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 (贈(zèng)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.”
56. Ghagra Geeta Bali didn’t like her name because_______.
A. it would bring her a lot of trouble
B. it was too long and not beautiful
C. it would make her angry

58. What is the message of the story?

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.

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

29．（12分）生長(zhǎng)素的主要作用是促進(jìn)細(xì)胞縱向伸長(zhǎng)，其作用機(jī)理如圖20所示，請(qǐng)回答下列問(wèn)題：
（1）生長(zhǎng)素作用的第一步是與細(xì)胞膜上的受體結(jié)合，形成“激素―受體復(fù)合物”，這一過(guò)程體現(xiàn)了細(xì)胞膜的_________________功能。
（2）被激活的“激素―受體復(fù)合物”能引起內(nèi)質(zhì)網(wǎng)釋放Ca2+，Ca2+促使細(xì)胞內(nèi)的H+以_________________的方式運(yùn)往細(xì)胞外，增加了細(xì)胞壁的延展性，使細(xì)胞壁對(duì)細(xì)胞的壓力減小，導(dǎo)致細(xì)胞吸水、體積增大而發(fā)生不可逆增長(zhǎng)。細(xì)胞在生長(zhǎng)過(guò)程中體積變化最大的細(xì)胞器是_____________。實(shí)驗(yàn)發(fā)現(xiàn)，細(xì)胞在持續(xù)生長(zhǎng)過(guò)程中，細(xì)胞壁的厚度能基本保持不變，出現(xiàn)這種現(xiàn)象的原因是由于__________（填細(xì)胞器）為細(xì)胞壁添加了新的成分。
（3）此外，Ca2+還能激活細(xì)胞中的轉(zhuǎn)錄因子，它進(jìn)入細(xì)胞核后，能引起_______________酶催化mRNA的合成。
（4）生長(zhǎng)素促進(jìn)根系生長(zhǎng)的最適宜濃度要比莖低得多，稍高濃度的生長(zhǎng)素能促進(jìn)乙烯的生物合成，從而抑制了根的伸長(zhǎng)，這說(shuō)明生長(zhǎng)素的作用具有_________________。
30．（18分）科學(xué)家用脈孢霉（一種真菌）為實(shí)驗(yàn)材料，對(duì)基因的功能進(jìn)行了深入的研究。
（1）野生型脈孢霉在基本培養(yǎng)基上即可生長(zhǎng)，基本培養(yǎng)基只含有野生型脈孢霉生長(zhǎng)所必需的最低限度的營(yíng)養(yǎng)成分�；九囵B(yǎng)基中所含的營(yíng)養(yǎng)要素可以歸納為：____________________________________________________
_________________________________________。
（2）科學(xué)家用X射線處理野生型脈孢霉后，發(fā)現(xiàn)部分菌株在基本培養(yǎng)基上不能生長(zhǎng)。用X射線處理脈孢霉的目的是_______________________________。
（3）為確定這部分菌株在基本培養(yǎng)基不能生長(zhǎng)的原因，科學(xué)家們繼續(xù)做實(shí)驗(yàn)：在基本培養(yǎng)基中補(bǔ)充了某種物質(zhì)，原來(lái)不能生長(zhǎng)的菌株有的能夠生長(zhǎng)了。從而獲得了三種與野生型菌株不同的突變型菌株A、B、C。實(shí)驗(yàn)結(jié)果見(jiàn)下表：
實(shí)驗(yàn)分析：在哺乳動(dòng)物的肝臟中，精氨酸是經(jīng)過(guò)“前體→鳥(niǎo)氨酸→瓜氨酸→精氨酸”的途徑合成的。受這種生化觀點(diǎn)的啟發(fā)，科學(xué)家們認(rèn)為：野生型脈孢霉可以利用基本培養(yǎng)基中的某類(lèi)物質(zhì)（前體），合成了一系列氨基酸，這些氨基酸應(yīng)該屬于脈胞霉的_________________代謝產(chǎn)物。
三種突變型菌株均能在添加了精氨酸的培養(yǎng)基中生長(zhǎng)，說(shuō)明它們均喪失了_________________的功能。突變菌株B可在添加了瓜氨酸的培養(yǎng)基中生長(zhǎng)，但不能在添加鳥(niǎo)氨酸的培養(yǎng)基中生長(zhǎng)，原因是它_________________。
（4）生化反應(yīng)都由特定的酶來(lái)催化，一個(gè)基因突變導(dǎo)致了一個(gè)生化反應(yīng)的不能進(jìn)行，科學(xué)家們由此提出了“一個(gè)基因控制合成一個(gè)酶”的假說(shuō)。在進(jìn)一步的猜測(cè)中，有一種觀點(diǎn)認(rèn)為基因突變使細(xì)胞合成了一種結(jié)構(gòu)發(fā)生改變而失去活性的“酶”。于是有人繼續(xù)探討這個(gè)問(wèn)題。一種免疫反應(yīng)可檢測(cè)到失活“酶”的存在，科學(xué)家們利用這種方法做了下面的實(shí)驗(yàn)。
第一步 設(shè)法得到影響上述生化反應(yīng)的酶，將其純化制成酶制劑，注射到家兔體內(nèi)，獲得相應(yīng)的抗酶抗體（能和正常的酶及失活的“酶”發(fā)生沉淀反應(yīng)）。酶制劑在免疫學(xué)上屬于_________________。
第二步 在培養(yǎng)皿的瓊脂上挖四個(gè)圓孔（如圖21所示），在0號(hào)圓孔中加入抗酶抗體，在2號(hào)圓孔中加入野生型菌株提取物，3號(hào)圓孔中加入某突變菌株提取物，則l號(hào)圓孔中需加入_________________作為對(duì)照。
第三步 0、l、2、3號(hào)圓孔中的物質(zhì)各自在瓊脂中擴(kuò)散，觀察l、2、3號(hào)圓孔與0號(hào)圓孔之間是否出現(xiàn)_________________。
實(shí)驗(yàn)結(jié)果分析：若出現(xiàn)________________________________________________
結(jié)果時(shí)，則支持“基因突變使細(xì)胞合成了一種失去活性的‘酶’”的推斷。

