高中语文必修二综合能力测试一、现代文阅读(9分)阅读下面的文字,完成1~3题。

“年度流行语”也是我们生活的一部分苑广阔“且行且珍惜”“你家里人知道吗?”“萌萌哒”“有钱就是任性”……当2014 年进入倒计时的时候,媒体对这些曾经风靡一时的网络流行语的盘点,既带给人们一种亲切感,同时又让人感觉有点淡淡的忧伤,毕竟在这些网络流行语当中,有相当一部分寿命都很短暂,随着新的一年到来,它们就会被新的网络流行语所代替,提醒着我们又一年的悄然逝去。

每一句网络流行语的背后,都往往代表着一起事件,也代表着一种情绪,所以我们可以把其看作是对过去一年的一种另类总结。

虽然网友们在网络和现实中使用这些网络流行语的时候,多数以调侃、自嘲为目的,但实际上这些流行语的背后,也同样有值得我们汲取的有营养价值的东西。

比如因为影视明星文章的“出轨门”而催生出的网络流行语“且行且珍惜”,就是一句本身充满人生哲理的话。

这虽然是文章的爱人,另外一位影视明星马伊琍规劝自己丈夫浪子回头的话,但应该被规劝的,何止是文章一个人呢?对任何人来说,都是“恋爱虽易,婚姻不易”,所以任何人都要“且行且珍惜”。

明星们的绯闻轶事不过是因为他们明星的身份而被无限放大了而已,但是普通人的婚外恋、婚外情等等,也同样会对婚姻的另一半和家庭、亲人带来莫大的伤害,让自己的生活变得一地鸡毛。

所以面对“且行且珍惜”这样的网络流行语,值得我们每个人反躬自省,其背后的教训也值得我们每个人汲取,进而增加自己对爱情、对婚姻、对家庭的责任感。

再比如年底才开始流行的“有钱就是任性”。

其背后代表的事件是宁波市一位老人遭遇了电信诈骗,先后被骗取了几十万元,而当记者采访老刘时,老刘却说:被骗7 万的时候发现上当了,当时觉得警察不会管,又想看他们究竟能骗多少钱。

这则新闻引爆互联网,网友调侃:有钱就这么任性。

而眼下正是各种类型的网络诈骗高发频发的时候,“有钱就是任性”恰恰是对我们的一种警示,提醒我们增强防范意识和自我保护意识。

人教版必修二第四单元第12课 从计划经济到市场经济 练习试题(含答案解析)

人教版必修二第四单元第12课 从计划经济到市场经济 练习试题(含答案解析)

第12课从计划经济到市场经济一、单选题1.1992年1月18日至2月21日,邓小平多次提到,“改革开放胆子要大一些,敢于试验,不能像小脚女人一样。

看准了的,就大胆地试,大胆地闯。

深圳的重要经验就是敢闯。

”这一思想对中国的改革开放产生了重大影响。

当时的中国A. 已经明确了邓小平理论的指导地位B. 正处于改革开放新的探索时期C. 确立了社会主义市场经济体制的目标D. 开始确立实事求是的思想路线【答案】B【解析】本题主要考查新时期经济改革的相关知识,旨在考查运用所学知识解读材料信息的能力。

邓小平理论的指导地位确立是1997年中共十五大,故A项错误;题干所述为邓小平的南巡讲话,而确立了社会主义市场经济体制的目标是中共十四大,排除C 项;D项“开始”表述不符合史实,排除;1992年,邓小平南巡讲话,指出标志着中国改革进入新的阶段。

故选B。

2.1983年,国家有关部门指出,去年国有企业首钢创利润4.1亿,交国家2.862亿元后,在当年新增利润中拿的太多。

首钢领导则认为,企业去年上交利润又递增了6%,不应该“只知取蛋,不想养鸡”。

材料说明当时的城市经济体制改革急需()A. 政企分开,建立企业承包责任制B. 简政放权,扩大企业的自主权C. 搞活企业,发展多种所有制经济D. 释放活力,取消计划管理体制【答案】B【解析】从材料中“首钢领导则认为,不应该“只知取蛋,不想养鸡”说明企业想简政放权,扩大企业自主权,故B正确,ACD不符合题意。

