(2)解:∵四边形ABCD 为矩形, ∴BO=DO =12BD.∴S △OCD =S △OCB =12S △ABC =12×12×3×4=3.∴S 菱形OCED =2S △OCD =6.21.(1)证明:在△BCE 与△DCF 中, ⎩⎪⎨⎪⎧BC =DC ,∠BCE=∠DCF,CE =CF , ∴△BCE≌△DCF. (2)解:∵△BCE≌△DCF, ∴∠EBC=∠FDC=30°. ∵∠BCD=90°,∴∠BEC=60°. ∵EC=FC ,∠ECF=90°, ∴∠CEF=45°.∴∠BEF=105°.22.(1)证明:∵在矩形ABCD 中,AD∥BC,∠A=∠C=90°, ∴∠ADB=∠DBC.根据折叠的性质得∠ADB=∠BDF,∠F=∠A=90°, ∴∠DBC=∠BDF ,∠C=∠F. ∴BE=DE.在△DCE 和△BFE 中, ⎩⎪⎨⎪⎧∠DEC=∠BEF,∠C=∠F,DE =BE , ∴△DCE≌△BFE. (2)解:在Rt △BCD 中, ∵CD=2,∠ADB=∠DBC=30°, ∴BD=4.∴BC=2 3.在Rt △ECD 中,易得∠EDC=30°. ∴DE=2EC. ∴(2EC)2-EC 2=CD 2. ∵CD=2, ∴CE=233.∴BE=BC -EC =433.(第23题)23.(1)证明:如图,连接AC. ∵四边形ABCD 为菱形,∠BAD=120°,∴∠ABE=∠ACF=60°,∠1+∠2=60°.∵∠3+∠2=∠EAF=60°,∴∠1=∠3.∵∠ABC=60°,AB=BC,∴△ABC为等边三角形.∴AC=AB.∴△ABE≌△ACF.∴BE=CF.(2)解:四边形AECF的面积不变.由(1)知△ABE≌△ACF,则S△ABE=S△ACF,故S四边形AECF=S△AEC+S△ACF=S△AEC+S△ABE=S△ABC. 如图,过A作AM⊥BC于点M,则BM=MC=2,∴AM=AB2-BM2=42-22=2 3.∴S△ABC=12BC·AM=12×4×23=4 3.故S四边形AECF=4 3.24.解:(1)OE=OF.理由如下:∵CE是∠ACB的平分线,∴∠ACE=∠BCE.又∵MN∥BC,∴∠NEC=∠BCE.∴∠NEC=∠ACE.∴OE=OC.∵CF是∠ACD的平分线,∴∠OCF=∠FCD.又∵MN∥BC,∴∠OFC=∠FCD.∴∠OFC=∠OCF.∴OF=OC.∴OE=OF.(2)当点O运动到AC的中点,且△ABC满足∠ACB为直角时,四边形AECF是正方形.理由如下:∵当点O运动到AC的中点时,AO=CO,又∵EO=FO,∴四边形AECF是平行四边形.∵FO=CO,∴AO=CO=EO=FO.∴AO+CO=EO+FO,即AC=EF.∴四边形AECF是矩形.已知MN∥BC,当∠ACB=90°时,∠AOE =90°,∴AC⊥EF.∴四边形AECF是正方形.(3)不可能理由如下:连接BF,∵CE平分∠ACB,CF平分∠ACD,∴∠ECF=12∠ACB+12∠ACD=12(∠ACB+∠ACD)=90°.若四边形BCFE是菱形,则BF⊥EC.但在一个三角形中,不可能存在两个角为90°,故四边形BCFE不可能为菱形.第二章达标检测卷(120分,90分钟)一、选择题(每题3分,共30分)1.下列方程一定是一元二次方程的是( )A .3x 2+2x-1=0 B .5x 2-6y -3=0 C .ax 2-x +2=0 D .3x 2-2x -1=02.一元二次方程5x 2-x =-3,其中二次项系数、一次项系数、常数项分别是( )A .5,-x ,3B .5,-1,-3C .5,-1,3D .5x 2,-1,33.由下表估算一元二次方程x 2+12x =15的一个根的范围,正确的是( )A .1.0<x<1.1B .1.1<x<1.2C .1.2<x<1.3D .14.41<x<15.844.设α,β是一元二次方程x 2+2x -1=0的两个根,则αβ的值是( )A .2B .1C .-2D .-15.为解决群众看病贵的问题,有关部门决定降低药价,对某种原价为289元的药品进行连续两次降价后为256元,设平均每次降价的百分率为x ,则下面所列方程正确的是( )A .289(1-x)2=256B .256(1-x)2=289C .289(1-2x)=256D .256(1-2x)=2896.下列方程,适合用因式分解法解的是( )A.x2-42x+1=0 B.2x2=x-3C.(x-2)2=3x-6 D.x2-10x-9=07.关于x的方程x2-ax+2a=0的两根的平方和是5,则a的值是( )A.-1或5 B.1 C.5 D.-18.一个三角形的两边长分别为3和6,第三边的长是方程(x-2)(x -4)=0的根,则这个三角形的周长是( )A.11 B.11或13 C.13 D.以上选项都不正确9.若一元二次方程x2-2x-m=0无实数根,则一次函数y=(m+1)x +m-1的图象不经过第( )象限.A.四B.三C.二D.一(第10题)10.如图,将边长为2 cm的正方形ABCD沿其对角线AC剪开,再把△ABC沿着AD方向平移,得到△A′B′C′,若两个三角形重叠部分的面积为1 cm2,则它移动的距离AA′等于( )A.0.5 cm B.1 cmC.1.5 cm D.2 cm二、填空题(每题3分,共24分)11.若将方程x2-8x=7化为(x-m)2=n,则m=________.12.如果关于x的方程ax2+2x+1=0有两个不相等的实数根,那么实数a的取值范围是______________.13.已知关于x的方程x2-6x+k=0的两根分别是x1,x2,且满足1x1+1x2=3,则k=________.14.某市准备加大对雾霾的治理力度,2015年第一季度投入资金100万元,第二季度和第三季度共投入资金260万元,求这两个季度投入资金的平均增长率.设这两个季度投入资金的平均增长率为x,根据题意可列方程为________________________.15.关于x的两个方程x2-4x+3=0与1x-1=2x+a有一个解相同,则a=________.16.小明的妈妈周三在自选商场花10元钱买了几瓶酸奶,周六再去买时,正好遇上商场酬宾活动,同样的酸奶,每瓶比周三便宜0.5元,结果小明的妈妈只比上次多花了2元钱,却比上次多买了2瓶酸奶,她周三买了________瓶酸奶.17.对于实数a,b,定义运算“*”a* b=22(),(), a ab a b ab b a b ⎧-≥⎪⎨-⎪⎩<例如:4*2,因为4>2,所以4*2=42-4×2=8.若x1,x2是一元二次方程x2-5x+6=0的两个根,则x1*x2=________.(第18题)18.如图,在Rt△ABC中,∠BAC=90°,AB=AC=16 cm,AD为BC 边上的高,动点P从点A出发,沿A→D方向以 2 cm/s的速度向点D运动.