and so on的意思|示意

English phrase \"and so on\" is used to indicate that there are more of the same kind of things to come. It is used to indicate that a list is incomplete, and there may be more items that could come after. This phrase is very useful in casual conversations, and it saves the speaker a lot of time by not having to list all the things in a group.

\"And so on\" can be used for both single words and groups of words. For example, if you were listing some countries in South America, you could say \"Brazil, Colombia, Peru, and so on.\" Or, if you were talking about different kinds of fruits, you could say \"apples, oranges, bananas, and so on.\" It can be used in any combination of words that refer to the same type of thing.

This phrase can also be used to describe a series of actions or events. For example, if you were talking about a long journey, you could say, \"We took the train, then the bus, and so on.\" This means that there were more types of transportation involved in the journey, but you don't want to list all of them.

In written English, \"and so on\" is usually followed by a comma. It should not be used in formal writing, as it implies that the list is not complete. In addition, it should not be used if the list is already written out in full.

So, the English phrase \"and so on\" is quite useful and can save the speaker a lot of time. It can be used for both single words and groups of words, and it can be used to describe a series of actions or events. Just make sure to avoid using it in formal writing.
