（共15小题；每小题2分，满分30）ACheck out our tsunami facts and learn some interesting info rmation related to these great walls of water that can cause s o much destruction. Find out what causes tsunamis and read about some recent examples of tsunamis that have occurred around the globe.●The Japanese word for tsunami means harbor wave.●Tsunamis are sometimes referred to as tidal (潮汐的) waves but this term has fallen out of favor because tsuna mis are not related to tides.●Tsunamis are huge waves of water that are usually caus ed by earthquakes or volcanic eruptions.●As a tsunami approaches the shore (海岸), water may move back from the coast. If it is shallow (浅的) enough the water may be pulled back hundreds of meters. If you are in the area, you can know that a tsunami is on the way when you see this phenomenon.●Regions in tsunami danger zones often have warning sys tems in place to give people as much time as possible to move to a safe place.●When tsunamis hit shallow water (often near the coast) th ey slow down but increase in height.●An earthquake in the Indian Ocean off Indonesia in Dece mber 2004 caused a tsunami that killed over 200,000 people i n 14 countries.●In March 2011, the Tohoku earthquake off the eastern co ast of Japan caused a tsunami that was a major factor in the death of over 15,000 people.●The tsunami waves created by the Tohoku earthquake re ached heights of over 40 meters in some areas, wiping out co astal towns and causing a number of nuclear accidents.1.How many causes of tsunamis are mentioned in the text?A.One.B.Two.C.Three.D.Four.2.In the Tohoku earthquake over 15,000 people died mainly because of _____.A.the earthquake itselfB.the lack of warning systemsC.the tsunami caused by the earthquakeD.the nuclear accidents caused by the tsunami3.Which of the following is TRUE according to the passage?A.Over 200,000 people were killed in 14 countries because of the earthquake in Dec.2004.B.Sometimes tsunamis are said as tidal waves, because they are related to tides.C.The warning systems in some regions help people move to a safe place.D.If you see water move to the coast, there will be a tsunami on the way.4.The text is developed mainly by _____.A.listing some factsB.giving some examplesC.providing some numbersD.making some comparisonsBThere are robots all around us. Some do very complicated jobs like flying airplanes and driving subway trains. And some do one simple job. When an automatic washing machine is switc hed on, water pours in. The machine waits until the water is w arm enough for washing clothes. It does this by “feedback” (反馈). Information about what is happening is feed back into the robot to tell what to do next. Our eyes, ears and other senses are our feedback. They tell us what is going on around us. So robots are like human beings in two ways.They work and they have feedback.In some ways robots are better than human beings. They wor k quickly and do not make mistakes. They do not get bored d oing the same job over and over again. And they never get tir ed. So robots are very useful in factories. They can be taught to do many different jobs. First their electronic brain must be s hown how the job is done. A person moves the robot’s“arms”and “hands” through each part of the job.The most intelligent robots can move and see. Their eyes are cameras. Their fingers can feel shapes and sizes of the object s. These robots have computer brains linked to their eyes and fingers, which control their actions. The expensive “Times Ne w Roman” --- The most intelligent robots are used in scientific research. They do such job as handling radioactive materials.5. What does the author seem to