With only about 1, 000 pandas left in the world, China is desperately trying to clone the animal and save the endangered species(物种). That’s a move similar to what a Texas A & M University researchers have been undertaking for the past five years in a project called “Noah’s Ark”.
Noah’s Ark is aimed at collecting eggs, embryos(胚胎), semen and DNA of endangered animals and storing them in liquid nitrogen. If certain species should become extinct, Dr. Duane Kraemer, a professor in Texas A & M’s College of Veterinary Medicine, says there would be enough of the basic building blocks to reintroduce the species in the future.
It is estimated that as many as 2, 000 species of mammals, birds reptiles will become extinct in over 100 years. The panda, native only to China, is in danger of becoming extinct in the next 25 years.
This week, Chinese scientists said they grew an embryo by introducing cells from a dead female panda into the egg cells of a Japanese white rabbit. They are now trying to implant the embryo into a host animal.
The entire procedure could take from three to five years to complete.
“The nuclear transfer(核子移植) of one species to another is not easy, and the lack of available(capable of being used) panda eggs could be a major problem,” Kraemer believes. “They will probably have to do several hundred transfers to result in one pregnancy (having a baby). It takes a long time and it’s difficult, but this could be groundbreaking science if it works. They are certainly not putting any live pandas at risk, so it is worth the effort,” adds Kraemer, who is one of the leaders of the Project at Texas A& M, the first-ever attempt at cloning a dog.
“They are trying to do something that’s never been done, and this is very similar to our work in Noah’s Ark. We’re both trying to save animals that face extinction. I certainly appreciate their effort and there’s a lot we can learn from what they are attempting to do. It’s a research that is very much needed.”

The aim of “Noah’s Ark” project is to _______.

A.make efforts to clone the endangered pandas
B.save endangered animals from dying out
C.collect DNA of endangered animals to study
D.transfer the nuclear of one animal to another


According to Professor Kraemer, the major problem in cloning pandas would be the lack of _______.

A.available panda eggs B.host animals C.qualified researchers D.enough money


The best title for the passage may be _______.

A.China’s Success in Pandas Cloning
B.The First Cloned Panda in the World
C.Exploring the Possibility to Clone Pandas
D.China —the Native Place of Pandas Forever


From the passage we know that _______.

A.Kraemer and his team have succeeded in cloning a dog
B.scientists try to implant a panda’s egg into a rabbit
C.Kraemer will work with Chinese scientists in clone researches
D.about two thousand of species will probably die out in a century

A Groundbreaking Event
It was an unforgettable field trip. Twenty-six fifth-graders from George Bancroft Elementary School, in Washington, D.C., went to the White House on Friday. They used shovels, rakes and wheelbarrows to help First Lady Michelle Obama break ground on a new vegetable garden.
This White House garden is the first since World War Ⅱ. In the 1940s, First lady Eleanor Roosevelt planted a White House “Victory Garden” to encourage Americans to grow gardens at home. Mrs. Obama’s new garden is an L-shaped patch near the fountain on the South Lawn. Vegetables to be planted include lettuce, peas, collard greens, onions and spinach. A herb garden will grow garlic, sage and cilantro. These herbs are used in Mexican food, an Obama family favourite. White House chefs will prepare meals for the First Family with food from the garden and some of the produce will be donated to Miriam’s Kitchen, a soup kitchen near the White House.
Health food is important to Mrs. Obama. She said that the purpose of the garden is to make sure that her family, the White House staff, and guests eat fresh vegetables. Mrs. Obama has also said that she hopes the new White House garden will help educate Americans about the importance of fresh, nutritious food at a time when obesity is a national crisis. A diet high in natural, unprocessed foods helps people maintain a healthy weight.
Mrs. Obama said she has found that her daughters, Malia, 16, and Sasha, 13, like vegetables more if they have been involved in growing them. “If they have been involved in planting and picking the vegetables, they are much more curious about giving them a try,” she said. When Bancroft students go back to the White House this summer they will get to taste the vegetables they helped to grow. After they help to harvest the crops, they will cook them in the White House kitchen and then eat them.
What did the Bancroft students do outside the White House?

