1、Unit 1When I think of people in this world who have really made a difference, I think of my parents. They were truly saints among ordinary people.I was one of the ten children my parents adopted. They rescued each of us from a life of poverty and loneliness. They were hardly able to restrain themsel

2、ves from bringing home more children to care for. If they had had the resources they certainly would have.Most people do not realize how much they appreciate someone until they pass away. My sisters and brothers and I did not want this to happen before we uttered（发出,讲出）the words “Thank you to our pa

3、rents.Although we have all grown up and scattered about the country, we got back together to thank our parents. My brother Tom undertook the task of organizing the event. Every Friday night, Mom and Dad have had the ham dinner special at the same restaurant for the last twenty years. That is where w

4、e waited without their knowing. When we first caught a glimose of them coming across the street, we all hide underneath a big table. When they entered, we leapt out and shouted, Thank you, Mom and Dad. My brother Tom presented them with a card and we all hugged. My Dad pretended that he had known we

5、 were under the table all along.Unit 2Women who exercise regularly need to be careful with what they eat. Researchers have found evidence that even moderate exercise can result in losing iron. They said that women who exercise regularly, especially in endurance activities, typically lose iron. In or

6、der to prevent this from becoming a problem, it is important that those women consume more meat or take supplements to replace the iron lost. Those who do not bother to get plentiful amounts of iron may begin to feel weak and tired. If you can get the recommended daily allowance of iron in your diet

7、, you will probably perform better, said one diet specialist. One shortcoming of taking iron pills is that the pill form is not well absorbed and can sometimes make you sick. It is preferable that you try to remedy the deficiency by getting more iron-rich meats in your diet.There are ways to help yo

8、ur body store away the iron it takes in. By getting plenty of Vitamin C, your body is able to process, or use, the iron better. Researchers acknowledge that everyones body is different and the problem will be less serious for some. Because it is impossible to decide whether or not this could be a pr

9、oblem for you, health specialists say it is advisable to check your iron levels. Even when you cant feel it, you may still have a problem.Unit 3While many private schools are focusing more on values, public schools are moving toward testing standards. The national government demands academic success

10、 and tests are taken as a key measurement for a schools performance. Schools with low test scores face penalties such as a reduction in money to run their schools. And, even individual teachers are being graded on how theyre preparing their students for these tests.We have concentrated too much on t

11、eaching the kids how to take these tests, commented one elementary school teacher. We should be providing a more comorehensive curriculum to these kids. We should be cultivating leadership and curiosity. Unfortunately, there is never time.One school principal remarked, Mlts true that it would be ben

12、eficial to our kids if they were getting better scores on the subjects being tested. The trouble is that in poorer areas of the city like ours, kids start school less eauipped to perform well. We have many obstacles to overcome before we can teach them basic subjects. All schools are not alike, so t

13、hey shouldnt be tested that way.The goal is to improve performance in schools that are not providing their students with tools for success, said one government official. He admits, however, that he is having a hard time convincing faculty and teachers this plan will work.Unit 4For many, beauty and f

14、ashion are permanently linked. With regard to fashion, the Barbie doll has been consistently in style. From the first Barbie dolls, Mattel took care to dress them in detailed, fashionable clothes. Some observers note that the fashions of the Barbie doll trace fashion trends perfectly since 1959. Whi

15、le critics complain that the models do not represent “average female bodies, they also complain about the Barbie dolls size. Some have criticized the dimensions (尺、J ) of the Barbie doll as an unattainable ideal of the female shape.Charlotte Johnson, the Barbie dolls first dress designer, explained

16、that the doll was not intended to reflect a female figure realistically, but rather to portray a(n) exaggerated shape underneath fashionable clothes. However, the unrealistic dimensions of the doll have brought the strongest criticism regarding the dolls encouragement of an obsession with weight and

17、 looks.Convinced of the negative effects of the Barbie doll on children, Cathy Meredig of High Self Esteem Toys developed a more realistically proportioned doll in 1991. Her doll did not sell well, however.Throughout the years, the Barbie doll has had several competitors but none have been able to c

