| Option | Meaning and use | Example |
|---|---|---|
| (1) when (answer) | When links an event to a point of time: the action happened at that time. | I met her when I was in college. |
| (2) while | While and as link two actions going on over the same period. While joins two actions that go on together. Leaving for Australia is a single event, not a continuing action. | She sang while she cooked. |
| (3) since | Since marks a starting point that continues to the present and needs a perfect tense in the main clause ("has lived ... since"). "Left" is a simple past event. | I have lived here since 2010. |
| (4) as | As joins two actions happening at the same moment, or gives a reason. It does not tie an event to a stage of life such as an age. | As I walked home, it began to rain. |
