(x﹣5)(x﹣11)=0,
所以x1=5,x2=11,
又因为三角形的两边长分别是4和7,所以第三边为5.
故答案为5.
【点评】本题考查了解一元二次方程﹣因式分解法:先把方程的右边化为0,再把左边通过因式分解化为两个一次因式的积的形式,那么这两个因式的值就都有可能为0,这就能得到两个一元一次方程的解,这样也就把原方程进行了降次,把解一元二次方程转化为解一元一次方程的问题了(数学转化思想).也考查了三角形三边的关系.
12.要组织一次排球邀请赛,参赛的每两个队之间都要比赛一场.根据场地和时间等条件,赛程计划安排7天,每天安排4场比赛,设比赛组织者应邀请x个队参赛,则x满足的关系式为 x(x﹣1)=4×7.
【考点】由实际问题抽象出一元二次方程.
【分析】关系式为:球队总数×每支球队需赛的场数÷2=4×7,把相关数值代入即可.
【解答】解:每支球队都需要与其他球队赛(x﹣1)场,但2队之间只有1场比赛,
所以可列方程为: x(x﹣1)=4×7.
故答案为: x(x﹣1)=4×7.
【点评】本题考查了由实际问题抽象出一元二次方程,解决本题的关键是得到比赛总场数的等量关系,注意2队之间的比赛只有1场,最后的总场数应除以2.
13.抛物线y=2x2﹣5x+1与x轴的公共点的个数是两个.
【考点】抛物线与x轴的交点.
【分析】抛物线与x的交点个数,即为抛物线y=2x2﹣5x+1与x轴的公共点的个数,因此只要算出b2﹣4ac的值就可以判断出与x轴的交点个数.
【解答】解:∵y=2x2﹣5x+1,
∴b2﹣4ac=(﹣5)2﹣4×2×1=17>0.
∴抛物线y=2x2﹣5x+1与x轴有两个交点.
即:抛物线y=2x2﹣5x+1与x轴的公共点的个数是两个.
故答案为:两个.
【点评】本题考查二次函数与x轴的交点问题,关键是算出二次函数中b2﹣4ac的值.
14.二次函数y=x2﹣2x的图象上有A(x1,y1)、B(x2,y2)两点,若1
【考点】二次函数图象与几何变换.
【分析】先根据函数解析式确定出对称轴为直线x=1,再根据二次函数的增减性,x<1时,y随x的增大而减小解答.
【解答】解:∵y=x2﹣2x=(x﹣1)2﹣1,
∴二次函数图象的对称轴为直线x=1,
∵1
∴y1
故答案为:y1

Now, researchers have concluded that “The Look of Love” is, indeed, all in the eyes: looking directly at someone makes you more attractive(有魅力的)to him/her. “Here, we show that gaze direction can also be important,” the researchers said. “Faces that were looking directly at the viewer were considered to be more attractive than faces with a turned-away gaze. This shows that people prefer faces that seem to like them and that attraction is not simply about physical beauty,” the researchers said at an important meeting. 26. Why did the writer mention the song written by Burt Bacharach? A. To tell us how popular the song is now. B. To prove that a good song lasts forever. C. To prove that the new finding is true. D. To lead to the topic of the passage. 27. According to the passage, what did researchers conclude? A. We can find a lot of things by looking at others. B. People usually show their love by looking at others. C. People usually look into other’s eyes to see if they love them. D. Looking directly at others makes you more attractive to them. 28. Conway and his fellow researchers may NOT have carefully studied the influence of on attractiveness. A. characters B. gaze direction C. facial expressions D. body language 29. We infer from the last paragraph the researches would probably disagree that . A. gaze direction can influence attraction B. people prefer faces that seem to like them C. physical beauty is only part of attraction D. a man makes himself more attractive by turning his gaze away 30. What is the best title for the passage? A. Smiling makes you more attractive B. Happy faces are more attractive C. An old song leads to a new finding D. The look of love really is in your We do some strange things when we don’t like the way our life is going. Too often we blame(责怪)someone else. “I wish my parents were more understanding.” “I have such a bad chemistry teacher!” “My friends are so boring and self-centered. They make my life worse and worse.” Blame! Blame! Blame! It seems natural to sing this self-pitying song, but the truth is, if you don’t like your life, you should do something about it. No one else knows exactly how you feel or what you need. No one can read your mind correctly. You are the only one with the power to decide how you feel about yourself. Choose how you want to think and act. Other people can’t make you unhappy or angry. They only act in their own way and then it’s up to you to decide how you will respond(回应). For example, your friends go out to lunch without you and you feel very angry. How are you going to act? You may blame your friends, “They are not kind. Who needs them anyway?” Or you may tell your friends how you feel, listen to their explanation, and let them know you’d like to be invited next time. When you decide everything in your own way, you’re getting hold of your own life and shaping(塑造)it according to your tastes and feelings. You can choose to be happy, to make friends and to build an interesting life. When you blame others for what is or isn’t happening in your life, you have stopped growing or learning. One of the most important rule is that you can never change another person by your direct action. The only person you have the right to change is yourself. Once you change, the other person has something different to respond to and change is possible. If you want change in your life, begin with yourself. 