Most children at the tender age of six or so are full of the most impractical schemes for becoming policemen, firemen or train drivers when they grow up. When I was that age, however, I could not be bothered with such mundane ambitions, I knew exactly what I wanted to do.
I was going to have my own zoo. At the time, this did not seem to me, and still does not seem, a very unreasonable idea. My friends and relatives, who had long found me strange because I showed little interest in anything that did not have fur or feathers, accepted this as just another manifestation of my strangeness. They felt that, if they ignored my often-repeated remarks about owning my own zoo, I would eventually grow out of it.
As the years passed, however, to the bewilderment of my friends and relatives, my resolve to have my own zoo grew increasingly stronger, and eventually, after going on a number of expeditions to bring back animals for other zoos, I felt the time was ripe to acquire my own.
From my latest trip to West Africa, I had brought back a considerable collection of animals which were living, temporarily I assured her, in my sister’s suburban garden in Bournemouth. After a number of unsuccessful attempts to convince local councils in various areas to support my plans, I began to investigate the possibility of starting my zoo on the island of Jersey in the English Channel.
I was given an introduction to a man named Hugh Fraser who, I was told, was a broad-minded, kindly soul. He would show me around the island and point out suitable sites. So, I flew to Jersey and was met by Hugh Fraser who drove us to his family home, probably one of the most beautiful old houses on the island. There was a huge walled garden with lots of outbuildings all built in the beautiful local stone which was the colour of autumn leaves glowing in the sunshine. Turning to my wife, I said, “What a marvelous place for a zoo!”
If my host had promptly fainted on the spot, I could not have blamed him. The thought of creating the average person’s idea of a zoo, with all the grey cement and iron bars, in such a lovely spot was horrible. To my astonishment, however, Hugh Fraser did not faint, but merely cocked an enquiring eyebrow at me and asked whether I really meant what I said. Slightly embarrassed, I replied that I had meant it, but added hastily that I realized that it was impossible. Hugh said he did not think it was as impossible as all that.
He went on to explain that the house and grounds were too big for him to keep up as a private individual, and so he wanted to move to a smaller place in England. Would I care to consider renting the property for the purpose of establishing my zoo? I could not imagine more attractive surroundings for my purpose, and by the time lunch was over, the bargain had been sealed.
The alarm displayed by all who knew me when this was announced can only be imagined. The only exception to the general chorus of disapproval was my sister. Although she thought it a mad scheme, at least it would rid her back garden of the assorted jungle creatures who were beginning to put great strain on her relationship with her neighbours.

From childhood to old age, we all use language as a means of broadening our knowledge of ourselves and the world about us. When humans first 1 , they were like newborn children, unable to use this 2 tool. Yet once language developed, the possibilities for human kind’s future 3 and cultural growth increased. Many linguists believe that evolution is 4 for our ability to produce and use language. They 5 that our highly evolved brain provides us 6 an innate language ability not found in lower 7 . Proponents of this innateness theory say that our 8 for language is inborn, but that language itself develops gradually, 9 a function of the growth of the brain during childhood. Therefore there are critical 10 times for language development. Current 11 of innateness theory are mixed, however, evidence supporting the existence of some innate abilities is undeniable. 12 , more and more schools are discovering that foreign languages are best taught in 13 grades. Young children often can learn several languages by being 14 to them, while adults have a much harder time learning another language once the 15 of their first language have become firmly fixed. 16 some aspects of language are undeniably innate, language does not develop automatically in a vacuum. Children who have been 17 from other human beings do not possess language. This demonstrates that 18 with other human beings is necessary for proper language development. Some linguists believe that this is even more basic to human language 19 than any innate capacities. These theorists view language as imitative, learned behavior. 20 , children learn language from their parents by imitating them. Parents gradually shape their child's language skills by positively reinforcing precise imitations and negatively reinforcing imprecise ones. 请在14处填上正确答案()

“THE JAZZ AGE” refers to the decade after World War I, when the nation became predominantly urban. It took its name from the rich and varied new popular music which was essentially a creation of the Negro in the city. Historians cannot agree on the origin of the word “jazz”: some say it is of African or Creole origin, and others say that it derived from the name of a musician. But there is no denying that this American form of music originated with Negroes in the first age of their migration to the city, and jazz flourished primarily because of the talent, energy, and imagination of Negroes in cities. In Europe, too, the years after World War I were an age of musical experiment. But jazz was a more democratic, more communal kind of experiment. For the old World saw developing novel forms of “art music”, of salon and concert-hall music.
