2009年广东高考英语试题及答案(A卷)

2009高考广东卷英语答案解析及试卷分析第一节听力理解（略）21-30、答案与解析本文记叙了阿尔佛雷德?诺贝尔决定设立诺贝尔奖金的经过。

21. C。

因mistake A for B (将A误以为B)是固定搭配。

22. B。

由常识可知，报社应是“发布”消息，故用announce (give information about)。

23. C。

由首句became a millionaire可知。

24. A。

根据常识，看到自己本来死却报道死了这样的消息，特别是说自己通过kill more people faster来发财的评论，应当是“不高兴，苦恼(unhappy or annoyed)”，不可能是“兴奋的(excited)”“高兴的(pleased)”“渴望的(anxious)”。

25. D。

与destruction(毁灭)并列的应是attack(攻击)，上文的warfare (战争), kill more people 也都说明要选D。

再说，根据有关dynamite (炸药)的特点与运用的常识也可选出正确答案。

26. D。

由后文设立奖金可知，是为了改变自我形象，要设法“被别人充满爱与尊敬地铭记(be remember with love and respect)”。

27. C。

由最后一句Nobel had to die before he realized…可知，是在“遗嘱(will)”中作的安排。

28. A。

根据与名词the Nobel prizes的搭配，又结合常识，应当是“设立”诺贝尔奖金。

29. D。

奖金应当是将给那些为世界和平、文学和科学等领域作出过巨大贡献的人。

make contributions to…(对……作出贡献)是固定搭配。

30. A。

遗嘱中安排设立奖金，因此，“普遍(by or to most people, widely)”认为，他到死时才意识到他的人生的真正意义。

分析与点评：本大题中由理解空格所在句本身即可选出答案的有21(固定搭配)题，22题(常识)，24题(常识)，26题(固定搭配与常识)，28题(动宾搭配与常识)，29题(固定搭配)等6道题，占总数的60%。

