问题 单项选择题

  当你站在海边,望着一望无际的蔚蓝色海水和一层一层涌向岸边的浪花,是否会有一种舒畅、开阔、生气勃勃的感觉

  俄罗斯生物物理学家阿拉巴特日独辟蹊径,观察研究了这一现象。他注意到,当海水在风力作用下形成海浪时,会产生人耳听不见的频率为8~13赫兹的次声波。该现象早已为人们所知晓。但是阿拉巴特日感兴趣的是,在我们人体内部究竟是什么东西能与来自大海的次声波频率相一致呢当他将注意力转向生物医学资料时。马上发现了自己想找的答案。

  原来,在人的大脑里存在各种不同的生物电流,它们可以通过脑电图记录下来。科学家们对记录下来的脑电波进行了深入的研究和分类。已知的几种生物电流节律无论在频率上还是在强度上都有很大差别,其中一种。节律的频串为8~13赫兹。真是惊人的巧合!也许,海洋次声波能在人的大恼里引起某种共振a节律能使人们表现出正常、镇静和精神泡满的状态。只要人稍激紧张、疲倦,。节律便会减弱。这时大脑中具有其他频率的一些节律就会开始占上风。

  这是否意味着人类大脑中的天然。节律具有某种对大海生活的遗传生理适应性呢或许这种遗传生理适应性正说明了人类远古祖先起源于大海吧。阿拉巴特日认为。人为激发频率为8~13赫兹的次声波完全能使人处于并保持不眠状态。这也许是生理学上又一新课题。

选出不符合本文观点的一项是()。

A.人类开发、利用大海次声波是生理学的一个新课题

B.人类大脑里频率为8~13赫兹的节律能使人精神饱满

C.人类大脑中的天然a节律或许具有某种对大海生活的遗传生理适应性

D.人脑中。节律减弱时,常常但是人在紧张和疲倦的时候

答案

参考答案:A

Adults usually do not remember most of the things that are taught by their teachers at school. But this story is one such lesson that I will never forget. Every time I drift off course, I think of this story.

It was a normal Monday morning, and my teacher was teaching us on important things in life and about devoting ourselves to what is important to us. This is how the story went:

An old man lived in a certain part of London, and he would wake up every morning and go to the subway. He would get onto the train right to Central London, and then sit at the street corner and beg. He would do this every single day of his life. He sat at the same street corner and begged for almost 20 years.

His house was dirty, and a stench (恶臭) came out of the house and it smelled terrible. The neighbors could not stand the smell any more, so they called for the police officers to clear the place. The officers knocked down the door and cleaned the house. There were small bags of money all over the house that he had collected over the years.

The police counted the money, and they soon realized that the old man was a millionaire (百万富翁). They waited outside his house expecting to share the good news with him. When the old man arrived home that evening, one of the officers told him that there was no need for him to beg any more as he was a rich man now, a millionaire.

But the old man said nothing at all; he went into his house and locked the door. The next morning he woke up as usual, went to the subway, sat at the street corner and continued to beg.

Clearly, this old man had no great plans, dreams or anything significant (有意义的) for his life. We learn nothing from this story other than staying focused on the things we enjoy doing.
