(人教版)高中英语必修二Unit 3 Computers 单元测试题2(含答案)
Unit 3 Computers 单元测试题2第二部分：阅读理解（共两节，满分40分）第一节（共15小题；每小题2分，满分30分）阅读下列短文，从每题所给的四个选项（A、B、C和D）中，选出最佳选项。
ADear students,Most of us get some exercise walking or riding our bikes to school, but that just isn't enough. Why not get into shape by playing the most popular sport in the world — soccer?Two weeks ago, Ms. Goldstein, the physical education teacher, posted a notice about an exciting new soccer club (for Grades 3-5). To join, all you have to do is sign your name and be at school for the fun of it on Saturday mornings. You'll make new friends and share information about famous teams and players.Ms. Goldstein will teach, so you'll learn basic skills and new techniques (技巧) to improve your game. That's good news because soccer is a game you can love three seasons a year. The only time you can't play is when there is snow.However, it is hard to believe that only nineteen people signed up for the new club. Maybe kids don't want to give up their Saturday mornings. But if you think about how we spend Saturday mornings now, soccer looks good. Doing housework and watching TV are not as much fun as playing soccer with friends. If you didn't sign up because you've never played soccer before, don't worry. Beginners are welcome and Ms. Goldstein will give you more help.Just act now! The equipment is cheap. All you have to bring is your feet.The Students' Union21. We can learn from the text that the club _____.A. was first set up for beginnersB. is just open to students of Grade 3C. was probably started two weeks agoD. is available every day except for Sundays22. What does the author think of playing soccer?A. It makes people famous easily.B. It does students a lot of good.C. It is a very dangerous game.D. It is as interesting as watching TV.23. The author writes the text mainly to _____.A. talk about how to be an excellent playerB. encourage the students to join a soccer clubC. advise the students to take more exerciseD. introduce Ms. Goldstein to the studentsBOne day Kavya and I were playing tennis and the ball went into a man's house. Then we went to his house and asked if he could give us our ball. He said, “No”. We felt helpless. But suddenly we came up with an idea. There was a water tank (水箱) behind the man's house. I told Kavya, “We can climb onto the water tank and jump over the gate.” Kavya agreed, but we were both wearing skirts. We couldn't climb in those. “We can get it back tomorrow,” said Kavya.The next day we went there with Kavya's brother Vijay. He said, “Shout loudly if you need me.” Kavya climbed onto the water tank first and then she climbed down into the man's house. I followed her. We were looking under a bed for the ball when we heard a noise. It was Vijay. “Mother is calling you,” he said in a low voice.We hurried out taking the lost ball with us. Along with the ball was a surprise! But we had to leave the house quickly. When we reached Kavya's house, the TV was on. It was news time. I couldn't believe my ears when it said that 20 gold bars were stolen from a gold shop. They showed a picture of the gold bars, which were exactly like the one we had seen in the man's house.We told the story to Kavya's mother right away, and she called the police. Soon the police caught the man. They found all the gold bars in his house. A few days later a policeman came to us and said, “Thank you for helping us catch the guy. Here is abag for all of you.” When we opened it, it was full of storybooks and lovely toys. Standing beside us, Kavya's mother was all smiles.24. The children decided to climb over the water tank _____.A. after they were refused by the manB. because their ball fell onto the tankC. to see who was brave enough to do thatD. because they wondered who the man was25.

Better late than never.B. The day has eyes, the night has ears.C. A bad thing never dies.D. Friendship is love with understanding.CBorn in 1965, Shania Twain was the second of five children in her family. At the age of two, she moved with her mother and two sisters to Timmins, a town northof Toronto. When Shania was eight years old, her mother took her to many different bars, clubs and concerts to perform (表演). In high school, Shania joined a local band (乐队), with which she often performed. After that, Shania moved to Toronto, where she continued singing.When Shania was 21 years old, her parents were killed in a car accident. She had to take over the role of parent to her younger siblings (兄弟姐妹). Taking care of two teenage brothers and a sister was a Gordian knot. Suddenly, she had to pay the bills, keep food on the table, and make a living. Anyway, Shania managed to pay the bills by singing here and there.In 1991, Shania went to Nashville, the home of the country music industry. In 1993, she recorded Shania Twain, her first CD. In 1995, her next CD, The Woman in Me, which had eight hit songs, sold more than ten million copies. Her third CD, Come on Over, was also popular and she had another hit song.Shania and Robert Lange, a famous producer, got married in 1993. After finishing her 2000 world tour, she decided to take a break from performing. In August 2001, they had a lovely son, whom they named Eja. After September 11th, Shania decided to spend more time on her family and stayed at home until the fall of 2002.

