All too often, a choice that seems sustainable(可持续的)turns out on closer examination to be problematic. Probably the best example is the rush to produce ethanol(乙醇) for fuel from corn. Corn is a renewable resource —you can harvest it and grow more, almost limitlessly. So replacing gas with corn ethanol seems like a great idea. 
One might get a bit more energy out of the ethanol than that used to make it, which could still make ethanol more sustainable than gas generally, but that’s not the end of the problem. Using corn to make ethanol means less corn is left to feed animals and people, which drives up the cost of food. That result leads to turning the fallow land –including, in some cases, rain forest in places such as Brazil—into farmland, which in turn gives off lots of carbon dioxide (CO) into the air. Finally, over many years, the energy benefit from burning ethanol would make up for the forest loss. But by then, climate change would have progressed so far that it might not help.
You cannot really declare any practice “sustainable” until you have done a complete life-cycle analysis of its environmental(环境的) costs. Even then, technology and public keep developing, and that development can lead to unforeseen and undesired results. The admirable goal of living sustainably requires plenty of thought on an ongoing basis.
What might directly cause the loss of the forest according to the text?

A.The growing demand for energy to make ethanol
B.The increasing carbon dioxide in the air
C.The greater need for farmland
D.The big change in weather.

The underlined word “it” in the second paragraph refers to “           ” 

A.the energy benefit B.the forest loss
C.climate change D.burning ethanol

The author thinks that replacing gas with corn ethanol is           . 

A.impractical B.acceptable C.admirable D.useless

What does the author mainly discuss in the text? 

A.Technology B.Sustainability
C.Ethanol energy D.Environmental protection

One of the most difficult questions to answer is how much a job is worth. We naturally expect that a doctor’s salary will be higher than a bus conductor’s wage. But the question becomes much more difficult to answer when we compare, say, a miner with an engineer, or an unskilled man working on an oil-rig(钻油机) in the North Sea with a teacher in a secondary school. What the doctor, the engineer and teacher have is many years of training in order to obtain the necessary qualifications for their professions. We feel instinctively that these skills and these years, when they were studying instead of earning money, should be rewarded. At the same time we recognize that the work of the miner and the oil-rig laborer is both hard and dangerous, and that they must be highly paid for the risks they take.
Another factor we must take into consideration is how socially useful a man’s work is, regardless of the talents he may bring to it. Most people would agree that looking after the sick or teaching children is more important than, say, selling secondhand cars or improving the taste of toothpaste by adding a red stripe to it. Yet it is almost certain that the used car salesman earns more than the nurse, and that research chemist earns more than the school teacher.
Indeed, this whole question of just rewards can be turned on its head. You can argue that a man who does a job which brings him personal satisfaction is already receiving part of his reward in the form of a so-called “psychic(精神的) wage”, and that it is the man with the boring, repetitive job who needs more money to make up for the soul-destroying monotony(单调) of his work. It is significant that that those jobs which are traditionally regarded as “vocations” --- nursing, teaching and the Church, for example --- continue to be poorly paid, while others, such as those in the world of sport or entertainment, carry financial rewards out of all proportion to their social worth.
Although the amount of money that people earn is in reality largely determined by market forces, this should not prevent us from seeking some way to decide what is the right pay for the job. A starting point for such an investigation would be to try to decide the ratio which ought to exist between the highest and the lowest paid. The picture is made more complicate by two factors: firstly by the “social wage”, i.e, the welfare benefits which every citizen receives; and secondly, by the taxation system, which is often used as an instrument of social justice by taxing high incomes at a very high rate indeed. Allowing for these two things, most countries now regard a ratio of 7:1 as socially acceptable. If it is less, the highly-qualified people carrying heavy responsibilities become disillusioned, and might even end up by emigration(移民) (the so-called “brain-drain” is an evidence that this can happen). If it is more, the gap between rich and poor will be so great that it will lead social tensions and ultimately to violence.
74. The professional man, such as the doctor, should be well paid because ______.
A. he has spent several years learning how to do his job
B. his work involves much great intelligence than, say, a bus conductor’s
C. he has to work much harder than most other people
D. he knows more than other people about his subject
75. The “brain-drain” is an evidence that ______.
A. well-educated people are prepared to emigrate whenever they can get a better paid job
B. people with jobs or responsibility expect to be highly paid
C. high taxation is a useful and effective instrument of social justice
D. the poor are generally more patriotic(爱国的) than the rich
76. As far as rewarding people for their work is concerned, the writer, believes that ______.
A. we should pay for socially-useful work, regardless of the person’s talent
B. we should pay people according to their talents
C. market forces will determine how much a person is paid
D. qualified people should be the highest paid
77. The argument of the “psychic wage” is used to explain why ______.
A. people who do socially important work are not always well paid
B. people who do monotonous jobs are highly paid
C. you should not try to compare the pay of different professions
D. some professional people are paid more than others

