海鷗為什么追著輪船飛？（通訊員稿）

在海上航行的輪船，常常會有一群白色的海鷗相伴，從而給一望無際的大海增添了無限生機和詩意。在贊嘆之余，不禁想問：海鷗為什么總是喜歡追逐輪船呢？原來，海鷗跟著輪船可是好處多多呢！
 Many people like to go to the sea and relax, while
enjoying the waves, and the sights of ships coming and going, followed by lots
of seagulls.. Because of the combination of the ship pushing through air and the
water resistance, a current of wind develops over the ships. This tailwind lifts
up the seagulls following the ship, making it easy for them to fly without
getting tired. The ship also turns up fish and shrimp in its wake, which make an
easy dinner for seagulls, who have keen eyesight. For seagulls, following the
ships is really a smart move.
