        五月的第二个星期天，这是属于您的日子，妈妈，节日快乐!

        虽然在这里，我说什么您也不会听见，但我还是要说，妈妈，我爱您。是您给了我生命，是您让我明白人世间的道理，是您在我最需要的时候给了我最深切的关怀，也是您在平日琐碎的生活中照顾我的一切。如果我对您的爱是一滴水，那么您给予我的就是整个海洋；如果我对您的爱是春日里的一片新绿，那么您给予我的就是朗朗春天里所有温暖的阳光。“谁言寸草心，报得三春晖”，我不知用什么来报答您无私的爱。

        亲爱的妈妈，在您放飞我的时候，也请您保存我的爱，相信在离别之后不久，就会有永远的相聚。不论何时何地，您始终是我最牵挂的人，始终是我心中最圣洁最温暖的守护神，相信我始终需要您，需要您的拥抱、爱抚和关心!

        等到那一天，我学成归来，我能独立撑起一片真正属于自己的天空，妈妈，到时我会让您骄傲，并且为此而快乐!或许，你要的，也不过如此。

     The sea has always interested man. From it he can get food, minerals, and treasure.    1   But he

could not go far beneath its surface.

          2   However, he is not a fish. He must breathe air, so he can't stay under the water's surface for

any length of time. To explore deep water, man faces even more dangers and problems.

     A diver who wants to stay under water for more than a few minutes must breathe air or a special

mixture of gases.   3   He can carry a tank of air on his back and breathe through a nose and a

mouthpiece. Water weighs 800 times as much as air. Tons of water pushes against a diver deep in the

sea.   4   

     When a diver is under great pressure, his blood takes in some of the gases he breathes. As he rises

to surface, the water pressure becomes less. If the diver rises too quickly, the gases in his blood form

bubbles(气泡). The diver is then suffering from the bends(潜水夫病). The bends can cause a diver to

double up in pain.     5
