Usually， the larger an animal is，（7） 　　its heart beats， since it takes more time to pump （输送） blood around（8） 　　body．Shrews， the smallest mammals（哺乳动物） ， have a heart rate of up to 1，000 bpm．Humans usually stay between 60 and 100 bpm．

This V shape allows geese to （4） 　　energy．When the front bird moves its wings up and down，the resulting force of the air lifts the next one．This continues down the line．The bird （5） 　　has the hardest job．When it gets （6） 　　．it moves behind，and another bird moves into the lead．By sharing the role，the group can travel great distances．Geese flying in a V shape can fly 70percent farther without （7） 　　than birds flying alone．

During the long flying journey，geese communicate with one another．They honk （鸣叫）to （8） 　　the birds up front to keep up the speed．They also cheer each other up （9） 　　working toward a common goal．

What have we learned from the lovely geese's experience and skills？
