Later it was a fireman, policeman, lawyer . As I grew older my dreams of the future 42

21、 . When, at last, I was in college, I made up my 43 to become a preacher(牧师) as my father. 44 I studied and prepared for that life. I reached 45 in the end and I was preaching nearly fulltime for much of my adult life. However, for many, there is a “thief” which goes around stealing our 46 . Sometim

22、es, the thief will come as a parent, a relative, or a friend, but the 47 thief is, so many times, just 48 . We find ourselves just about reaching the top, and this “small” 49 inside says, “You will never make 50 .” “You cant possibly do this.” And on and on the “small” voice 51 some kind of failure.

23、 Failure, though, is exactly how dreams are 52 . It is one of the most important tools we have, because it teaches us invaluable 53 . And, when we learn these lessons well, we are ready 54 success. The message I always gave my children was that you 55 do anything your heart desires. Remember the say

24、ing, “Nothing is 56 to a willing heart.” There are 57 “overnight” successes, but with determination, it will come. Imagine yourself in the life you dream of 58 . Then in your heart, believe it 59 happen for you. Then work, work, work. You get the picture. So, be true to your dream, and dont let anyo

The family would eat together nightly at the dinner table. But the elderly grandfathers shaky hands and failing sight made eating r

29、ather difficult. Peas rolled off his spoon, dropping to the floor. When he grasped his glass of milk, it often spilled clumsily(笨拙地) at the tablecloth.With this happening almost every night, the son and daughter-in-law became annoyed with the mess.“We must do something about grandfather,” said the s

30、on.“Ive had enough of his milk spilling, noisy eating and food on the floor,” the daughter-in-law agreed.So the couple set a small table at the corner.There, grandfather ate alone while the rest of the family enjoyed their dinner at the dinner table. Since grandfather had broken a dish or two, his f

31、ood was served in wooden bowls. Sometimes when the family looked in grandfathers direction, he had tears in his eyes as he ate alone. Still, the only words the couple had for him were sharp warnings when he dropped a fork or spilled food. The four-year-old watched it all in silence.One evening, befo

32、re supper, the father noticed his son playing with wood pieces on the floor. He asked the child sweetly, “What are you making?” Just as sweetly, the boy replied, “Oh, Im making a little bowl for you and mama to eat your food from when I grow up.” The four-year-old smiled and went back to work.These

33、words so struck the parents that they were speechless. Then tears streamed down their cheeks. Though no words were spoken, both knew what must be done. 61.

36、s old saying? Joanne Gordon does. She is the author of Be Happy at work and other books about careers(职业). Gordon believes that about 30% of employees(雇员) in North America do not like their jobs, and she thinks that is terrible. She wants to help people who do not feel satisfied with their jobs find

37、 work that is good for them. Joanne says, “There are no happy jobs, only happy workers.” She believes that happy workers share three main characteristics.First, happy workers enjoy the daily activities of their jobs, and they look forward to the workday. Take Tony Hawk, for example. At age 14, he be

38、came a professional skateboarder. Now he is a businessman working on projects related to skateboardingfilms and video games, but he still skates every day. He once said, “My youngest sons pre-school was recently asked what their dads do for work. My son said, Ive never seen my dad do work.” Tony agr

39、ees that his job doesnt look like work. He has found a way to spend each day doing a job he enjoys.Second, happy workers like the people they work with. Sally Ayote says, “I work with the coolest people in the world.” She and her group cook for almost 1,200 people in Antarctica. Most of these people

40、 are scientists who are doing research. Sally loves to sit and talk with them. She says, “There is no television here, no radio, so I get to know the scientists and what theyre studying.” Sally thinks she has a great job, and the best part about it is the people.Third, happy workers know that their

41、work helps others. Caroline Barons work helps people who have had to leave their home countries because of war or other dangers. She is a filmmaker who started an organization called FilmAid, which shows movies in refugee(难民) camps around the world. Caroline believes that movies can be very helpful

42、in these camps. For one thing, entertaining movies let refugees forget their troubles for a little while. Movies can also teach important subjects like health and safety. For example, in one camp, thousands of refugees saw a movie about how to get clean water. Caroline knows that is helping other pe

43、ople, and this makes her feel proud and happy about her work.Tony Hawk, Sally Ayote, and Caroline Baron all get great satisfaction from their work. Tony Hawk says, “Find the thing you love. If you are doing what you love, there is much more happiness there than being rich or famous.” Joanne Gordon w

44、ould agree. She encourages people to find something they enjoy doing, find people they like to work with, and find ways to help others. Then they can be proud of what they do, and they will probably be happy at work.64. Who is the book, Be Happy at Work, written for? A. Joanne Gordon herself. B. Ton

45、y Hawk, Sally Ayote, and Caroline Baron.C. People who do not feel satisfied with their jobs. D. The workers who agree with the authors ideas.65. Why did Tony Hawks son say, “Ive never seen my dad do work.”?A. Because Tony Hawks job doesnt look like work.B. Because Tony Hawk always finds something en

46、joyable in his job.C. Because Tony helps people forget their troubles while skating.D. Because the best part about his job is to spend each day skating.66. Tony Hawk, Sally Ayote, and Caroline Baron are good examples that show us _. A. how to be a successful businessman B. how to help people in diff

47、icultiesC. how to get along with the coolest people D. how to become a happy worker67. Which of the following is NOT true according to the passage? A. Some people believe that only a few kinds of jobs can really make people feel happy. B. The writer of the passage tells us that many different kinds

48、of work can be enjoyable. C. The author of Be Happy at Work thinks that happiness at work is really important.D.

61、tEUsing too much water or throwing rubbish into our rivers are clear ways that humans can put our water supply in danger, but we also affect our water supply in less obvious ways. You may wonder how paving(铺砌) a road can lead to less useable fresh water. A major part of the water we use every day is

62、 groundwater. Groundwater does not come from lakes or rivers. It comes from underground. The more roads and parking lots we pave, the less water can flow into the ground to become groundwater. Human activity is not responsible for all water shortages. Drier climates are of course more likely to have

63、 droughts(干旱) than areas with more rainfall, but in any case, good management can help to make sure there is enough water to meet our basic needs .

65、leaks in your home. You can even help to keep our water supply clean by recycling batteries instead of throwing them away.77. Which of the following is most likely to lead to less groundwater?A. Using river water. B. Throwing batteries away.C. Paving parking lots. D. Throwing rubbish into lakes.78.

66、What can be inferred from the text?A. All water shortages are due to human behavior.B. It takes a lot of effort to meet our water needs.C. There is much we can do to reduce family size.D. The average family in America makes proper use of water.79. The last paragraph is intended to .A. show us how to

67、 fix leaks at home B. tell us how to run a dishwasher C. prove what drinking glass is best for us D. suggest what we do to save water at home 80. The text is mainly about .A. how human activity affects our water supplyB. how much we depend on water to live C. why droughts occur more in dry climatesD
