British and American scientists are raising genetically modified(轉(zhuǎn)基因的) pigs in the hope of providing organs for transplant(移植) to humans, the project leader wrote in a newspaper Sunday.
Scientists in London and California have begun conducting the genetic experiments to find a solution to record–long waiting lists for organ transplants, Robert Winston said in an opinion piece written for Britain's Sunday Times.
In Britain alone, around 8,000 patients are waiting for a transplant.
"People needing a new heart or liver are waiting for someone else to die – usually a violent death in a traffic accident," Winston wrote in the newspaper. He said his team was "trying to modify pigs so their organs might save the lives of humans."
The scientists are introducing human genes into the animals to reduce the chances of the organs being rejected by patients, as has been common in previous attempts to use animal tissues, said Winston, who heads the Institute of Reproductive and Developmental Biology at London's Hammersmith Hospital.
Working with Dr. Carol Redhead of the California Institute of Technology, Winston's team has injected human genes directly into male piglets(豬仔), adding them to the animal's sperm(精子).
He said that pigs involved in experiments had successfully produced transgenic sperm, but acknowledged that British and European laws had prevented the team from using the pigs to mate.
The Sunday Times newspaper reported that the experiments would be moved to the United States following difficulties with funding and regulations in Britain. It said the pigs would be bred in Missouri.
"Our U.S. friends will benefit from our technology and the income we might have produced for Britain will be lost," Winston wrote.
Some scientists have previously blamed the idea of using animal organs for human transplant, saying the technique risks spreading animal viruses to humans. Winston said his research project is attempting to breed virus-free pigs.
1. Scientists are introducing human genes into the animals to ____________.
A. make the organs healthier | B. reduce the pain of animals |

D. it may cause a conflict between humans and animals |
3. According to Winston, it seems ___________ to Britain to move the experiments to the United States.
A. a pity | B. a pride | C. a disaster | D. a good idea |
4. It can be inferred from the passage that ____________.
A. animal organs are commonly used for human transplant now |

If you look for a book as a present for a child,you will be spoiled for choice even in a year there is no new Harry Potter. J.K Rowling’s wizard is not alone.The past decade has been a harvest for good children’s books, which has set off a large quantity of films and an increased sales of classics such as The Lord of the Rings.
Yet despite that, reading is increasingly unpopular among children.According to statistics in 1997, 23% said they didn’t like reading at all.In 2003, 35% didn’t.And around 6% of the children leave primary school each year unable to read properly.
Maybe the decline is caused by the increasing availability of computes games.Maybe the books boom has affected only the top of the educational pile.Either way, Chancellor Cordon Brown plans to change things for the bottom of the class.In his pre-budget report, he announced the national project of Reading Recovery to help the children struggling most.
Reading Recovery is aimed at six year olds, who receive four months of individual daily half-hour classes with a specially trained teacher.An evaluation this year reported that children on the school made 20 months’ progress in just one year, whereas similarly weak readers without special help made just five months’ progress ,and so ended the year even further below the level expected for their age.
International research tends to find that when British children leave primary school, they read well, but read text often for fun than those elsewhere.Reading for fun matters because children who are keen on reading can report lifelong pleasure and loving books is an excellent indicator of future educational success.According to the OECD, being a regular and enthusiastic reader is of great advantage.

He is talent and charm(魅力) have made him the No.1 Chinese classical artist in the world. He played in the grand Beijing Olympic opening ceremony last summer, watched by a TV audience of 5 billion.
Lang Lang, 26, is the first Chinese pianist to play with the world’s top orchestras, making his debut at the Carnegie Hall in New York at 18, while still a student.
Lang Lang’s charm and fondness for sharp clothes make him a natural fit to represent(代表)China’s new international image. According to the British newspaper the Times, “The Lang Lang effect” is responsible for driving 36 million Chinese children to learn the piano.
Now in China children are learning Chopin(肖邦) and Western orchestras are touring Chinese cities, but can China ever export(出口)its own music to the west? Lang is trying. His cooperation with the London Symphony Orchestras this month includes a performance of Dragon Songs, an album of traditional Chinese classics.
Behind the international recognition, however, is a fascinating story of a gifted child. Lang grew up with his father’s own musical ambition and high expectations. It is not hard to imagine how boring it must be to practice the piano every day. Lang said that he once hated his hands and the piano. He injured his right hand six years ago and had to rest. “That was the best month,” he says, without hesitation. “I had a date. I saw a Broadway show and saw Britney Spears in concert.”

