(1)求圆A 的方程;(2)当|MN|=2√19时,求直线l 的方程.由于圆A 与直线l 1:x+2y+7=0相切,∴R=√5=2√5,∴圆A 的方程为(x+1)2+(y-2)2=20.(2)①当直线l 与x 轴垂直时,易知x=-2与题意相符,使|MN|=2√19.②当直线l 与x 轴不垂直时,设直线l 的方程为y=k (x+2),即kx-y+2k=0,连接AQ , 则AQ ⊥MN ,∵|MN|=2√19,∴|AQ|=1,由|AQ|=√k 2+1=1,得k=34.∴直线l :3x-4y+6=0,故直线l 的方程为x=-2或3x-4y+6=0. 19.(12分)(2020山东,20)如图,四棱锥P-ABCD 的底面为正方形,PD ⊥底面ABCD.设平面PAD 与平面PBC 的交线为l. (1)证明:l ⊥平面PDC ;(2)已知PD=AD=1,Q 为l 上的点,求PB 与平面QCD 所成角的正弦值的最大值.PD ⊥底面ABCD ,所以PD ⊥AD.又底面ABCD 为正方形,所以AD ⊥DC. 所以AD ⊥平面PDC.因为AD ∥BC ,AD 不在平面PBC 中,所以AD ∥平面PBC ,又因为AD ⊂平面PAD ,平面PAD ∩平面PBC=l ,所以l ∥AD.所以l ⊥平面PDC. (2)D 为坐标原点,分别以DA ⃗⃗⃗⃗⃗ ,DC ⃗⃗⃗⃗⃗ ,DP ⃗⃗⃗⃗⃗ 的方向为x 轴,y 轴,z 轴的正方向,建立如图所示的空间直角坐标系Dxyz.由PD=AD=1,得D (0,0,0),C (0,1,0),B (1,1,0),P (0,0,1),则DC ⃗⃗⃗⃗⃗ =(0,1,0),PB ⃗⃗⃗⃗⃗ =(1,1,-1). 由(1)可设Q (a ,0,1),则DQ⃗⃗⃗⃗⃗⃗ =(a ,0,1). 设n =(x ,y ,z )是平面QCD 的法向量,则{n ·DQ⃗⃗⃗⃗⃗⃗ =0,n ·DC ⃗⃗⃗⃗⃗ =0,即{ax +z =0,y =0.可取n =(-1,0,a ).所以cos <n ,PB⃗⃗⃗⃗⃗ >=n ·PB⃗⃗⃗⃗⃗ |n ||PB⃗⃗⃗⃗⃗ |=√3√1+a 2.设PB 与平面QCD 所成角为θ,则sin θ=√33×√1+a 2=√33√1+2a a 2+1.因为√33√1+2a a 2+1≤√63,当且仅当a=1时,等号成立,所以PB 与平面QCD 所成角的正弦值的最大值为√63. 20.(12分)已知抛物线x 2=2py (p>0)的焦点到直线l :x-y-2=0的距离为3√22. (1)求抛物线的标准方程;(2)设点C 是抛物线上的动点,若以点C 为圆心的圆在x 轴上截得的弦长均为4,求证:圆C 恒过定点.x 2=2py 的焦点坐标为(0,p2),由点到直线的距离公式可得(|-p2-2|)√2=3√22, 解得p=2(负值舍去),所以抛物线的标准方程是x 2=4y.C 的坐标为(x 0,x 024),半径为r ,又圆C 在x 轴上截得的弦长为4, 所以r 2=4+(x 024)2,所以圆C 的标准方程为(x-x 0)2+(y -x 024)2=4+(x 024)2,化简得(1-y2)x 02-2xx 0+(x 2+y 2-4)=0,对于任意的x 0∈R ,上述方程均成立,故有{1-y2=0,-2x =0,x 2+y 2=4,解得x=0,y=2,所以圆C 恒过定点(0,2).21.(12分)在矩形ABCD 中,AB=3,AD=2,E 是线段CD 上靠近点D 的一个三等分点,F 是线段AD 上的一个动点,且DF ⃗⃗⃗⃗⃗ =λDA ⃗⃗⃗⃗⃗ (0≤λ≤1).如图,将△BCE 沿BE 折起至△BEG ,使得平面BEG ⊥平面ABED. (1)当λ=12时,求证:EF ⊥BG. (2)是否存在λ,使得FG 与平面DEG 所成的角的正弦值为13?若存在,求出λ的值;若不存在,请说明理由.当λ=12时,F 是AD 的中点,∴DF=12AD=1,DE=13CD=1.∵∠ADC=90°,∴∠DEF=45°.∵CE=23CD=2,BC=2,∠BCD=90°,∴∠BEC=45°.∴BE ⊥EF.又平面GBE ⊥平面ABED ,平面GBE ∩平面ABED=BE ,EF ⊂平面ABED , ∴EF ⊥平面BEG.∵BG ⊂平面BEG ,∴EF ⊥BG.(2)存在.以C 为原点,CD ⃗⃗⃗⃗⃗ ,CB ⃗⃗⃗⃗⃗ 的方向为x 轴,y 轴的正方向建立如图所示的空间直角坐标系. 则E (2,0,0),D (3,0,0),F (3,2λ,0).取BE 的中点O , ∵GE=BG=2,∴GO ⊥BE ,∴易证得OG ⊥平面BCE ,∵BE=2√2, ∴OG=√2,∴G (1,1,√2).∴FG ⃗⃗⃗⃗⃗ =(-2,1-2λ,√2),EG ⃗⃗⃗⃗⃗ =(-1,1,√2),DG ⃗⃗⃗⃗⃗ =(-2,1,√2). 设平面DEG 的一个法向量为n =(x ,y ,z ), 则{n ·DG⃗⃗⃗⃗⃗ =-2x +y +√2z =0,n ·EG ⃗⃗⃗⃗⃗ =-x +y +√2z =0,令z=√2,则n =(0,-2,√2).设FG 与平面DEG 所成的角为θ,则sin θ=|cos <FG ⃗⃗⃗⃗⃗ ,n >|=√6×√6+(1-2λ)=13,解得λ=12或λ=-710(舍去), ∴存在实数λ,使得FG 与平面DEG 所成的角的正弦值为13,此时λ=12. 22.(12分)(2020山东,22)已知椭圆C :x 2a2+y 2b 2=1(a>b>0)的离心率为√22,且过点A (2,1).(1)求C 的方程;(2)点M ,N 在C 上,且AM ⊥AN ,AD ⊥MN ,D 为垂足,证明:存在定点Q ,使得|DQ|为定值. 由题设得4a 2+1b 2=1,a 2-b 2a 2=12,11 解得a 2=6,b 2=3,所以C 的方程为x 26+y 23=1.M (x 1,y 1),N (x 2,y 2).若直线MN 与x 轴不垂直,设直线MN 的方程为y=kx+m ,代入x 26+y 23=1得(1+2k 2)x 2+4kmx+2m 2-6=0.于是x 1+x 2=-4km 1+2k 2,x 1x 2=2m 2-61+2k 2.由AM ⊥AN 知AM ⃗⃗⃗⃗⃗⃗ ·AN ⃗⃗⃗⃗⃗⃗ =0,故(x 1-2)(x 2-2)+(y 1-1)(y 2-1)=0,可得(k 2+1)x 1x 2+(km-k-2)(x 1+x 2)+(m-1)2+4=0.整理得(2k+3m+1)(2k+m-1)=0.因为A (2,1)不在直线MN 上,所以2k+m-1≠0,故2k+3m+1=0,k ≠1. 于是MN 的方程为y=k (x -23)−13(k ≠1).所以直线MN 过点P (23,-13).若直线MN 与x 轴垂直,可得N (x 1,-y 1).由AM ⃗⃗⃗⃗⃗⃗ ·AN ⃗⃗⃗⃗⃗⃗ =0得(x 1-2)(x 1-2)+(y 1-1)(-y 1-1)=0.又x 126+y 123=1,可得3x 12-8x 1+4=0.解得x 1=2(舍去)或x 1=23.此时直线MN 过点P (23,-13).令Q 为AP 的中点,即Q (43,13).若D 与P 不重合,则由题设知AP 是Rt △ADP 的斜边,故|DQ|=12|AP|=2√23.若D 与P 重合,则|DQ|=12|AP|.综上,存在点Q (43,13),使得|DQ|为定值.。