故选B。

本题考查中国经济体制改革。

本题考查学生解读史料获取信息的能力,解答关键是对材料“只知取蛋,不想养鸡”准确解读,并对改革开放以来的国有企业的改革的相关内容准确解读。

我国城市经济体制改革主要内容:(1)管理体制:实行政企分开,简政放权,使企业成为自主经营、自负盈亏的社会主义商品生产者和经营者。

(2)所有制:变单一的公有制经济为以公有制经济为主体、多种所有制经济共同发展。

(3)分配制度:实行以按劳分配为主、多种分配方式并存的分配制度。

Yep, it really is that good.Set in a world populated by robots, Ewan McGregor plays Rodney Copperbottom, a young robot who leaves his small-town home to pursue his dream of becoming an inventor.But after arriving in Robot City, his hopes of getting a job at Bigweld Industries are destroyed when he learns the firm has been taken over by the evil Ratchet (Greg Kinnear).Egged on by his controlling mum, Madame Gasket (Jim Broadbent), Ratchet plans to reduce half of Robot City’s citizens to scrap metal by refusing to sell the spare parts they need to survive.Ins tead, he wants to make a fortune selling expensive upgrades that few can afford. As he says, “Why be you when you can be new?〞Aided by a few misfit robots known as the Rustles—including Robin Williams as the cowardly' (胆小的〕Fender (“I’m made of a metal cal led Afraidium〞)—Rodney must track down the firm’s founder, Bigweld (Mel Brooks), and convince him to save the city from Ratchet’s plans.The first thing that’ll strike you about the movie is the thought that's gone into creating Robot City. It’s a wondrous world full of mechanical marvels including wind-up cars and walking streetlamps.Also terrific are the special effects. This might be an animated movie but at times you’ll catch yourself thinking it’s really a live-action film.Of course, there have been plenty of animated movies that looked the part but were let down by a weak storyline (see Shark Tale, for example).But Robots grips (扣人心弦) right from the start thanks to a heart-warming and thoroughly engaging plot that never bores.My only complaints are with Williams who, as usual,has a one-in-10 success rate with his jokes. Also a letdown is a romantic subplot between Rodney and a shapely robot called Cappy (Halle Berry) that doesn’t go anywhere.Complains aside, this is a mechanical marvel that’ll have you bolted firmly to your seat.BEST QUOTE(引述): Fender: “Even though you had a discouraging day, just remember there’s another one coming tomorrow.〞BEST BIT: Check out those amazing images.WORST BIT: Robin Williams, character does an unfunny Britney Spears dance routine.IF YOU LIKED…Ice Age, The Incredibles, Toy Story... YOU’LL LIKE THIS.【小题1】This piece of writing is a _______.A. commercial advertisementB. film reviewC. movie posterD. literary essay【小题2】The cast of Robots is made up of all the following actors or actresses EXCEPT _______.A. Ewan McGregorB. Robin WilliamsC. Britney SpearsD. Halle Berry【小题3】What is Shark Tale an example of?A. A great cast.B. A poor plot.C. Special effects.D. Clumsy animation.B.These young men were a different kind of prisoner from those we had seen before. They-were brave, hostile〔怀敌意的〕and_1__ they would not take orders, and shouted"Amandla!〞at every opportunity. Their instinct was to confront〔对抗〕rather than cooperate. The authorities② did not know how to handle them, and they turned theisland upside down. During the Rivonia Trial, I remarked to a security policeman that if the government did not reform itself, the freedom fighters who would take our place③would some-day make theauthorities miss us. That day had indeed come on Robben Island.In these young men we saw the angry revolutionary spirit of the times. I had had some warning. On a visit with Winnie a few months before, she had managed to tell me through our coded conversation that there was a rising class of discontented youths④ who were violent and Africanist in beliefs. She said they were changing the nature of the struggle and that I should be aware of them.The new prisoners were shocked by what they considered the inhuman conditions of the island, and said that they could not understand how we could live in such a way. We told them that they should have seen the island in 1964. But they were almost as sceptical of us as they were of the authorities. They chose to ignore our calls for discipline and thought our advice weak and unassertive〔不果断〕.It was obvious that they regarded us, the Rivonia Trialists⑤,as moderates⑥〔温和派〕.After so many years of being branded a radical〔激进的〕revolutionary, to be seen as a moderate was a novel and not altogether pleasant feeling. I knew that I could react in one of two ways:I could scold them for their disrespect or I could listen to what they were saying. I chose the latter.'then some of these men, such as Strini Moodley of the South African Students' Organization and Saths Cooper of the Black People's Convention, came into our section, I __2____ Shortly after their arrival on the island, the commanding officer came and asked me as a favour to address the young men. He wanted me to tell them to behave themselves, to recognize the fact that they were in prison and to accept the discipline of prison life.I told him that I was not prepared to do that.