(1) 证明：PC ⊥平面PAB ；(2) 求二面角P －AB －C 的平面角的余弦值；(3) 若点P 、A 、B 、C 在一个表面积为12π的球面上，求△ABC 的边长.解 (1) 连结CF ，∵PE ＝EF ＝21BC ＝21AC ∴AP ⊥PC ∵CF ⊥AB, PF ⊥AB, ∴AB ⊥平面PCF ∵AC ⊂平面PCF ∴PC ⊥AB ∴PC ⊥平面PAB. (2) ∵AB ⊥PF, AB ⊥CF ∴∠PFC 为所求二面角的平面角 设AB ＝a, 则PF ＝EF ＝2a , CF ＝a3,∴cos ∠PFC ＝33232=a a.(3) 设PA ＝x, 球半径为R ∵PC ⊥平面PAB ，PA ⊥PB ∵4πR 2＝12π, ∴R ＝3, 知△ ABC 的外接圆为球之小圆，由x 2＝33x·2R. 得△ABC 的边长为22.1．因为“球”是“圆”在空间概念上的延伸，所以研究球的性质时，应注意与圆的性质类比． 2．球的轴截面是大圆，它含有球的全部元素，所以有关球的计算，可作出球的一个大圆，化“球”为“圆”来解决问题．3．球心与小圆圆心的连线，垂直于小圆所在的平面，球的内部结构的计算也由此展开． 4．计算球面上A 、B 两点的球面距离是一个难点，其关键是利用“AB 既是小圆的弦，又是大圆的弦”这一事实，其一般步骤是：(1) 根据已知条件求出小圆的半径r 和大圆的半径R ，以及所对小圆圆心角； (2) 在小圆中，由r 和圆心角求出AB ； (3) 在大圆中，由AB 和R 求出大圆的圆心角；(4) 由圆心角和R ，求出大圆弧长AB (即球面上A 、B 两点的距离)． ●闯关训练 夯实基础1.已知球O 的半径为1，A 、B 、C 三点都在球面上，且每两点间的球面距离均为2π，则球心O 到平面ABC 的距离为A.31 B. 33 C. 32D. 36解析：显然OA 、OB 、OC 两两垂直，如图，设O 1为ABC 所在平面截球所得圆的圆心，C∵OA =OB =OC =1，且OA ⊥OB ⊥OC ， ∴AB =BC =CA =2.∴O 1为△ABC 的中心.∴O 1A =36. 由OO 12＋O 1A 2=OA 2，可得OO 1=33.答案：B2.已知过球面上A 、B 、C 三点的截面和球心的距离等于球半径的一半，且AB =BC =CA =2，则球面面积是A.9π16B.3π8C.4πD.9π64解析：因为AB =BC =CA =2，所以△ABC 的外接圆半径为r =332.设球半径为R ，则R 2－（21R ）2=34，所以R 2=916，S =4πR 2=9π64. 答案：D3.已知球内接正方体的表面积为S ，那么球的体积等于_____________.解析：易知球直径2R 等于正方体的对角线长3a ，由6a 2=S ，得a =6S ，所以V 球=3π4R 3= 3π4（23a ）3=3π4（23·6S ）3=S S 224π.答案：S S224π 4.有两个半径都是r 的球，其中一个球的球心在另一个球的球面上，则这两个球的交线长为_____________.解析：由题意易得交线为半径为23r 的圆周，其长为3πr . 答案：3πr5.把地球看作半径为R 的球，A 、B 是北纬30°圈上的两点，它们的经度差为60°，求A 、B 两点间的球面距离.解：如图，设30°纬度圈的圆心为O 1，半径为r ，则r =R cos30°.依题意∠AO 1B =60°，取AB 的中点C ，则BC =R cos30°sin30°=43R ， 在Rt △BOC 中，sin ∠BOC =sin21∠AOB =RBC =43，∴∠AOB =2arcsin43，从而A 、B 两点的球面距离为2R arcsin 43..6.如图，三棱锥V—ABC中，VA⊥底面ABC，∠ABC=90°（1）求证：V、A、B、C四点在同一球面上；（2）过球心作一平面与底面内直线AB垂直，求证：此平面截三棱锥所得的截面是矩形.证明：（1）取VC的中点M，∵VA⊥底面ABC，∠ABC=90°，∴BC⊥V B.在Rt△VBC中，M为斜边VC的中点，∴MB=MC=MV.同理，在Rt△VAC中，MA=MV=MC.