97-101 Discussion about Zoology Exam
M: Now, let’s see, Professor Stone spent a lot of time talking about how animals walk and run. I remember she started by describing how humans move, and later we went over the gaits of different 2-leg and 4-leg animals: cats, camels, lizards,…
W: Wait, I think I missed the class when you read over how lizards move. At least, I don’t have any notes on it.
M: Well, we talked in class about how modern reptiles like lizards run. I think I even copy the diagram professor drew on the board. Here it is. Now look at this: lizards run with what’s called as sprawling gait, their feet are well out on either side of their body and they moved diagonally opposite feet together: the left fore foot with the right hind foot and the right fore foot with the left hind foot. They use this way of moving when they’re going slowly or quickly. When they move, they bend their body through from side to side. And they time this bending so that it increases the length of their steps.W: OK. That makes sense. But I remember reading that in general animals have evolved so that their feet are under their bodies. But I don’t see why?
M: Well, that’s because even though the sprawling gaits suit lizards pretty well, there’s a major disadvantage to this arrangement. Reptiles can’t run and breathe at the same time. They stop breathe between short burst anywhere from 2 to12 strides because when they move from side to side, the muscles of the left and right sides contract at different times. To breathe though, these muscles have to contract at the same time. Mammals don’t have this problem because they don’t move side to side. Their feet are in a different position.

這篇粗體字的部份在找了背景資料看了之後還是不太了解..
可不可以請懂的人幫我翻譯一下
1.增加每一步的長度..用time this bending是什麼意思
2.第二個粗體字則是完全不會翻了..

麻煩大家幫我一下..謝謝

And they time this bending so that it increases the length of their steps.

time v. 計時

They stop breathe between short burst anywhere from 2 to12 strides because when they move from side to side, the muscles of the left and right sides contract at different times. To breathe though, these muscles have to contract at the same time.

在走2-12步之間，他們會短暫的停止呼吸，因為他們是左右交互移動(身體)，所以左邊肌肉和右邊肌肉在不同的時間收縮。然而若要呼吸的話，這些肌肉都必須在同時間收縮。

為什麼"他們計算彎曲的時間就可以增加每一步的長度呢"

[HHC]

Sorry, I don't know.
You may want to ask someone who majored in biology.

[HHC]

我問了一個了解動物學的老美，他告訴我time在這裡比較正確的翻譯應該是「算準時間」。也就是說，lizards 要在身體彎曲的同時，伸出該伸出的那隻腳，如此配合才能跨出最大步伐。
如果伸出的腳不對，或是時間沒算準，步伐大小會受到限制、甚至原地踏步。

希望你看的懂！

謝謝上面兩位大大的解釋..
我懂了...
感恩...

請問此處的short burst anywhere是什麼意思呢
其中的burst又怎麼解釋?
我想翻成爆炸好像不太合適呢!!

Could someone give me a hand? Thanks