Extra!Gasoline hits four dollars a gallon!〞No one will really be shocked一except, perhaps, the old-timers who tell about the good old days when gas was three gallons for a dollar, and people drove around "just for the fun of it".As a matter of fact; the price of gas has been rising fast and steadily for several years, and many adjustments have already been made.There was, for a time, considerable unemployment in the auto industry, and three quarters of the garages and service stations have gone out of business. However; the bicycle andmotor-scooter business has flourished〔兴隆); and many people have found employment there: Now that Federal Motors has brought out its new Lilliput, which travels forty miles on a gallon, the auto business is picking up again. The factories that haven't switched over to two-wheel transportation are working on their new smaller models. There is talk, too, about bringing out new steam and electric automobiles that will be just as economical as the old cars.In the meantime, streetcars are gradually replacing buses all over the country because of the greater economy of electric power. And many people who have seldom used public transportation are now riding the streetcars while their automobiles rust〔生锈〕in their garages. There's no market at all for their big, luxurious cars, for only the wealthy can now afford to operate them. Many people are now shopping in their own neighborhood, and small businesses are thriving.Ministers, educators, and editorial writers are pointing out that there has been a great improvement in family life. Families now stay at home more for their fun, and children and parents are becoming better acquainted. The stores report a booming business in parlor games, hobby materials, books, musical instruments and albums.People have lost their pale indoor look. The revival of the lost art of walking has brought a healthy pink back to many a cheek. This return to the heels has revolutionized the clothing styles; people now need to be ready for all kinds of weather:These conditions, however, may not last. Already our clever chemists are at work on new synthetic fuels which, they say, will put us right back where we were一on wheels. Shall w e wish them success or not?【小题1】Which of the following is NOT a result of the gas price rising?A. More people prefer to travel on public transportation which costs less than driving cars.B. People return to the traditional exercise of walking, which helps them to look healthier.C. People shop in nearby stores without having to drive, so small businesses are declining.D. The auto industry has been forced to develop new models which are more economical. 【小题2】The purpose of writing this passage is_.A. to show the chain reaction of the rising gas priceB. to discuss whether it's necessary to work on new fuelsC. to warn people not to use too much gasolineD. to picture what life will be like if gas runs out【小题3】What is the best title for this passage?A. New fuels on the wayB. Cars or bicycles, that is a questionC. End of the good old daysD. From wheels to heelsDRecently, an almost literal case of lifeboat ethics(伦理) occurred. On Aug. 4, Graham and Sheryl Anley, while boating off the coast of South Africa, hit a rock. As the boat threatened to sink the husband got off, but his wife was trapped in the boat. Instead of freeing his wife and getting her to shore, Graham grabbed Rosie, their pet dog. With Rosie safe and sound, Graham returned for Sheryl. All are doing fine.It's a great story, but it doesn't strike me as especially newsworthy. News is supposed to be about something fairly unique, and recent research suggests that, in the right circumstances, lots of people also would have grabbed their Rosie first.We have strange