∴MV=MC=MA=MB.∴V、A、B、C四点在同一圆面上，M是球心.（2）取AC、AB、VB的中点分别为N、P、Q，连结NP、PQ、QM、MN，则MNPQ 就是垂直于AB的三棱锥V—ABC的截面，易证PQMN是平行四边形.又VA⊥BC，QP∥VA，NP∥BC，∴QP⊥PN.故截面MNPQ是矩形.培养能力7.已知球面上的三点A、B、C，AB=6，BC=8，AC=10，球的半径为13，求球心到平面ABC的距离.解：∵62+82=102，∴△ABC为Rt△.∵球心O在平面ABC内的射影M是截面圆的圆心，∴M是AC的中点且OM⊥AC.在Rt △OAM 中，OM =22AM OA -=12.∴球心到平面ABC 的距离为12.8.（文）将半径为R 的四个球，两两相切的放在桌面上，求上面一个球的球心与桌面的距离.解：如下图，作OH ⊥面O 1O 2O 3，O 2∵O 3H =332 R ， ∴OH =2323H O OO -=362 R ，球心与桌面的距离为（362 +1）R . （理）设A 、B 、C 是半径为1的球面上的三点，B 、C 两点间的球面距离为3π，点A 与B 、C 两点间的球面距离均为2π，O 为球心，求： （1）∠AOB 、∠BOC 的大小； （2）球心O 到截面ABC 的距离.解：如图，（1）因为球O 的半径为1，B 、C 两点间的球面距离为3π，点A 与B 、C 两点间的球面距离均为2π，所以∠BOC =3π，∠AOB =∠AOC =2π.（2）因为BC =1，AC =AB =2，所以由余弦定理得cos ∠BAC =43，sin ∠BAC =47，设截面圆的圆心为O 1，连结AO 1，则截面圆的半径R =AO 1，由正弦定理得r =BACBC∠sin 2=772，所以OO 1=22r OA -=721.9.在一个轴截面是正三角形的圆锥形容器中注入高为h 的水，然后将一个铁球放入这个圆锥形的容器中，若水面恰好和球面相切，求这个铁球的半径.解：如图，作出圆锥形容器的轴截面，△ABS 为等边三角形.A B S∵SG =h ，DG =33h ，∴V 水=3π·DG 2·SG =9πh 3. 设铁球的半径为R ， 则SO =2R ，SF =3R ，在Rt △FSB 中 ，BF =SF tan ∠FSB =3R ， 设放入球之后，球与水共占体积为V ′，则V ′=3π·（BF ）2·SF =3π（3R ）2·3R =3πR 3，V 球=3π4 R 3.依题意，有V ′=V 球+V 水，即3πR 3=3π4 R 3+9πh 3，∴R =152253h .答：铁球的半径为152253h .●思悟小结1.球的面积、体积及基本性质是解决有关问题的重要依据，它的轴截面图形、球半径、截面圆半径、圆心距所构成的直角三角形是把空间问题转化为平面问题的主要切入点.2.要正确地区别球面上两点间的直线距离与球面距离.计算A 、B 两点间的球面距离的关键是搞清纬度、经度、纬度差、经度差等概念.●教师下载中心1.要使学生理解两点的球面距离，掌握球的表面积及球的体积公式.求球面面积、球的体积及两点的球面距离是学习本节的重点.2.球是最常见的几何体.高考对球的考查主要在以下四个方面：（1）球的截面的性质；（2）球的表面积和体积；（3）球面上两点间的球面距离；（4）球与其他几何体的组合体.而且多以选择题和填空题的形式出现.第（4）方面有时用综合题进行考查.拓展题例【例1】 如图，一个广告气球被一束入射角为α的平行光线照射，其投影是一个长半轴为5 m 的椭圆，则制作这个广告气球至少需要的面料是__________.解析：长半轴为OA =5，∠AOB =α，设气球半径为r ，则r =5cos α， ∴S =4πr 2=100πcos 2α m 2. 答案：100πcos 2α m 2【例2】 三棱锥A —BCD 的两条棱AB =CD =6，其余各棱长均为5，求三棱锥的内切球半径.解法一：易知内切球球心O 到各面的距离相等.设E 、F 为CD 、AB 的中点，则O 在EF 上且O 为EF 的中点. 在△ABE 中，AB =6，AE =BE =4，OH =873.

