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 (催化劑). 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

Like any good mother, when Karen found out that another baby was on the way, she did what she could to help her three-year-old son, Michael, prepare for a new sibling. They find out that the new baby is going to be a girl, and day after day, night after night, Michael sings to his sister in Mommy's tummy.

The pregnancy progresses normally for Karen. But complications arise during delivery. Finally, Michael's little sister is born. But she is in serious condition. With siren howling in the night, the ambulance rushes the infant to the intensive care unit at St. Mary's Hospital.

The little girl gets worse. The doctor tells the parents, "There is very little hope. Be prepared for the worst." Karen and her husband have fixed up a special room in their home for the new baby — now they plan a funeral.

Michael, keeps begging his parents to let him see his sister, "I want to sing to her," he says. But kids are never allowed in Intensive Care. However, Karen makes up her mind. She will take Michael whether they like it or not.  “If he doesn't see his sister now, he may never see her alive.” She dresses him in an oversized scrub suit and marches him into ICU. The head nurse recognizes him as a child and bellows, "Get that kid out of here now! " The mother, the usually mild-mannered lady glares steel-eyed into the head nurse's face, her lips a firm line. "He is not leaving until he sings to his sister!" Karen tows Michael to his sister's bedside. He gazes at the tiny infant losing the battle to live. And he begins to sing.

"You are my sunshine, my only sunshine, you make me happy when skies are gray”

Instantly the baby girl responds. The pulse rate becomes calm and steady.

"You never know, dear, how much I love you. Please don't take my sunshine away "

The ragged, strained breathing becomes as smooth as a kitten's purr.

Keep on singing, Michael. Tears conquer the face of the bossy head nurse as well as Karen.

Funeral plans are scrapped. The next, day — the very next day — the little girl is well enough to go home!

NEVER GIVE UP THE ONE WE LOVE!

1.How did Michal’s feel when he knew that he was going to have a sister?

A. indifferent. B. worried.

C. expectant. D. disappointed.

2.The doctor recommended the family ___________.

A. get ready for the worst result.

B. wait for the hope in the near future.

C. prepare much more money for the infant.

D. prepare for another chance in other hospitals.

A. pointed. B. yelled.

C. whispered. D. ignored.

4.What happened when Michael sang to his little sister?

A. The little baby responded to his song and woke up immediately.

Of all my teachers, Mr Moore is the one who impress me most. He is 34, so he looks young for his age. And he's one of the most popular teacher in our school. Mr Moore pays more attention to his way of teaching, comparing with other teachers.

He tries different ways to make his classes actively and lively. On his opinion, we should not only know "what", but understand "why". So, instead giving us answers immediately, he encourages us to think by myself whenever he puts forward questions. With his help, we've learned from how to settle problems. He leads us to such a wonderful world of "why" as we all admire and respect him.
