(6分)(2)设{}n a 的公差为d ,因为1sin 1a A =,且2a ,4a ,8a 成等比数列,所以112sin a A==,且2428a a a =⋅, 所以()()()211137a d a d a d +=++,且0d ≠,解得2d =, 所以2n a n =,所以()141=+1n n a a n n += 111n n -+,所以1111223n S ⎛⎫⎛⎫=-+-+ ⎪ ⎪⎝⎭⎝⎭ 1111341n n ⎛⎫⎛⎫-++-= ⎪ ⎪+⎝⎭⎝⎭1111n n n -=++. (12分) 18.(本小题满分12分)证明:(1)∵PB PD =,且O 为BD 中点,∴BD PO ⊥.在菱形ABCD 中,∵60=∠BCD ,2=AB ,∴3=OA ,1=OB .又2=PB ,∴3=PO . ∵6=PA ,∴222OA PO PA +=,OA PO ⊥.∵O AO BD =⋂,∴⊥PO 平面ABCD ; (5分)(2)①∵231=⨯=-PO S V ABCD ABCD P , ∴21=-PADM V ,即2131=⨯∆PO S MAD ,∴1=DM ,M 为CD 的中点. (7分) ②作MN ∥OC 交BD 与点N ,连结PN .∵BD AC ⊥,PO AC ⊥,∴⊥AC 平面PBD ,∴⊥MN 平面PBD ,MPN ∠是MP 与平面PBD 所成的角. ∵2321==OC MN ,21322=+=ON PO PN , ∴1339tan ==∠PN MN MPN . (12分) 19.(本小题满分12分)解:(1)∵我校共有100名文科学生参加考试,其中语文考试成绩低于130的有94%人,∴语文成绩特别优秀的概率为p 1=1﹣0.94=0.06, ∴语文特别优秀的同学有100×0.06=6人, ∵数学成绩特别优秀的概率为p 2=0.002×20=0.04,∴数学特别优秀的同学有100×0.04=4人. (4分) (2)语文数学两科都优秀的有3人,单科优秀的有4人,记两科都优秀的3人分别为A 1、A 2、A 3,单科优秀的4人分别为B 1、B 2、B 3、B 4,从中随机抽取2人,共有:(A 1,A 2)、(A 1,A 3)、(A 2,A 3)、(A 1,B 1)、(A 1,B 2)、(A 1,B 3)、(A 1,B 4)、(A 2,B 1)、(A 2,B 2)、(A 2,B 3)、(A 2,B 4)、(A 3,B 1)、(A 3,B 2)、(A 3,B 3)、 (A 3,B 4)、(B 1,B 2)、(B 1,B 3)、(B 1,B 4)、(B 2,B 3)、(B 2,B 4)、(B 3,B 4)21种,其中这两人两科成绩都优秀的有:(A 1,A 2)、(A 1,A 3)、(A 2,A 3)3种, ∴这两人两科成绩都优秀的概率71213==P . (8分) (3)2×2列联表:∴635.6173.35946964)31933(10022>≈⨯⨯⨯⨯-⨯=K , ∴有99%的把握认为语文特别优秀的同学,数学也特别优秀. (12分)20.(本小题满分12分)解:(1)设圆P 的半径为R ,圆心P 的坐标为),(y x ,由于动圆P 与圆64)2(:22=++y x M 相切,且与圆4)2(:22=+-y x N 相内切,所以46)2()8(=>=-+-=+MN R R PN PM . 所以圆心P 的轨迹是以点M ,N 为焦点的椭圆,且3=a ,2=c ,则5222=-=c a b ,所以曲线C 的方程为15922=+y x . (5分) (2)由题意,设),(11y x A ,),(22y x B ,直线AB 的方程为2-=my x .由⎪⎩⎪⎨⎧=+-=159222y x m y x 可得02520)95(22=--+my y m ,则9520221+=+m m y y ,9525221+-=m y y , 所以]95100)9520)[(1(]4))[(1(2222212212++++=-++=m m m m y y y y m AB 95)1(3022++=m m .因为AB ∥,所以TAB ∆的面积等于OAB ∆的面积. 又点O 到直线AB 的距离122+=m d ,所以TAB ∆的面积951301295)1(30212122222++=+⋅++⋅=⋅=m m m m m d AB S , 因为TAB ∆面积为310,所以3109513022=++m m ,解得0=m ,故直线AB 方程为2-=x .(12分) 21.(本小题满分12分) 解:0)(>'x f ,)(x f 单调递增;0)<,)(x f 单调递减;当0>m 时,01>+mx ,故0)(>'x f ,即)(x f 在),0(+∞上单调递增. 当0≥m 时,)(x f 的单调递增区间为),0(+∞.

