顾晓珺一:《追风筝的人》好句好段汇总
I became what I am today at the age of twelve, on a frigid overcast day in the winter of 1975. I remember the precise moment, crouching behind a crumbling mud wall, peeking into the alley near the frozen creek. That was a long time ago, but it�s wrong what they say about the past, I�ve learned, about how you can bury it. Because the past claws its way out. Looking back now, I realize I have been peeking into that deserted alley for the last twenty-six years.
Ch. 1
Ali and Sanaubar had little in common, least of all their respective appearances. While Sanaubar�s brilliant green eyes and impish face had, rumor has it, tempted countless men into sin, Ali had a congenital paralysis of his lower facial muscles, a condition that rendered him unable to smile and left him perpetually grim-faced. It was an odd thing to see the stone-faced Ali happy, or sad, because only his slanted brown eyes glinted with a smile or welled with sorrow. People say that eyes are windows to the soul. Never was that more true than with Ali, who could only reveal himself through his eyes.
I have heard that Sanaubar�s suggestive stride and oscillating hips sent men to reveries of infidelity.
Ch. 2
Then he would remind us that there was a brotherhood between people who had fed from the same breast, a kinship that not even time could break.
Hassan and I fed from the same breasts. We took our first steps on the same lawn in the same yard. And, under the same roof, we spoke our first words.
Mine was Baba.
His was Amir. My name.
Looking back on it now, I think the foundation for what happened in the winter of 1975�"and all that followed�"was already laid in those first words (11).
Ch. 2
Children aren"t coloring books. You don"t get to fill them with your favorite colors.- Rahim Khan
Ch. 3
With me as the glaring exception, my father molded the world around him to his liking. The problem, of course, was that Baba saw the world in black and white. And he got to decide what was black and what was white. You can"t love a person who lives that way without fearing him too. Maybe even hating him a little.
If America taught me anything, it"s that quitting is right up there with pissing in the Girl Scouts" lemonade jar.
There is only one sin, only one. And that is theft. Every other sin is a variation of theft....When you kill a man, you steal a life. You steal his wife"s right to a husband, rob his children of a father. When you tell a lie, you steal someone"s right to the truth. When you cheat, you steal the right to fairness.
One time, when I was really little, I climbed a tree and ate these green, sour apples. My stomach swelled and became hard like a drum, it hurt a lot. Mother said that if I"d just waited for the apples to ripen, I wouldn"t have become sick. So now, whenever I really want something, I try to remember what she said about the apples.
I wondered if that was how forgiveness budded, not with the fanfare of epiphany, but with pain gathering its things, packing up, and slipping away unannounced in the middle of the night.
I think that everything he did, feeding the poor, giving money to friends in need, it was all a way of redeeming himself. And that, I believe, is what true redemption is, Amir jan, when guilt leads to good.
