Steve, a twelve-year-old boy with alcoholic parents, was about to be lost forever, by the U.S. education system. He had been failing since first grade. Steve was a big boy, looking more like a teenager than a twelve year old, yet, Steve went unnoticed... until Miss White.
Miss White was a smiling, young, beautiful redhead, and Steve was in love! For the first time in his young life, he couldn’t take his eyes off his teacher; yet, still he failed. He never did his homework, and he was always in trouble with Miss White. His heart would break he was punished for failing to turn in his homework! Still, he did not study.
    In the middle of the first term of school, the entire seventh grade was tested for basic skills. Steve hurried through his tests, and continued to dream of other things.  His heart was in the woods, where he often escaped alone, trying to shut out the sights, sounds and smells of his alcoholic home. 
One day, Miss White’s impatient voice broke into his daydreams.
“Steve!” he turned to look at her.
“Pay attention!”
Steve locked his eyes on Miss White with adolescent adoration, as she began to go over the test results for the seventh grade.
“You all did pretty well,” she told the class, “except for one boy, and it breaks my heart to tell you this, but...” She hesitated.
“...The smartest boy in the seventh grade is failing my class!”
She just stared at Steve, as the class turned around for a good look. Steve dropped his eyes and carefully examined his fingertips.
After that, it was war!! Steve still wouldn’t do his homework even as the punishments became more severe.
“Just try it! ONE WEEK!” He was unmoved.
You’re smart enough! You’ll see a change!” Nothing happened.
“Give yourself a chance! Don’ give up on your life!” Nothing.
“Steve! Please! I care about you!”
Wow! Suddenly, Steve got it!! Someone cared about him? Someone, totally perfect, CARED ABOUT HIM!
Steve went home from school, thoughtful, that afternoon.  He, quickly, gathered up his camping things, this time including his schoolbooks. Determined, he headed for the woods.
The following Monday he arrived at school on time, and he waited for Miss White to enter the classroom. She walked in, all sparkle and smiles! God, she was beautiful! He expected her smile to turn on him. It did not.
Miss White, immediately, gave a quiz on the weekend homework. Steve hurried through the test, and was the first to hand in his paper. With a look of surprise, Miss White took his paper. Obviously puzzled, she began to look it over. Steve walked back to his desk, his heart beating within his chest. As he sat down, he couldn’t resist another look at the lovely woman.
Miss White’s face was in total shock! She glanced up at Steve, then down, then up. Suddenly, her face broke into a bright smile. The smartest boy in the seventh grade had just passed his first test!
From that moment nothing was the same for Steve. Life at home remained the same, but life still changed. He discovered that not only could he learn, but he was good at it! And he continued this course throughout his school life.
After high-school Steve entered the Navy, and he had a successful military career.  During his Naval career, he inspired many young people, who without him, might not have believed in themselves.
You see, it’s simple, really. A change took place within the heart of one boy, all because of one teacher, who cared.                          
1. How did Miss White’s expression change when she got Steve’s paper?   
A. satisfied —shocked —surprised —puzzled        B. puzzled —surprised —shocked —satisfied
C. surprised —puzzled —shocked —satisfied             D. surprised —shocked —satisfied —puzzled
2. Which of the following statements is NOT right according to the passage?

Do we need an “Ivy League”?
China may soon have its own “Ivy League”, with a union of top universities.
The term originally referred to an athletic conference of eight top universities in the northeastern US. The Chinese version, which was officially started in mid-October, consists of nine famous universities, including Peking, Tsinghua, Zhejiang and Fudan. The union is supposed to result in student exchange programs, recognition of academic achievements, and other joint programs.
The news of this Chinese “Ivy League” has received mixed responses from the public and press. Some negative critics have dismissed it as yet another example of the wishful copying of international practices without fully understanding them. Others say that the “Ivy League” is not necessary but that the union is a good idea, one that could promote academic development.
So what’s your opinion on a Chinese “Ivy League”? Do we need one?
Yes. Ivy League or not, nine of China’s best universities cooperating is a good thing.
These universities combining resources could create a better environment for students and for research. It could also save a lot of time and resources because it would mean fewer unnecessary investments for some of the universities.
Allowing students to move to or have exchanges with other universities could broaden their horizons, improve their social skills and create more employment opportunities. The results could be more important than lessons and achievements.
The term “Ivy League” carries a sense of academic excellence, tradition and reputation. If borrowing such a term could encourage students’ and professors’ mental state and improve Chinese higher education, then there’s no reason not to do it.
No. Universities should do some work on increasing cooperation instead of copying an “Ivy League” model.
Many Chinese universities already have such cooperation with each other. If this cooperation were associated with the “Ivy League”, it would just distract (分散) attention and resources and have a negative effect.
These Chinese universities are all state-run and most get their funding from the government. They’re quite similar to each other in many ways and more cooperation wouldn’t bring about as much potential ability as between , say, public and private, or Chinese and foreign universities.
China should find its own way to develop world-class universities instead of by copying some foreign practices. We have our own unique conditions and foreign lessons often don’t apply well here.

