股票的价格随着市场潮涨潮落。

The price of stock moves up and down with the market.

第一条：就像月圆月缺、潮涨潮落一样，星期日=运动。顺其自然吧。

Sunday=sports. It's like the full moon or the changing of the tides. Let it be.

不仅是潮涨潮落有其本身永恒的规律，而且海平面也从来都不是静止的。

Not only do the tides advance and retreat in their eternal rhythms, but the surface of the sea itself is never at rest.

荷兰人几个世纪以来一直在不断地与大自然的潮涨潮落相抗争，不停地筑堤挖渠，将积水从低于海平面的地区抽走。

The Dutch have been fighting the rising and falling tides for centuries, building dikes and pumping water out of areas that are below sea level.
