听力原文： Michael Dell, the 39-year-old chairman and founder of Dell Computer, was at the top of the annual list of the "40 Richest Americans under the Age 40". His first business idea was to take apart an Apple computer in the bedroom of his parents' Houston, Texas home. From there, he went on selling computers out of his dorm room. He had developed a brand new approach to do business: sell computers directly to the consumers without going through retailers. And, in the process, he decided to design and deliver a computer based upon the customers' special needs. Prior to this there was absolutely no idea about make the PC special for each customer. In 1984, he founded the Dell Computer Corporation with US $1,000. Dell gave a short version of his success secrets at a conference in Texas. He said:" First of all, don't start a business just because everybody else is doing it or it looks like it's a way to make a lot of money. Start a business because you found something you really love doing and have a passion for. Start a business because you found something unique that you can do better than anyone else. And start a business because you really want to make a big contribution to society over a long period of time." (33) A．Between the age of 20 to 30. B．Between the age of 30 to 40.

The two women in this case were eyewitnesses. They clearly saw the man who attacked them, yet they mistakenly identified an innocent person. Similar incidents have occurred before. Eyewitnesses to other crimes have identified the wrong person in a police lineup or in photographs. Many factors influence the accuracy of eyewitness testimony. For instance, witnesses sometimes see photographs of several suspects before they try to identify the person they saw in a lineup of people. They can become confused by seeing many photographs or similar faces. The number of people in the lineup, and whether it is a live lineup or a photograph, may also affect a witnesses decision. People sometimes have difficulty in identifying people of other races. The questions the police ask witnesses also have an effect on them. Are some witnesses more reliable than others？ Many people believe that police officers are more reliable than ordinary people. Psychologists decided to test this idea, and they discovered that it is not true. Two psychologists showed a film of crimes to both police officers and civilians. The psychologists found no difference between the police and the civilians in correctly remembering the details of the crimes. Despite all the possibilities for inaccuracy, courts cannot exclude eyewitness testimony from a trial. American courts depend almost completely on eyewitness testimony to resolve court cases. Sometimes it is the only evidence to a crime, such as rape. Furthermore, eyewitness testimony is often correct. Although people do sometimes make mistakes, many times they really do identify individuals correctly. American courts depend on the ability of the 12 jurors, and not the judges, to determine the accuracy of the witnesses testimony. It is their responsibility to decide if a certain witness could actually see, hear, and remember what occurred. In a few cases, the testimony of eyewitnesses has convicted innocent people. More importantly, it has rightly convicted a larger number of guilty people; consequently, it continues to be of great value in the American judicial system. What is the main idea of the passage？ A．Bernard Jackson spent five years in prison for no crime of his own. B．Eyewitness testimony, although sometimes incorrect, is valuable. C．Police officers are no better eyewitnesses than civilians are. D．American courts rightly convict a larger number of guilty people.

A．A.lain B．B.lay C．C.lying
