During his stage life, he combined the traditions of the past with his own creations, shaping a style o f his own and giving birth to “The Mei Lanfang School”. He was also the first artist to introduce Peking Opera to an overseas audience, making it popular to the world.Mei Lanfang began his stage life at the age of 8. His teacher said he showed little hope because of his boring eyes. To improve this, he exercised them day after day. Thanks to his efforts, he managed to change his dull eyes into a pair of bright and expressive eyes and win national fame before the age of 20.In over 50 years on the stage, Mei Lanfang played no less than 100 different characters in the performance. He also wrote many new plays, designing the dances himself. The many dances he created form part of the g reat treasure that he left to Peking Opera.In 1930, Mei Lanfang started on a successful US tour. There his brilliant performances impressed the audience, making them realize that Peking Opera was a theatrical form of great value.56.Mei Lanfang was the first artist to introduce Peking Opera to ________.A.

Mei Lanfang’s great contributions to Peking Opera.BThe deserts of the world are not all covered with sand. Many of them have surfaces of rock or clay or small stones. They are not flat, either. They often have high hills and deep valleys. There is some plants’ life in many parts of the desert. Th ere is little rain in the desert, but it does fall often enough for most plants.The deserts of the world are not uninhabited(not lived by people). People also live outside oases(绿洲), but these people are not farmers. They have camels, goats, donkeys, sheep, etc. These animals can live on the desert plants and do not need much water.The people of the desert have to move constantly from place to place, they must always look for grass or desert plants for their animals. They usually live in tents. When there is no more food for their animals, they fold up their tents, pat them on their camels and donkeys, and move to another place. In good years, when there is enough food for their animals, they trade their skins and their goats and camel hairs with the people of oases for wheat and fruit. But in bad years, when there is not enough food for their animals, the people of the desert would attack the oases people. But they are also hospitable, no man in the desert would ever refuse to give a stranger food and water.59. According to the passage, deserts are mostly made up of _______.A. clayB. rockC. stonesD. sand60. The underlined word “hospitable” has the meaning of be ing _______.A. braveB. cruelC. strangeD. kind61. In the desert _______.A. it rains in spring onlyB. there is some rain, but far from enoughC. it rains for a short time every monthD. the rainfall is just enough for the plants62.

From the passage we know that life _______.A. is hard in desertsB. is happy in desertsC. is impossible in desertsD. in deserts is much better nowCIndia has many festivais, with some celebrations that last for weeks. However, none of them come even close to Holi, India’s most colorful and fun festival. Celebrated on the day following the full moon, this year’s festival happens to be on March 19th.As with most Indian festivals, this one also has many different folk stories. Most of them center around the success of good over evil. The most popular one is about a king, who hates his son Prahlada for loving the creator of the Universe—Lord Vishnu. When every attempt to stop him fails, his sister, Holika believed to be immune(免疫的) to fire, joins in the effort by inviting the young boy to sit with her inside a huge fire. Helped by the power of Lord Vishnu, Prahlada escapes safely, while the evil Holika is burned to death. To remember this event, huge outdoor fires are lit in the night before Holi in order to clean the air of evil spirits and to celebrate the death of the evil.So what’s so great about this day? While there are some fun parades(游行) and folk songs and dance performances, the most fun of all is walking to the streets and splashing(泼洒) people with water guns and dry colors and even covering them with entire buckets of colored water. On this day, everybody is fair game, no matter how old or how young.At about midday, the splashing comes to an end and people living close to oceans or rivers usually take a bath in the water to clean themselves before going home to a delicious home-made big dinner and a well-deserved short sleep, following this full day of fun and activities.64. Why does the king dislike his son Prahlada?A. Because Prahlada doesn’t love him.B. Because Prahlada is rude to Holika.C. Because Prahlada loves Lord Vishnu.D. Because Prahlada concentrates on his own success.65. Prahlada gets out of danger __________.A. with the help of Lord VishnuB. because of his good luckC. by beating his aunt HolikaD. using his amazing talent66. The underlined phrase “fair game” in Paragraph 3 refers to a person who __________.A. fights against others fairlyB. enjoys splashing peopleC. plays a trick on othersD. is the aim of splashing water67. After the fun activities, people living close to oceans or rivers often take a bath because __________.A. they have got dirty with dry colors and colored waterB. going home with colored water means bad luckC. they believe clean water will bring good luckD. taking a bath shows their true love for Lord VishnuDBelow is adapted from an English dictionary.

At 13，my hopes of fame and fortune clouded all judgement and I begged my parents to let me go.We have never been rich，but they saw my enthusiasm and agreed.I imagined being signed by some famous model companies. For months，any boredom or disappointment I faced was pushed aside because I knew I would soon have the chance to be real model. I thought I would grace the covers of famous magazines!Of course，I wasn't signed，but what hurt the most was being told that if I grew to 5′9″(about 1.75 metres) I could be a success. I prayed for a growth spurt (冲刺) because I could not imagine giving up my dream. I made an appointment with a local modeling agency and the agent demanded $500 for classes. $500 for a photo shoot，and $300 for other expenses. My parents only agreed after hours and hours of my begging.The agency sent me out on a few auditions，but with every day I didn't receive a call，I grew more depressed. The_final_straw came in July after I had decided to focus on commercial modeling. There was an open call in New York City.We spent hours driving and another few hours waiting，only to be told that I was too short. I was devastated (极度不安的)．Years later，I realized that the trip to New York was good as it made me notice I didn't actually love modeling，just the idea of it. I wanted to be special and I was innocently determined to reach an impossible goal. The experience has made me stronger and that will help me in the future.72．What's the author's parents' attitude toward her dream?A．Encouraging. B．Worried. C．Doubtful. D．Enthusiastic.73．What was it that made the author end her attempt to become a model?A．Her parents were strongly against it.B．She realized that it was impossible for her.C．Even a local modeling agency turned her down.D．She realized that she didn't actually love the idea of modeling.74．The underlined phrase “The final straw” probably means ________.A．the last in a series of bad things that happen to make someone very upset，angry，etc...B．the final result that she was admitted by the model company.C．the final audition given by the agency.D．the decision that she made at last not to be a model any more.75．What did the author learn from her experience of struggling to be a model?A．Where there's a will there's way.B．Being a model is not that easy.C．We should have our own judgement and should not just follow others.D．We might set unpractical goals but the experience can help us grow.第Ⅱ卷主观题（共35分）第一节：单词拼写（共10小题；每小题1分，满分10分）76.
