幫我翻做英文!!!!

Flying fish is clever in evade tracker.
飛魚逃避追捕者的方法很聰明
They jump up to the sky from the sea
它們從海里躍進空中
so the tracker inthe sea cannot catch them.
因此海中的敵人不能抓住它們
Although their fins can't flop in forward and backward,
雖然它們的鰭不能來回拍動
fins can help them "fly" on the sea.
卻能幫助它們在水面之上「飛」
They can "fly" about two hundred and fifteen yard once.
這種在空中的滑行一次可達215碼遠
Flying fish can "fly" is because they have some special evolution
飛魚能有這種本領，全靠一連串特別的進化
Their lower part of fins is bigger than past
它那擴大了的尾鰭下半截
so it can pat the water fifty times in a second
能夠以每秒鐘50次的頻率拍打水面
and have enough velocity for a"flying" .
為魚的起飛提供足夠的速度
The second characteristic for "flying" is the bigger pectoral fin.
另一個有助飛行的主要特徵，就是變大了的胸鰭
It is the "wing" of fish.
給飛魚當作翼來使用
On the water, the air current across the pectoral fin can make the fish "fly"
在水面之上，經過胸鰭的氣流將魚托起
so the fish can "fly" in the sky in a short time.
讓它可以在半空中短暫地滑翔
When the fish is "flying", the pectoral fin can help the fish "fly" higher.
飛行時，腹鰭也提供額外的升力
Flying fish shake their caudal fin and increase velocity
飛魚游向水面的時候，迅速地搖擺尾鰭來增加速度
until the velocity is about fourty mile
直到時速達到40英里
the fish can ready to "fly".
便可以準備起飛了
The flying fish can"fly" on the sea about some inch at ten seconds
便在離水面幾英寸之上滑翔約10秒鐘
Gravity and resistance will decrease the velocity
力及阻力令它的速度減緩
until the velocity is about twenty mile,
至時速20英里
the flying fish will jump into he water again.
魚又重新投入水中
If they are still in dangerou,
果在飛行後，仍未能擺脫危險

It can decrease the pulling force
減輕了鰭所受的拉力
and the flying fish can "fly" more easily
飛行也就比較容易
Flying fish's stomach and intestines is small
飛魚的胃腸異常細小
,dreases the height when the fish is flying.