A.They gave shovels, rakes and wheelbarrows to the First Lady.
B.They did research on what life is like for the First Lady.
C.They helped First Lady Michelle Obama to plant a garden.
D.They gave fruit and vegetables to the First Lady.

The reason why First Lady Eleanor Roosevelt planted a “Victory Garden” was that _________.

A.she did it just for fun.
B.she wanted other citizens to follow her example.
C.she wanted to please her husband.
D.she wanted to get some gardening experience.

Why did Mrs. Obama plan to plant the garden?

A.Because she wanted her children to become gardeners.
B.Because she wanted to know what gardening is like.
C.Because she wanted to become a second Eleanor Roosevelt.
D.Because she wanted people in the white house to eat a healthy food.

Liverpool city council want to clear the city of fat pigeons. They say that people are feeding the birds, which makes them fat. The pigeons get bigger because their normal diet would consist of seeds and insects, not high-fat junk food they are eating in the city centre.
The council want people to know that everyone who feeds the pigeons is responsible for the streets being so crowded with these birds. They hope to encourage the birds to move away from the city centre and into parks and open spaces.
Ten robotic birds have been brought into the city centre to scare the pigeons away and visitors are asked not to give the pigeons any food. The mechanical birds - known as “robops” - will sit on the roofs of buildings. They can be moved around to different locations. They look like a peregrine falcon, which is a bird that kills pigeons. They even make noises and flap their wings to scare the pigeons. They hope that the pigeons will go away before the city becomes the European Capital of Culture in two years.

Today is Sarah’s birthday. She is seventy-five. We asked a few old friends to dinner.
Like most elderly people, I suppose, we spent most of the evening talking about old times. Thirty years ago, the village used to be a quiet place. Now it has changed. Every Sunday hundreds of cars pass through the village at what I think a dangerous speed. They make the village almost as noisy as the streets of a large town. As a boy I enjoyed riding on the backs of the farm horses. Things are different now. Today there are very few horses working on the farms. The farm workers today drive tractors, not horses. A man is not of much use on a farm unless he knows all about machines. Now almost every house in the village has a TV set. Is it a good thing for children to spend the evening sitting in front of a TV set? When I was young I did not waste my time indoors. I would spend the long summer evenings outdoors. I would play with my friends, go fishing or walk by the river. When my grandchildren asked me the reason why I haven’t bought a TV set, I tell them there are many books I still want to read. I can’t find time for both reading and watching TV.
The old like to talk about _______.

A.themselves B.others C.the past D.nothing

When I was a boy, I _______ riding on farm horses.

A.used to see people
B.disliked
C.was fond of
D.saw some elderly people

Computer programmer David Jones earns £35,000 a year designing new computer games, yet he cannot find a bank ready to let him have a credit card (信用卡). Instead, he has been told to wait another two years, until he is 18. The 16-year-old works for a small firm in Liverpool, where the problem of most young people of his age is finding a job. David’s firm releases (推出) two new games for the fast throwing computer market each month.

But David’s biggest headache is what to do with his money. Even though he earns a lot, he cannot drive a car, take out a mortgage (抵押贷款), or get credit cards. David got his job with the Liverpool-based company four months ago, a year after leaving school with six O-levels and working for a time in a computer shop. “I got the job because the people who run the firm knew I had already written some programs,” he said. David spends some of his money on records and clothes, and gives his mother 50 pounds a week. But most of his spare time is spent working.
“Unfortunately, computing was not part of our studies at school,” he said. “But I had been studying it in books and magazines for four years in my spare time. I knew what I wanted to do and never considered staying on at school. Most people in this business are fairly young, anyway.” David added:“I would like to earn a million and I suppose early retirement is a possibility. You never know when the market might die away.”
In what way is David different from people of his age?

A.He often goes out with friends.
B.He lives with his mother.

B.He had written some computer programs.
C.He was good at playing computer games.
D.He had learnt to use computers at school.

Why did David decide to leave school and start working?
