Sailing the oceans
1.So accomplished navigators were able to use it to plot their positio ns．熟练的领航员就能够用它来确定自己的位置。
句中accomplished是形容词，意思是“优秀的，熟练的”，作定语修饰其后的名词。Accomplished 的用法如下：已完成的; 已达到的： accomplished facts 既成事实；学识渊博的, 技术高超的, 有成就的： an accomplished cook 厨艺精湛的厨师，Judy is accomplished in English teaching. 茱蒂擅长英语教学；有教养的, 优雅的： an accomplished lady 才女
2.On a clear day especially during the summer the sailors could use the sun overhead at midday to navigate by．在晴朗的日子，尤其是在夏天，水手可以使用正午头顶的太阳来引导他们航行。
句中to navigate by作目的状语，修饰谓语动词，其中的by是介词，它的逻辑宾语是前面的the sun。类似的例句有： I have no topics to write about.
He found some pens to write with. He is not the person to get along with.
