It happened in a small village in Australia, where some dangerous animals live in the forest.‎ Lisa, a 33-year-old mother, went to cook lunch in the kitchen, her 3-year-old son, Barney, playing by himself in the garden.‎ Suddenly, a loud cry of Barney came into the mother’s ears. Lisa rushed into the garden in a hurry and found a big snake entwining（缠绕） the little boy with its body and trying to eat the boy. It was a boa（蟒）. Lisa was terrified and quite ‎ angry. She decided to save her son from the boa’s mouth.‎ It was great mother’s love that made Lisa forget what she was facing. She took up a hoe（锄） from the ground and beat（打）the boa as hard as she could.‎ One...two...with the hoe, Lisa beat the boa time and time again, but useless. The little boy’s voice and breath were getting weaker and weaker, Lisa’s heart was broken and she got nearly mad.‎ Suddenly Lisa put away the hoe and threw herself to the boa, opened her mouth and bit（咬） into the boa’s back. The boa was so badly hurt that it let go of Barney and moved into the forest hurriedly. It had never known how a woman had such sharp（锋利旳）teeth. Soon the boa was found dead in the forest.‎ It was great mother’s love that saved the little boy.‎ ‎（ ）48. When she came into the garden, Lisa found __________.‎ A. her son was in danger of losing his life B. her son was playing with a big snake C. a boa was playing with her son D.

In this passage the writer mainly wants to tell us __________.‎ A. the boy is too young to fight with the boa B. how sharp the woman's teeth are C. a boa is a dangerous animal D. how great mother’s love is ‎（C）‎ We often ask for information or help, especially when we visit a foreign country. So knowing how to ask for information politely is important. In English, “Where are the restrooms?” and “Could you please tell me where the restrooms are?” are correct English, but the first could sound rude. It’s important to use correct language, but sometimes we need to learn how to be polite.‎ In English, just like in Chinese, we change the way we speak when talking with different people. If you say to your teacher, “Where is my book?” This will sound rude. But if you say, “Excuse me, Mr West. Do you know where my book is?” Your question will sound much more polite. Of course it might be all right to say “Where is my book?” in some situations, perhaps with people you know well.‎ ‎“Peter, give me your pen. ”can sound rude in English. Usually in English, polite questions are longer such as “Could you please...?” or “Can I ask...?” It sounds more polite to say. “Peter, could you please give me your pen?” Sometimes we might even need to spend some time when you stop a stranger in the street. We might first say, “Excuse me. Can you help me?” or “I’m sorry to trouble you but. ”before asking them for help.‎ It might seem that speaking politely is more difficult than being direct（直接）. However, if you want to be a polite person, you should learn about language etiquette（规矩）. It is just as important as learning grammar or vocabulary. And doing this will also help you become better at English, or any other language you wish to speak.‎ ‎（ ）52. What is the polite way when you ask for help?‎ A. Pass me the watch, Li Tao.‎ B. Where is the supermarket?‎ C. Tell me where I can find a bank.‎ D. Could you please give me your pen?‎ ‎（ ）53. Why do we need to learn polite language? Because __________.‎ A. they can improve our grammar and vocabulary B. they can help us become better at English C. everyone wants to be polite D. the teachers tell us to do so ‎（ ）54. From the passage, we can infer（推测） the writer __________.‎ A. thinks being direct is nothing important B. knows much about spoken language C. is good at asking for directions D. often speaks many languages ‎（ ）55. What’s the main idea of the passage?‎ A. How to start a polite talking with strange people.‎ B. Correct language is as important as polite one.‎ C. How to use correct language is important.‎ D. People should learn to speak politely.‎ 七、阅读短文还原句子（共4分, 每小题1分）‎ 阅读短文, 根据短文内容, 从短文后旳五个选项中选出能填入空白处旳最佳选项.选项中有一个多余选项.‎ Jim, an 11-year-old boy, was playing with a ball.
