Genes are found in every plant or animal cell. They are the basic units of life that are capable of passing specific 72_______from one generation to another. For example, whether you are tall or short depends upon the genes that you 73______from your parents. Cloning plants or animals is a process that 74_______ the production of a new organism that is genetically identical to the organism from which cells were taken. Although this 75_____ has aroused great interest around the world over the last ten years or so, cloning is not something new in nature. Most mothers give birth to just one child at a time; however, on rare 76_______a mother may give birth to a set of twins. If these two children are identical twins, then they are in fact naturally 77________clones of each other, although not of the parents. The reason for them being clones is that the two children originated from one 78______egg and consequently they are genetically identical. Twins that develop from two79________eggs are not clones of each other.
Cloning also occurs naturally in plants. Strawberry plants reproduce themselves by sending out runners, or modified stems, and these runners take root a short distance from the 80_____ plant and start to grow, and to produce fruit. In time, this plant sends out runners of its own that also take root. This is known as asexual reproduction; in other words, reproduction that does not involve the fusion (融合) of male and female cells. The newly 81____ plants are clones of the original. In addition to strawberry plants, certain types of flowers and grasses reproduce themselves in the same way. Throughout history, people have also facilitated cloning by taking small cuttings from plants and then growing them into new plants. This form of cloning is called vegetative propagation.

Directions: For each blank in the following passage there are four words or phrases marked A, B, C and D. Fill in each blank with the word or phrase that best fits the context.(15’)
Robert Frank, an economist at Cornell, believes that his profession is restricting cooperation and generosity. In the U.S., economics professors give __51__ money to charity than professors in other fields. Economics students in Germany are more likely than those from other majors to recommend an overpriced plumber (水管工) when they are __52__ to do it. Economics majors tend to rate __53_ as “generally good,” “correct,” and “moral” more than their peers. Does studying economics change people? Maybe not. It could be self-selection: students who already believe in self-interest are __54__ to economics. But this doesn't exclude the possibility that studying economics pushes people further toward the selfish extreme. By spending time with like-minded people, economics students may become __55__ that selfishness is widespread and reasonable -- or at least that giving is rare and foolish.“As a business school professor, these effects worry me, as economics, __56__ every aspect of our lives, is taught widely in business
schools, providing a __57__ for courses in management, finance, and accounting.” says Frank.If economics can __58_ pro-social behavior, which is central to the well-being of people or society, what should we do about it? A change in economics and business __59__ is suggested. Courses in behavioral economics, which considers the role of “social preferences” like __60__, fairness and cooperation, are required for students of economics major. In fact, economics courses not involving some behavioral economics are considered both an inadequate education and a poor preparation to be a practicing economist. Also, __61_ width, economics majors are required to take courses in social sciences like sociology and psychology, which place considerable emphasis on how people are __62__ about others, not only themselves. __63__, within economics courses, we should do a better job __64__ the principle of self-interest, which involves anything a person values -- including helping others.

Section B
Directions: Read the following four passages. Each passage is followed by several questions or unfinished statements. For each of them there are four choices marked A, B, C and D. Choose the one that fits best according to the information given in the passage you have just read.
(A)
I used to think of myself as a fairly cosmopolitan（全球的）sort of person, but my bookshelves told a different story as my literature collection mainly consisted of British and American titles. Worse still, I hardly ever read anything in translation. My reading was limited to stories by English-speaking authors.
So, at the start of 2012, I set myself the challenge of trying to read a book from every country in a year to find out what I was missing.
With no idea how to go about this, thinking that I was unlikely to find books from nearly 200 nations from my local bookshop, I de cided to ask the planet’s readers for help. I created a blog called A Year of Reading the World, appealing for suggestions of titles that I could read in English.
The response was amazing. Before I knew it, people all over the world were getting in touch with ideas and offers of help. Some posted me books from their home countries. Others did hours of research on my behalf. In addition, several writers sent me unpublished translations of their novels, giving me a rare opportunity to read works otherwise unavailable to the 62% of British people who only speak English. Even with such support, however, sourcing books was no easy task.
Tracking down stories in some unfamiliar places even took as much time as the reading and blogging. It was hard to fit it all in around work and many were the nights when I sat bleary-eyed (睡眼惺忪的) into the small hours to make sure I stuck to my target of reading one book every 1.87 days.
