Then answer the questions and translate the underlined sentences into Chinese. Write your answers on the answer sheet.Much work has been directed towards examining teacher-student interactions, and a number of instruments have been designed to analyze the pattern of interaction in the classroom. However, less attention has been paid to the kind of discourse that student-student interaction produces. This oversight needs to be addressed, since most ELT coursebooks do not deal with speaking by breaking it down into micro-skills work. Instead, they often have the vague aim of ‘promoting learner fluency’. (54) This article argues that direct instruction strategies can be applied to help learners develop speaking skills, and in particular to become aware of patterns of interaction. What has been largely overlooked is that practicing conversation also entails knowing how to use language to interact. (55) ‘Students’ success in two-way communication does notjust depend on what they produce, but also on how effectively they are able to participate in conversational exchanges. We have come to recognize that conversation involves far more than knowledge of the language system and the factors creating coherence in one-way discourse; it involves the gaining, holding, and yielding of turns, the negotiation of meaning.51. What does oversight mean?__________________________________________.52. A common feature of coursebooks is that ___________________.53. Is the conversation closely related to the negotiation of meaning?__________________________________________.54-55. Translate these two sentences into Chinese.Part VIII. Writing (15 points)Some teachers hold that the primary skills to be developed are reading and writing. Thus little attention is given to speaking and listening, and almost none to pronunciation.

诗歌散文类】1. WatchingDear, father’s ship is very near,We’ll blow him kisses, baby dear.He may come home today.A happy wind that travels south Seems just to stop round my mouth, Then bear a kiss away.Come, baby, I will hold you so.We’ll watch the waves that outward go, And call, “Come back today!”For father’s heart seems always near, And who can tell but he may hear,Or know the words we say?We first will see a spot of white,Far, far away, where the lightwill bring the morning;So quiet will his coming look.It will be like waking from a dream,To wave our hands to him.He is not very far away,For mother said he’d come today—We knew it by her face;She caught you up and kissed you so,And now she’s busy to and fro,And sings about the place.【客观题】1) Why will the mother watch the waves and call, “Comeback today!”?2) What will happen when the mother sees a spot of white? 【主观题】1) Does your father often need to go out on business? If hedoes, what will you do when you miss him?2) What will you and your mother do to welcome yourfather home?2. The Champa FlowerIf I became a champa flower, just for fun,And grew high up of the treeAnd shook in the wind with laughterAnd danced on the green leaves,Would you know me, mother?You would call, “Baby, where are you?”And I should laugh to myself and keep quiet.I should shyly open my flowers and watch you at your work.When after your bath, with long hair over your shoulders, You walked pass the champa tree to the little yardWhere you say your wishes,you would find the smell of the flower,But you would not know that it came from me.After the lunch,You sat at the window reading,And the tree’s shadow jum ped over your hair and knees.I should let my shadow jump on the page of your book,Just where you were reading.But would you think that it was the small shadow of your child?When in the eveningYou went to feed the cows with lamp in your hand,I should jump onto the ground againAnd be your own baby once moreAnd beg you to tell me a story.“Where have you been, you naughty child?”“I won’t tell you, mother.”That’s what you and I would say then.【客观题】1) When I should laugh to myself and keep quiet, what should I do then?2) When my mother read books, what would I do?【主观题】1) Have you ever played some games with your parents?

Every day, the camels went into the jungle to graze on the jungle’s tender and fresh grass. On the way to and from the jungle, the baby camel who wore a bell around the neck walked behind the group. The other camels would always tell, advise and warn him not to stay behind the group. Otherwise, only he would be responsible for its dire consequences. But he wouldn’t listen to anybody because he thought he was the smartest camel and he wore a bell around his neck to show he was different from others. And he always thought he could solve every problem smartly.One day, all camels were grazing in the jungle. As usual, the baby camel stayed behind the other camels. A lion was walking in the jungle in search of food. He heard the bell’s sound and followed in the direction from where the sound was coming.