18、ompete with the glamour offered by the Barbie doll.U 5As a surgeon, I have seen a lot of deaths. I am rarely astonished by anything. The other day , however ,one humorous and slightly odd story I heard touched me. A doctor told me that a very old woman he was dead , but when he was treating was lyin

19、g motionless on her pillow face down. He thought she was dead ,but when he approached he noticed she was breathing. Her hospital gown exposed her back bare, so he put a cover over her. Just then she sat up slowly, startling the doctor. She seemed quite alive.“I thought you were nearly gone,* the doc

20、tor said . “Your breathing was so shallow and you seemed lifeless. “Never mind that , doctor, l*ve been waiting for you, the old woman said quite confidently as if she were his mother. She had been a good mother to four, but she had survived them all. She gracefully handed the doctor a jab of sample

21、d a little and told he it was deliciours.“Good,“ she said ,handing him a piece of paper with writing. *This is how to make it He understood what a(n) privilege she had given him and took it with thanks and then left. The old woman lay back down and died soon after his departure Unit 6Do you know Feb

22、ruary 2nd is Groundhogs Day (土拨鼠日)？ Legend has it that on this morning, if a groundhog can see its shadow, there will be six more weeks of winter. If it cannot see its shadow, spring is on the way. Some believe that the means of forecast is rather arbitrary and is often incorrect. Others argue that

23、it is significant because it recognizes that the different parts of nature are connected in some way. Each part is dependent on the rest of the parts for a healthy system. Some farmers pay close attention to the behavior of ducks and geese when Dredictinq the weather. It is sensible to guess an earl

24、y winter is coming when you see ducks and geese moving south in October. Many dog owners can tell when winter or spring will come by stroking their pet. In preparation for winter, a dogs hair becomes thicker. Dogs lose hair as spring sets in.Information gathered from nature can help people to take p

25、recautions against a hard winter or bad storm. Some animals are even believed to be able to detect when an earthquake will occur. People holding this belief even go further to say that information gathered by computers is often worthless and nature is far more accurate: Isnt it time we started payin

26、g attention to what is around us?Unit 7Bill Gates is known around the world for the founding of Microsoft. And, most people are quite aware that his evolution from computer hacker to the worlds richest man was due in large part to his partner Paul Allen. But, while Gates fame has mushroomed since th

27、e beginning of Microsoft, Allen has remained less famous. Many around the world have followed the life of Gates, but are ignorant of what has happened to Allen. In fact, as most in the Northwest can tell you, Allen has made quite a(n) impact on the region and the world. In 2000, he retired from Micr

28、osoft, but the company retains him as a permanent advisor to top executives. Not all of Allens interests involve commercial success. Allen has given four hundred million dollars in charity to the University of Washington for science and technology research. He created the Experience Music Project in

29、 Seattle, employing famous architect Frank Gehry to design the building. This is not his only contribution to the arts. Allen is very involved with modernizing Hollywoods movie technology. His film studio is the most advanced in the world. He has also built a sports empire, buying both a basketball

30、and a football team as well as helping to support a local stadium, and he owns a sports magazine. Oh, and lets not forget, Allen is the seventh richest man in the entire world. Not bad.Unit 8You have probably heard of Dolly. She is the worlds first cloned sheep and quite famous. You would never know

31、 that she was such a famous animal just by looking at her, though. Shes about as unremarkable-looking as any sheep there ever was, commented one scientist who tends to the famous sheep.Now that Dolly has successfully been cloned, there are many scientists observing her every movement. Their hope is

32、that they never detect anything remarkable with Dolly. One of the scientists humorously remarked, Its quite a(n) boring job always sitting around hoping nothing will actually happen. But thats what they have essentially done. They hope that any differences between Dolly and the sheep she was copied

33、from are so minor that they go unnoticed.We dont want Dolly to live longer or jump higher. Some say that we are deliberately trying to create animals with remarkable qualities. This is not true. We simply are showing that we can make a（n） identical copy of the original safely and that the sheep is n

