Middle English

中古英语

from Old English an, on * see an-

源自 古英语 an, on *参见 an-

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。

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 。

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。

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。

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。

On.See Usage Note at on

同“on ”参见 on

没有都是一样的onto (on to)一 . 在涉及到水平面高低变化的移动时，可以用onto，但这主要用于人和动物： People climbed onto their roofs． 人们爬上自己家的房顶。 We lifted him onto the table． 我们把他抬到桌上。 The cat jumped onto the mantelpiece． 猫跳到了壁炉台上。 二 . onto同时含有on和to的意思，它表示某一事物向某一“平面”、“线”或“点”运动，并“着落”、“接触”在其上面，通常译为“到……上”。在美国英语里一般用onto这样的形式，在英国英语里则以“on to”为佳，这里的“on to”是复合介词。此外，在非正式的场合，onto还有“了解”、“挑剔”、“认识”、“注意”等意思。A.“到……上”例如：He was never systematic about his paper; they piled up on his desk and work table and oveflowed on to the floor.They tried to put the blame on to me.Note:1. on也可以被用作onto的意思，表示“由运动而接触”。如：He finally got on (=onto) the horse.但用onto时常常强调“作这种运动的努力”。另一方面，如果要强调运动的方向，比如与from连用时，也必须用onto。例如：Water splashed down from the roof onto my hat.2. 在英国，into常写成on to，这里的on和to 构成复合介词，它们之后仅接一个介词宾语。如climb on to the box。但有时候on是副词，用来修饰前面的动词，在这种情况下on与to已不是复合介词，不能连写在一起，如：Let us go on to the next item on the agenda.3. 在副词on之后有时接不定式的to，这时on和to已不是复合介词，因此不能连写成onto，如：He went on to tell us of his experiences on Tibet.4. 偶尔onto也被用作on的意思，表示“静止的接触的位置”。主要用在“圆状的东西”与其它事物的接触。例如：The coat has big buttons onto it.B.“be onto sb / sth.”　　在俚语里“be onto sb.”含有“知道某人的意图”、“发现某人的错误（或非法行为）”、“挑剔某人”等意思。“be onto sth.”含有“注意到某物”、“了解某物的重要性”、“能利用某物”等。例如：He's always onto me.他老找我的岔子。I'm onto your little tricks.我知道你的鬼把戏。
