4. l) Standing in the burned-out shell of my living room was a shocking experience. Above my head were charred beams, all that remained of our ceiling. In front of me, where our television and stereo had once stood, were twisted pieces of metal and chunks of blackened glass. Strangely, some items seemed little damaged by the fire. For example, I could see the TV tuner knob and a dusty CD under the rubble. I walked through the ashes until I came to what was left of our sofa. Behind the sofa had been a wall of family photographs. Now, the wall and the pictures were gone. I found only a water-logged scrap of my wedding picture.

Weeks before the New Year’s Day, my mother would let me help her send out New Year’s cards and go shopping with her. In the crowded markets, I bought firecrackers, like all the ot her kids.

This festival is a cheerful occasion, for on this day, the dead are said to return to their homes and they are welcomed by the living. As they are expected to be hungry after their long journey, food is firstly prepared and laid out for them. Also prepared and specially made are the lanterns, which are hung outside each house to helpthe dead to find their way. Afterward people keep dancing and singing all night long till the early morning. Then the food that had been laid out for the dead is thrown into a river or into the sea as it is considered unlucky for anyone living to eat it. In towns that are near the sea, the tiny lanterns, which had been hung in the streets the night before, are placed into the water. This signals the end of the festival. Thousands of lanterns then slowly drift out to sea guiding the dead on their return journey to the other world. This is a moving spectacle, for crowds ofpeople stand on the shore watching the lanterns drifting away until they can be seen no more.6.According to the Chinese Lunar calendar, the 15th day of the eighth lunar month is the day for the Mid-Autumn Festival, and the day usually falls on one of the days in the latter half of Septem ber. For this occasion people need to buy moon cakes in advance. And when that evening comes with a full moon rising, Chinese families begin to have a big dinner together. The family members enjoy many delicacies, including sweet or salty moon cakes as well as some special food like taros and young soy beans. For those who are absent from the family, moon cakes have already been s ent to them days before. When the family enjoy all of these, they will look up at the full moon, ch atting or missing their faraway relatives or friends. For them, the full moon symbolizes “reunion.”Such feelings and scenes are fully expressed by a Chinese saying: the moon at home is exceptiona lly brighter.3.1) Paragraph A follows Pattern 2, which uses one extended example to illustrate the controlling idea.

The second bad feature of the job was the pay.Specific details:I was getting the minimum wage at that time, $1.25 an hour, plus a minimum of a nickel extra for working the night shift.3. The worst feature of the apple plant job was the working conditions.Specific details:1) During work we were limited to two 10-minute breaks and an unpaid half-hour for lunch.2) The steel floors of the trucks were like ice; the quickly penetrating cold made my feet feel like stone.Concluding sentence: I felt humiliated by the poverty that forced me to do such a bitter job.4.Logical sequence of the sentences:3, 6, 1, 8, 2, 4, 7, 5,Pattern: It follows Patten 1 and uses many examples to illustrate the controlling idea.5.(1) For example (2) Furthermore (3) In still another instance(4) Even (5) his (6) these (7) contemporary6.Examples 2, 3 and 5 are relevant and specific.

For my grandmother, who was born before the turn of the century, it was rude to start eating before everyone else was served. It was also very rude for children or younger people to interrupt older people when they were speaking. For my dad, who grew up during the Depression and the Second World war, it was rude not to say hello to a clerk in the store, and he thought my brothers and I were rude when we made unfavorable remarks about him.b) Today, rudeness is not just a matter of forgetting small courtesies.

In the magazine industry, for example, mass magazines have routinely been replaced by magazines aimed at very specific audience. Suburban, community, and neighborhood newspapers have boomed, while many large metropolitan newspapers have declined. Movies have gone after particular audiences and tastes. Mini-theaters attract small audiences. Network radio has been superseded by AM and FM stations aimed at very specific audiences. The CB radio boom is an example of the success of an extremely personal form of communication. Television is headed in the same direction. That can mean something for everyone—and an endless string of choices. In brief, each medium is moving toward more and more specialization.Paragraph Two:How have advertisements aff ected people’s lives?Radio commercials get millions of teenagers to shop for the products made “exclusively” for them. Similarly, magazine, advertisements, showing gorgeous models dressed in the latest style, convince women that they must buy a new wardrobe in order to remain fashionable. And newspapers, too, are filled with ads which stress the need to “buy now at bargain prices” everything form pills to major household appliances. Finally, TV programs, also, are interrupted every five minutes with commercials urging people to try a new detergent, to compare their brand of cigarettes with another, or to drink a different kind of beer. Thus, mass media advertising serves mass production by getting people to buy, buy and buy.5.A.

