I. 完形填空My mother seemed to be able to make dolls out of anything. She made some dolls for me and my two elder sisters. I 1 playing with them, but still, secretly, I hoped for a store-bought 2 like the one our rich cousin had. Her doll 3 open and close its blue glass eyes and even say "Mamma". I 4 stopped admiring it and hoping to have one.However, my dream 5 came true when I was six. One day my father came back from his business trip with three 6 dolls! They were much smaller than our cousin’s doll and their eyes were just painted ones, but I did not 7 such differences. They were 8 "store-bought"dolls. We each chose one and I named 9 Misako.Soon my sisters and I became devoted 10 . Our "children" kept us 11 all day. We gave them a bath, 12 them, brushed their hair, took them out for a walk and put them to bed. Several months later, they got more like real children — their 13 and bodies became dirtier;their dresses got stained; their hair less smooth.But, by then, 14 interests seemed to have moved into 15 toys.Their dolls were abandoned and in bad condition. One had 16 one of her arms, and 17 was one-legged. "You can 18 them if you want," my sisters said to me. Thus, I had 19 dolls. They were more or less handicapped (残疾) and they often looked at me as if they needed me to 20 them. I enjoyed this feeling of being needed — being theonly one in the world who could protect them with a lot of love. Indeed,they made the rest of my childhood days very happy.1.

He was, as he put it, “not very bright” and couldn’t win the attention of his very wealthy parents, who pref erred his “clever” older brother. At age 8, Horowitz was sent away to an abusive boarding school in his native England, even though he screamed and pleaded(恳求) with his parents year after year not to send him. “The thought was, ‘It’ll be good for him,’” he recalled.It was not. Horowitz did badly in his studies, had few friends and was bullied for five years. “My teachers couldn't have had a lower opinion of me,” he said. “I wasn't even smart enough to rebel. The one thing I remember from the very earliest age was this desire to write. When I was 10 years old, I remember asking my parents to get me a typewriter for my birthday because I wanted to be a writer.”Now, at age of 55, Horowitz is one of the world's most successful children's book authors. His Alex Rider series has sold more than 5 million copies, and the eighth book featuring the young spy, Crocodile Tears, came out this month.The Alex Rider books tell the adventures of 14-year-old Alex Rider, anagent for the British intelligence agency M16.Horowitz said he doesn't try to write for kids; it just es out that way. “I have a feeling it's to do with purity and simplicity. I give as little information as is necessary to describe the room, the character in the room, and get on with the action,” he s aid.The style has also made Horowitz a successful writer of television shows for adults in Britain because, he says, writing books for kids is a lot like writing television for grown-ups: In both cases, it's all about entertaining people with a good story.Now, Horowitz couldn't be happier with his life. He sums up his success: “…you can be anything you want to be if you just believe in yourself.I do believe it pletely.”56. In the boarding school, Horowitz’s teachers ________.A. thought little about his abilityB. showed great concern for himC. taught him how to write storiesD. often criticized him57. Which of the following is true of Anthony Horowitz?A. He was the beloved child of his family.B. He benefited a lot from boarding school.C. He emphasizes the plot rather than characters in stories.D. Although he is successful, he isn’t very happy.58. What advice does Horowitz have for readers?A. Interest is the best teacher.B. Hardship teaches valuable lessons.C. Confidence is the key to success.D. Industry is the parent of success.59. In which section can you most probably read the passage?A. Campus TrendsB. Culture & LeisureC. Our WorldD. Science LifeBMini Book Excerpts（节选）BiographyWhen Salinger learned that a car park was to be built on the land, the middle-aged writer was shocked and quickly bought the neighboring area to protect it… The townspeople never forgot the rescue and came to help their most famous neighbor.J. D. Salinger：A Life by Kenneth Slawenski（Random House,$27）Mystery“You’re a smart boy. Benny’s death was no accident, and you’re the only one who saw it happen. Do you think the murderer should get away with it ? ” The boy was staring stubbornly (固执地；倔强地) at his lap again.A thought suddenly occurred to Annika, “Did you …You recognized the man in the car, didn’t you?”The boy hesitated, twisting his fingers, “Maybe,” he said quietly.Red Wolf by Liza Marklund（Atria Books, $25. 99）Short StoriesShe wants to say to him what she has learned, none of it in class: Somewomen are born stupid, and some women are too smart for their own good. Some women are born to give , and some women only know how to take. Some women learn who they want to be from their mothers, some who they don’t want to be. Some mothers suffer so their daughters won’t. Some mothers love so their daughters won’t.You Are Free by Danzy Senna（Riverhead Books,$15）HumorDo your kids like to have fun? e to Fun Times! Do you like to watch your kids having fun? Bring them to Fun Times! Fun Times!’s “amusement cycling” is the most fun you can have, legally, in the United States right now. Why spend thousands of dollars flying to Disney World when you can spend less than half of that within a day’s drive of most cities?Happy: And Other Bad Thoughts by Larry Doyle （Ecco,$14. 99）60. If the readers want to know about the life of Salinger, they should buy the book published by ________.A. EccoB. Random HouseC.Riverhead Books D. Atria Books61. The book Happy :And Other Bad Thoughts is intended for ________.A. young childrenB. Disney World workersC. middle school teachersD. parents with young children62. Which book describes women with characters of their own?A. You Are FreeB. J. D. Salinger: A LifeC. Happy: And Other Bad ThoughtsD. Red Wolf63. After finishing the book Red Wolf, the readers would learn that ________.A. the murderer got away with the crimeB. Benny died of an accidentC. the boy helped arrest the murdererD. Annika carried out the crimeCI must have been about fourteen then, and I put away the incident from my mind with the easy carelessness of youth. But the words, Carl Walter spoke that day, came back to me years later, and ever since have been of great value to me.Carl Walter was my piano teacher. During one of my lessons he asked how much practicing I was doing. I said three or four hours a day."Do you practice in long stretches, an hour at a time?""I try to.""Well, don't," he exclaimed. "When you grow up, time won't e in long stretches. Practice in minutes, whenever you can find them five or ten before school, after lunch, between household tasks. Spread the practice through the day, and piano-playing will bee a part of your life."When I was teaching at Columbia, I wanted to write, but class periods, theme-reading, and mittee meetings filled my days and evenings. For two years I got practically nothing down on paper, and my excuse was that I had no time. Then I remembered what Carl Walter had said. During the nextweek I conducted an experiment. Whenever I had five minutes unoccupied, I sat down and wrote a hundred words or so. To my astonishment, at the end of the week I had a rather large manuscript ready for revision, later on I wrote novels by the same piecemeal method. Though my teaching schedule had bee heavier than ever, in every day there were idle moments which could be caught and put to use. I even took up