relationships with our pets. We lavish our pets with adoration and better health care thanbillions of people receive. We speak to pets with the same high-pitched voices that we use for babies. As an extreme example of our feelings about pets, the Nazis had strict laws that guaranteed the humane treatment of the pets of Jews being shipped to death camps.A recent paper by George Regents University demonstrates this human involvement with pets to an astonishing extent. Participants in the study were told a situation in which a bus is out of control, bearing down on a dog and a human. Which do you save? With responses from more than 500 people, the answer was that it depended: What kind of human and what kind of dog?Everyone would save a brother, grandparent or close friend rather than a strange dog. But when people considered their own dog versus people less connected with them—a distant cousin or a hometown stranger—votes in favor of saving the dog came rolling in. And an astonishing 40% of respondents, including 46% of women, voted to save their dog over a foreign tourist.What does a finding like this mean? First, that your odds aren't so good if you find yourself in another country with a bus bearing down on you and a cute dog. But it also points to something deeper: our unprecedented(史无前例的) attitude toward animals, which got its start with the birth of humane societies in the 19th century.We prison people who abuse animals, put ourselves in harm's way in boats between whales and whalers and show sympathy to Bambi and his mother. We can extend empathy to an animal and feel its pain like no other species. But let's not be too proud of ourselves. As this study and too much of our history show, we're pretty selective about how we extend our humaneness to other human beings.【小题1】What is the function of the first paragraph?A. To create a relaxing mood for readers.B. To present the theme of this essay straightly.C. To lead in the main topic of this essay.D. To raise problems that will be solved later.【小题2】The author mentions Nazi laws in the third paragraph _______________.A. to show how cruel the Nazis were to the JewsB. as an example to persuade people not to love petsC. to illustrate the strange relationship between human and petsD. as an example to display the humaneness of the Nazis【小题3】Which of the following is true according to the article?A. The story of the Anleys and their dog was too unique to be newsworthy.B. Most people surveyed choose to save their own dog rather than a human.C. It was in the 19th century that human beings started to love their pets.D. Human beings are more and more concerned with animals nowadays.【小题4】What does the author mainly argue for?A. Pets are of great significance to us human beings.B. We should rethink about our attitude towards animals and mankind.C. It is kind of human beings to extend humaneness to animals.D. We should be selective when showing attitude toward other human beings.四季寄语情感寄语在纷繁的人群中/牵手走过岁月/就像走过夏季/拥挤的海滩在我居住的江南/已是春暖花开季节/采几片云彩/轻捧一掬清泉/飘送几片绿叶/用我的心/盛着寄给/北国的你不要想摆脱冬季/看/冰雪覆盖的世界/美好的这样完整/如我对你的祝福/完整地这样美好挡也挡不住的春意/像挡也挡不住的/想你的心情/它总在杨柳枝头/泄露我的秘密往事的怀念/爬上琴弦/化作绵绵秋雨/零零落落我诚挚的情怀/如夏日老树下的绿荫/斑斑驳驳虽只是一个小小的祝福/却化做了/夏季夜空/万点星辰中的一颗对你的思念/温暖了/我这些个漫长的/冬日从春到夏,从秋到冬......只要你的帘轻动,就是我的思念在你窗上走过.在那个无花果成熟的季节,我才真正领悟了你不能表达的缄默.我又错过了一个花期/只要你知道无花也是春天/我是你三月芳草地燕子声声里,相思又一年朋友,愿你心中,没有秋寒.一到冬天,就想起/那年我们一起去吃的糖葫芦/那味道又酸又甜/就像......爱情.谢谢你/在我孤独时刻/拜访我这冬日陋室只要有个窗子/就拥有了四季/拥有了世界愿你:俏丽如三春之桃,清素若九秋之菊没有你在身边,我的生活永远是冬天!让我们穿越秋天/一起去领略那收获的喜悦!在冬天里,心中要装着春天;而在春天,却不能忘记冬天的寒冷.落红不是无情物,化作春泥更护花.愿是只燕,衔着春光,翩翩向你窗.请紧紧把握现在/让我们把一种期翼/或者是一种愿望/种进大地/明春/它就会萌生绿色的叶片.此刻又是久违的秋季/又是你钟爱的季节/于是/秋风秋雨秋云秋月/都化作你的笑颜身影/在我的心底落落起起.此刻已是秋季/你可体验到/收获怀念的感觉/和秋雨一样真实动人.一条柳枝/愿是你生活的主题/常绿常新/在每一个春季雨声蝉鸣叶落风啸/又一个匆匆四季/在这冬末春初/向遥远的你/问安!又是夏季/时常有暴雨雷鸣/此刻/你可以把我当作大雨伞/直至雨过天晴/留给你一个/彩虹的夏季!。