34、ormal.Despite the protests of the scientists working on the project, the debate over whether cloning is safe goes on. The US congress organized a national commission to study the legal and moral implications of cloning. Many would like to abolish all research on cloning. And while everyone argues, t

35、he scientists are simply continuing to watch Dolly.Unit 9My friend, Anna, said to me before I married Mike, Hes fine now, but wait until after youve married him. She thought that her own experience with marriage was aDDlicable to mine. Without even being asked, she cited all of the problems shes had

36、 with her husband. The disputes ranged from him not sharing responsibility for household tasks to how often he went out at night. And every time, Anna complained, her husband would find justification for what he did. If I were you, she advised, Id get everything documented in writing. If there is so

37、mething desirable about him now, make sure you get an agreement from him that he will continue it a代er you are married. I tried to dispose （处理掉,丢掉）of her advice saying that I thought Mike and I could handle it without such an agreement. She just dismissed （驳回） what I had to say with laughter. You ca

38、nt believe him just because what he said. Once you marry him, hell think he owns you, and everything will change, she said.I tried to ignore her advice, but the next day I changed my mind and talked to Mike. Mike, I said, Im not going to marry you unless you promise to always stay the same. He repli

39、ed, Youve been talking to Anna again, havent you?Unite 1Although they may not be the worlds fastest or strongest athletes, the 1830 competitions in the 2005 Special Olympics World Winter Games held in Nagano, Japan competed with all their hearts. At the closing ceremony Princess Takamado of Japan ma

40、de a speech .She said, The past week was all about smiles, gentleness and peace. I truly hope within my heart that the entire world can learn something here. We can all learn from the examples these special athletes have shown us.,The aim of the Special Olympics is clear. It is to encourage individu

41、als with intellectual disabilities to become physically fit. They are also encouraged to be productive and respected members of society through sports training and competition. If an athlete wins in competition, it is a bonus. However, in a way everyone wins. Lily Kuhn , 12, a skier with Team USA, c

42、ould hardly restrain her enthusiasm as the wrote home. She told her parents: I was proud of myself. I am happy not simply for winning, but fbr winning honestly, loving to compete and working the hardest for the longest time.The festival ending the games is something to remember. It isnt complete wit

43、hout the hugs. One event volunteer while hugging and handing out sweatshirts to some of the athletes held up his thumbs and said, All of these athletes are super! I cant go anywhere around here without getting a hug. I pray for more of this sort of thing. I hope that the spirit with which they have

44、competed might touch the whole world. Watching these young people blossom over the past week has truly touched my life.”At the end of the festival, the vice mayor for the city of Shanghai, which will host the 2007 summer games, accepted the flag for the Special Olympics pledging that “the city of Sh

45、anghai would open its arms to the world and to the Special Olympics”.Unite 2Jim Fixx had been a heavy smoker and weighed 214 pounds when he took up running in the 1960s. He soon reaped the benefits from running. His weight decreased by 60 pounds by the time his book, The Complete Book Of Running, wa

46、s published. His book inspired millions of people. In his book and on television talk shows, he extolled the benefits of physical exercise and how it considerably increased the average peoples life expectancy. His readers and audience became more health-conscious. However , to their shock, Fixx died

47、 at the age of 52 after his daily run. Many who opposed his beliefs said this was evidence that running was harmful. However, his supporters revealed that the real cause of Fixxs death was a heart attack. He came from a family where men had poor health stories. His father suffered a heart attack at

48、the age of 35 and died of one at 42. Given Fixxs unhealthy lifestyle until he took up running, many argued that running added many years to his life.Running does have its shortcomings, Acknowledges heart specialist Paul Thomas, in a recent medical journal. The impact can be hard on your knees. Runne

49、rs are more at risk during their training, particularly if they run marathons. However, the news for runners isnt all bad. Evidence suggests in spite of its shortcomings, moderate amount of running exercise can actually result in a longer, improved life.Dr. Dale Macdonald, a certified Strength and Conditioning specialist once summed up a discussion by saying, As with all athletic endeavors, running comes with both great reward
