Hank Viscardi was born without legs. He had not legs but stumps(残肢)that could he fitted with a kind of special boots. People stared at him with cruel interest. Children laughed at him and called him ‘Ape Man’ (猿人) because his arms practically dragged on the ground.

Hank went to school like other boys. His grades were good and he needed only eight years to finish his schooling instead of the usual twelve. After graduating from school, he worked his way through college. He swept floors, waited on table, or worked in one of the college offices. During all this busy life, he had been moving around on his stumps. But one day the doctor told him even the stumps were not going to last much longer. He would soon have to use a wheel chair.

Hank felt himself getting cold all over. However, the doctor said there was a chance that he could be fitted with artificial legs (假腿). Finally a leg maker was found and the day came when Hank stood up before the mirror, for the first time he saw himself as he has always wanted to be-a full five feet eight inches tall. By this time he was already 26 years old.

Hank had to learn to use his new legs. Again and again he marched the length of the room, and marched back again. There were times when he fell down on the floor, but he pulled himself up and went back to the endless marching. He went out on the street. He climbed stairs and learned to dance. He built a boat and learned to sail it.

When World War II came, he talked the Red Cross into giving him a job. He took the regular training. He marched and drilled along with the other soldiers. Few knew that he was legless. This was the true story of Hank Viscardi, a man without legs.

I know that something you get that sense from TV that you can be rich and successful without any hard work---your ticket to success is through rapping or basketball or being a reality TV star . 1.

The truth is, being successful is hard. You won’t love every subject that you study. 2. Not every homework assignment will seem completely relevant to your life right at this minute. And you won’t necessarily succeed at everything the first time your try.

That’s okay. 3. JK Rowling---- who wrote Harry Potter---her first Harry Potter book was rejected 12 times before it was finally published. Michael Jordan was cut from his high school basketball team. He lost hundreds of games and missed thousands of shots during his career. But he once said, “I have failed over and over again in my life. And that’s why I succeed.

These people succeeded because they understood the secret of success ---you can’t let your failures define you. 4. You have to let them show you what to do differently the next time. So if you get into trouble, that doesn’t mean you are a troublemaker, it means you need to try harder to act right. 5.

A. If you get a bad grade, that doesn’t mean you’re stupid, it just means you need to spend more time studying.

B. Some of the most successful people in the world are the ones who have had the most failures.

C. You have to let your failures teach you.

D. You won’t get along well with every teacher that you have.

E. So many of you dream of being successful by hard work.

F. Failures can lead you to success.

G. Chances are you’re not going to be any of those things.

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.

C. Cells, tissues and organs of one’s own.

D. Cells, tissues and organs made of steel.

2. What have scientists experimented successfully on for a bioartificial kidney?

A. Patients. B. Rats. C. Sheep. D. Soldiers.

3.Why is generative medicine considered innovative?

A. It will provide patients with replacement soft tissues.

B. It will strengthen the human body’s immune system.

C. It will shorten the time patients waiting for a donated organ.

D. It will make patients live longer with bioartificial organs.

4. What is the writer’s attitude towards regenerative medicine?

A. Positive. B. Negative.

C. Doubtful. D. Reserved.

As more people use smart phones to pay bills and store personal information, strict password security has become more important than ever. A new study shows that free - form gestures – sweeping fingers in shapes across the screen of a smart phone—can be used to unlock phones. These gestures are less likely to be observed and reproduced by others than traditional typed passwords.

“All that it takes to steal a password is a quick eye,” said one of the researchers of the study. “With all the personal information we have on our phones today, improving their security is becoming increasingly necessary.” In developing a secure solution to this problem, the researchers studied the practicality of using free - form gestures. With the ability to create any shape in any size and location on the screen, the gestures were popular as passwords. Since users create them without following a template, the researchers predicted these gestures would allow for greater complexity.

The researchers carried out a create - test - retest experiment where 63 people were asked to create a gesture, recall it, and recall it again 10 days later. The gestures were captured on a recognizer system designed by the team. Using this data, they tested the complexity and accuracy of each gesture using information theory. The result of their analysis is that people are favorable to use free - form gestures as passwords.

To put their analysis into practice, the researchers then had seven students in computer science and engineering, each with considerable experience with touchscreens（触摸屏）, attempt to steal a free - form gesture password by observing a phone user secretly. None of them were able to copy the gestures with enough accuracy. The gestures appear to be extremely powerful against attacks.

Though the testing is in its early stage and widespread adaptation of this technology is not yet clear, the research team plans to continue to analyze the security and management of free – form passwords in the future. They believe this is the first study to explore free - form gestures as passwords. They will soon publish their findings.

1.What can we learn about free - form gestures?

A. They are improving mobile security in a way.

B. Users will have to make use of simple gestures.

C. They will never be copied by others.

D. Users must move their fingers in fixed shapes.

2.The experiment in paragraph 4 is to test _________ of free - form gestures.

A. template B. application

C. accuracy D. security

3. According to the text, the researchers think that ________.

A. it is easy to steal any password with a quick eye

B. better ways of setting passwords should be developed

C. people had better not use smart phones to pay bills

D. personal information should not be stored in a phone

4.The main purpose of the text is to ________.

A. advise people to use free - form gestures

B. discuss whether smart phones are safe

C. talk about the practicality of passwords

D. introduce the study of a new password

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.

1.Bosom wants to send Martin to prison because _______.

A. Martin’s playing the piano damaged her health

B. Bosom suffered from heart attack

C. Martin refused to take regular classes in other towns

D. Martin flew a jet over her head

2.How did Laia Martin respond to the complaints?

A. She stopped playing the piano.

B. She soundproofed the room.

C. She didn’t admit she played at home.

D. She took her neighbor to court.

3.Which of the following may probably be the best title for the passage?

A. A 7-year Sentence Caused by the Piano

B. Pianist Charged with Noise Pollution

C. Health Problems of a Spanish Woman

D. Actions Against Noise by Local Authority