C[解析]AB与CC1为异面直线,故棱中不存在同时与两者平行的直线,因此只有两类:第一类与AB平行与CC1相交的有:CD、C1D1与CC1平行且与AB相交的有:BB1、AA1,第二类与两者都相交的只有BC,故共有5条.2.室内有一直尺,无论怎样放置,在地面上总有这样的直线,它与直尺所在的直线( )A.异面B.相交C.平行D.垂直[答案] D[解析]当直尺与地面垂直时,地面上的任意一条直线都和直尺所在的直线垂直;当直尺所在的直线与地面不垂直时,过直尺所在的直线作一与地面垂直的平面,此平面与地面的交线设为a,则地面内任一与交线a垂直的直线都与直尺所在的直线垂直.3.如图所示,过正方体ABCD-A1B1C1D1的顶点A作直线l,使l 与棱AB,AD,AA1所成的角都相等,这样的直线l可以作( )A.1条B.2条C.3条D.4条[答案] D[解析]连接AC1,则AC1与棱AB,AD,AA1所成的角都相等;过点A分别作正方体的另外三条体对角线的平行线,则它们与棱AB,AD,AA1所在的角也相等,故这样的直线l可以作4条.4.设P是△ABC所在平面α外一点,H是P在α内的射影,且PA,PB,PC与α所成的角相等,则H是△ABC的( )A.内心B.外心C.垂心D.重心[答案] B[解析]由题意知Rt△PHA≌Rt△PHB≌Rt△PHC,得HA=HB=HC,所以H是△ABC的外接圆圆心.5.已知二面角α-l-β的大小为60°,m,n为异面直线,且m ⊥α,n⊥β,则m,n所成的角为( )A.30°B.60°C.90°D.120°[答案] B[解析]易知m,n所成的角与二面角的大小相等,故选B.6.下面四个命题:①若直线a,b异面,b,c异面,则a,c异面;②若直线a,b相交,b,c相交,则a,c相交;③若a∥b,则a,b与c所成的角相等;④若a⊥b,b⊥c,则a∥c.其中真命题的个数为( )A.4 B.3C.2 D.1[答案] D[解析]异面、相交关系在空间中不能传递,故①②错;根据等角定理,可知③正确;对于④,在平面内,a∥c,而在空间中,a与c 可以平行,可以相交,也可以异面,故④错误.7.在正方体ABCD-A1B1C1D1中,E,F分别是线段A1B1,B1C1上的不与端点重合的动点,如果A1E=B1F,有下面四个结论:①EF⊥AA1;②EF∥AC;③EF与AC异面;④EF∥平面ABCD.其中一定正确的有( )A.①②B.②③C.②④D.①④[答案] D[解析]如图所示.由于AA1⊥平面A1B1C1D1,EF⊂平面A1B1C1D1,则EF⊥AA1,所以①正确;当E,F分别是线段A1B1,B1C1的中点时,EF ∥A1C1,又AC∥A1C1,则EF∥AC,所以③不正确;当E,F分别不是线段A1B1,B1C1的中点时,EF与AC异面,所以②不正确;由于平面A1B1C1D1∥平面ABCD,EF⊂平面A1B1C1D1,所以EF∥平面ABCD,所以④正确.8.设a,b为两条不重合的直线,α,β为两个不重合的平面,下列命题中为真命题的是( )A.若a,b与α所成的角相等,则a∥bB.若a∥α,b∥β,α∥β,则a∥bC.若a⊂α,b⊂β,a∥b,则α∥βD.若a⊥α,b⊥β,α⊥β,则a⊥b[答案] D[解析] 选项A 中,a ,b 还可能相交或异面,所以A 是假命题;选项B 中,a ,b 还可能相交或异面,所以B 是假命题;选项C 中,α,β还可能相交,所以C 是假命题;选项D 中,由于a ⊥α,α⊥β,则a ∥β或a ⊂β,则β内存在直线l ∥a ,又b ⊥β,则b ⊥l ,所以a ⊥b .9.(2012·大纲版数学(文科))已知正方体ABCD -A 1B 1C 1D 1中,E 、F 分别为BB 1、CC 1的中点,那么直线AE 与D 1F 所成角的余弦值为( )A .-45D.35 C.34D .-35[命题意图] 本试题考查了正方体中异面直线的所成角的求解的运用.[答案] D[解析]

