阅读下列短文，从每题所给的A、B、C、D四个选项中，选出最佳选项。
A
There were two things in the world that Ghagra Geeta Bali hated. The first was the way, Rani, the domestic help, combed her hair. The second was, you guessed it, her name. She hated her name so much that she prayed to god every night: Dear god, let me be born again. So I can have a name like Rita or Preeti. A short, smart one-word name.
On Tuesday, Ghagra Geeta Bali and her mother went for their usual shopping. There was a long queue of children just outside the record store. They went closer to look. It was yet another scheme to sell a few audio cassettes. Everyone who bought a cassette qualified for the scheme.
In this case, the artist whose songs were featured on the cassette was a young sensation called Malik Faridabadi, a great favorite with teenagers. Ghagra Geeta Bali was no exception.
A friendly young man was writing down the names of the people who wanted to participate in the scheme. Out of this long list Malik would pick one name, and the chosen one would get to meet him, plus of course, win many freebies (赠品).
But when her mother asked her to participate, Ghagra Geeta Bali said no. She didn’t want to, speak out her name in front of so many people and make herself the butt (笑料) of amusement. But mothers being mothers, she just went up to the man and told him in firm tones: “Please enter my daughter’s name. It is Ghagra Geeta Bali.”
“It is what?” the man asked, naturally a little taken aback.
“G-h-a-g-r-a G-e-e-t-a B-a-l-i. There she is,” she replied while pointing to her daughter. The crowd standing around also turned to stare. All Ghagra Geeta Bali wanted then was for the earth to open up and swallow her.
That did not happen. But the following week she received a call. It was from the recording company that had announced the scheme. And they told her that she was the chosen one.
“It is all because of your name,” said the public relations man who had called. “Mr Faridabadi took one look at it in the list and said that he couldn’t wait to meet the brave girl bearing it.”

l 1-year-old Courtney Thompson was so passionate about gymnastics that she would practice five hours a day until her arms were sore and her elbows swollen. She rarely complained about her tough schedule, and for good reason. Courtney was ranked the best gymnast in the state for her age, and she dreamed of going to the Olympics. But on January 12th, 2005, while practicing a routine exercise, she felt an unbearable pain in the left elbow. The medical examination then revealed a severe injury, resulting in an immediate surgery, and a slow, painful recovery.
What happened to Courtney Thompson
is a red flag in
There are many reasons behind the outbreak in sports injuries, but most experts agree on one: the extreme culture of organized youth sports. Gone are the days when children played a variety of games on playgrounds. Child kidnapping and street crime have ended casual neighborhood athletics in many places, leading parents to enroll their children in organized sports under the watchful, though demanding, eyes of adult volunteers and coaches. And movies like Friday Night Lights glorify the thrill of victory for young athletes with single-minded dedication to athletic achievement.
From high school gyms to county ball fields, 41 million children younger than 19 participated in organized youth sports in 2005, according to the latest research by the National Council of Youth Sports. The figure represents a 25 percent increase since 1997.

Parental involvement in youth sports has also made childhood games less about having fun and more about training and competing for the top spot, landing a college scholarship or launching a promising career.

