A car that runs on coffee is unveiled（shown to the public for the first time）today but at between 25 and 50 times the cost of running a car on petrol, the invention won’t please any motor industry accountants．
Nicknamed the Car-puccino, it has been created using a 1988 Volkswagen Scirocco bought for £400 and it was chosen because it looked like the time-traveling DeLorean in the movie Back To The Future．The car will be driven the 210 miles between Manchester and London powered only by roasted coffee granules （顆粒）．It has been built by a team from the BBC1 science programme Bang Goes The Theory and will go on display at the Big Bang science fair in Manchester to show how fuels other than traditional petrol can power vehicles．
The team calculates the Car-puccino will do three miles per kilo of ground coffee （咖啡粉） — about 56 cups of espressos （濃咖啡） per mile．The journey will use about 70 kilos of ground coffee which, at supermarket prices of between £13 and £26 a kilo depending on brand and quality, will cost between £910 and £1,820, or between 25 and 50 times the £36 cost of petrol for the journey．In total, the trip will cost 11,760 espressos, and the team will have to take ‘coffee breaks’ roughly every 30 to 45 miles to pour in more granules．They will also have to stop about every 60 miles to clean out the ‘coffee filters’ to rid them of the soot and tar which is also generated by the process．So despite a top speed of 60mph, the many stops mean the going will be slow, with the journey taking around ten hours．
Sadly, the inventors will still have to pay duty on their coffee fuel---even though tax collectors at Her Majesty’s Revenue and Custom haven’t yet worked out how much．
Nick Watson, producer of Bang Goes The Theory, said, “Coffee, like wood or coal, has some carbon content so you can use it as a fuel．The coffee needs to be very dry and in granules to allow the air to move through the pile of coffee as it burns．The brand doesn’t matter．” He said the same technology could be used to power a car on other unusual fuels, such as woodchips or nut shells, construction or agricultural waste．
小題1:Which is the right way to choose the coffee used as fuels to run the Car-puccino?
A．It should be very dry．B．The stronger, the better．
C．The smaller the granules are, the better．D．It should be of a certain brand．
小題2:What can be inferred from the passage?
A．All kinds of materials can be used as fuels．
B．The Car-puccino will be put into the market soon．
C．Nick Watson is the designer of the Car-puccino
D．Much remains to be improved for the Car-puccino．
小題3:The Car-puccino has its disadvantages EXCEPT that ________．
A．it makes a lot of noise
B．it runs at a very high cost
C．it has to stop to be refueled very often
D．it’s not good enough for long-distance journey
小題4:How much ground coffee will be used to cover a distance of 126 miles in this car?
A．About 70 kilosB．About 42 kilos．C．About 32 kilosD．About 30 kilos
小題5:Why can coffee be used as a fuel?
A．It looks like wood or coal.B．It contains some carbon content.
C．It is very cheap.D．It is much better than woodchips or nut shells.

During a state of deep relaxation, several physiological changes take place in the body: the body’s oxygen consumption is reduced; the heart beat decreases; muscle tension and sweating ease, and there is decreased sympathetic （交感的） nervous system activity．This restful state not only allows the body to repair and restore itself, but it has a calming effect on the consciousness．
How to achieve this state of relaxation, however, is a matter of opinion, and in some medical circles, a matter of controversy．A recent report by Dr．David Holmes of the University of Kansas in the journal “American psychologist” said that simply sitting in an armchair has just as many beneficial characteristics for the body as meditation （冥想） does．Researchers of other relaxation techniques disagree．These experts believe that more structured techniques, such as meditation, lead to a condition of deep relaxation．
The debate goes on, but one thing appears to be clear: the relaxation response can be reached by a number of methods, and the methods themselves are not as important as getting there．One day, one method may work best; on another day, an alternative method may be more appropriate．Once you are aware of all the methods, you can find the one that works best on you．
Some of the relaxation techniques are meditation, auto analysis and progressive muscle relaxation response．More than just sitting quietly in a chair, they have the added benefit of structure and discipline, and for these reasons appear to be more effective for most individuals．
小題1:According to the passage, which of the following statements is NOT true when a person is in a state of deep relaxation?
A．The body takes in less oxygen．
B．The heart beats less frequently．
C．Muscles become tense and the body sweats easily．
D．The consciousness becomes more or less calmed．
小題2:People seem to agree that ____．
A．sitting in an armchair benefits a person as meditation does
B．structured relaxation techniques are more beneficial for a person
C．to achieve a state of deep relaxation is possible through various means
D．what people are all struggling for is a state of deep relaxation
小題3:In the third paragraph, the phrase “getting there” means _____．
A．a(chǎn)rriving at one’s destination
B．getting what one wants most
C．finding out a suitable relaxation technique
D．reaching a state of deep relaxation
小題4:The author’s attitude toward relaxation discussed in the passage is best described as ______．
A．scepticalB．objectiveC．optimistic D．critical

