1、大学英语四级 223 及答案解析(总分：746.57，做题时间：130 分钟)一、Writing (30 minutes)(总题数：1，分数：30.00)1.For this part, you are allowed 30 minutes to write a letter oat thanks. You should write at least 120 words, and base your composition on the outline given below in Chinese: 假设你过生日时收到了 Lucy 让人送来的鲜花，写信向她表示感谢。信的内容应包括： 1. 表达

2、感谢之意； 2. 提出回报对方； 3. 期待对方做客。 （分数：30.00）_二、Reading Comprehensio(总题数：1，分数：71.00)How Should You Build up Your Vocabulary Exactly what do you do during a normal day? How do you spend your time? Paul T. Rankin very much wanted an answer to that question. To get it, he asked sixty-eight individuals to keep

3、 an accurate, detailed record of what they did every minute of their waking hours. When he consolidated (巩固) his findings, he discovered that the average individual spent 70 percent of his waking time doing one thing only-communication. That meant either reading, writing, speaking or listening. Put

4、that evidence alongside of the research findings uncovered by the Human Engineering Laboratories. In exploring aptitudes and careers involving, among other things, data from 30,000 vocabulary tests given yearly, they discovered that big incomes and big vocabularies go together. Vocabulary, more than

5、 any other factor yet known, predicts financial success. And it all fits. Each word you add to your vocabulary makes you a better reader, writer, speaker and listener. Furthermore, linguistic scientists are quick to point out that we actually think with words. If that is so, new words make us better

6、 thinkers as well as communicators. No wonder more words are likely to mean more money. What better reason for beginning right now to extend your vocabulary? Take reading. What exactly do you read? Common sense says you read words. Research confirms that fact. “Vocabulary in context“ contributes 39

7、percent to comprehension. That s more than any other factor isolated and studied-even more than intelligence. And “word discrimination“ contributes more to speed of reading than any other factor-28 percent. In short, your efforts to improve vocabulary will pay off in both comprehension and speed. Su

8、ppose, as you re reading along, you lumtebs across a strange word. Did you find your self stopping for a closer look at lumtebs? Pardon the spelling slip. That s actually the word stumble (偶然发现). The letter just got mixed around. Obviously you now know that strange words do slow you down-or even sto

9、p you completely. Furthermore, strange words hinder (妨碍) comprehension. Which is easier to understand, “eschew garrulity“ or “avoiding talking too much“? What you need is a vital ,dynamic approach to vocabulary building. Hybrid (混合种) corn combines the best qualities of several varieties to ensure ma

10、ximum productivity. A hybrid approach to vocabulary should, in the same way, ensure maximum results. That s why you should use the CPD formula. Through Context When students in a college class were asked what should be done when they came across an unknown word in their reading, 84 percent said, “Lo

11、ok it up in file dictionary.“ If you do, however, you short-circuit the very mental processes needed to make your efforts most productive. But there s another reason. Suppose someone asks you what the word fast means. You answer, “speedy or swift“. But does it mean that in such contexts as “fast col

12、or“, “fast woman“, or “fast friend“? And if a horse is fast, is it securely tied or galloping (飞驰) at top speed? It could be either. It all depends. On the dictionary? No, on context-on how the word is actually used. After all, there are over twenty different meanings for fast in the dictionary. But

13、 the dictionary doesnt tell you which meaning is intended. That s why it makes such good sense to begin with context. Through Word Parts Now for the next step. Often unfamiliar words contain one or more parts, which, if recognized, provide definite help with meaning. Suppose you read that someone “h

14、ad a predilection for reading mysteries“. The context certainly isnt too helpful. But do you see a prefix, suffix or root that you know? Well, there s the familiar prefix pre-, meaning “before. Look back at the context and try inserting “before“. Reading mysteries apparently comes “before“ other kin

15、ds of reading. Yes, a predilection-or preference is something put “before“ something else. Or take the word monolithic. Try to isolate the parts. There is the prefix mono-, meaning “one“, and the root lith, meaning “stone“. Finally, there s the suffix -ic, meaning “consisting of“. Those three parts

16、add up to this definition: “consisting of one stone“. To speed up your use of word parts, you will be introduced to the fourteen most important words in the English language. The prefix and root elements in those few words are found in over 14,000 words of desk dictionary size. With those amazingly

17、useful shortcuts, you can build vocabulary, not a snail s pace, one word at a time, but in giant strides, up to a thou sand words at a time. Your second step, then, is to look for familiar word parts. If they do not give you exact meanings, they should at least bring you much closer. Through the Dic

18、tionary Now you can see why you should consult the dictionary last, not first. Youve looked carefully at the context. Youve looked for familiar word parts. Now you play Sherlock Holmes an exciting role. You hypothesize. In light of context or word parts, you try to solve a mystery. What exactly does

19、 that strange word mean? Only after you go through the mental gymnastics to come up with a tentative definition should you open the dictionary to see if you re right. After all, those first two steps or approaches spark a stronger than usual interest in that dictionary definition. You re now persona

20、lly involved. Did you figure out the word meaning? Your heightened interest will lead to a better memory of both word and meaning. It also encourages your development of the habits needed to accelerate your progress. And when you see in black and white the definition you had expected, what a feeling

21、 of accomplishment is yours. In that way, the CPD Formula provides the exact dynamic interplay of approaches for maximum effectiveness. Well, there it is, your new formula Context, Parts, Dictionary. Use it! The exercises that follow will give you specific, step-by-step help in sharpening your aware

22、ness of contextual clues, learning the most useful word parts, and using the dictionary with increased accuracy and ease. The results will be like the money in the bank. （分数：71.00）(1).This passage is meant to teach readers how to enlarge their vocabularies by means of the CPD Formula. （分数：7.10）A.YB.

It has been known to man fo

42、r at least 3,000 years, but has come into common use only in modern times. Until quite recently it was considered as a medicine and as a luxury for the very rich only. Sugar is, then, very important to our civilization. But what exactly is it? Of course, most of us recognize sugar immediately as the

43、 sweet material which we put in coffee or cakes. This common form of sugar is derived from two plants: the sugar cane (a type of grass which grows to a height of twenty feet) and the sugar beet (which grows underground). But there are in fact many types of sugar, and the chemist recognizes hundreds

44、of different varieties, each coming from a different source. About 90% of the sugar produced as food. Only 10% is used in industry for purposes other than food production. Yet sugar has great possibilities for use as the basis of chemicals. It can even be used for making plastics. In the future thes

45、e potential uses will certainly be developed more than in the past. There are many reasons why we should increase the production of sugar. Most important is that it is one of the most highly concentrated of energy foods. Thus sugar cane and beet produce an average of 7, 000,000 calories per acre. In

46、 this way they have the advantage over potatoes which give only 4,000,000, while figure for wheat and beans is 2,000,000 each. So three acres of land growing wheat and potatoes give only slightly more energy than one acre of sugar. （分数：177.50）(1).The heading of Paragraph one may be_.（分数：35.50）A.What