2010年上海高考英语阅读理解新题型13文来高中Section ＤDirections:Read the following passage and complete the sentences or answer the questions according to the information given in the passage you have just read.Writing being largely a self-taught occupation, texts on how to get about it —though great in number— seldom are of much use.You try, and fail. Then try again, and perhaps fail not quite so grievously. Until at last, if you have some gift for it, the failures become less frequent, or at any rate less noticeable.It is this ability to conceal one’s defects（瑕疵）that passes, finally, for accomplishment.Along the way there are the discouragements of unkind criticism, outright rejection, nagging insecurity and irregular inability to meet debts.It is uncommon, therefore, to come across a book containing advice of much practical value for anyone toying with the dangerous idea of staring on a writing life.A friend recently loaned me such a book, however —one I wish I’d had the luck to read years ago, and which I would commend to any young person bent on making a career of words. It is the autobiography of the English novelist Anthony Trollope, first published in 1883, the year after his death.Needing some means to support himself, Trollope at age 19 signed on as a junior clerk in the British postal service. He was at his desk at 5:30 each morning to write for three hours. And he remained in the mail service 33 years, long after reputation and prosperity had come to him.Now, what of his advice?1. For safety’s sake, arm yourself with some other skills, some other line of work to fall back on. That way, failure at writing, though the disappointment may be keen, will not mean utter ruin.2. Do not depend overly much on inspiration. Writing is a craft, which Trollope compared to the craft of shoemaking. The shoemaker who has just turned out one pair of his work sets to work immediately on the next pair.3. Have a story to tell, but, more important than that, people it with characters who will speak and move as living creatures in the reader’s mind. Without memorable c haracters, story alone is nothing.4. Meet your deadlines. Life is endlessly “painful and troublesome” for writers who can’t finish their work on time.5. Do not be inflated by praise. And, above all, do not be crushed by criticism.6. Understand the risks of writing for a living. “The career, when successful, is pleasant enough certainly; but when unsuccessful, it is of all careers the most painful.”1. What is the passage mainly about?2. From the context, what does the phrase “pass for” in Paragraph 3 mean?3. According to the author, what is the definition of writing ?4. What is the author ’s most probable profession?Keys:1. The passage is mainly about sound advice provided in A. Trollope’s autobiography.2. It means “be regarded as”.3. Writing is basically a self-taught occupation and no instructions on how to deal with it are of any practical use.4. He is most probably a writer.Section ＤDirections:Read the following passage and complete the sentences or answer the questionsaccording to the information given in the passage you have just read.A long-awaited final report from the Food and Drug Administration (FDA) concludes that foodsfrom healthy cloned animals and their offspring are as safe as those from ordinary animals, effectively removing the last US regulatory barrier to the marketing of meat and milk from cloned cattle, pigs and goats.The 968-page "final risk assessment," not yet