Dalkoff wrote his chapter and turned it   30  ．Today he can not recall anything   31

Four words．They   34    his life.
“   35    I read those words, I had no idea of who I was or   36  I was going to be.”he said.“After reading her note, I went home and wrote a short story, something I had always been   37   of doing but never believed I could do.”

What exactly is a lie ?Is it anything we say which we know is untrue ?Or is it something more than that ?For example, suppose a friend wants to borrow some money from you. You say “I wish I could help you, but I am short of money myself.” In fact , you are not short of money but your friend is in the habit of not paying his debts and you don’t want to hurt his feelings by reminding him of this. Is this really a lie ?
Professor Jerald Jellison of the University of southern California has made a scientific study of lying. According to him, women are better liars than men, particularly when telling a “white lie”, such as when a woman at a party tells another woman that she likes her dress when she really thinks it’s terrible. However, this is only one side of the story. Other researchers say that men are more likely to tell more serious lies, such as making a promise that they have no intention of carrying out. This is the kind of lie politicians and businessmen are supposed to be particularly skilled at :the lie from which the liar hopes to profit or gain in some way.
Research has been done into the way people’s behavior changes in a number of small, unimportant ways when they lie. It has been found that if they are sitting down at the time, they tend to move about in their chairs more than usual. To the trained observer they are saying “I wish I were somewhere else now”. They also tend to touch certain parts of the face, particularly the nose. One explanation of this may be that lying causes a slight increase in blood pressure. The tip of the nose  is very sensitive to changes and the increased pressure makes it itch.
Another gesture that gives liars away is what the writer Decmond Morris in his book Man Watching calls the “mouth cover”. He says that there are several typical forms of this ,such as covering part of the mouth with the fingers, touching the upper lip or putting a finger of the hand at one side off the mouth. Such a gesture can be understood as an unconscious(未察覺的) attempt on the part of the liar to stop himself from lying.
Of course, such gestures as rubbing the nose or covering the mouth , moving about in a chair can not be taken as proof that the speaker is lying. They simply tend to happen more often in this situation. It is one gesture alone that gives the liar away but a whole number of things , and in particular the context(上下文) which the lie is told.
小題1:According to the passage, a white lie seems to be a lie ______.
A．that other people believe
B．that other people don’t believe
C．told in order not to hurt someone’s feelings
D．told in order to take advantage of someone
小題2:Research suggests that women _____.
A．a(chǎn)re better at telling less serious lies than men
B．generally lie for more than men do
C．often make promises they intend to break
D．lie at parties more often than men do
小題3:Researchers find that when a person tells lies _____.
A．his blood pressure increases measurably
B．he looks very serious
C．he is likely to make some small changes in his behavior
D．he uses his unconscious mind
小題4:The writer of the passage______.
A．hates lyingB．enjoys lyingC．often tells a lieD．tries to study about lying
小題5:Which of the following is not mentioned in the passage as a sign of lying ?
A．Touching one’s earsB．Rubbing the nose
C．Moving in a chairD．Covering the mouth

Are you a man or a mouse? When people ask this question they want to know 36  you think you are a 37  person or a coward (懦夫).

However, when you are absolutely terrified, the body can produce too much adrenalin. When this 52 , the muscles become very hard and you find you 53  at all. You are then paralyzed (使無能為力) with fear. This is 54 when we are very frightened, we sometimes say we’re “petrified”. This word comes from the Greek word “petros”, which means “stone”. We are 55  frightened that we become stonelike.

