Are you a social butterfly, or do you prefer being at the edge of a group of friends? Either way, your genes and evolution may play a major1, US researchers reported on Monday.
While it may come as no surprise that genes may help explain 2some people have many friends and others have 3 , the researchers said, their findings go just a little farther than that.
"Some of the things we find are4uncommon," said Nicholas Christakis of Harvard University in Massachusetts, who helped5the study.
"We find that how interconnected your friends are6on your genes. Some people have four friends who know each other and some people have four friends who don't7each other. 8Dick and Harry know each other depends on Tom's 9 ," Christakis said in a telephone interview.
Christakis and colleague James Fowler of the University of California San Diego are 10known for their studies that show obesity, smoking and happiness spread in networks.
For this study, they and Christopher Dawes of UCSD used national data that11more than 1,000 identical(同卵的) and fraternal(異卵的) twins’ genes. Because 12share an environment, these studies are good for showing the impact that genes have13various things, because identical twins14all their genes while fraternal twins share just half.
"We found there appears to be a genetic tendency to introduce your friends15each other," Christakis said.
There could be good, evolutionary reasons16this. People in the middle of a social network could be secret to useful gossip,17the location of food or good investment choices.
But they would also be at risk of catching effects from all sides -- in which case the advantage would18more cautious social behavior, they wrote in the Proceedings of the National Academy of Sciences.
"It may be that natural selection is19not just things like whether or not we can resist the common cold, but also who it is that we are going to come into 20with," Fowler said in a statement.

