The worker who gets a promotion the students whose grades improve , the foreigner who learns a new language ---all these are examples of people who have measurable results to show for their efforts.By ________-the process of personal growth is much more difficult to determine , since by definition it is a journey and not the specific signposts or landmarks along the way . The process is not the road itself , but rather the attitude and feelings people have , their caution or courage , as we _______new experiences and unexpected obstacles. In this process , the journey never really ends.

Reading ComprehensionSection ADirections: For each blank in the following passage there are four words or phrases marked A, B, C and D. Fill in each blank with the word or phrase that best fits the context.To Apologize or Not to ApologizeWhy difficult ?When we do wrong to someone we know, even not _________, we are generally expected to apologize so as to improve the situation .

It is a performance in which every word or expression _________, as they become part of the public record . Refusing to apologize can be smart , or it can be stupid . So , readiness to apologize can be seen as a sign of strong character or as a sign of weakness .Why now ?The question of whether leaders should apologize publicly has never been more _______. During the last decade or so , the United States in particular has developed an apology culture ------apologies of all kinds and for all sorts of wrongdoings are made far more ________than before. More newspaper writers have written about the growing importance of ________-apologies . Meanwhile , more and more articles , advice colums , and radio and television programs have similarly dealt with the subject of _______apologies . Although they are not carried out in the public places , we can’t neglect the importance of this performance.Why ________?Why do we apologize?