inform you about robots?A. They should be greatly improved.B. They will probably take over in the future.C. They are very helpful and useful to humans.D. They are machines that break down a lot.6. The fact that a robot never gets bored doing the same job means that_____.A. it is very much like human beingsB. it can do boring jobs for peopleC. it will never bore peopleD. it will work much better than human beings7. The robots used for scientific research________.A. are not very cleverB. are very cheapC. are very bigD. are very costly8. According to the passage, which of the following statement s is TRUE?A. In most ways robots are better than human beings.B. Robots have eyes, so they can see.C. Scientists sometimes do scientific research by using the int elligent robots.D. Robots can work but they have no feedback.CEdgar felt quite excited at the thought of his first swim of the summer. With the sun shining down so strongly, the sea was certain to be warm enough. He walked quickly along the sea-front towards the steps that led on to the sands. He smiled ch eerfully at the passers-by. He had just smiled and raised his hat to an elderly lady wh en a man with a camera caught his arm and stopped him. Ed gar heard a little buzzing noise from the camera.“Y our photograph, sir, in glorious colour in just one moment if you please,” said the man in one breath. Then the buzzing stopped, and he held the photograph in his hand and was wa ving it to and fro. In a moment he handed it over,and Edgar sa w the bright blue splash of his shirt half filling the picture.“Seventy pence, sir,” the man said. “It’s the bargain of your holiday.”“Seventy pence,’’ Edgar repeated, mildly. “For this?” He star ed at the photographer.“They’re normally eighty-five, sir,but for a single subject I make a cut-price offer. It’s the best value you’ll get in Chadwell. ”“You’ll have to make a better offer,” Edgar said. It was a goo d photo though, he thought, so bright and clear. His hat was h eld high, and he was smiling broadly at the old lady,whose ar m and handbag came into a lower corner. He had had no idea that he was being snapped. He thought he was really quite a good-looking chap.“That’s as good as any studio job that would cost you poun ds•” said the cameraman. “It’s better in a way because it’s so natural. Only seventy pence,sir. ”“I've never paid so much for a snap in my life. It simply isn’t worth that kind of money. It’s not as if I need the thing. Look, I’ll give you twenty-five.”“No, I can do that. Each of these instant colour shots costs me 50p ~ that's the price of the blank frame,so you see…”“Criminal,criminal,” Edgar broke in. “You want a profit of fort y per cent. Well, not at my expense, Tm afraid. Til give you yo ur 50p and that5s that."“Le t me see,then. ” The man suddenly took the photograph out of Edgar’s hand. “I can’t waste any more time with you. It’s 70p or I keep it. ”“Keep it,” Edgar said. He turned,looked out to the sea, and then walked quickly away.9.Why do you suppose Edgar was in Chadwell?A.It was his hometown.B.He was there on holiday.C.He was in the making of a film.D.He was there to have his photograph taken.10.Edgar smiled at and raised his hat to the lady because .A.he thought he recognized herB.he wanted the photograph to be amusingC.she was having her photograph takenD.he was feeling excited and cheerful11.What did Edgar think of the photo?A.He thought it made him look like a criminal.B.He liked it but thought it was too dear.C.It annoyed him because he hadn’t expected it.D.He thought it was a bargain at the price.DSurveys of American teenagers find that about half of them do not get enough sleep on