本文說(shuō)明的是一個(gè)人的朋友的多寡取決于他的基因。做本完形填空的時(shí)候,我們要把生活中的實(shí)際情況和文章中作者的思路相結(jié)合。
1. A你的基因及進(jìn)化過(guò)程可能在這一問(wèn)題上起著重要的作用(也就是A項(xiàng))。BCD三項(xiàng)依次分別表示的意思是:規(guī)則,卷,棒桿,語(yǔ)意上都不適合。
2. B研究人員稱(chēng),用基因解釋為什么(也即是:why)有些人朋友眾多而有些人卻寡朋少友其實(shí)并不新鮮。ACD項(xiàng)依次表示:在哪兒,在什么時(shí)候,哪一個(gè),語(yǔ)意和邏輯上與語(yǔ)境不符。
3. C根據(jù)上一題的分析,此空應(yīng)表示“沒(méi)有”之意,即是:few,ABD三項(xiàng)都表的確“有”。
4. D研究人員這兒是說(shuō)他們發(fā)現(xiàn)的一些現(xiàn)象的確很奇怪!暗拇_”就是“確實(shí)”,就是“說(shuō)實(shí)話(huà)”,也即是“坦誠(chéng)地”(frankly),ABC三項(xiàng)依次分別表示:大體上地,主要地,大部分地,這些都不和語(yǔ)意相契合。
5. A來(lái)自馬薩諸塞州哈佛大學(xué)的Nicholas Christakis協(xié)助開(kāi)展該研究。這里的“開(kāi)展”研究,就是“做”研究,A項(xiàng)的conduct:做,實(shí)施,非常合適,而B(niǎo)CD三項(xiàng)的意思依次是:介紹,沖突,生產(chǎn)。
6. A我們發(fā)現(xiàn)一個(gè)人朋友之間的親密程度取決于這個(gè)人的基因,“取決于”: depends。 BCD各項(xiàng)加上on之后的意思是:基礎(chǔ)是,呈現(xiàn),穿上,都不能和語(yǔ)境契合。
7. D結(jié)合語(yǔ)境:有的人有四個(gè)朋友而且互相認(rèn)識(shí);而有的人有四個(gè)朋友,但他們卻素不相識(shí)(即是know)。ABC三項(xiàng)分別表示:看到,檢查,學(xué)會(huì)。
8. D迪克和哈利是否(就是whether)互相認(rèn)識(shí)是取決于湯姆的基因。ABC三項(xiàng)中的“何時(shí),何地,什么”都與邏輯不搭配。
9. A由上面的分析我們得知全文都是講的“基因”,故這兒就填A(yù)項(xiàng)genes(gene的復(fù)數(shù)形式),而不是BCD三項(xiàng)分別依次表示的意思:大腦,外貌,形象。
10.B Christakis和他的同事、來(lái)自加利福尼亞大學(xué)圣地亞哥分校的James Fowler此前以研究肥胖、吸煙以及快樂(lè)會(huì)在朋友之間傳播而十分著名,可以確定CD兩項(xiàng)錯(cuò),因?yàn)樗鼈儽硎欠穸êx:較不,最不;而這里有沒(méi)有和那些人“比起來(lái)”之意,所以A項(xiàng)的better也錯(cuò)了。這里只是用形容詞的最高級(jí)形式表示“很,非常,極其”來(lái)修飾known(出名)。故B項(xiàng)正確。
11.D Christopher Dawes of UCSD使用了一項(xiàng)全國(guó)性數(shù)據(jù),這項(xiàng)數(shù)據(jù)對(duì)1000多對(duì)同卵及異卵雙胞胎的基因進(jìn)行了對(duì)比。因?yàn)槭菙?shù)據(jù)(data)所以最令人迷惑的是A項(xiàng)recorded(記錄),但是是兩類(lèi)基因,所以比較合理的邏輯應(yīng)該是compared(比較)。BC兩項(xiàng)所表示的意思分別依次是:舉例證明,形容描繪,與上面的語(yǔ)境不契合。
12.C由于雙胞胎生活在同一個(gè)環(huán)境,而且同卵雙胞胎的基因完全相同,而異卵雙胞胎有一半的基因相同,所以這些研究有助于發(fā)現(xiàn)基因?qū)θ烁鱾(gè)方面的影響。再加上上文就說(shuō)是“雙胞胎”(twins)。ABD項(xiàng)的意思以此事:兄弟,姐妹,堂兄妹,都不合乎語(yǔ)境。
13.B 由上一題的解析我們知道:that genes have 13 various things,是定語(yǔ)從句修飾impact(影響),而have an impact on是個(gè)固定詞組,意思是:對(duì)……有影響。ACD依次表示:和,為了,對(duì)于,它們都與impact不搭配。
14.A由第12題的分析我們得知此空填上表示“有完全相同”的基因,這四個(gè)詞中表示這個(gè)意思的只有share(分享,共同擁有)和這個(gè)語(yǔ)境相吻合,其余BCD三項(xiàng)表示的:有,擁有,說(shuō)明之意都不合乎邏輯。
15.B我們發(fā)現(xiàn)人們?cè)诮榻B朋友互相認(rèn)識(shí)時(shí)有一個(gè)基因傾向性。“介紹朋友互相認(rèn)識(shí)”用英語(yǔ)表示就是introduce……to……,也就是B項(xiàng)。Introduce與into, in, from都不是合理的搭配。
16.A這種傾向性可以用合理的、進(jìn)化方面的原因來(lái)解釋。這兒是表示“…的原因”,也就是英語(yǔ)中用“reason for”來(lái)表示,而不是with, to, at。
17.D處于社交圈中的人們可能會(huì)對(duì)一些有用信息的保密,比如哪些地方有吃的,或者好的投資選擇等等,這里是舉例,也即是D項(xiàng)such as……例如,A項(xiàng)表示:還有,B項(xiàng)是:因?yàn),C項(xiàng):對(duì)于,與語(yǔ)境都不能合理的吻合。
18.C好處只有存在于社交活動(dòng)謹(jǐn)慎的人中,表示“存在于”之意的動(dòng)詞短語(yǔ),即是:C項(xiàng):lie in,ABD三項(xiàng)分別表示:堅(jiān)持,引進(jìn),派人去請(qǐng)。無(wú)論意義還是邏輯上都不合適。
19.A可能自然選擇對(duì)我們接觸什么樣的人也有影響!蔽覀兊弥丝找钌媳硎尽坝杏绊憽敝獾膭(dòng)詞短語(yǔ),就是act on,acting只不過(guò)是現(xiàn)在分詞形式。BCD三項(xiàng)各自表示:穿上,依賴(lài),(向前)傳遞或轉(zhuǎn)發(fā),和上面的語(yǔ)境不相契合。
20.D由上一題的語(yǔ)境我們知道,此空需要填上表示“接觸聯(lián)系”之意的名詞,也即是D項(xiàng):contact,其余BCD三項(xiàng)雖然都和with搭配,但都不是“接觸聯(lián)系”之意,它們分別依次表示:訂合同,面對(duì),連接。

