Though not known to use tools in the wild, the birds have proved skilful at tool use while kept in the cage. In a recent experiment, cockatoos were presented with a box with a nut inside it. The clear front of the box had a“keyhole”in a geometric shape, and the birds were given five differently shaped“keys”to choose from. Inserting the correct“key”would let out the nut. In humans，babies can put a round shape in a round hole from around one year of age，but it will be another year before they are able to do the same with less symmetrical（对称的）shapes. This ability to recognize that a shape will need to be turned in a specifi c direction before it will fi t is called an“allocentric frame of reference”. In the experiment, Goffi n’s cockatoos were able to select the right tool for the job, in most cases, by visual recognition alone. Where trial 　and 　error was used，the cockatoos did better than monkeys in similar tests. This indicates that Goffi n’s cockatoos do indeed possess an allocentric frame of reference when moving objects in space, similar to two year old babies. The next step, according to the researchers, is to try and work out whether the cockatoos rely entirely on visual clues（线索）, or also use a sense of touch in making their shape selections.（词汇积累：frame n. 框架；visual adj. 视力 的，视觉的；trial and error反复试验；possess vt. 拥有；reference n. 参考， 说到； rely on依靠，信赖） T h o u g h n o t k n o w n . . .和w h i l e kept是状语从句的 省略 长 难 句 分 析 ： 本句是一个长难句。 recognize后是that引导 的宾语从句，before引 导 的 x1 状 语从句。 同位语 {#{QQABKYCUogCAAAJAAQgCUwWQCkGQkAEAACoOxAAAIAIAAAFABAA=}#} 445   第三部分    主题语境篇 1.