school nights. They get an average of sixty to ninety minutes less than experts say they need.One reason for this is biology. Experts say teens are biologi cally programmed to go to sleep later and wake up later thanother age groups. Yet many schools start classes as early as seven in the morning.As a result, many students go to class f eeling like sixteen-year-old Danny. He is an active teen—except in the morning. “Getting up in the morning is pretty terri ble. I’m just very out of it and tired. Through the first and seco nd period I can hardly stay awake,” he said.Michael Breus is a psychologist (心理学家)). Teens,he says, need to sleep eight to nine hours or even nine to ten hours a night. He says sleepy teens can experien ce a form of depression (抑郁)that could have big effects on their general well-being. This depression can affect not just their ability in the cl assroom but also on the sports field. So what can schools do about sleepy students? The psychologist says one thing they can do is start classes later in the morning. Studies show that students can improve by a full letter grade in their first and se cond-period classes.Eric Peterson is the head of St. George’s School in the nort heastern state of Rhode Island. He wanted to see if a thirty-minute delay (推迟)would make a difference. It did. He says visits to the health centre by tired students decreased by half. Late arrivals to th e first period fell by a third. And students reported that they w ere less sleepy during the day. Eric Peterson knows that changing start times is easier at a small, private boarding school lik e his. But he is hopeful that other schools will find a way to do the same.12.The underlined word “this” in the second paragraph refers t o .A.children’s getting up lateB.children’s staying upC.children’s not getting enough sleepD.children's sleeping habits13.The passage mentions the story of sixteen-year-old Danny to show how .A.he hates getting up in the morningB.teens can be affected by a lack of sleepC.he turns from an active boy to a tired school childD.teens hate school14.The last paragraph tells us .A.it’s not easy to change the sleeping habitsB.a thirty-minute delay in classes would make no differenceC.students in St. George’s School can be late for classD.starting classes later in the morning can be good for teens15.What would be the best title for the passage?ter classes,less sleepy teensB.Early birds catch wormsC.Early to bed and early to riseD.Less classes,more happiness第二节七选五(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中有两项为多余选项。

第Ⅰ卷第一部分 (共3节，满分90 分)第一节阅读理解(共20小题；每小题2分，满分40分)AThe cars were honking(鸣叫)on the road one morning as I was walking to the park。
I walked on and soon found the cause－a little taxi that had got stuck in the middle of the road．There was sweat on the driver's face as he tried to start the engine again and again－nothing happened．“No petrol．”I said to myself and then found myself getting an gry．“Why doesn't the fool move his taxi to the side?”I though t, so did all the others who honked and shouted．He got up tiredly, and the passenger in the taxi got out．He w as a young man in a white shirt, who watched the driver try to push it to the side．“Stupid guy!”I said．“Can't he lend a helpi ng hand?”I watched as the poor driver pushed it to the side．Cars, buse s and trucks went past cursing(咒骂)the poor man．The young man took another taxi and went off．The taxi driver began mending his taxi．“Stupid passenger!”I said to him．“He didn't help you!”.The taxi driver slowly got up ．