Uso di 'when' per indicare il tempo
When answers the question "at what time?" It can convey the time of an actual event in the future or the past, or a nonspecific time that might occur. It can be used at the beginning of a sentence, or in the middle.
Ex: I'll do the dishes when I get home, since I know that there's quite a mess from last night's dinner that still needs cleaning.
Ex: It was snowing when I got to school yesterday, and we all sat around talking about whether we would be sent home early or not.
Ex: Matt knew that the fence needed to be fixed, so he said he would do it when he got a chance, and I believe him.
Importanza di 'before' e 'after'
Before and after convey the order of events in time, whether earlier or later. They are crucial for establishing a sequence of events, and are very important in directions of any kind. Both can be used at the beginning or in the middle of a sentence and the same comma rule of when applies here as well.
Ex: Before cleaning out the vacuum cleaner, it is very important to make sure that it is unplugged.
