Unit OneMan has a blood tie with nature and nobody can live outside nature. Nature provides us with everything we need: the air we breathe, the water we drink, and the food we eat.For quite a long time after man began to live in the (1) realm of nature, he lived in fear of its destructive forces. He used to regard nature with its (2)elemental forces as something hostile to him. And even the forest was something wild and frightening to him. Very often, he was unable to (3) obtain the merest daily necessities though he worked together with others (4)stubbornly and collectively with his imperfect tools. Through his interaction with nature, man changed it gradually. He cut down forest, cultivated land, (5)transferred various species of plants and animals to different climatic conditions, changed the shape and climate of his environment and (6)transformed plants and animals. He (7)subdued and disciplined electricity and compelled it to serve the interests of society.Nonetheless, with the constant (8)expansion of agriculture and industry, man has robbed nature too much of its (9)irreplaceable resources, polluted his own living environment and caused about 95% of the species that have existed over the past 600 million years to become (10)extinct and still many others to be endangered. The previous (11)dynamic balance between man and nature is on the (12)verge of breaking down. Man is now faced with the problem of how to stop, or at least to (13) moderate the destructive effect of technology on nature. The crisis of the (14)ecological situation has become a global problem. The solution to the problem depends on (15)rational and wise organization both of production itself and care for Mother Nature. This can only be done by all humanity, rather than by individuals, enterprises or separate countries.Unit FouMost people have work to do. With work, they can (1) enjoy their lives. However, people who did (2)physical labor were looked down upon in the past. Many people were (3) compelled to take manual labour because it was an absolute (4) necessity for them to earn a living and to (5) support their families. By contrast, people who did (6) mental work were highly respected. Under the influence of this idea, even today some people still (7) idealize their funture when making choices for their career. What they care most about is whethere the job can give them enough social (8) status rather than whether they can realize their (9) values in it. In their eyes, those who do manual labor should still be (10) classifiedas inferior in social status.In fact, there is no (11) esential difference between those who work with their hands and those who work with their (12) mind . Whether a job is labor or work does not depend on the job itself but on people’s (13)attitude towards it. As long as you like your job, you will think you are (14) fortunate enough to take it and you will do it enthusiastically.Unit 5What does success mean to you? Does it mean wealth, fame, power or something else? Different people have different pursuits in life so they understand success in different ways. Some people (1) chase money their whole lives. To them, more money means more success. Some people run after fame. With fame and (2) reputation, they can gain the admiration and love of many others. However, some people (3) dedicate themselves to the well-being of society.Doubtlessly, money is something that can be used as a (4) reward to those who have done valuable work. Those who perform their work excellently should be paid (5)sufficiently. But success cannot be (6) measured in monetary terms, nor in terms of the amount of power one may exercise over others. After all, money and power can (7) assure people neither of happiness nor of respect from others.Fame, too, is a flawed measure of success. (8) Momentary fame can bring great joy to those who have it for a time. But they are very likely to become the slaves of their (9) celebrity because of the public’s demands. In addition, they will easily become the (10)target of everyone who disagrees with them and of the media as well. To be (11) frank, if one is unable to fully enjoy life and (12) liberty, the short-lived success is nothing but (13)illusory.Therefore, to achieve the right kind of success is vitally important. As long as one can combine his own material needs and spiritual satisfaction with those of the well-being of society, he should be held in high (14) regard.Unit SixTruth is a fact accepted as true, for which proof exists. Truth is a great principle, without which beauty may fade and love may (1) wither those who uphold truth have a strong (2) sense of responsibility. Those who hold firmly to truth are (3) faithful to their duty and the people they serve. They (4) commit themselves to the well-being of others. With (5) aspirations to make a contribution to society, they are ready to correct their own mistakes, if any. It can be said that they are men of moral integrity who never ask for (6) gratitude in return.Truth (7) dawns upon us slowly but surely. In the long quest for truth, people have (8) accumulated precious knowledge and experience. However, truth also needs (9) nourishment just as plants need water, because many people are too (10) preoccuped with petty and sometimes even mean concerns to respond to the great beauty of truth when it (11) flowers or they frequently fail to appreciate truth when it is (12) tendered.In short, truth is an invaluable asset to the whole of humanity. Stick to the truth and we will (13) weave a timeless pattern, and earn the respect and esteem of others, (14) elevate the world today above its present imperfections and place ourselves in the proud position of promoting the good of the humanity.Unit sevenWe often hear people say, "Time is money." But today many Americans have come to realize that the crazy pursuit of money is leaving them too little time to enjoy life. They are tired of working just for the (1) luxuries of life and are beginning to change their fast-paced lifestyles for a simple and (2) frugal one, hoping to keep family, friends, work and play all of a piece.For some people, creating a more balanced life involves changing jobs or locations. For others, it means (3) trading two incomes for one, in which case they must (4) curtail expenses. So some have sold out their (5) splendid homes and moved into smaller houses. They have given up the extra cars, unnecessary modern conveniences, and expensive (6) hobbies. They now do things by themselves to avoid paying for the services of others. They resist the temptation to purchase things on (7) impulse and spend money only on (8) bare necessities and things that do not make (9) wasteful use of the earth's resources.However, they do not (10) deny themselves what they like or enjoy. The change in their lifestyle is not one involving (11) deprivation; it is just simplification. They believe that they can still live a happy and fulfilling life on less money. Indeed, whether we can (12) naintain a healthy lifestyle or not does not depend on how wealthy we are but on whether we have the (13) resolve and courage to discard our old (14) consumption habits.Unit EightThe Story of an Hour leaves us much to think about. In the story, when Richards, who worked in the newspaper office, learned that his friend Brently Mallard had been killed in a railroad (1) disaster, he was greatly shocked. He only waited until he was a(2) assured by a second telegram and then he (3) hastened to go to Josephine, sister of Brently's wife, and asked her to break the news as (4) gently as possible to her sister because he knew Mrs. Mallard was (5) afflicted with a heart trouble. He was afraid that if someone less (6) tender brought the message to her ahead of him, there might be dreadful consequences.People usually expect a wife to accept such sad news with a (7) paralyzed inability, but Mrs. Mallard did not. At the news, she wept at once, with sudden, wild (8) abandonment in her sister's arms, and then she went to her own room, forbidding anyone else to go in.When she was alone, she felt something (9) subtle coming to her, which gradually came to her mind, beginning to (10) possess her. Hard as she tried, she couldn't get rid of the feeling. What was it? She didn't know. However, a clear and excited (11) perception occupied her which made her regard her husband's death no longer as something important, because beyond that bitter moment she saw a long (12) procession of years to come that would belong to her absolutely, during which her husband would not (13) impose his will upon her any more.Just at that moment, her husband came back, (14) travel-stained, carrying his briefcase and umbrella. Seeing him, she died of a sudden heart attack.。