“Sir!” he asked, “Did you?” I looked at him guiltily, then look ed away, and walked away fast, asking myself, “Did I help the poor man push his taxi?”What had I been doing as the traffic jam took place?How had I helped deal with the problem?Did I help the poor man push his taxi?I'd done my bit, with my mouth．But never had I mov ed to solve the problem．I was shocked with guilt as I heard h im asking,“Sir!Did you?”1.Why did a traffic jam happen on the road when the author w as walking to the park?A. There was too much traffic in the street.B. Truck drivers attempted to go ahead of others.C. A taxi driver couldn't start his engine.D. A young man wasn't good at driving.2.The underlined sentence “Did you ?” in para.5 means “_________.”A.Did you get angry?B. Did you help him?C. Did you help me ?D. Did you need a help?3.Why did the author feel guilty?A. Because he blamed the driver wrongly.B. Because he didn't help the driver, either.C. Because he tried to help but failed in the end.D.

From the incident, the author learnt a lesson that we should _________.A. criticize those who don't helpB. hurt the self-respect of others no moreC. think more of those who are in needD. stop talking and start to helpBWhen I saw my 10-year-old avoiding the dirty plate in the sink or my 8-year-old feeling uncomfortable about the wet sand in her hands，I'm reminded of a time when I was unwilling to get my hands a little dirty．My parents owned a 500-acre farm in Montana to raise animals，such as cows，sheep，horses and so on．It was during the time of new life （a newborn lamb or a calf） that my favorite childhood mem ory took place．One exceptionally cold day，I was checking on the sheep with my mother when she spieda ewe（母羊） in trouble．The poor thing was trying to deliver her baby lamb and needed our help．My mother calmly held the ewe's head and instructed me to grab hold of the two protruding（突出）legs．I hesitated，and must have had quite a look of panic on my young face．T he slimy little things were definitely not something I wanted to touch．But I worked up my courage and wrapped my fingers around them．I can still recall the feel of unexpectedly weak l egs and their sharp little hooves as if it happened yesterday． My heart pounded in fear and excitement as I pulled with all my strength．The lamb was delivered safely，and I'd never seen anything so beautiful．I was no stranger to seeing farm animals being born，but to have a hand in it was something I treasured then and w ill treasure forever．I remember feeling excited with delight to see “my lamb” being licked clean by her mother，and I'm sure everyone got very tired of hearing me tell and ret ell my heroic story．Looking back，I'm so glad that I didn't refuse to get my hands dirty．If I had ，the wonderful moment and the precious memory would have been lost．5．What impressed the writer most during her childhood？A．Her dirty little hands．B．Her parents’ large farm．C．Helping deliver a baby lamb．D．Raising animals on the farm．6．How did the author feel when she was asked to help a ew e deliver her baby？A sympathetic． B．rather frightened．C．quite astonished ． D．highly delighted．7．What point does the author try to make in the last paragra ph？A．It is not unusual to see a new life coming into the world ．B．It is not easy to make up and tell a heroic story in daily li fe．C．Memories formed during childhood are worth valuing all life long．D．You need to get your hands dirty to experience somethi ng precious．8．What could be the best title for the passage？A．A Valuable Life Lesson B．A Tidy and Clean Chil dC．A Ewe Delivering her Baby D．A Beautiful Newbor n Lamb．