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

I have been working since I was thirteen, and always in 34 in which I was working with adults. I have had to learn to think and 35 like an adult to be taken seriously. So, I count myself as one who has grown up too fast. I just graduated from high school, and have recently spent some time reflecting(反思)on the 36 eighteen years - thinking about myself, what I have gained, and what 37 I have yet to achieve.
We are expected to work hard, get excellent 38 , be in a good relationship, and know what we want to do 39 . The list goes on and on. But the 40 is clear: We live in a society today that is 41 our childhood. We no longer have many years to be careless and fancy-free. We are expected to 42 the strict school rules and to excel(擅长)in everything we do.
I’ve known these things for a long time, and knew that they 43 me. But, I never really admitted it until last night, when I learned a 44 lesson, taught to me by my boss where I work. We had finished a job at a remote site. It was about 11:30 at night, and we had 45 to his house. We were talking about the 46 he had been making to his home. One of the things he said was “I 47 my basketball hoop(篮圈). ”Then he threw a basketball to me.
I hadn’t 48 a basketball in five years.
We proceeded to shoot hoops for about 5 minutes. Both of us were terribly bad at it, but we spent the whole time 49 like children. Then I realized something: I am still a child. Oh, the law says I’m an adult. But, we are still really and truly children. We all need to have 50_ once in a while.

Dinner parties are out of date. Alumni (毕业生,校友) album are old-fashioned. School leaving is taking on a new turn:it is going online! Graduating students at Qinghua University are saving all their joys and sorrows from university on a CD. Some are setting up their alumni records online, such as Chinaren.com and 5406.net. With computer usage and Internet access becoming even more popular, students are throwing away the traditional graduation book. Instead they are using alumni books online, in CDs or disks, electrolyzing(电解) their graduation in the e-age.
"It is much easier and safer to save." Xu Ziguo, a civil-engineer-major at Qinghua University said. Like his class, most of Qinghua"s to-be graduates are using the CD alumni records and online association. Xu said CD records can save more than the actual books. Photos and videos on school activities and normal campus life, and messages may be all included in the thin plastic with the help of a CD-Writer. "Everything is so lively when I watch it, just like what is happening on campus," Xu said. Another student at the Renmin University of China, Lu Yangzhen said her class saved all the memorable messages on a disk. They use a common chat room online to communicate after graduation. Many classes will keep their homepages on campus for future communication, Lu said.
Dotcom companies are also seizing the opportunity to get more clicks. Chinaren.com said it provided improved services for the users. One service is to send group emails, meaning if a user sends an email to one address, all his or her classmates can get it at the same time. But what if the Dotcom company breaks down one day? Xu said they had left a "backup". That is to use the old way with a person working as the liaison.
55. Which of the following is the best title for the passage?

A. Because they found the traditional form was inconvenient.
B. Because many students can afford to buy a computer.
C. Because computers become more and more popular.
D. Because it is much easier and safer to save, and everything is lively.
57. What kind of service is provided by Dotcom companies?
A. If a user sends an email to one of his or her classmates, the others can get it at the same time.
B. If a user sends an email to a certain address, all his or her classmates can get it at the same time.
C. It isn"t mentioned in the passage.

It was the first snow of winter- an exciting day for every child but not for most teacher. UP until now, I had been able to dress myself for recess (课间休息), but today I would need some help. Miss Finlayson, my kindergarten teacher at Princess Elizabeth School near Hamilton, Ontario, had been through first snow days many times in her long career, but I think she may still remember this one.
I managed go get into my wool snow pants. But I struggled with my jacket because it didn’t fit well. It was a hand-me-down from my brother, and it made me wonder why I had to wear his ugly clothes. At least my hat and matching scarf were mine, and they were quite pretty. Finally it was time to have Miss Finlayson help me with my boots. In her calm, motherly voice she said, “By the end of winter, you will be able to put on your own boots.” I didn’t realize at the time that this was more a statement of hope than of confidence.
I handed her my boots and stuck out my foot. Like most children, I expected the adult to do all the work. After much wiggling and pushing, she managed to get first one into place and then, with a sigh, worked the second one on too.
I announced, “They’re on the wrong feet.” With the grace that only experience can bring, she struggled to get the boots off and went through the joyless task of putting them on again. Then I said, “These aren’t my boots, you know.” As she pulled the offending boots from my feet, she still managed to look both helpful and interested. Once they were off, I said, “They are my brother’s boots. My mother makes me wear them, and I hate them!” Somehow, from long years of practice, she managed to act as though I wasn’t an annoying little girl. She pushed and shoved, less gently this time, and the boots were returned to their proper place on my feet. With a great sigh if relief, seeing the end of her struggle with me, she asked, “Now, where are your gloves?”
I looked into her eyes and said, “I didn’t want to lose them, so I put them into the toes of my boots.”
39. According to the passage, the little girl got ______ from her brother.
A. the wool snow pants and the jacket B. the jacket and the boots
C. the jacket and the hat D. the boots and the gloves
40. What made it so hard for the teacher to help the little girl put her boots on?
A. The gloves in the toes of the boots. B. The slowness of the teacher.
C. The wrong size of the boots D. The unwillingness of the girl
41. It can be inferred that before the little girl finally went out to enjoy the first snow of winter, the teacher had to help her put on her boots______ .
A. once B. twice C. three times D. four times
42. Which of the following sentences from the text BEST indicates that the teacher is very considerate?
A. In her calm, motherly voice she, “By the end of winter,…”(Paragraph 2)
B. With the grace that only experience can bring, she struggled to…(Paragraph 4)
C. …she still managed to look both helpful and interested. (Paragraph 4)
D. …she managed to act as though I wasn’t an annoying little girl. (Paragraph 4)

第三部分:阅读理解(共20小题;每小题2分,满分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.
