参考解析
解析：本篇文章主要介绍了两种光盘储存文件和读取文件的方式。
根据第一段第二句可知，声音是以特殊数字——数码的形式存储在光盘上的。
根据第三段第一句“Digital codes are used with many technologies.”可知，第三段主要讲的是数字代码的用处，紧接着又举电子邮件的例子来对数字代码的用处进行说明。
根据第四段第三句可知，CD-RWs可以被重写。第四段第八句中的“CD-ROM stands for Compact Disk-Read Only Memory”则表明，CD-ROMs指的是“只读存储光盘”，即只能读取而不能重写的光盘。由此可知，两者的区别在于能否被重写。
根据第五段最后一句可知，如果得到很好的照顾，光盘可以使用很长时间。
根据第六段第二句可知，全新的音乐存储技术在不远的将来有可能实现，可见存储音乐的新技术正在被研发。

Maybe it is true that we don't know what we have got until we lose it, but it is also true that we don' t know what we have been missing until it arrives. Giving someone all your love is never an assurance that they will love you back. Don’t expect love in return; but be content that love has grown in your own heart.It takes an hour to like someone, a day to love someone, but it takes a lifetime to forget someone. Don’t rely on one's appearance; it can deceive. Don’t rely on wealth; even that fades away. Rely on someone who makes you smile, because it takes only a smile to make a dark day seem bright. There are moments in life when you miss someone so much that you just want to pick them from your dreams and hug them. Dream what you want to dream; go where you want to go; be what you want to be, because you have only one life and one chance to do all the things you want to do. May you have enough happiness to make you sweet, enough trials to make you strong, enough sorrow to keep you human, enough hope to make you happy.Always put yourself in others' shoes. If you feel that it hurts you, it probably hurts others, too. The happiest of people don't necessarily have the best of everything; they just make the most of everything that comes along their way. Happiness waits for those who cry, those who have been hurt, those who have searched, and those who have tried, for only they can appreciate the importance of people who have touched their lives.The brightest future will always be based on a forgotten past. You can't go on well in life until you let your past failures and heartaches go off. When you were born, you were crying and everyone around you was smiling. Live your life so that when you die, you are the one who is smiling and everyone around you is crying.(1)You should rely on someone who makes you smile_______________.A、because a smile can make your dark time easier.B、because a smile is bright.C、because you have nothing.D、because you can believe someone(2)What does the word “assurance” mean in the first paragraph?A、returnB、promiseC、maintainD、storage(3)In the third paragraph, “Always put yourself in other's shoes” means_______________.A、you should try other's shoes before you buy it.B、you should make yourself small enough.C、you should consider from another person's aspect.D、None of the above.(4) If you are the one who is smiling and everyone around you is crying when you die, you areA、SatisfiedB、UpsetC、SadD、Indifferent(冷漠的)(5)What has been mentioned in the passage?A、to tell us not to demand too muchB、to warn us not to believe in appearanceC、to consider other people and learn to forgiveD、all of the above
CIs there someone you hate? Well, maybe you don’t really hate them. But you get really angry every time you think of them. If you don’t let this anger go, it can turn into bitterness (痛苦).Bitterness appears when we can’t forgive (原谅) someone who has hurt us or made us angry. Someone might say or do something that hurts us. But instead of controlling the anger, we keep it deep inside. Before long, a bitter feeling begins to grow. We may think we’re hurting that person by criticizing (指责) him or her often, but we’re really only hurting ourselves.Bitterness can not only lead to serious health problems such as heart disease, but also hurt our relationships with friends and family members. No one enjoys being around an angry person for very long.If you see bitterness in your life, here are some ways to deal with it.l Accept itInstead of trying to deny your anger, make it clear to yourself and accept it. See your anger for what it is and quickly deal with it.l Stop making excuses for itYou may feel you have a right to be angry. You may think you’re right and the other person is wrong. You may even secretly enjoy making the other person look bad. But in the end, bitterness hurts you much more than the other person. The bitterness will hold you back, and the other person will go on with his or her life.l Forgive and forget itYou probably can’t completely put the anger out of your mind. But you can decide to forgive the other person. Forget it and move on. You’ll enjoy better health and peace of mind.66. According to the passage, we might get angry when someone __________.A. holds us back B. forgets us C. doesn’t like us D. does hurt us
DMy father was 44 and knew he wasn’t going to male it to 45. He wrote me a letter and hoped that something in it would help me for the rest of my life.Since the day 1 was 12 and first read his letter, some of his words have lived in mybeart. One it aways times out. “Right now, you are pretending to be a time-killer. But I know that one hay, you will do something great that will set you among the very best.” Knowing that my dad believed in me gave me permission to believe in myself. “You will do something great.” He didn’t know what that would be, and neither did I, but at times in my life when I’ve felt proud of myself, I remember his words and wish he were here so I could ask. “Is this what you were talking about, Dad? Should I keep going?”A long way frim 12 now, I realize hew would have been proud when I made any progress. Lately, thongn. I’ve come to believe he’d want me to move on to winat com next: to be nrood of and believe in, somebody else. It’s time to start writing my own letters to my children. Our children look to us with the same unanswered question we had. Our kids don’t hold back because they’re afraid to fail. They’re only afraid of failing us. They don’t worry about being disappointed. Their fear－as mine was until my father’s letter－is of being a disappointment.Give your chikdren permission to succeed. They’re witing for you to believe in them. I always knew way parents loved me. But trust my That elic will be more comlece, that love will be more real, and their belief in the nelces whi be greater if you write the words on their hearts; “Don’t worry; you’ll do something great.” Not having that blessing from their parents may be the only thing holding them back.68.We learn from the text that the author .A.lost his father when he was youngB.worked hard before he read his father’s letterC.asked his father permission to believe in himselfD.knew execty at thing his father wanted him to do

