The latest research suggests that the key factor separating geniuses from the merely accomplished is not I.Q., a generally bad predictor of success. Instead, it’s purposeful practice. Top performers spend more hours practising their craft. It you wanted to picture how a typical genius might develop, you’d take a girl who possessed a slightly above average language ability. It wouldn’t have to be a big talent, just enough so that she might gain some sense of distinction. Then you would want her to meet, say, a novelist, who coincidentally shared some similar qualities. Maybe the writer was from the same town, had the same family background, or shared the same birthday.

 This contact would give the girl a vision of her future self. It would hive her some idea of a fascinating circle who might someday join. It would also help if one of her parents died when she was 12, giving her a strong sense of insecurity and fuelling a desperate need for success. Armed with this ambition, she would read novels and life stories of writers without end. This would give her a primary knowledge of her field. She’s be able to see new writing in deeper ways and quickly understand its inner workings.

 Then she would practise writing. Her practice would be slow, painstaking and error-focused. By practising in this way, he delays the automatizing process. Her mind wants to turn conscious, newly learned skills into unconscious. Automatically performed skills. By practising slowly, by breaking skills down into tiny parts and repeating, she forces the brain to internalize a better pattern of performance. Then she would find an adviser who would provide a constant stream of feedback, viewing her performance form the outside, correcting the smallest errors, pushing her to take on tougher challenges. By now she is redoing problems—how do I get characters into a room—dozens and dozens of times. She is establishing habits of thought she can call upon in order to understand or solve future problems.

 The primary quality our young writer possesses is not some mysterious genius. It’s the ability to develop a purposeful, laborious and boring practice routine; the latest research takes some of the magic out of great achievement. But it underlines a fact that is often neglected. Public discussion is affected by genetics and what we’re “hard-wired” to do. And it’s true that genes play a role in our capabilities. But the brain is also very plastic. We construct ourselves through behaviour.

The passage mainly deals with________.

A. the function of I.Q. in cultivating a writer

B. the relationship between genius and success

C. the decisive factor in making a genius

D. the way of gaining some sense of distinction

By reading novels and writers’ stories, the girl could________.

A. come to understand the inner structure of writing

B. join a fascinating circle of writers someday

C. share with a novelist her likes and dislikes

D. learn from the living examples to establish a sense of security

In the girl’s long painstaking training process, ________.

 A. her adviser forms a primary challenging force to her success.

 B. her writing turns into an automatic pattern of performance

 C. she acquires the magic of some great achievement

 D. she comes to realize she is “hard-wired” to write

What can be concluded from the passage?

 A. A fuelling ambition plays a leading role in one’s success

 B. A responsible adviser is more important than the knowledge of writing.

 C. As to the growth of a genius, I.Q. Doesn’t matter, but just his|her effort.

 D. What really matters is what you do rather then who you are.

         Over the past century, all kinds of unfairness and discrimination(歧視) have been made illegal. But one popular form continues to exist, that is alphabetism (字母排序法). This, for those as yet unaware of such a disadvantage, refers to discrimination against those whose surnames (姓氏) begin with a letter in the lower half of the alphabet.

         It has long been known that the cars of a taxi firm called AAAA have a big advantage over Zodiac cars when customers look through their phone directories. Less well known is the advantage that Adam Abbot has in life over Zoe Zysman. English names are fairly spread between the halves of the alphabet. Yet a quite large number of top people have surnames beginning with letters between A and K.

         Thus the American presidents and vice-presidents have surnames starting with B and C separately and 26 of those before George Bush took office (including his father) had surnames in the first half of the alphabet against just 16 in the second half. Even more striking, six of the seven heads of government of the G7 rich countries are alphabetically advantaged (Berlusconi, Blair, Bush, Chirac, Chretien and Koizumi ). The world’s three top central bankers (Greenspan, Duisenberg and Hayami) are all close to the top of the alphabet, even if one of them really uses Japanese characters. The same case are the world’s five richest men (Gates, Buffet and so on).

         Can this merely happen by chance? At the start of the first year in primary school, teachers seat pupils alphabetically from the front, to make it easier to remember their names. So shortsighted Zysman gets stuck in the back row, and is seldom asked the improving questions by those teachers. At that time the alphabetically disadvantaged may think they have had a lucky escape. Yet the result may be worse qualifications, because they get less attention, as well as less confidence in speaking publicly.

         The unfairness continues. At university graduation parties, the ABCs proudly get their awards first. However, by the time they reach the Zysmans most people are a little tired. Lists of job interviews and conference speakers and attendees all tend to be drawn up alphabetically, and their readers lose interest as they plough through them.

1. What does the author intend to show with AAAA cars and Zodiac cars?

         A. An example of competition of two kinds of cars.         B. Some advantages of AAAA cars in the taxi firm.

         C. An example of unfairness caused by alphabetism.     D. Some disadvantages of Zodiac cars in the taxi firm.

2. What can we infer from the first three paragraphs?

         A. The alphabet is to blame for the failure of Zoe Zysman.

         B. In both East and West, names are important to success.

         C. Customers often pay a lot of attention to companies’ names.

         D. The discrimination in alphabetism can be found in many areas.

3. The fourth paragraph suggests that         .

         A. alphabetically disadvantaged students often escape from class

         B. teachers should pay equal attention to all their students

         C. questions are often put to the more intelligent students

         D. students should be seated according to their eyesight

4. Which of the following is true according to the passage?

         A. VIPs in the western world gain a great deal from alphabetism.

         B. People with surnames beginning with N to Z are often ill – treated.

         C. Putting things alphabetically may lead to unintentional unfairness.

         D. The movement to get rid of alphabetism still has a long way to go.

第一節(jié)任務(wù)型閱讀 (共10小題;每小題1分,滿分10分)

認(rèn)真閱讀下列短文,并根據(jù)所讀內(nèi)容在文章后表格中的空格里填入一個(gè)最恰當(dāng)?shù)膯卧~。

注意:每個(gè)空格只填1個(gè)單詞。I used to be the messiest person alive. Over the years, through watching others and by trial and error, I have finally found ways to come up with plans, organize them and follow through with them.

Make an outline of everything you need to have and do to make your plan happen. Make a list of all of the steps that need to be accomplished and think about what needs to be done.

Detail everything thoroughly and read over it so you can start coming up with some mental solutions of how to carry out your plans.

You should ensure that if for some reason way one doesn’t work, you have way two and way three to lean back on. Therefore, different ways are needed at hand. It’s just a matter of being organized. Chances are that there is always more than one way of doing things, and chances are that if one of those ways doesn’t work, one of the other ones will.

Committing yourself to finishing at least part if not all of your plan at once is also necessary. It will show that you not only have initiative to get things rolling, but that you are interested in the results obtained with making the move to get everything done.

If you make a commitment to finish before a specific time, make sure that you carry that out, and be sure to do everything in the way you said you would, within the time-frame you set for yourself.

Don’t try to tackle more things all at a time. All that does is delay your progress, distract you and make you lose your interest, motivation and energy.

Carrying out an effective plan requires being as organized as possible. You will only achieve this by sticking to the order of the plan and not deviating or trying to do more at a time.

Last but not least, you should never abandon things mid-project. It will only annoy everyone around you including yourself. Unfinished plans are a waste of time, energy and, in some cases, even money. 

So, don’t be afraid of organization. The older we get, the more necessary it becomes to have the skills necessary to follow through with confidence and to be able to carry through plans in an organized and manageable way. It pays to be organized, after all.