Still，one by one, the country names on the list made at the start of the year transformed into vital, exciting places filled with laughter, love, anger, hope and fear. Lands that had once seemed exotic became familiar to me – places I could identify with. At its best, I learned, fiction makes the world real.
66. What help did the writer receive to achieve his goal?
A. Some writers sent him their original works.
B. The local bookstore provided books from 200 nations even if it was unlikely.
C. Some writers did research work on what books are popular.
D. Some people mailed books from their own countries.
67. In order to accomplish his goal, the writer did the following except ______.
A. asking for help from all over the world
B. making full use of his leisure time after work
C. reading until early next morning
D. appealing to writers to send him new books
68. What does the word "exotic" in the last paragraph most probably mean?
A. Unrealistic.
B. Uncivilized.
C. Strange.
D. Unimaginable.
69. Which of the following best describe the writer’s experience in the year?
A. Original but tiring
B. Hard but relaxing
C. Busy but fruitful
D. Helpful but challenging

(C)
Have you ever seen harmful robots refuse to die, no matter how fiercely people fight back? As is known, it is always the case in some of the scariest science fiction.
Now, science fiction has changed into science fact. For the first time, researchers have created a robotic machine that can stand a beating and keep on walking. Developed by scientists from Cornell
University and the University of Vermont, the new robot looks like a spider with four legs. Until now, even the most advanced robot was almost certain to break down when damaged. That’s because its inside computer simply doesn’t know how to operate the machine after its shape has changed.
To get around this problem, the spidery robot’s developers equipped their invention with eight motors and two sensors that read how the machine is tilting(倾斜). The motors and sensors all provide electrical signals to the machine’s software.
Using this information, the system follows a new procedure to figure out the machine’s shape at any given moment. The program chooses from among 100,000 possible arrangements of parts.
From there, the computer considers a wide variety of possible next steps, and it calculates how best to move the robot forward the longest possible distance, before trying to move again.
“The new strategy is a major advance in robotics”, Professor Skehan, a scientist in Cornell University says, “and it’s far from scary.” The technology may someday help researchers create better artificial arms and legs that give new freedom to people who lack them. The new knowledge might also help scientists understand how people and animals figure out their own sense of place in space.
“Designing robots that can adapt to changing environments and can compensate(补偿) for damage has been a difficult pro blem,” says neuroscientist Olaf Sporns of Indiana University in Bloomington. “This work provides a new way toward solving this important problem.”
74. The purpose of the author to write this article is to ________.
A. introduce a new robot that will not die
B. discuss science fiction and new invention
C. recommend the latest invention
D. explain the relationship between robot and medicine
75. It can be learnt from the passage that ________.
A. animals have no sense of place in space
B. people have difficulty in figuring out how to get to his destination
C. scientists don’t understand people’s ability of location
D. scientists want to know where people and animals are going
76. What’s the most important characteristic of the new robot?
A. Its shape is like a spider with four legs.
B. It can repair itself and move again after damaged.
C. It is operated by its inside computer.
D. It is certain to change the direction when damaged.
77. We can infer from the view of Professor Skehan that ________.
A. the new technology will help people have a better sense of space
B. the new technology will help people grow new arms and legs
C. designing robots can help to be adaptable to the changing of the environment
D. the new technology will have some medical benefits
Section C
Directions: Read the passage carefully. Then answer the questions or complete the statements in NO MORE THAN TEN WORDS.
With 26 British prime ministers, 58 Nobel prize winners, over 150 Olympic medals and a "notable alumni" list that reads like a historical hall of fame, the institutions of Oxford and Cambridge – collectively known as Oxbridge – are seen, by many, as the dream alma mater(母校). However, as admission season dawns, and the October 15 deadline for Oxbridge inches ever closer, many students may wonder what makes the UK's top two institutions so special. Why does Oxbridge symbolize the academic dream for so many? Do the universities deserve the reputation they hold in the minds of so many teenagers, parents and academics?
There is no doubt that both Oxford and Cambridge have a long standing history of academia. Yet, what is often overlooked is the strong reputation of countless other universities in the UK.
A simple click on Google can tell students that the London School of Economics and Political Sciences, for example, has over 18 Nobel Prize winners and 50 world leaders. University College London attracts students from 150 countries and has exchange and research links with nearly 300 overseas universities. Manchester University has the largest student union of all UK universities and boasts alumni such as Niels Bohr and James Chadwick.
