阅读理解。 July 16th was a bad day for Mr. Arthur Johnson. In the morning, he set out from his home in Santa Barbara, Califomia. It was the start of his summer holidays and he decided to visit Wends at Las Vegas, then he hoped to go fishing in Lake Mead, 40 km from Las Vegas. Johnson's troubles started while he was driving happily across the Mojave Desert. His car went wrong and he tried to repair it. Then, to make matters worse, his attempts to start the car used up the battery (电 池) and left it useless. After Johnson had waited an hour in the hot sun, a Canadian driver, John Williams, stopped and tried to help him. When both men failed, Williams promised to telephone a workshop to ask it to send a truck to pull the car away and repair its fuel pump. Johnson left the keys in his car and sat in the shade of a large tree. Soon he fell asleep. While he was sleeping, a repair truck arrived from San Pedro (the nearest town) and pulled his car away. Later on, Johnson woke up and thought that somebody had stolen his car. He started to walk back towards San Pedro but a police car stopped him to find out why he was walking in the desert. Johnson looked like a man wanted in Los Angels for robbery, so the police detained him at San Pedro for the night. The next day, Johnson telephoned his friends in Los Angeles. They drove to San Pedro and made the police believe that Johnson was a harmless salesman, so they set him free. 1. Johnson's car went wrong ____.