piano—playing again, finding that the small intervals of the day provided sufficient time for both writing and piano practice.There is an important trick in this time—using formula: you must get into your work quickly. If you have but five minutes for writing, you can't afford to waste four chewing your pencil. You must make your mental preparations beforehand, and concentrate on your task almost instantly when the time es. Fortunately, rapid concentration is easier than most of us realize.I admit I have never learnt how to let go easily at the end of the fiveor ten minutes. But life can be counted on to supply interruptions. Carl Walter has had a tremendous influence on my life. To him I owe the discovery that even very short periods of time add up to all useful hoursI need, if I plunge（投入）in without delay.64. The meaning of “stretch” in the underlined part is the same as that in sentence “________”.A. Bob worked as a government official for a stretch of over twenty years.B. The forests in the north of the province stretch for hundreds of miles.C. My family wasn’t wealthy by any stretch of the imagination.D. During his senior year his earnings far enough to buy an old car.65. We can infer that the writer ________.A. has new books published each year however busy his teaching isB. is always tired of interruptions in life because his teaching scheduleis always heavyC. has formed a bad habit of chewing a pencil while writing his novelsD. can find sufficient time for mental preparations beforehand, so he'sdevoted to work instantly66. What is the best title of this passage?A. Concentrate on Your WorkB. A Little at aTimeC. How I Became a WriterD. Good Advice Is Most ValuableDThe interview is an important event in the job-hunting process, because the 20 or 30 minutes you spend with the interviewer may decide whether or not you get the particular job you want. Therefore, it is important to remember that your purpose during the interview may differ from that of the potential employer. You want to make yourself stand out as a whole person who has personal strengths and should be considered the right person for the job. It is encouraging to know that the interviewer’s task is not to embarrass you, but to hire the right person for the job.Remember, job-hunting is very petitive. Anything you can do to improveyour interview techniques will be to your advantage. The following suggestions may help you land the most important job.Your goal in this interview is to make sure your good points get across. The interviewer won’t know them unless you point them out, so try to do this in a factual and sincere manner.Don’t say anything bad about your former employers. If you have been fired from a job and the interview asks about it, be honest.Show the interviewer that you are interested in the pany by asking questions. Ask about responsibilities, working conditions, promotion opportunities and benefits of the job you are interviewing for.If at some point you decide the interview is not going well, do not let your discouragement show. You have nothing to lose by continuing a showof confidence, and you many have much to gain. It may be real, or it maybe a test to see how you react to adverse conditions.Some interviewers may bring up salary early in the interview. At this time, you may indicate that you are more interested in a job where you can prove yourself than a specific salary. This politely passes the question back to the interviewer. If possible, you should negotiate for salary after you have been offered a job and have pleted the paperwork.67. To get the job you want, during the interview you should ________.A. avoid the interviewer’s questions that are designed to embarrass youB. remember that you are the bestC. make yourself stand out as the right person for the jobD. tell yourself that you want to get the job68. If you did not get along with your former employer, you ________.A. should tell a lie to the interviewerB. should not speak ill of himC. should refer to him in a factual mannerD. should never mention it69. The underlined word “adverse” in the sixth paragraph can be replaced by ________.A. difficultB. friendlyC. oppositeD. different70. The passage is mainly about ________.A. how to make your strengths understoodB. how to show your interest in the jobC. how to be frank and sincereD. how to deal with an interviewIV. 任务型阅读Of the hundreds of self-change techniques that have been suggested over the centuries, perhaps only a dozen are totally different. Researchers have tried to see which ones work best.Three techniques deserve special mention: they’re powerful, simple and easy to learn.What’s more, individuals who have made successful changes in their lives—changes in eating habits, career paths, coping strategies, and so on—often rely on one or more of the three techniques.To get yourself started in a new direction, try the Three M’s:Modify your environmentPeople who have never tried this are astonished by the enormous effect it often has. I’ve known several people who have overe nail-biting simply by buying 50 nail files and distributing them everywhere: in their pockets, their desks and their bedrooms. With a nail file always within reach, they tended to groom rather than bite. To change yourself, change your world.Monitor your behaviorI’ve been reading research studies on self-monitoring for 20 years, and I’ve conducted some myself. The fact is, if you monitor what you do, you’ll probably do better.A study by Canadian researchers showed that teenagers arrived more promptly at a swim practice when they were given an attendance sheet to record their arrival times. Sonya Carr and Rebecca Punzo reported that self-monitoring improves academic performance of emotionally disturbed children in reading, mathematics and spelling. Dozens of studies have similar results, all inspired by heightening our awareness of our behavior.Make mitmentsWhen you mit yourself to another person, you establish a possibility of reinforcement (后效强化)；you’ve automatically arranged for a reward if you stick to it and a punishment if you don’t. It puts some pressure on you, and that’s often just what you need.For instance, if you want to exercise more, arrange to do it with a friend. If you don’t show up, your friend will get angry, and that may be just the ticket to keeping you punctual(准时的). In 1994 Dana Putnam and other researchers showed that patients who made written mitments were far morelikely to take prescribed medicine than patients who hadn’t.There’s good news here for all of us. We can meet many of the demands and overe many of the challenges of life with simple skills that anyone can master an d that don’t require willpower---in other words, with skill, not will.Change your bad habits to goodParagraphoutlineSupporting detailsIntroduction[·Most of self-change techniques that have beensuggested before are ( 71 )________.·People who are ( 72 ) ________in making changes intheir lives often rely on one or more of the Three M’s.Modify your ( 73 ) ________·Those who have never tried this method can( 74 ) ________enormously from it.·Several people have overe nail-biting with a nail file always( 75 ) ________reach.(76)________your behavior ·If you monitor what you do, you are very( 77 )________to do better.·The more you bee( 78 ) ________of what you’re doing, the better you will perform.Make mitments·mitting yourself to someone else will pressure you tocarry it out, which helps reward yourself.·The patients who made written mitmentsprobably( 79 )________medicine as instructed by doctors.Conclusion Anyone can satisfy most of his demands and overe mostof the challenges with simple skills(80 ) ________ thangreat willpower.V. 单词拼写81.

