语源

用法

(1)

To indicate motion toward a position, both on and onto can be used:
表示朝某一位置的移动时,on 和 on to 都可以使用:
The cat jumped on the table.
The cat jumped on the table 。
The cat jumped onto the table.
The cat jumped onto the table。

(2)

Ontois more specific, however, in indicating that the motion was initiated from an outside point. He wandered onto the battlefield means that he began his wandering at some point off the battlefield. He wandered on the battlefield may mean that his wandering began on the battlefield. · In constructions where on is an adverb attached to a verb, it should not be joined with to to form the single word onto:
Onto更具体, 但表示的动作是从外面一点开始的。He wandered onto the battlefield 指他是从战场外面一点开始漫游的。 He wandered on the battlefield 可能意为是在战场上他开始漫游的。 当on 在结构上作为连接动词的副词时, 不应该和to 连接在一起形成一个单独的词 onto:
move on to (not onto ) new subjects;
转移到(而不是 onto ) 新的课题 ;
hold on to (not onto ) our gains. ·
保住(而不是 onto ) 我们的成果 。

(3)

In their uses to indicate spatial relations, on and upon are often interchangeable:
在用于表示空间的关系上,on 和 upon 经常可以互换:
It was resting on (or upon ) two supports.
它基于(或 upon ) 两点证明。
She took it on (or upon ) herself to finish the project.
她独立(或 upon ) 完成了项目。
We saw a finch light on (or upon ) a bough.
我们看到树枝上停着(或 upon ) 一只麻雀。

(4)

To indicate a relation between two things, however, instead of between an action and an end point, upon cannot always be used:
但在表示两件事物之间的关系而不是表示一种行为和行为终点之间的关系时,upon 不总是能被使用:
Hand me the book on (not upon ) the table.
帮我把书放在(而不是 upon ) 桌子上。
It was the only town on (not upon ) the main line.
这是(而不是 upon ) 主要干线上唯一的城镇。

(5)

Similarly, upon cannot always be used in place of on when the relation is not spatial:
同样,当两者之间关系不是空间上的关系时,不总是能用upon 代替 on :
He wrote a book on (not upon ) alchemy.
他写了一本有关(而不是 upon ) 炼金术的书;
She will be here on (not upon ) Tuesday.
她(而不是 upon ) 星期二要来这里。

To indicate motion toward a position, both on and onto can be used:
The cat jumped on the table.
The cat jumped onto the table.

(2)

Ontois more specific, however, in indicating that the motion was initiated from an outside point. He wandered onto the battlefield means that he began his wandering at some point off the battlefield. He wandered on the battlefield may mean that his wandering began on the battlefield. · In constructions where on is an adverb attached to a verb, it should not be joined with to to form the single word onto:
move on to (not onto ) new subjects;
hold on to (not onto ) our gains. ·

(3)

In their uses to indicate spatial relations, on and upon are often interchangeable:
It was resting on (or upon ) two supports.
She took it on (or upon ) herself to finish the project.
We saw a finch light on (or upon ) a bough.

(4)

To indicate a relation between two things, however, instead of between an action and an end point, upon cannot always be used:
Hand me the book on (not upon ) the table.
It was the only town on (not upon ) the main line.

(5)

Similarly, upon cannot always be used in place of on when the relation is not spatial:
He wrote a book on (not upon ) alchemy.
She will be here on (not upon ) Tuesday.