That was a long time ago, but it"s wrong what they say about the past, I"ve learned, about how you can bury it. Because the past claws its way out. (1)
But coming close wasn"t the same as winning, was it? ... He had won because winners won and everyone else just went home. (56)
It was Homaira and me against the world... In the end, the world always wins. That"s just the way of things. (99) Rahim Khan

声速的测量实验报告2
实验目的：
1)探究影响声速的因素，超声波产生和接收的原理。
2)学习、掌握空气中声速的测量方法 3)了解、实践液体、固体中的声速测量方法。 4)三种声速测量方法作初步的比较研究。
实验仪器:
1)超声波发射器 2)超声波探测器 3)平移与位置显示部件。 4)信号发生器： 5)示波器
实验原理： 1)空气中：
a.在理想气体中声波的传播速度为
v88
(式中8088cp
cV
(1)
称为质量热容比，也称“比热[容]比”，它是气体的质
量定压热容cp与质量定容热容cV的比值;M 是气体的摩尔质量，T是绝对温度，R=8.314472(1±1.7×10-6)Jmol-1K-1为摩尔气体常量。)
标准干燥空气的平均摩尔质量为Mst =28.966�8�710-3kg/mol b.在标准状态下(T0�8�8273.15
K,p�8�8101.3�8�8kPa)，干燥空气中的声速
为v0=331.5m/s。在室温t℃下，干燥空气中的声速为
v88v0
(2)
(T0=273.15K)
c.然而实际空气总会有一些水蒸气。当空气中的相对湿度为r时，若气温为t℃时饱和蒸气压为pS，则水汽分压为rps。经过对空气平均摩尔质量 M 和质量热容比8�0 的修正，在温度为t、相对湿度为r的空气中，声速为
(在北京大气压可近似取p�8�4 101kPa;相对湿度r可从干湿温度计上读出。温度t℃时的饱和水汽压ps可用lgps�8�810.286�8�21780237.3�8�0trp�8�3v8833�8�01s�8�416�8�5 m s (3)计算)
d.式(3)的计算结果与实际的超声声速真值可能有一定偏差。
引起偏差的原因有： ~状态参量的测量误差 ~理想气体理论公式的近似性~实际超声声速还与频率有关的声“色散”现象等。
实验方法：
A. 脉冲法：利用声波传播时间与传播距离计算声速
实验中用脉冲法测量，具体测量从脉冲声源(声发射器)到声探测器
之间的传播时间tSD和距离lSD，进而算出声速v (实验中声源与探测器之间基本是同一被测煤质)
lSD
v88t
SD
B. 利用声速与频率、波长的关系测量(要求声发射器的直径显著大于波长、声探测器的的直径小于波长(反射很少))测波长的方法有
B-1 行波近似下的相位比较法 B-2 驻波假设下的振幅极值法
B-3 发射器与探测器间距一定时的变频测量法
实验步骤：
1)用行波近似下的相位比较法测量空气中的声速
a. 正确接线 将信号发生器的输出连接到声速仪的超声发射器信号的输入端的T型三通接头上，三通的另一个借口用导线连到示波器的一个输入端。声速仪的探测信号输出端连接到示波器的另一输入端上 b. 选定频率 当探测器距离发射器约100mm时，调节信号发生器的频率，调节范围为30~50kHz，同时记录接收信号的最大峰峰值。 得到如下数据：
作出图像：
要求选定某一使探测器输出信号幅度较大的频率作为实验测量时的声波频率，所以频率应选为40.5KHz。
c. 测同相点位置 单向缓慢移动探测器，同时观察发射器、探测器波形，当波峰在同一竖直线上时，记录此时数显卡尺读数值。然后继续移动探测器，记录七个相邻的波峰相同的位置。
2)用驻波假设下的振幅极值法测量空气中的声速单向平移声发射器，依次找出7个相邻极大值位置，并记录。
3)用行波近似下的相位比较法测量水中的声速
实验步骤与在空气中的实验步骤基本相同(除了实验开始时把实验装置换为的水中的实验装置)频率为：90.0KHz
实验结果：
1)用行波近似下的相位比较法测量空气中的声速
数据记录如下：
实验前的气温23.6℃ 相对湿度28.7 实验后的气温25.0℃ 相对湿度30.2
由此计算出的空气中的理论值为：v=346.43m/s
用最小二乘法直线拟合的方法求波长得：λ=(8.65±0.04)mm 声速：(346.17±1.61)m/s 理论偏差：0.00075
2)用驻波假设下的振幅极值法测量空气中的声速
数据记录如下：
用最小二乘法直线拟合的方法求波长得：λ=(8.70±0.04)mm 声速：(347.86±1.61)m/s 理论偏差：0.0039
4)用行波近似下的相位比较法测量水中的声速
数据记录：
用最小二乘法直线拟合的方法求波长得：(λ=17.33±0.14)mm 声速：(1359.43±12.62)m/s
总结与反思：这次实验使我认识到自己对实验仪器了解的不足。
