可我在游泳时总感到胸口和耳朵有压迫感，特别是刚跳进游泳池的时候感觉最明显。于是我就问爷爷：“这是为什么？”爷爷说：“这是水的压力造成的。水的压力大小与水的深度有关系，水的压力会随着水的深度增加而加大，使人的胸部和耳朵感到有压迫感。”我听了后还是感到不太理解，于是，爷爷做了一个实验：
他拿了一个大的可口可乐塑料瓶，在瓶子的底部、中部和上部分别钻了3个小孔，并用橡皮塞子把三个小孔堵住，他又给瓶子里装满了水，然后分别取掉橡皮塞，这时从三个孔中流出的水显然不一样。从底部流出的水喷射得最远，其次是中部的水，喷得最近的`是从上部喷出的水。这个实验使我明白了：随着水的深度不同，水产生的压力也就不同。我在水中越深，胸口和耳朵感到的压力就越大，水浅了，压力也就小了。
在《游泳与健康》中我又查到：因为水的密度比空气大800余倍，据测定：游泳时人的胸部要受到12?15公斤的压力，加上冷水的刺激，肌肉的紧缩，呼吸就会感到困难，这就迫使人要用力呼吸，加大呼吸深度，这样才能使吸入的氧气量满足机体的需求，这也是游泳者在水中感到呼吸困难的原因。所以经常游泳，可以增大呼吸肌肉的力量，提高呼吸系统的机能。最明显的例子是肺活量的值。游泳运动员的肺活量可以达到4000到6000毫升，甚至7000毫升，而一般的人只有3000到4000毫升。所以，游泳会促使人的呼吸肌肉发达，胸围增大，肺活量增加，而且吸气时肺泡开放更多，换气顺畅，对健康是极为有利的。
疑惑解除了，我对游泳更喜欢了。

Life has its ups and downs, and only true friends always stay around. Like anyone else, I have got many friends. They often help me when I’m in trouble. Especially, when I fail in an examination, they always care for me and encourage me to study harder. Last year, when I was hurt in a basketball game, my friends took me to the nearby hospital at once and look after me by turns. In my eyes, friends are the most precious wealth that one should treasure all his life.
