This is a rather strange story but it is quite true. In December 1996, a burglar broke into a golf club in a small town. When the police arrived to look into it, they found an unusual clue--- a piece of cheese with a bite-mark in it. The burglar had gone into the kitchen, and had eaten some food there. Then he had stolen some cigarettes and a little money. The police man in charge of the case guessed that the burglar was a local man. He thought that professional thieves would not bother to break into a golf club.He made enquires in the town and asked three suspects to come to the police station. When he questioned them about the burglary, they all denied stealing in the club.The policeman then gave each man a piece of cheese and asked them to bite it. He took the pieces of the cheese to a dentist and asked him to compare the bite-marks with that in the piece of cheese at the scene of the burglary. The policeman set free two of the suspects and questioned the third one. At first the man said that he was innocent . The policeman knew that the man was lying, so he encouraged him to talk until he began to contradict himself . The policeman told him about the bite-marks and the man had to admit his stealing. What can be the best title for this story? A) Bite-marks B) Regretful burglar C) Brave event D) Professional burglar

We have a real crisis in this country in the basic understanding of science. It affects our global competitiveness as a country, our national security, and the effectiveness of our social system. The misunderstanding about science is blinding our eyes. We know that an awful lot of teachers who are teaching science today have not been properly empowered to do so. School frequently isn't testing whether you understand something but whether you're familiar with it. What's Newton's second law? You say F=ma, and you get an A. That does not reflect a deep understanding of Newtonian mechanics. Science education is not just a body of facts; it's a process. To present it with appeal and excitement you need to picture it as a detective story--asking questions, making observations, and collecting evidence. You test and you fail but, you know, failure can lead to discovery. Another challenge we face is that science is often viewed as too hard, for experts only. But I don't actually think it's that difficult. People see science every day. They look outside and see weather and nature. They push a button in their house and the lights go on. Everybody's dealing with science every day. They just don't call it that. And it's important they do. In fact, science is determining the quality and outcomes of their life. Science needs creativity. And one of the best ways to be creative is to think "out of the box". However, we need more courage when we come to practice. Take me for example. Very early in my teens I decided to educate myself. I realized I would never be a very good student because I didn't like teachers judging me by what I thought were arbitrary standards. I decided I'd let the world judge me by whether I could do something of value--solve a problem or build something. That's why I quit school early and risked everything to start a company. I risked everything I had because I had nothing to lose. I'd rather fail at trying to do something really big than succeed at being medium. "When's the right age to think... The author takes his own example to say _ . A) school education may do little good to students B) teachers sometimes judge their students unfairly C) people need to take an unusual path to be creative D) failure at a big thing is better than a small success

Q: New findings suggest that brainy card games such as contract bridge may temporarily raise production of a key blood cell including in fighting off illness. After 90 minutes of play, bridge players had increased level of immune cell, according to research reported last week. A researcher, Diamond, studies bridge players from a woman's bridge club. She chose bridge players because the game includes skills stimulating a part of the brain called the dorsolateral cortex. Earlier animal research suggests that this part of the brain may play a role in the immune system. The findings are based on blood samples drawn from 12 women players. Their blood samples showed a rise in levels of white blood cells called T cells after they played bridge for 90 minutes. T cells are produced by the thymus gland and used by the immune system against diseases. The T cells count jumped significantly in eight of the bridge players, and slightly in the other four. The findings contribute to the field of neuroimmunology , whose name reflects the fact that the nervous system and the immune system are not considered separate and isolated systems. What isn't clear is whether the help to the immune system from an activity like contract bridge is lasting or temporary. It's also not clear whether the increase in T cells could finally be targeted against special illness. A T cell is _ . A) a brain cell B) a white blood cell C) a red blood cell D) a kind of dangerous blood

Wearing seat belt is,of course,the first step to safe driving.These additional measures might also save your life. Count to three.Keeping up enough space between your car and others is extreme1y necessary.Jim Clark,a California driving instructor,suggests a least amount of three seconds'following distance.To figure this,pick an object on the roadside ahead.When the car in front of you passes it,start counting one-thousand-one,one-thousand-two,one-thousand-three.If you get to that object before you reach one-thousand-three,you don't have three seconds of following time --- time needed to keep away from accidents. Let followers pass."If someone's driving after you,get out of his way,"Clark advises."You're better of being safe than right." Expect the worst.In a study,the Federal Highway Administration found that 68 percent of drivers do not come to a complete stop at stop signs.When you're driving and see someone come near to a stop sing,assume the person's not going to stop. And when you stop at a crossing and another car comes near with its turn signal on,don't take it true that the driver will turn.Instead,wait until he turns.He may have had the signal on for miles. Stay outside.In crowd,multilane traffic,drive in either the outside--left or outside--right lane."That allows you somewhere to go if a problem develops,"traffic expert Francis Kenel says."If you're in the middle,all you can do is to pause from time to time." Mr.Kenel tells us while driving in multilane traffic _ . A) we'd better find somewhere to go B) it will be better for us to drive in the outside lanes C) it is safer to drive in the middle D) we must drive on the left