Lisa was running late．Lisa, 25, had a lot to do at work, plus visitors on the way: her parents were coming in for Thanksgiving from her hometown．But as she hurried down the subway stairs, she started to feel uncomfortably warln．By the time she got to the platform, Lisa felt weak and tired﹣﹣maybe it hadn't been a good idea to give blood thenight before, she thought．She rested herself against a post close to the tracks．Several yards away, Frank, 43, and his girlfriend, Jennifer, found a spot close to where the front of the train would stop．They were deep in discussion about a house they were thinking of buying．But when he heard the scream, followed by someone yelling, "Oh, my God, she fellin!"Frank didn't hesitate．He jumped down to the tracks and ran some 40feet toward the body lying on the rails．"No!Not you!"his girlfriend screamed after him．She was right to be alarmed．By the time Frank reached Lisa, he could feel the tracks shaking and see the light coming．The train was about 20seconds from the station．It was hard to lift her．She was just out．But he managed to raise her the four feet to theplatform so that bystanders could hold her by the grins and drag her away from the edge．That was where Lisa briefly regained consciousness, felt herself being pulled along the ground, and saw someone else holding her purse．Lisa thought she'd been robbed．A woman held her hand and a man gave his shirt to help stop the blood pouring from her head．And she tried to talk but she couldn't, and that was when she realized how much pain she was in．Police and fire officials soon arrived, and Frank told the story to an officer．Jennifer said her boyfriend was calm on their 40一minute train ride downtown﹣just as he had been seconds after the rescue, which made her think about her reaction at the time．"I saw the train coming and 1was thinking he was going to die, "she explained．（1）What was the most probable cause for Lisa's weakness？________A She had run a long way．B She felt hot in the subway．C She had done a 1ot of work．D She had donated blood the night before．．（2）Why did Jennifer try to stop her boyfriend？________A Because they would miss their train．B Because he didn't see the train coming．C Because she was sure Lisa was hard to lift．D Because she was afraid the train would kill him．．（3）How did Frank save Lisa？________A By lifting her to the platform．B By helping her rise to her feet．C By pulling her along the ground．D By dragging her away from the edge．．（4）When did Lisa become conscious again？________A When the train was leaving．B After she was back on the platform．C After the police and fire officials came．D When a man was cleaning the blood from her head．．（5）The passage is intended to________A warn us of the danger in the subwayB show US how to save people in thesubway C tell US about a subway rescue D report a traffic accident．4. We once had a poster competition in our fifth grade art class．"You could win prizes, ''our teacher told US as she wrote the poster information on the blackboard．She passed out sheets of construction paper while continuing, "The first prize is ten dollars．You just have to make sure that the words on the blackboard appear somewhere on your poster．"We studied the board critically．Some of US looked with one eye and held up certain colors against the blackboard, rocking the sheets to the fight or left while we ________our designs．Others twisted their hair around their fingers or chewed their erasers while deep in thought．We had plans for that ten﹣dollar grand prize, each and every one of US．I'm going to spend mine on candies, one hopeful would announce, while another practiced looking serious, wise and rich．Everyone in the class made a poster．Some of us used parts of those fancy paper napkins, while others used nothing but colored construction paper．Some of US used bigdesigns, and some of us preferred to gather our art tidily down in one comer of our poster and let the space draw the viewer's attention to it．Some of US would wander past the good students'desks and then return to our own projects with a growing sense of hopelessness．It was yet another grown﹣up trick of the soil they seemed especially fond of．making all of US believe we had a fair chance, and then always﹣always﹣rewarding the same old winners．I believe I drew a sailboat, but I can't say that with any certainty．I made it．I admiredit．I determined it to be the very best of all of the posters I had seen, and then I turned it in． Minutes passed．No one came along to give me the grand prize, and then someone distracted me, and I probably never would have thought about that poster again．I was still sitting at my desk, thinking, What poster? When the teacher gave me an envelope with a ten﹣dollar bill in it and everyone in the class applauded for me．（1）What was the teacher's requirement for the poster？________A It must appear in time．B It must be done in class．C It must be done on a construction sheet．D It must include the words on the blackboard．．（2）The underlined phrase in paragraph 3most probably means________．A formed an idea forB made an outline forC made some space forD chose some colors for．（3）After the teacher's words，all the students in the class________．A 1ooked very seriousB thought they would be richC began to think about their designsD began to play games．（4）After seeing the good students'designs，some students________．A 1oved their own designs moreB thought they had a fair chanceC put their own designs in a comerD thought they would not win the prize．（5）We can infer from the passage that the author________．A enjoyed grown﹣up tricks very muchB 1oved poster competitions verymuch C felt surprised to win the competition D became wise and rich after the competition．5. A few years ago I had an"aha!"moment regarding handwriting．I had in my hand a sheet of paper with handwritten instructions on it for some sort of editorial task．It occurred at first that I did not recognize the handwriting, and then I realized whose it must be．I finally became aware of the fact that I had been working with this colleague for at least a year, maybe two, and yet I did not recognize her handwriting at that point．It was a very important event in the computerization of life﹣a sign that the informal．Friendly communication of people working together in an office had changedfrom notes in pen to instant messages and emails．There was a time when our workdays were filled with little letters, and we recognized one another's handwriting the way we knewvoices or faces．As a child visiting my father's office, 1was pleased to recognize, in little notes on the desks of his staff, the same handwriting 1would see at home in the notes he would leave on the fridge﹣except that those notes were signed"dad"instead of"RFW"．All this has been on my mind because of the talk about The Rise and Fall of Handwriting, a book by Florey．Sire shows in her book a deep concern about the fall of handwriting and the failure of schools to teach children to write well, but many others argue that people in a digital age can't be expected to learn to hold a pen．I don't buy it．I don't want to see anyone cut off from the expressive, personal associations that a pen still promotes better than a digital keyboard does．For many a biographer, part of really getting to know their subjects is learning to read their handwriting．What some people advocate is teaching one of the many attractive handwritings based on the handwriting of 16tℎ﹣century Italy．That may sound impossibly grand﹣as if they want kids to learn to draw by copying classical paintings．However, they have worked in many school systems．（1）Why was the author surprised at not recognizing his colleague's handwriting？________ A He had worked with his colleague long enough． B His colleague's handwriting was SO beautiful． C His colleague's handwriting was SO terrible． D He still had a 1ot of Work to do．．（2）People working together in an office used to________．A talk more about handwritingB take more notes on workdaysC know better one another's handwritingD communicate better with one another．（3）The author's father wrote notes in pen________．A to both his family and his staffB to his family in small lettersC to his family on the fridgeD to his staff on the desk．（4）According to the author，handwritten notes________．A are harder to teach in schoolsB attract more attentionC are used only between friendsD carry more message．（5）We can learn from the passage that the author________．A thinks it impossible to teach handwritingB does not want to losehandwriting C puts the blame on the computer D does not agree with Florey．第二节信息匹配（共1小题；每小题10分，满分10分）6.

