单选题Language When most of us think about language, we think first about words. Thus, the hardest part of learning a foreign language may seem to be memorizing 【51】 vocabulary; when we observe a child first acquiring speech, we talk of his progress 【52】 a matter of learning new words. We are also 【53】 to feel that the adult speaker with the largest vocabulary has the best 【54】 of English. To think 【55】 a language as just a stock of words is 【56】 , quite wrong. Words alone do not 【57】 a language; a grammar is 【58】 to combine them in some intelligible way. Moreover, words are relatively easy to learn, and indeed all of us go 【59】 learning them all our 【60】 . They are also the 【61】 stable part of language. Words come into 【62】 , change their pronunciations and meanings, and disappear completely all with comparative ease. Yet it is true that the 【63】 is focus of language. It is in words 【64】 sounds and meanings interlock to allow us to 【65】 with one another, and it is words that we arrange together to make sentences, conversations and discourse of all kinds. Thus we have a paradox in that the most short-lived part of language is also the centre where meaning, pronunciation, and grammar come together.

单选题A Life with Birds For nearly 17 years David Cope has worked as one of the Tower of London"s yeoman warders, 1 known to tourists as beefeaters. David, 64, lives in a three-bedroomed flat right at the 2 of the Byward Tower, one of the gatehouses. " 3 our bedroom we have a marvelous view of Tower Bridge and the Thames," says David. The Tower of London is famous 4 its ravens, the large black birds which have lived there for over three centuries. David was immediately fascinated by the birds and when he was 5 the post of Raven Master eight years ago he had no 6 in accepting it. "The birds have now become my life and I"m always 7 of the fact that I am 8 a tradition. The legend says that if the ravens leave the Tower, England will fall to enemies, and it"s my job to 9 sure this doesn"t happen!" David 10 about four hours a day to the care of the ravens. He has grown to love them and the 11 that he lives right next to them is ideal. "I can 12 a close eye on them all the time, and not just when I"m working." 13 , David"s wife Mo was not 14 on the idea of life in the Tower, but she too will be sad to leave when he retires next year. "When we look out of our windows, we see history 15 around us, and we are taking it in and storing it up for our future memories."

单选题My First Job I was six when I joined my father and two elder brothers at sunrise in the fields of Eufaula, Oklahoma. 1 the time I was eight I was helping Dad fix up old furniture. He gave me a cent for every nail I 2 out of old boards. I got my first real job, at JM"s Restaurant in town, when I was 12. My main responsibilities (职责) were 3 tables and washing dishes, but sometimes I helped cook. Every day after school I would 4 to JM"s and work until ten. Even on Saturdays, I worked from two until eleven. At that age it was difficult going to work and 5 my friends run off to swim or play. I didn"t necessarily like work, but I loved what working 6 me to have. Because of my job I was always the one buying when my friends and I went to the local bar Tastee Freez. This made me 7 . Word that I was trustworthy and hard-working 8 around town. A local clothing store offered me credit (赊账) 9 I was only in the seventh grade. I immediately 10 a $68 sports coat and a $22 pair of shoes. I was 11 only 65 cents an hour, and I already owed the storekeeper $90 ! So I learned 12 the danger of easy credit. I paid it off as soon as I could. My first job taught me self-control and responsibility, it brought me a 13 of personal satisfaction few of my friends had experienced. As my father, 14 worked three jobs, once told me, "If you 15 sacrifice (奉献) and responsibility, there are not many things in life you can"t have. " How right he was!

单选题The Fat Problem that Men Face It is a pleasure to see men of a certain age worrying about their weight. Listening to them is not such a pleasure. Because the men are new at the game, they don't hesitate to discuss the fat problem incessantly. However women of the same age do not discuss the fat problem, especially not in mixed company. They prefer to face the problem with quiet dignity. Discussing the problem might only draw attention to some stray body part that may be successfully tucked away under an article of clothing. The age at which a man begins to explore the fat problem can vary. The actual problem can manifest itself in the early 30's, but broad-range discussion usually starts later. There are early nonverbal symptoms. I've watched the rugged journalist who shares my apartment sneak by with a Diet Coke. His shirts are no longer neatly tucked in to display a trim waist. Recently he has begun to verbalize his anxiety. He tells me, with a sheepish grin, that he is taking his suits to Chinatown to have them "tailored". Still-older men have lost their dignity and rattle on unabashedly. Often wives and children play important roles in their fat-inspection rituals. Take my oldest brother, a former college football player. His daughter says that several times a day he will stand at attention and call out, "Fat, medium or thin?" She knows the correct answer medium. Thin would be an obvious stretch, and fat may not get her that new video. According to his wife, he stands in front of the mirror in the morning(before the day's meals take their toll),puts his hands behind his head and lurches into a side bend, then clutches the roll that has developed and says, "Am I getting fatter? "His wife is expected to answer, "You look like you may have lost a few pounds. " And then there are the ex-husbands a pitiful group. They are extremely vocal. When I go to the movies with one, he confides that he is suffering from great hunger because he is dieting. He hasn't eaten since the pancakes and sausages he wolfed down that morning. He pauses in his monologue while he buys his popcorn. After the movie, we sprint to a restaurant, where he again pauses to devour a basket of bread. Before he orders his chaste salad and soup, he grows plaintive. Do I think he's fat?

单选题Internet-based Instruction By almost any measure, there is a boom in Internet-based instruction. In just a few years, 34 percent of American universities have begun offering some form of distance learning (DL), and among the larger schools, it"s closer to 90 percent. If you doubt the popularity of the trend, you probably haven"t heard of the University of Phoenix. It grants degrees entirely on the basis of online instruction. It enrolls 90,000 students, a statistic used to support its claim to be the largest private university in the country. While the kinds of instruction offered in these programs will differ, DL usually signifies a course in which the instructors post syllabi (课程大纲), reading assignments, and schedules on Websites, and students send in their assignments by e-mail. Generally speaking, face-to-face communication with an instructor is minimized or eliminated altogether. The attraction for students might at first seem obvious. Primarily, there"s the convenience promised by courses on the Net: you can do the work, as they say, in your pajamas (睡衣). But figures indicate that the reduced effort results in a reduced commitment to the course. While drop-out rates for all freshmen at American universities is around 20 percent, the rate for online students is 35 percent. Students themselves seem to understand the weaknesses inherent in the setup. In a survey conducted for eCornell, the DL division of Cornell University, less than a third of the respondents expected the quality of the online course to be as good as the classroom course. Clearly, from the schools" perspective, there"s a lot of money to be saved. Although some of the more ambitious programs require new investments in servers and networks to support collaborative software, most DL courses can run on existing or minimally upgraded (升级) systems. The more students who enroll in a course but don"t come to campus, the more the school saves on keeping the lights on in the classrooms, paying doorkeepers, and maintaining parking lots. And, while there"s evidence that instructors must work harder to run a DL course for a variety of reasons, they won"t be paid any more, and might well be paid less.
