At a laboratory in Germany ,volunteers slide into a machine and perform simple tasks, such as deciding whether to add or subtract two numbers , or choosing which of two buttons to press.
They have no idea that scientists in the next room are trying to read their minds-using a brain scan to figure out their intention before it is turned into action.
In the past ,scientists had been able to detect decisions about making physical movements before those movements appeared .But researchers at Berlin's Bernstein Center for Computational Neuroscience claim they have now , for the first time ,identified people's decisions about how they would later do a high-level mental activity-in this case ,adding versus subtracting.
While still in its initial stages ,the techniques may eventually have wide-ranging implications for everything from criminal questioning to airline security checks.
The research,which began in July 2005,has been of limited scope:only 21 people have been tested so far.And the 71 percent accuracy rate is only about 20 percent more successful than random selection.
Still ,the research conducted at the Max Planck Institute for Human Cognitive and Brain Sciences in Leipzig ,about 150 kilometers southwest of Berlin ,has been generating strong interest in the scientific community.
In one study ,participants were told to decide whether to add or subtract two numbers a few seconds before the numbers were flashed on a screen . Meanwhile ,a computer captured images of their brain waves to predict the subject's decision-with one pattern suggesting addition, and another subtraction.
The team ,headed by Haynes ,began its research by trying to identify which part of the mind was storing intentions. They discovered it was found in the prefrontal cortex region by scanning the brain to look for bursts of activity when subjects were given choices.
Then they went about studying which type of patterns were associated with different intentions.
"If you knew which thought signatures to look for ,you could theoretically predict in more detail what people were going to do in the future," said Haynes.
75.Which of the following is true about the experiment at the laboratory?
A.The volunteers are asked to perform very complicated tasks.
B.Everything was explained to the volunteers before the experiment.
C.The volunteers cannot see the scientists while performing the tasks.
D.The volunteers started the experiment by pressing one of the two buttons.
76.Which of the following demonstrates the major breakthrough made by the German scientists?
A.By studying the subjects' brain waves , they know what physical movements they'll make.
B.By studying the subjects' brain waves, they know what mental task they'll perform.
C.By studying criminals' brain waves ,they can help find out whether they are lying or not.
D.By studying passengers' brain waves ,they can help find out who intends to make trouble.
77.In the research which began in July 2005 only______subjects' brains were scanned and the accuracy rate was______.
A.21; 20%      B.71;20%       C.21;71%       D.20;71%
78.The group of scientists in Leiqzig were doing______what the group in Berlin were doing.
A.similar research to                  B.better research than
C.completely different things from        D.a less satisfactory job than
79.The term thought signatures in the last paragraph refers to______.
A.the subjects' intentions       B.the subjects' physical movements
C.parts of the human brain    D.the human brain wave patterns
80.From the information in the passage, it can be concluded that in the future______.
A.the intentions of people can be predicted accurately
B.it's impossible to predict accurately the intentions of people
C.no one in the world will dare to tell lies to other people

Barcelona December 22,2007.
Spain’s “El Gordo,” the word’s biggest lottery (彩票), gave out 2.2 billion euros (歐元) (1.6 billion pounds) in Christmas prizes on Saturday.
El Gordo, Spanish for "The Fat One", is designed so that as many people as possible across Spain get a festive windfall. The top prize this year was 3 million euros -- going to the series of tickets with the magic number 06381.
Because the tickets are sold in a series of 10, only those who paid 200 euros for the whole strip get the full prize.
The biggest share of winning tickets was bought by people in the town of Nava, in the north-western Asturias region.
The draw lasts three-and-a-half hours and is carried live on national television with children from the San Ildefonso school, a former orphanage in Madrid, in turn chanting the winning numbers and the amount won.
Lotteries have two centuries of history in Spain. The country spent 2.87 billion euros on the lottery -- 5.7 percent more than last year. Seventy percent is paid out in prizes. Most of the rest goes in costs. Eight out of ten Spaniards bought tickets for the lottery, spending on average 64 euros. Spaniards often choose lottery numbers matching significant dates although there was no particular favourite in 2007. In 2006, one of the most sought-after series was 22105, the date on which Fernando Alonso became Formula 1 world champion for the second year running.
小題1:The underlined word “windfall” in paragraph two probably means         .
A．fat giftB．unexpected fortune
C．big feastD．wind and snow
小題2:Who is likely to win the full prize in El Gordo?
A．People who paid 200 euros for the wole group of series.
B．People who bough tickets with the magic number 06381.
C．People who lived in a town in the northwestern Asturias.
D．People who chose lottery numbers matching Alonso’s date.
小題3:According to the text, children from the San Ildefonso School in Madrid will         .
A．host the draw of lottery live on TV
B．offer a show of three – and – a – half hours
C．perform with the lottery draw as Christmas celebration
D．help make some declarations for the draw as invited guests
小題4:What can we learn about the history of lotteries in Spain?
A．Most of the money people spent on lotteries goes in the cost.
B．The majority of Spaniards have the experience of buying lotteries.
C．Lottery numbers matching significant dates help people win every year.
D．As the biggest in the world, Spanish lotteries have a history of two centuries.

