July 16th was a bad day for Mr. Arthur Johnson. In the morning, he set off from his home in Santa Barbara, California. It was the start of his summer holidays and he decided to visit friends at Las Vegas,then he hoped to go fishing in Lake Mead, 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 drained (耗尽)the battery 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 (燃料泵).
