Why would an animal kill itself? It seems a strange question, and yet it is one that has made some scientists curious for a long time. For there is a kind of animal called lemming（旅鼠）, that periodically killed themselves together, and no one knows just why!
The small creatures which live in the Scandinavian mountains, feed on a diet of roots and special insects and live in nests they dig underground. When their food supply is large, the lemmings live a normal and undisturbed life.
However, when the lemmings’ food supply becomes too low to support the population, a singular migration（迁徙）begins. The lemmings leave their nests in groups. Great numbers of them begin to travel across the Scandinavian plains, a journey that may last weeks. The lemmings eat everything in their path, continuing their long march until they reach the sea.
The reason for what follows remains unbelievable to naturalists. Upon reaching the coast, the lemmings do not stop but swim by the thousands into the sea. Most stay afloat only a short time before they tire, sink and drown.
A common theory for this mass self-killing is that the lemmings do not realize that the ocean is such a huge body of water in their cross-country journey, the animals must cross many smaller bodies of water, such as rivers and small lakes. They may think that the sea is just another such swimmable path to go through. But no final answer has been found to the strange happening. The passage is mainly about______.
| A．how lemmings find food |
| B．why animals kill themselves |
| C．the lemmings’ self-killing |
| D．the food supply in the Scandinavian mountains |
A reason for the lemmings’ self-killing might be that they______.
| A．go mad from a lack of food |
| B．hope to find fish for food |
| C．decide to reduce the population |
| D．think they can cross the sea |
Why are scientists curious about the lemmings’ behavior?
| A．Because they are the only animals that live in Scandinavia. |
| B．Because it is very unusual for animals to kill themselves. |
| C．Because of the amount of food they can eat on their march to the sea. |
| D．Because they can gather together in such huge numbers. |
The underlined word “singular” means______.
| A．unusual | B．single | C．wonderful | D．common |
In 1947 a group of famous people from the art world headed by an Austrian conductor decided to hold an international festival of music，dance and theatre in Edinburgh.The idea was to reunite Europe after the Second World War.
It quickly attracted famous names such as Alec Guinness，Richard Burton，Dame Margot Fonteyn and Marlene Dietrich as well as the big symphony orchestras(交响乐团)．It became a fixed event every August and now attracts 400,000 people yearly.
At the same time，the “Fringe” appeared as a challenge to the official festival.Eight theatre groups turned up uninvited in 1947，in the belief that everyone should have the right to perform，and they did so in a public house disused for years.
Soon，groups of students firstly from Edinburgh University，and later from the universities of Oxford and Cambridge，Durham and Birmingham were making the journey to the Scottish capital each summer to perform theatre by littleknown writers of plays in small church halls to the people of Edinburgh.
Today the“Fringe”，once less recognized，has far outgrown the festival with around 1,500 performances of theatre，music and dance on every one of the 21 days it lasts.And yet as early as 1959，with only 19 theatre groups performing，some said it was getting too big.
A paid administrator was first employed only in 1971，and today there are eight administrators working all year round and the number rises to 150 during August itself.In 2004 there were 200 places housing 1,695 shows by over 600 different groups from 50 different countries.More than 1.25 million tickets were sold.What was the purpose of Edinburgh Festival at the beginning?
| A．To bring Europe together again. |
| B．To honor heroes of World War Ⅱ. |
| C．To introduce young theatre groups. |
| D．To attract great artists from Europe. |
Why did some uninvited theatre groups come to Edinburgh in 1947?
| A．They owned a public house there. |
| B．They came to take up a challenge. |
| C．They thought they were also famous. |
| D．They wanted to take part in the festival. |
Who joined the“Fringe”after it appeared?
| A．Popular writers. |
| B．University students. |
| C．Artists from around the world. |
| D．Performers of music and dance. |
We may learn from the text that Edinburgh Festival________.
| A．has become a nonofficial event |
| B．has gone beyond an art festival |
| C．gives shows all year round |