A. He played in the Beijing Olympic opening ceremony last summer.
B. He has as many as 5 billions fans in China.
C. He is the first Chinese pianist to play with the world’s top orchestras.
D. He plays the piano so well and has a good international image.

"Hey, don't read in the hallway. Your eyesight will be damaged." You must have heard such warnings many times. “Don’t read in poor light!” This is one of the common beliefs that are supposed to help us live a healthy life. Such beliefs are, however, without scientific basis(根據(jù)), according to a paper published recently in the British Medical Journal.
Do you believe in the following sayings?
Reading in poor light ruins your eyesight.
In poor light, you might blink (眨眼) more, suffer from drying and have trouble focusing. But most of eye experts believe it is unlikely to do any damage forever.
We must drink at least eight glasses of water a day.
In 1945, the Nutrition Council in US suggested that people need to drink 2.5 litres of water a day. But the water contained in food, particularly fruit and vegetables, as well as in milk, juice and soft drinks, also counts towards the total.
We only use 10 percent of our brains.
This idea appears as early as 1907. People have long argued about our power of self-improvement and our brains’ possible abilities. But X-rays show that no area of the brain is silent or inactive.
Shaving your legs causes hair to grow black faster and thicker.
This theory is also illusion. Studies say that shaving has no effect on the thickness or rate of hair growth. Just over time, the edge of hair gets worn away and thus the edge of long hair becomes finer (更細(xì)).
1.What does the paper say about some common beliefs?
A. They are useful knowledge in life.
B. They help us live in healthy ways.
C. They are well-known theories.
D. They do not have scientific basis.
2.Which of the following is TRUE according to the passage ?
A. People use 90 percent of their brains.
B. Shaving your legs will give you thicker hair.
C. Reading in poor light does harm to people’s eyes.
D. People need not less than eight glasses of water a day.

A. a wrong idea B. a powerful evidence
C. an interesting story D. a clear instruction
4.This passage is most likely to be found in __________ .
A. a newspaper B. a guide book
C. a history textbook D. an advertisement

Pacing and Pausing
Sara tried to befriend her old friend Steve's new wife, but Betty never seemed to have anything to say. While Sara felt Betty didn't hold up her end of the conversation, Betty complained to Steve that Sara never gave her a chance to talk. The problem had to do with expectations about pacing and pausing.
Conversation is a turn-taking game. When our habits are similar, there's no problem. But if our habits are different, you may start to talk before I'm finished or fail to take your turn when I'm finished. That's what was happening with Betty and Sara.
It may not be coincidental that Betty, who expected relatively longer pauses between turns, is British, and Sara, who expected relatively shorter pauses, is American. Betty often felt interrupted by Sara. But Betty herself became an interrupter and found herself doing most of the talking when she met a visitor from Finland. And Sara had a hard time cutting in on some speakers from Latin America or Israel.
The general phenomenon, then, is that the small conversation techniques, like pacing and pausing, lead people to draw conclusions not about conversational style but about personality and abilities. These habitual differences are often the basis for dangerous stereotyping (思維定式). And these social phenomena can have very personal consequences. For example, a woman from the southwestern part of the US went to live in an eastern city to take up a job in personnel. When the Personnel Department got together for meetings, she kept searching for the right time to break in --- and never found it. Although back home she was considered outgoing and confident, in Washington she was viewed as shy and retiring. When she was evaluated at the end of the year, she was told to take a training course because of her inability to speak up.
That's why slight differences in conversational style --- tiny little things like microseconds of pause --- can have a great effect on one's life. The result in this case was a judgment of psychological problems --- even in the mind of the woman herself, who really wondered what was wrong with her and registered for assertiveness training.
1.What did Sara think of Betty when talking with her?
A. Betty was talkative. B. Betty was an interrupter.
C. Betty did not take her turn. D. Betty paid no attention to Sara.
2.57. According to the passage, who are likely to expect the shortest pauses between turns?
A. Americans. B. Israelis. C. The British. D. The Finns.
3.58. We can learn from the passage that ______.
A. communication breakdown results from short pauses and fast pacing
B. women are unfavorably stereotyped in eastern cities of the US
C. one's inability to speak up is culturally determined sometimes
D. one should receive training to build up one's confidence
