There is very simple way of measuring the height of a water-tower, which we cannot measure by climbing. Suppose, for example, that we wish to find out the height of the water-tower, AB, in a factory. We first of all go to where the water-tower is standing and measure a distance of, say, 25 feet from it. Then we take a stick, and stand it in the ground at the spot we have just marked. Let us suppose the stick we are using is 4 feet in height. We now walk farther away from the water -tower in the same straight line as when we measured off the distance of 25 feet. We go from the water-tower until we come to point E, where with our head on the ground, we see the top of the stick and the top of the water-tower in the same height line---that is, the top of the stick just covers the highest part of the water-tower. Every schoolboy can work out the height of the water-tower now. Suppose that the line CE is five feet. We know that the stick is 4 feet high and the distance BE is 30 feet. Thus, 5 is to 4 as 30 is to AB. To measure a water-tower in this way,   _  . A) no tool is needed B) Besides a stick, tape-measure   or at least a ruler is necessary. C) we have to use nothing but a stick D) we have to prepare a set of expensive tools

(Question)
When it came to role models, Diana Ortiz said her mother, Marcia Dominguez, was the "hero". Ms. Dominguez came to the United States from Cuba in 1979. She went to college and got a job as a social worker --- all the while raising three children in America mostly on her own. "It was always school first," Diana said, "My mom had us in a straight line. If we got out of line, she corrected us. She was a perfect woman. She was beautiful, she had the education and she had everything --- but the illness took over. When I was 11, it frightened me to see how quickly my mother's health was ruined by cancer. A week before I turned 14, my mother died at age 50. I had tried to prepare myself, but on the first morning I woke up without my mother, the sense of loss was painful." Diana had not seen her father for five years, who refused to provide for her. Diana then entered the city's foster care system. She has spent about four years in foster homes. Despite Diana's hard teenage years, the values her mother had planted in her mind inspired her to go after higher education. Since August 2010, she has been a fulltime student majoring in law. A public organization offers her tuition but she has part-time jobs to help people like her and earn more life experience. Her goal is a job in the Federal Bureau of Investigation. For now, Diana works 20 hours a week as a cashier at Marshalls, earning $7.25 an hour. In November, she moved into her own public housing studio apartment on the Lower East Side. She pays $236 a month in rent. Although she is out of foster care, Diana has been speaking at workshops for foster youths. She emphasizes that nothing should get in the way of their success, not the trials of their lives or what they may have lost. "I tell the young who have the similar experience like me, 'Why are you going to let what happened to you affect you in the long run?' " Diana said. " 'Why are you going to sit there and feel sorry for yourself? You're wasting precious time.' It is a message my mother would approve of. My... Which of the following words can be used to describe Ms. Dominguez? A) Learned, independent and strict. B) Positive, simple and graceful. C) Hardworking, dependent and tough. D) Kind, determined and lonely.

Ques: Famous centenarians   still active in arts, science are in no mood to retire."Those who stand still, die," is one of Oliveira's favorite phrases.He knows from experience what it means, as the Portuguese film director has reached the age of 102 and is still active in his profession.Every year, Oliveira shoots a film and is currently working on his next project."You have to work, work, work in order to forget that death is not far away," he said.When asked about his age, Oliveira said with some humility: "It's down to mother nature.It gave to me what it took from others." Being both mentally and physically fit in old age is partly a matter of luck, but it also has something to do with character.Not every white-haired person is wise and social skills, openness and the ability to train the brain are essential for senior citizens. Along with the architect Oscar Niemeyer (103), Nobel laureate Montalcini (101) and director Kurt Maetzig (100), Oliveira is one of those people of whom it would be very wrong to think as members of a listless elderly generation. Another master in his profession is the architect Oscar Niemeyer.The 103-year-old Brazilian is best known for his futuristic-looking buildings in Brasilia, but he also speaks out on behalf of the poor."The role of the architect is to struggle for a better world where we can develop a form of architecture that serves everyone and not just a privileged few," said Niemeyer recently.He spends almost every day working in his office in Copacabana, and even when he falls ill he keeps working on ideas: After a gallbladder   operation he composed a samba tune   in the clinic. Another man who could sing a song about age is 107-year-old Heesters.The Dutch-born opera singer spent most of his life performing in Germany, where he still works.Recently Heesters said: "I want to be at least 108-years-old." He also plans to keep performing." _ " Heesters has not given up trying to add to his tally  of awards and is looking for a "good stage role". Italian scientist Rita...

Question: Dear editor, I am writing to ask what has happened to our young people.They are not as polite or hard-working as my generation(I will give you two examples. Last Friday, I got on the underground at 9:15 a.m. It was very crowded so there was no free seat.There were some boys sitting on the seats near me.I didn't know why they were not at school.They were talking and laughing loudly. It was difficult for me to read my newspaper with all the noise.At the next stop, a pregnant woman and her daughter got on with lots of shopping bags.I expected the boys to let them sit down.They saw the woman but they did nothing.I had to ask them to give the woman and her daughter seats.   They did so but gave me a rude look. Last Saturday, I had dinner with my friend's family.I was glad to see his children, who I hadn't seen for ten years.During the dinner, I started talking about world politics with the children.It soon became clear that they didn't know much about it.They couldn't tell me the name of the King of Spain or President of Italy.All they knew about was the Internet or which singers were the most beautiful.In my days, students knew the kings, the queens and the presidents of every country in Europe. I worry about the future of Germany.How could these young people become good workers and parents? They sit around McDonald's after school instead of going to the library like I did at their age.Maybe they have too much money.Perhaps some readers can give us some ideas about what to do with this "lost generation". Yours sincerely, Frantz Vogts. By saying "lost generation", Mr Vogts refers to   _  . A) the fact that he is angry with young people today B) the people at his age C) his worry about these young people D) today's young people
