“海洋鸟”号看起来很有未来感，但事实上它可以追溯到古代航海的历史，因为这是一艘风力驱动的船只。请看本报昨日的报道：

Oceanbird might look like a ship of the future, but it harks back to ancient maritime history because it’s powered by the wind.

The transatlantic car carrier is being designed by Wallenius Marine, a Swedish shipbuilder, with support from the Swedish Government and several research institutions.

With capacity for 7,000 vehicles, the 200-meter-long vessel is a similar size to conventional car carriers, but it will look radically different. The ship’s hull is topped by five telescopic “wing sails,” each 80 meters tall. 报道中的hark back to就是“追溯到、让人想起”，例如：

I have to hark back to this question that I mentioned earlier on in order to let you understand how serious it is.

为了让你认识到情况有多严重，我还得重提一下我之前提过的这个问题。
