A team of researchers recently created a robot that can repair itself. The newly designed machine can sense injury to itself and adapt. That ability sets the new robot apart from earlier machines. Because the robot can recover from unexpected damage, it may be especially useful in exploring unfamiliar places. “There is a need for planetary robotic rovers(流浪者) to be able to fix things on their own,” says Josh Bongard, one of the device’s creators. “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 information 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(迅速恢復(fù)) robot to work. One possible spot is the ocean floor. That dark and dangerous undersea terrain(地帶) 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 regrow its legs.” Scientists have created robots that help humans in many ways: by exploring space, fighting fires, and even performing surgery.
1. The newly designed robot is different from the former ones because it ___________.
A. can communicate with people on the earth about their problems
B. works according to a certain computer program
C. can find problems itself and get used to the new environment
D. can explore unfamiliar places
2. An example is given in the second paragraph in order to explain that the new robot ___________.
A. is used to create new programs                        B. has typical robot functions
C. has sensors to observe its movements              D. can adapt to new conditions
3. What might be the best title of the passage?
A. How does the Starfish Robot work                B. Do-It-Yourself Robot Repair
C. Robots Designed to Work On Other Planets    D. New Robot Helping Us In Many Ways
4. Which of the following is True about the Starfish?
A. It has more than four legs.                               B. It hasn’t been officially named.      
C. It can regrow its legs quickly.                    D. It has started to work on the ocean floor.

Yesterday's paper had a short article about the Coming-of-Age ceremony in a large city in Japan. According to the article, the mayor of the city formally apologized to an enraged professor who delivered a speech at the ceremony that was all but ignored by 20-year-olds in the city.
The officials prepared 7,000 seats in a gymnasium where the ceremony was held for the 17,000 twenty-year-olds residing in the city. But most of the seats were empty during the speech. And many of the 20-year-olds who did show up ignored the professor and spoke among themselves or talked on their mobile phones. Some even made a ruckus (騷動(dòng)) outside the gymnasium.
One 20-year-old who attended the ceremony said youngsters came to the ceremony not to
listen to speeches but to see their classmates. The mayor criticized the young generation at a news conference on Tuesday, saying such behavior "is symbolic of the postwar era which failed to
nurture healthy character and social intelligece."
Personally I feel people should not generalize the whole generation or the whole era when he criticizes something. But it is also true generation gap is getting bigger and bigger regarding the ceremony of Coming-of-Age Day. So far this ceremony has been held with citizens' tax money. Many older generations understand this festival as an entrance ceremony of adults' world which requires maturity including responsibility, patience, and cooperativeness. Older people tend to be "educational" to younger ones, while younger people tend to feel they finally obtain a right to behave freely because they are now adults. Though, ironically, young people have to ask their parents to buy them new clothes for the ceremony.
It is about time to change the way we celebrate this festival, I think. The idea of blessing new 20-year-olds is not so bad. But there seems to be some other ways to celebrate more properly. The present way seems to me a little superficial and materialistic. It can provide solutionless arguments between different generations, instead of friendships and respects. Instead of eternally complaining about the young's behaviors at the ceremonies, people should consider how they can make their ceremonies worthier, I feel.
1．We can infer from the passage that 
A．in Japan, girls and boys, when they are 20 years old, come to their adulthood
B．there are 7,000 twenty-year-olds residents in the city
C．the mayor criticized the young generation at a news conference
D．it’s about time to change the way we celebrate the Coming-of-Age
2．When the professor was giving a speech the 20-years-olds are NOT________.
A．talking with each other               B．chatting on their mobile phones
C．talking with the professor             D．making ruckus outside
3．According to the author _________
A．the festival is an entrance ceremony of adults’ world which requires maturity including responsibility, patience, and cooperativeness
B．the young people tend to obtain a right to behave freely because they are now adults
C．young people have to ask their parents to buy them new clothes for the ceremony
D．it’s time to end complaining about the young’s behaviors at the ceremonies, and people should consider how to make their ceremonies worthier
4．What’s the best title for the passage
A．There are solutionless arguments between different generations.
B．Coming-of-Age ceremony should be much worthier.
C．Old people should be educational to young people
D．The younger ones’ behaviors stand for an era which failed to nurture healthy character and social intelligence

Farmers use different kinds of soil conservation methods to protect their land from damage by farming and the forces of nature . One important form of soil conservation is the use of windbreaks . Windbreaks are barriers formed by trees and other plants with many leaves . Farmers plant them in lines around their fields .
Windbreaks stop the wind from blowing soil away . They also keep the wind from destroying or damaging crops . They are very important for growing grains , such as wheat . There have been studies done on windbreaks in parts of West Africa , for example . These found that grain harvests can be twenty percent higher in fields protected by windbreaks compared to fields without such protection .
However , windbreaks seem to work best when they allow a little wind to pass through . If the wall of trees and plants stops wind completely , then violent air motions will take place close to the ground . These motions will lift soil into the air where it will be blown away .
For this reason , a windbreaks is best if it has only sixty to eighty percent of the trees and plants needed to make a solid line . An easy role to remember is that windbreaks can protect areas up to ten times the height of the tallest trees in the windbreaks .
These should be at least two lines in each windbreak . One line should be large trees . The second line , right next to it , can be shorter trees and other plants with leaves . Locally grown trees and plants are best for windbreaks .
1.What is the best title for the passage?
A.Building a windbreak to protect soil
B.Building a windbreak to protect crops
C.Using a windbreak to improve grains
D.Using a windbreak to improve plants
2.In the fifth paragraph the author tells us windbreaks______.
A.do not work at all
B.do not stop wind fully
C.will not take place
D.will not allow wind to pass through
3.According to the passage , which of the following statement is wrong ?
A.Windbreaks are barriers .
B.Windbreaks can be used to make fences .
C.In general , there are two lines in all in every windbreak .
D.Windbreaks can protect areas .

The Story of the Farmer and His Donkey (驢子)
One day a farmer’s donkey fell down into a well. The animal cried pitifully for hours as the farmer tried to figure out what to do. Finally he decided the animal was old, and the well needed to be covered up anyway and it just wasn’t worth to save the donkey. So, he decided to bury（埋） it!
He invited all his neighbors to come over and help him. They all took shovel（鏟子）and began to shovel dirt into the well. At first, the donkey realized what was happening and cried horribly, then slowly he quieted down till nothing more was heard.
A few shovels later, the farmer finally looked down into the well, and was surprised at what he saw. With every shovel of dirt that hit his back, the donkey was doing something wonderful—he would shake it off and take a step up!
As the farmer’s neighbors continued to shovel dirt on top of the animal, he would shake it off and take a step up. Pretty soon, everyone was surprised as the donkey stepped up over the edge of the well and went off quickly!