CIf you want to skip the misery (痛苦) that comes with fighting a seasonal cold or flu, a new rese arch explains why sleep is some of the best preventive medici ne. We already knew that not getting enough sleep can lead t o an increased risk of getting sick, but Nathaniel Watson, a ne urologist and sleep specialist at the University of Washington School of Medicine, said this new research helps explain why. Sleeping poorly can block specific genetic processes in the ce lls that make up your immune system, which is responsible for fighting off infections and diseases, according to the new stu dy. “Your immune system is not functioning the way it was me ant to when you are deprived of sleep,” Watson said. This stu dy is the first one that Watson and his colleagues are aware of that looks at what happens to the immune system’s DNA wh en you’re not getting adequate sleep.The researchers followed 11 pairs of identical twins for the stu dy. One twin reported sleeping at least seven hours per night, while the other slept approximately one hour less per night. L ooking at identical twins helped control the fact that sleep nee ds vary by person, Watson explained. Genes account for abo ut 50 percent of our sleep needs, meaning identical twins are the best-case scenario (方案 ) for getting a good comparison. The researchers took blood samples at the end of the study, which revealed that the immune system of the twin who slept l ess was less active than the twin who slept more. Those who slept less were actually making fewer proteins, the molecules that our bodies run on. “They had an under-performing immune system,” Watson said of the shorter sleep ers, “which would put them at higher risk of getting sick.”To control other potential factors that could affect sleep need and immune health, the researchers didn’t include people fro m the study who had diabetes, depression or other mental he alth problems and sleep disorders. They also left out shift wor kers, smokers, drug users and drinkers.9. What do the underlined words in Paragraph 2 mean?A. change sleep pattern.B. benefit from sleep.C. have to sleep.D. lack sleep.10. Why did the researchers choose identical twins for the stu dy?A. To find participants more easily.B. To make the results more accurate.C. To make the study more interesting.D. To show sleep needs vary by person.11. What does the author most probably want to show in the l ast paragraph?A. Many factors can lead to sleep disorder.B. The findings of the study can be reliable.C. Poor sleep could lead to many problems.D. The findings of the study remain to be tested.DMy 16-year-old son, Anton, had gone to the local swimming hole．Most of the kids swim there, and there are plenty of rocks for them to use as safe harbors, so I had no fears for his safety．Still, the firefighter's first words "You need to come up here to the Stillwater River" made me catch my breath, and his follow-up words gave me relief: “ Your son is OK．”When I got to the river, I immediately saw the fire truck, ambulance and Anton, wrapped with a towel about his shoulders, sit ting quietly on a low platform of the fire engine．I hurried over to him. "You OK?"I asked．“Yeah," was all he said．But my eyes begged for an explanati on. I didn't get it from my son, however, who tends to play his cards close to his vest．The story was this: A woman was being swept under water. H earing the cries, Anton and his friend Tyler, without hesitation, swam out to her, and brought her safely to shore．In an age in which the word "hero" is broadcast with abandon and seemingly applied to anyone who make it through the day , I realized the real thing in my son．The teens are stubborn a nd self-centred, but that didn't mean they have no desire to do good ．