British and American scientists are raising genetically modified(转基因的) 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(猪仔), 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.

第二部分：阅读理解（第一节20小题，第二节5小题；每小题2分，满分50分）
第一节：阅读下列短文, 从每题所给的四个选项 (A、B、C和D) 中, 选出最佳选项。
I'm from the South Bronx. At 7, my neighborhood was the beginning and end of my universe. It was a small town to me. Everyone knew each other, so if you got into trouble in school, chances are your mom knew about it before you got home. I felt watched over and safe.
But just before I turned 8, things began to change. I watched two buildings on my block burn down. I remember seeing my neighbor Pito go up and down the fire escape to get people out. Where were the firemen? Where was the truck? Somebody must have called them.
That same summer, after serving two tours in Vietnam, my brother was killed in the South Bronx. He was shot above the left eye and died instantly.
People who could moved out of the neighborhood, and all I wanted to do was get out, too. I used education to get away from there and got good at avoiding the topic of where I was from. To be from the South Bronx meant that you were not a good person. It felt like a stain.
After college, I didn't want to come back to the South Bronx, but in order to afford graduate school, I had to. I was almost 30 and could only afford to live at my parents' home. It felt like a defeat, and I hated it.
At the same time, the city was planning a huge waste facility here, and no one seemed to care — including many of us who lived here. They were like, "Well, it's a poor community; what's the difference?"
I was very angry. It drove me to act. It moved my spirit in a way that I didn't know was possible. And it changed my beliefs — it changed the way I felt about myself and my community. I worked hard with others who felt the same way, and together, we defeated the plan.
After that, I realized it's just as important to fight for something as it is to fight against something. So we dreamed up a new park on the site of an illegal waste dump — and after many community clean-ups, along with $3 million from the city, we have one. And it's a glory. It was the seed from which many new plans for our community have grown.
Today, the South Bronx is no longer a stain; it's a badge(象征) of honor for me. I believe that where I'm from helps me to really see the world. Today, when I say I'm from the South Bronx, I stand up straight. This is home, and it always will be.

We show an amazing tolerance for a form of pollution that is a growing problem: noise. Airplane traffic is increasing by five percent a year. Urban noise is doubling every ten years. By air, land and sea, we are facing an onslaught of noise that is threatening our ability to live in this world. We have granted ourselves the right to make noise. But what about our responsibilities? Have we developed a sense of acoustic responsibility?
The evidence suggests that we have not. Many people seem to believe they have an unlimited right to make noise with cars and motorbikes, and with loud music at home and in the street. In some countries measures have been taken to force people to make less noise. In Britain, for example, a law has been passed preventing people from disturbing their neighbors with music at night.
It is widely accepted that we should deal with our rubbish in a responsible way Noise is in reality a particularly insidious form of rubbish. It destroys community life, pursues us into our homes, keeps us from sleeping and is the cause of many stress-related illnesses, as well as hearing loss. Our acoustic environment belongs to all of us. Everyone has the right to use it, but no one has the right to abuse it. Let’s start using it responsibly.
1. The underlined word “acoustic” in the first paragraph probably means ________.
A. environment B. pollution C. sound D. rubbish
2. Which of the following statements is NOT correct?
A. Nowadays everyone thinks it’s all right to make noise.
B. British law protects people from their neighbors’ music at night.
C. The level of noise produced in cities is twice as high now as ten years ago.
D. Noise can sometimes cause hearing loss.
3. The passage is probably written to _______.
A. introduce acoustic responsibility B. call for people to make less noise
C. compare rubbish and noise D. describe people’s attitude to noise

Earthquakes are the shaking, rolling or sudden shock of the earth’s surface. Earthquakes happen along "fault lines" in the earth’s crust. Earthquakes can be felt over large areas although they usually last less than one minute. Earthquakes cannot be predicted -- although scientists are working on it!
Most of the time, you will notice an earthquake by the gentle shaking of the ground. You may notice hanging plants swaying or objects wobbling on shelves. Sometimes you may hear a low rumbling noise or feel a sharp jolt. A survivor of the 1906 earthquake in San Francisco said the sensation was like riding a bicycle down a long flight of stairs.
The intensity of an earthquake can be measured. One measurement is called the Richter scale. Earthquakes below 4.0 on the Richter scale usually do not cause damage, and earthquakes below 2.0 usually can’t be felt. Earthquakes over 5.0 on the scale can cause damage. A magnitude 6.0 earthquake is considered strong and a magnitude 7.0 is a major earthquake. The Northridge Earthquake, which hit Southern California in 1994, was magnitude 6.7.
Earthquakes are sometimes called temblors, quakes, shakers or seismic activity. The most important thing to remember during an earthquake is to DROP, COVER and HOLD ON. So remember to DROP to the floor and get under something for COVER and HOLD ON during the shaking.
1. Which statement about earthquakes is not correct?
A. Earthquakes are the result of the sudden shock of the earth’s surface.
B. Earthquakes usually can be felt because they can last for a long time.
C. There are usually some signs for people to notice an earthquake.
D. People can feel an earthquake over 6.0 because it is very strong.
2. According to the passage, when the earthquake happened, a survivor of the 1906 earthquake in San Francisco_______.
A. was riding a bicycleB. was just climbing the stairs
C. heard a low rumbling noise D. felt like riding a bicycle
3. What can be inferred from the passage?
A. Most of the time, people can not feel or predict the earthquakes.
B. Earthquakes are sometimes called temblors, quakes shakers or seismic activity.
C. The Northridge Earthquake in Southern California in 1994 caused severe damage.
D. When an earthquake happens, it is important to drop on the floor immediately.

A．By keeping their physical fitness．	B．By cutting the calories in their diet．
C．By resetting their clock of aging．	D．By limiting the protein in their diet．