设△ABP的面积为S1,矩形PDFE的面积为S2,运动时间为t s(0<t<8),则t=________时,S1=2S2.三、解答题(19题12分,20~23题每题8分,24题10分,25题12分,共66分)19.用适当的方法解下列方程.(1)x2-x-1=0; (2)x2-2x=2x+1;(3)x(x-2)-3x2=-1; (4)(x+3)2=(1-2x)2.20.已知关于x的一元二次方程(m+1)x2-x+m2-3m-3=0有一个根是1,求m的值及另一个根.21.晓东在解一元二次方程时,发现有这样一种解法:如:解方程x(x+4)=6.解:原方程可变形,得[(x+2)-2][(x+2)+2]=6.(x+2)2-22=6,(x+2)2=6+22,(x+2)2=10.直接开平方并整理,得x1=-2+10,x2=-2-10.我们称这种解法为“平均数法”.(1)下面是晓东用“平均数法”解方程(x+2)(x+6)=5时写的解题过程.解:原方程可变形,得[(x+□)-○][(x+□)+○]=5.(x+□)2-○2=5,(x+□)2=5+○2.直接开平方并整理,得x1=☆,x2=¤.上述过程中的“□”,“○”,“☆”,“¤”表示的数分别为________,________,________,________.(2)请用“平均数法”解方程:(x-3)(x+1)=5.22.已知x1,x2是关于x的一元二次方程(a-6)x2+2ax+a=0的两个实数根.(1)是否存在实数a,使-x1+x1x2=4+x2成立?若存在,求出a 的值;若不存在,请说明理由.(2)求使(x1+1)(x2+1)为负整数的实数a的整数值.23.楚天汽车销售公司5月份销售某种型号汽车.当月该型号汽车的进价为30万元/辆,若当月销售量超过5辆时,每多售出1辆,所有售出的汽车进价均降低0.1万元/辆.根据市场调查,月销售量不会突破30辆.(1)设当月该型号汽车的销售量为x辆(x≤30,且x为正整数),实际进价为y万元/辆,求y与x的函数关系式;(2)已知该型号汽车的销售价为32万元/辆,公司计划当月销售利润为25万元,那么该月需售出多少辆汽车?(注:销售利润=销售价-进价)24.如图,A,B,C,D为矩形的四个顶点,AB=16 cm,AD=6 cm,动点P ,Q 分别从点A ,C 同时出发,点P 以3 cm /s 的速度向点B 移动,一直到达B 为止,点Q 以2 cm /s 的速度向D 移动.(1)P ,Q 两点从出发开始到几秒时,四边形PBCQ 的面积为33 cm 2?

15.1816.38点拨:列表如下:由表格可知共有16种等可能情况,参加首场比赛的两个队都来自县区学校的有6种情况,所以概率为616=38.17.31018.716点拨:列表如下:(第18题)由表格知共有16种等可能的结果,而落在以A(-2,0),B(2,0),C(0,2)为顶点的三角形内(包含边界)的点有(-2,0),(0,0),(1,0),(2,0),(0,1),(1,1),(0,2),共7种,如图,所以点M落在以A(-2,0),B(2,0),C(0,2)为顶点的三角形内(包含边界)的概率是716 .三、19.解:列表如下:由表格可看出,所有可能出现的结果共有12种,每种结果出现的可能性都相同,其中抽到的两张硬纸片上的图形既是轴对称图形又是中心对称图形的结果共有2种,故所求概率P =212=16.20.解:设原来瓶中幸运星大约有x 颗,则有20x =630.解得x =100.经检验,符合题意.∴原来瓶中幸运星大约有100颗.21.解:某人从钱包内随机取出2张纸币,可能出现的结果有3种,即10元与20元,10元与50元,20元与50元,并且它们出现的可能性相等.(1)取出纸币的总额是30元(记为事件A)的结果有1种,即10元与20元,所以P(A)=13.(2)取出纸币的总额可购买一件51元的商品(记为事件B)的结果有2种,即10元与50元,20元与50元,所以P(B)=23.22.解:(1)20 (2)补图如图所示.(第22题)(3)列表如下,A 类学生中的两名男生分别记为男A 1和男A 2,共有6种等可能的结果,其中,一男一女的有3种,所以恰好选中一名男生和一名女生的概率为36=12.23.解:(1)所求概率P =36=12.(2)游戏公平. 理由如下:由上表可知,共有36种等可能的结果,其中小亮、小丽获胜各有9种结果,∴P(小亮胜)=936=14,P(小丽胜)=936=14.∴该游戏是公平的.24.解:(1)画树状图如图所示:(第24题)或列表如下:共有6种选购方案:(高档,精装)、(高档,简装)、(中档,精装)、(中档,简装)、(低档,精装)、(低档,简装).(2)因为选中甲厂家的高档粽子的方案有2种,即(高档,精装)、(高档,简装),所以甲厂家的高档粽子被选中的概率为26=13.(3)由(2)可知,当选用方案(高档,精装)时,设分别购买高档粽子、精装粽子x 1盒、y 1盒,根据题意,得⎩⎪⎨⎪⎧x 1+y 1=32,60x 1+50y 1=1 200. 解得⎩⎪⎨⎪⎧x 1=-40,y 1=72.经检验,不符合题意,舍去.当选用方案(高档,简装)时,设分别购买高档粽子、简装粽子。

(A)In 1977, a dead author of detective stories saved the life of a 19-month-old baby in a most unusual way. The author was Agatha Christie, one of the most successful writers of detective stories in the world.In June 1977, a baby girl became seriously ill in Qatar, near Saudi Arabia. Doctors were unable to find out the cause of her illness with confidence, so she was sent to Hammersmith Hospital in London. She was then only semi-conscious and on the "Dangerously Ill" list. A team of doctors hurried to examine the baby only to discover that they, too, were confused by the very unusual symptoms (症状). While they were discussing the baby's case, a nurse asked to speak to them."Excuse me," said Nurse Marsha Maitlan, "but I think the baby