    If cars had wings，they could fly and that just might happen，beginning in 2011.The company Terrafugia，based in Woburn，Massachusetts，says it plans to deliver its car­plane，the Transition，to customers by the end of 2011.

    “It's the next ‘wow' vehicle，” said Terrafugia vice president Richard Gersh.“Anybody can buy a Ferrari，but as we say，Ferraris don't fly.”

    The car­plane has wings that unfold for flying－a process the company says takes one minute－and fold back up for driving. A runway is still required to take off and land.

    The Transition is being marketed more as a plane that drives than a car that flies，although it is both. The company has been working with FAA to meet aircraft regulations，and with the National Highway Traffic Safety Administration to meet vehicle safety regulations.

    The company is aiming to sell the Transition to private pilots as a more convenient and cheaper way to fly. They say it saves you the trouble from trying to find another mode of transportation to get to and from airports：You drive the car to the airport and then you're good to go. When you land，you fold up the wings and hit the road. There are no expensive parking fees because you don't have to store it at an airport－you park it in the garage at home.

    The car­plane is designed to fly primarily under 10,000 feet. It has a maximum takeoff weight of 1,430 pounds，including fuel and passengers. Terrafugia says the Transition reduces the potential for an accident by allowing pilots to drive under the bad weather instead of flying into marginal(临界的) conditions.

    The Transition's price tag：$194,000.But there may be additional charges for options like a radio，a transponder or a GPS. Another option is a full­plane parachute.

    “If you get into a very awful situation，it is the necessary safety option，” Gersh said.

    So far，the company has more than 70 orders with deposits. “We're working very closely with them，but there are still some remaining steps，” Brown said.

    Pat O'Burke was a poor Irishman with a large family, and one morning, waking up very early from cold and hunger, he decided to go shooting in a wood near his cottage. The wood belonged to Lord Northwood, a rich gentleman. Pat had no right to go there, but in it there were swarms of rabbits and flocks of birds that were good to eat, and Pat determined to take the risk. Suddenly he saw the owner, with a group of friends, coming towards him in the wood. There was a look of anger on Lord Northwood's face as he caught sight of the gun in Pat's hands.

    Pat's heart sank with fear, but he saw there was no hope of escape, so he walked boldly(大胆) up to the group and said to Lord Northwood, “Good morning, sir, and what has brought you out so early this morning?”

    Lord Northwood, rather surprised, said he and his friends were taking a little exercise to get an appetite(食欲) for their breakfast. Then, looking at Pat with suspicion(怀疑), he said, “but why are you out so early in the morning?”

    “Well, sir” said Pat, “I just came out to see if I could get a breakfast for my appetite.”

    The whole crowd burst into laughter at Pat's ready wit, and with a smile Lord Northwood walked on, leaving Pat to try his luck with the rabbits.

    Safety in the highway is not totally out of our hands. Here are four ways we can protect ourselves when we travel.

    {#blank#}2{#/blank#} people in small cars are injured more often and more severely than people traveling in large cars. Factories of small cars are strengthening their products' safety, which helps. But the mix of large cars and small cars on the road is the main reason of the problem.

    Being thrown into glass and mental cars parts, or being thrown from the car can really hurt or even kill you.

    {#blank#}3{#/blank#}The safety belt's main purpose is to pull you back if your car has a sudden crash with another vehicle or object, or if it rolls over. A belt can reduce the chance of deadly injury by 45% and the chance of serious injury by 50%.

    Air bags are important. More than half of all new cars sold have air bags. Air bags provide protection in frontal crashes—the type of crash that kills the most drivers—when they are also wearing safety belts. Most people are demanding air bags in the cars they buy.  {#blank#}4{#/blank#} Effective as they are, they can't take the place of safety belts.

    Drunk driving crashes are less likely to happen if you don't drink. {#blank#}5{#/blank#}Many people have realised that drunk driving can lead to death and injury, prison time and other results. There are movements to strengthen penalties(处罚) for drinking and driving.

A. How to drive safely?

B. You are safer in a large car

C. How to protect ourselves in the highway?

D. Air bags are not installed in all cars.

E. That's why safety belts should be worn.

F. Drunk driving is the most serious problem.

G. But the protection provided by air bags is limited in side or rear crashes.

    There is no doubt that many parents want to mold (塑造)their child to be better, faster, smarter and more skilled. Even though human parents can't do that, a robot that builds its own children can. Scientists at the University of Cambridge in England have created a mother robot that not only creates its own children, but tests out their performance.

    The mother robot analyzes(分析)the performance of each of the “children” it creates, and passes down good characters to the next generation

    For example, as the mother creates them and puts them to work, she measures how they're behaving, and she uses data from this behavior to create the next generation of robots.

