prices rise in their area, compared with 58 per cent as recently as May. There was further evidence of slowing activity in the property market as the number of sales per surveyor dived to a nine-year low. Unsold stock on agents' books has increased 10 per cent since the summer. Ian Perry, Rics' national housing spokesman, said it was now very clear that buyers were unsettled by higher interest rates. The Bank of England raised rates five times to 4. 75 per cent over the last year to cool the property boom. But he also blamed comments by Mervyn King, the Bank's governor, and misleading media headlines for "injecting additional uncertainty into the market by continued speculation over more serious price declines". "Mervyn King presumably felt that he had to be more explicit in the summer when people were still buying. His warnings of a drop in property prices then have had the desired effect. "But our concern now is that the pendulum is swinging too far," be said. Last week, the Bank's monetary policy committee predicted for the first time that "house prices may fall modestly for a period" in its November inflation report. The Nationwide and Halifax mortgage lenders both showed a modest monthly decline in house prices in their latest loan approval data. Although the majority of surveyors expect prices to fall further in the next three months, Mr. Perry stressed there were signs of stabilizing demand from buyers in London. "London tends to be ahead of the rest of the market. And agents are telling us that more people are looking to buy. It is much better than it was," Mr. Perry said. However, falling prices continued to spread from the South of England as surveyors reported the first clear decline in prices in Yorkshire and the Humber, the north and the north west. Scotland remained the only region with rising prices.

单选题Long bus rides are like television shows. They have a beginning, a middle, and an end—with commercials thrown in every three or four minutes. The commercials are unavoidable. They happen whether you want them or not. Every couple of minutes a billboard glides by outside the bus window. "Buy Super Clean Toothpaste. " "Drink Root Beer. "" Fill up with Pacific Gas. " Only if you sleep, which is equal to turning the television off, are you spared the unending cry of "You Need It! Buy It Now!" The beginning of the ride is comfortable and somewhat exciting, even if you' ve traveled that way before. Usually some things have change—new houses, new buildings, sometimes even a new road. The bus driver has a style of driving and it' s fun to try to figure it out the first hour or so. If the driver is particularly reckless or daring, the ride can be as thrilling as a suspense story. Will the driver pass the truck in time? Will the driver move into the right or the left-hand lane? After a while, of course, the excitement dies down. Sleeping for a while helps pass the middle hours of the ride. Food always makes bus rides more interesting. But you' ve got to be careful of what kind of food you eat. Too much salty food can make you very thirsty between stops. The end of the ride is somewhat like the beginning. You know it will soon be over and there' s a kind of expectation and excitement in that. The seat, of course, has become harder as the hours have passed. By now you' ve sat with your legs crossed, with your hands in your lap, with your hands on the armrests—even with your hands crossed behind your head. The end comes just at theright time. There are just no more ways to sit.
