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, al though 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.
   Many factors influence the accuracy of eyewitness testimony. For instance, witnesses some times 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 of similar faces. The number of people in the lineup, and whether it is a live lineup 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.
   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 in dividuals correctly.
   American courts depend on the ability of the twelve 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.
From the text we know that______.
选项 A、eyewitness testimony plays an essential part in the U.S. court trial
B、police identification is more reliable than that of the ordinary people
C、crime victims often fail to give positive identification of the suspects
D、the jury relies more on the judge than on the eyewitness for a decision
答案A
解析 推断题。文章最后一段最后一句“...it continues to be of great value in the American judicial system．”目击证人的证词 在美国的法律系统中仍然有很大的价值，与A项“目击证人证词在美国案件审理中起着重要的作用”表示相同的意思，所以A正确。由第三段中的心理学家发现在正确记住罪犯的详细信息方面警察和普通人没有差别，可以看出B项“警察辨认比普 通人更加具有可靠性”是错误的。由文章第四段可以看出受害 者并不是经常辨别犯罪嫌疑人失败，而是在大多数情况下
