As is commonly acknowledged / It is commonly recognised that humans are social animals. Bonded together in a community, we naturally expect to have friends. As to what friendship is, people have different notions / ideas. Some make friends for mutual utility. Once the ground for such friendship disappears, the friendship also breaks up. However, a lot more people long for "soul pals"— those who possess virtues and with whom we can go through trials and tribulations together. Such friendships keep us away from greed and violence and encourage us to have the courage of our convictions. Such is what we call "true and perfect friendship".
1. Bob and I became brother-like friends in our childhood. We played, dined and discussed our ambitions together. Once grown up, he started for the West to make his fortune while I became a policeman in New York. Before his departure, we had dinner together and we agreed that we would meet at the same place exactly twenty years from that date and time, no matter what our
conditions might be or from what distance we might have to come.
Then came the day we were supposed to meet. I was on my beat then. Walking up to the appointed place which had been turned into a hardware store, I saw a man standing there with an unlighted cigar in his mouth. Before I could speak, he told me that he was waiting for a friend by the name of Jimmy Wells. When he struck a match to light his cigar, I saw a pale face with keen eyes and a scar. I recognized him immediately. It was Bob, and it was also the face of the man wanted by the Chicago Police.
For a moment I felt like telling him to escape right away. After all, we had been friends for so many years and he had traveled all the way to see me! But then my sense of duty told me the right thing to do. I said good-bye to him and continued my patrol, his last words still ringing in my ear: “I’ll wait for half an hour. Jimmy will keep his promise if he’s alive…” I then sent for
a plain clothes man and had Bo
b arrested.
2.An Important Friend in My Life
Li Qiang, one of my classmates, is fun to be with. He is always wearing a broad smile as if life is forever "sunshine and
butterflies". One day, I revealed to him my worries and anxieties:
I, an ordinary-looking girl, was 177 centimeters tall, even taller than any of the boys in my class. I thought no boy would like to date me. Besides, I was very poor at my academic courses.
He suggested that I should learn to be myself and then he introduced me to a fashion show team of the university. Encouraged, I decided to change myself. After a 3-month training program on weekends, I could perform beautifully as a model, and surprisingly, I could concentrate on the required academic courses as well. The applauses I won at each fashion show and the scholarship I earned proved that being myself was terrific. Since then, my life has changed a lot. Thus, Li Qiang became an important friend of mine.
Last semester, we began to help young people who suffer pressures from physical defects, academic failures or financial problems. We set up a Confidence Club. Those who come to us for help find our work definitely beneficial. Our friendship has led me into a sparkling, rewarding life.

After dinner, we all sat around the hearth. Aunt Susan was still in the grief of losing Uncle Robert. In her soft voice she told us about their past years. Uncle Robert joined the army shortly after they were engaged. Given the critical situation at the time when lots of army men didn’t return alive, you can imagine how much overjoyed Aunt Susan was to see Uncle Robert come back safe and sound from the European battlefield. Then they got married and brought up five children. For all those years, their affection for each other grew stronger in the course of overcoming difficulties and hardships in life. I was fascinated by Aunt Susan’s s tory, which was totally different from my ideal of love. They practiced giving and sharing in their daily life instead of pursuing passion and romance. Amazingly, such love lasted through their whole life.
1. Male-female relations are indispensable to adults all through their lives. But different generations handle them differently. Our parents’ generation lived in an era of constraints, restraints, respect, admiration, and plenty of romance. They kept
a distance from people of the opposite gender in order to preserve the holiness of love and relationships.
My generation, on the other hand, began with countless crushes for the opposite sex just because of their superficial charm. Harmless as it was, the love was as brief as soap bubbles. As we grew up, we came to the stage of developing real relationships, believing that love demanded a lot of give and not so much of take.
By comparison, the younger generation is more open-minded and less restricted in handling the matter of love and relationships. They jump on the bandwagon of love with so much haste that it is difficult for them to distinguish between physical attraction and mental compatibilities.
In short, the younger generation focuses more on physical beauty, closeness and passion, and they tend to seek what they want from the relationships. The other two generations give priority to inner charm, intimacy, emotion and sharing in dealing with relationships.
2.What Do Girl Students Look for in Love and Life?
In order to know about girl students’ opinion about love and life, a survey with girl students was conducted in 2005 in two universities — Chongqing University of Technology and
Business and East China Normal University. The survey sought answers to two questions: What do you look for first in a boyfriend? What’s the most important thing for a happy life? About one third of the students chose personality as the top factor in choosing a boyfriend, followed by 27 percent focusing on abilities. Next came common interests and goals, favoured by 17 percent, with only 14 percent of students claiming appearance
to be uppermost in their minds. Fewer still, 11 percent, rated economic status as the first consideration.
As to their views about a happy life, nearly seventy percent of the girls attached the greatest importance to marriage and family.
“Career” was given top priority by just under 20 percent, while even fewer, around 9 percent, believed that money was the key to a happy life.
Based on the survey, we may conclude that nowadays, girl students generally hold a rational attitude towards love and life. Admittedly, the improved material conditions of life explain why girls take economic status and money rather lightly. But contrary to the popular view that girls are more concerned about self-development in the workplace and social status, they still
regard upon marriage and family life as central to a happy life.