All his friends already had one, so his mom and dad agreed. During the first few weeks, Jason spent a lot of time in front of his computer because he had to learn how it worked. He was really interested in learning all about it and he even started writing computer programs himself.One day Jason found a website where he could play chess either against the computer or against other people from all over the world. From then on, Jason seemed to have just one interest in life, his computer. Whenever his parents told him that he was spending too much time with his computer, Jason went into denial. He did not think that he had a problem at all.Then the unthinkable happened: Jason's computer broke down. But his parents decided not to buy him a new one. Jason said that he needed a computer for school, and he promised that he'd spend less time with it. But his parents refused to give in. Finally, Jason felt so hopeless that he took the only way out and killed himself.Robert Johnson, a psychologist (心理学家) on the subject, says, “Computer addiction (沉溺) is an illness that can influence anyone of us. Nowadays, increasing numbers of people are spending more and more time working with computers. While this isn't a problem for most users, some people, especially teenagers, often use thecomputer to get away from the real world. This is especially true of shy people. For them, meeting people online is a way of hiding their true selves. In cyberspace, they can be whoever they want to be and create their own virtual (虚拟的) world. But what happens when they can no longer enter their virtual world?”32. Why did Jason want to buy a computer according to Paragraph 1?A. To play chess.B. To make friends.C. To avoid being an outsider.D. To write computer programs.33. By saying “Jason went into denial”, the author means _____.A. Jason would not listenB. Jason enjoyed himselfC. Jason would turn it offD. Jason changed his mind34. What was Jason's relationship with his parents like when his computer broke down?A. Fine.B. So-so.C. Terrible.D. Unknown.35. In Robert Johnson's opinion, _____.A. it is impossible to beat computer addictionB. shy people get addicted to computers easilyC. teenagers should stay away from computersD. computers are getting us into serious trouble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。

【解析】连接B′C，则△AB′C为等边三角形，设AD＝a，则B′D＝DC＝a，B C AC'==，所以∠B′DC＝90°．故选A．7．【答案】B【解析】对于①，∵P A⊥平面ABC，∴P A⊥BC，∵AB为⊙O的直径，∴BC⊥AC，∴BC⊥平面P AC，又PC⊂平面P AC，∴BC⊥PC；对于②，∵点M为线段PB的中点，∴OM∥P A，∵P A⊂平面P AC，∴OM∥平面P AC；对于③，由①知BC⊥平面P AC，∴线段BC的长即是点B到平面P AC的距离．故①②③都正确．8．【答案】C【解析】由已知AC＝AB，E为BC中点，故AE⊥BC，又∵BC∥B1C1，∴AE⊥B1C1，故C正确．故选C．9．【答案】D【解析】∵m∥α，m∥β，α∩β＝l，∴m∥l．∵AB∥l，∴AB∥m．故A一定正确．∵AC⊥l，m∥l，∴AC⊥m．故B一定正确．∵A∈α，AB∥l，l⊂α，∴B∈α．∴AB⊄β，l⊂β．∴AB∥β．故C也正确．∵AC⊥l，当点C在平面α内时，AC⊥β成立，当点C不在平面α内时，AC⊥β不成立．故D不一定成立．故选D．10．【答案】B【解析】如图所示，作PO⊥平面ABC，则O为△ABC的中心，连接AP，AO．1sin 602ABC S =︒=11194ABC A B C ABC V S OP OP -∴=⨯==，OP ∴=213OA ==，∴tan OP OAP OA ∠=，又02OAP π<∠<，∴3OAP π∠=．故选B ．11．【答案】D【解析】因为AH ⊥平面A 1BD ，BD ⊂平面A 1BD ，所以BD ⊥AH ． 又BD ⊥AA 1，且AH ∩AA 1＝A ．所以BD ⊥平面AA 1H ．又A 1H ⊂平面AA 1H ．所以A 1H ⊥BD ，同理可证BH ⊥A 1D ，所以点H 是△A 1BD 的垂心，故A 正确． 因为平面A 1BD ∥平面CB 1D 1，所以AH ⊥平面CB 1D 1，B 正确．易证AC 1⊥平面A 1BD ．因为过一点有且只有一条直线与已知平面垂直，所以AC 1和AH 重合．故C 正确．因为AA 1∥BB 1，所以∠A 1AH 为直线AH 和BB 1所成的角． 