【题目】

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. Be-sides, 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

【3】 The main idea of this passage is __________.

A. an introduction to the history of artificial leaves

【题目】 However, a new type of humor, which seems largely from America, has recently __________ (流行）.

【题目】There was once a professor of medicine, who was very strict with his students. Whenever he took the chair on the exam committee, the students would be in fear, because he was seldom pleased with the answers they gave. A student would be lucky enough if he or she could receive a good mark from him. At the end of the term, the students of medicine would take their exam again. Now a student entered the exam room and got seated before the committee. This student was a little nervous as he knew it would not be so easy to get through the exam at all.

The professor began to ask. The student was required to describe a certain illness, his description of which turned out to be OK. Then the professor asked about the cure for the illness, and the student, too, answered just as right. “Good,” said the professor, “and how much will you give the patient?” “A full spoon,” answered the student. “Now you go out and wait for what you can get,” said the professor. At the same time the committee discussed carefully the answers the student had given. Suddenly the student noticed there was something wrong with his last answer. “A full spoon is too much,” he thought to himself. Anxiously he entered the room and cried, “Mr. Professor, I’ve made a mistake! A full spoon is too much for the patient. He can take only five drops. ”

“I’m sorry, sir,” said the professor coldly, “but it’s too late. Your patient has died.”

A. believed that he had passed the exam

B. thought five drops of medicine would cure the patient

A. The patient will be in danger if he’s taken as much as a full spoon.

B. The doctor will be in trouble if he has given the patient a full spoon.

C. Since one spoon is more than five drops, the patient will be all right soon after taking one spoon.

D. If the patient wants to remain safe, he should take no more than five drops at a time.