I was shopping in the supermarket when I heard a young voice.
“Mom, come here! There’s this lady here my size!”
The mother rushed to her son; then she turned to me to apologize.
I smiled and told her, “It’s okay.” Then I talked to the boy, “Hi, Mickey, I’m Darry Kramer. How are you?”
He studied me from head to toe, and asked, “Are you a little mommy?”
“Yes, I have a son,” I answered.
“Why are you so little?” he asked.
“It’s the way I was born,” I said. “Some people are little. Some are tall. I’m just not going to grow any bigger.” After I answered his other questions, I shook the boy’s hand and left.
My life as a little person is filled with stories like that. I enjoy talking to children and explaining why I look different from their parents.
It takes only one glance to see my uniqueness. I stand three feet nine inches tall. I was born an dwarf (侏儒). Despite this, I did all the things other kids did when I was growing up.
I didn’t realize how short I was until I started school. Some kids laughed at me.. I began to hate the first day of school each year. New students would always stare at me as I struggled to climb the school bus stairs.
But I learned to smile and accept the fact that I was going to be noticed my whole life. I decided to make my uniqueness an advantage rather than a disadvantage. What I lacked in height, I made up for in personality.
I’m 47 now, and the stares have not diminished as I’ve grown older. People are amazed when they see me driving. I try to keep a good attitude. When people are rude, I remind myself, “Look what else I have---a great family, nice friends.”
It’s the children’s questions that make my life special. I enjoy answering their questions. My hope is that I will encourage them to accept their peers (a person of the same age, class, position, etc.), whatever size and shape they come in, and treat them with respect.
【小題1】Why did the mother apologize to the author?

D
Ben walked quietly. He wanted to surprise the hunter. But then, what would he do?
Suddenly he heard a bird’s wings beating the dry grass. Ben moved quickly toward the sound.
He saw a colored head ... the head of a beautiful bird. The bird did not move until Ben came close. Then it tried to fly away, but one wing was broken.
Ben lifted the bird and held it close against his body. The bird fought to escape, but soon lay quietly in Ben’s arms.
Ben decided to take the bird home and fix its broken wings so that it could fly again.
He was almost out of the woods when he heard the hunter behind him.
“You just found that bird?” the hunter asked.
“Yes,” Ben answered.
“It is mine!”
Ben was afraid and tried to answer, but his mouth was too dry to speak. Nevertheless, he wetted his lips and said, “No.”
“I shot him and I say he is mine!”
“But he is not dead yet,” Ben answered, “and besides, anything on my land belongs to me.”
The hunter looked down at the little man and smiled. “Say, who are you?”
Ben’s voice shook with both fear and anger. “I own this land. There are signs everywhere that say, ‘No hunting’.”
“No need to get angry, mister,” the hunter said. “Control yourself.”
There was something threatening in the man’s cool quiet voice. And he had a gun. His arms were free and Ben’s were not.
The hunter stepped closer and said, “Give me that bird!”
Ben was white with anger. “No!” he answered. His eye glasses became wet and he had to look over the top of them to see the other man.
“Give me the bird and I will go away,” the hunter said.
“You get off my land,” Ben told him. “Get off right now...you do not belong here!”
The man’s face got red. “Mister,” he said, “I have been hunting here all my life. I grew up here.”
“That is a thing of the past,” Ben said. “I do not know who you are and I do not care. I own this place now and I am telling you to leave. You go back through the woods and get off my land!”
“Now look, mister,” the hunter said, “be reasonable.”
The hunter raised his gun.
A cold wind blew across Ben’s face. He looked into the hunter’s gray eyes. Ben was frightened. It was not too late, he thought. He could still give the bird to the hunter and return safely home...that would end this whole ugly business.
The bird struggled weakly and made a wild, strange noise.
Then Ben knew he could never give this bird to the hunter. This feeling gave Ben great strength, and he was no longer afraid.
“I will never let you kill this bird,” he said. “Get away from here. If you try to take this bird, I will fight...you have a gun and you are bigger, but that does not worry me. You will never get this bird...you will have to kill me first.”
The two men looked at each other. Ben’s fear returned. His knees began to shake and he felt sick. Yet he stood straight, wondering what would happen next.
They stood close to each other for a long time. The woods were strangely quiet. Then the hunter’s rough voice broke the silence.
“You are a fool.” And then to Ben’s surprise, he slowly walked away.
Ben watched until he was gone. His arms hurt, his body felt wet and cold.
67. Why did the hunter smile when saying “Say, who are you”?
A. He wanted to confirm Ben’s identity in a friendly way.
B. He was amused at Ben’s reply and interested in him.
C. He looked down on Ben and thought his reply ridiculous.
D. He meant to be friendly enough to get the bird from Ben.
68. What strengthened Ben’s determination never to give the bird to the hunter?
A. His strong dislike of the hunter.     B. His firm confidence in himself.
C. His ownership of this piece of land.   D. His concern and sympathy for the bird.
69. Why did the hunter remark that Ben was a fool at the end of the story?
A. Ben tried to protect a bird at all costs.
B. Ben pretended to be fearless although scared.
C. Ben stood close to him saying nothing for long.
D. Ben insisted on him leaving the land.
70. Which of the following best describes Ben’s state of mind in the incident?
A. Ben was willing to compromise.                    B. Ben never thought of giving in.
C. Ben held out to the end.                                D. Ben was sure about his victory.