I 1 playing with them, but still, secretly, I hoped for a store-bought 2 like the one our rich cousin had. Her doll 3 open and close its blue glass eyes and even say "Mamma". I 4 stopped admiring it and hoping to have one.However, my dream 5 came true when I was six. One day my father came back from his business trip with three 6 dolls! They were much smaller than our cousin’s doll and their eyes were just painted ones, but I did not 7 such differences. They were 8 "store-bought"dolls. We each chose one and I named 9 Misako.Soon my sisters and I became devoted 10 . Our "children" kept us 11 all day. We gave them a bath, 12 them, brushed their hair, took them out for a walk and put them to bed. Several months later, they got more like real children — their 13 and bodies became dirtier;their dresses got stained; their hair less smooth.But, by then, 14 interests seemed to have moved into 15 toys.Their dolls were abandoned and in bad condition. One had 16 one of her arms, and 17 was one-legged. "You can 18 them if you want," my sisters said to me. Thus, I had 19 dolls. They were more or less handicapped (残疾) and they often looked at me as if they needed me to 20 them. I enjoyed this feeling of being needed — being theonly one in the world who could protect them with a lot of love. Indeed,they made the rest of my childhood days very happy.1.

He was, as he put it, “not very bright” and couldn’t win the attention of his very wealthy parents, who pr eferred his “clever” older brother. At age 8, Horowitz was sent away to an abusive boarding school in his native England, even though he screamed and pleaded(恳求) with his parents year after year not to send him. “The thought was, ‘It’ll be good for him,’” he recalled.It was not. Horowitz did badly in his studies, had few friends and was bullied for five years. “My teachers couldn't have had a lower opinion of me,” he said. “I wasn't even smart enough to rebel. The one thing I remember from the very earliest age was this desire to write. When I was 10 years old, I remember asking my parents to get me a typewriter for my birthday because I wanted to be a writer.”Now, at age of 55, Horowitz is one of the world's most successful children's book authors. His Alex Rider series has sold more than 5 million copies, and the eighth book featuring the young spy, Crocodile Tears, came out this month.The Alex Rider books tell the adventures of 14-year-old Alex Rider, anagent for the British intelligence agency M16.Horowitz said he doesn't try to write for kids; it just es out that way. “I have a feeling it's to do with purity and simplicity. I give as little information as is necessary to describe the room, the character in the room, and get on with the action,” he said.The style has also made Horowitz a successful writer of television shows for adults in Britain because, he says, writing books for kids is a lot like writing television for grown-ups: In both cases, it's all about entertaining people with a good story.Now, Horowitz couldn't be happier with his life. He sums up his success: “…you can be anything you want to be if you just believe in yourself.I do believe it pletely.”56. In the boarding school, Horowitz’s teachers ________.A. thought little about his abilityB. showed great concern for himC. taught him how to write storiesD. often criticized him57. Which of the following is true of Anthony Horowitz?A. He was the beloved child of his family.B. He benefited a lot from boarding school.C. He emphasizes the plot rather than characters in stories.D. Although he is successful, he isn’t very happy.58. What advice does Horowitz have for readers?A. Interest is the best teacher.B. Hardship teaches valuable lessons.C. Confidence is the key to success.D. Industry is the parent of success.59. In which section can you most probably read the passage?A. Campus TrendsB. Culture & LeisureC. Our WorldD. Science LifeBMini Book Excerpts（节选）BiographyWhen Salinger learned that a car park was to be built on the land, the middle-aged writer was shocked and quickly bought the neighboring area to protect it… The townspeople never forgot the rescue and came to help their most famous neighbor. J. D. Salinger：A Life by Kenneth Slawenski（Random House,$27）Mystery“You’re a smart boy. Benny’s death was no accident, and you’re the only one who saw it happen. Do you think the murderer should get away with it ? ” The boy was staring stubbornly (固执地；倔强地) at his lap again.A thought suddenly occurred to Annika, “Did you …You recognized the man in the car, didn’t you?”The boy hesitated, twisting his fingers, “Maybe,” he said quietly.Red Wolf by Liza Marklund（Atria Books, $25. 99）Short StoriesShe wants to say to him what she has learned, none of it in class: Somewomen are born stupid, and some women are too smart for their own good. Some women are born to give , and some women only know how to take. Some wome n learn who they want to be from their mothers, some who they don’t want to be. Some mothers suffer so their daughters won’t. Some mothers love so their daughters won’t.You Are Free by Danzy Senna（Riverhead Books,$15）HumorDo your kids like to have fun? e to Fun Times! Do you like to watch your kids having fun? Bring them to Fun Times! Fun Times!’s “amusement cycling” is the most fun you can have, legally, in the United States right now. Why spend thousands of dollars flying to Disney World when you can spend less than half of that within a day’s drive of most cities?Happy: And Other Bad Thoughts by Larry Doyle （Ecco,$14. 