TV serials or dramas may oversimplify complex social and psychological problems.(1) enjoying simple-minded soap operas and stereotyped characters(2) giving a false picture of realityC.

Sentence 2 shows the progression of objects from the ends of the table to the center. Sentence 3 focuses on the objects in the middle of the table. Thus the reader can visualize the scene very vividly.2) The prepositional phrases of location and direction are:at one end of the table, at the other end of the table, on a bed of creased paper, round its shin, beside this, between these rival ends, on which lay bunches of purple raisins, on which lay a solid rectangle of Smyrna figs, in which stood some tall celery stalks, in the center of the table3) The verbs used are primarily static verbs, like “to be,”“lay,” and “stood,” which reinforce the spatial pattern and contribute to the central impression. They are effective for the purpose as the point of view is that of an observer who is close to the scene being described.3.

For my grandmother, who was born before the turn of the century, it was rude to start eating before everyone else was served. It was also very rude for children or younger people to interrupt older people when they were speaking. For my dad, who grew up during the Depression and the Second World war, it was rude not to say hello to a clerk in the store, and he thought my brothers and I were rude when we made unfavorable remarks about him.b) Today, rudeness is not just a matter of forgetting small courtesies. Rudeness is also being impatient and pushy. When people cut into my lane when I am driving or shove in front of me in line, I get very angry.3.1) pattern: single effect and multiple causes.2) causes(1) got drunk at the party(2) had taken the drug of Accutane(3) adolescent depressionEffect:Bart Jr’s suicide4.Logical sequence of the sentences:2, 4, 1, 3, 6, 5,Pattern of cause and effect:single effect and multiple causes.5.Task one.Topic: Society itself may be producing the distortions of personality, mental illness, and emotional instability.Causes1) society’s compartmentalizing2) society’s competitive demands3) inability to rebelEffectDistortions of personality, etc.3..1) Topic: University Students’ EntertainmentTopic sentence: University students’ entertainment can be divided into three categories according to where it takes place.Division:a) entertainment at homeb) entertainment on campusc) entertainment elsewhere2) Topic: Roles of Young Married Women in SocietyTopic sentence: The average young married woman in today’s society has her life divided into three different roles.Division:a) the role of lifeb) the role of motherc) the role of self3) Topic: NeighborsTopic sentence: Neighbors fall into three categories according to their different attitudes towards you.Division:a) those who are friendlyb) those who are indifferentc) those who hate you4.1) Out: firm, single basis: size2) Out: fatigue, single basis: field3) Out: Baptism, single basis: branch4) Out: seashore, single basis: time5..Logical sequence of the sentences:7, 3, 10, 9, 1, 5, 8 ,4, 2 ,11, 6,Subject: Christmas giftsTopic sentence: Christmas gifts can be divided into three groups, according to their after-Christmas fate.Division:a) those that are welcomed and put into use very soonb) those that are halfway between being hated and lovedc) those that you banish as soon as possible.Concluding sentence: By New Year’s Day, you have either used, stored or disposed of each of your Christmas gifts.6.(1) types (2) Though (3) Finally (4) however (5) Even though (6) Before (7) third (8) If(9) Then (10) these3.Pattern: point-by-pointSubject 1: Western HomesPoint:Room function: Each room has its own function.Table: Each home has several tables for different functions.

