WASHINGTON – It’s a great achievement that inspires notions of robots with consciousness and independent minds.
When people or animals get hurt, they can usually compensate for minor injuries and keep limping along, but for robots, even slight damage can make them stumble and fall. However, a recently made robot has demonstrated a novel ability: it can heal its own damage.
The new robot, which looks like a splay – legged, four – footed starfish can sense injury to itself and adapt. That ability sets the new robot apart from earlier machines. Because the robot can recover from unfamiliar places. “There is a need for planetary robotic rovers to be able to fix things on their own,” says Josh Bongard, a professor in the University of Vermont, who is one of the device’s creator. “Robots on other planets must be able to continue their mission without human help if they are damaged and cannot communicate their problem back to Earth.”
A typical robot functions according to a computer program, but the new robot works differently. First, sensors in its four legs observe the robot’s movements and signals to its built – in computer. From the formation it collects, the robot creates its own programs that allow it to adapt to different situations. For example, when the researchers shortened one of the robot’s legs, the smart machine simply adjusted its way of walking – it used three legs instead of four.
The researchers are looking for other places to put the resilient robot to work. One pellicle spot is the ocean floor. That dark and dangerous undersea terrain might be a good choice for a robot the scientists call the Starfish. “We never officially named the robot, but we usually refer to it as the Starfish, even though a real starfish has five rather than four legs,” says Bongard. “Also, a real starfish is much better than our robot at recovering from injury, because it can actually grow its legs again.” Scientists have created robots that help humans in many ways: by exploring space, fighting fires, and even performing surgery.

Celebrated in the city of Munich, Germany, the Oktoberfest, as it is popularly called, is a 3-week festival that takes place in the months of September and October. Also called the largest beer festival in the world, the Oktoberfest gathers about 6 million visitors worldwide every year. Seeing the popularity of the festival, many countries around the world have adapted to what they call their own version of the Oktoberfest. So if you are not able to make it to Germany, you can always enjoy the festival in the areas mentioned below. Don’t miss out on it!

A year ago, I paid no attention to English idioms, though my teacher stressed the importance again and again. But soon, the importance of English idioms was shown in an amusing experience.
One day, I happened to meet an Englishman on the road, and soon we began to talk. As I was talking about how I was studying English, the foreigner seemed to be astonished. Gently shaking his head and shrugging his shoulders, he said, “You don’t say!”“You don’t say!” I was puzzled. I thought, perhaps this is not a proper topic. “Well, I’d better change the topic.” So I said to him, “Well, shall we talk about the Great Wall? By the way, have you ever been there?” “Certainly, everyone back home will laugh at me if I leave China without seeing it. It was wonderful.” He was deep in thought when I began to talk like a tourist guide. “The Great Wall is one of the wonders in the world. We are very proud of it”. Soon I was interrupted again by his words：“You don’t say!” I couldn’t help asking, “Why do you ask me not to talk about it?” “Well, I didn’t request you to do so,” he answered, greatly surprised. I said, “Didn’t you say ‘you don’t say’?” Hearing this, the Englishman laughed to tears. He began to explain, “‘You don’t say’ actually means ‘really?’ It is an expression of surprise. Perhaps you don’t pay attention to English idioms.” Only then did I know I had made a fool of myself. Since then I have been more careful with idiomatic expressions.