31. What should we do if we don’t like our life? A. Change what we’re doing. B. Read our minds correctly. C. Sing that self-pitying song D. Tell others what we want. 32. If the writer’s friends have dinner together without him, he may . A. ask somebody else to talk to hem B. do the same thing to them in return C. talk to them and try to find out why D. forget it and be still friendly with them 33. What’s the writer’s idea about how to change others? A. He thinks it’s impossible to change others. B. He believes our love can change everything. C. He chooses to talk with others directly. D. He prefers to change ourselves first instead. 34. At the beginning of the passage three examples are given . A. to support the idea that people often blame others B. to suggest that there are various problems in people’s life C. to show that not all chemistry teachers are fit for their job D. to explain the reason why some people’s life is worse and worse 35. What’s the best title for the passage? A. Blame! Blame! Blame! B. Who Controls My Life? C. Change makes you happy D. What Makes Me Unhappy?C This is no doubt that music plays a powerful role in our lives. It can calm our tired nerves after a busy day of work. Music even has the power to move us to tears when it stirs(激起)an emotional reaction. How then, does music play a role in special education? If music has the ability to touch those hidden places we all carry inside, it proves an important tool for the special education teacher. For students with emotional problems, music can help soothe(抚慰)sadness. Consider the child that arrives in class depressed and upset. If music can indeed relax and calm him, he is more likely to focus and participate in class. Dr. R. Joseph, author of Behavioral Neurology, writes, “It is well recorded that patients with left hemisphere(大脑半球)damage, who may be unable to speak or recognize words, can sing a melody(曲调).” For this reason, some special education teachers have found it helpful to set their lessons to music. When students cannot understand or remember certain things, singing them helps make it easier. Nature magazine reported “Music training helps underachievers. In Rhode Island, researchers studied eight public school first grade classes. Half of the classes became ‘text-arts’ groups, receiving ongoing music training.

The role of music in special educationD When Sir Winston Churchill. the great British prime minister, reached his eightieth birthday in November 1954, he was presented with his portrait by a well-known modern artist, Grantham Sutherland. The painting had been ordered and paid by the members of Parliament(国会), who wanted to honor the Grand Man of World war Ⅱ. Sir Winston and Lady Churchill were deeply moved by this mark of respect and affection. Neither of them, of course, allowed the donors(捐赠者)to see how much they both disliked the portrait. “It makes me look stupid—which I am not!” Churchill protested in private. Publicly, he only said that it was “a fine example of modern art.” His friends smiled: it was well-known that Sir Winston didn’t care for modern art. Churchill was so unhappy about the portrait that finally his wife had it destroyed. Churchill died at ninety in January 1965. Lady Churchill followed him in 1977. Shortly after her death, the public learned what had happened to Sutherland’s painting, and a heated argument broke out. The painter was understandably sad. The artistic community, shocked and angry, claimed that the destruction of the picture had been a crime. Historians said that they regretted the disappearance of a historical document. All agreed that Churchill didn’t have the right to do what they had done. Well--did they? A good part of the public felt that the owner of a portrait had the right to get rid of it if it made him so unhappy. The question, however, has been raised many times before: who has the right to a work of art—the sitter, the owner, the donor or the artist who created it? And when the painting is the portrait of a historical figure, should the right of posterity(后代)be considered, as the historians claimed? 41. To have Churchill’s portrait painted was the idea of .