大学物理实验课后习题答案
一牛顿环的各环是否等宽?密度是否均匀?解释原因? 因为环是由空气劈上下表面反射的两束光叠加干涉形成的。劈的上表面变化在横向是不均匀的，故光程差也不是均匀变化的。所以各环是不等宽的环的密度也不是均匀的。各环不等宽，半径小的环宽，越到外边越窄，密度是不均匀的,牛顿环的半径公式是：半径r等于根号下(m+1/2)λR，其中m为环的级数。从公式可以看出，半径和环数并不是线性关系，这样环自然不均匀。计算可以知道，越往外环越密。 二牛顿环的干涉圆环是由哪两束相干光干涉产生的? 半凸透镜下表面和下底面上表面的两束反射光 三电桥由哪几部分组成?电桥平衡的条件? 由电源、开关、检流计桥臂电阻组成。 平衡条件是Rx=(R1/R2)R3 四接通电源后,检流计指针始终向一边偏转,试分析出现这种情况的原因? 指针向一侧偏转就说明发生了电子的定向移动了，这个应该没问题。 指针不偏转，有2种情况吧，其1呢是整个电路发生了断路或其他故障，还1种情况则是流过的电流太小，不足于使电表发生偏转或其偏转的角度肉眼根本看不到。 无论如何调节，检流计指针都不动，电路中可能出现故障是调节臂电阻断路或短路。。无论如何调节，检流计指针始终像一边偏而无法平衡，电路中有可能出现故障是有一个臂（非调节臂）的电阻坏了。（断路或短路） 五什么叫铁磁材料的磁滞现象? 铁磁物质经外磁场磁化到饱和以后，把磁场去掉。这些物质仍保留有剩余磁化强度。需要反方向加磁场才能把这剩余磁化强度变为零。这种现象称为铁磁的磁滞现象。也是说，铁磁材料的磁状态，不仅要看它现在所处的磁场条件；而且还要看它过去的状态。 六如何判断铁磁材料属于软.硬材料? 软磁材料的特点是：磁导率大，矫顽力小，磁滞损耗小，磁滞回线呈长条状；硬磁材料的特点是：剩磁大，矫顽力也大 用光栅方程进行测量的条件是什么? 条件是一束平行光垂直射入光栅平面上，光波发生衍射，即可用光栅方程进行计算。如何实现：使用分光计，光线通过平行光管射入，当狭缝位于透镜的焦平面上时，就能使射在狭缝上的光经过透镜后成为平行光 用光栅方程进行测量,当狭缝太窄或者太宽会怎么样?为什么? 缝太窄，入射光的光强太弱，缝太宽，根据光的空间相干性可以知道，条纹的明暗对比度会下降！ 区别是，太窄了，亮纹会越来越暗，暗纹不变，直到一片黑暗！ 太宽，暗条纹会逐渐加强，明纹不变，直到一片光明！

大学物理实验课后答案
实验一霍尔效应及其应用 【预习思考题】 1．列出计算霍尔系数、载流子浓度n、电导率σ及迁移率μ的计算公式，并注明单位。 霍尔系数，载流子浓度，电导率，迁移率。 2．如已知霍尔样品的工作电流及磁感应强度B的方向，如何判断样品的导电类型？ 以根据右手螺旋定则，从工作电流旋到磁感应强度B确定的方向为正向，若测得的霍尔电压为正，则样品为P型，反之则为N型。 3．本实验为什么要用3个换向开关？ 为了在测量时消除一些霍尔效应的副效应的影响，需要在测量时改变工作电 流及磁感应强度B的方向，因此就需要2个换向开关；除了测量霍尔电压，还要测量A、C间的电位差，这是两个不同的测量位置，又需要1个换向开关。总之，一共需要3个换向开关。 【分析讨论题】 1．若磁感应强度B和霍尔器件平面不完全正交，按式（5.2-5）测出的霍尔系数比实际值大还是小？要准确测定值应怎样进行？ 若磁感应强度B和霍尔器件平面不完全正交，则测出的霍尔系数比实际值偏小。要想准确测定，就需要保证磁感应强度B和霍尔器件平面完全正交，或者设法测量出磁感应强度B和霍尔器件平面的夹角。 2．若已知霍尔器件的性能参数，采用霍尔效应法测量一个未知磁场时，测量误差有哪些来源？ 误差来源有：测量工作电流的电流表的测量误差，测量霍尔器件厚度d的长度测量仪器的测量误差，测量霍尔电压的电压表的测量误差，磁场方向与霍尔器件平面的夹角影响等。 实验二声速的测量 【预习思考题】 1. 如何调节和判断测量系统是否处于共振状态？为什么要在系统处于共振的条件下进行声速测定？ 答：缓慢调节声速测试仪信号源面板上的“信号频率”旋钮，使交流毫伏表指针指示达到最大（或晶体管电压表的示值达到最大），此时系统处于共振状态，显示共振发生的信号指示灯亮，信号源面板上频率显示窗口显示共振频率。在进行声速测定时需要测定驻波波节的位置，当发射换能器S1处于共振状态时，发射的超声波能量最大。若在这样一个最佳状态移动S1至每一个波节处，媒质压缩形变最大，则产生的声压最大，接收换能器S2接收到的声压为最大，转变成电信号，晶体管电压表会显示出最大值。由数显表头读出每一个电压最大值时的位置，即对应的波节位置。因此在系统处于共振的条件下进行声速测定，可以容易和准确地测定波节的位置，提高测量的准确度。 2. 压电陶瓷超声换能器是怎样实现机械信号和电信号之间的相互转换的？ 答：压电陶瓷超声换能器的重要组成部分是压电陶瓷环。压电陶瓷环由多晶结构的压电材料制成。这种材料在受到机械应力，发生机械形变时，会发生极化，同时在极化方向产生电场，这种特性称为压电效应。反之，如果在压电材料上加交