The truth in other words
A blind boy sat on the steps of a building with a hat by his feet. He held up a sign which said: “I am blind, please help.” There were only a few coins in the hat.
A man was walking by. He took a few coins from his pocket and dropped them into the hat. He then took the sign, turned it around, and wrote some words. He put the sign back so that everyone who walked by would see the new words.
Soon the hat began to fill up. A lot more people were giving money to the blind boy. That afternoon the man who had changed the sign came to see how things were. The boy recognized his footsteps and asked: “Were you the one who changed my sign this morning? What did you write?”
The man said: “I only wrote the truth. I said what you said but in a different way.”
What he had written was : “Today is a beautiful day but I cannot see it.”
Do you think the first sign and the second sign were saying the same thing?
Of course both signs told people the boy was blind. But the first sign simply told people to help by putting some money in the hat. The second sign told people that they were able to enjoy the day, but the boy could not enjoy it because he was blind.             The first sign simply said the boy was blind. The second sign told people they were so lucky that they were not blind.
There are at least two lessons we can learn from this simple story.
The first is : Be thankful for what you have. Someone else has less. Help where you can.
The second is: Be creative. Think differently. There is always a better way!
56. The man wrote some words on one side of the boy’s sign because       .
A. he thought that the blind boy didn’t know how to write
B. he wanted to prove that the boy was really blind
C. he thought that the boy couldn’t get any money
D. he wanted to help the poor blind boy
57. The changed sign worked better than the original one because        .
A. the original sign told people to do things, which people don’t like
B. the second sign made people see their health as a gift, which made them willing to help
C. the original sign pointed out a kind of suffering that people don’t care about at all
D. the second sign drew people’s attention to another problem the boy had
58. We can learn from the story that the man who rewrote the sign was        .
A. creative      B. patient       C. funny      D. curious
59. The story shows us that        .
A. thinking in a different way can get us out of trouble
B. learning to be thankful for what we have may help us to live happier lives
C. creative thinking may bring us better results
D. being kind and respectful will encourage blind people to help themselves

第三部分：閱讀理解（共20小題；每小題2分,滿分40分）
When Chato's barking didn't stir Jerrica Seals, the recently adopted dog triednibbling on the teenager's leg, to get the girl out of her burning house.
No one was hurt. Fort Myers firefighters responded at about 7 a.m.
Five people lived in the Garcia home. That was neighbor Janice Hamilton's main concern when she looked out of her window Friday and saw the flames. "I just threw my pants on to run outside and make sure  they knew how many people lived there," Hamilton said. "It was scary."
"Seals called me screaming," said Leticia Vega, 36, the sister of Seal's boyfriend, Javier Garcia, 23, who owns the home. "She said the dog woke her up barking, jumped on the bed and bit her on the leg."
It is said that Garcia's brother brought Chato home several weeks ago after the animal wandered onto a Lehigh Acres construction site. Since then, Vega said, Chato had been mostly quiet－until it mattered. "He doesn't usually bark." Vega said. "He's real friendly."
According to deputy fire chief Steve Clyatt, possibly the fire started because of an inadequate extension cord used on a window air conditioner. More than half of the home was burned down. There was extensive smoke and water damage in the remainder of the structure. Estimates for repair costs were unavailable. "I'd say it's unlikely they will recover this, but I've been surprised before," Clyatt said.
61.Which of the following would be the best title for the passage?
A. Janice Hamilton Helps Save Neighbors
B. Firefighters Put Out House Fire
C. Dogs Saves Teen Girl From House Fire
D. Family Needs Help Due To House Fire
62.The underlined word "they" in the third paragraph most probably refers to________.
A. other neighbors         B. Hamilton family members
C. Vega and her brother Garcia     D. the firefighters
63.By saying "I'd say it's unlikely they will recover this, but I've been surprised before." in the last paragraph, Clyatt means________.
A. it's a wonder that Seals survived the fire  B. the house was badly damaged
C. such a bad fire was seldom seen      D. Chato is a very clever dog
64.According to the passage, which of the following is NOT mentioned?
A. The person who called the firefighters.    B. The possible cause of the accident.
C. The relationship between Seals and Garcia.     D. The owner of the house.

