2、传统文化对大学生饰品消费的影响
木质、石质、骨质、琉璃、藏银……一颗颗、一粒粒、一片片,都浓缩了自然之美,展现着千种风情、万种诱惑,与中国结艺的朴实形成了鲜明的对比,代表着欧洲贵族风格的饰品成了他们最大的主题。
自制饰品一反传统的饰品消费模式,引导的是一种全新的饰品文化,所以非常容易被我们年轻的女生接受。
培养动手能力□ 学一门手艺□ 打发时间□ 兴趣爱好□因此不难看出,自制饰品在校园里也大有市场所在。对于那些走在流行前端的女生来说,〝捕捉〞新事物便〝捕捉〞到了时尚与个性。
尽管售价不菲,但仍没挡住喜欢它的人来来往往。这里有营业员们向顾客们示范着制作各种风格迥异的饰品,许多顾客也是学得不亦乐乎。在现场,有上班族在里面精挑细选成品,有细心的小女孩在仔细盘算着用料和价钱,准备自己制作的原料。可以想见,用本也许正是自己制造所能带来最大的快乐吧。

Reading comprehensionAMany people go to school for an education. They learn languages, history, geography, physics, chemistry and mathematics. Others go to school to learn a skill so that they can make a living. School education is very important and useful. Yet no one can learn everything from school. A teacher, no matter how much he knows cannot teach his students everything they want to know. The teacher’s job is to show his students how to learn. Heteaches them how to read and how to think. So much more is to be learned outside school by the students themselves.It is always more important to study by oneself that to memorize some facts or a formula (公式). It is2actually quite easy to learn a certain fact in history or a formula in math. But it is very difficult to use a formula in working out a math problem. Great scientists, such as Einstein, Newton and Galileo didn’t get everything fromschool. But they were all so successful. They invented so manythings for mankind. The reason for their success is that they worked hard all their lives, wasting not a single moment. They would ask many questions as they read and they did thousands of experiments.Above all, they knew how to use their brains.1. The subject which is not spoken of in the article is _________.A. mathB. historyC. physiologyD. physics2. The teacher’s job is to reach __________.A. everything the students want to knowB. the students everything that they knowC. the students some facts of formulasD. the students how to learn3. Einstein, Newton and Galileo did so many things for mankind because __________.A. they learned a lot at schoolB. they knew how to learn new things outside class by themselvesC. they were so usefulD. they went to college and learned from professors4. From the passage we know that if we want to be successful, we should ___________.A. only learn more at schoolB. needn’t go to schoolC. only learn science subjectsD. learn to learn at school and learn more outside schoolBFrance has been one of the main pioneers of many forms of artistic expression throughout its history. France and art are strongly connected with each other, and it would not be possible to think of world art without thinking of France.The importance of art in France can be easily seen by the great number of museums and art exhibitions throughout the country. They include the Musee du Louvre, which is one of the greatest museums of the world. There is also the Musee du Moyen Age in this list, which exhibits medieval artworks, and the Centre Pompidou, exhibiting art from the twentieth century. Among other important museums and exhibitions are the Musee d’Orsay,where visitors can observe a collection of French art from the 20th century, and the Musee Picasso, which exhibits amazing artworks fromthis outstanding artist. The Musee Rodin is another great place to visit in order to enjoy French art and to observe some amazing sculptures from this artist.The relation between France and art can be traced back to as long ago as the Stone Age. Many artworks dating from this period have been found in France and provide unique information about the culture and art of the world. In France, each time was strongly connected with art andhad its own art expression forms and characteristics, and they were closely connected with French history and culture.36. We can learn from the first paragraph that _____________.A. France is famous for its artB. France has the greatest museum of the worldC. French art plays an important role in world artD. France has the largest number of famous artists37. How many museums are mentioned in the passage in total?A.4.B.5.C.6.D.7.38. If you want to observe some amazing sculptures, which of the following places should you visit?A. The Musee d'Orsay.B. The Musee du Moyen Age.C. The Centre Pompidou.D. The Mus6e Rodin.39. It is implied in the last paragraph that _____________.A. France has the longest history of art in the world3B. artworks from the Stone Age are the most valuableC. French people now don't think art is important in their livesD. in France different periods of time have different styles of art40. In which section of a newspaper would you most probably readthis passage?A. Business.B. Education.C. Art.D. GeographyCIf there is one thing I'm sure about, it is that in a hundred years from now we will still be reading newspapers. Now some people get mostof their news from television or radio. Many buy a newspaper only on Saturday or Sunday. But for most people reading a newspaper has become a habit passed down from generation to generation.The nature of what is news may change. What basically makes news is what affects our lives-the big political stories, the coverage of the wars, earthquakes and other disasters, will continue much the same. I think there will be more coverage of scientific researches, though. It's already happening in areas that may directly affect our lives, like genetic engineering. In the future, I think there will be more coverage of scientific explanations of why we feel as we do-as we develop abetter understanding of how the brain operates and what our feelings really are.It's quite possible that in the next century newspapers will be transmitted (传递) electronically from FleetStreet and printed out in our own homes. In fact, I'm pretty surehow it will happen in the future. You will probably be able to choose from a menu, making up your own newspaper by picking out the things you want to read----sports and international news, etc.I think people have got it wrong when they talk about thecompetition among the different media. They actually feed off each other. It was once predicted that television would kill off newspapers, butthat hasn't happened. What is read on the printed page lasts longer thanpictures on a screen or sound lost in the air. And as for the Internet,it's never really pleasant to read something just on a screen.41. What is the best title for the passage?A. The Best Way to Get NewsB. The Changes of MediaC. Make Your Own NewspapersD. The Future of Newspapers42. In the writer's opinion, in the future, ______________.A. more big political affairs, wars and disasters will make newsB. newspapers will not be printed in publishing houses any longerC. newspapers will cover more scientific researchesD. more and more people will watch TV43. What will probably be on in the newspaper made by yourself?A. Sports and international news.B. A menu of important news.C. The most important news.D. What you are interested in.44. From the passage, we can infer ______________.A. newspapers will win the competition among the different mediaB. newspapers will stay with us together with other mediaC. television will take the place of newspaperD. the writer believes some media will die out45. The phrase "feed off" in the last paragraph means ______________.A. supportB. divideC. separateD. break up4。