is suffering from thallium (铊) poisoning.""What makes you think that?" Dr. Brown asked. "Thallium poisoning is extremely rare.""A few days ago, I was reading a novel called A Pale Horse by Agatha Christie," Nurse Maitlan explained. "In the book, somebody uses thallium poison, and all the symptoms are described. They're exactly the same as the baby's.""You're very thoughtful and you may be right," another doctor said. "We'll carry out some tests and find out whether it's thallium or not."Tests showed that the baby had indeed been poisoned by thallium, a rare metallic substance used in making special glass. Once they knew the cause of the illness, the doctors were able to give the baby the correct treatment. She soon recovered and was sent back to Qatar. Later it was reported that the poison might have come from an insecticide (杀虫剂) used in Qatar.46. The one who first suggested the correct cause of the baby's illness was _____.A. a doctor in QatarB. Nurse MaitlanC. Dr. BrownD. Agatha Christie47. The baby was sent to London because _____.A. she was born thereB. the hospitals in Qatar were full at that timeC. she was the daughter of a doctor in LondonD. the Qatar doctors were not sure whether they could cure her48. As far as we can tell from the passage, Agatha Christie _____.A. had never met this babyB. had spent a long time studying the baby's caseC. visited the baby in the hospital at HammersmithD. gave Nurse Maitlan some advice on the phone49. It seems likely from the passage that the baby's illness had something to do with _____.A. a dangerous pair of glassesB. the water in QatarC. a harmful substance used to kill insectsD. a dead writer50. The underlined word “substance” is in closest meaning to _______A. matterB. illnessC. treatmentD. glass(B)Popeye the Sailor first became a popular cartoon in the 1930s.The sailor in that cartoon ate lots of spinach to make him strong. People watched him, and they began to buy and eat a lot more spinach. Popeye helped sell 33 percent more spinach than befor e! Spinach became a necessary part of many people’s diets. Even some children who hated the taste began to eat the vegetable.Many people thought that the iron in spinach made Popeye strong, but this is not true. Spinach does not have any more iron than any other green vegetable.People only thought spinach had a lot of iron because the people who studied the food made a mistake. In the 1890s, a group of people studied what was inside vegetables. This group said that spinach had ten times more iron than it did. The group wrote the number wrong, and everyone accepted it.Today, we know that the little iron there is in spinach cannot make a difference in how strong a person is. However, spinach does have something else which the body needs—folic acid.It is interesting to point out that folic acid can help make a person strong. Maybe it was really the folic acid that made Popeye strong