released but obtained by The Washington Post, finds no evidence to support people’s concerns that fo od from clones may have hidden risks.But, recognizing that a majority of consumers are wary of food from clones—and that cloning could damage the good image of American milk and meat—the report includes hundreds of pages of raw data so that others can see how it came to its conclusions.The report also acknowledges that human health concerns are not the only subject raised by the coming-out of cloned farm animals.“Moral, religious and ethical concerns have been raised,” the agency notes in a document acco mpanying the report. But the report is “exactly a science-based assessment.” It reports, because the agency is not authorized by law to consider those issues.In practice, it will be years before foods from clones make their way to store shelves in large quantities, in part because the clones themselves are too valuable to kill or milk. Instead, the expensive animals — replicas(复制品) of some of the finest farm animals ever born — will be used firstly as breeding stock to create what supporters say will be a new generation of superior farm animals.When food from those animals hits the market, the public may yet have its say. FDA officials have said they do not expect to require food from clones to be labeled as such, but they may allow foods from ordinary animals to be labeled as not from clones.1. What conclusion has FAD drawn after the public waited for a long time?2. Foods from clones won’t be available soon partly because __________________________.3. With the appearance of cloned farm animals, people care more about _________________________________________________________________ problems.4. How will foods from ordinary animals be labeled?Keys:1. FDA made the conclusion that foods from healthy cloned animals and their offspring are as safe as those from ordinary animals.2. the clones themselves are too valuable to kill or milk.3. human health, moral, religious and ethical4. They will be allowed to be labeled as not from clones.Section ＤDirections:Read the following passage and complete the sentences or answer the questions according to the information given in the passage you have just read.President Barack Obama met briefly with his half brother, Mark Okoth Obama Ndesandjo, who lives in China since 2002.The three chatted on Monday night, with Obama being introduced to Ndesandjo's wife, a native of Henan, China, whom he married a year ago.“I think he came directly off the plane, changed some clothes and then came down and saw us.” Ndesandjo said, "And he just gave me a big hug. And it was so intense. I'm still over the moon on it. And my wife is also on the top of the world. She is his biggest fan and I think she is still recovering."In the CNN interview, president Obama told CNN ,"I don't know him well. We did not grow up together. I met him for the first time a couple of years ago.” The president said he hadn't read his brother's book, "Nairobi to Shenzhen," which features a boy who is the son of a Jewish mother and an abusive father from Kenya. Ndesandjo recently wrote this novel about the abusive Kenyan father they share, Obama Senior. In his book, Mark wrote : “My father beat my mother and also beat me. ”Ndesandjo said it took a