【简答题】
Old people are always saying that the young people are not【61】they were. The same comment is【62】from generation to generation and it is always【63】. It has never been truer than it is today. The young are better educated. They have a lot more money to spend and enjoy【64】freedom. They grow up more quickly and are not so【65】on their parents. Events which the older generation remember vividly are【66】more than past history. This is as it should be. Every new generation is【67】from the one that preceded it. Today the difference is very marked indeed. The old always assume that they know best for the simple【68】that they have been【69】a bit longer. They don't like to feel that their values are being questioned or threatened. And this is precisely what the【70】are doing. They are questioning the 【71】 of their eiders and disturbing their complacency. They take leave to 【72】 that the older generation has created the best of all possible words. What they reject more than 【73】 is conformity. Office, hours, for instance, are nothing more than enforced slavery. Wouldn't people work best if they were given complete freedom and 【74】 ? And what 【75】 the clothing? Who said that all the men in the world should 【76】 drab grey suits? If we turn our 【77】 to more serious matters, who said that human differences can best be solved through conventional politics or by violent means? Why have the older generation so often used 【78】 to solve their problems? Why are they are so unhappy and guilt-ridden in their personal lives, so obsessed with mean ambitions and the desire to amass more and more 【79】 possessions? Can anything be right with the rat-race? Haven't the old lost 【80】 with all that is important in life? (56)
