The natural time sense（天赋的时间感）

6. One of the most remarkable of nature's living clocks belongs to the fiddler crab, that familiar beach-dweller with the overgrown claw. Biologists have long known that the crab's shell is darkest during the day, grows pale in late afternoon, then begins to darken again at daybreak. This daytime darkening is valuable for protection against enemies and sunlight, and for many years it was thought to be a simple response by the crab to the sun-just as if we were to get a tan during the day and lose it at night.

6、大自然中最非凡的“活钟”之一就属招潮蟹，是人们熟悉的沙滩居民。它有着过分增长的螯，生物学家早就知道招潮蟹的壳在白天是黑暗的，傍晚时变成灰白，然后在破晓的时候又变黑。这种白昼黑化是针对敌人和阳光的有价值的自我保护，很多年以来，它被认为是蟹对于太阳光的一种简单反应，就像我们人类白天皮肤被太阳晒黑，晚上又会白回来。

7. But when an enterprising scientist placed a fiddler crab in darkness, he was amazed to find that the color of the crab's shell kept ticking off the time with the same accuracy.

7、但是，当一个勇于探索的科学家把招潮蟹放在黑暗中，他惊讶的发现蟹壳的颜色依然准确的按时间转变。

8. Yet another startling fact was revealed: the crab's shell reached the darkest color about 50 minutes later each day. There was a second clock inside the crab, for the tides also occur 50 minutes later from day to day. Moreover, even when the crabs were taken from the beach and put back in the dark, they continued their tidal rhythm. More research disclosed that a crab from Cape Cod, Massachusetts, reached its darkest color four hours earlier than the one taken from a beach on a neighboring island. The tides on the nearby island were found to be exactly four hours later than the Cape Cod tides.

8、人们还发现了另一个令人惊愕的事实：蟹壳的颜色变得最深的时间每天推迟50分钟。显然在蟹的身体里存在着第二只钟，因为潮汐进退的时间恰恰也是一天比一天推迟50分钟。而且，即使把蟹从海滩上带回来放在黑暗中，它们仍然保持它们的潮汐节奏。更进一步的研究发现，来自马赛诸塞州CAPECOD的蟹达到它最深颜色的时间，比来自于邻岛的蟹早4个小时。同时观察出，邻岛的潮汐极其准确地比CAPECOD的潮汐晚了4个小时。

9. Ants don't carry calendars around with them any more than fiddler crabs possess real wrist watches. But ants show amazing accuracy as to the day of the year. Each year, an ant nest sends out winged, young queens on mating flights. Hundreds of them may fly out of a single nest in the soil. Last summer, at the crest of my mountain, I watched an ant city prepare to send forth its young queens. At the precise moment that they took wing, a colony of the same species that my wife was watching near the bottom of the mountain, also sent its queen on a wedding flight. There was, of course, no way could the two colonies have checked take-off time with each other.

9、蚂蚁不可能随身携带日历就像招潮蟹不可能带着真正的手表一样。但是蚂蚁对一年中的特定一天有着惊人的精确判断。每年，每一个蚁巢都会送出带翅膀的、年轻的蚁后进行交配飞行。上百个这样的蚁后有可能从土中的同一个蚁巢飞出。去年夏天，在我家的山顶，我看到一个蚁巢准备放出它们的年轻蚁后。在它们起飞的同一个精确时刻，由我的妻子负责观察的山脚附近的另一窝同种的蚁族，亦放出它们的蚁后举行飞行婚礼。显然，这两个蚁群根本没有办法校对彼此的起飞时间。

10. Entomologist Albro T.Gaul once jotted down in his notebook that a particular species of ant in northern Massachusetts began its wedding flight at a certain day and time. He later learned that another entomologist in New Jersey, 260 miles away, observed a wedding flight by the same species of ant, on the same day, and at exactly the same time! This split-second timing is not always the rule. However, most flights take place within a definite period of time.

10、有一次，昆虫学家AlbroT、Gaul先生在他的笔记本里匆匆记下，在马赛诸塞州北部某种蚂蚁开始举行飞行婚礼的准确“日”和“时”。他后来知道，在260英里以外纽泽西州另一个昆虫学家也观察到同一种类蚂蚁举行飞行婚礼的时间，竟和他记录的在同一天、同一个时刻！这种分割到秒的记时并不总是有规律的。总之，绝大多数的飞行婚礼开始时间在一个确定的时间段里。