Many children first learn the value of money by receiving an allowance (pocket money). The purpose is to let children learn from experiences at an age when financial mistakes are not very costly.
The amount of money that parents give to their children to spend as they wish differs from family to family. Timing is another consideration. Some children get a weekly allowance. Others get a monthly allowance.
In any case, parents should make clear what, if anything, the child is expected to pay for with the money. At first, young children may spend all of their allowance soon after they receive it. If they do this, they will learn the hard way that spending must be done within a budget. Parents are usually advised not to offer more money until the next allowance.
The object is to show young people that a budget demands a choice between spending and saving. Older children may be responsible enough to save money for larger costs, like clothing or electronics. Many people who have written on the subject of allowances say it is not a good idea to pay your child for work around the home. These jobs are a normal part of family life.
Paying children to do extra work around the house, however, can be useful. It can even provide an understanding of how a business works.
Allowances give children a chance to experience the three things they can do with money. They can share it in the form of gifts or giving to a good cause. They can spend it by buying things they want. Or they can save it.
Saving helps children understand that costly goals require sacrifice. You have to cut costs and plan for the future. Requiring children to save part of their allowances can also open the door to future saving and investing. Many banks offer services to help children and teenagers learn about personal finance.
A savings account is an excellent way to learn about the power of compound interest.
Compounding works by paying interest on interest. So, for example, one dollar invested at two percent interest for two years will earn two cents in the first year. The second year, the money will earn two percent of one dollar and two cents, and so on. That may not seem like a lot. But over time it adds up.
71. Giving an allowance, parents should consider all the following EXCEPT_______.
A. how much the child should get each time
B. whether the child has made a budget
C. where the money really goes
D. how often a child can get it
72. According to the passage, how can a child learn to have a budget?
A. Through their own experiences.
B. Through parents’ instruction.
C. By spending allowance.
D. By receiving allowance.
73. The author of the passage holds the opinion that_______.
A. what children learn by handling allowances may be beneficial in the future
B. children can learn to set up their own business with their allowances
C. keeping allowances in the bank is the best choice for children
D. it is not a good idea to pay children to do housework at home
74. The underlined words “compound interest” in the passage probably means_______.
A. increasing curiosity to learn how to make more money
B. stronger power to hold one’s attention to saving money
C. money paid by the bank on your original money and the gain from it
D. the sum of money that you earn from keeping your money in the bank
75. What is the best title for the passage?
A. Be Generous To Pay Your Children
B. Be Wise To Avoid Financial Mistakes
C. Saving Allowances Does Good To Children
D. Allowances Help Children Learn About Money

24．（20分）如图15（甲）所示为一种研究高能粒子相互作用的装置，两个直线加速器均由k个长度逐个增长的金属圆筒组成（整个装置处于真空中。图中只画出了6个圆筒，作为示意），它们沿中心轴线排列成一串，各个圆筒相间地连接到正弦交流电源的两端。设金属圆筒内部没有电场，且每个圆筒间的缝隙宽度很小，带电粒子穿过缝隙的时间可忽略不计。为达到最佳加速效果，需要调节至粒子穿过每个圆筒的时间恰为交流电的半个周期，粒子每次通过圆筒缝隙时，都恰为交流电压的峰值。
质量为m、电荷量为e的正、负电子分别经过直线加速器加速后，从左、右两侧被导入装置送入位于水平面内的圆环形真空管道，且被导入的速度方向与圆环形管道中粗虚线相切。在管道内控制电子转弯的是一系列圆形电磁铁，即图15（甲）中的A1、A2、A3……An，共n个，均匀分布在整个圆周上（图中只示意性地用细实线画了几个，其余的用细虚线表示），每个电磁铁内的磁场都是磁感应强度均相同的匀强磁场，磁场区域都是直径为d的圆形。改变电磁铁内电流的大小，就可改变磁场的磁感应强度．从而改变电子偏转的角度。经过精确的调整，可使电子在环形管道中沿图中粗虚线所示的轨迹运动，这时电子经过每个电磁铁时射入点和射出点都在电磁铁内圆形匀强磁场区域的同一条直径的两端，如图15（乙）所示。这就为实现正、负电子的对撞做好了准备。

（3）为确定这部分菌株在基本培养基不能生长的原因，科学家们继续做实验：在基本培养基中补充了某种物质，原来不能生长的菌株有的能够生长了。从而获得了三种与野生型菌株不同的突变型菌株A、B、C。实验结果见下表：
实验分析：在哺乳动物的肝脏中，精氨酸是经过“前体→鸟氨酸→瓜氨酸→精氨酸”的途径合成的。受这种生化观点的启发，科学家们认为：野生型脉孢霉可以利用基本培养基中的某类物质（前体），合成了一系列氨基酸，这些氨基酸应该属于脉胞霉的_________________代谢产物。
三种突变型菌株均能在添加了精氨酸的培养基中生长，说明它们均丧失了_________________的功能。突变菌株B可在添加了瓜氨酸的培养基中生长，但不能在添加鸟氨酸的培养基中生长，原因是它_________________。
（4）生化反应都由特定的酶来催化，一个基因突变导致了一个生化反应的不能进行，科学家们由此提出了“一个基因控制合成一个酶”的假说。在进一步的猜测中，有一种观点认为基因突变使细胞合成了一种结构发生改变而失去活性的“酶”。于是有人继续探讨这个问题。一种免疫反应可检测到失活“酶”的存在，科学家们利用这种方法做了下面的实验。