本题可以根据面面平行和面面垂直的判定定理和性质定理,寻找使结论成立的充分条件.[证明](1)在正三棱柱ABC-A1B1C1中,∵F、F1分别是AC、A1C1的中点,∴B1F1∥BF,AF1∥C1F.又∵B1F1∩AF1=F1,C1F∩BF=F,∴平面AB1F1∥平面C1BF.(2)在三棱柱ABC-A1B1C1中,AA1⊥平面A1B1C1,∴B1F1⊥AA1.又B1F1⊥A1C1,A1C1∩AA1=A1,∴B1F1⊥平面ACC1A1,而B1F1⊂平面AB1F1,∴平面AB1F1⊥平面ACC1A1.18.(本小题满分12分)如下图所示,在四棱锥P-ABCD中,PA ⊥平面ABCD,AB=4,BC=3,AD=5,∠DAB=∠ABC=90°,E是CD 的中点.(1)证明:CD⊥平面PAE;(2)若直线PB与平面PAE所成的角和PB与平面ABCD所成的角相等,求四棱锥P-ABCD的体积.[解析](1)如下图所示,连接AC,由AB=4,BC=3,∠ABC=90°,得AC=5.又AD=5,E是CD的中点,所以CD⊥AE.∵PA⊥平面ABCD,CD⊂平面ABCD,所以PA⊥CD.而PA,AE是平面PAE内的两条相交直线,所以CD⊥平面PAE.(2)过点B作BG∥CD,分别与AE,AD相交于F,G,连接PF.由(1)CD ⊥平面PAE 知,BG ⊥平面PAE .于是∠BPF 为直线PB 与平面PAE 所成的角,且BG ⊥AE .由PA ⊥平面ABCD 知,∠PBA 为直线PB 与平面ABCD 所成的角.AB =4,AG =2,BG ⊥AF ,由题意,知∠PBA =∠BPF ,因为sin ∠PBA =PA PB ,sin ∠BPF =BFPB,所以PA =BF . 由∠DAB =∠ABC =90°知,AD ∥BC ,又BG ∥CD ,所以四边形BCDG 是平行四边形,故GD =BC =3.于是AG =2.在Rt △BAG 中,AB =4,AG =2,BG ⊥AF ,所以BG =AB 2+AG 2=25,BF =AB 2BG =1625=855.于是PA =BF =855.又梯形ABCD 的面积为S =12×(5+3)×4=16,所以四棱锥P -ABCD的体积为V =13×S ×PA =13×16×855=128515. 19.(本小题满分12分)如图所示,边长为2的等边△PCD 所在的平面垂直于矩形ABCD 所在的平面,BC =22,M 为BC 的中点.(1)证明:AM⊥PM;(2)求二面角P-AM-D的大小.[解析](1)证明:如图所示,取CD的中点E,连接PE,EM,EA,∵△PCD为正三角形,∴PE⊥CD,PE=PD sin∠PDE=2sin60°= 3.∵平面PCD⊥平面ABCD,∴PE⊥平面ABCD,而AM⊂平面ABCD,∴PE⊥AM.∵四边形ABCD是矩形,∴△ADE,△ECM,△ABM均为直角三角形,由勾股定理可求得EM =3,AM=6,AE=3,∴EM2+AM2=AE2.∴AM⊥EM.又PE∩EM=E,∴AM⊥平面PEM,∴AM⊥PM.(2)解:由(1)可知EM⊥AM,PM⊥AM,∴∠PME是二面角P-AM-D的平面角.∴tan∠PME=PEEM=33=1,∴∠PME=45°.∴二面角P-AM-D的大小为45°.20.(本小题满分12分)如图,几何体E-ABCD是四棱锥,△ABD 为正三角形,CB=CD,EC⊥BD.(1)求证:BE=DE;(2)若∠BCD=120°,M为线段AE的中点,求证:DM∥平面BEC.[解析](1)设BD中点为O,连接OC,OE,如图,则由BC=CD 知,CO⊥BD,又已知CE⊥BD,所以BD⊥平面OCE.所以BD⊥OE,即OE是BD的垂直平分线,所以BE=DE.(2)取AB中点N,连接MN,DN,∵M是AE的中点,∴MN∥BE,∵△ABD是等边三角形,∴DN⊥AB.由∠BCD=120°知,∠CBD=30°,所以∠ABC=60°+30°=90°,即BC⊥AB,所以ND∥BC,所以平面MND∥平面BEC,故DM∥平面BEC.21.(本小题满分12分)如图,棱柱ABC-A1B1C1的侧面BCC1B1是菱形,B1C⊥A1B.(1)证明:平面AB1C⊥平面A1BC1;(2)设D是A1C1上的点,且A1B∥平面B1CD,求A1D DC1的值.[解析](1)因为侧面BCC1B1是菱形,所以B1C⊥BC1,又已知B1C⊥A1B,且A1B∩BC1=B,所以B1C⊥平面A1BC1,又B1C⊂平面AB1C,所以平面AB1C⊥平面A1BC1 .(2)设BC1交B1C于点E,连接DE,则DE是平面A1BC1与平面B1CD 的交线.因为A1B∥平面B1CD,A1B⊂平面A1BC1,平面A1BC1∩平面B1CD=DE,所以A1B∥DE.又E是BC1的中点,所以D为A1C1的中点.即A1D DC1=1.22.(本小题满分12分)(2013·全国新课标卷Ⅰ)如图三棱柱ABC