(2013·高考新课标全国卷Ⅰ，B)The baby is just one day old and has not yet left hospital.She is quiet but alert (警觉)．Twenty centimeters from her face researchers have placed a white card with two black spots on it.She stares at it carefully.A researcher removes the card and replaces it by another，this time with the spots differently spaced.As the cards change from one to the other，her gaze(凝视) starts to lose its focus—until a third，with three black spots，is presented.Her gaze returns：she looks at it for twice as long as she did at the previous card.Can she tell that the number two is different from three，just 24 hours after coming into the world?
Or do newborns simply prefer more to fewer? The same experiment，but with three spots shown before two，shows the same return of interest when the number of spots changes.Perhaps it is just the newness? When slightly older babies were shown cards with pictures of objects (a comb，a key，an orange and so on)，changing the number of objects had an effect separate from changing the objects themselves.Could it be the pattern that two things make，as opposed to three? No again.Babies paid more attention to squares moving randomly on a screen when their number changed from two to three，or three to two.The effect even crosses between senses.Babies who were repeatedly shown two spots became more excited when they then heard three drumbeats than when they heard just two；likewise (同样地) when the researchers started with drumbeats and moved to spots.The experiment described in Paragraph 1 is related to the baby’s________.
| A．sense of hearing | B．sense of sight |
| C．sense of touch | D．sense of smell |
Babies are sensitive to the change in________.
| A．the size of cards | B．the colour of pictures |
| C．the shape of patterns | D．the number of objects |
Why did the researchers test the babies with drumbeats?
| A．To reduce the difficulty of the experiment. |
| B．To see how babies recognize sounds. |
| C．To carry their experiment further. |
| D．To keep the babies’ interest. |
Where does this text probably come from?
| A．Science fiction. |
| B．Children’s literature. |
| C．An advertisement. |
| D．A science report. |

Being able to call on the old boy's network helps you get your foot in the door，but has little impact on your later success.Having good connections does change your possibility of being offered a higher wage when you start working，but has no impact on your eventual wage.Coming from a wealthy background has little impact on lifetime earnings.Over time，brain power soon overtakes(超过)，and intelligence is the factor，which will determine your earnings and success.The speed of your rise through the ranks is determined largely by your own intelligence.
The study monitored earnings and promotions over the course of 25 years.Scores were used to assess the SocioEconomic Background(SEB)－wealth and connections－and standard Army intelligence tests used to assess intelligence.The study is sure to infuriate(激怒)those angered by wealthy groups such as Oxford's upper－crust(上流社会)Bullingdon Club，of which both David Cameron and Borris Johnson were members.
Professor Yoav Ganzach says that these findings have a positive message for those，who can't rely on nepotism(裙带关系)for their first job.“Your family can help you start your career and you do get an advantage，but it doesn't help you progress.And once you start working，you can go wherever your abilities take you，” he says.When intelligence and SEB are pitted directly against once another(相互较量)，intelligence is a more accurate predictor of future career success，he say.How many factors which may influence one's career are mentioned in the passage?
| A．1. | B．2. |
| C．3. | D．4. |

The breaking news of Mo Yan's Nobel Prize in Literature on Thursday evening soon aroused public curiosity of the 57yearold Chinese writer: Why was it him that was favored by the Swedish Academy?
Born in 1955 into a rural family，Mo dropped out of school and became a farmer when he was a teenager.He joined the military and devoted himself to writing after the Cultural Revolution (1966－1976)．
Less than half an hour after the announcement，Mo's works turned to soldout status at China's major online book sellers.One lucky buyer wrote in an online comment: “Rushed to purchase，but to my shame，I have not read any of his novels.”
Although Mo was entitled one of the top domestic literature awards before the Nobel Prize，he is not the most popular novelist in China，in either the book market or in reputation.
Mo's novel “Big Breasts & Wide Hips，” translated by Howard Goldblatt，tells a story of a mother who struggled and suffered hardship and intertwined fates with Chinese people in the 20th century.His more recent work “Frog” more directly criticized China's onechild family policy，which helped control the country's population explosion but also brought tragedies to rural residents in the past 60 years.
“I think the reason why I could win the prize is because my works present lives with unique Chinese characteristics，and they also tell stories from a viewpoint of common human beings，which is above differences of nations and races，” Mo said on Thursday evening to Chinese journalists.Mo also said many folk arts originated from his hometown，such as clay sculpture，paper cuts，traditional new year paintings，have inspired and influenced his novels.
With more Chinese writers like Mo，the world could learn a more real China.Perhaps，this is another reason for the Swedish Academy's choice.What can we conclude from the second paragraph?
| A．Mo's life experiences. | B．Mo's family life. |
| C．Mo devoted himself to writing. | D．Mo had a gift for writing. |
What can we infer from the passage?
| A．Mo didn't got any national awards before he won the Nobel Prize. |
| B．Mo was the top novelist in China before he won the Nobel Prize. |
| C．Mo's novels have attracted many people to read. |
| D．Mo's novels are all based on his daily life. |
Which of the following have no effect on Mo's novels according to the passage?
| A．Clay sculpture. | B．Paper cuts. |
| C．Folk arts. | D．Beijing opera. |
According to the passage，we know that________．
| A．Big Breasts & Wide Hips' leading role is one happy mother |
| B．Big Breasts & Wide Hips criticized China's onechild family policy |
| C．Frog came out earlier than Big Breasts & Wide Hips |
| D．Frog shows benefit as well as shortcoming of one China's policy |
