Task 1

Directions: After reading the following passage, you will find 5 questions or unfinished statements, numbered 36 through 40. For each question or statement there are 4 choices marked A, B, C, and D. You should make the correct choice.

The purpose of any selection interview is to choose the right person for the job in question or to select someone who shows potential for more senior posts. Interviews may not be the ideal method of selecting staff. For one thing, you will not know whether you have selected wisely until long after the interview. The period you have to wait will depend on the job in question. The lower the level of the job is, the quicker you will discover how good you were with your selection. Be clear what you are trying to achieve by the interview and how you intend to do it.

Interviewing requires many skills which typically only develop with practice. Be careful that you are not being subjective in your judgments(判断); try to be objective wherever possible. An example may illustrate the point. If you interview a long-haired male applicant, you may be put off by the length of his hair; you may associate the long hair with untidiness, dirt or laziness.

This is a subjective judgment—another interviewer may not be affected by hair length in the same way.

Subjective misjudgment is sometimes called the "halo and horn" effect. We meet someone neatly dressed and well-spoken, and from this we assume that they are all things good; that they will be reliable, honest, hard working, etc. We are blinded by their halo. Conversely, on meeting a roughly-spoken, scruffy(褴褛的)individual we decide they will be unreliable, careless and lazy. We only see their horns. This problem needs to be overcome, since we could so easily overlook first-class candidates(候选人)for vital posts because we have not been objective.

Which of the following best summarizes the main idea of the essay？

A．Things to pay attention to when interviewing job applicants.

B．Things to pay attention to when applying for a job.

C．Advice to how to be subjective.

D．The importance of a selection interview.

ThePerfect Essay

A) Looking back on too many yearsof education, I can identify one truly impossible teacher. She cared about me,and my intellectual life, even when I didn’t. Her expectations were highimpossibly so. She was an English teacher. She was also my mother.

B) When good students turn in anessay, they dream of their instructor returning it to them in exactly the samecondition, save for a single word added in the margin of the final page:”Flawless.” This dream came true for me one afternoon in the ninth grade. Ofcourse, I had heard that genius could show itself at an early age, so I wasonly slightly taken aback that I had achieved perfection at the tender age of14. Obviously, I did what any professional writer would do; I hurried off tospread the good news. I didn’t get very far. The first person I told was mymother.

C) My mother, who is just shy offive feet tall, is normally incredibly soft-spoken, but on the rare occasionwhen she got angry, she was terrifying. I am not sure if she was more upset bymy hubris(得意忘形) or by the fact that my Englishteacher had let my ego get so out of hand. In any event, my mother and her redpen showed me how deeply flawed a flawless essay could be. At the time, I amsure she thought she was teaching me about mechanics, transitions(过渡), structure, style. and voice. But what I learned, and what stuckwith me through my time teaching writing at Harvard, was a deeper lesson aboutthe nature of creative criticism.

D) Fist off, it hurts. Genuinecriticism, the type that leaves a lasting mark on you as a writer, also leavesan existential imprint(印记) on you asa person. I have heard people say that a writer should never take criticismpersonally. I say that we should never listen to these people.

E) Criticism, at its best, isdeeply personal, and gets to the heart of why we write the way we do. Theintimate nature of genuine criticism implies something about who is able togive it, namely, someone who knows you well enough to show you how your mentallife is getting in the way of good writing. Conveniently, they are also thepeople who care enough to see you through this painful realization. For me ittook the form. of my first, and I hope only, encounter with writer’s block—I wasnot able to produce anything for three years.

F) Franz Kafka once said:” Writingis utter solitude(独处), the descentinto the cold abyss(深渊) ofoneself. “My mother’s criticism had shown me that Kafka is right about the coldabyss, and when you make the introspective (内省的) decent that writing requires you are out always pleased by whatyou find.” But, in the years that followed, her sustained tutoring suggestedthat Kafka might be wrong about the solitude. I was lucky enough to find acritic and teacher who was willing to make the journey of writing with me. “Itis a thing of no great difficulty,” according to Plutarch, “to raise objectionsagainst another man’s speech, it is a very easy matter; but to produce a betterin its place is a work extremely troublesome.” I am sure I wrote essays in thelater years of high school without my mother’s guidance, but I can’t recallthem. What I remember, however, is how we took up the “extremely troublesome”work of ongoing criticism.

G) There are two ways to interpretPlutarch when he suggests that a critic should be able to produce “a better inits place.” In a straightforward sense, he could mean that a critic must bemore talented than the artist she critiques(评论). My mother was well covered on this count. But perhaps Plutarch issuggesting something slightly different, something a bit closer to MarcusCicero’s claim that one should “criticize by creation, not by finding fault.”Genuine criticism creates a precious opening for an author to become better onthis own terms—a process that is often extremely painful, but also almostalways meaningful.

H) My mother said she would helpme with my writing, but fist I had myself. For each assignment, I was write thebest essay I could. Real criticism is not meant to find obvious mistakes, so ifshe found any—the type I could have found on my own—I had to start fromscratch. From scratch. Once the essay was “flawless,” she would take an eveningto walk me through my errors. That was when true criticism, the type thatchanged me as a person, began.

I) She criticized me when Iincluded little-known references and professional jargon(行话). She had no patience for brilliant but irrelevant figures ofspeech. “Writers can’t bluff(虚张声势) theirway through ignorance.” That was news to me—I would need to find another way tostructure my daily existence.

J) She trimmed back my flowerylanguage, drew lines through my exclamation marks and argued for the value ofrestraint in expression. “John,” she almost whispered. I learned in to hearher:”I can’t hear you when you shout at me.” So I stopped shouting andbluffing, and slowly my writing improved.

K) Somewhere along the way I setaside my hopes of writing that flawless essay. But perhaps I missed somethingimportant in my mother’s lessons about creativity and perfection. Perhaps thepoint of writing the flawless essay was not to give up, but to never willinglyfinish. Whitman repeatedly reworded “Song of Myself” between 1855 and 1891.Repeatedly. We do our absolute best wiry a piece of writing, and come as closeas we can to the ideal. And, for the time being, we settle. In critique,however, we are forced to depart, to give up the perfection we thought we hadachieved for the chance of being even a little bit better. This is the lesson Itook from my mother. If perfection were possible, it would not be motivating.

46. The author was advised against theimproper use of figures of speech.

47. The author’s mother taught him avaluable lesson by pointing out lots of flaws in his seemingly perfect essay.

48. A writer should polish his writingrepeatedly so as to get closer to perfection.

49. Writers may experience periods of timein their life when they just can’t produce anything.

50. The author was not much surprised whenhis school teacher marked his essay as “flawless”.

51. Criticizing someone’s speech is said tobe easier than coming up with a better one.

52. The author looks upon his mother as hismost demanding and caring instructor.

53. The criticism the author received fromhis mother changed him as a person.

54. The author gradually improved hiswriting by avoiding fact language.

55. Constructive criticism gives an authora good start to improve his writing.
