Expressing "when" with "de shihou"

In English, if we are reflecting on a past time, we often say, "when I was a child" or "when I was in school." In Chinese, this can also be expressed by using 的时候 (de shíhou).

Structure

To talk about events that happened at or during a particular time, 的时候 (de shíhou) is often used. This is simply attached to the word or phrase indicating the time:

(Subj.) + Verb / Adj. + 的 时候, ....

As time words can appear before or after the subject, you can also place the "Time + 的时候 (de shíhou)" after the subject:

Time Word + 的 时候, ....