最新成都实验外国语直升试题(题卷)答案ding

成都市实验外国语学校2012年直升生考试数学试题一、选择题(每小题4分,共40分,请将正确答案填入表格中) 1、多项式225441225x xy y x -+++的最小值为( )A 、4B 、5C 、16D 、25 解析:5x²-4xy+4y²+12x+25 =x²+4x²-4xy+4y²+12x+25 =(x²-4xy+4y²)+4(x²+3x+2.25)+16 =(x-2y)²+4(x+1.5)²+16 ∵(x-2y )²≥0,(x+1.5)²≥0 ∴(x -2y)²+4(x+1.5)²+16≥16 (当且仅当x-2y=0,x+1.5=0,即x=-1.5,y=-0.75时取到最小值) ∴多项式5x²-4xy+4y²+12x+25的最小值为162、若函数212y x x c=++的自变量x 的取值范围为一切实数,则c 的取值范围是( ) A 、1c < B 、1c = C 、1c > D 、1c ≤解析:由题意得:x^2+2x+c 恒不等于零,又因为系数是大于零的,所以有:判别式是小于零的,即:4-4c<0,即c>13、在锐角ABC ∆中,已知某两边1,3a b ==,那么第三边c 的变化范围是( c ) A 、24c << B 、23c <≤ C、2c << Dc <<解析:已知三角形锐角ABC 所以A+B>C(三角形两边之和大于第三边) 所以C<1+3 C<4 从顶点A 做一条垂线,垂足为D 构造RT 三角形ADB.由勾股定理得 AD^2=AB^2-BD^2 =1-4 =-根号3 再算另一个RT 三角形得出 2<C<根号10 4、已知1O 的半径为3cm ,2O 的半径为7cm ,若12,O O 的公共点不超过一个,则两圆的圆心距不可能是( C )A 、0cmB 、4cmC 、8cmD 、12cm5、已知a 是实数,且关于x 的二次方程220x a x a ++=有实根,则该方程的根x 所能取的最大值是( )A 、0 B、、2 D、2解析:把x^2+a^2x+a = 0看成关于a的二元一次方程 即,xa^2+a+x^2=0 因为,a 为实数所以,方程xa^2+a+x^2=0有实根 则,Δ=1-4x^3≥0x≤3^√(1/4) 即3√2/26、方程227(13)20x k x k k -++--=(k 是常数)有实根,αβ,且01,12αβ<<<<,那么k 的范围是( )A 、34k <<B 、21k -<<-C 、2134k k -<<-<<或D 、无解 f(x)=7x^2-(k+13)x+k^2-k-2 抛物线开口向上 作图可知 充要条件: f(0)>0 k^2-k-2>0 k<-1或k>2 f(1)<0 k^2-2k-8<0 -2<k<4 f(2)>0 k^2-3k>0 k<0或k>3 不等式组解 -2<k<-1或3<k<47、已知抛物线224(03)y ax ax a =++<<,1122(,),(,)A x y B x y 是抛物线上两点,若12x x <,且121x x a +=-,则( )A 、12y y <B 、12y y =C 、12y y >D 、12,y y 大小无法确定 解:将A 点代入方程得:Y1=AX1^2+2AX1+4,① 将B 点代入方程得:Y2=AX2^2+2AX2+4,② ①-②得:Y1-Y2=A (X1+X2)(X1-X2)+2A (X1-X2)=A (X1-X2)(X1+X2+2)=A (X1-X2)(3-A )∵x1<x2,0<A<3,∴3-A >0,∴A (X1-X2)(3-A )<0,∴Y1<Y28、锐角ABC ∆的三边两两不等,D 是BC 边上一点,90BAD C ∠+∠=︒,则AD 一定过ABC ∆的( )A 、重心B 、内心C 、外心D 、垂心外心; 作辅助线,延长ad 到e 使∠dce=∠bad,于是∠ace=90°,从而ae 就是三角形abc 外接圆的直径,ae 的中点即外心在ad 上,所以ad 一定过三角形abc 的外心9、一个一次函数的图像与直线59544y x =+平行,与x 轴、y 轴的交点分别是,A B ,并且过点(1,25)--,则在线段AB 上(包括端点,A B ),横、纵坐标均为整数的点有( )个A 、4个B 、5个C 、6个D 、7个由y=ax+b 与y=(5/4)x+95/4平行, ∴a=5/4,得y=(5/4)x+b , 将(-1,-25)代入: -25=-5/4+b ,b=-95/4 得:y=(5/4)x+95/4. 当y=0,x=-19,∴A (-19,0) 当x=0,y=95/4,∴B (0,95/4) ∵y=(5/4)x+95/4 =(5x+95)/4 当5x+95是4的整倍数时, 即x=-3,-7,-11,-15,-19时 y=20,15,10,5,0 共有5个点(-3,20)(-7,15)(-11,10)(-14,5)(-19,0)。
