第41题,In 1920, barely out of his teens, Alfred Hitchcock went to work for an American film company which had opened a studio in Islington, London. His first job at the studio was writing captions （脚本） for silent movies. Within two years, he was writing scripts（剧本） and working as an assistant director. For the rest of the 1920s, Hitchcock worked on one film after another in Britain and Germany. Filming was often a rough-and-ready（匆忙做成的） affair and the assistant director was required to step in and plug gaps. A cameraman went missing, Hitchcock became a cameraman. A scene needed rewriting, Hitchcock rewrote it. Someone needed to be in charge of money when the film crew was on location, Hitchcock looked after the money. At the same time, this being the era of silent movies, Hitchcock was learning the language of cinema: telling a story－not through dialogue, but through visual images（视觉镜像）. This led to his success later. When he began to direct his own films, first in Britain and later in Hollywood, he was determined to make films that held the audience\'s attention and kept tension（严重感）. He succeeded. Hitchcock\'s ability to put you on the edge of your seat makes him one of the greatest makers of suspense（悬念） movies. （以下为试题题干）He had taken up different jobs before he succeeded.
A、错误
B、正确
正确答案:
第42题,The workers who brought the girl to the orphanage knew little about her. The streets where they found her had been her home for many years. Her parents were unknown. They left her long ago. At the orphanage, the girl, like all the children there, was taught to read and write. While she was studying at the orphanage，she learned something else－to be independent. At twenty-one，she left the orphanage and began work as a secretary. And then, in 1975, while she was still working as an ordinary secretary, something special happened. She entered the Miss Hong Kong competition and won it. This was the turning point in her life. Now her name, Mary Cheung, was known to everybody. Mary entered the competition because she wanted to show that orphanage girls could be something. Winning the competition gave her the chance to start a new life. This led her first into television and then into business as a manager. When she was working as a manager, she had trouble with her reports. "My English just wasn\'t good enough." she says. Luckily, she had a boyfriend (who later became her husband) to help her. Mary studied management at Hong Kong Polytechnic and graduated in 1980. She started her own business in 1985. But she did not stop developing herself. She then studied at the University of Hong Kong. Since 1987，she had spent a lot of time on photography. She has held several exhibitions of her work in many places－China, New Zealand and Paris. She still found time, however, to work on TV, write for newspapers and bring up her family. The girl from the street has come a long way, but her journey is not finished yet. （以下为试题题干）Mary\'s boyfriend was good at English.

正确答案:
第44题,All over the world people enjoy sports. Sports help to keep people healthy, happy and help them to live longer.Sports change with the season. People play different games in winter and summer. Games and sports often grow out of people\'s work and everyday activities. The Arabs use horses or camels in much of their everyday life; they use them in their sports, too. Some sports are so interesting that people everywhere go in for them. Football, for example, has spread around the world. Swimming is popular in all countries near the sea or in those with many rivers. Some sports or games go back to thousands of years ago, like running or jumping. Chinese boxing, for example, has a very long history. But basketball and volleyball are rather new. Neither one is a hundred years old yet. People are inventing new sports or games all the time. People from different countries may not be able to understand each other, but after a game they often become good friends. Sports help to train a person\'s character. One learns to fight hard but fight fair, to win without pride and to lose with grace. (4)、From this passage we can see that according to the author sports and games are significant to our life in many respects.

第45题,In 1920, barely out of his teens, Alfred Hitchcock went to work for an American film company which had opened a studio in Islington, London. His first job at the studio was writing captions （脚本） for silent movies. Within two years, he was writing scripts（剧本） and working as an assistant director. For the rest of the 1920s, Hitchcock worked on one film after another in Britain and Germany. Filming was often a rough-and-ready（匆忙做成的） affair and the assistant director was required to step in and plug gaps. A cameraman went missing, Hitchcock became a cameraman. A scene needed rewriting, Hitchcock rewrote it. Someone needed to be in charge of money when the film crew was on location, Hitchcock looked after the money. At the same time, this being the era of silent movies, Hitchcock was learning the language of cinema: telling a story－not through dialogue, but through visual images（视觉镜像）. This led tohis success later. When he began to direct his own films, first in Britain and later in Hollywood, he was determined to make films that held the audience\'s attention and kept tension（严重感）. He succeeded. Hitchcock\'s ability to put you on the edge of your seat makes him one of the greatest makers of suspense（悬念） movies. (2)、According to the context, "step in and plug gaps" (in Line 3, Para. 2) means asking for one\'s help.