99）60. If the readers want to know about the life of Salinger, they should buy the book published by ________.A. EccoB. Random HouseC.Riverhead Books D. Atria Books61. The book Happy :And Other Bad Thoughts is intended for ________.A. young childrenB. Disney World workersC. middle school teachersD. parents with young children62. Which book describes women with characters of their own?A. You Are FreeB. J. D. Salinger: A LifeC. Happy: And Other Bad ThoughtsD. Red Wolf63. After finishing the book Red Wolf, the readers would learn that ________.A. the murderer got away with the crimeB. Benny died of an accidentC. the boy helped arrest the murdererD. Annika carried out the crimeCI must have been about fourteen then, and I put away the incident from my mind with the easy carelessness of youth. But the words, Carl Walter spoke that day, came back to me years later, and ever since have been of great value to me.Carl Walter was my piano teacher. During one of my lessons he asked how much practicing I was doing. I said three or four hours a day."Do you practice in long stretches, an hour at a time?""I try to.""Well, don't," he exclaimed. "When you grow up, time won't e in long stretches. Practice in minutes, whenever you can find them five or ten before school, after lunch, between household tasks. Spread the practice through the day, and piano-playing will bee a part of your life."When I was teaching at Columbia, I wanted to write, but class periods, theme-reading, and mittee meetings filled my days and evenings. For two years I got practically nothing down on paper, and my excuse was that I had no time. Then I remembered what Carl Walter had said. During the nextweek I conducted an experiment. Whenever I had five minutes unoccupied, I sat down and wrote a hundred words or so. To my astonishment, at the end of the week I had a rather large manuscript ready for revision, later on I wrote novels by the same piecemeal method. Though my teaching schedule had bee heavier than ever, in every day there were idle moments which could be caught and put to use. I even took up piano—playing again, finding that the small intervals of the day provided sufficient time for both writing and piano practice.There is an important trick in this time—using formula: you must get into your work quickly. If you have but five minutes forwriting, you can't afford to waste four chewing your pencil. You must make your mental preparations beforehand, and concentrate on your task almost instantly when the time es. Fortunately, rapid concentration is easier than most of us realize.I admit I have never learnt how to let go easily at the end of the fiveor ten minutes. But life can be counted on to supply interruptions. Carl Walter has had a tremendous influence on my life. To him I owe the discovery that even very short periods of time add up to all useful hoursI need, if I plunge（投⼊）in without delay.64. The meaning of “stretch” in the underlined part is the same as that in sentence “________”.A. Bob worked as a government official for a stretch of over twenty years.B. The forests in the north of the province stretch for hundreds of miles.C. My family wasn’t wealthy by any stretch of the imagination.D. During his senior year his earnings far enough to buy an old car.65. We can infer that the writer ________.A. has new books published each year however busy his teaching isB. is always tired of interruptions in life because his teaching scheduleis always heavyC. has formed a bad habit of chewing a pencil while writing his novelsD. can find sufficient time for mental preparations beforehand, so he'sdevoted to work instantly66. What is the best title of this passage?A. Concentrate on Your WorkB. A Little at aTimeC. How I Became a WriterD. Good Advice Is Most ValuableDThe interview is an important event in the job-hunting process, because the 20 or 30 minutes you spend with the interviewer may decide whether or not you get the particular job you want. Therefore, it is important to remember that your purpose during the interview may differ from that of the potential employer. You want to make yourself stand out as a whole person who has personal strengths and should be considered the right person for the job. It is encouraging to know that the interviewer’s task is not to embarrass you, but to hire the right person for the job.Remember, job-hunting is very petitive. Anything you can do to improveyour interview techniques will be to your advantage. The following suggestions may help you land the most important job. Your goal in this interview is to make sure your good points get across. The interviewer won’t know them unless you point them out, so try to do this in a factual and sincere manner.Do n’t say anything bad about your former employers. If you have been fired from a job and the interview asks about it, be honest.Show the interviewer that you are interested in the pany by asking questions. Ask about responsibilities, working