Still shocked by my son's daring, I drove him home.Along the way, I tried to dig out some more information from him - but h e had precious little to say.The only words he said were,“What's for supper?"I spent some time alone that evening, thinking about the trage dy that might have been. The next morning, when Anton got u p, I half wanted him to tell me the story.But all he did was toast some bread, pull himself together, and head for the door to s tart a new day. Watching from the window, I was reminded th at still water often runs deep.12．Why did the mother allow her son to swim there?A．He was an excellent swimmer.B．The water of the river is shallow.C．He was old enough to swim.D．The rocks can be of help if there's danger.13．The underlined part "who tends to play his cards close to his vest" probably means ________A．Anton is a boy fond of swimming with other kids B．Anton is unwilling to tell others what he thinksC．Anton always has a desire to help othersD．Anton seldom changes his mind14．In the mother's eyes, what her son did was__________ A．dangerous but interestingB．meaningful but difficultC．unexpected and courageousD．awful and absurd15．What might be the best title for the passage?A．My Son, My Hero B．Anton, A Silent BoyC．A Good DeedD．A Proud MotherEAre you looking for a young adult novel? If you’ re, here are s ome good choices for you.The Harry Potter SeriesIf you’re a grown-up and still haven’t read the Harry Potter novels, you don’t kn ow what you’re missing. J.K.

会宾客大宴，于厅事之东北角，施八尺屏障，口技人坐屏障中，一桌、一椅、一扇、一抚尺而已。
众宾团坐。
少顷，但闻屏障中抚尺一下，满坐寂然，无敢哗者。
遥闻深巷中犬吠，便有妇人惊觉欠伸，其夫呓语。
既而儿醒，大啼。
夫亦醒。
妇抚儿乳，儿含乳啼，妇拍而呜之。
又一大儿醒，絮絮不止。
当是时，妇手拍儿声，口中呜声，儿含乳啼声，大儿初醒声，夫叱大儿声，一时齐发，众妙毕备。
满坐宾客无不伸颈，侧目，微笑，默叹，以为妙绝。

于是宾客无不变色离席，奋袖出臂，两股战战，几欲先走。
忽然抚尺一下，群响毕绝。

（3 分）若辗转申报民岂得活乎上有谴我任之11.结合原文，说说郑板桥是一个怎样的人（3 分）（三）成为你自己周国平（10 分）①童年和少年是充满理想的美好时期。
如果我问你们，你们将来想成为怎样的人，你们一定会给我许多漂亮的回答。
譬如说，想成为拿破仑那样的伟人，爱因斯坦那样的大科学家，曹雪芹那样的文豪等等。
这些回答都不坏，不过，我认为比这一切都更重要的是：首先要成为你自己。
②姑且假定你特别崇拜拿破仑，成为像他那样的盖世英雄是你最大的愿望。
好吧，我问你：就让你成为拿破仑，生长在他那个时代，有他那些经历，你愿意吗？你很可能会激动得喊起来：太愿意啦！我再问你：让你从身体到灵魂整个儿都变成他，你也愿意吗？这下你或许有些犹豫了，会这么想：整个儿变成了他，不就是没有自己了吗？对了，我的朋友，正是这样。
那么，你不愿意了？当然喽，因为这意味着世界上曾经有过拿破仑，这个事实没有改变，惟一的变化是你压根儿不存在了。
③由此可见，对于每一个人来说，最宝贵的还是他自己。
无论他多么羡慕别的什么人，如果让他彻头彻尾成为这个别人而不再是自己，谁都不肯了。
也许你会反驳我：你说的真是废话，每个人都已经是他自己了，怎么会彻头彻尾成为别人呢？不错，我只是在假设一种情形，这种情形九年级语文第 2 页共4 页不可能完全按照我所说的方式发生。
不过，在实际生活中，类似情形却常常在以稍微不同的方式发生着。
世上有许多人，你可以说他是随便什么东西，一种职业、一种身份、一个角色，或别的什么，惟独不是他自己。
如果一个人总是按照别人的意见生活，没有自己的独立思考，总是为外在的事务忙碌，没有自己的内在生活，那么，说他不是他自己就一点没有冤枉他。
因为确确实实，从他的头脑到他的心灵，你在其中已经找不到丝毫真正属于他自己的东西了，他只是别人的一个影子或事务的一架机器罢了。
④那么，怎样才能成为自己呢？这是真正的难题，我承认我给不出答案。
我还相信，不存在一个适用于一切人的答案。
我只能说，最重要的是每个人都要真切地意识到他的“自我的宝贵”，有了这个觉悟，他就会自己去寻找属于他的答案。
在茫茫宇宙间，每个人都只有一次生存的机会，都是一个独一无二、不可重复的存在。
正像卢梭所说的，上帝把你造出来后，就把那个属于你的特定的模子打碎了。
名声、财产、知识等等都是身外之物，人人都可求而得之，但你对人生的独特感受是没有人能够替代的。
你死之后，没有人能够代替你再活一次。
如果你真正意识到这一点，你就会明白，活在世上，最重要的就是活出你自己的特色和滋味来。
你的人生是否有意义，衡量的标准不是外在的成功，而是你对积极人生的独特领悟和坚守。
坚持这一标准，你的自我才能闪放出个性的光华。
⑤在历史上，每当世风腐败之时，人们就会盼望救世主出现。
其实，救世主就在每个人的心中。

14.作者论述的“你自己”具有怎样的特点？怎样才能成为“你自己”（4 分）（四）没有发芽的种子邱海泉（17 分）①散步的时候，心情总是松弛着，洒脱如脱线的风筝，一任世界上的一切像毫无意义的微风似的从眼前滑过。
而从前所有的不快早都遥远得成了另一个世界的事。
时不时，眼前一亮，也说不定有什么东西让人心头一动。
比方说一只小狗十分顽皮地向你撒娇吠叫，比方说一滴挂在枝头上的晶莹剔透的小露珠向你暗送的秋波……那天，我却被一大片开得如火如荼的喇叭花吸引住了。
②我不知何时已经信马由缰地走到郊外了。
③那是几十年前的事了。
那时我还是个村童毛孩。
一天早上跟父亲下地锄草，就在一个土壕里看见了那片开得正艳正好的花儿。
我禁不住诱惑，跑下壕去，蹲在地边，手摩挲起花儿，半天不想起来。
父亲却早在我身后喊了起来：别踩坏花儿，那是你大伯家种的二丑。
我这才知道这一地可爱的花儿原来是一味中药材。
④那一霎，伫立在那儿，我眼里看的是盛开的花儿，心里纷飞的却是打开了尘封的往事。
久久地流连盘旋在那儿，我突然看见二丑花成熟后洒落在地上的种子。
我小心翼翼地捡拾着，心里想，待到来年开春，我要把它种到阳台上去，这样我们就可以形影不离地天天厮守在一起了。
⑤在我的期盼和浇灌中，喇叭花的幼苗一天天长高了。
它的枝蔓那么快就爬满了阳台，真令人惊讶!它的花不只开满了我的花园和阳台，而且也弥漫浸透了我生命的空间——我一有空就站在花蔓下，一任那落英像春雨一样洒在我的头上。
邻居们也都来欣赏参观我的花儿，而且连连称赞说：真好看真好看哟。
有个朋友还拿起照相机拍了照片，刊登在了当地的报纸上……⑥一天，女儿突然从抽屉里翻出一个小信封说：这里面是什么，没用的话我扔了?我一看，说：那是没种完的喇叭花种子，放下，扔什么。
她说：今年已经有新种子了，还要它干什么……尽碍九年级语文第 3 页共4 页事儿，我扔了。
说着顺手丢进了垃圾篓。
⑦我的心突然随着那花种子的下落揪了一下。
