动作或状态的持续

the continuous aspect of an action or a state

The aspect particle “着”is placed directly after a verb to express the continuous aspect of an action or a state. For example:
我们说着、笑着。
林娜宿舍的们开着。
胳膊这么弯着。
她穿着红的旗袍。

When used in a sentence with serial verb phrases, in addition to emphasizing that the two actions in the sentence are happening simultaneously, the construction “V+着（+O）” also frequently indicates the manner of the action expressed by the second verb. For example:
我们骑着自行车回学院。
他笑着说：“应该祝贺你！”
你们还带着花儿来看我。

The negative form of this construction is “没（有） +V +着”，and its V/A-not-V/A question form is “V+着+ 没有”。 For example:
电视开着没有？
---电视没有开着。
你带着护照没有？
---我没有带着护照。
他没有躺着看电视，他坐着看电视呢。

The construction “V+ 着”is frequently used with such words such as “在”，“正在”and “呢”。 For example:
林娜躺着看电视呢。
他正在打着电话呢。
他在开着车呢。

Note that complements should not be used after the “V+ 着”construction. We cannot say “他写着汉字写十分钟”，for example.
