ScienceDaily (May 28, 2010) --- Researchers at Oregon State University (OSU) have made important progress in work that should lead toward robots that can not only walk and run very well, but use little energy at the same time.
Studies are moving closer to designing robots that could do dangerous work, create prosthetic limbs（假肢）for humans that work much better than in the past, or even help some people who use wheelchairs to get “walking” abilities.
“Researchers have been working toward robot movement for a long time,” said Jonathan Hurst, a professor at OSU. “What we’ve done is to study what behavior is really possible for a robot.”
The movement of humans and other animals is difficult to copy. Using little energy, they can move easily over hard areas, and enjoy balance from muscles（肌肉）. They have different ways to deal with forces, such as holding something hard in place rigidly（牢牢地）, like the act of holding a cup of coffee level during a car ride. In their recent studies, the OSU researchers proved that these two abilities are mutually exclusive（相互排斥的）. Humans deal with this problem by using pairs of muscles. For a robot, the more it’s able to do one of these tasks, the less able it is to do the other.
Presently, robots that can walk and run must be as rigid as possible while walking. But this way uses a lot of energy. The OSU researchers are working toward something that has similar or better performance, but uses far less energy, and is closer to the abilities of animals.
“So there’s no reason why we shouldn’t be able to build robots with good movement ability,” Hurst said. “Clearly this might be useful in highly dangerous situations. But I could also see great improvements possible with prosthetic limbs that work much better than present technology. ”

“A child in the street is a child that has been exposed（暴露）to a lot of bad things. And this child has no love at all. This child has no respect（尊重）for himself or herself. He sees everybody as an enemy, and he can’t trust anyone.”
Who is Moses Zulu talking about? Are there even people who live like that? Sadly, in truth, there are. They happen to be the Zambian children that Moses Zulu helps to improve their lives. Zulu does his best to give many children the hope to live even though they might have AIDS. Without his continuous work through his organization called Children’s Town, many Zambian children would have been forced to survive（生存）in an African city by getting a job as a street vendor（街头小贩）, or hurting other people.
In 1990, Moses Zulu founded Children’s Town in Zambia, where one million children have no parents, largely because of AIDS. Children’s Town teaches children the basic life skills needed for their future. Each child goes through a five-year training program where they’re taught responsibility（责任）, values, and self-care. Zulu’s Children’s Town provides hope for less fortunate children.
As we all know, a hero is any person who is respected for their qualities and achievements. There are not many people who are willing to help others in need. Zulu’s contribution to today’s modern society teaches us to lend a helping hand to others who are not as lucky as we are. He teaches us to make a difference in the world by helping others.
And from now on, if ever you throw away your banana just because it looks bad, well, remember that a group of people suffering from AIDS, homelessness, or other causes, would fight each other just to get their hands on a single bad banana.

71. 4. In the last paragraph, the author advises us to ______.
A. plant more bananas B. make use of bad food
C. invent medicine for AIDS D. help poor people

President Bush’s dogs often play on the White House lawn（草坪）, but did you know that he also has cows and a cat? His cat is named India. India, also called “Willie”, has lived with the Bush family for more than ten years! On his farm in Crawford, Texas, he keeps a cow called Ofelia named after a person who worked with him when he worked in Texas.
Past Presidents brought many interesting animals to the White House. The wife of John Quincy Adams, the sixth President, had silkworms. Herbert Hoover, the 31st President, had an opossum（负鼠）. And Calvin Coolidge, the 30th President, had a raccoon（浣熊）named Rebecca.
Theodore Roosevelt, the 26th President, was famous for his many pets. His six kids had snakes, dogs, cats, a badger, birds, guinea pigs, and more.

Levi Strauss was born in Bavaria (巴伐利亚) in Europe in 1829. He emigrated（移居）to the United States of America when he was seventeen years old. His brothers sold cloth, and he worked for them even though he could not speak English very well. At this time many people were moving to California because gold was discovered there. Strauss went to look for gold, too.
Strauss took a lot of cloth with him to San Francisco. He thought that he could make tents out of the cloth and sell them to people working in the gold fields. But when he got there, he saw that people had a greater need for clothes than tents. Clothes did not last very long in the gold fields. At first Strauss made pants out of canvas（帆布）. They were very strong ---- much stronger than other pants. Soon everyone was wearing them , so he decided only to make pants. He opened a small store and made a lot of money from selling pants.
After a while, Strauss found a material even stronger than canvas. It came from a town in France called Nimes. The French called the material serge de Nimes, which means “cloth from Nimes”. The Americans called it denim. Strauss also bought some cloth from Genoa, a town in Italy. To Americans this name sounds like “jeans”, so they called his pants jeans. The cloth that Strauss used was always blue, so people also called his pants blue jeans and blue denims. Other people called them Levi’s. Levi Strauss jeans are some of the best-selling jeans in the world today. They last a long time and are very comfortable.