A. politically B. professionally C. academically D. physically54. A. avoidance B. admission C. involvement D. elimination55. A. fulfillment B. statement C. occupation D. strategySection BDirections:Read the following three passages. Each passage is followed by several questions or unfinished statements. For each of them there are four choices marked A. B, C and D. Choose the one that fits best according to the information given in the passage you have just read.(A)If your in-box is currently reporting unread messages in the hundreds or thousands, you might have a hard time believing the news: e-mail is on the decline.At first blush, that might seem to be the case. The incoming generation, after all, doesn't do e-mail. Oh, they might have an account. They use it only as we would a fax machine: as a means to communicate with old-school folks like their parents or to fulfill the sign-up requirements of Web sites. They rarely check it, though.Today's instant electronic memos—such as texting and Facebook and Twitter messages—are more direct, more concentrated, more efficient. They go without the salutation(称呼语) and the signoff; we already know the “to” and “from.” Many corporations are moving to messaging networks for exactly that reason: more signal, less noise and less time. This trend is further evidence that store-and-forward systems such as e-mail and voicemail are outdated. Instead of my leaving you a lengthy message that you pick up later, I can now send you an unobtrusive, easily -consumed message that you can read—and respond to—on the go.The decline of e-mail corresponds neatly to the dawn of the mobile era. Instantaneous(及时) written messages are different. These are neatly tailored to fit in just about any time: before a movie, in a taxi, waiting for lunch. And because these notes are invariably brief, they're a natural for smartphone typing. With these formats, you also have control over who can correspond with you, which you usually don't in e-mail. And especially on Facebook, instant messaging can take on the character of a chat room, where several people can talk at once.Does this mean e-mail is on its way to the dustbin of digital history? Not necessarily. E-mailstill has certain advantages. On the other hand , tweets and texts feel ephemeral—you read them, then they're gone, into an endless string, e-mail still feels like something you have and that you can file, search and return to later. It's easy to imagine that it will continue to feel more appropriate for formal communications: agreements, important news, longer explanations.So, e-mail won't go away completely. Remember, we've been through a transition like this not so long ago: when e-mail was on the rise, people said that postal mail was dead. That's not how it works. Postal mail found its smaller niche, and so will e-mail. Technology rarely replaces an institution completely; it just adds new avenues.56. What would the incoming generation like to do with their e-mail accounts?A. Contact close friendsB. Send long messagesC. Fill in some formsD. Communicate with their colleagues57. Which of the following is mainly discussed in the paragraph 3 and 4?A. The possible reasons behind the decline of e-mailB. The likes and dislikes of the young generationC. The rapid development of e-communication channelsD. Evidence about the uncertain future of easily –consumed messages58. What does the underlined word “ephemeral” in paragraph 5 mean ?A. Automatically –sendingB. Randomly –writtenC. Hardly –recognizedD. Shortly –appearing59. According to the passage , which of the following statements is true ?A. It’s too early to determine the decline of e-mailB. E-mail has reasons to exist on its own advantageC. E-mail , just like postal mail has come to its endD. We should feel sorry for the decline of e-mail(B)A. reveal the fact that Nick wants to know more about Gatsby.B. show the version of Rhapsody in Blue matches the film well.C. prove that the director is good at combining visual and music.D. convince us that the first scene is perfectly filmed by the director.61. According to Time Magazine, what did Baz Luhrmann do to make the film a success?A. He adapted the story in the novel as he wished.B. He made the film more powerful than the book.C. He mixed his style with the elegance of the book.D. He changed the story to meet his own style.62. Which of the following can be used to describe Gatsby?A. Faithful and warm-hearted.B. Charming and professional.C. Selfish and timid.D. Mysterious and devoted.(C)The British Medical Journal recently featured a strong response to what was judged an inappropriately merciful reaction by a medical school to a student cheating in an examination. Although we have insufficient reliable data about the extent of this phenomenon, its prevention, or its effective management, much can be concluded and acted upon on the basis of common sense. There is general agreement that there should be zero tolerance of cheating in a profession based on trust and one on which human lives depend. It is reasonable to assume that cheaters in medical school will be more likely than others to continue to act dishonestly with patients, colleagues, and government.The behaviors under question are multifactorial in origin. There are familial(家庭的), religious, and cultural values that are acquired long before medical school. For example, countries, cultures, and subcultures exist where bribes and dishonest behaviour are very normal. There are secondary schools in which neither staff nor students tolerate cheating and others where cheating is common; there are homes which cultivate young people with high standards of moral behaviour and others which leave moral training to the harmful influence of television and the market place.Medical schools reflect society and cannot be expected to remedy all the ills of a society. The selection process of medical students might be expected to favour applicants with positive moral behaviour. Medical schools should be the major focus of attention for cultivating future doctors with moral sensitivity. Unfortunately there are troubling data that suggest that during medical school the moral behaviour of medical students does not necessarily improve; indeed, moral development may actually stop or even regress(倒退).It is critical that the academic and clinical leaders of the institution set a personal example on moral behaviour. Medical schools must do something to make sure that their students are expected to be clear from day one. The development of a school's culture of moral behaviour requires cooperation with the students in which they play an active role in its creation and developing. Moreover, the school's examination system and general treatment of students must be fair. Finally, the treatment of infractions must be firm, fair, transparent(透明的)63.

Summary WritingDirections: Read the following passage. Summarize the main idea and the main points of the passage in no more than 60 \words. Use your own words as far as possible.There are various means consumers can do if they find that an item they bought is faulty or in some other way does not live up to the manufacturer’s claims. A simple and common method used by many consumer is to complain directly to the store manager. In general, the "higher up" his or her complaint, the faster he or she can expect it to be settled. In such a case, it is usually settled in the consumer's favor, assuming he or she has a just claim.Consumers should complain in person whenever possible, but if they cannot get to the place of purchase, it is acceptable to phone or write the complaint in a letter.Complaining is usually most effective when it is done politely but firmly, and especially when the consumer can demonstrate what is wrong with the item in question. If this cannot be done, the consumer will succeed best by presenting specific information as to what is wrong, rather than by making general statements. For example, “The left speaker does not work at all and the sound coming out of the right one is unclear” is better than “This stereo does not work”. The store manager may advise the consumer to write to the manufacturer. If so, the consumer should do this, stating the complaint as politely and firmly as possible. If a polite complaint does not achieve the desired result, the consumer can go to a step further. She or he can threaten to take the seller to court or report the seller to a private or public organization responsible for protecting consumer’s rights.V.