因为∠AA 1H ≠45°，所以∠A 1AH ≠45°，故D 错误．故选D ． 12．【答案】B【解析】A 错误．理由如下：过A 作AE ⊥BD ，垂足为E ，连接CE ，若直线AC 与直线BD 垂直，则可得BD ⊥平面ACE ，于是BD ⊥CE ，而由矩形ABCD 边长的关系可知BD 与CE 并不垂直．所以直线AC 与直线BD 不垂直．B 正确．理由：翻折到点A 在平面BCD 内的射影恰好在直线BC 上时，平面ABC ⊥平面BCD ，此时由CD ⊥BC 可证CD ⊥平面ABC ，于是有AB ⊥CD ．故B 正确． C 错误．理由如下：若直线AD 与直线BC 垂直，则由BC ⊥CD 可知BC ⊥平面ACD ，于是BC ⊥AC ，但是AB <BC ，在△ABC 中∠ACB 不可能是直角．故直线AD 与直线BC 不垂直．由以上分析显然D 错误．故选B ．二、填空题(本大题共4个小题，每小题5分，共20分，把正确答案填在题中横线上)13．【答案】④【解析】①中b 可能在α内；②a 与b 可能异面或者垂直；③a 可能与α内的直线异面或垂直．14．【答案】B 1D 1⊥A 1C 1(答案不唯一)【解析】由直四棱柱可知CC 1⊥面A 1B 1C 1D 1，所以CC 1⊥B 1D 1，要使B 1D 1⊥A 1C ，只要B 1D 1⊥平面A 1CC 1，所以只要B 1D 1⊥A 1C 1，还可以填写四边形A 1B 1C 1D 1是菱形，正方形等条件． 15．【答案】①③【解析】由条件可得AB ⊥平面P AD ，∴AB ⊥PD ，故①正确；若平面PBC ⊥平面ABCD ，由PB ⊥BC ，得PB ⊥平面ABCD ，从而P A ∥PB ， 这是不可能的，故②错；1·2PCD S CD PD =△，1·2PAB S AB PA =△，由AB ＝CD ，PD >P A 知③正确；由E 、F 分别是棱PC 、PD 的中点，可得EF ∥CD ，又AB ∥CD ，∴EF ∥AB ， 故AE 与BF 共面，④错． 16．【答案】a >6【解析】由题意知：P A ⊥DE ，又PE ⊥DE ，P A ∩PE ＝P ，∴DE ⊥面P AE ，∴DE ⊥AE ．易证△ABE ∽△ECD ．设BE ＝x ，则A B B EC E C D=，即33xa x =-．∴290x ax +=-， 由0∆>，解得a >6．三、解答题(本大题共6个大题，共70分，解答应写出文字说明，证明过程或演算步骤)17．【答案】平行，见解析．【解析】直线MN ∥平面A 1BC 1．证明如下：∵M ∉平面A 1BC 1，N ∉平面A 1BC 1．∴MN ∉平面A 1BC 1． 如图，取A 1C 1的中点O 1，连接NO 1、BO 1．∵11112N D O C ∥，1112M D B C ∥，∴1NO MB ∥．∴四边形NO 1BM 为平行四边形．∴MN ∥BO 1．又∵BO 1⊂平面A 1BC 1，∴MN ∥平面A 1BC 1． 18．【答案】（1）见解析；（2）见解析． 【解析】（1）∵C 1C ⊥平面ABC ，∴C 1C ⊥AC ．∵AC ＝9，BC ＝12，AB ＝15，∴AC 2＋BC 2＝AB 2，∴AC ⊥BC ．又BC ∩C 1C ＝C ，∴AC ⊥平面BCC 1B 1，而B 1C ⊂平面BCC 1B 1，∴AC ⊥B 1C ． （2）连接BC 1交B 1C 于O 点，连接OD ．如图，∵O ，D 分别为BC 1，AB 的中点，∴OD ∥AC 1．又OD ⊂平面CDB 1，AC 1⊄平面CDB 1．∴AC 1∥平面CDB 1． 19．【答案】（1）见解析；（2）存在，见解析．【解析】（1）证明∵P A ⊥底面ABC ，∴P A ⊥BC ．又∠BCA ＝90°，∴AC ⊥BC ． 又∵AC ∩P A ＝A ，∴BC ⊥平面P AC ．（2）∵DE ∥BC ，又由(1)知，BC ⊥平面P AC ，∴DE ⊥平面P AC ． 又∵AE ⊂平面P AC ，PE ⊂平面P AC ，∴DE ⊥AE ，DE ⊥PE ． ∴∠AEP 为二面角A DE P --的平面角． ∵P A ⊥底面ABC ，∴P A ⊥AC ，∴∠P AC ＝90°．∴在棱PC 上存在一点E ，使得AE ⊥PC ．这时∠AEP ＝90°， 故存在点E ，使得二面角A DE P --为直二面角．20．【答案】（1）见解析；（2． 【解析】（1）证明 连接BC 1，则O 为B 1C 与BC 1的交点．因为侧面BB 1C 1C 为菱形，所以B 1C ⊥BC 1．又AO ⊥平面BB 1C 1C ，所以B 1C ⊥AO ，故B 1C ⊥平面ABO ． 由于AB ⊂平面ABO ，故B 1C ⊥AB ．（2）解 在平面BB 1C 1C 内作OD ⊥BC ，垂足为D ，连接AD ． 在平面AOD 内作OH ⊥AD ，垂足为H ．由于BC ⊥AO ，BC ⊥OD ，故BC ⊥平面AOD ，所以OH ⊥BC ． 又OH ⊥AD ，所以OH ⊥平面ABC ．因为∠CBB 1＝60°，所以△CBB 1为等边三角形．又BC ＝1，可得OD =．由于AC ⊥AB 1，所以11122OA B C ==．由OH ·AD ＝OD ·OA，且AD =OH ．又O 为B 1C 的中点，所以点B 1到平面ABC， 故三棱柱111ABC A B C -． 21．【答案】（1）见解析；（2）见解析；（3）3P ABCD V -=． 【解析】（1）证明 连接OE ，如图所示．∵O 、E 分别为AC 、PC 的中点，∴OE ∥P A ． ∵OE ⊂面BDE ，P A

，∴EF ⊥BD ． ∵OF ⊥BD ，OF ∩EF ＝F ，∴BD ⊥面EFO ，∴OE ⊥BD ． ∴∠EOF 为二面角E BD C --的平面角，∴∠EOF ＝30°．在Rt △OEF中，1124OF OC AC ===，∴·tan 30EF OF =︒，∴2OP EF ==．∴2313P ABCD V a -=⨯． 22．【答案】（1）见解析；（2）见解析；（3）V =． 【解析】（1）证明在三棱柱111ABC A B C -中，BB 1⊥底面ABC ，所以BB 1⊥AB ． 又因为AB ⊥BC ，所以AB ⊥平面B 1BCC 1， 又AB ⊂平面ABE ，所以平面ABE ⊥平面B 1BCC 1． （2）证明 取AB 的中点G ，连接EG ，FG ．因为E ，F 分别是A 1C 1，BC 的中点，所以FG ∥AC ，且12FG AC =． 因为AC ∥A 1C 1，且AC ＝A 1C 1，所以FG ∥EC 1，且FG ＝EC 1， 所以四边形FGEC 1为平行四边形．所以C 1F ∥EG ．又因为EG ⊂平面ABE ，C 1F ⊄平面ABE ，所以C 1F ∥平面ABE ．（3）解 因为AA 1＝AC ＝2，BC ＝1，AB ⊥BC，所以AB == 所以三棱锥E －ABC的体积1111·12332ABC V S AA ==⨯⨯=△．。

Unit 3 单元测试一、阅读理解（共两节，满分35分）第一节（共10小题，每小题2.5分，满分25分）阅读下列短文，从每题所给的A、B、C和D四个选项中，选出最佳选项。