In the magazine industry, for example, mass magazines have routinely been replaced by magazines aimed at very specific audience. Suburban, community, and neighborhood newspapers have boomed, while many large metropolitan newspapers have declined. Movies have gone after particular audiences and tastes. Mini-theaters attract small audiences. Network radio has been superseded by AM and FM stations aimed at very specific audiences. The CB radio boom is an example of the success of an extremely personal form of communication. Television is headed in the same direction. That can mean something for everyone—and an endless string of choices. In brief, each medium is moving toward more and more specialization.Paragraph Two:How have advertisements affected people’s lives?Radio commercials get millions of teenagers to shop for the products made “exclusively” for them. Similarly, magazine, advertisements, showing gorgeous models dressed in the latest style, convince women that they must buy a new wardrobe in order to remain fashionable. And newspapers, too, are filled with ads which stress the need to “buy now at bargain prices” everything form pills to major household appliances. Finally, TV programs, also, are interrupted every five minutes with commercials urging people to try a new detergent, to compare their brand of cigarettes with another, or to drink a different kind of beer. Thus, mass media advertising serves mass production by getting people to buy, buy and buy.5.A. Programs on TV tend to have a high level of maturity.(1) fostering maturity at early age or hindering maturity(2) misleading children to imitating scenes on TVB. TV serials or dramas may oversimplify complex social and psychological problems.(1) enjoying simple-minded soap operas and stereotyped characters(2) giving a false picture of realityC. Informative and cultural programs are frequently interrupted by vulgar advertising.(1) too many commercials(2) an insult even to the intelligence of a moronGeneralization: In brief, it is harmful and damaging for children to watch too much television.6.(1) Thus (2) When (3) also (4) however(5) Moreover (6) indeed (7) also (8) Yet(9) and (10) Thus3.The description centers on one trait of personality: Uncle Amo’s being ordinary and average in life.4.There are obviously three methods used: comparison (1), generalization (2, 4), and cause-effect3.4.1) For exampl e, some people don’t like to stay at home after work.2) I once stopped drinking for a while.3) The world we live in is changing every day.4) And the price of tobacco has been going up on the international market.5) A lot of people have successfully given up smoking now.5.1) The thesis statement is “there are minor differences between them in three areas.” It is the second sentence in the first paragraph.3)By repetition of key words: difference, British English, American English.By using transitional words and phrases: in terms of, in addition to, second, third, generally speaking.6.Task One(1) usually (2) often (3) Since (4) on the other hand(5) also (6) but (7) AlthoughTask Two3.Sentences that tell: 1, 3, 6 Sentences that show: 2, 4, 55.Logical sequence of the sentences: 8, 3, 7, 1, 5, 9, 13, 2, 6, 12, 4, 11, 106.(1) While(2) in the morning(3) in the evening(4) While(5) until(6) while(7) before(8) at six o’clock(9) As soon as(10) Unfortunately(11) What’s more(12) After(13) the next morning(14) later(15) Luckily(16) until(17) at last3.

Sentence 2 shows the progression of objects from the ends of the table to the center. Sentence 3 focuses on the objects in the middle of the table. Thus the reader can visualize the scene very vividly.2) The prepositional phrases of location and direction are:at one end of the table, at the other end of the table, on a bed of creased paper, round its shin, beside this, between these rival ends, on which lay bunches of purple raisins, on which lay a solid rectangle of Smyrna figs, in which stood some tall celery stalks, in the center of the table3) The verbs used are primarily static verbs, like “to be,” “lay,” and “stood,” which reinforce the spatial pattern and contribute to the central impression. They are effective for the purpose as the point of view is that of an observer who is close to the scene being described.senses ExamplesSight Shape solid, blocks, round, leaf-shaped, stalk-shaped, fat, squat, parallel, rectangle, bunches, pyramidSize great, little, large, small, tallColor brown, purple, red, gold, dark, yellow, silver, chocolate, green, orangesTouch Texture creased, frill, glass, sprigs, peeled, cut, stripped, grated, peppered, crustTaste peppered over with crust crumbs, a round of spiced beef, grated nutmeg, chocolates and sweets3.

Topic 2 ( also thesis ): On highways drivers should use the four-second rule, not the two-secondrule.1) The distance needed to stop a car should vary with the square of its speed.2) If the driver accelerates, the stopping distance needs to increase accordingly.Topic 3(also restatement): … use the two-second rule for city driving and the four-second rule for highways.1)Most the slowing occurs over the last half of the stopping distance.2)Some practical examples are given.3)For greater details the reader may refer to the attached table to determine the righttime allowed to avoid accidents.Sample EssaysOn Student Lovers’ Living Togethe r•According to official statistics, the number of college student lovers living together offcampus in Beijing has increased by four times between 1997 and 2001. This is undeniably true of many other places in China. Although many students do not strongly object to it, I don’t think it is advisable for college student lovers to live together away from campus.•Some lovers say that living together can relieve their loneliness and pressure, but it is notreally the best choice. On the one hand, the real reason for their loneliness is that they are not focusing their mind on study. Study, the most important task for university students, can prove to be fascinating if you really focus on it./ On the other hand, even if their loneliness is real, there are many better ways to deal with it./ For instance, they can find friends to take part in sports or other entertaining activities. By staying away from other classmates, living together can be a source of rather than solution to loneliness.•Other lovers argue that they mean to get married after graduation, and this experience can help them test each other to see if they are suitable for married life. But this mentality does not hold water. The two lovers may really love each other, but living together can actually spoil a good relationship, because it enters into weakness rather strength, doubt rather than conviction. / A follow-up study shows that few couples living together really end in marriage.Unit 164.Task One1) However 2) open 3) too 4) because 5) as a result6) Secondly 7) unless 8) even 9) prolong 10) delays 11) benefits5.1) Diseases are not caused by evil spirits but by other factors.2) The minor propositions are: causes of disease are congenital, infectious and nutritional.3) The main expository method is cause and effect.4) Use of pronouns: some, other;Use of adverbial phrase: as wellUse of synonyms: cause, lead to, giver rise to, result from。
