We see money almost every day. Parents give us pocket money. We pay for what we want with money. We can hardly imagine what our life will be like without money. Money helps people trade. If you want a kilo of chicken, you don't have to give the seller a box of apples or something else. You can just use money.

We usually have two kinds of money, coins (硬币）and banknotes（纸币). Each country has its own money. Some have their leaders’ faces on the coins and banknotes, some have plants or animals, others have beautiful or historical places on the fronts or backs of the money. So you see, money also says something about the culture of a country.

China has five sets of banknotes. Today only the fifth and the fourth sets can be used. On the fronts of the fifth set of banknotes there is the face of Chairman Mao Zedong. On the back there are different scenes. They show that China is a big and beautiful country. If you look carefully, you'll see characters(文字,符号) from the languages of different minority groups（少数民族）on the back.

A. 旅游

B. 对待

D. 工作

B. a pen

C. a lion

D.

a flower

56. How many sets of banknotes can we Chinese use now?

A. Two

B. Four

C. Five

D. Seven

57. What’s the main idea of the passage?

D. The use of money and the kinds of money.

Look at the center circles of Diagram (图)A and Diagram

B.

Which of the centre circles looks larger?

Take a first look and you probably think that the centre circle

in Diagram A is smaller than that in Diagram B. In fact, they are

exactly the same size.

vase （花

瓶）? Or two faces ？Does the picture change quickly from one to the

other again and again? Maybe yes or maybe no, but you can never

see

them at the same time.

“What’s happening? Is something wrong with my eyes?” You may

wonder at what you see. Don’t worry. Here is how it goes:

When we look at things, our eyes send messages to our brains and then our brains

interpret （解读）the information. However, sometimes our brains interpret the received information in a wrong way. It seems that our eyes are playing a joke on us. This often happens and we call it “Visual illusion（视觉错误）”.

Movie makers often make use of illusions. They make the objects around actors

much smaller or bigger than usual. This makes us believe that the actors are much larger or smaller than they usually are. The movies Jurassic Park and Honey I shrunk the kids just make use of illusions. 58. The text is probably taken from . A. a story book B. a science book

C. a movie magazine

D. an advertisement

59. The centre circle in Diagram A looks smaller than that in Diagram B. That’s because .

A. something is wrong with our eyes

than Line CD, but in fact Line AB is as long as Line CD.

The ________paragraph(段落) can explain this.

A. second

B. third

A B C D

A B

C. fifth

D. sixth

( D )

Now throwing shoes at President Bush is a popular game on the Internet. It turns out that there are times when it’s good to throw shoes.

重庆巴蜀中学 关于开展校本课程总结表彰及等级评定的通知各位校长、各位老师： 为了调动学校广大教职工积极参与新课程改革，开发校本课程，促进学校办出特色，促进教师专业发展；也为了整理、总结学校开展校本课程建设的成果，不断提高教师、学校实施校本课程建设的能力，经学校研究，决定自2011年起，每年进行一次校本课程建设总结表彰。现将《巴蜀中学校本课程评价方案》（见附一）公布于此，并对校本课程等级申报、评定工作，做如下部署，请各位老师参照执行。 1、凡是参与过高2011级高一（下）选修课程开设（具体课程名称及指导教师姓名，见附三）的教师及课程；凡是参与过高2013级高一（下）选修课程开设（具体课程名称及指导教师姓名，见附四）的教师及课程，因相关资料在学校已有存档，故相关课程教师，可以不再提交资料及填写申报表，学校组织专家组根据学校已有资料进行评审。 2、学校除高2011级、高2013级外，在其他年级开设过选修课的老师，或附 3、附4有遗漏、错误的教师，请将开课的相关材料进行整理，于7月29日以前将纸质材料，课程等级申报表（见附二）交到本部行政楼二楼课改处。或发往bashu_zhang@https://www.sodocs.net/doc/214039862.html,。逾期不予受理申报申请。 重庆巴蜀中学 2011年7月21日

