British scientists have been given ￡ 1 million by the European Commission to find out if a robot (机器人) can safely be employed to stir (搅拌) soup.The research, based at the Bristol Robotics Lab (BRL), will look at the problems of a human and a robot working together in the same space; for example, in a kitchen where the service robot is performing a task such as stirring soup while you add cream.Professor Chris Melhuish explained, "When we work with other humans, we are trying to understand facial expression, body movements, quality of voice, as well as sharing a goal and understanding and following spoken instructions. ""For example, in the soup situation, not only does the robot need to know what the goal is ( making the soup) but he also needs to know how hard to stir the soup, what it means when you hold up your hand to say enough, to understand the look of pain on your face if you accidentally get wet with hot soup, and to stop stirring when told. The research aims to develop the rules we need to introduce this level of cleverness into service robots who are working closely with people. "Professor Melhuish, of the BRL, said robots working in factories at present are kept behind gates for safety reasons--a measure that is not practical in the kitchen.The research is a joint effort between robotic engineers and scientists from West of England and Bristol universities. How are service robots at home different from those in factories？（）

The Northern Pike is a very bad fish. It is a big, hungry fish, and eats little fish. Many Northern Pike live in Lake Davis. They are killing all the smaller fish in the lake. The Northern Pike area serious danger to the lake because they eat all the smaller fish. Soon, all other kinds of fish in the lake will be killed off. This is not healthy for the environment (环境).Researchers are afraid that the Northern Pike will swim out of Lake Davis through many smaller rivers that feed into the lake. They could spread all over the country and damage many other water environments. If that happens, it would be too late to stop the Northern Pike.For ten years, officials have been trying to remove the Northern Pike from Lake Davis. They have tried using nets and poisons (毒). However, the Northern Pike population is still doing well in Lake Davis. Many people do not like the idea of using poison to kill the fish. They worry that the poisons are bad for humans who use the water. However, people haven’t found any poisons at all in local (当地的) wells.Scientists are going to try the poison again. This time, they will dry off the lake before putting the poison in. A public hearing will be held to talk about the problem. What could happen if the Northern Pike swim out of Lake Davis ？（）
He saw the old lady and her car on the side of the road. He could see she needed help. So he pulled up in front of her car and got out.Even with the smile on his face, she was worried. He didn’t look safe. He looked poor and hungry.He said, "I’m here to help you, ma’am. My name is Bryan Anderson. "All she had was a flat tire (瘪胎), but for an old lady, that was bad enough. Bryan changed the tire and she couldn’t thank him enough for the help. Then, the lady asked how much she owed him. She had already imagined all the terrible things that could have happened. He told her that if she really wanted to pay him back, the next time she saw someone who needed help, she could give that person the help they needed.A few miles down the road, the lady saw a small cafe She went in. The waitress came over with a sweet smile, one that even being on her feet for the whole day couldn’t erase. She noticed the waitress was nearly eight months pregnant (怀孕) , but she never let her aches be noticed. The old lady wondered how someone who had so little could be so giving to a stranger. Then, she remembered Bryan.After her meal, the lady paid with a one hundred dollar bill. The waitress quickly went to get change, but when she came back, she noticed something written on the napkin (餐巾纸) with the words saying: "You don’t owe me anything. Somebody once helped me out, the way I’m helping you. If you really want to pay me back, here is what you do : Do not let this chain of love end with you. "Under the napkin were four more $100 bills.That night when the waitress got home, she was thinking about what the lady had written. How could the lady have known how much she and her husband needed the money with the baby due next month As she lay sleeping next to her husband, she whispered soft and low, "Everything’s going to be all right. I love you, Bryan Anderson. \ What did the lady suggest if the waitress wanted to pay her back ？（）