all along.51. A good title for this reading passage is______.A. Popeye the SailorB. The Truth About SpinachC.A Mistake with NumbersD. Folic Acid Makes You Strong52. Why did many people eat spinach after they saw Popeye the Sailor?A. They thought spinach made them strong.B. They thought Popeye was funny.C. Spinach had a lot of iron.D. People liked folic acid.53. A research group told people that spinach______.A. made Popeye strongB. was a green vegetableC. had less iron than other green vegetablesD. had more iron than other green vegetables54. The reading passage says that perhaps Popeye got his strength from______.A. ironB. folic acidC. spinachD. exercise55. Folic acid is ______.A. something in foodB. a vegetableC. dangerousD. a certain kind of spinach( C )My father had returned from his business visit to London when I came in, rather late, to supper. I could tell at once that he and my mother had been discussing something. In that half-playful, half-serious way I knew so well, he said, "How would you like to go to Eton?""You bet," I cried quickly catching the joke. Everyone knew it was the most expensive, the most famous of schools. You had to be entered at birth, if not before. Besides, even at 12 or 13, I understood my father. He disliked any form of showing off. He always knew his proper position in life, which was in the middle of the middle class, our house was medium-sized; he had avoided joining Royal Liverpool Golf Club and went to a smaller one instead; though once he had got a second-handRolls-Royce at a remarkably low price, he felt embarrassed driving it, and quickly changed it for an Austin 1100.This could only be his delightful way of telling me that the whole boarding school idea was to be dropped. Alas! I should also have remembered that he had a liking for being different from everyone else, if it did not conflict(冲突) with his fear of drawing attention to himself.It seemed that he had happened to be talking to Graham Brown of the London office, a very nice fellow, and Graham had a friend who had just entered his boy at the school, and while he was in that part of the world he thought he might just as well phone them. I remember my eyes stinging(刺痛) and my hands shaking with the puzzlement of my feelings. There was excitement, at the heart of great sadness."Oh, he doesn't want to go away," said my mother, "You shouldn't go on like this.” “It's up to him," said my father. "He can make up his own mind."56. The house the writer's family lived in was ________.A. the best they could affordB. right for their social positionC. for showing offD. rather small57. His father sold his Roils-Royce because ________.A. it made him feel uneasyB. it was too old to work wellC. it was too expensive to possessD. it was too cheap58. The writer's father enjoyed being different as long as ________.A. it drew attention to himB. it didn't bring him in argumentsC. it was understood