Domestic airline passengers will be able to make phone calls and send e-mails from the sky from next year, a local carrier has said.
Shenzhen Airlines said on Monday it has signed an agreement with Geneva-based On-Air to provide passengers with in-flight communications services on all its planes by the end of 2009. The service will be introduced on three aircraft ahead of the 2008 Olympics, on two routes----from Shenzhen to Beijing and Shenzhen to Shanghai, the airline said.
Passengers will be able to use their own electronic devices to send e-mails and short messages, make calls and surf the Internet, it said. The service is expected to be of particular interest to business travelers.
According to a survey at the end of last year, China had 4.55 million mobile-phone subscribers. Ninety-three percent of those polled said they wished they could send and receive e-mails and messages while on a plane.
Despite the introduction of the new service, passengers will still be prevented from using their cell phones and laptops when the plane is taking off and landing, or flying at less than 3,000 m above sea level, the official said.
The official said the new service would not lead to an increase in ticket prices, but users of Chinese mobile-phone services will be charged the international roaming rate for any calls made from the sky.
Shenzhen Airlines is the first Chinese carrier to provide such in-flight communications services. Its president, Li Kun, said installing the facilities will cost 4.5 million yuan ($596,000) per aircraft.  However, the project still needs to be approved by the Civil Aviation Administration of China, a source said.

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.

Another important 30 is how much each worker 31 to the product he is making . In most factories the worker 32 only one small part of the product . Some car factories are now 33 with having many small production lines rather than one large one , so that each worker contributes more to the production of the cars on his 34 . It would seem that not only is degree of worker contribution an important factor 35 it is one we can do something about .
To what 36 does more money lead to greater productivity ? The workers themselves certainly think this is 37 . But perhaps they want more money only because the work they do is so boring , 38 just lets them enjoy their spare time more . A 39 argument may explain demands for shorter working hours . Perhaps if we 40 making their jobs more interesting , they will neither want more money , nor will shorter working hours be so important to the .

How Much to Tip
You’re out to dinner . The food is delicious and the service is fine . You decide to leave a big fat tip . Why ? The answer may not be as simple as you think .Tipping , psychologists have found , is not just about service . Instead , studies have shown that tipping can be affected by psychological reactions to a series of different factors from the waiter’s choice of words , to how they carry themselves while taking orders , to the bill’s total . Even how much waiters remind customers of themselves can determine how much change they pocket by the end of the night .“Studies before have shown that mimicry brings into positive feelings for the mimicker ,”wrote Rick van Baaren , a social psychology professor . “ There studies show that people who are being mimicked become more generous toward the person who mimics thorn .”
So Rick van Baaren divided 59 waiters into two groups . He requested that half serve with a phrase such as “ Coming up ! ” Those in the other half were instructed to repeat to orders and preferences back to the customers . Rick van Baaren then compared their take home . The results were clear-it plays to mimic your customers . The copycat waiters earned almost double the amount of tips to the other group .
Leonard Green and Joe Myerson , psychologists at Washington University in St . Louis found the generosity of a tipper may be limited by his bill . After research on the 1,000 tips left for waiters , cab drivers , hair stylists , they found tip percentages in these three areas dropped as customers’bills went up . In fact , tip percentages appear to plateau when bills topped $100 and a bill for $200 made the worker gain no bigger percentage tip than a hill for $100 .
“That’s also a point of tipping ,” Green says . “ You have to give a little extra to the cab driver for being there to pack you up and something to the waiter for being there to serve you . If they weren’t there you’d never get any service . So part of the idea of a tip is for just being there .”
1.How many factors affecting the customers’ tipping are mentioned in the passage ?
A.1                              B.2                              C.3                              D.4
2.These studies show that ______.
A.tipping can be affected by physical reactions to many different waiter’s factors
B.people who are being mimicked usually tip less to the person who mimics them

Farmers use different kinds of soil conservation methods to protect their land from damage by farming and the forces of nature . One important form of soil conservation is the use of windbreaks . Windbreaks are barriers formed by trees and other plants with many leaves . Farmers plant them in lines around their fields .
Windbreaks stop the wind from blowing soil away . They also keep the wind from destroying or damaging crops . They are very important for growing grains , such as wheat . There have been studies done on windbreaks in parts of West Africa , for example . These found that grain harvests can be twenty percent higher in fields protected by windbreaks compared to fields without such protection .
However , windbreaks seem to work best when they allow a little wind to pass through . If the wall of trees and plants stops wind completely , then violent air motions will take place close to the ground . These motions will lift soil into the air where it will be blown away .
For this reason , a windbreaks is best if it has only sixty to eighty percent of the trees and plants needed to make a solid line . An easy role to remember is that windbreaks can protect areas up to ten times the height of the tallest trees in the windbreaks .
These should be at least two lines in each windbreak . One line should be large trees . The second line , right next to it , can be shorter trees and other plants with leaves . Locally grown trees and plants are best for windbreaks .
