    Traditionally, robots have been hard, made of metal and other rigid material. But a team of scientists at Harvard University in the US has managed to build an entirely soft robot-one that draws inspiration from an octopus (章鱼).

    Described in science journal Nature, the "Octobot" could pave the way for more effective autonomous robots that could be used in search,rescue and exploration. "The Octobot is minimal system which may serve as a foundation for a new generation of completely soft, autonomous robots" the study's authors wrote.

Robots built for precise, repetitive movements in a controlled environment don't do so well on rough terrains (地形) or in unpredictable conditions. And they aren't especially safe around humans, because they're made out of hard and heavy parts that could be potentially dangerous to their users.

    So researchers have been working on building soft robots for decades. They're taken inspiration from nature, looking to animals from jellyfish to cockroaches, which are often made up of more flexible matter.

    But creating a completely soft robot remains a challenge. Even if engineers build a silicone (硅酮) body, it's still a grand challenge to construct flexible versions of essential parts, such as a source of power.

    "Although soft robotics is still in its early stage, it holds great promise for several applications, such as search-rescue operations and exploration," Barbara Mazzolai and Virgilio Mattoli of the Italian Institute of Technology' Center for Micro-BioRobotics, wrote in a comment. "Soft robots might also open up new approaches to improving wellness and quality of life."

(1)、What's the special feature of "Octobot"?
A、It's soft. B、It's made of metal. C、It's very small. D、It looks like an octopus.
(2)、What's the disadvantage of traditional robots?

(3)、One of the biggest challenges is to build Octobot's ________.
A、silicone body B、complex components C、precise movements D、flexible power source
(4)、What's the possible application of "Octobot"?
A、Medical research. B、Life rescue. C、Machine operation. D、House cleaning.

        Since the day of its birth, the United Nations has been the subject of much debate.

{#blank#}1{#/blank#} Others think that it is too weak. We can better understand this debate if we learn more about the U.N. and its history.

        The U.N. was started for two reasons. First, when the idea wasborn, people all over the world were tired of war. They felt that there must be peaceful answers to the world's problems.

{#blank#}2{#/blank#}

        The second reason was that modern science had developed newbombs and airplanes.

{#blank#}3{#/blank#} National borders were beginning to lose theirmeaning. Science would develop even more dangerous weapons in the future. Onlyan international organization would be able to control modern science.

        Franklin D. Roosevelt, U.S. President at the time, believed thatthe Allies (联盟) should plan for peace before the war ended. On December 1, 1943, Roosevelt, Britain's Winston Churchill and Joseph Stalin from Soviet Union agreed to start anorganization for world peace.

{#blank#}4{#/blank#}

        During the next year and a half, the idea of such anorganisation was debated around the world. Then came the big day. On April 11,1945, the first international meeting of the United Nations took place in SanFrancisco. The goal of the meeting was to write the U.N. Charter (宪章). All of thefifty-one nations at the meeting had their own ideas to offer for the Charter.

{#blank#}5{#/blank#} Every nation present voted for the Charter. Noone voted against it.

A. The U.N. Charter is a beautiful piece of writing.

B. After a long debate, a final Charter was agreed upon.

C. Even the smallest country on earth can have its voice heard.

D. They asked all countries, large and small, to join theorganization.

E. These weapons made it almost impossible for a country todefend itself.

F. Some people attack the organization because they think it istoo powerful.

G. They also felt that only an international organization couldkeep world peace.

    Chinese are very generous when it comes to educating their children. Not caring about the money, parents often send their children to the best schools or even abroad to England, the United States or Australia. They also want their children to take extra-course activities where they will either learn a musical instrument or ballet, or other classes that will give them a head start in life. The Chinese believe that the more expensive an education is, the better it is. So parents will spend an unreasonable amount of money on education. Even poor couples will buy a computer for their son or daughter.

    However, what most parents fail to see is that the best early education they can give their children is usually very cheap. Parents can see that their children's skills vary, skilled in some areas while poor in others. What most parents fail to realize though, is that today's children lack self-respect and self-confidence. The problem is that parents are only educating their children on how to take multiple-choice tests and how to study well, but parents are not teaching them the most important skills they need to be confident, happy and clever.

    Parents can achieve this by teaching practical skills like cooking, sewing and doing other housework.

    Teaching a child to cook will improve many of the skills that he will need later in life. Cooking demands patience and time. It is an enjoyable but difficult experience. A good cook always tries to improve his cooking, so he will learn to work hard and gradually finish his job successfully. His result, a well-cooked dinner, will give him much satisfaction and a lot of self-confidence.

    Some old machines, such as a broken radio or TV set that you give your child to play with will make him curious and arouse his interest. He will spend hours looking at them, trying to fix them; your child might become an engineer when he grows up. These activities are not only teaching a child to read a book, but rather to think, to use his mind. And that is more important.

An aspirin a day keeps the doctor away

    Dr. Tim Johnson discusses evidence of a daily dose of aspirin's benefits. That's not the saying, but doctors have agreed, for about a generation, that an aspirin a day is good for you. It may reduce the risk of heart attacks or strokes by 20 percent or more.

    The US Preventive Services Task Force, an independent group convened by the Department of Health and Human Services, has published guidelines that it says should end the confusion.

    The key points:

    ⒈Men should start a daily aspirin at age 45, mainly to protect against heart attacks.

    ⒉Women should start at 55, mainly to protect against stroke.

    ⒊For both sexes, a baby aspirin-typically 81 milligram a day-will do the job. There is no evidence that a large dose makes a difference.

    ⒋And both sexes should stop by age 80, unless their doctors say otherwise. As you get older, there's a greater risk of bleeding in the brain or the digestive system, a risk that is small but can be deadly in some cases.

    If people start taking aspirin as the guidelines, doctors say their risk of heart attacks will drop by about 20 percent. "People may ask themselves 'Am I at risk for a heart attack or a stroke?'" said Dr. Randal Thomas, director of cardiovas-cular health at the Mayo Clinic in Minnesota "If you are age 45 and male, if you're above age 55 and female, the answer is most likely yes, and you will most likely benefit from taking a small dose of aspirin a day.

    Rock climbing is not just for grown-ups. Your children can also enjoy this fun-filled activity as well as getting its advantages. Aside from its heart-health benefit, it is also known to increase their self-confidence and esteem(尊重). While it may not be an impromptu(即兴的) activity like running or biking, there are many climbing walls that are now available, especially with the development of fitness centers and camps.

    The great thing about having your kids join these activities is that it follows up on their natural quality. As you know, children are natural climbers. You can see them going up on trees or climbing tall ladders. With rock climbing, you can satisfy their urges to be a climber.

    What's more, it is fairly easy for the kids compared with adults. With a high strength-to-weight rate, they have less body weight to pull up, and they are more flexible(灵活的).

    It is also a low-impact workout that tests your children's endurance(耐性). It's easy on their joints(关节) as they burn energy during their ascent. In addition, climbing walls are like giant puzzles begging to be solved. Not only does it test the physical aspects of your children's development, but it also wakes their mental abilities.

    This exercise also helps develop your children's essential strength and flexibility. Kids are challenged physically as they pull, lift, stretch, and twist their way up. This activity also develops their eye-hand coordination(协调) as they perform their climb.

    Almost anyone can do it although it may vary in skill level, namely beginner, intermediate, or advanced. But despite its reputation as an extreme sport, children can do this. One does not need to be super-fit to join a rock climbing class. However, good technique is more necessary than strength when doing this sport.