Farming is moving indoors, where the sun never shines, where rainfall is irrelevant (无关的) and where the climate is always right. The perfect crop field could be inside a windowless building with controlled light, temperature，humidity，air quality and nutrition. It could be in a New York high- rise or a complex （建筑群） in the Saudi desert. It may be an answer to the world’s food problems.
The world already is having trouble feeding itself. Half the people on Earth live in cities, and nearly half of those – about 3 billion – are hungry or ill–fed. Food prices, currently increasing, are badly affected by dryness, floods and the cost of energy required to plant, harvest and transport it. And prices will only get more unstable. Climate change makes long-term crop planning uncertain. Farmers in many parts of the world already are using water available to the last drop. And the world is getting more crowded: by mid-century, the global population will grow from 6.8 billion to 9 billion.
To feed so many people may require expanding farmland at the expense of forests and wilderness, or finding ways to greatly increase crop output.
Gertjan Meeuws and three other Dutch bioengineers grow vegetables and house plants in closed and regulated environments. In their research station, water flows into the pans when needed, and the temperature is kept constant. Lights go on and off, creating “day” and “night”, but according to the rhythm of the plant.
Meeuws says a building of 100 square meters and layers of plants could provide a daily diet of 200 grams of fresh fruit and vegetables for the entire population of Ken Bosch, about 140,000 people. Their idea isn’t to grow foods that require much space, like corn or potatoes.
Sunlight is not only unnecessary but can be harmful. Plants need only specific wavelengths of light to grow. Their growth rate is three times faster than under greenhouse conditions. They use about 90 percent less water than outdoor agriculture. And city farming means producing food near the consumer, so there’s on need to transport it long distances.According to the text, Gertjan Meeuws’ farming _______.
| A．can be used for corn production |
| B．is much like greenhouse farming |
| C．is adaptable to any environment |
| D．uses more water than outdoor farming |
What is the second paragraph mainly about ?
| A．The effect of climate | B．The hungry people in cities. |
| C．The world’s food problem. | D．The world’s increasing population. |
What is the purpose of the text ?
| A．To compare traditional and indoor farming. |
| B．To discuss the influence of climate change. |
| C．To explain the world’s food problem. |
| D．To introduce a new model of farming. |
Last Sunday, I waked into the house in the afternoon to find my brother rushing around in a hurry. As soon as I took my coat off, my little brother placed a bunch of papers in my hands and asked me to fold them up so they could fit into an envelope as quickly as possible. He said it needed to get done quickly before it turned dark.
I was a little surprised that something could be so urgent on a Sunday. It wasn’t until I was halfway through that I actually looked at what I was folding. After I read it, it put the biggest smile on my face. It was a lovely letter to all the residents （居民）in my neighborhood. My brother was asking everyone to let him know if anyone needed help. He left his contact information and said that anyone that needed help should get in touch with him and he would figure something out. He also asked people to get in touch if they were able to help out.
London received an unusual amount of snow last week, and the city was completely under- prepared for it. So it was quite difficult to get anywhere. Only the major roads had been cleared, and smaller roads and pavements could be quite treacherous. There are a good number of old people in our little community. So my brother thought that the snow may have posed （造成）some difficulty for some of them, particularly because we live on a hill.
A few elderly people got in touch with him asking for help for things they needed. One of them was especially grateful because his caregiver couldn’t make it. To our surprise, he got more responses from people offering to help. Then he received help from people who wanted to help. Everyone was really touched and wrote to my brother wonderful email. One of our neighbors wrote email saying that although she wasn’t able to help, she was “very proud of having a neighbor like him who puts other people’s interests first.”The author’s brother wrote the letter to _______.
| A．ask for help from his neighbors |
| B．give a hand to those in need of help |
| C．require his neighbors to clear the snow |
| D．raise money for the old people in his community |
What can we learn from the text?
| A．Few people were willing to help out. |
| B．The snow was unexpectedly heavy. |
| C．Most residents in the community are elderly people. |
| D．The community was completely cut off from the outside world. |
The underlined word “treacherous” in Paragraph 3 probably means “_______”.
| A．dirty | B．dangerous | C．safe | D．crowded |
One of their neighbors sent email to the author’s brother to ________.
| A．express thanks | B．lend a hand |
| C．show appreciation | D．ask for help |
Dear Bridge of Hope supporters,
July 2010 was a productive month for the teachers at BOH. Marilyn traveled to Liberia and helped Kathleen Ngenda with her teacher training program on Basic Adult Literacy. During the eight-day training, she helped the teachers learn to pronounce, spell and write correctly. They are currently working on personal sets of cards and lists so that they can teach this concept to students in the fall. Kathleen plans on two trips back to the school to monitor teachers in their teaching.
Marilyn found a very dedicated （投入的）and enthusiastic group of elementary teachers who are focused on bettering themselves as educators. BOHUSA will offer financial support for their further educational studies this fall. Our goal is to have all staff be certified by the end of 2013.
The Liberian government recommends a C-certificate for teachers of elementary students, which can be obtained in one year of education classes (taken on Saturdays).
There is a great need to add seventh and eighth grade classrooms and a library. There is actually no room, however, and so we need to add a second floor. Currently the ground floor houses the church and the school uses this space for daily services. The first floor would give space for three more classrooms, in addition to a large reading room and computer labs. About $40,000 to 50,000 is required to meet the educational needs.
