Some Australian scientists put up different cards with an odd or even number of triangles ()Then they trained the first group of bees to choose odd numbers and the second group to choose even numbers.Bees got sugar water for right choices and got bitter water for wrong ones. Soon,all bees learned to tell odd/even numbers,choosing correctly 80%of the time. Later,scientists added new cards with 11 and 12(never seen in training),but bees still chose right 70%of the time.Surprisingly,bees even learned numbers more quickly than people. Scientists don't know how bees learn so quickly,but they think finding the answer could help build better,faster computers-especially since a bee's brain is smaller than ours! 1.新考法推断文章开篇方式How does the passage start?
