For centuries, medical pioneers have refined a variety of methods and medicines to treat sickness, injury, and disability, enabling people to live longer and healthier lives.

“A salamander (a small lizard-like animal) can grow back its leg. Why can't a human do the same?” asked Peruvian-born surgeon Dr. Anthony Atala in a recent interview. The question, a reference to work aiming to grow new limbs for wounded soldiers, captures the inventive spirit of regenerative medicine. This innovative field seeks to provide patients with replacement body parts.

These parts are not made of steel; they are the real things --- living cells, tissue, and even organs.

Regenerative medicine is still mostly experimental, with clinical applications limited to procedures such as growing sheets of skin on burns and wounds. One of its most significant advances took place in 1999，when a research group at North Carolina’s Wake Forest Institute for Regenerative Medicine conducted a successful organ replacement with a laboratory-grown bladder. Since then, the team, led by Dr. Atala, has continued to generate a variety of other tissues and organs 一 from kidneys to ears.

The field of regenerative medicine builds on work conducted in the early twentieth century with the first successful transplants of donated human soft tissue and bone. However, donor organs are not always the best option. First of all, they are in short supply, and many people die while waiting for an available organ; in the United States alone, more than 100,000 people are waiting for organ transplants. Secondly, a patient’s body may ultimately reject the transplanted donor organ. An advantage of regenerative medicine is that the tissues are grown from a patient’s own cells and will not be rejected by the body’s immune system.

Today, several labs are working to create bioartificial body parts. Scientists at Columbia and Yale Universities have grown a jawbone and a lung. At the University of Minnesota, Doris Taylor has created a beating bioartificial rat heart. Dr. Atala’s medical team has reported long-term success with bioengineered bladders implanted into young patients with spina bifida (a birth defect that involves the incomplete development of the spinal cord). And at the University of Michigan, H. David Humes has created an artificial kidney.

So far, the kidney procedure has only been used successfully with sheep, but there is hope that one day similar kidney will be implantable in a human patient. The continuing research of scientists such as these may eventually make donor organs unnecessary and, as a result, significantly increase individuals’ chances of survival.

1. In the latest field of regenerative medicine, what are replacement parts made of?

A. Donated cells, tissues and organs.

B. Rejected cells, tissues and organs.

Time talks. It speaks more plainly than words. Time in many ways.

Consider the different parts of the day, for example. The time of the day when something is done can give a meaning to the event. It is not a to telephone someone very early in the morning. If you telephone him early in the day, he is shaving or having breakfast, the time of the call shows that something is urgent and immediate attention.

The same meaning is telephone calls made after 11:00 pm. If someone receives a call during sleeping hours, he may think it is a of life or death. The time chosen for the call its importance.

In social life, time plays a very part. In the United States, guests tend to feel they are not highly regarded if the to a dinner party is extended only three or four days before the party date. But this is not in all countries. In other areas of the world, it may be considered foolish to make an appointment too far because plans which are made for a date more than a week away tend to be .

The meaning of time from place to place in the world. , misunderstandings often arise between people from different cultures that time differently. For example, promptness (准时) is greatly in American life. If people are not prompt, they may be regarded as or not fully responsible. In the US, no one would think of keeping a business partner for an hour; it would be too rude. A person who is five minutes late is to make a short apology.

To most people, noise pollution is a jet flying over their head. For one Spanish woman, it is a neighbor playing the piano. The woman has taken her neighbor to court. Now she wants to send her neighbor to prison for over seven years on the charges of psychological damage and noise pollution.

In a country known for its noisiness, the case has raised eyebrows. Neighbors often complain about street noise in Spain, but people seeking prison time for someone practicing the piano is unheard of. At the trial, Sonia Bosom says she has been suffering noise pollution up to now due to the practice sessions of Laia Martin, who lives below her. Martin, 27, didn’t admit that she played at home that often, saying she took regular classes in other towns and mostly practiced at home on the weekends.

On the first day of the trial, the newspaper reported that Bosom told the court she now hated pianos so much that she couldn’t even stand seeing them in a film.

Bosom says years of hearing constant playing has caused her “psychological injury”. Medical reports show she has suffered from a variety of problems, including insomnia (失眠), anxiety, and panic attacks.

She says tests by local authorities have found that the sound levels made by the piano are up to 10 decibels (分贝) higher than the limit. City authorities have asked the family several times to either stop the piano playing or soundproof (隔音) the room. The family told the court they carried out soundproofing work twice but the complaints continued.

The court hasn’t made a final decision. A spokeswoman says the trial will end before May.