conditions, promotion opportunities and benefits of the job you are interviewing for.If at some point you decide the interview is not going well, do not let your discouragement show. You have nothing to lose by continuing a showof confidence, and you many have much to gain. It may be real, or it maybe a test to see how you react to adverse conditions.Some interviewers may bring up salary early in the interview. At this time, you may indicate that you are more interested in a job where you can prove yourself than a specific salary. This politely passes the question back to the interviewer. If possible, you should negotiate for salary after you have been offered a job and have pleted the paperwork.67. To get the job you want, during the interview you should ________.A. avoid the interviewer’s questions that are designed to embarrass youB. remember that you are the bestC. make yourself stand out as the right person for the jobD. tell yourself that you want to get the job68. If you did not get along with your former employer, you ________.A. should tell a lie to the interviewerB. should not speak ill of himC. should refer to him in a factual mannerD. should never mention it69. The underlined word “adverse” in the sixth paragra ph can be replaced by ________.A. difficultB. friendlyC. oppositeD. different70. The passage is mainly about ________.A. how to make your strengths understoodB. how to show your interest in the jobC. how to be frank and sincereD. how to deal with an interviewIV. 任务型阅读Of the hundreds of self-change techniques that have been suggested over the centuries, perhaps only a dozen are totally different. Researchers have tried to see which ones work best.Three technique s deserve special mention: they’re powerful, simple and easy to learn.What’s more, individuals who have made successful changes in their lives—changes in eating habits, career paths, coping strategies, and so on—often rely on one or more of the three techniques.To get yourself started in a new direction, try the Three M’s:Modify your environmentPeople who have never tried this are astonished by the enormous effect it often has. I’ve known several people who have overe nail-biting simply by buying 50 nail files and distributing them everywhere: in their pockets, their desks and their bedrooms. With a nail file always within reach, they tended to groom rather than bite. To change yourself, change your world.Monitor your behaviorI’ve been reading researc h studies on self-monitoring for 20 years, and I’ve conducted some myself. The fact is, if youmonitor what you do, you’ll probably do better.A study by Canadian researchers showed that teenagers arrived more promptly at a swim practice when they were given an attendance sheet to record their arrival times. Sonya Carr and Rebecca Punzo reported that self-monitoring improves academic performance of emotionally disturbed children in reading, mathematics and spelling. Dozens of studies have similar results, all inspired by heightening our awareness of our behavior.Make mitmentsWhen you mit yourself to another person, you establish a possibility of reinforcement (后效强化)；you’ve automatically arranged for a reward if you stick to it and a punishment if you don’t. It puts some pressure on you, and that’s often just what you need.For instance, if you want to exercise more, arrange to do it with a friend. If you don’t show up, your friend will get angry, and that may be just the ticket to keeping you punctual(准时的). In 1994 Dana Putnam and other researchers showed that patients who made written mitments were far morelikely to take prescribed medicine than patients who hadn’t.There’s good news here for all of us. We can meet many of the demands and overe many of the challenges of life with simple skills that anyone can master an d that don’t require willpower---in other words, with skill, not will.Change your bad habits to goodParagraphoutlineSupporting detailsIntroduction[·Most of self-change techniques that have beensuggested before are ( 71 )________.·People who are ( 72 ) ________in making changes intheir lives often rely on one or more of the Three M’s.Modify your ( 73 ) ________·Those who have never tried this method can( 74 ) ________enormously from it.·Several people have overe nail-biting with a nail file always( 75 ) ________reach.(76)________your behavior ·If you monitor what you do, you are very( 77 )________to do better.·The more you bee( 78 ) ________of what you’re doing, the better you will perform.Make mitments·mitting yourself to someone else will pressure you tocarry it out, which helps reward yourself.·The patients who made written mitmentsprobably( 79 )________。
新概念英语第二册课后习题答案详解_and_单元测试答案(全)之欧阳治创编
新概念英语第二册课后习题答案详解Lesson 11. b选b最为正确。
因为a.d.都与课文内容不符合，也不合乎逻辑；c.的意思是“他们没有注意他”，而作者的意图并不是想让他们注意他，而是想让他们停止谈话。
所以选b. 最能表达作者当时心里的感受。
2．c其余3个答案都与原句意思不符合。
3．b因为a. to 不对，可以是He went to the theatre;c. into 也不对，可以是He went into the theatre;d. on更不符合语法，表示在某一个地方用介词in 或at, in 表示在大的空间，如国家，城市等，at 则表示在小的地点或空间，如atthe office, at the theatre 等, 所以选b.是正确的。
4．db. above(在……上方)；c. ahead of (在……的前面，在……之前)不和behind 对应，也不强调位置的前后顺序。
a. before 和 d. infront of 都是和behind对应的，都有“在……前面”的意思。
但in front of 更具体的强调位置，而before则包含更宽泛的意思，即时间上，空间，次序，登记，重要性方面的“在……前面”5．c因为用 a. Where, b. why, d. when 提问都不符合逻辑，都不是针对状态提问的，只有How提问，才能用Angry回答。
