Study is our student's personality.But many students will ask, why we must learn knowledge. Is knowledge so important to us?If we don't need to pass the exam, should we still need the knowledge?
As I am concerned, study is not only a personality of students, but also a personality of all people throughout their lives.People need to learn the knowledge whoever they are.If people don't learn knowledge, there will have no way to do things and become ignorant about world.Can you imagine a world that no people have knowledge?Leaving knowledge,the world would no get progress.If people don't learn knowledge, there will be no people to know how to use the computer ,how to write the news, even how to communicate with others.
So learning knowledge is a very important thing, it consists of our world.

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。

Why students can't help wearing expensive things which are famous brands?
The reason why they prefer to wear expensive clothes is just for face. Some students thought the more expensive they wear, the more confident they are. Only wearing brand clothes can they become proud. Some students are afraid to looked down if they don't wear brands things. It is easy for students to compare what they wear.
As far as I am concerned, I don't agree that students pursue famous brand. Most students can't earn money by themselves. We can't waste the money to buy expensive things which are not useful. It is hard for parents to make money. Remember, the main task of the students is to study.
