Question

You can’t get there other than by swimming.

You can’t get there other than by swimming. 除了游泳以外你无法到那里。
上面的句子可不可以改成下面两句？下面两句是否正确？
You can go there only by swimming.你只能靠游泳游到那边去。
You can go there no other than by swimming

Answer 1

一、关于other than的用法，需要从 other 的词性说起。该短语中，other 可以有三种词性——
1、 副词：意思是“以另一种方式”，如：
 You can't get there other than by swimming. 除了游泳，你去不了那里（你只能从水里游到那里）。
等于 You can't get there other than (go there) by swimming 的省略，其中 than 是连词，连接前后的两个平行结构 get there other 和 (go there) by swimming，即原句中的副词 other 和副词性介词短语 by swimming 是用连词 than 并列的两个同类词语。
拆分后直译为：
——You can't get there other 你不可能以其他方式到那里。
——than by swimming 与以游泳的方式（到那里）比起来。
其句子结构为：
主语：You
谓语动词：can’t get
地点状语：there
方式状语：other
比较状语：than by swimming.

更多的例句简析：

 * You can't get there other than by boat. 除了乘船, 你无法到达那里。
拆分解释：
——You can't get there other 你不能以另一种方式去那里
——than (get there) by boat 与乘船这种方式比起来

 * She performed other than perfectly. 她表演得远说不上完美。
同理：
——She performed other 她以另一种方式表演
——than (performed) perfectly. 比起以完美表演来

 * I have never known him behave other than selfishly. 我知道他一向自私自利。（副词 other 和副词 selfishly 并列，= I have never known him behave other than behave selfishly，直译为“比起自私自利地表现来，我从不知道他曾以其他方式表现”）

 * He can hardly be other than annoyed about it. 他当然只会对此感到烦恼。（用作表语表示状态的副词 other和表示状态的过去分词 annoyed 并列，= He can hardly be other than (be) annoyed about it,即“比起烦恼来，对此他几乎不会呈现其他方式”）

2、形容词：用在不定代词或“no +名词”后作后置定语，意思是“（除了）别的…”：
 Does anybody other than yourself know this? 除你本人之外还有别人知道这事吗?
等于 Does anybody other know this than yourself? 带有后置定语other的 anybody和 yourself 并列。
 * She has no close friends other than him. 除了他以外她没有好朋友。
等于She has no other close friends than him. 带有后置定语other 的宾语no close friends 和 him 并列。
 * They were given nothing other than dry bread and water for their evening meal. 他们晚餐仅仅分到干面包和水。。
等于 They were given nothing other than given dry bread and water for their evening meal. 带有后置定语 other 的宾语nothing 与 dry bread and water 并列

3、不定代词：指代别的人或别的事，用在 no other than，表示“不是别的、正是”，如：
 * It was no other than my mother. 这正是我的母亲。——代词 other 与名词 my mother 并列。（other 是名词性表语）
 * I have got no other than complain. 我得到的只是抱怨。——代词 other 和名词complain 并列。（other 作 got 的宾语）

二、关于问题中提出的三个句子可以从大结构上分析——

第一句：You can’t get there other than by swimming——
主谓语部分：You can’t get 你不能抵达那里
方式状语：other than by swimming. 除了靠游泳

第二句：You can go there only by swimming.——
主谓语部分：You can go there 你可以到达那里
方式状语：only by swimming. 只能靠游泳。

第三句：You can go there no other than by swimming——
主谓语部分：You can go there 你可以到达那里
方式状语：no other than by swimming. 正是靠游泳。

以上三个句子都表达“游泳才能到达那里”的同一个意思因此后面的两个句子也是正确的。
