In this section, there is one passage followed by a summary. Read the passage carefully and complete the summery below by choosing a maximum of three words from the passage to fill in each of the blanks 51-5.Remember to write the answers on the answer sheet.　　For many years after he formed his Theory of Relativity, Albert Einstein visited many universities in different cities where he gave talks about it. He had his own chauffeur who drove him to where he was to give the talk. The chauffeur sat at the back of the room while he was giving his lecture, and then drove him home.　　One day, the chauffeur said to Einstein, “Professor, I have heard you give your talk so many times that I know every word of it.” “Do you?” Einstein said with a smile. “Let’s find out, shall we? You give my next talk for me. Nobody knows what I look like where we’re going. I’m just a name to them.” Just before they reached the university where Einstein was to give his talk, he changed places with his chauffeur.　　The chauffeur’s memory was excellent and he was able to give Einstein’s talk exactly as Einstein gave it. He did not understand a word he was saying, but this did not seem to matter. Then, as he was leaving the university, one of the teachers who had been at the talk came up to him.　　“Professor Einstein,” he said. “That was a most interesting talk. I’d be grateful if you would answer a question.” The chauffeur hurried on. “I’m sorry,” he said, “but I’m late for my next meeting.”　　“I’ll walk with you,” the teacher said. “I want to talk to you about the problem.” The teacher walked along beside the chauffeur and asked him to solve a very difficult mathematical problem.　　The poor chauffeur couldn’t understand the problem, let alone attempt an answer. He did not know what to say. Then he had an idea. “It’s so simple,” he said. “Even my chauffeur could answer it.”　　He pointed to his car, where Einstein was standing, still wearing the chauffeur’s cap.　　“This man has a maths question,” he said to Einstein. “It’s so easy I’m sure even you can answer it.”　　Summary:　　Albert Einstein was a famous scientist who worked out the Theory of Relativity. He used to travel around the country with his chauffeur giving (1)      on mathematics. His chauffeur knew his talk very well so Einstein asked him to give the talk at the next (2)      where they did not know him.