Generations of children who sat through endless lessons of "chalk and talk" in front of a bossy teacher could take some relief. But the "chalk and talk" method helped them achieve better exam results. Modern classroom techniques may make school days a great deal happier, but contentment(满意) is not the road to success in examinations, according to university researchers.
Their three-year study, monitoring the progress of 2,000 teenagers, tried to measure the influence of the "boredom factor" in 17 selected schools in the north of England. The researchers also found that the old-fashioned approach of teachers ordering pupils about is still alive and producing results. Their conclusions were welcomed yesterday by educationists who were worried by the shift to less formal lessons.
The pupils in the latest study were asked to award teachers marks to measure how frequently they followed or ignored today's fashion for "child-centred" education. A five-point scale was given to spot the teachers who always told them what they should know and what to write down. "It was significant and not something you would get by chance or accident. Certainly, when you compare the pupil's interest and attitude to school, there is a quite definite and highly significant difference," one of the researchers said. But the rankings were turned upside down when the team of four researchers looked at how the children did in examinations. The sort of methods now frowned upon (不认同) actually improve the final grades.
The researchers said, "There is nothing wrong with old-fashioned, didactic(说教式的) teaching in the right place, even if it isn't the flavor at the moment." However, he insisted the best teachers had always mixed the two techniques to match the needs of pupils, although certain examinations forced some to concentrate more on dictation and learning by rote(死记硬背).
71. We can infer from Paragraph 3 that ______.
A. child-centred education promotes friendship among children
B. the research findings are not significant enough for a conclusion
C. those who show greater interest in school did better in exams
D. those who don't show much interest in school may turn out to score higher in tests
72. The researchers suggest that ______.
A. more old methods be used in teaching
B. students be taught how to score high in exams
C. dictation be used as one of the best teaching methods
D. old and new methods be used together
73. The best title for this text would be ______.
A. The Examination-based Teaching B. Rote Learning Was the Winner
C. The Problem of Child-centred Education D. The Problem of the Traditional Method

D
To what degree can a computer achieve intelligence (智力)? The answer to this question may lie in a newly-developed US computer program called Smarter Child and the Internet.
If you ran into Smarter Child online , you would be surprised at this kid’s huge memory.It can recite many facts. For example , Smarter Child knows every baseball player in every team this season.
He knows every word in the dictionary and the weather in every major city areas across the US.However , if you ask Smarter Child other questions , you get stranger answers.A question about Smarter Child’s age returns. “One year, 11 days, 16 hours, 7 minutes, and 47 seconds!” Asking where he lives gets , “In a clean room in a high-tech building in California.”
Smarter Child uses the vast information on the World Wide Web as his memory bank.To answer questions about spelling , for instance , Smarter Child goes to American Heritage Dictionary online.For the weather , he visits www.intellicast.com.
Some scientists believe that by joining the many systems of the Internet , an artificial being with the combined knowledge of , say , Albert Einstein, Richard Nixon and Britney Spears could be born.However if Smarter Child wants to think and learn on his own like the boy-computer David in the movie A.I., Artificial Intelligence , he must overcome two problems.
The first is that computers find it difficult to read web pages because the files are labeled in different ways.That’s why programmers need to tell Smarter Child where to look for the weather.It would be a much more difficult task to let him find it himself.
Another problem is that while Smarter Child can process (处理) information more exactly and faster than any human , he lacks common sense—a basic grounding of knowledge that is obvious to any young child.
67.From the text we can infer that www.intellicast.com is a website___________.
A.which is specially designed to help Smarter Child
B.where we people can find Smarter Child
C.where weather forecasts are made
D.which is about artificial intelligence
68.It is probably most difficult for Smarter Child to_______.
A.tell us how to spell a difficult word
B.tell us how the American government is run
C.provide us with a famous poem by Shakespeare
D.learn how to tell right behaviors from wrong ones。
69.Which of the following is TRUE according to the text?
A.Smart Child has his own memory bank big enough for all kinds of information.
B.A.I.Artificial Intelligence is probably the name of a film about a boy-computer.
C.Smart Child can recognize different files and find information needed on his own.
D.We have similar product now which has the knowledge of Einstein , Nixon and Spears.
70.Which of the following is the best title for the passage?
A.A New Web Child B.Smarter Child
C.The Future of Internet D.Intelligence Development

