问题     Bernard Jackson is a free man today, but he has many bitter memories. Jackson spent five, years in prison after a jury wrongly convicted him of raping two women. At Jackson’s trial, although two witnesses testified that Jackson was with them in another location at the times of the crimes, he was convicted anyway. Why? The jury believed the testimony of the two victims, who positively identified Jackson as the man who had attacked them. The court eventually freed Jackson after the police found the man who had really committed the crimes. Jackson was similar in appearance to the guilty man. The two women had made a mistake in identity. As a result, Jackson has lost five years of his life.
    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 line-up of people. They can become confused by seeing many photographs or similar faces. The number of people in the line-up, and whether it is a live line-up or a photograph, may also affect a witness’s decision. People sometimes have difficulty 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 witness’s 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.  [br] What is the main idea of the passage?
选项 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.
答案 B
解析 这是一道篇章理解题。在做对文章主旨提问的题目时，可先做完以下几题，读完全文后再回头应对这样的题目。根据文中第六段最后两句"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．”(在有些案件中，证人的证词曾令无辜者蒙冤。但更多时候，它将众多的犯罪分子绳之以法。因此，证人的证词对于美国法律系统仍然意义重大。)可见，选项B“Eyewitness testimony，although sometimes incorrect，is valuable．”(尽管证人的证词并非总是正确，却仍然很有价值。)符合题意。故选B。