as a jokeD. there was no danger of his showing off59. What was the writer's reaction to the idea of going to Eton?A. He was very unhappy.B. He didn't believe it.C. He was delighted.D. He had mixed feelings.60. We can know from the passage that ________.A. Children who can go to Eton are very famousB. Children can go to Eton if they willC. It is very difficult for a child to get admitted by EtonD. Children don't have the right to decide whether they will go to Eton(D)Researches have shown that music has an important effect on one’s body and mind. In fact, there is a growing field of health care known as Music Therapy, which uses music to treat diseases. Even hospitals are beginning to use music therapy. This is not surprising, as music affects the body and mind in many powerful ways.Researches have shown that quick music can make a person feel more alert (警觉的), while slow music can produce a calm, deep thinking state. Also, researches have found that music can change brainwave activity levels. This can help the brain to change speeds more easily on its own as needed, which means that music can bring lasting benefits to your state of mind, even after you’ve stopped listening.Breathing and heart rate can also be influenced by music. This can mean slower breathing, slower heart rate, and a relaxing response. This is why music and music therapy can help reduce the damaging effects of long-term stress, greatly promoting (促进) not only relaxation, but health.Music can also be used to bring about a more positive state of mind, by helping to keep worries away. Music has also been found to bring many other benefits, suchas lowering blood pressure and reducing the risk of strokes among others. It is no surprise that so many people are considering music as an important tool to help the body become or stay healthy.61. What can we know about music therapy?A. It is a type of music.B. It is a research about music.C. It is a kind of disease affected by music.D. It is a method of using music to help treat diseases.62. According to the second paragraph, we can know that ________.A. music with different speeds has different effectsB. quick music is not good for one’s healthC. slow music can help one think more slowlyD. music will have less benefits after one stops listening63. The reason why music can help deal with stress is that ________.A. it is used by many hospitalsB. it can help change brainwavesC. it is beneficial to breathing and heart rateD. it can bring a more positive state of mind64. According to the passage, music can help deal with all the following EXCEPT ________.A. nervousnessB. mind illnessesC. strokesD. high blood pressure65. The passage is mainly about _________.A. the importance of music therapyB. the benefits music can bring to treat diseasesC. a research on the effect of musicD. the diseases music can help to treat第二节信息匹配(共5小题;每小题2分,满分10分)阅读下列应用文及相关信息,并按照要求匹配信息。