Everyone’s at it, even my neighbors. I thought I might be the only person left in the world who hadn’t done an eBay deal. So, I decided to try my hand at online auction(网上拍卖).
Buying for Beginners
Sign up on www. eBay. co. uk. Most items (e.g. tables, computers and books) ready for auction will come with a picture and a short description; others may be marked with “Buy It Now ” and have a fixed price. You can buy these right away.
If the item is being auctioned, you offer the highest price you are prepared to pay and eBay bids (出价) for you. The bid will be increased little by little until it goes beyond your highest bid, then you are emailed and asked if you would like to bid again. Auctions last up to 10 days and when they finish, you get an email telling you whether you have won the item.
How to Pay
Sellers decide how they would like to be paid and you need to check this before placing a bid as you might not want to post a check or postal orders. The easiest way is through PayPal, an online payment system that takes the money away from your credit card.
Selling Made Simple
If you plan to sell on eBay, it helps to include a picture of the item. I followed my friends’ advice and put up the items I wanted to sell for a 10-day auction, starting on a Thursday. This way buyers had two weekends to bid.
The big Things in Life
It’s easy to post a small item, but furniture is a big part of eBay and this has to be collectively sent by deliverymen. Check the ways of delivery before you bid.
64. What is the passage mainly about?
A. How to make payment online. B. Ways of making delivery online.
C. How to use an online-auction system. D. Advantages of an online auction system.
65. After bidding for an item, a buyer ________.
A. has chances to make higher bids B. will get what he wants in ten days
C. should make payment immediately D. may check its picture and description
66. The easiest way of making payment mentioned in the passage is ________.
A. through a local banking system B. by sending the money to the seller
C. through an online payment system D. by paying the deliveryman directly

B
“How are you?” is a nice question. It’s a friendly way that people in the United States greet each other. But “How are you?” is also a very unusual question. It’s a question that often doesn’t have an answer. The person who asks “How are you?” hopes to hear the answer “Fine.”, even if the person’s friend isn’t fine. The reason is that “How are you?” isn’t really a question and “Fine.” isn’t really an answer. They are simply other ways of saying “Hello!” or “Hi!”.
Sometimes, people also don’t say exactly what they mean. For example, when someone asks, “Do you agree?”, the other person might be thinking, “No, I disagree. I think you’re wrong …” But it isn’t very polite to disagree strongly, so the other person might say “I’m not sure …”. It’s a nice way to say that you don’t agree with someone.
People also don’t say exactly what they are thinking when they finish talking with other people. For example, many talks over the phone finish when one person says “I’ve to go now.” Often, the person who wants to hang up gives an excuse, “Someone is at the door.” “Something is burning on the stove.” The excuses might be real, or it might not. Perhaps the person who wants to hang up simply doesn’t want to talk any more, but it isn’t polite to say that. The excuse is more polite, and it doesn’t hurt the other person.
When they are greeting each other, talking about an idea, or finishing a talk, people often don’t say exactly what they are thinking. It’s an important way that people try to be nice to each other, and it’s also a part of the game of language.
60. When a person in the United States asks “How are you?”, he or she wants to hear “___________”
A. How are you? B. Hello! C. I don’t know. D. Fine.
61. When a person wants to disagree with someone, it is polite to say “___________”
A. You’re wrong. I disagree. B. I’m not sure.
C. I’m sure I disagree. D. No, I disagree.
62. When a person says “I’ve to go now. Someone is at the door.”, he or she may be __________.
A. giving an excuse B. hurting someone’s feeling
C. talking to a person at the door D. going to another place
63. One of the rules of the game of language is probably “_________”
A. Always say what you mean. B. Don’t disagree with people.
C. Never say exactly what you’re thinking. D. Be polite.