阅读下面的短文，然后按照要求写一篇150词左右的英语短文．Jackie is perhaps the most easily annoyed koala（考拉）at the Featherdale Wildlife Park in southern Australia．All the koalas there are unhappy and complaining．You would be too ifyou were used to night activities and someone kept waking you up all day while you were trying to sleep it off．That's right﹣sleep it off．The average koala is always half asleep because it feeds on the leaves of a special kind that makes it sleepy．The reason Jackie and her fellow koalas are repeatedly awoken from their deep sleep is so they can be hugged and photographed by tourists，who make the trips to Featherdale and an increasing number of other national parks for just that special experience．Whatever department in the Aussie government in charge of such things is now moving to make the practice illegal，which is understandable．How would you react，my friend，if you were trying to sleep off a dozen times and some round，furry creature smelling of grass kept waking you？*考拉即树袋熊[写作内容]1．以约30个词概括这段短文的内容；2．然后以约120个词就"该不该禁止游客和动物拍照"进行议论，内容包括：（1）人们在参观动物园时为什么喜欢和动物拍照；（2）假如你处在那些动物的处境，你会有什么反应；（3）你认为是否应该禁止游客和动物拍照．[写作要求]1．在作文中可以使用自己亲身的经历或虚构的故事，也可以参照阅读材料的内容但不得直接引用原文中的句子；2．作文中不能出现真实姓名和学校名称．概括准确，语言规范，内容合适，篇章连贯．________________________________．2009年广东省高考英语试卷答案1.

Last weekend，I had an interview with eye﹣doctor Professor Wang about our country primary and middle students'short﹣sightedness．It is said that slightly more than 50% students，which ranks the No.1 in the world，are short﹣sighted．Professor Wang said the reason of short﹣sightedness is complicated and three is still no cure for short﹣sightedness．He suggested that we should not overuse our eyes and do more outdoor exercises．What's more，since the holding of pen has something to do with the short﹣sightedness，we need to pay attention to using the pen．8.
