1. sea的意思是“海,海洋”“海水”,是不可数名词。在sea前的专有名词前一般要加冠词the。
2. sea作“水域,波浪”“海浪”“汹涌的波涛”解时须用复数形式seas。

n.(名词)

at sea, by sea, by the sea, in the sea, on the sea

这五个短语的意思不同。其区别在于：

3.by sea的意思是“由海路”“乘船”。例如:

不知所措

sea, ocean

两词的意思不同,前者是海,后者是洋,在面积的划分上,海是洋的一部分。

sea，ocean

这两个名词均可表示“海”之意。

sea普通用词，可用复数形式表单数意义。sea所指的面积要比ocean小得多。sea也可是ocean的一部分。

ocean指把海作为一个整体，是海的总称，即海洋。

n.(名词)

知识的海洋深而广。

误 The knowledge sea is deep and broad.

正 The sea of knowledge is broad and deep.

误 We often swim on the sea.

正 We often swim in the sea.

析 “在海里游泳”是swim in the sea, at sea指在海上航行, on the sea指“在海上,在海边”。

大约四分之三的地球被海水覆盖。

误 About three quarters of the Earth is covered by seas.

正 About three quarters of the Earth is covered by sea.

析 sea表示“海水”时为不可数名词; 但当 sea 作“海浪”或“汹涌的波涛”解时多作复数。

我不懂这问题,我茫然不知所措。

误 I can't understand this problem; I'm all at the sea.

正 I can't understand this problem; I'm all at sea.

析 sea 往往和all 或completely连用,构成 be all〔completely〕 at sea的结构,表示“茫然”“摸不着头脑”, sea前面不加冠词。