Spanking Children Brings Long-term HarmFor some parents, spanking a child who is not good is a common thing. In fact, they may think that this is good for children and will teach them to behave in the future.However, a leading group of child health scientists thinks that it is wrong. These experts say that spanking is not useful and it may even bring long-term harm to the child. These harms are “bad temper, brain changes, and hurting oneself when kids grow up.”It is true that not every child who is spanked will have these problems later in life. Even if many children who were spanked become happy, healthy adults, there is a lot of studies showing that spanking is not useful, good and even may bring long-term harm.【客观题】1) Why do many parents spank their kids?2) What harm will spanking bring children?【主观题】1) Have you ever been spanked by your parents? Why?2) What do you think of physical punishment?13. Birds Learn Languages to Protect ThemselvesPeople speak thousands of languages in the world today.

Did you know that the first came from China?About two thousand years ago, a young girl called Tan planted a flower. The flower grew so tall and it started to fall over. Tan had a clever idea. “I’ll put a bamboo stick in the ground next to the flower. I’ll tie the flower to the bamboo stick. The bamboo will stop the flower falling over.” Tan went into a field and cut a piece of bamboo. It was a hot and windy day. The wind blew the bamboo out of Tan’s hand onto the earth.Tan saw the bamboo stick had a hole in it. She took the silk ribbon from her hair and put it through the hole. She carried the bamboo by the ribbon. The wind blew very hard, and the bamboo flew up in the air over Tan’s head. Tan went home, holding the silk ribbon in her hand and pulling the bamboo through the air. That’s how the first kite was invented.The first kite was called muyuan, a wooden kite. That is because it was made from bamboo wood. When paper was invented more than 1,800 years ago, people began to make zhiyuan. Do you know how to say zhiyuan in English? Do you know why kites are called fengzheng? About 1,000 years ago people began to put bamboo whistles on kites. When the kites flew high in the air, the bamboo whistles made a noise like a zither. That’s why the Chinese name for kite s is fengzheng. 【客观题】1) Who made the first kite?2) Why is the Chinese name for kites fengzheng?【主观题】3) Have you ever played a kite? Do you like it?4) What do you do in your spare time?15. Where Do Things Come From?When you drink, eat or use something, it is interesting to think about where the thing comes from and how it comes to you. For example, think about your shirt. If your shirt is made of cotton, then the cotton comes from a cotton plant. First, a farmer must plant the seed in the ground and give it lots of water and sunlight. Then, the seed will grow for many months. The cotton that is used to make clothes protects the seeds.The flower has many seeds inside of it, so we use a special machine called a cotton gin to remove them easily. After the farmer collects the cotton, it is made into a long piece of string. The string is sold to a clothing factory, and the factory uses the string to make shirts.When the shirt is finished, they put the shirt into a box. Then, the box of shirts is put into a truck and delivered to a store where you can buy your shirt.The shirt you are wearing now took a lot of time and a lot of people to end up on your body.【客观题】1) The flower has many seeds inside of it. How can we remove them?2) How do factories make shirts?【主观题】1) How long will you keep your shirts and wear it? For one summer or until it is broken?2) It is difficult to make things. How should we treat the things we have?。

1、 编程解决如下问题:鸡翁一,值钱五;鸡母一,值钱三;鸡雏三,值钱一。百钱买百鸡, 问鸡翁,鸡母,鸡雏各几何?(20分)
2、 编程实现:有二维数组a[3][3]={{1.3,2.7,3.6},{2,3,4.7},{3,4,1.27}},将数组a的每一行元素均除以该行上绝对值最大的元素,按行输出新数组。(20分)
请务必按照试卷要求提交指定的文件,不得包含非题目要求的过程文件和临时文件,不得包含本试题文件和试题素材。
注意:凡违反上述规定的考生,其成绩一律按零分处理。
题目命名要求:请将编写好的源程序以题号命名,例如第1题的源程序保存为“1.C” 。
重要提示:由于时间有限,请考生首先保证编写的程序在Wintc环境下可以编译通过并执行,并在此基础上完成考题要求的全部功能,以免因编译不通过影响考生的考试成绩。