（填字母）的柱寬過(guò)大時(shí)，會(huì)導(dǎo)致草場(chǎng)退化、沙化等現(xiàn)象的出現(xiàn)。因此，合理確定草場(chǎng)的_________________，才能保證畜牧業(yè)生產(chǎn)的可持續(xù)發(fā)展。
（4）若該圖表示農(nóng)田生態(tài)系統(tǒng)，怎樣利用農(nóng)作物秸桿中的能量是一個(gè)值得研究的問(wèn)題。如果將秸稈做廢棄物燃燒就不能充分利用秸稈中的能量，而將秸稈做飼料喂牲畜，再利用牲畜的糞便進(jìn)行沼氣發(fā)酵，就會(huì)使秸稈中的能量更多地流向_________________的部分。同時(shí)，其中的物質(zhì)也能被充分利用。
（5）若該圖表示城市生態(tài)系統(tǒng)，如果居民的生產(chǎn)、生活產(chǎn)生了過(guò)多的廢棄物，圖中_________________（填字母）的柱寬就會(huì)明顯加大，相應(yīng)地就出現(xiàn)了環(huán)境污染。例如白色污染（聚乙烯）已經(jīng)成為一個(gè)嚴(yán)重的社會(huì)問(wèn)題，從生態(tài)系統(tǒng)物質(zhì)循環(huán)的角度來(lái)看，造成白色污染的根本原因是___________________________________。
（6）若該圖表示湖泊生態(tài)系統(tǒng)，如果要調(diào)查生態(tài)系統(tǒng)的能量流動(dòng)情況，可采用黑白瓶法。該方法是從湖泊的一定深度取水樣，測(cè)其初始的溶氧量。然后將水樣分裝在透光的白瓶和不透光的黑瓶中，黑白瓶都放回取樣深度，一段時(shí)間后取出，再測(cè)其溶氧量。此時(shí)，黑瓶中溶氧量的變化是瓶中生物_________________的氧氣量，而白瓶中溶氧量的變化是瓶中生物___________________________________________________________之差，這些數(shù)值可用來(lái)研究該水層是否存在光能自養(yǎng)生物，以及它們固定太陽(yáng)能的多少等問(wèn)題。
