二、阅读理解AIt seems that no one can live a happy life without friendship. While a great number of people expect others to be their friends, they don’t give friendship back. That is why some friendships don’t las t long. Tohave a friend, you must learn to be one. You must learn to treat your friend the way you want your friend to treat you. Learning to be a good friend means learning three rules: be honest; be generous; be understanding.Honesty is where a good friendship starts. Friends must be able to trust one another. If you do not tell the truth, people usually find out. If a friend finds out that you haven’t been honest, you may lose your friend’s trust. Good friends always depend on one another to speak and act honestly.Generosity means sharing and sharing makes a friendship grow. You do not have to give your lunch money or your clothes. Naturally you will want to share your ideas and feelings. These can be very valuable to a friend. They tell your friend what is important to you. By sharing them, you help your friend know better.Sooner or later everyone needs understanding and help with each other. Something may go wrong at school. Talking about the problem can make it easier to solve. Turning to a friend can be a first step in solving the problem. So to be a friend you must listen and understand. You must try to put yourself in your friend’s place so that you can understand the problem better.No two friendships are exactly alike. But all true friendships have three things in common. If you plan to keep your friends, you must practice honesty, generosity and understanding.11．Some friendships don’t last long because ________.A. there are too many people who want to make friendsB. those who give others friendship receive friendship from othersC. some people receive friendship but don’t give friendship backD. they don’t kno w friendship is something important12．According to the passage, honesty is ________.A. something impossibleB. more important than anything elseC. as important as moneyD. the base of friendship13．Which of the following isn’t talked about in the p assage?A. You should tell your friends the truth.B. A friend who gives you his lunch money is a true friend. ]C. Discussing your problems with your friends often helps to solve the problem.D. Sharing your mind with your friends is valuable.14．The best title of this passage is ________.A. Honesty Is the Best PolicyB. A Friend in Need Is a Friend indeedC. Three Important Points in LifeD. How to Be FriendsBDanielle Steel, America’s sweetheart, is one of the hardest working women in t he book business. Unlike other productive authors who write one book at a time, she can work on up to five. Her research before writing takes at least three years. Once she has fully studied her subjects, ready to dive into the book, she can spend twenty hours nonstop at her desk.Danielle Steel comes from New York and was sent to France for her education. After graduation, she worked in the public relations and advertising industries. Later she started a job as a writer which she was best fit for. Her achievements are unbelievable: 390 million copies of books in print, nearly fifty New York Times best-selling novels, and a series of “Max and Martha” picture books for children to help them deal with the real-life problems of death, new babies and new schools. Her 1998 book about the death of her work shot to the top of the New York Times best-selling list as soon as it came out. Twenty-eight of her books had been made into films. She is listed in the Guinness Book of World Records for one of her books being the Times best-seller for 381 weeks straight.Not satisfied with a big house, a loving family, and a view of the Golden GateBridge, Danielle Steel considers her readers to be the most important resource and has kept in touch with them by e-mail. While she is often compared to the heroines of her own invention, her life is undoubtedly much quieter. But, if she does have anything in common with them, it is her strength of will and her inimitable (独特的) style. There is only one Danielle Steel.15．Danielle Steel is different from other writers because ________.A. she can write several books at the same timeB. she often does some research before writing a bookC. she is one of the most popular American women writersD. she can keep writing for quite a long time without a break16．Children who have read “Max and Martha” picture books may know ________.A. how to deal with affairs at schoolB. what to do if Max and Martha dieC. what to do when new babies are born into their familiesD. how to solve the difficult problems in their writing classes17．One of Danielle Steel’s achievements is that ________.A. some TV plays were based on her booksB. her picture books attracted a lot of young menC. one of her books became a best-seller in 1998D. she wrote the Guinness Book of World Records18．We can learn from the passage that Danielle Steel ________.A. lives an exciting lifeB. values her readers a lotC. writes about quiet womenD. is pleased with her achievements三、完形填空阅读下面短文，掌握其大意，然后从第21—40 各题所给的四个选项（A、B、C 和D）中，选出最佳选项。