long time for him to become "proud to be an Obama."The president himself also wrote about his father, who abandoned him as a child, in his best-selling memoir , “Dreams From My Father”. “It's no secret that my father was a troubled person,” President Obama said. “he had an alcoholism problem. He didn't treat his families very well. Obviously it's a sad part of my history and my background.”Ndesandjo said he bought tickets months ago to fly from the southern boomtown of Shenzhen, where he has lived, to Beijing, in hopes of reconnecting with his brother. The two last met in Januarywhen Ndesandjo attended Obama's inauguration as a family guest.Ndesandjo , the 43-year-old businessman and musician , earns a living as a marketing consultant in Shenzhen, near Hongkong. He earned degrees in physics from Brown University and Stanford and an MBA from Emory University. As a classical and jazz pianist, Ndesandjo also volunteers as a piano teacher in an orphanage. His fluent spoken and written Chinese impress many Chinese. "Mark is very smart and multitalented," wrote one state news agency. However, for most of time he has maintained a low profile, having repeatedly turned down offers from Chinese companies to be a product spokesman.1. Do president Obama and his brother feel proud of their father? What was their father like?2. When and on what occasion did the two brothers meet before Obama’s vist to Beijing?3. Why is Nesandjo constantly invited by the Chinese companies to be a product spokesman?4. We can tell from the passage that President Obama’s half brother is a caring person from the factthatKeys:1.No, they don’t. He was a troubled person.2.They last met in January when Ndesandjo attended Obama's inauguration as a family guest.3.He is now a celebrity because of his connection with the president./ He’s now famous……4.he also volunteers as a piano teacher in an orphanage.Section ＤDirections:Read the following passage and complete the sentences or answer the questionsaccording to the information given in the passage you have just read.Chinese Premier Wen Jiabao will meet here Wednesday with US President Barack Obama, who is on his first state visit to China since his January inauguration（就职典礼）.They will have a working lunch before Obama's sightseeing visit to the Great Wall in the north suburb of the Chinese capital, which will be another chance for the US head of state, who toured the Imperial Palace Tuesday, to learn more about the ancient Chinese civilization.Obama will conclude his fist visit to China and fly to the Republic of Korea, the last leg of his four-state Asian tour, in the afternoon.He arrived in China's economic hub Shanghai Sunday night to kick off this visit as guest of his Chinese counterpart Hu Jintao. Hu held talks with him in Beijing on Tuesday and they met international reporters for about 40 minutes after the talks, both pledging to further bilateral ties.Top Chinese legislator Wu Bangguo also met Obama on Tuesday, several hours before a state banquet in the Great Hall of the People in downtown Beijing.In a joint statement issued on Tuesday, the two sides spoke highly of the tremendous development achieved since the two countries established diplomatic relations 30 years ago and reached consensus on further bilateral ties.1.
