For many people, there is only one good reason to go to an amusement park: the roller coaster. But why do People go on roller coasters?
"Where else in the world can you scream at the top of your lungs and throw your arms in the air?" Frank Farley asks. "If you did that in most other places, they'd take you to your parents and probably put you through a psychological evaluation (心理检查)." Farley is a psychologist at Temple University in Philadelphia, Pennsylvania.
Roller coasters are often attractive to kids whose lives are stressful or controlled. "Roller coasters are a way of breaking out of the humdrum (单调 ) of everyday life. You can let it all go and scream and shout or do whatever you want," Farley says. It has been proved that many adults feel the same way.
Compared with skateboarding, extreme mountain biking, and other adventure sports, riding roller coasters is safe. Parents usually don't mind when kids go on coasters. Roller coasters also have a way of bringing people together. Riders share the thrill and adventure of surviving what feels like an extreme experience.
Whether you like to ride a roller coaster may depend on your personality. Psychologists say that there is a certain type of person that naturally seeks out extreme experiences. "They enjoy things like change, variety, and intensity (强度)," says Farley. "These people are actually attracted to thrills." He describes such people as having Type-T personalities ("T" stands for thrill).
He also believes that these thrill seekers are more adventurous and creative than other people. Albert Einstein was a Type T. "If nobody liked to seek stimulation (刺激)," he argues, "the human race wouldn't be where it is today."

This morning, a Virgin Atantin 747 Jumbo Jet became the first commercial airplane to fly on biofuel. The short flight from London to Amsterdam used a blend of 20% babassu(棕榈) oil mixed with 80% conventional jet fuel.
What was really exciting about the flight was the fact that the engine did not have to be altered in any way for the biofuel to work While this is a great initial step in trying to reduce CO2(carbon-dioxide)emissions(排放)from airplanes. there are a lot of hurdles (障碍)that still need to be overcome.
First and foremost, unlike the normal fuel used to run airplanes (known as Jet A),biofuel freezes at high altitudes. Also, Jet‘A’fuel burns consistently (at the same pace),which means it provides a safe and reliable fuel for long flights--engineers are not sure if biofuel will be able to do the same.
The biggest hurdle to a full biofuel switch is our ability to be able to grow enough crops that can be converted to biofuel. There are two concerns that scientists have in this matter – the first is that the land to grow the extra crops will come from clearing more of our forests and the second is that since it competes with what we eat, the price of food will go up.
However, Richard Branson of Virgin Airlines, envisions that if biofuel starts to replace oil on a greater basis, it will be manufactured from algae（藻类）produced in sewage treatment plants, not from food sources.
Birgin Airlines is not the only one trying to look for alternative fuel sources. Earlier this year, an Airbus A380 used another alternative fuel－a man-made mix of gas-to-liquid, in one of its four engines. The flight was tested by Rolls Royce (manufacturer of jet engines), in partnership with Shell (an oil company). Rolls Royce is also working with Air New Zealand on a similar project.
While a complete switch to alternative fuel may take years, it is very encouraging to see airlines, oil companies and airplane manufacturers all coming together to try to make it happen!．Why does Virgin Airlines try to replace normal fuel with biofuel?
| A．To cut down the flight cost of the company. |
| B．To remove some hurdles for the biofuel to work. |
| C．To reduce CO2 emissions from airplanes. |
| D．To test plane engines on biofuel. |
．Which is NOT true for a full biofuel switch of airplanes?
A Biofuel cannot run for long flights.
B．Biofuel cannot work at high altitudes.
C．Man has not enough land to grow extra crops for biofuel.
D．It’s not easy for sewage treatment plants to manufacture biofuel.．One of the hurdles to be overcome for a full biofuel switch is to .
| A．alter the engine for airplanes |
| B．make biofuel burn consistently |
| C．open more land to grow more crops |
| D．develop sewage treatment plants |
．We can infer from the last paragraph that .
| A．there is a long way to go for a complete switch to alternative fuel |
| B．it won’t be long before alternative fuel comes into use |
| C．airlines, oil companies and airplane manufacturers are reliable |
| D．alternative fuel has a bright future |
．Which of the following can best serves as the title of this passage?
| A．Biofuel-Alternative Fuel Sources. |
| B．The First Commercial Flight Powered by Biofuel. |
| C．How to Reduce CO2 Emissions from Airplanes. |

It is a matter of common observation that although money income keeps going up over the years, we never seem to become richer. Prices are rising continuously. This condition is what we call inflation: the money supply is becoming inflated so that each unit of it becomes less valuable. We have got used to higher and higher rates of inflation in recent years. What could be bought twenty years ago for one pound now costs well over 2 pounds. And at present this rate of inflation seems to be rising rather than falling. If in the real world our money incomes go up at the same rate as prices do. One might think that inflation doesn’t matter. But it does ------.When money is losing value it also loses one of the qualities of a good money—stability of value. It is no longer acceptable as a store of value; and it becomes an unsuitable means of delayed payment. Nobody wants to hold a wasting possession, so people try to get rid of money as quickly as possible. Inflation therefore simply stimulates（刺激）our spending and discourages saving.From the passage we can know that inflation is a situation in which________.
| A．everyone’s incomes rise |
| B．money will hold its value |
| C．we can watch our money grow |
| D．money constantly loses its value |
．In the writer’s view, if incomes and prices rise at the same rate, ________.
| A．inflation maybe still be a problem |
| B．we have nothing to worry about |
| C．inflation is no longer a problem |
| D．we will become richer and richer |
．Under inflation people are likely to ________.
| A．go to the bank more often than usual |
| B．save more money since their incomes rise |
| C．spend money quickly rather than to save it |
| D．keep money at home instead of going to banks |
．We can conclude according to the passage that ________.
| A．the writer is a government official |
| B．the writer is worried about inflation |
| C．the writer encourages people to spend money |
| D．the writer has become richer because of inflation |
. Which of the following words is omitted at the end of the underlined sentence “But it does”?

