If eighteen-year-old Karki doesn't turn out to be the next Edison, I'll chop off my locks This kid invented a solar pane (嵌板) which uses human hair as a conductor and could provide the world with cheap, green electricity, solving the energy crisis.
Karki, a Nepal teenager, who lives in a village in Rural Nepal, used human hair to replace silicon, which is a common but expensive component of solar panels.
By using hair as a replacement, Karki says solar panels can be produced for around 23 pounds. But if they were mass-produced, Karki says they could be sold for less than half that price, which could make them a quarter of the price of those already on the market.
The solar panel works because melanin, the substance giving hair its color, is light sensitive and can act as an electrical conductor. Karki was inspired to follow this route by a Stephen Hawking book, which explained how to create energy from hair.
The device (設(shè)備) Karki has shown is able to produce 9V or 18W of energy -- plenty to charge a mobile phone. Half a kilo of hair can be bought for only 16p in Nepal and lasts a few months, where as a pack of batteries would cost 50p and last a few nights," according to Karki.
Karki has now sent out several devices to other districts near his village for testing. "First I wanted to provide electricity for my home, then my village. Now I am thinking for the world," he said.
Karki says the idea is more important than ever because of the urgent need for renewable energies in the face of limited power sources and global warming. Slowly, natural resources are decreasing. One day we will be in a great crisis. This is an easy solution for the crisis we are having today.
64. What is the best title of the passage?
A. Introduction of Solar Panels            B. Functions of a New Solar Panel
C. Special Solar panel Materials                      D. Karki Invented a New Solar Panel
65. Why did Karki want to invent a solar panel with hair?
A. Because hair is not very expensive.
B. Because silicon is hard to find.
C. Because he wanted to provide electricity for his home.
D. Because the energy crisis is very serious in his home town.

B. Karki can predict what will happen in the future
C. the energy crisis will disappear in the future

For almost two months Dominic York, a 23-year-old hairdresser, wandered about hospitals all night, wearing a white coat and pretending he was a doctor. Yesterday he proudly claimed in court that despite his complete lack of medical experience or qualifications, he had saved several people’s lives. He had even been allowed to assist a surgeon during an emergency operation on a patient who was about to die on something she had swallowed.
“I watched one of those TV dramas about a hospital and suddenly I felt like playing one of the roles myself. So I put on a white jacket and a stethoscope(聽診器)and walked around one of the biggest hospital in London. At first I just watched. Once you learn how doctors talk to patients, nurses and others doctors, it’s easy to take people in,” he said.
One of the patients he treated was Laura Kennan. She had been knocked down by a car and fainted. When she came to in hospital, York was standing over her.
“He looked very professional. He told me his name was Doctor Simon. Then he gave me some sort of injection,” she said. And then he suddenly cleared off when a nurse asked who he was. She didn’t think there was anything wrong. “I would never have realized he was a fake if a policewoman hadn’t showed me his photograph a week later. When the policewoman told me who he really was, I could hardly believe my ears.”
Judge Raymond Adams told York that he was “ shocked and horrified” that he got away with his deceiving for so long. And they sentenced him to eighteen months in a special prison for criminal with mental disorders.
“I can only hope that this will not lead to further problems. After all, you will have considerable opportunity to study the behaviour of the psychiatrists(精神科醫(yī)生)who will look after you while you are there. If you try to persuade people that you yourself are a psychiatrist after you are set free, I shall make sure that you are given a much longer sentence.” Judge Adams warned York.
【小題1】York was proud of the fact that ___________.

A.a(chǎn) surgeon let him watch an operation.
B.he could perform some duties of a doctor
C.he had cheated doctors for so long
D.people thought he could become a real doctor
【小題2】York learned how to behave like a doctor by __________.
A.watching other doctors work
B.talking to doctors and nurses
C.getting some training and experience
D.observing doctors while he was a patient
【小題3】Why was Laura Kennan in hospital?
A.She had swallowed something and almost died.
B.She had to have and emergency operation.
C.She had been injured in a road accident.
D.She had lost consciousness while driving.
【小題4】The judge’s remark implied that York would be more severely punished if he _________.
A.pretended to be a psychiatrist
B.tried to get away from prison
C.was proud of what he had done
D.studied the behaviour of the psychiatrist
