Have you ever had the strange feeling that you were being watched? You turned around and, sure enough, someone was looking right at you!
Parapsychologists（靈學(xué)家）say that humans have a natural ability to sense when someone is looking at them. To research whether such a “sixth sense” really exists, Robert Baker, a psychologist（心理學(xué)家）at the University of Kentucky, performed two experiments.
In the first one, Baker sat behind unknowing people in public places and stared at the backs of their heads for 5 to 15 minutes. The subjects（受試者）were eating, drinking, reading studying, watching TV, or working at a computer. Baker made sure that the people could not tell that he was sitting behind them during those periods. Later, when he questioned the subjects, almost all of them said they had no sense that someone was staring at them.
For the second experiment, Baker told the subjects that they would be stared at from time to time from behind a two way mirror in a laboratory setting. The people had to write down when they felt they were being stared at and when they weren’t. Baker found that the subjects were no better at telling when they were stared at and when they weren’t. Baker found that the subjects were no better at telling when they were started at than if they had just guessed.
Baker concludes that people do not have the ability to sense when they’re being stared at. If people doubt the outcome of his two experiments, said Baker, “I suggest they repeat the experiments and see for themselves.”
68. The purpose of the two experiments is to        .
A. explain when people can have a sixth sense
B. show how people act while being watched in the lab
C. study whether humans can sense when they are stared at
D. prove why humans have a sixth sense
69. In the first experiment, the subjects       .
A. were not told that they would be stared at
B. lost their sense when they were stared at
C. were not sure when they would be stared at
D. were uncomfortable when they were stared at
70. The underlined word “outcome” in the last paragraph most probably means      .
A. value  B. result  C. performance      D. connection
71. What can be learned from the passage?
A. People are born with a sixth sense.
B. The experiments support parapsychologists’ idea.
C. The subjects do not have a sixth sense in the experiments.
D. People have a sixth sense in public places.

Be careful of those who use the truth to deceive (cheat). When someone tells you something that is true, but  36  important information that should be included, he can create a false  37  .
For Example, a man once told me, “I just won a hundred dollars on the  38  . It was great. I   39  that ticket back to the store and turned it in   40  one hundred dollars!”
This guy is a winner, right? May be, may be not. Then  41  I discovered that he bought two hundred tickets, and only one was a  42  . He was  43  a big loser!
He didn’t say anything that was false,  44  he left out important information  45  . That’s called a half—truth. Half—truths are not technically  46  , but they are just as dishonest.
Untrustworthy candidates in political campaigns often use this  47  . Let’s say that during Governor Smith’s last term, her  48  lost one million jobs and gained three million jobs. Then she sought another  49  . One of her opponents put an ad saying, “During Governor Smith’s term, the state lost one million jobs!” That’s  50  . However, an honest statement would have been quite different.
Advertisers will sometimes use half—truths. It’s  51  the law to make false claims, so they  52  to mislead you with the truth. An ad  53  blow its own horn, “Nine out of ten doctors lend Yucky Pills to cure nose pimples.” It fails to mention that they only ask ten  54  , and nine of them work for the Yucky Corporation.
This kind of  55  deception happens too often. It’s a fact of life: lies are lies, but sometimes the truth can lie as well.
36. A. makes out           B. leaves out                 C. tries out            D. puts out

In the course of working my way through school, I took many jobs I would rather forget. But none of these jobs was as dreadful as my job in an apple plant. The work was hard; the pay was poor; and, most of all, the working conditions were terrible.
First of all, the job made huge demands on my strength. For then hours a night, I took boxes that rolled down a metal track and piled them onto a truck. Each box contained twelve heavy bottles of apple juice. I once figured out that I was lifting an average of twelve tons of apple juice every night.
I would not have minded the difficulty of the work so much if the pay had not been so poor. I was paid the lowest wage of that time—two dollars an hour. Because of the low pay, I felt eager to get as much as possible. I usually worked twelve hours a night but did not take home much more than $ 100 a week.
But even more than the low pay, what made me unhappy was the working conditions. During work I was limited to two ten-minute breaks and an unpaid half hour for lunch. Most of my time was spent outside loading trucks with those heavy boxes in near-zero-degree temperatures. The steel floors of the trucks were like ice, which made my feet feel like stone. And after the production line shut down at night and most people left, I had to spend two hours alone cleaning the floor.
I stayed on the job for five months, all the while hating the difficulty of the work, the poor money, and the conditions under which I worked. By the time I left, I was determined never to go back there again.
49. Why did the writer have to take many jobs at that time?
A. To pay for his schooling.
B. To save for his future.
C. To support his family
D. To gain some experience
50. The following facts describe the terrible working conditions of the plant EXCEPT ______.
A. loading boxes in the freezing cold                     B. having limited time for breaks
C. working and studying at the same time        D. getting no pay for lunch time
51. What is the subject discussed in the text?
A. The writer’s unhappy school life.               B. The writer’s eagerness to earn money.
C. The writer’s experience to earn money.      D. The writer’s hard work in an apple plant.
52. How is the text organized?
A. Topic—Argument—Explanation
B. Opinion—Discussion—Description
C. Main idea—Comparison—Supporting examples
D. Introduction—Supporting examples—Conclusion

