题型:不详难度:来源:
From the moment that an animal is born it has to make decisions. It has to decide which of the things around it are for eating, and which are to be avoided; when to attack and when to run away. The animal is , in fact , playing a very dangerous game with its environment , a game in which it must make decision—a matter of life or death .
Animals’ ability to act reasonably is believed to come partly from what we may call “genetic (遗传性的)learning” , which is different from the individual (个体的) learning that an animal does in the course of its own lifetime . Genetic learning is learning by a
species —animals of the same kind—as a whole , and it is achieved by selection of those members of each generation that happen to act in the right way . However, the role of genetic learning depends upon how similar the future environment is to the past. The more important individual experience is likely to be, the less important is genetic learning as a means of getting over the problems of the survival game. Because most animals live in ever changing environments from one generation to the next, it is not surprising to find that very few species indeed depend wholly upon genetic learning.
In the great majority of animals , their particular ways of acting in a new environment are a compound (复合体) of individual experience added to the action patterns animals are born with .That is why animals can survive.
72.The animal’s life will come to an end .
A.if the animal makes a wrong decision B.if the animal plays a dangerous game
C.when the animal attacks its enemy D.when the animal runs too slowly
73.Very few species depend entirely on genetic learning because .
A.each generation has its own way of learning
B.their environments change all the time
C.they can act reasonably on their own
D.it takes their whole life to learn
74.When the environment doesn’t change much, .
A.animals cannot act in a right way
B.genetic learning is less important for animals
C.individual learning plays a less important role
D.animals cannot get over problems on their on their own
75.Animals’ living on generation after generation depends on .
A.their natural action pattern with their own experience
B.the lessons they have learnt during their lifetime
C.their experience in particular environments
D.the knowledge passed on by their parents
答案
72.A 73.B 74.C 75.A
解析
72.解析:根据第一段最后一句“...must make decisions-a matter of life or death”可知如果选择错了就会死掉。
73.解析:这是一道细节题。根据“...animals live in ever changing environments...it is not surprising to find that very few species indeed depend wholly upon genetic learning”这句可知多数动物都生活在一直变化的环境中,所以很少有生物完全依赖遗传性的学习。
74.解析:因为遗传性学习的作用依赖于环境变化程度,所以环境变化小,那遗传性学习作用就大。
75.解析:这是一道推断题。根据最后一段“...are a compound of individual experience added to the action patterns animals are born with.That is why animals can survive.”可知物种的生存依赖于本能和生存经验。

Collections were the inspiration(灵感) for a project at Thomas Tallis School, which formed part of the Imagine Children"s Literature Festival last autumn. Each child (aged 12-13) beautified a box and wrote a story on the subject of collections to throw inside it. The boxes were spread within the Royal Festival Hall"s Ballroom. Some were left empty to encourage visitors to write their own stories.
The subject chosen by Lauren was an imaginative one. "It"s a sort of Cinderella (灰姑娘) story," she told me, inspired by a collection of letters from her cousin, In the story these become love letters, burned by a cruel stepmother. Lauren"s best friend Charlotte is the stepmother. "I"m in Charlotte"s story too," says Lauren, "and I get run over." Charlotte"s tale was inspired by the girls" coin collection. "We"ve collected foreign coins for years – since our families went on holiday to Tenerife." she explains. "That was before the Euro, so we put pesetas in." Lauren continues: "I find a coin in the road, go to get it and get run over. I"m in hospital and then I die." Charlotte adds: "Or she might not die. I haven"t decided yet."
Millie Murray, who is a teen-novel author, thinks that setting the subject of collections was a useful inspiration to their creativity rather than a restriction(限制). "In the beginning I thought, "Will the children be able to do it?"she says. "But it"s been fruitful. Some have their own collection, some have parents who do, and some have written complete stories. It"s made them think about something they wouldn"t have otherwise, which can only be a good thing."
59. What were the children asked to do in the project?
A. To meet friends at Thomas Tallis School. B. To write stories on the subject of collections.
C. To encourage visitors to write their own stories.
D. To have their friends for characters in the stories.
60. The underlined word "pesetas" in Paragraph 2 is a kind of _____.
A. story B. collection C. inspiration D. foreign coin
61. From the stories by Lauren and Charlotte, we know that _____ .
A. Charlotte hurt herself when getting a coin
B. both of them developed their imagination
C. both of them will die in each other"s stories
D. Lauren"s cousin posted her some love letters
62. Millie Murray thinks ________.
A. collections could inspire writing creativity
B. it was good for parents to have collections
C. inspirations were very useful in writing stories
D. setting collection subjects restricted inspirations
From Mr. Ward Hoffman.