    The mother robot can actually build hundreds of child robots and see the performance of these child robots. And if their performance is good, keep their design for the next generation. And if bad, just let it go.

    “We program the robots based on some functions that define(规定)the reward the robots are going to get, depending on the construction that they make. They cannot change their own reward. For the child robot, the longer the distance the robot walks, the better the reward it receives,” said Fumiya Iida, the lead researcher.

    After several generations, the “children” were running twice as fast.

    “The mother robot produced 500 robots to see which one is good and which one is bad,” said Iida.

    The researchers believe that the machines can be used in a car factory, for example, where robot cameras examine each ear in production line, find out any mistakes, and then design a better car.

    People seem to have a natural need for friends and with good reason, friends increase your enjoyment of life and relieve feelings of loneliness. They even can help reduce stress and improve your health. Having good friends is especially helpful when you are going through any kind of hard time such as when you are experiencing anxiety, panic(恐慌) attacks, or depression.

    When you are with good friends, you feel good about yourself, and you are glad to be with them. A friends is someone who—

●you like, respect, and trust, and who likes, expects and trusts you, doesn't always understand you, but accepts and likes you as you are, even as you grow and change, allows you the space to change, grow, make decisions, and even make mistakes.

●listens to you and shares with you both the good times and the bad times.

●respects your need for secrets, so you can tell them anything.

●lets you freely express your feelings and emotions without judging, laughing at or criticizing you.

●accepts the limitations you have put on yourself and helps you to remove them.

    A person once said. "Friendship is a continuing source of bonding(连接),releasing, and creating in yourself and with the other person, there is an emotional bond between the two people."

    A good friend or supporter may or may not be the same age or the same sex as you, and may not have the same educational, cultural, or religious background, or share interests that are similar to yours. Friendships also have different depths(深度). Some are closer to the heart and some more superficial, but they're all useful and good.

    I was in the middle of the Amazon (亚马逊) with my wife, who was there as a medical researcher. We flew on a small plane to a faraway village. We did not speak the local language, did not know the customs, and more often than not, did not entirely recognize the food. We could not have felt more foreign.

    We were raised on books and computers, highways and cell phones, but now we were living in a village without running water or electricity It was easy for us to go to sleep at the end of the day feeling a little misunderstood.

    Then one perfect Amazonian evening, with monkeys calling from beyond the village green, we played soccer. I am not good at soccer, but that evening it was wonderful. Everyone knew the rules. We all spoke the same language of passes and shots. We understood one another perfectly. As darkness came over the field and the match ended, the goal keeper, Juan, walked over to me and said in a matter-of-fact way, "In your home, do you have a moon too?" I was surprised.

    After I explained to Juan that yes, we did have a moon and yes, it was very similar to his, I felt a sort of awe (敬畏) at the possibilities that existed in his world. In Juan's world, each village could have its own moon. In Juan's world. the unknown and undiscovered was vast and marvelous. Anything was possible.

    In our society, we know that Earth has only one moon. We have looked at our planet from every angle and found all of the wildest things left to find. I can, from my computer at home, pull up satellite images of Juan's village. There are no more continents and no more moons to search for, little left to discover. At least it seems that way.

    Yet, as I thought about Juan's question, I was not sure how much more we could really rule out. I am, in part, an ant biologist, so my thoughts turned to what we know about insect life and I knew that much in the world of insects remains unknown. How much, though? How ignorant (无知的) are we? The question of what we know and do not know constantly bothered me.

    I began collecting newspaper articles about new species, new monkey, new spider…, and on and on they appear. My drawer quickly filled. I began a second drawer for more general discoveries: new cave system discovered with dozens of nameless species, four hundred species of bacteria found in the human stomach. The second drawer began to fill and as it did I wondered whether there were bigger discoveries out there, not just species, but life that depends on things thought to be useless, life even without DNA. I started a third drawer for these big discoveries. It fills more slowly, but all the same, it fills.

    In looking into the stories of biological discovery, I also began to find something else, a collection of scientists, usually brilliant occasionally half-mad, who made the discoveries. Those scientists very often see the same things that other scientists see, but they pay more attention to them, and they focus on them to the point of exhaustion (穷尽), and at the risk of the ridicule of their peers. In looking for the stories of discovery, I found the stories of these people and how their lives changed our view of the world.

    We are repeatedly willing to imagine we have found most of what is left to discover. We used to think that insects were the smallest organisms (生物), and that nothing lived deeper than six hundred meters. Yet, when something new turns up, more often than not, we do not even know its name.