6．ab. they 只做主语； c. their只能做定语；d. us 虽然可以做宾语，但与前一句意思不符合。
7．da. none是代词，很少用在名词前面；b. any 只能用在否定句或疑问句中；c. not any 不符合语法，因为前面没有助动词did.8.ba. chair(椅子)， c. armchair(手扶椅) d. class(班级) 这3个选择都和seat的意思不符合。
Seat是”座位，座席” 的意思。
强调的是可供坐下的地方，不是具体的椅子。

高二英语作业2 答案解析
高二英语作业2I.阅读理解Reuel Tolkien (1892－1973), the British linguist, writer. He created a fantasy novel “The Lord of the Rings” the wellknown trilogy (三部曲)．Tolkien was born in Bloemfontein, South Africa. When he was 4 years old, his father died and his family moved back to England. Tolkien graduated from Oxford University when he was 23 years old, and participated in the First World War. During the war, Tolkien suffered from “trench fever” and stayed in the hospital until the end of World War Ⅰ. It was the days in the hospital that he began his writing career first.After the war, Tolkien became a linguist. He was an editor of the “New English Dictionary” of 1918－1920. However, he was more researching in to AngloSaxon language which makes his extensive contacts in Britain and the Nordic spread all over the folklore and mythology.In 1937, Tolkien completed his first work “The Hobbit”. Although this was a fairy tale, it was also suitable for adults to read. Because of good sales, the publisher Allen & Unwin convinced Tolkien to write its sequel. This encouraged Tolkien to complete his most famous works the epic (史诗) trilogy “The Lord of the Rings”. The works of writing went on for almost a year with the support from his good friend Lewis. At the beginning “The Lord of the Rings” was similar works for children, but after that writing style quickly became serious and dark. “The Lord of the Rings” was one of the most popular literary works in the 20th century in terms of sales and readers' evaluation. Tolkien's influence is important, for the success of “The Lord of the Rings” makes the fantasy novels of this literature genre (体裁) develop rapidly.【语篇解读】本文是一篇人物传记，介绍了《指环王》的作者瑞尔·托尔金的生平。

Indeed it is. Scientific studies have proven it. Music has so many good effects on our body, mind and mood that this world will certainly not be a good place without music. Then, is music good for children? Some parents think so and let their children learn or listen to music. But some parents don't know the importance of music to children. Here are some reasons why music is important to children.First, music is good for children's intelligence. Studies have proved that children who learn music are likely to have higher intelligence than those who have no interest in or dislike music. This is because the brain gets stimulated (刺激) by the rhythm and tone of music.Music also has soothing (抚慰的) effect on children and helps remove their stress. Today's children are under a lot of stress from schoolwork. Being under too much stress impairs children's health. Luckily, listening to music can help them feel better.Music can improve children's moods. Some children are sad by nature. They seem to be lost in their own thoughts and don't take interest in their surroundings. In such cases, a method known as “music therapy” comes to thei r rescue. It changes their moods and places a new kind of spirit in them.Music is also a universal language that children ought to learn. Our world has become a global village. People are getting more and more interested in other cultures and countries. Music can help them in understanding foreign cultures.Now we can say that music is very important not only to adults but also to children. So children should be encouraged to learn music or listen to music.【解题导语】小孩接触音乐对他们很有好处，父母应该多让小孩接触音乐。

Is life easier when people don't need to carry any coins for (#currency#) at all? Is money heavy to carry? Is it safe to carry money? Maybe in the future each of us will have only one small plastic credit card. We will use it to buy all the things we now buy with money. We will not need money to pay for things. Of course we may still have some of the same problems with cards that we now have with money. Sometimes we lose money. Maybe we will lose the cards. People steal money. Maybe someone will take the card. Someone may even make a card that looks like our card. Since we can't buy anything without our cards, the credit card may be no better than currency. Is there something even easier to use than credit cards? All of us have a thumbprint. No two thumbprints are the same. Maybe someday the government will keep people's thumbprints with a number. No person will have the same thumbprint or number. When you want to buy something you will put your thumb on a machine or a computer. Each store or business will have one. Everyone's thumbprint will be in the computers. It will be very difficult to lose our thumbprints. It will be difficult for someone to steal it or make one like it.1)． According to the passage, we all need _____B___.A． coins B． some kind of money C． currency D． credit cards2)． Which one of the following gives the main idea of Para. 2? CA． Credit cards are worse than currency.B． We use credit cards because people steal money.C． We have many problems with money.D． Currency may not be more of a problem than credit cards.3)． Our thumbprints may be used in the future because ____D____.A． each store will have a computer B． computers need themC． they will help each store D． every thumbprint is different4)． Which of the following statements is NOT true? CA． Every person will have a different thumbprint number.B． There are some problems with the use of credit cards.C． There are no problems with currency.D． There is something easier to use than credit cards.5)． The word "currency" most probably means "____D____".A． plastic cards B． metal money C． paper money D． coins2． Despite laws designed to keep cigarettes away from kids, 34 percent of U.S. high school studentsand 15 percent of middle school students use tobacco products, government health officials say. Those figures mean more than three million kids between the ages of 12 and 17 are (*lighting up*), accordingto the national survey by the Centers for Disease Control's Office of Smoking and Health. The survey,which included students from 29 states, posed a number of questions to teenagers about tobacco marketing, second-hand smoke and underage purchasing, as well as general use of all types of tobacco products.Although the statistics show the number of teens using tobacco has started to decline from recordhighs in 1997, experts say the numbers are still disturbing given that nearly 90 percent of adult smokersbegan using tobacco at or before the age of 18. "We want to emphasize, while cigarettes are the mostlethal (致命的) form of tobacco, adolescents are using many forms of tobacco, and potentially becoming addicted to nicotine from many sources, and will transit into cigarettes," said Terry Pechacek, headof the survey team and associate director for science with the CDC Office on Smoking and Health. Accordingto the survey, most middle and high school smokers get their tobacco at gas stations and convenience stores. While the legal age to buy tobacco is 18 throughout most of the United States, the survey shows current laws to be ineffective. Approximately 69 percent of middle school students and 58 percent ofhigh school students reported they were not asked for proof of age when purchasing cigarettes. Althoughthe tobacco industry has altered its advertising, ads still lure (引诱) teens into buying tobacco products, Pechacek said. "Tobacco companies voluntarily stopped outdoor billboards, but have taken these advertising dollars and put them into local convenience stores," he said. The study also found one ofthe "major predictors" of tobacco use to be whether teens spend time with other people who smoke. Inthe week before the survey, half of the nonsmokers were in a room with someone smoking, and approximately70 percent of middle school students and 57 percent of high school students who smoke live in a homewith a smoker. Experts believe that more education about tobacco in schools could counteract the bad influences these students face at home. "Overall, we're finding that many students are receiving some information, but the rate is far below what is recommended," said Pechacek.1)． What does the passage mainly discuss? DA． Smoking and health. B． Harm of teenage smoking.C． Cigarettes in convenience stores. D． Problems of teenage smoking in the U.S.2)． Which of the following is NOT a cause for the teenage smoking problems B in the U.S. according to the passage?A． Ineffective current laws about the legal age of using tobacco.B． Lack of supervision in school and at home.C． Bad influences from smokers.D． Tobacco advertisement.3)． Which is true according to the passage? BA． No laws in the U.S. have been designed to keep cigarettes away from kids.B． There are more smokers in U.S. high schools than middle schools.C． Since 1997, the number of teenagers using tobacco has been on the rise.D． More than four million young people between the age of 12 and 17 smoke.4)． "Lighting up" in Para. 1 probably means ______B____.A． brightening up B． smoking C． giving light to D． becoming suddenly happy5)． What can we learn about smoking in the U.S.? DA． Most adult smokers began using tobacco at or before the age of 18.B． In most of the U.S., the legal age to buy tobacco is 16.C． Young smokers can't buy cigarettes in gas stations or conveniencestores.D． The most common form of tobacco adolescents use is cigarette.3． Passage 2On May 12, 1946, Louis Alexander Slotin was on an experiment in the laboratories at Los Alamos with seven other men. Slotin, then aged thirty-five, was concerned with the assembly of pieces of plutonium (钚),each of which alone is too small to be dangerous, and which will only generate (产生) a chain reaction when they are put together. Slotin himself had tested the assembly of the first experimental bomb which had been exploded in New Mexico in July, 1945. Now, nearly a year later, Slotin was again doing an experiment of this kind. He was pushing toward one another, by tiny movements, several pieces of plutonium, in order to ensure that their total mass (质量) would be large enough to make a chain reaction. Suddenly, the screwdriver (螺丝起子) slipped, the pieces of plutonium came too close together and a chain reaction began. This was filling the room with radioactivity. Slotin moved at once: he pulled the pieces of plutonium apart with his bare hands (赤手). This was a real act of suicide, for it exposed him to the largest amount of radioactivity (放射能). Then he calmly asked his seven co-workers to mark their precise positions at the time of the accident, in order that the degree of exposure of each one to the radioactivity could be fixed. Having done this and called the medical service, Slotin apologized to the others, and said what turned out to be exactly true: that he thought that he would die and that they would recover. Slotin had saved the lives of the seven men working with him by cutting to a minimum the time during which the assembly of plutonium was giving out radioactive rays. He himself died of radiation sickness nine days later.1)． Which of the following statements is TRUE?