But, in fact, the members of all the groups to which you belong also depend on you to give that feeling to them.A person who shows that he wants everything for himself is bound（一定的）to be a lonely wolf.2 The need for companionship is closely related to the need for a sense of belongingness. How sad and lonely your life would be if you had no one to share your feelings and experiences.You may take it for granted that there will always be people around to talk to and to do things with you and for you.The important point,however,is that keeping emotionally healthy does not depend so much upon having people around you as upon your ability to establish relationships that are satisfying both to you and to them.3 Suppose you are in a crowd watching a football game.You don't know them.When the game is over,you will all go your separate ways.But just for a while you had a feeling of companionship,of sharing the feelings of others who were cheering for the team you wanted to win.4 An experience of this kind gives the clue（线索）to what companionship really is. It depends upon emotional ties of sympathy,understanding,trust,and affection.Companions become friends when these ties are formed.5 When you are thrown in a new circle of acquaintances（熟人）,you may not know with whom you will make friends,but you can be sure that you will be able to establish friendships if you show that you really like people. If you had no one to share your feelings,your life would be_______.A:without pityB:sad and lonelyC:emotionally healthyD:without real love for themE:a sense of securityF:a lonely wolf
共用题干第三篇It is natural for young people to be critical of their parents at times and to blame them for most of the misunderstandings between them.They have always complained,more or less justly,that their parents are out of touch with modern ways;that they are possessive and dominant;that they do not trust their children to deal with crisis;that they talk too much about certain problems;and that they have no sense of humor,at least in parent-hild relationships.I think it is true that parents often underestimate their teenage children and also forget how they themselves felt when young.Young people often irritate their parents with their choices in clothes and hairstyles,in entertainments and music.This is not their motive.They feel cut off from the adult world into which they have not yet been accepted.So they create a culture and society of their own.Then,if it turns out that their music or entertainments or vocabulary or clothes or hairstyles irritate their parents,this gives them additional enjoyment. They feel they are superior,at least in a small way,and that they are leaders in style and taste.Sometimes you are resistant and proud because you do not want your parents to approve of what you do.If they did approve,it looks as if you are betraying your own age group.But in that case, you are assuming that you are the underdog:you can't win but at least you can keep your honor. This is a passive way of looking at things.It is natural enough after long years of childhood,when you were completely under your parents' control. But it ig而res the fact that you are now beginning to be responsible for yourself.If you plan to control your life,cooperation can be part of that plan.You can charm others,especially your parents,into doing things the way you want.You can impress others with your sense of responsibility and initiative,so that they will give you the authority to do what you want to do.Teenagers do not want their parents to approve of whatever they do because they_________.A:have been accepted into the adult worldB:feel that they are superior in a small way to the adultsC:are not likely to win over the adultsD:have a strong desire to be of independence

共用题干第三篇Compact DisksIf someone says to you your music CDs don't really hold any music on them,and they only have numbers recorded on them,you may not believe it.In fact,he is right in that sound is actually recorded onto the CDs as special numbers-a digital code.The code is pressed onto the CD as bumps（隆起）on a long spiral track almost five kilometers long.These bumps are an average of 0.5 microns（微米）wide.A small laser beam shines onto the bumps as the CD turns.The light is reflected back to a receiver that records how the laser light bounces back.This lets the CD player turn the reflected light back into the original code.This means you can hear the original code as music.Digital codes are used with many technologies.E-mail needs these kinds of code numbers.Space probes （探测仪）communicate with their ground station on earth using digital codes.Bar codes are read as digital codes in computer systems.Digital communications with cell phones need digital codes.Weather radios also tune in to specific signals using these codes.There are many types of compact disks.One format is called CD-RWs.They can be recorded on and re-recorded on(rewritten on)as you would do with a floppy disk（软盘）.Another format is the CD-ROM.The technology for recording on these disks is different from other CDs.These CDs have a dye layer that the CD writer can darken or leave clear.The clear and dark spots are the digital code.CD-ROM stands for Compact Disc-Read Only Memory.This disk is like a"super" floppy disk that can hold lots of information.One CD-ROM can hold the same amount of data as 500 floppy disks.Information is permanently recorded onto it.Computer games and other programs are considered to be CD-ROMs.CDs were first sold to the public in 1982.These CDs still play well and sound fine.Current CDs are expected to last between 70 to 200 years.Of course,you can make sure your CDs last a long time by taking care of them.Science keeps on developing.It may not be many more years before a completely new technology is invented and introduced to the public for music recording.In the meantime,there is no doubt you will continue to enjoy listening to your favorite music on CDs and play your favorite computer games on CD-ROMs.It can be inferred from the passage that______.A:CD-ROMs are more expensive than other CDsB:new technology for music recording is being developedC:the author likes listening to musicD:floppy disks are no longer in use
