　　A man sits on a chair, with rubber pads(垫)tied to his head．Someone is going to fire an electric current through his brain．

　　Sounds like a horror movie?Actually, the man is Telegraph journalist．Nick Collins．He is getting ready to test the newly－invented“electric thinking cap”．

　　Professor Johansen Berg, a neurologist at Oxford University, has discovered that firing a tiny electrical current to part of the brain can help people learn faster．

　　“It'S completely safe．The electric current is one thousand times lower than anvthing that could cause damage,”Kadosh,a researcher at Oxford University, told the Daily凇反Z eadier this year．

　　In a test, 15 volunteers were taught to press a set of buttons in three different, orders．Just like playing the piano．Electricity was fired into the area of their brains that eontrols movement．It ran from the front part of the head to a point above the ear．The electricitv was kept on for 10 minutes while the volunteers completed a task．

　　When the electric current ran in one diieetion, researchers found that volunteers leamed things 10 times more quickly．But if the current was sent the other way, their brain cells slowed down．

　　The cⅡrf每ijIf畜药}：ects the movement area of the brain．This means the method can onlv improve people'S learning skills that have some．thing to d．o with that muscle, such as rowing a boat or playing the piano．But scientists say it could be used in other areas of learning, or even(中风)．help people who have suffered a stroke(中风)．

　　The effects can last for about half an hour after the current is stopped．However, the researchers say that daily treatment could have a good, long-lasting effect．Electric caps could be produced SO that people could receive the treatment in clinics or even at home．

　　“I'm sure there are lots of people who would like to raise their normal abilities,”

　　Kadosh says．‘‘But should people be allowed to do this?It is all up for debate．''

　　The repairman told me, “No charge, Professor Pan! We’re friends．”

　　“I’d rather pay, ” I replied．“If it’s free, I can’t afford it!”

　　Chinese often refuse payment for professional services, insisting, “We’re friends now!” But then they show up later to ask me to tutor them in English, or get them into an American university, and I wish I’d have just paid the 30 yuan I owed them in the first place!

　　According to the Americans, “There is no free lunch．”, means that there’s a price for everything．And I’m always looking around to figure out what this means．

　　Many of our neighbours have given us fruit or flowers or costly teas, never asking anything in return．For years, a bicycle repairman has repeatedly refused to let me pay him．“Wait until you have something major to fix!” he insists．

　　I mentioned to a peasant friend that I wished I had a stone mill to grind(磨)flour for bread．A month later he showed up with a beautiful mill that he’d had his uncle in the countryside carve from a solid block of granite(花岗石)．

　　Chinese generosity(慷慨)is a real education for Americans　like me, who would rather avoid social entanglements(纠纷)and just hand over the money．But cash can’t compensate(补偿)for the greatest gift－friendship．

　　When an American saw some of my friends sitting on bamboo stools under the trees, sipping(呷)tea, he said, “They must have nothing better to do．” “Actually,” I said, “they are professors, with plenty to do．But probably you are right in saying that, at this moment, they have nothing better to do．And neither do I!”?

　　And I joined the group．When chatted about tea and Chinese cooking and how much my boys have grown since we arrived．One man said, “They were pocket-sized when you came here．Now they’re taller than you．How time flies!”

　　How life flies．And Chinese are smart enough to share what they know they cannot keep．They freely give off their time, never too busy to help a friend．And they are teaching me, slowly, to both give and receive．So the next time someone says, “No charge．We’re friends!” I will thank them heartily．But if they show up later asking me to tutor them in English, I’ll make sure they tutor my son in Chinese as well, because there’s still no free lunch．

(1)

Why did the author insist paying the repairman while he was offered free repairs?
[　　]
A．	Because he was an upright man．
B．	Because he didn’t know the repair man．
C．	Because he thought it natural to pay for other’s service．
D．	Because he didn’t want to help others in return．

(2)

Generally, the author thinks that ________．
[　　]
A．	Chinese are generous and always ready to help their friends
B．	Chinese are good at exchange of equal values
C．	Chinese are free enough to drink and chat with their friends
D．	Chinese are helpful but don’t treasure time

(3)

The best title for the passage should be “________”．
[　　]
A．	Still No Free Lunch
B．	A Good Lesson From Chinese
C．	True Help Or Not
D．	Learn To Both Give And Receive

(4)

Which of the following is TRUE?
[　　]
A．	All the Chinese that once gave the author help have asked him to tutor them in English．
B．	When a peasant knew the author needed a mill, he made one for the author himself．
C．	The author thinks that Chinese are wise enough to enjoy the limited life．
D．	The author is not used to the Chinese ways to make friends．
