Mina is a college student in Tokyo.She writes ??? birds flying in great numbers know when to change direction.They change direction exactly the same.It's beautiful but mysterious.
Mina you might notice that these large flock don't move in precise synchrony.Instead they act more like a coarse line.That is one bird initiates the movement and the others follow one after another.If you watch the ??? patterns of a flock of birds,you can see the flock turn in sequence.Often the beginning of the flock has turned again before the end has completed the earlier turn.
Scientists aren't sure how the flock decides when to take off and when to swoop one way or another.Studies using high speed photography indicate that there's no consistent leader.Birds change position frequently,and any individual can initiate a flock maneuver.Once the maneuver starts,it travels rapidly through the flock in the wave.
Such rapid reaction is apparently possible because birds pay attention to more distant individuals in the flock.They anticipate the approaching change in direction in much the same way that human fans coordinate doing a wave at a football game.

It's difficult for me indeed.Before I can write out the whole text,I've listened for so many times that i now could not remember how long i've spent on it.But i'm really interested in English and especially listening to English.So every bit of progress can make me feel rejoiced.I believe practice makes perfect.Let's try hard together to improve English!

原稿：
JB: This is Earth and Sky, with a listener's question about birds in flight.
DB: Mina Nisiyama is a college student in Tokyo. She writes, "How do birds flying in great numbers know when to change direction? They change direction exactly same. It's very beautiful but mysterious."
JB: Mina, you might notice that these large flocks don't move in precise synchrony. Instead, they act more as a "chorus line." That is, one bird initiates a movement, and the others follow, one after another. If you watch the swirling patterns of a flock of birds, you can see the flock turn in sequence. Often the beginning of the flock has turned again before the end has completed the earlier turn.
DB: Scientists aren't sure how the flock decides when to take off and when to swoop one way or another. Studies using high-speed photography indicate that there's no consistent leader. Birds change position frequently and any individual can initiate a flock maneuver. Once a maneuver starts, it travels rapidly through the flock in a wave.
JB: Such rapid reaction is apparently possible because birds pay attention to more distant individuals in the flock. They anticipate the approaching change in direction in much the same way that human fans coordinate doing "a wave" at a football game.
自己的错误：chorus -> coarse, swirling -> swirl and，因为都放入了听力难点提示，所以对大家的听写肯定造成了一定程度的影响，不过希望大家多多原谅，我已经是尽了全力了。没办法。
Love me little! Love me long! |