Sir, I was halfway through Professor Raj Persaud"s article “What"s the tipping point"(Financial Times Weekend, April 9-l0) when it occurred to me that what I was reading was not ironic(讽刺的). If Prof Persaud wants to know why Americans tip in restaurants, he need only ask the first American he meets in London.
Americans tip in restaurants for one reason, and one reason only: we tip to supplement (补贴) the salary of restaurant workers. Quality of service does not enter into it, beyond the fact that one may tip a bit less for poor service, or a little more for good service.
Not tipping at all in a non-fast-food restaurant is not a choice. In the US, one used to tip about 15 per cent for dining in a family-style restaurant or in an upmarket (高档的) restaurant. Here, in San Francisco Bay area restaurants, we are encouraged to tip 20 per cent or more, to help restaurant workers live in this very expensive area.
After eating at an Italian restaurant in my city, I left a tip of 20 per cent on the non-tax part of our dinner bill. It was expected. There is nothing more complicated (复杂的) than that about Americans tipping in restaurants.

From Mr. Philip McBride Johnson.
Sir, I agree with most of Raj Persaud"s opinions about the doubtful value of tipping, but with one exception(例外). Tips can be very useful when one is a repeat customer or diner.
It is only when the tipper is a stranger and likely to remain so that the system does not work to his or her advantage. But frequent a hotel or a restaurant, always tip a bit more, and the difference in service and treatment will be easily felt.
Philip McBride Johnson,
Great Falls, VA 22066, US
68. What can we learn from Hoffman"s letter?
A. Quality of service determines tipping in the US.
B. Americans don"t tip in non-fast-food restaurants.
C. Tipping in US upmarket restaurants is unnecessary.
D. How to tip in the United States is not complicated.
69. Johnson"s letter shows ________.
A. a stranger in a restaurant is likely to tip a bit more
B. diners receive better service if they frequent a restaurant
C. repeat diners may get good service if they tip a bit more
D. the tipping system works to the advantage of new customers
70. From the two letters, we can learn Professor Raj Persaud ______ .
A. feels doubtful about the value of tipping
B. believes tipping improves quality of service
C. wants to ask Hoffman about tipping in the US
D. thinks tipping a bit more one can get good service
71. The two letters most probably appears in a ______.
A. notice B. handbook C. book review D. newspaper
Being considered a leader in our society is indeed of high praise. Leadership means power, commands respect and, most important, encourages achievement. Unlike vitamin C, leadership skills can"t be easily swallowed down. They must be carefully cultivated.
Different from popular belief, most good leaders are made, not born. They learn their skills in their everyday lives. But which do they develop? How do they (and how can you) get others to follow?
Always give credit. Many leaders note that the most efficient way to get a good performance from others is to treat them like heroes. Giving public credit to someone who has earned it is the best leadership technique in the world. It is also an act of generosity (慷慨) that"s never forgotten.
Giving credit is more effective than even the most constructive criticism (批评) , which often hurts rather than helps. Kenneth Blanchard, the author of The One-Minute Manager, agrees. "Catch people doing something right!" he says. Then tell everyone about it.
Take informed risks. " The best leaders know that taking a risk is not a thoughtless exercise," says management adviser Marilyn Machlowitz. "Sky divers don"t go up in an airplane without checking the parachutes (降落伞) beforehand. "
Because the idea of risk also carries with it the possibility of failure, many of us usually wait for others to take charge. But if you want to be a leader, you must learn to fail - and not die a thousand deaths. Pick yourself up and start all over again.
Encourage enthusiasm (热情). "When people understand the importance of work, they lend their mental strengths," says Lee Ducat. But when they get excited about the work, all their energy gets poured into the job. That"s a great force! Is this the best way to create excitement? Be enthusiastic yourself - You will be followed by everyone.
60. The underlined word "cultivated" (paragraph 1) roughly means _______.
A. encouraged B. compared C. examined D. developed
61. The part Always give credit tells us that a leader should _______.
A. give helpful criticism B. regard others as real heroes
C. praise people for their good performances D. praise everyone
62. To be a good leader, you should _______.
A. not be afraid of any risks B. think twice before taking risks
C. try to avoid any possible failures D. know what a thoughtless exercise is
63. Which of the following can be the best title for the passage?
A. Leadership Is of Skills and Techniques B. Leadership Is Very Important
C. Not Many Can Be Leaders D. How to Be a Leader
"Have you ever been out on a boat and felt it lifted up by a wave? Or have you jumped in the water and felt the rush of energy as waves came over you?" asked Jamie Taylor of the Wave Energy Group at the University of Edinburgh. "There is certainly a lot of energy in waves," he said.
