Life used to be fun for "teenagers". They used to have money to spend, and free time to while away (消磨). They used to wear teenage clothes, and meet in teenage coffee bars and discos. Some of them still do. But for many young people, life is harder now. 1. are difficult to find. There's not so much money around. Things are 2. , and it's hard to find a place to live in. Teachers say that students work harder than they used to. They are less 3. in politics, and more interested in 4. exams. They know that good exam results may bring them better jobs. Most young people worry more about money than their parents did twenty years ago. They try 5. less and save more. They want to be able to get homes of their own one day. For some, the answer to unemployment (失业) is to leave home and look for jobs in one of Britain's big 6. . Every day hundreds of young people arrive in London from other parts of Britain, looking for jobs. Some find jobs and stay. 7. don't, and go home again, or join the unemployed (失业者) in London.

Three quarters of them do more or less what their parents did. They do their best at school, find some kinds of jobs in the end, and get 9. in their early twenties. They get on well with their parents, and enjoy their family life. After all, if they don't, they 10. be British, will they? |
Adults usually do not remember most of the things that are taught by their teachers at school. But this story is one 16 that I will never forget. It was a normal Monday morning, and my teacher was teaching us about 17 things in life and about devoting ourselves to what we really need. This is how the story went: 18 lived in a certain part of London, and he would wake up every morning and go to the underground. He would get onto the train right to Central London, and then sit at the street corner and 19 . He would do this every single day of his life. He sat at 20 street corner and begged for almost 20 years. His 21 was dirty, and a stench （恶臭） came out. The neighbors could not bear the 22 any more, so they called for the police officers to clear the place. The officers knocked down the door and 23 the house. There were small bags of 24 all over the house that he had collected over the years. The police counted the money, and they soon 25 that the old man was a millionaire. They waited outside his house expecting to 26 the good news with him. When the old man arrived home that evening, one of the officers told him that there was no need for him to beg any more as he was a 27 man now, a millionaire. But the old man said 28 ;he went into his house and locked the door. The next morning he woke up 29 ,went to the underground, sat at the same street corner and continued to beg. Clearly, this old man had no great plans, 30 or anything significant (重大的) for his life. We learn nothing from this story but to stay focused on the things we enjoy doing.
