Some years ago, an American policeman found a woman lying near a lonely road. She did not appear to have   21  ,but she was trembling and clearly in a state of shock, so he rushed her to the nearest hospital. She began to tell the doctor on duty a story which was  22  in all respects. She had been  23  along a country road when she had been stopped by a flying saucer  24  in front of her. She had been forced to leave the car and enter the flying saucer by creatures which looked like human beings and which could easily make themselves  25  although they could not speak. They could read her thoughts and she could read  theirs .They tested her politely and allowed her to leave after carrying out a number of tests on her. As she otherwise seemed to be  26  ,the doctor decided that she was probably suffering from the side effects of some medicine. The woman insisted on being allowed to go home ,but when she gave her address, it was in a town over a thousand miles from the  27  .The police then started to make inquires and soon  28  that there was already a  29  going on for the woman, whose husband badly reported that she had  30  .Her car had been found with the driver’s door open and the engine running. In front of the car the surface of the road had been completely destroyed—not by an explosion or anything of that kind, but as if a large, round, white-hot object had burnt through it.

What will power your house in the future？Nuclear，wind，or solar power？According to scientists at the Massachusetts Institute of Technology (MIT) in the US，it might be leaves — but artificial (人造的) ones.

Natural leaves are able to change sunlight and water into energy. It is known as photosynthesis (光合作用)．Now researchers have found a way to imitate this seemingly simple process.

The artificial leaf developed by Daniel Nocera and his colleagues at MIT can be seen as a special silicon chip with catalysts (催化剂)．Similar to natural leaves，it can split water into hydrogen and oxygen when put into a bucket of water. The hydrogen and oxygen gases are then stored in a fuel cell，which uses those two materials to produce electricity，located either on top of a house or beside the house.

Though the leaf is only about the shape of a poker card，scientists claimed that it is promising to be an inexpensive source of electricity in developing countries. “One can imagine villages in India and Africa not long from now purchasing an affordable basic power system based on this technology,” said Nocera at a conference of the American Chemical Society.

The artificial leaf is not a new idea. The first artificial leaf was invented in 1997 but was too expensive and unstable for practical use. The new leaf，by contrast，is made of cheap materials，easy to use and highly stable. In laboratory studies，Nocera showed that an artificial leaf prototype (原型) could operate continuously for at least 45 hours without a drop in activity.

The wonderful improvements come from Nocera's recent discovery of several powerful，new and inexpensive catalysts. These catalysts make the energy transformation inside the leaf more efficient with water and sunlight. Right now，the new leaf is about 10 times more efficient at carrying out photosynthesis than a natural one. Besides，the device can run in whatever water is available；that is，it doesn't need pure water. This is important for some countries that don't have access to pure water.

With the goal to “make each home its own power station” and “give energy to the poor”，scientists believe that the new technology could be widely used in developing countries，especially in India and rural China.

1.Which of the following orders correctly shows how the artificial leaf is used to produce electricity?

a．artificial leaves split water into hydrogen and oxygen

b．the hydrogen and oxygen gases are stored in a fuel cell

c．the artificial leaves are put in water

d．the fuel cell uses hydrogen and oxygen to produce electricity

A. c，a，b，d                               B．c，b，a，d  

C．b，c，a，d                 D．c，a，d，b

2.The purpose of the scientists at MIT in developing the new artificial leaf is to________.

A．build up more power stations in the world

B．provide cheaper energy for developing countries

C．offer people in developing countries access to pure water

D．gain a deeper understanding of the photosynthesis process

3.The main idea of this passage is ________.

A．an introduction to the history of artificial leaves

B．a mixture of water power and solar energy

C．giving energy to the poor

D．an invention copying photosynthesis
