[填空题]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.
[单项选择]1 Play is common to the young of most mammals. Some birds play, but it is rare in cold-blooded animals such as fish and reptiles. Why some animals play, and others do not, is not entirely understood, but the most playful--such as dolphins and monkeys--are also the most intelligent and sociable. Play may seem something of a puzzle. Not only is it apparently unproductive, but it also places the participant at risk of being surprised by predators. However, there must be a good reason for play. The most widely held scientific explanation is that play allows the social behaviors of the species to be explored and learned. Other benefits include physical exercise and the learning of survival skills such as hunting. A kitten that grows up separated from other kittens becomes both a social misfit and a poor hunter, largely because it is deprived of play.
