英语词汇tide的起源、历史背景-英语词源词典

tide. Though a sea tide is usually thought to be high or low water, anything between ebb and flood, tide really means “the fixed time of flood and ebb.” Tide was originally a synonym for time (as in eventide), so the expression “Time and tide wait for no man” is something of a tautology. The Greek navigator Py- theas observed and explored ocean tides in the third century b.c., but it wasn’t until Isaac Newton’s time that scientists widely believed that the Moon had any effect on ocean tides. The greatest tides occur in the Bay of Fundy, Nova Scotia, where there is an extreme range of 57 feet between high and low tides and 100 million tons of water are carried out of the bay twice each day.