But if you gain 5, 10, or even 20 pounds every winter, you may be suffering from more than just a sweet tooth. Seasonal Affective Disorder (SAD) often leads to significant weight gain in the colder, darker months.“People with SAD want sugar, starchy (含有淀粉的) food because they increase serotonin (血清素) levels,” says Dr. Norman Rosenthal, a leading seasonal depression expert. “ For most people, the result of eating a lot of carbohydrates (碳水化合物) is weight gain. But for people with SAD, in addition to weight gain, there is also a mood ride between highs and lows.”Plus, according to recent studies, people with SAD may have a naturally slower metabolism (新陈代谢) than others.“Because SAD arrives predictably at the same time every year, you have the opportunity to plan ahead,”writes Dr. Rosenthal. For more than 30 years, he has studied SAD and its treatments. He also suffers from the disorder himself. “ As the sunlight disappeared, so did my energy. I felt really tired and sad. Cookies and candy became a source of comfort in the cold winter.”One of the most difficult aspects of the disorder is that the sadness and gloom are not constant. So it is easy to deny the problem.But it is time to bring SAD into the light. “ I began to exercise regularly. I changed my diet to emphasize lean protein, vegetables and low-impact carbohydrates,”he writes. “Although I accept that winter may not feel as good as summer, I have reclaimed a sense of well-being.”So, cheer up. You aren’t a glutton (贪吃的人), eating senselessly over the holidays! No, you may have seasonal affective disorder!36.What can we infer from the first paragraph?A.People are more likely to gain weight in summer holiday.B.Seasonal affective disorder often leads to significant weight gain in winter.C.If you put on weight in winter, you must be suffering from a sweet tooth.D.You can plan ahead to prevent SAD.37.Why do people with SAD want to have sugary, starchy foods?A.Because they increase serotonin levels and make them feel happy.B.Because they have a slower metabolism than others.C.Because they are easy to be hungry.D.Because they can increase the blood sugar level.38.If you have SAD, ________.A.maybe you gain more than 10 pounds every winterB.you may be afraid of seeing sunlightC.you want to have salty food in winterD.you stay active in winter39.Which one is NOT a symptom of SAD, according to the passage?A.A feeling of wanting to have sugary, starchy foods.B.A feeling of tiredness or sadness during the winter.C.A significant weight gain in the colder, darker months.密学校 班级姓名 学号密 封 线 内 不 得 答 题D.

乡村传统文化现实境遇与发展机会①乡村传统文化赋予了传统乡村生活以规则、意义和价值,是乡村村民日常生活中常态性和当然性的文化。

然而,随着村民们越来越多地接触到外面精彩世界,他们生存和发展的愿望有了新的参照系,部分人特别是青壮年渐渐感觉乡村生活很难体现人的生存价值,对乡村生活的意义产生了怀疑。

而且他们在向往城市生活、崇拜外来文化的同时,也日益对乡土传统文化产生疏离感和自卑感。

②传统民族乡村社会里,村落中辈分最长的能人常常拥有着知识、经验与道德的权威。

然而随科学技术的发展和村民职业的分化,村落中许多过去的经验因陈旧失去了其传承的价值,而善于接受新事物的年轻一代,能力日渐显现。

乡村社会中的年长者,在乡村文化秩序中的权威地位渐渐弱化,在家庭成员中的角色慢慢被边缘化,使乡村传统文化中的核心——礼俗文化受到了挑战。

与此同时,经济日益成为乡村生活的强势话语,利益标准取代了传统文化中蕴含的道德评价标准,乡村传统文化的内涵和价值渐渐地被隐匿。

表现在实际生活中,尊老爱幼、与人为善、以和为贵等道德观逐渐被相互提防、唯利是图和以自我为中心等价值观所代替,一些村民变得越来越短视和趋利。

③正确的价值观能润滑社会关系,促进社会和谐。

然而,伴随乡村村民与外界交往的增多,传统乡村社会所崇尚的诚实、淳朴意识及热情好客、重义轻利的朴实做法遭遇了复杂的现代社会中敲诈勒索、坑蒙拐骗、见利忘义和竞争优胜劣汰的残酷现实。

在乡村社会传统的道德范式正逐渐落寞、而新的道德范式却没有真正建立起来的情形下,村民自身无法有效抵御各种负面冲击,常常只会依据自己的现实利益行动。

当看到朴实厚道并不被人看作是美德,坚守传统并不能使自己获利,而身边一些人投机取巧、凶狠霸道甚至损人利己却获得利益并引人称羡的时候,很多恪守传统礼俗道德的村民陷入了迷惘。

She told the children on the first day that she loved them all the same. But that was a lie. There in the front row was a little boy named Teddy Stoddard. He did n’t play well with the other children and he always needed a bath. She did not like him.Then Mrs. Thompson got to know that Teddy was actually a very good boy before the death of his mother. Mrs. Thompson was ashamed of herself. She felt even worse when, like all her other students, Teddy brought her a Christmas present too. It was his mother’s perfume. Teddy said, “Mrs. Thompson, today you smell just like my Mom used to.” After the children left she cried for at least an hour. On that very day, she stopped teaching reading, writing and math. Instead, she began to teach children.Mrs. Thompson paid particular attention to Teddy. The boy’s mind seemed to come alive. The more she encouraged him, the faster he improved. By the end of the sixth grade, Teddy had become one of the smartest children in the class.Six years went by before she got a note from Teddy. He wrote that he had finished high school, third in his class, and she was still the best teacher he ever had in his whole life. He went to college. Mrs. Thompson got two more letters from him with the last one signed, Theodore F. Stoddard, M. D.(医学博士).The story doesn’t end there. On his wedding day, Dr. Stoddard whispered in Mrs. Thompson’s ear, “Thank you, Mrs. Thompson, for believing in me. You made me feel important and showed me that I could make a difference.”Mrs. Thompson, with tears in her eyes, whispered back, “Teddy, you have it all wrong. You were the one who taught me that I could make a difference. I didn’t know how to teach until I met you.”21. What did Mrs. Thompson do on the first day of school?A. She made Teddy feel ashamed.B.
