Learn how to express “have been doing something for a period of time up to now” using two types of Time Spent sentences in Chinese
1 Introduction to Time Spent Sentences
Time Spent Sentences are used in Chinese to express that someone “has been doing something for a period of time up to now”. These sentences emphasize the duration of an action that started in the past and continues to the present.
There are two main patterns for Time Spent Sentences, both using the particle 了 (le) to indicate the ongoing nature of the action up to the present moment.

Chinese Sentence: 我已经学了两年的汉语了。
Key Grammar Rules
When the verb has an object, 的 must be added between the Time Spent and the Object:
Pattern: V + 了 + Time Spent + 的 + Object
Both patterns use two 了 particles:
2 Pattern 1: S + V + 了 + Time Spent + 的 + O + 了
Pattern 1 is used when you want to emphasize how long an action has been performed on a specific object. This structure clearly connects the duration with both the action and its object.
The key feature is the use of 的 (de) between the time expression and the object, which creates a possessive-like relationship: “two years’ worth of Chinese learning.”
Examples of Pattern 1
已经 (yǐjīng) Usage
已经 means “already” and is often used in Time Spent sentences:
