Beloved, Song of Solomon and others explored the way African-Americans search for freedom and identity in a countryobsessed (受困扰的〉with skin color. Morrison was nearly 40 when she published her first novel The Bluest Eye in 1970. The Nobel Prize committee described her writing as language itself, a language she wants to liberate from nice". Her novels discussed America's past, focusing on black history and the effects of slavery and racism. She culled her characters "the unfree at the heart of the democratic (民主的) experiment".In 1988, she won the Pulitzer Prize for her novel Beloved, the story of a mother who kills her baby daughter rather than permit her to be born into slavery. It became a best-seller and was later made into a film with Oprah Winfrey. Many Americans admired her as the country's greatest living writer, including former President Barack Obama.She was born in 1931. She attended Howard University, an all-black university in Washington, D. C. At Howard, she read African. British and American literature, including writers William Faulkner and Virginia Woolf. After a short marriage, she became a single mother of two sons and worked as a book editor in New York*Several publishers rejected her first book The Bluest Eye but it impressed The New York Times' book critic (评论家)John Leonard, who believed Morrison was an important new voice. He said her writing was "so charged with pain and wonder that the novel becomes poetry".Morrison enjoyed her literary fame and was proud of her Nobel Prize.24. What are Toni Morrison's books mainly about?A. Women's equality and rights.B. The development of America.C. The literature of America.D. American history and racism.25. Which of the following helped Toni Morrison receive the Pulitzer Prize?A. Beloved.B. Song of Solomon.C. The Bluest Eye.D. The New York Times.26. Why is former President Barack Obama mentioned?A. To show Barack Obama's support in literature.B. To prove Toni Morrison' greatness as a writer.C. To stress Toni Morrison' contribution to America.D. To remind readers of the skin color of Barack Obama.27. What can we infer from John Leonard's words?A. He thought highly of Morrison.B. He rejected the book The Bluest Eye.C. The book The Bluest Eye made him painful.D. Toni Morrison's book was hard to understand.CConflict is part of everyday life. It is not always a bad thing --- it can lead to good discussions and improvements in die relationship between two people. However, if it's not handled properly, it can be destructive and can bother your studies or other areas of your life.We all have different styles of approaching conflict. Some of us avoid, others compete, give in. adjust or cooperate. Each of these styles has its strengths and weaknesses. So it’s important to know how youapproach conflict. Remember that blaming others and refusing to take responsibility for your role in a conflict can only worsen the conflict and lead to more anger, frustration (挫折),or fear. On the other hand, making the effort to listen without judgement, trying to understand the other party's needs, and searching for solutions in which everyone wins lead to healthy conflict resolution and may result in positive change. If you find that you can't work it out with the other person, you may want to seek the help of a neutral party, to help you work through the conflict.Whether you use the services of a third-party mediator or negotiate a solution between yourselves, the following principles are important to constructive conflict resolution: address the conflict before it becomes much more complex; separate the person from the problem; focus on interests rather than sticking to your position; commit to finding a mutually (相互地)beneficial outcome; avoid blaming others; listen actively; keep the lines of communication open; focus on the future.Be aware of the possibility that you may just have to agree to disagree. Not all conflicts can be resolved. For most people, values are negotiable and they are not always in line with the values of others. In a diverse community like we have now, we must accept and be respectful of difference.28. What would be the best title for the passage?A. How to Resolve Conflict.B. Different Ways for Conflict.C. Conflict Might Be a Good Thing,D. Not All Conflicts Can Be Resolved.29. What does the underlined part "a neutral party” in the second paragraph refer to?A. Supports that can back someone up all the time.B. People not supporting either side in a disagreement.C. A group of people who have the opinions in common.D. Judges that uphold justice when dealing with conflict.30. The second paragraph is mainly developed by ____________ .A. making comparisonB. giving examplesC. listing figuresD. explaining facts31. Which does the author agree with according to the passage?A. Conflict can lead to your worsening health if you disregard it.B. Conflict can result in improved relationship if dealt with properly.C. Conflict can develop better if you blame the other part of the conflict.D. Conflict can help you if you compete with the other part of the conflict.DNatural disasters take many different forms and can happen without warning. Earthquakes, floods, volcanoes, droughts, typhoons, and hurricanes are all natural disasters.The earthquake of 26 December 2004 resulted in one of the worst natural disasters in living memory. It was a massive underwater quake and occurred in the Indian Ocean. This caused a huge tsunami (海啸)to cross the Indian Ocean. It destroyed coastlines and communities and brought death and destruction to many people. The survivors needed fresh water, food and shelter as well as medical help. People from all over the world gave money.The surface of the Earth has not always looked as it does today; it is moving continuously (although very slowly) and has done so for billions of years. This is one cause of earthquakes、 when one section of the Earth crashes with another. Scientists can predict where this might happen and the area between plates is called a fault line. However, earthquakes do not always happen on Fault lines, which is why they are so dangerous and unpredictable.All the disasters are very dangerous and continue to kill thousands of people each year, but they are nowhere near the most dangerous disaster to ever happen on earth. One type of event in the earth's history has regularly killed millions of beings: asteroid (小行星)impacts (撞击). About once every million years the Earth is hit by a piece of rock and ice from space large enough to cause massive destruction (including earthquakes, volcanoes and ice ages) and sometimes to kill entire species. Sixty-five million years ago more than half the earth's species were killed by such a disaster, including all the dinosaurs(恐龙). Disasters on the Earth may seem dangerous, but the biggest threat to humans is likely to come from space.32. What did the world do when the tsunami occurred in the Indian Ocean?A. They gave away money to the beggars.B. They sponsored to help the people survive.C. They donated their possessions to the survivors.D. They helped rebuild the coastlines and communities.33. What can scientists predict about earthquakes?A. The possible time.B. The possible climate.C. The possible place.D. The possible frequence.34. Which is the best heading that matches Paragraph 3?A. What do earthquakes destroy?B. Why do earthquakes happen?C. How can we prevent earthquakes?D. Which is the most dangerous natural disaster?35. Where does the author think the most dangerous natural disaster will come from?A. Space.B. Earth.C. Humans.D. Wild animals.第二节(共5小题;每小题2分,满分10分)根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。