Are you a compulsive spender, or do you hold on to your money as long as possible? Are you a bargain hunter? Would you rather use charge accounts than pay cash? Your answers to these questions will reflect your personality. According to psychologists, our individual money habits not only show our beliefs and values, but can also stem from past problems.

Experts in psychology believe that for many people, money is an important symbol of strength and influence. Husbands who complain about their wives’ spending habits may be afraid that they are losing power in their marriage. Wives, on the other hand, may waste huge amounts of money because they are angry at their husbands. In addition, many people consider money a symbol of love. They spend it on their family and friends to express love, or they buy themselves expensive presents because they need love.

People can be addicted to different things — for example, alcohol, drugs, certain foods, or even television. They are compulsive in their addictions, i.e. they must satisfy these needs to feel comfortable. In the same way, according to psychologists, compulsive spenders must spend money. For people who buy on credit, furthermore, charge accounts are even more exciting than money: in other words, they feel that with credit, they can do anything. Their pleasures in spending enormous amounts are actually greater than those they get from the things they buy.

There is even a special psychology of bargain hunting. To save money, of course, most people look for sales, low prices, and discounts. Compulsive bargain hunters, however, often buy things that they don’t need just because they are cheap. They want to believe that they are helping their budgets, but they are really playing an exciting game: when they can buy something for less than other people, they feel that they are winning. Most people, experts claim, have two reasons for their behavior: a good reason for the things that they do and the real reason.

It is not only scientists, of course, who understand the psychology of spending habits, but also business people. Stores, companies, and advertisers use psychology to increase business: they consider people’s needs for love, power, or influence, their basic values, their beliefs and opinions, etc. in their advertising and sales methods.

Psychologists often use a method called “behavior therapy(療法)” to help individuals solve their personality problems. In the same way, they can help people who feel that they have problems with money: they give them “assignments”. If a person buys something in every store that he enters, for instance, a therapist might teach him self-discipline in this way: on the first day of his therapy, he must go into a store, stay five minutes, and then leave. On the second day, he should stay for ten minutes and try something on. On the third day, he stays for fifteen minutes, asks the salesclerk a question, but does not buy anything. Soon he will learn that nothing bad will happen to him if he doesn’t buy anything, and he can solve the problem of his compulsive buying.  

1.If you use charge accounts, ____.

A.you pay in cash                         B.you pay with credit card

C.you pay less than you should               D.you pay more than you should

2.Compulsive bargain hunters buy things for all the following reasons except that ____.

4.The underlined word “those” in Paragraph 3 refers to ____.

A.different things                         B.their addictions

C.charge accounts                        D.their pleasures

5.From the passage we can conclude that ____.