An earthquake is caused by a sudden slip on a fault, or fracture, in the earth's surface. The tectonic plates on the surface are always slowly moving, but they get stuck at their edges because of friction. When the stress on the edge overcomes the friction, there is an earthquake that releases energy in waves that travel through the earth's crust and create the shaking we feel.
An earthquake's degree is a measured value of its size and is the same no matter where you are, or how strong or weak the shaking was in different locations. An earthquake's intensity is a measure of the shaking it creates, and varies with location.
A degree of 8 or higher defines a “great” earthquake; 7 to 7.9 is considered “major”; 6 to 6.9 is “strong”;5 to 5.9 is “moderate”; 4 to 4.9 is “l(fā)ight”; 3 to 3.9 is "minor"; and less than 3 is “micro.”
Experts have said that a million people died in earthquakes in the 20th century ­and that this century might see 10 times as many deaths, with as many as a million killed in a single quake. That is, unless major efforts are made to fortify the world’s growing cities, which are expected to be homes to billions of added residents.
Even though the rate of earthquakes over time seems to be more or less unchanging, the world's population explosion means that more people are moving into quake zones, which are often near coasts. The result, the experts say, is the prospect of continuing trauma.
“It is inevitable,” Klaus H. Jacob, an earthquake expert at Lamont-Doherty, the earth sciences research center of Columbia University, said at the end of the last century. “More and more people, and more and more buildings, are  at stake  . As the world gets more populous and richer, allowing a more built-up environment, higher buildings and all the infrastructure that supports our civilization, communications and the like, the risk goes up.”
63. We can feel the earthquake because               
A. the plates are always moving.     
B. the stress overcomes the friction.
C. the plates get stuck.  
D. the waves in which energy is released travel through the earth’s crust.
64. a degree of 8.2 is thought             
A. a  “moderate” earthquake.         B. a “major” earthquake .
C. a “strong” earthquake.             D. a “great” earthquake.
65.  Experts have said that                
A. a billion people died in earthquakes in the 20th century.
B. ten times as many deaths will be seen by this century.
C. a million people will be killed in a single earthquake this century.
D. if we don’t take measures, something worse may happen.
66. The underlined expression probably means           .
A. endangered       B. strong         C. safe        D. weak

Miguel’s co-workers don’t quite understand him. One day he is smiling and friendly, a real team player. The next day, he is cross, getting angry over minor things, especially when asked to improve one of his designs.
Identifying your personality characteristics is the first step in developing a good attitude. Are you a positive, confident person or are you shy and reserved? Do you face problems, looking for solutions, or do you feel someone to blame? Characteristics define you. They help you succeed, or they hold you back.
Self-awareness, or understanding the factors that make up your personality, is an important step towards happiness, and happiness is the key characteristic of a good attitude. To become self-aware is to be aware of both your good and bad characteristics.
What are the characteristics that people compliment(恭維) on you? Are you dependable”, “responsible” or “solid”? Pay attention to the compliment because they are a confirmation of your strongest characteristics. You can use these characteristics to create an even better image.
People form opinions about you. Whether they are right or wrong doesn’t enter the question. You, however, can change their opinions by demonstrating the personality characteristics and attitudes that match the way you want to be viewed. In becoming self-aware, understanding how others see you is an important step. This can be painful; but if you are brave enough to try it, it can be an excellent growth experience.
