Прочитай текст и выполни задания после него.
Tony Redford was a journalist. He wrote articles for a magazine called Business News. He was a young man, of medium height. He had rather long, dark brown hair and a small moustache. There was always a very serious look on his face. He looked even more serious that morning. He was in his boss's office. His boss was called Liz Davis and she was the editor of Business News.
«Well, Tony. Your first article about the electronics industry is going to the printer's this afternoon. It's very interesting. But what about your second article? Are you sure you can write two articles about the electronics industry? I mean, isn't one enough? » she asked. «Listen, Liz, I tell you that the second article is going to be more interesting than the first! Far more interesting! »
«I am going to get some information this evening about a small company called Shandor Electronics. The director is probably one of the best electronics engineers in the world. But nobody knows very much about him. Not even where he comes from. He lives on a yacht. He never visits his factory in Southampton. Someone goes to the yacht from the factory every morning in a helicopter. Now... I know an engineer who works at that factory. His name is Presley, and Presley tells me that Shandor has plans for a new kind of electronic brain. It's much smaller but far better than any other electronic brains on the market today. I'm going to meet Presley in Southampton this evening. I am going to use the information I get from him in my second article. Presley says Shandor is going to make some new kind of robot, too. But he doesn't know very much about that. It's one of the company's biggest secrets! »