I suddenly realized the Oxbridge effect when I was out in London with friends. I met some new people and was surprised by their reaction when I told them I was going to study at Cambridge. One person even got down on one knee and kissed my hand.
From then on, I told people I was going on a gap year. Although I knew that Oxbridge provides a good education, I had never expected to get such extreme reactions. It was this that made me start to feel uncomfortable about the way that Oxbridge is viewed.
The Cambridge Tab, the university's student newspaper, has argued that what makes Cambridge special is the fact that the students are told that they are unique and a cut above the rest, so they believe it. Ron Weasley never took the Felix Felicis potion that Harry Potter pretended to give him – all he had to do to win the Quidditch match was to believe he was great.
For students applying now, yes, you will receive a world class education at Oxbridge, but you will find the same at numerous other universities throughout the country. Every time you hear about the brilliance of Oxbridge, consider that just because many believe, it does not have to be so.
78. The examples of the London School of Economics and Political Sciences, University College London and Manchester University serve to illustrate the point that ______________in the UK. 79. According to the passage, we can find that people ___________________ the students at the Oxbridge.
80. How did the writer avoid over-reaction from people to her admission into Cambridge?
______________________________________________________________________
81. What is the writer’s suggestion to students applying to universities?
_______________________________________________________________________

一、阅读（60分） （一）阅读下文，完成第1-5题。（11分） 我和我的建筑都像竹子 贝聿铭 ①在长达70年的建筑设计生涯中，我先后设计规划了法国卢浮宫博物馆，美国国家艺术馆东楼、肯尼迪图书馆等建筑，大部分作品都与文化艺术有关，符合了自己的追求。 ②有人说一个设计师的命运75%来自他招揽生意的能力，我不同意。建筑师不能对人说：“请我吧！”自己的实力是最好的说服工具。怎么表现你的实力？那么就要敢于选择，敢于放弃，决定了的事情，就要有信心进行下去。 ③64岁，我被法国总统密特朗邀请参加卢浮宫重建，并为卢浮宫设计了一座全新的金字塔。当时法国人高喊着“巴黎不要金字塔”、“交出卢浮宫”，不分昼夜表达不满，翻译都被吓倒了，几乎没有办法替我翻译我想答辩的话。当时的确有压力，我面对的是优越感极为强烈的法国人，卢浮宫举世闻名。做事情最重要的是维持十足的信心，必须相信自己，把各种非议和怀疑抛诸脑后。旁人接受我与否不是最重要的，我得首先接受自己。建筑设计师必须有自己的风格和主见，随波逐流就肯定被历史淹没了。 ④后来金字塔获得了巨大的成功，我也被总统授予了法国最高荣誉奖章，但我仍然保持一贯的低姿态，说：“谦恭并不表示我有丝毫的妥协，妥协就是投降。” ⑤这么多年，我敢说，我和我的建筑都像竹子，再大的风雨，也只是弯弯腰而已。 ⑥我生在中国，长在中国，17岁赴美国求学，之后在大洋彼岸成家立业。但中国就在我血统里面，我至今能说一口流利的普通话，平时的衣着打扮，家庭布置与生活习惯，依然保持着中国的传统特色。越是民族的，越是世界的。当然美国新的东西我也了解，中美两方面的文化在我这儿并没有矛盾冲突。我在文化缝隙中活得自在自得，在学习西方新观念的同时，不放弃本身丰富的传统。 ⑦“志于道，据于德；依于仁，游于艺”，建筑不是服装，可以赶时髦，建起来以后，不能说明年不流行了就立刻拆掉。我从来不赶时髦，我比较保守；但我也从来不把自己定位成古典或者现代派。还有人称我是现代主义大师，相当多的作品都是西式建筑，但在设计方面我力争把古典和创新相结合，并且摸索新路改进自己的风格。 ⑧我曾受邀在日本东京的静修中心建造一个宗教的钟塔，这座钟塔的形状很像日本一种传统乐器：底部是方的，往上逐渐变平变扁，越往顶端越锋利。日本人很喜欢，后来再次邀请我为博物馆做设计。当我还是孩子的时候，读过一个中国故事叫《桃花源记》，很羡慕那种生活安然，环境优美的感觉。日本人知道这个故事，都说，对，要是能把博物馆做成那种感觉就好了。博物馆选在山上，在山上修了一座桥，穿过山谷通向博物馆。日本人非常接受这个设计。