AMySpace, the social networking website, is different from other websites which only provide stories about other people. MySpace is a place that allows you to broadcast your own stories and personal information to as many people as you like. Started years ago, it is a big source of information for and about American kids.Teenagers and their parents feel very different about it. Teens are rushing to join the site, not sharing their parents’ worries. It signals yet another generation gap in the digital era.For teenagers, it is reliable network to keep in touch with their friends. They will often list their surnames, birthdays, after-school jobs, school clubs, hobbies and other personal information.“MySpace is an easy way to reach just about everyone. I don’t have all the phone numbers of my acquaintances. But if I want to get in touch with one of them, I could just leave them a message on MySpace,” said Abby Van Wassen. She is a 16-year-old student at Woodland Hills High of Pittsburgh, Pennsylvania.Parents on the other hand are seriously concerned about the security problems of MySpace. “Every time we hold a parents’ meeting, the first question is always about MySpace,” said Kent Gates, who travels the country doing Internet safety seminars（研讨会）.The National Centre for Missing and Exploited Children has received at least 288 MySpace related complaints, according to Mary Beth Buchanan, a lawyer in Pittsburgh.“Your profile on MySpace shows all your personal information to anyone on the Web. And MySpace even lists this information by birthplace and age. It’s like a free checklist for troublemakers and it endangers children,” Buchanan said.1. From the passage, we can learn that MySpace ________.A. brings about the generation gapB. is very careful about people’s privacyC. encourages you to list your personal informationD. lists the telephone numbers of your friends2. Why are some parents against MySpace?A. Because they think MySpace has a bad influence on their children.B. Because they don’t want to pay so much money for MySpace.C. Because it takes up too much of their children’s spare time.D. Because troublemakers can easily reach their children through the site.3. What can we infer from “Every time we hold a parents’ meeting, the first question is always about MySpace”?A. MySpace has become a top problem troubling parents.B. MySpace often holds parents meetings.C. MySpace is quite popular with parents.D. Parents have lots of questions about the website.BNetgear Wi-Fi Range ExtenderEst.

They are not loved by people because of their usage.CSuppose you’re in a rush, felling tired, not paying attention to your screen, and you send an email that could get you in trouble.Realisation will probably set in seconds after you’ve clicked “send”. You freeze in horror and bum with shame.What to do? Here are four common email accidents, and how to recover.Clicking “send” too soonDon’t waste your time trying to find out if the receiver has read it yet. Write another email as swiftly as you can and send it with a brief title explaining that this is the correct version and the previous version should be ignored.Writing the wrong nameThe sooner you notice, the better. Respond quickly and briefly, apologising for your mistake. Keep the tone measured: don’t handle it too lightly, as people can be offended, especially if your error suggests a misunderstanding of their culture （i. e. incorrect ordering of Chinese names）.Clicking “reply all” unintentionallyYou accidentally reveal（透露）to the entire company what menu choices you would prefer at the staff Christmas dinner, or what holiday you’d like to take. In this instance, the best solution is to send a quick, light-hearted apology to explain your awkwardness. But it can quickly rise to something worse, when everyone starts hitting “reply all” to join in a long and unpleasant conversation. In this instance, step away from your keyboard to allow everyone to calm down.Sending an offensive message to its subjectThe most awkward email mistake is usually committed in anger. You write an unkind message about someone, intending to send it to a friend, but accidentally send it to the person you’re discussing. In that case, ask to speak in person as soon as possible and say sorry. Explain your frustrations calmly and sensibly —see it as an opportunity to clear up any difficulties you may have with this person.7. After realizing an email accident, you are likely to feel ________.A. curiousB. tiredC. awfulD. funny8. If you have written the wrong name in an email, it is best to ________.A. apologise in a serious mannerB. tell the receiver to ignore the errorC. learn to write the name correctlyD. send a short notice to everyone9. What should you do when an unpleasant conversation is started by your “reply all” email?A. Try offering other choices.B. Avoid further involvement.C. Meet other staff members.D. Make a light hearted apology.10. What is the passage mainly about?A. Defining email errors.B. Reducing email mistakes.C. Handling email accidents.D. Improving email writing.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，选项中有两项为多余选项。
(人教版)英语单元测试【必修2】Unit 3(I)(含答案)(精修版)
人教版英语精品资料（精修版）Unit3单元检测踢I.听力部分.II.阅读理解.AArtist and cyclist-explorer (骑自行车探险家) Sima Gansai has just returned home in Birmingham after a 900-mile trip along the coast of Ireland on her bike. Sima Gansai learned more about Ireland from stories and recommendations (建议) from Irish friends in Birmingham and those she met on the way.The idea of having the trip was started by her Irish friends who always share their memories and stories about living in Ireland. She loved storytelling and decided to look for more and speak to members of the Irish Welfare Club. They marked all the places they came from on a map, which gave her the idea of cycling coast-to-coast in Ireland and see by herself where their stories came from.Starting from Dublin and finishing in Belfast during six weeks, she cycled 40 miles a day passing through many cities, towns and villages, asking local people where to travel next. Sima Gansai met many kind-hearted strangers. Her daily plan was to cycle 4 hours a day, find a place to stay, go out for some food and then visit the pubs to find stories. Pubs were like community centers and she found after a few hours people would be lining up to tell her their recommendations and stories. Sima Gansai said, “I filmed as much of the journey as I could.” Sima Gansai’s exploration will now be written into a book and made into a film about the special side of Ireland. You can see more of her journey on her Myspace page.21. We can learn the following