Not many Londoners know it either, but Henri does and he is willing to show it to you. Henri used to sleep in parks until he met a charity that helps homeless people get back on their feet by becoming tour guides. Rather than show traditional London sights, "Unseen Tours" t _ Henri has been teaching tourists about the history and architecture of Shoreditch, where he slept on public benches for three years. When he felt separated from the society, contact with the volunteer network "The Sock Mob" gave Henri hope. "Not everyone just looked down on me," he said. The tours aren't the only actions trying to help those who have suffered a misfortune to stand tall again. An innovative college for homeless people in London, the first of its kind in the country, is attracting hundreds of students. The Recovery College, set up by St Mungo's charity, is providing courses designed to improve technical skills and life skills. According to Andy Williams, who helps to organize the college, the most popular courses have proved to be about raising self-confidence and developing self-pride. Steve, now in his 50s, told a reporter how much of a difference it makes to "have a bit of confidence". He had difficulty learning to read and had to leave school when he was 12. Because Steve's problem was not recognized at the time, he was "seen to be unable to read or write", and suffered with depression and alcohol addiction. He says the status of "student" is itself important for people who are used to being treated as outcasts Some charities aim not only to help the homeless become independent but also to make them popular. The Homeless World Cup started ten years ago. Today the tournament draws teams from 48 countries made up of players-men and women-who are, or have been, living in the streets. It gives them a chance to become football heroes. Question: How does the Recovery College help the homeless people? - By training them to be guides - By offering them different courses. - By keeping in contact with them. - By asking more students to help them.
By offering them different courses.

Read the following article and select the best answer. Article: Lucky is the man who has no "skeleton in his closet." When a man has done something in his life that he is ashamed of, that he wants to hide, he is said to have a "skeleton in his closet." Some people may have more than one skeleton. As we have noted many times, it is hard to find out how these expressions begin. Sometimes, we get some hard facts. But more often we have to depend on guesswork. And that is true of this phrase, which came from England. Before 1832, English law did not permit a doctor to cut open a dead human body for scientific examination, unless it was the corpse of an executed criminal. But when it became legal, more and more doctors demanded skeletons for a more scientific study of medicine. It was helping in the advance of modern medicine. The demand had become so strong that men began to rob tombs and sell skeletons to doctors at high prices. We are told that a doctor would usually buy just one skeleton for scientific study. It became very important in his work. But he had to keep it hidden because most people objected to keeping such a thing. As a rule, the doctor keep his skeleton in some dark corner where it could not be seen, or hide it in a closet. After a time, people began to suspect every doctor of hiding a skeleton in the closet. From this suspicion, the phrase"a skeleton in the closet"took on a broader, more general meaning: to describe anything that a man wanted to keep others from discovering. It could be proof of a criminal act, or something much less serious. Well, that is one theory. One writer, however, believes that the phrase might have come from something that really happened. It is his guess that a hidden closet in some old English country home may have turned up a real skeleton, clear proof of some old family shame or crime. Well, one man's guess is as good as another. But this sounds like a story by the great French novelist, Balzac. Balzac tells us of a man who suspected his wife of having a lover. The husband comes home by surprise. But she hears him and quickly...