Letters to the next president
Dear Mr. President:
I would like to personally thank you for your time and concern for our great country. I would like to take a few minutes to address a few concerns that I have with the United States.
First of all, I would like to address the war. In my opinion, we should have never been involved with Iraq to the extent that we are now. I believe we should pull our troops out. However, I think there should be a time table that we follow but the time table should not be released because the enemy does not need to know when we are going to pull out. Also, the war takes out a ton of our money, which leads me to my next issue.
The economy right now, in the opinion of many Americans is the biggest issue with which we are facing right now. No one can predict what will happen one day or the next. The obvious thing to do is to put 700 billion dollars in the economy, but that bill failed and was rejected by the House of Representatives(眾議院). Instead of putting 700 billion dollars in, I think the money should be equally distributed among Americans to pay off their debts. I'm not sure if this would work, but I think it is a positive alternative we could take.
My final issue I would like to call to your attention is teacher's salaries. The high school students of today are America's future. In a way, America's future depends greatly on the high school teachers of America. Saying this, it is sad that teacher's salaries are where they are. While teachers are working harder and harder every day to teach high school students, CEO's of big companies that are driving our countries economy into the ground are getting bonuses. I'm not saying that teacher's salaries should be the same of CEO's of companies, but I do strongly believe that action should be taken to increase the salaries of teachers because they have one of the most important jobs in America - - preparing our country for the future.
Once again, thank you for your time and your effort you put in to making this great country a better place.
Sincerely, Walker
41. What's the author's attitude the Iraq War?
A. Supportive           B. Objective           C. Negative             D. Positive
42. What's true about the time of pulling the troops out?
A. We should pull the troops out without delay.
B. There is no need to have a time table to follow.
C. The public has the fight to know the time table.
D. We should keep the time secret from the enemy.
43. According to the author, the 700 billion dollars__________
A. is the biggest issue with which we are facing right now.
B. has been accepted by the House of Representatives.
C. should be equally shared among Americans
D. should be put in the economy
44. When talking about high school teachers, the author thinks that____________
A. the teachers' salaries are not high enough.
B. teacher's salaries should be as high as CEO's.
C. the teachers work harder than CEO's of companies.
D. teaching is more important than any other job in America

This brief book is aimed at high school students, but speaks to anyone learning at any stage of life．
Its formal, serious style closely matches its content, a school-masterly book on schooling．The author, W．H．Armstrong, starts with the basics: reading and writing．In his opinion, reading doesn’t just mean recognizing each word on the page; it means taking in the information, digesting it and incorporating it into oneself just as digests a sandwich and makes it a part of himself．The goal is to bring the information back to life, not just to treat it as dead facts on paper from dead trees．Reading and writing cannot be completely separated from each other; in fact, the aim of reading is to express the information you have got from the text．I’ve seen it again and again: someone who can’t express an idea after reading a text is just as ineffective as someone who hasn’t read it at all．
Only a third of the book remains after that discussion, which Armstrong devotes to specific tips for studying languages, math, science and history．He generally handles these topics thoroughly(透徹地) and equally, except for some weakness in the science and math sections and a bit too much passion(激情) regarding history．Well, he was a history teacher — if conveyed only a tenth of his passion to his students, that was a hundred times more than my history teachers ever got across．To my disappointment, in this part of the book he ignores the arts．As a matter of fact, they demand all the concentration and study that math and science do, though the study differs slightly in kind．Although it’s commonly believed that the arts can only be naturally acquired, actually, learning the arts is no more natural than learning French or mathematics．
My other comment is that the text aged．The first edition apparently dates to the 1960s — none of the references(參考文獻(xiàn))seem newer than the late 1950s．As a result, the discussion misses the entire computer age．
These are small points, though, and don’t affect the main discussion．I recommend it to any student and any teacher, including the self-taught student．
小題1:According to Armstrong, the goal of reading is to________．
A．gain knowledge and expand one’s view
B．understand the meaning between the lines
C．express ideas based on what one has read
D．get information and keep it alive in memory
小題2:The author of the passage insists that learning the arts_________．
A．requires great effortsB．demands real passion
C．is less natural than learning mathsD．is as natural as learning a language
小題3:What is a shortcoming of Armstrong’s work according to the author?
A．Some ideas are slightly contradictory．
B．There is too much discussion on studying science．
C．The style is too serious．
D．It lacks new information．
小題4:This passage can be classified as________．
A．a(chǎn)n advertisementB．a(chǎn) book review
C．a(chǎn) feature story D．a(chǎn) news report
