世界上有许多关于我们周围生命的有趣科学事件。

There are many interesting scientific events about life around us in the world.

例如,为什么人不可能睁着眼睛打喷嚏或人体中最强壮、最有力的肌肉是舌头。今天,我们将探索这些惊人的科学事件。

For example, why is it impossible for a person to sneeze with their eyes open or the strongest and most powerful muscle in the human body is the tongue. Today, we are going to explore these amazing scientific events.


你知道正常人的眼部肌肉每天平均运动10,000到15,000次吗?我们都眨眼,有的多,有的少。一般来说,成人每分钟眨眼 12 至 15 次,儿童可能更多。这样一来,一个人每天眨眼10000次以上。

Do you know that the eye muscles of a normal person move an average of 10,000 to 15,000 times a day? We all blink, some more, some less. In general, adults blink 12 to 15 times per minute, and children may have more. In this way, a person blinks more than 10,000 times a day.

人为什么要眨眼?这其实是一种生理需要。眨眼时,眼泪可以均匀地分布在角膜和结膜上,使眼球不至于干燥,还可以清除眼内的灰尘和细菌。如果不眨眼,眼球上的泪膜会很快蒸发,我们会感到眼睛干涩难受,甚至刺痛流泪。

Why do people blink? This is actually a physiological  need. When you blink, the tears can be evenly distributed on the cornea and conjunctiva, so that the eyeballs will not be dry and can also remove the dust and bacteria in the eyes. If you don't blink, the tear film on the eyeballs will evaporate quickly, and we will feel dry eyes uncomfortable and even stinging and tearing.

眨眼的次数也与人的心理状态密切相关。紧张的时候眨眼多,注意力集中的时候眨眼少。人们在使用电脑时,眨眼频率可低至每分钟3次。

The number of blinks is also closely related to people's psychological state. When we are nervous, we blink more, and when we concentrate, we blink less. When people use computers, the blink frequency can be as low as three times a minute.

水,是地球上最常见的物质之一,是包括人类在内的所有生命赖以生存的重要资源,是生物体最重要的组成部分。你相信自古以来水的年龄有3亿年吗?地球上的水刚形成的时候,不管是湖泊还是海洋,水的量都不是很大。

Water, which is one of the most common substances on earth, an important resource for the survival of all life including humans, and the most important component of living organisms. Do you believe that theage of water has been 300 million years since ancient times? When the water on the earth was first formed, no matter whether it was a lake or an ocean, the amount of water was not very large.

随着地球内部产生的水汽不断被送入大气层,地面上的水量不断增加。地球经过亿万年的演化,终于最终形成了我们现在看到的河流、湖泊和海洋。地球有46亿年,水当然有3亿年。

As the water vapor generated inside the earth was continuously sent into the atmosphere, the amount of water on the ground continued to increase. After billions of years of evolution of the earth, finally, the rivers, lakes and seas we see now are formed. The earth is 4.6 billion years old, of course water is 300 million years old.

左撇子是指书写或使用筷子的惯用手是左手的人。研究表明,左撇子约占人口的十分之一。左撇子是一种特殊的生理现象。据统计,全球每100人中就有15人用左手吃 饭,其中男性占70%。

A left-hander is a person whose dominant hand for writing or using chopsticksis the left hand. Studies show that left-handers make up about one-tenth of thepopulation. Left-handedness is a peculiar physiological phenomenon. According tostatistics, 15 out of every 100 people in the world eat with their left hand, and menaccount for 70% of them.

不列颠哥伦比亚大学查阅了南加州两个县的 987 人的死亡证明,并通过电子邮件向他们询问了受访者的亲属,他们主要是左撇子还是右撇子,他们发现右撇子的平均死亡年龄左撇子的平均年龄为 75 岁,而左撇子的平均年龄为 66 岁。右撇子的人平均多活九年。
Diana Halpens, a psychology professor at the University ofCalifornia, San Bernardino, and Stanley Colin, a researcher at the University ofBritish Columbia, reviewed the death certificates of 987 people in two SouthernCalifornia counties and emailed them After asking the relatives of the respondentswhether they are mainly left-handed or right-handed, they found that the averageage of death for right-handed people is 75 years old, while the average age forleft-handed people is 66 years old. Right-handed people live an average of nine years longer.