JSP的两种体系结构是：______________和______________。 3. JSP开发Web站点的主要方式有：直接JSP、JSP+JavaBean、______________、______________和SSH。 参考答案： 1.JSP 2.JSP Model1和JSP Model2 3.JSP+JavaBean+Servlet、J2EE/JavaEE 1.7.3 简答题 1. 简述JSP的工作原理。 答：所有的JSP应用程序在首次载入时都被翻译成Servlet文件，然后再运行，这个工作主要是由JSP引擎来完成。当第一次运行一个JSP页面时，JSP引擎要完成以下操作： ●将JSP文件翻译成Servlet文件，Servlet文件是Java应用程序。 ●JSP引擎调用Java编译器，编译Servlet文件得到可执行的代码文件（.class文件）。 ●JSP引擎调用Java虚拟机解释执行.class文件，并将运行结果返回给服务器。 ●服务器将运行结果以HTML形式作为响应返回给客户端的浏览器。 由于一个JSP页面在第一次被访问时要经过翻译、编译和执行这几个步骤，所以客户端得到响应所需要的时间比较长。当该页面再次被访问时，它对应的.class文件已经生成，不需要再次翻译和编译，JSP引擎可以直接执行.class文件，因此JSP页面的访问速度会大为提高。 2. 简述JSP两种体系结构。

大学物理实验课后答案
（1）利用f=(D+d)(D-d)/4D 测量凸透镜焦距有什么优点？ 答这种方法可以避免透镜光心位置得不确定而带来得测量物距与像距得误差。 （2）为什么在本实验中利用1/u+1/v=1/f 测焦距时，测量u与v都用毫米刻度得米尺就可以满足要求？设透镜由于色差与非近轴光线引起得误差就是1％。 答设物距为20cm，毫米刻度尺带来得最大误差为0、5mm，其相对误差为 0、25％，故没必要用更高精度得仪器。 （3）如果测得多组u，v值，然后以u+v为纵轴，以uv为横轴，作出实验得曲线属于什么类型，如何利用曲线求出透镜得焦距f。 答直线；1/f为直线得斜率。 （4）试证：在位移法中，为什么物屏与像屏得间距D要略大于4f？ 由f=(D+d)(D-d)/4D →D2-4Df=d2→D(D-4f)=d2 因为d>0 and D>0 故 D>4f 1、避免测量u、ν得值时，难于找准透镜光心位置所造成得误差。 2、因为实验中，侧得值u、ν、f都相对较大，为十几厘米到几十厘米左右，而误差为1%，即一毫米到几毫米之间，所以可以满足要求。 3、曲线为曲线型曲线。透镜得焦距为基斜率得倒数。 ①当缝宽增加一倍时,衍射光样得光强与条纹宽度将会怎样变化?如缝宽减半,又怎样改变? 答: a增大一倍时, 光强度↑；由a=Lλ/b ，b减小一半 a减小一半时, 光强度↓；由a=Lλ/b ，b增大一倍。 ②激光输出得光强如有变动,对单缝衍射图象与光强分布曲线有无影响?有何影响? 答:由b=Lλ/a、无论光强如何变化,只要缝宽不变,L不变,则衍射图象得光强分布曲线不变(条纹间距b不变)；整体光强度↑或者↓。
③用实验中所应用得方法就是否可测量细丝直径？其原理与方法如何？ 答：可以，原理与方法与测单狭缝同。 ④本实验中，λ=632。8nm ,缝宽约为5*10^-3㎝,屏距L 为50㎝。试验证： 就是否满足夫朗与费衍射条件？ 答：依题意： L λ=（50*10^-2）*（632、8*10^-9）=3、164*10^-7 a^2/8=(5*10^-5)^2/8=3、1*10^-10 所以L λ<
