Are People Unique?

It is human beings' pride that we are the only species on the Planet that can speak and think. However, recent research casts doubt on that common belief.

Zuberbuhler, a psychologist at St Andrews University, and his colleagues recorded thousands of calls made by Diana monkeys and noticed that the monkeys adapted their calls to change the meaning to warn one another about different situations. For example,they made a "krack" alarm call at the sight of a tiger. However,when they merely repeated calls made by other monkeys they added an "oo".

The researchers found that the same calls would be recognized by other species, like Campbell's monkeys. So they are communicating across species."And since then we have found that hornbill birds can understand these calls and they too can understand all the different meanings, said Zuberbuhler. What is also surprising is that signs of intelligence have been found in birds whose small brains were long assumed to be a complete barrier to intelligence. However,   all that is changing fast. A few years ago, Irene Pepperberg of the Massachusetts Institute of Technology taught a parrot to recognize and count up to six objects, which couldn't have been achieved if birds were unable to memorize.

Last year that was topped by Alex Kacelnik, a professor of behavioral ecology at Oxford, who discovered that crows (乌鸦) are capable of using tools in complex orders, the first time such behavior had been observed in non-humans. In an experiment seven crows successfully grabbed a piece of food placed out of reach using three different lengths of stick. Crucially, they were able to complete the task without any special training, suggesting the birds were capable of a level of abstract reasoning normally associated only with humans.

All this is powerful evidence against the idea that people are unique.

9 . It seems to me that all writers, including those brilliant ones, need encouragement particularly in their early years. I always knew I could write,but that just meant I wrote a little better than my peers. I hope that I might one day write well enough to derive income from my efforts. Oddly enough,this never occurred to me until I met a special teacher in life.

There was a kind teacher at Hyde Park High School in Chicago,who simply by concentrating her attention on me, made me believe that I might be able to master the knack of writing well enough to consider the craft as a profession. Miss Marguerite Byme taught English,which of course, involved writing skills.Whatever instruction she shared with me was exactly the same as all her other students enjoyed, but the only difference was that she encouraged me to begin the process of submitting things I was writing, in those days, chiefly poems.

To my surprise, the Chicago Tribune not only thought enough of several of my verses to publish them, but also paid me, inadvertently, the highest compliment a fledgling author can receive. The editor wrote a confidential letter to Miss Byme, asking her to see, if by any chance, one of her students, a certain Stephen Allen, might be guilty of copying. The editor's suspicions had been aroused, because he was kind enough to say, he found it hard to believe that a seventeen-year-old student could create material on such a professional level.When Miss Byme shared the letter with me, I was overjoyed! It was wonderfully heartening.

Miss Byme made me realize that I should not hide my light. This made me collect my courage to enter a writing contest. The assignment was to write an essay titled "Rediscovering America". I was literally astonished when I received a letter saying that I was the winner of the contest.The prize was a thousand dollars. My mother, at the time, was not even aware that I was interested in writing, or if she had somehow found out about it, she took little notice.When I arrived home that evening with the letter, she was indifferent and did not ask how the evening had gone.

Without encouragement, even talented students will continue to perform below expectations. For example, at the same high school, there was a teacher whose Spanish language classes I attended but from whom I unfortunately learned very little simply because of the woman's cold sarcastically critical attitude. She seemed to know nothing about nurturing students. Soon, I withdrew from her classroom literacy instruction.

Years later, I was able to repay my debt to Marguerite Byme by dedicating one of my books, Wry on the Rocks------A collection of Poems.to her. I have enjoyed a lifetime writing books and television scripts because of her urge.

10 . Why HS2 should go ahead

For the country that invented railways, Britain has shown remarkably little interest in them lately. New networks have been built around Europe in the past few decades, but the only significant stretch of ________ laid in Britain in a century is the 67-mile HS1 railway that links London to the Channel Tunnel. ________ , the country has half as much track as it had in 1963.Yet while Britain has an almost American ________ to invest in railways, its commuting(通勤) patterns are European: l0% of journeys are by rail, compared with 9% in Germany and less than 1% in America.

Britain's big ________ is that, because it has built no new high-speed lines, it runs fast intercity trains on the same track as slow commuter ones. Long ________ have to be left between slow and express trains. The need to make way for high-speed trains thus ________ the number of commuter services,and vice versa. Eight years ago,the government decided to change this by building a new 345-mile railway from London to the north of England. Though branded as High Speed 2, its principal job was to improve capacity(运输量) rather than ________ .

Rail is an increasingly significant part of the transport mix. Climate change is making carbon-efficiency even more important. At the same time, passenger numbers have gone beyond ________ . The government had expected passenger volumes to increase by 17-21% in the decade from 2011; actually, they were up by 24% within just seven years and are expected to go on ________ at a similar rate.

The benefit-to-cost ratio(效益成本比率) calculated for HS2, at around one, is hardly acknowledged. But just as the costs of big transport projects are often ________ , so are their long-term benefits. The extension to London's Jubilee tube line, ________ ,was approved with a BCR of less than one, but recent analysis suggests that it has been more like 1.75. And that includes only the profits that go directly to the railway, not the ________ consequences of the recovery of London's Docklands area, which the tube line made possible.

The main point of HS2, similarly, is its impact on the cities and towns along its ________ and beyond. Boris Johnson, the prime minister, is on a mission to promote growth in northern and western areas ________ by the country's London-centered pattern of growth. On its own HS2 won't make that happen, but doing so without a new railway would be ________ . The success of the "Northern Powerhouse" rail scheme, to link the north's big towns, depends on it.