Scientists are working to use that energy to make electricity. Most waves are created when winds blow across the ocean. "The wind starts out by making little ripples (涟漪) , but if they keep on blowing, those ripples get bigger and bigger and turn into waves," Taylor said. " Waves are one of nature "s ways of picking up energy and then sending it off on a journey.
When waves come toward the shore, people can set up dams to block the water and send it through a large wheel called a turbine (涡轮机) . The turbine can then power an electrical generator to produce electricity.
"The resource is huge," said Janet Swain of the Worldwatch Institute. "We will never run out of wave power. " Besides, wave energy does not create the same pollution as other energy sources, such as oil or coal. Oceans cover three-quarters of the Earth"s surface - that would make wave power seem ideal for creating energy throughout the world, though there are some weak points yet to overcome.
Swain said that wave power still costs too much money. She also said that its effects on sea animals are still unknown. What is more, wave power could affect fishing and boat traffic.
Traditional sources of energy like oil and gas may someday run out. " Demand for energy to power our TVs and computers, drive our cars, and heat and cool our homes is rising rapidly throughout the world," Swain said. In the future when you turn on a light, an ocean wave could be providing the electricity!
64. The writer uses the two questions at the beginning of the passage to _______.
A. test the readers" knowledge about waves B. draw the readers" attention to the topic
C. show Jamie Taylor"s importance D. invite the readers to answer them
65. The underlined phrase "picking up" (paragraph 2) is closest in meaning to _______.
A. starting again B. speeding up C. gathering D. improving
66. We can make better use of wave energy if we _______.
A. shorten its journey to thousands of homes B. build more small power stations on the oceans
C. reduce the cost of turning it into electric power
D. quicken the steps of producing electricity
67. It can be inferred that some day we might not worry about ________.
A. air pollution B. our boat traffic C. our power supply D. our supply of sea fish
In 1837, the historian Carlyle made the first recorded use of the word " queue" (排队). He spoke of the French and their "habit of standing in a queue". Forty years later Paris was the best place to wait in line.
However, queuing became popular in Britain too. The Second World War was the golden age of queuing, and people joined any line in the hope that it was a queue for something to buy. This was the source of many Second World War jokes:
Shopkeeper to customer : Excuse me, miss, are you pregnant (***)?
Customer : Well, I wasn"t when I joined the queue.
Today, according to research in America, we (in Britain) can spend up to 5 years of our lives queuing- as compared to twelve months looking for things we have lost. But things may be changing. Many people no longer have the patience to stand in a queue. The law of the jungle (丛林) has begun to operate at bus stops, with people using their arms to push others out of the way.
One way to make life easier is to introduce "queue management". Customers at supermarket cheese counters can now take a ticket with a number which appears on a screen when it is their turn. And while they wait for their number, they can do a bit of shopping.
In some booking offices there is also a system telling customers how long they may have to wait before they are served.
One of the latest technical progress is the use of an electronic scanner (电子识别器) which can read all the contents of your shopping basket or trolley in just a few seconds. If these become popular, queuing in supermarkets may become a thing of the past.
But some people just like queuing. One man queued all night for Harrods famous January sale, and then returned home for breakfast at nine o" clock the next morning without going into the shop.
68. The joke in Paragraph 2 implies that the young woman _______.
A. has been waiting in the queue for a long time B. doesn"t need to stand in the queue
C. enjoys standing in the queue D. has stood in the wrong line
69. According to the passage, which of the following is true?
A. The British spend more time queuing than looking for lost things.
B. The Americans criticized the British for their way of queuing.
C. The British are always patient when they wait in line.
D. People queue only when they want to buy something.
70. The British try to solve the problem of queuing by all the following EXCEPT _______.
A. making a law to prevent queuing
B. telling the customers the waiting time
C. using numbered tickets to put the customers in order
D. checking the price of the goods customers buy with a scanner
71. We can infer from the passage that ________.
A. queue management doesn"t work well B. there is still queuing in England
C. we don"t see much queuing in Paris D. the French like queuing more than the British