附一： 巴蜀中学校本课程评价方案 （试行） 一、指导思想及评价原则 落实学校教育理念。校本课程开设要符合学校“教育以人为本，校长以教师为本，教师以学生为本”的教育理念，发现和发展学生的潜能，促进学生全面发展和个性成长，引领教师多元发展。 贯穿学校德育主线。校本课程必须体现学校的“善为根、雅为骨、志为魂”的育人理念，校本课程评价必须依托“公正诚朴”的校训，提升学生对“善雅志”的感悟，培养紧跟时代主旋律的合格中学生。 彰显区域发展特色。校本课程在“131”校本课程体系内，教师可以选择自己认为合适的任何内容来设计课程，但课程的选择要体现学校的办学特色及学校所在区域的政治、经济、文化、社会等各方面实际情况，体现区域发展特色。 把握时代发展脉搏。校本课程的提出和教学内容设计必须符合时代发展的特征，扎根经济、政治、文化和社会的丰厚土壤，尽量体现经济发展的方向、政治民主法治建设进程、文化发展的趋势和社会发展的热点。总之，校本课程要引领时代发展潮流。 坚持科学发展思路。校本课程是在国家课程基础上的拓展，学生能否实现知识、能力、视野的拓展，能否实现情感、态度、价值观的感悟是评价校本课程实施成效的重要内容。因此，校本课程的开发必须与国家课程相一致，与学生身心特点相适应，与学生的兴趣爱好相一致，帮助学生认识科学规律、接受人文熏陶。 二、评价策略

2 B g a = B 正确； C ．根据正电荷的电场分布可知，B 点更靠近点电荷，所以B D 段的平均场强大小大于AD 段的平均场强，根据U Ed =可知，BD 之间的电势差U BD 大于DA 之间的电势差U DA ，C 正确； D ．由A 点到B 点，根据动能定理得 sin 02 AB L mg θqU ? += 由2 sin A Qq mg k ma L θ-=可得 214Qq mg k L = 联立上式解得 AB kQ U L =- D 错误。 故选BC 。 2．电荷量相等的两点电荷在空间形成的电场有对称美．如图所示，真空中固定两个等量异种点电荷A 、B ，AB 连线中点为O.在A 、B 所形成的电场中，以O 点为圆心半径为R 的圆面垂直AB 连线，以O 为几何中心的边长为2R 的正方形平面垂直圆面且与AB 连线共面，两个平面边线交点分别为e 、f ，则下列说法正确的是( ) A ．在a 、b 、c 、d 、e 、f 六点中找不到任何两个场强和电势均相同的点 B ．将一电荷由e 点沿圆弧egf 移到f 点电场力始终不做功 C ．将一电荷由a 点移到圆面内任意一点时电势能的变化量相同 D ．沿线段eOf 移动的电荷，它所受的电场力先减小后增大 【答案】BC 【解析】 图中圆面是一个等势面，e 、f 的电势相等，根据电场线分布的对称性可知e 、f 的场强相同，故A 错误．图中圆弧egf 是一条等势线，其上任意两点的电势差都为零，根据公式W=qU 可知：将一正电荷由e 点沿圆弧egf 移到f 点电场力不做功，故B 正确．a 点与圆面内任意一点时的电势差相等，根据公式W=qU 可知：将一电荷由a 点移到圆面内任意一点时，电场力做功相同，则电势能的变化量相同．故C 正确．沿线段eof 移动的电荷，电场

重庆重庆市巴蜀中学校圆周运动专题练习(解析版)

一、第六章 圆周运动易错题培优（难） 1．两个质量分别为2m 和m 的小木块a 和b （可视为质点）放在水平圆盘上，a 与转轴OO ’的距离为L ，b 与转轴的距离为2L ，a 、b 之间用强度足够大的轻绳相连，木块与圆盘的最大静摩擦力为木块所受重力的k 倍，重力加速度大小为g ．若圆盘从静止开始绕转轴缓慢地加速转动，开始时轻绳刚好伸直但无张力，用ω表示圆盘转动的角速度，下列说法正确的是（ ） A ．a 、b 所受的摩擦力始终相等 B ．b 比a 先达到最大静摩擦力 C ．当2kg L ω=a 刚要开始滑动 D ．当23kg L ω=b 所受摩擦力的大小为kmg 【答案】BD 【解析】 【分析】 【详解】 AB ．木块随圆盘一起转动，静摩擦力提供向心力，由牛顿第二定律可知，木块受到的静摩擦力f =mω2r ，则当圆盘从静止开始绕转轴缓慢地加速转动时，木块b 的最大静摩擦力先达到最大值；在木块b 的摩擦力没有达到最大值前，静摩擦力提供向心力，由牛顿第二定律可知，f=mω2r ，a 和b 的质量分别是2m 和m ，而a 与转轴OO ′为L ，b 与转轴OO ′为2L ，所以结果a 和b 受到的摩擦力是相等的；当b 受到的静摩擦力达到最大后，b 受到的摩擦力与绳子的拉力合力提供向心力，即 kmg +F =mω2?2L ① 而a 受力为 f′-F =2mω2L ② 联立①②得 f′=4mω2L -kmg 综合得出，a 、b 受到的摩擦力不是始终相等，故A 错误，B 正确； C ．当a 刚要滑动时，有 2kmg+kmg =2mω2L +mω2?2L 解得 34kg L ω＝
