The police said it involved a hit-and-run driver. The car was dark and was last seen traveling east on Ashton Avenue from Veteran Avenue. The investigation is ongoing. It appears that the driver struck and seriously injured the pedestrian, and left the victim lying in the roadway without even stopping to help or call emergency personnel. Outrageous! Leaving the scene of an injury or fatal crash is a serious crime under California law. California Vehicle Code 20001 (a) states: “The driver of a vehicle involved in an accident resulting in injury to a person, other than himself or herself, or in the death of a person shall immediately stop the vehicle at the scene of the accident.” We hope the driver in this case is arrested and brought to justice. If you have any information about the suspect or the vehicle, please visit the Hit-and-Run Reward website at to offer a useful tip and become qualified for a $1,000 reward. 操作提示:正确选T,错误选F。1.

F解析:1. 这是一道细节题。第一段第一句“A pedestrian was critically injured…”表明在这起事故里当事人只是严重受伤,并非死亡,所以为F。2. 这是一道细节题。第三段的第三句“Leaving the scene of an injury or fatal crash is a serious crime under California law.”说明这是一种犯罪,所以为F。3. 这是一道细节题。跟第二段的最后一句“The investigation is ongoing.”意思一样,所以为T。4. 这是一道细节题。第三段的最后一句提到根据California Vehicle Code 20001 规定,任何司机造成其他人员受伤的,应当立即停车,可是文章中的司机却逃走了,所以是违反了此规定,所以为T。5. 这是一道细节题。第四段最后一句表明提供的线索有用,才有可能得到奖赏,并非所有的线索都能得到一千美元的奖赏,所以为F。人文英语2