Rowena and Billy Wrangler are model high school students. They study hard and do extremely well on achievement tests. And next year，Rowena will be attending Harvard University．Billy，her younger brother，hopes to go to Cornell．What makes Rowena and Billy different from most students is that they don't go to school．In fact，they've never been to school．Since kindergarten，they've studied at home．Like many of more than one million people who receive home schooling in the United States, they feel as if they've gotten a good education．
The home-schooling trend began in the U.S．in the 1980s with parents keeping their children out of public schools so they could provide religious education at home. Today，as the home-schooling trend continues to grow，parents are more likely to consider home schooling as an option because they believe schools don't do a very good job of teaching and are occasionally dangerous places．But can parents really do a better job?
The answer in many cases is yes．In many studies，students taught at home ranked average or above average when compared to students who went to public schools．More importantly，these students were often more self-directed and have a greater depth of knowledge．They were well prepared for academic challenges．
One such student，Robert Conrad, now a sophomore at university, claims he really learned how to study and schedule his time during his eight years of home schooling．Still, not every student is as successful as Robert．“For every home-schooling success story，there are an equal number of failures．”states Henry Lipscomb，an educational researcher．“There are just so many disadvantages that students taught at home have to overcome．”For example，they have fewer chances to get in touch with others of their own age．Consequently，they sometimes lack the usual social skills．“No matter what，though，”states Lipscomb，“home-schooling is a growing trend．I think we'll be seeing more and more of this．”Compared with other students, Rowena and Billy are most different in the fact that .
| A．they preferred to teach themselves |
| B．they do extremely well on achievement tests |
| C．they don't go to school as other teenagers |
| D．they feel they have gotten a good education |
．At first in the 1980s parents gave home-schooling to children for .
| A．better education | B．religious education | C．safety | D．good behavior |
．According to the article, what is NOT the advantage of being educated at home?
| A．Home is a safer place for children． |
| B．Students taught at home are more self-directed． |
| C．Students taught at home have a greater depth of knowledge． |

There are stories about two U．S . presidents，Andrew Jackson and Martin Van Buren，which attempt to explain the American English term OK．We don’t know if either story is true，but they are both interesting．
The first explanation is based on the fact that President Jackson had very little education．In fact，he had difficulty reading and writing．When important papers came to Jackson，he tried to read them and then had his assistants explain what they said．If he approved of a paper, he would write “all correct”on it．The problem was that he didn’t know how to spell．So what he really wrote was “ol korekt”．After a while，he shortened that term to “OK”．

My newly-rented small apartment was far away from the centre of London and it was becoming essential for me to find a job, so finally I spent a whole morning getting to town and putting my name down to be considered by London Transport for a job on the underground. They were looking for guards, not drivers. This suited me. I couldn’t drive a car but thought that I could probably guard a train, and perhaps continue to write my poems between stations. The writers Keats and Chekhov had been doctors. T.S. Eliot had worked in a bank and Wallace Stevens for an insurance company. I’d be a subway guard. I could see myself being cheerful, useful, a good man in a crisis（危机）. Obviously I’d be overqualified but I was willing to forget about that in return for a steady income and travel privileges — those being particularly welcome to someone living a long way from the city centre.
The next day I sat down, with almost a hundred other candidates, for the intelligence test. I must have done all right because after about half an hour’s wait I was sent into another room for a psychological test. This time there were only about fifty candidates. The interviewer sat at a desk. Candidates were signaled forward to occupy the seat opposite him when the previous occupant had been dismissed, after a greater or shorter time. Obviously the long interviews were the more successful ones. Some of the interviews were as short as five minutes. Mine was the only one that lasted a minute and a half.
I can remember the questions now: “Why did you leave your last job?” “Why did you leave your job before that?” “And the one before that?” I can’t recall my answers, except that they were short at first and grew progressively shorter. His closing statement, I thought, revealed（显示） a lack of sensitivity which helped to explain why as a psychologist, he had risen no higher than the underground railway. “You’ve failed the psychological test and we are unable to offer you a position.”
Failing to get that job was my low point. Or so I thought, believing that the work was easy. Actually, such jobs — being a postman is another one I still desire — demand exactly the sort of elementary yet responsible awareness that the habitual dreamer is least qualified to give. But I was still far short of full self-understanding. I was also short of cash.．The writer applied for the job chiefly because _________.
| A．he wanted to work in the centre of London |
| B．he could no longer afford to live without one |
| C．he was not interested in any other available job |
| D．he had received some suitable training |
．The writer thought he was overqualified for the job because _________.
| A．he often traveled underground | B．he had written many poems |
| C．he could deal with difficult situations | D．he had worked in a company |
．The length of his interview meant that _________.
| A．he was not going to be offered the job |
| B．he had not done well in the intelligence test |
| C．he did not like the interviewer at all |
| D．he had little work experience to talk about |
．What does the writer realize now that he did not realize then?
| A．How unpleasant ordinary jobs can be. |
| B．How difficult it is to be a poet. |
| C．How unsuitable he was for the job. |
| D．How badly he did in the interview. |
．What’s the writer’s opinion of the psychologist?
| A．He was very aggressive（有进取心的）. | B．He was unhappy with his job. |
| C．He was quite inefficient. | D．He was rather unsympathetic. |