from the first paragraph EXCEPT ________.A. where Sima Gansai livedB. how Sima Gansai traveled in IrelandC. how long Sima Gansai’s journey wasD. when Sima Gansai finished her travel22. Why did Sima Gansai start her coast-to-coast trip in Ireland?A. To make much of her journey into film.B. To meet more kind-hearted Irish people.C. To collect more stories about Ireland.D. To share her exploration with readers.23. Whom does the underlined word “they” refer to in the second parag raph?A. Kind-hearted strangers.B. Sima Gansai’s family members.C. Sima Gansai’s Irish friends.D. Irish strangers.24. We are told in the passage that __________.A. it was the first time that Sima Gansai cycled to travelB. Sima Gansai started her journey in Belfast, IrelandC. Sima Gansai’s friends visited Ireland with her togetherD. many Irish people waited to tell Sima Gansai stories25. What did Sima Gansai do during her journey?A. She lined up to listen to stories.B. She made a map of Ireland.C. She cycled 40 miles a day.D. She wrote a book about her exploration.BAs the world is getting faster and technology develops day by day, computer users feel it necessary to have a computer that is as powerful as a desktop computer and which can be carried easily. So, a new form of computer has arrived, which is known as laptop.Laptops, which can be easily carried, are as powerful as desktop computers, but come with a highly-sophisticated (精密的) design and are light weight. They are sometimes called notebook computers. They run on a single battery or from an AC/DC adaptor that charges the battery while supplying power to the computer itself. Laptops all have the same configurations (配置) as desktop computers apart from the cabinet and the screen. They usually have LCD displays and most of them use different memory modules (内存模块) for their Random Access Memory (随机存储器). Laptops are different in configurations, shapes, designs and prices. There are some companies that produce cheap laptops. Cheap laptops are offering improved features that can be used for both business and personal purposes like e-mailing, downloading files, etc. There are various laptop brands like Dell and Toshiba which produce cheap laptops.There are companies like Apple, HP and Acer which are famous for their high quality laptops. The breakthrough (突破) came when Apple Inc. introduced the Apple MacBook Pro. These are extremely good laptops with outstanding speed, and highly fashionable looks. On the other side, in Windows, laptop HP Pavilion is one of the best-selling brands. You can turn to page 96 to get more information about laptops.26. According to the first paragraph, the following are all driving forces (推动力) in the appearance of laptops EXCEPT ________.A. the fast development of the worldB. the ever-improving technologyC. the powerlessness of desktop computersD. people’s needs for more convenient computers2.7 Paragraph 2 mainly talks about ________.A. what a laptop looks likeB. laptops’ featuresC. the configurations of laptopsD. the production of laptops28. If someone wants to buy a cheap laptop, he may turn to ________.A. AppleB. HPC. ToshibaD. Acer29. Why does the author say the introduction of Apple MacBook Pro is a breakthrough?A.