（D ）A． Slotin was a careless person.B． Slotin's co-workers rushed to help him.C． Slotin's co-workers were not harmed.D． Before Slotin pulled the pieces of plutonium apart, the room had been filled with radioactivity.2)． Why did Slotin pulled with his bare hands?（ A）A． Because there was no time to put on gloves.B． Because he forgot to wear any gloves.C． Because he didn't like to wear gloves.D． Because there was no gloves in the lab.3)． Slotin was a scientist in the field of （ B）.A． mathematics B． physics C． biology D． psychology4)． Slotin's response to the emergency could be best described as（A ）.A． brave and quick B． nervous and slow C． stupid and suicidal D． hasty and incorrect5)． Slotin set a good sample in（ D）.A． morality B． wisdom C． modesty D． devotion to science4． A mouse engineered at Harvard Medical School has become the first patented(申请了专利的) animal.Born with cancer-promoting genes, the new breed may be invaluable in the study of cancer. But the patenthas aroused debate over whether humans have the right to create and own novel life forms.To create the mice, Philip Leder's genetics (遗传学) team injected fertilized mouse eggs with hundreds of copies ofa cancer gene. Mice that developed from the eggs carried the "oncogene" and passed it to (#offspring#).Thus arouse a breed that is born with breast cancer.The patent, which covers the creation of any oncogene-carrying mammals(哺乳动物) except humans, has opponents. Ever since 1980 when the Supreme Courtruled that bacteria could be patented, critics have attacked the idea that one species can own another.And because a patent guarantees a monopoly (垄断), critics fear that patenting a laboratory animal may increase costs of research and, finally, new drugs.Congressional committees are studying the implications,and legislation (立法) is being considered to either prohibit animal patents or impose a two-year termon them. The U. S. Patent and Trademark Office is busy studying too: 21 applications for new animalsare coming.1)． "Offspring" in Para. 2 means（ D）。

t t αα-+=
air t －由气象参数决定
但围护结构外表面的对流换热系数out α，围护结构外表面对太阳辐射的吸收率a ，围护结构外表面与环境的长波辐射换热量L Q 与围护结构外表面的性质（材料、粗糙度、形状等）有关。
所以室外空气综合温度应该是气象参数与围护结构表面特性共同作用的结果。
2． 什么情况下建筑物与环境之间的长波辐射可以忽略？
答：计算晴天白天太阳直射下的辐射换热时，由于太阳辐射远远大于长波辐射，可以忽略长波辐射。
3． 透过玻璃窗的太阳辐射中是否只有可见光，没有红外线和紫外线？
答：否。
由普通玻璃的光谱透过率（书中图3－3）图中可知，可见光和短波红外线的通过率比较高，而长波红外线和紫外线的透过率很低，因此透过玻璃窗的太阳辐射主要为可见光和短波红外线，但也包含少量的长波红外线和紫外线。
4． 透过玻璃窗的太阳辐射是否等于建筑物的瞬时冷负荷？
答：不是。
太阳辐射进入室内后，首先被室内各种表面吸收和贮存，提高这些表面的温度，然后通过对流换热方式逐步释放到空气中，形成瞬时冷负荷，在时间上有所延迟，并不等于该时刻的瞬时冷负荷。
同时，计算建筑物的瞬时冷负荷还应考虑围护结构导热、室内热源散热等因素。
5． 室内照明和设备散热是否直接转变为瞬时冷负荷？
答：不是。
室内照明和设备散热一般包括对流换热和辐射换热两种形式。
其中，对流换热部分立刻就进入到室内空气中成为瞬时冷负荷，而辐射得热部分首先会传递到室内各表面，提高这些表面的温度。
当这些表面的空气温度高于室内空气温度时，就会有热量以对流换热的形式进入到空气中，成为瞬时冷负荷。
所以室内照明和设备散热只有部分直接转变为瞬时冷负荷。
6． 为什么冬季往往可以采用稳态算法计算采暖负荷而夏天却一定要采用动态算法计算空调负荷？
答：稳态计算法即不考虑建筑物以前时刻传热过程的影响，只采用室内外瞬时或平均温差与围护结构的传热系数、传热面积的积来求取负荷值，即Q = KF ∆T 。
如果室内外温差的平均值远远大于室内外温差的波动值时，采用平均温差的稳态计算带来的误差也比较小，在工程设计中是可以接受的。
例如在我国北方的冬季，室外温度的波动幅度远小于室内外的温差（见图），因此目前在做采暖负荷计算时，采用的是日平均温差的
稳态计算法，即：Q hl = K w F w (t o - t in )
其中t o 采用是冬季室外设计温度，对于空调系统为每年不保证1天、对于采暖系统为每年不保证5天的最低日平均温度；t in 是冬季室内设计温度。
图 冬夏室内外温差比较举例 但计算夏季冷负荷是不能采用日平均温差的稳态算法的，否则可能导致完全错误的结果。
因为尽管夏季日间瞬时室外温度可能要比室内温度高很多，但夜间却有可能低于室内温度，因此与冬季相比，室内外平均温差并不大，但波动的幅度却相对比较大，见图。
如果采用日平均温差的稳态算法，则导致冷负荷计算结果偏小。
另一方面，如果采用逐时室内外温差，忽略围护结构的衰减延迟作用，则会导致冷负荷计算结果偏大。
7． 围护结构的内表面上的长波辐射对负荷有何影响？
答：长波辐射将转化为负荷，但存在着延迟和衰减。
以夏季围护结构表面的长波辐射为例，此时围护结构内表面温度高于其他表面，热量会以长波辐射的形式传给室内其他表面，提高其他表面的温度。
当这些表面的空气温度高于室内空气温度时，就会有热量以对流换热的形式进入到空气中，成为瞬时冷负荷。
冷负荷空气其他表面高温表面成为瞬时负荷对流换热长波辐射−−−−→−−−−→−−−−→−
因此，对于建筑物冷负荷而言，长波辐射所传递的热量将转化为建筑物负荷，但长波辐射不是马上转化为建筑物的瞬时负荷，两者之间存在着相位差和幅度差，冷负荷对得热的响应一般都有延迟，幅度也有所衰减。
同理可分析围护结构内表面温度低于其他表面时的情况。
8． 夜间建筑物可通过玻璃窗长波辐射把热量散出去吗？
答：可以
室内空气和表面可以通过对流换热和长波辐射加热玻璃窗的内表面，而玻璃窗被加热后则会以长波辐射的方式把热量散发出去。
外界环境玻璃窗内表面被加热室内空气、表面长波辐射对流换热、长波辐射−−−→−−−−−−−→− 冬季夜间通过玻璃窗表面的长波散热很厉害，这就是为什么可关闭的外遮阳在冬季夜间保温效果很明显的原因。
9．如果一个由6面实体墙（包括楼板）围合的房间室内温度恒定，把几面实体墙的得热叠加，再加上室内热源得热与渗透风得热，就等于房间的冷负荷？
1.几面实体墙的得热量HG wall是在假定“除所考察的围护结构内表面外，其他各室内表面的温度均与室内空气温度一致，室内没有其他短波辐射热量落在所考察围护结构内表面上”时，计算得到的。
实际上，室内其他表面的温度常常与室内空气温度不一致，室内也存在着辐射源，它们之间的辐射换热会影响所考察的围护结构向室内的传热量。
举例来说，如果室内辐射热源正好全打在外墙内表面上，此时向室内传的热量会被顶出去一部分，得热跟实际传到室内空气的热量差得就更大了。
2.室内热源得热量可以分成对流散热部分和辐射散热部分，其中对流散热部分可以直接转化为瞬时冷负荷，但是辐射散热部分会通过长波辐射方式传递到室内围护结构和家具各表面，再通过对流方式逐步进入到室内空气中，形成冷负荷。
因此也不能直接将室内热源得热简单的叠加到冷负荷中。
3.当然，如果室内各内表面温度都跟空气温度一样，室内热源基本上只有对流散热，题中的得热之和基本就等于冷负荷。
10．如果有两套户型设计一模一样的公寓，但一个主要窗户朝东，另一个朝西。
两套公寓夏季的热环境条件有何区别？
朝西的公寓热环境较差。
上午时候室外温度较低，下午时候室外温度较高；在上午时进入朝东公寓的太阳辐射得热量较多，在下午时进入朝西公寓的太阳辐射量较多。
对于朝东公寓，传热的峰值在下午，太阳辐射得热的峰值在上午，峰值错开使得负荷峰值较小，对于不空调的房间一天中的室内温度有可能都不超出人体的舒适区；对于朝西公寓，传热和太阳辐射的峰值均在下午，峰值叠加后使得总负荷偏大，对于不空调的房间下午的温度会特别高造成人体的不适。