I was in a rush as always, but this time it was for an important date I just couldn’t be late for! I found myself at a checkout counter behind an elderly woman seemingly in no hurry as she paid for her groceries. A PhD student with not a lot of money, I had hurried into the store to pick up some flowers. I was in a huge rush, thinking of my upcoming evening. I did not want to be late for this date.
We were in Boston, a place not always known for small conversation between strangers. The woman stopped unloading her basket and looked up at me. She smiled. It was a nice smile –warm and reassuring—and I returned her gift by smiling back.
“Must be a special lady, whoever it is that will be getting those beautiful flowers,” she said.
“Yes, she’s special,” I said, and then to my embarrassment, the words kept coming out.
“It’s only our second date, but somehow I am just having the feeling she’s ‘the one’. Jokingly, I added, “The only problem is that I can’t figure out why she’d want to date a guy like me.”
“Well, I think she’s very lucky to have a boyfriend who brings her such lovely flowers and who is obviously in love with her,” the woman said.” “My husband used to bring me flowers every week –even when times were tough and we didn’t have much money. Those were incredible days; he was very romantic and – of course – I miss him since he’s passed away.”
I paid for my flowers as she was gathering up her groceries. There was no doubt in my mind as I walked up to her. I touched her on the shoulder and said, “You were right, you know. These flowers are indeed for a very special lady.” I handed her the flowers and thanked her for such a nice conversation.
It took her a moment to realize that I was giving her the flowers I had just purchased. “You have a wonderful evening,” I said. I left her with a big smile and my heart warmed as I saw her smelling the beautiful flowers.
I remember being slightly late for my date that night and telling my girlfriend the above story. A couple of years later, when I finally worked up the courage to ask her to marry me, she told me that this story had helped to seal it for her –that was the night that I won her heart.
小題1:Why was the writer in a hurry that day?
A．He was to meet his girlfriend.B．He had to go back to school soon.
C．He was delayed by an elderly lady.D．He had to pick up some groceries.
小題2:What does the underlined phrase “her gift”(Paragraph 2) refer to?

小題3:Why did the writer give his flowers to the elderly lady?

C．She gave him encouragement.D．She liked flowers very much.

Here’s an idyllic(田園風(fēng)光的) scene: a small village where the sun always shines, crops always grow and your friends drop by to sweep your yard to the sound of guitar music. Animals do what they are told, there is no disease, and lending folks a helping hand makes you richer and wiser. Welcome to FarmVille — current population 69m and rising fast.
“It reminds me of my childhood,” says one player, Lia Curran, 37, a chemist from London. “Right now I’m growing wheat and poinsettia, I’ve got a small orchard, and I’m keeping some chickens and some cows. I like having the animals. It’s comfortable.”
Curran’s young animals, however, are nothing more than a collection of computer-controlled cartoons. FarmVille is an online computer game built into the social networking site Facebook and is described by its players as “addictive”. Launched last June by Zynga Game Network, FarmVille now has more players than Twiter’s entire user base — or more than the population of the UK. The players are largely women over the age of 35.
Jenny Glyn, 33, a London housewife, started playing in September. “I had a look at a friend’s farm and was hooked,” she says. “My first motivation was to overtake her, but I did that pretty quickly. Now there’s something satisfying about growing crops.”
FarmVille intellectually unites the worlds of social networking and gaming. Players are given a patch of ground with six fields, “cash”, a few seeds and a plough and have to build up wealth, skills and neighbors to create bigger, better, richer farms.
Inviting your online friends to play means you earn more and get free gifts; you rise rapidly through the first levels but, once hooked, have to work harder and harder with no final level or goal in sight.
“It’s very moreish,” says Curran. She hasn’t yet paid real-world money to advance in the game, but her friends do. One buys extra virtual currency at the exchange rate of $240 (£145) in FarmVille for $40 (£24) in the real world.
“I’d expanded on FarmVille as much as I could, but I just wanted a pond and some bushes and trees around it,” says the woman, who is too embarrassed to be named. “I didn’t tell my husband I’d paid real money because he’d think I’m mad. But then he did keep me waiting in the car outside our house while he harvested his raspberries.”
Brian Dudley, chief executive at Broadway Lodge, an addiction treatment centre, warns that this sort of obsessive(令人著魔的) play can lead to an addiction as severe as gambling.
59. What does Curran do in the passage?
A. She is a player.                                                      B. She is a farmer who grows wheat and poinsettia.
C. She is a chemist.                                                  D. She is a housewife who raises chickens and cows.
60. By FarmVille, the writer means ______.
A. an addictive farm on which live 69 million farmers
B. a London housewife’s farm
C. an online computer game built into the social networking site
D. a farm on which people grow real crops and play as well
61. In the last but one paragraph, the husband kept the woman waiting outside ______.
A. because he was angry at his wife’s being mad about the farm
B. because he himself was busy with his farm
C. in order to punish his wife for her having paid real money
D. so that his wife would wake up from her addiction to the farm
62. According to the passage, which of the following is NOT true?
A. The population of the UK is less than 69 million.
