When teaching the difference between “since” and “for,” it is important to explain their usage in relation to time. Here is a breakdown of their meanings and how they are used:
-
“Since”: - “Since” is used to refer to a specific point in time when an action or event started. - It is used with a specific time or date, a clause with a verb in the past simple, or a clause with a present perfect verb. - Example: “I have known her since 2010.” (referring to the starting point of knowing her) - Example: “He has been studying since he woke up.” (referring to the starting point of studying)
-
“For”: - “For” is used to indicate the duration of an action or event. - It is used with a period of time (hours, days, weeks, etc.), a clause with a verb in the present perfect, or a clause with a verb in the past simple. - Example: “I have been living here for five years.” (referring to the duration of living in a place) - Example: “She studied for three hours.” (referring to the duration of studying)
To further clarify the difference, you can provide additional examples and practice exercises. Here are a few examples:
- “I have been working here for three months.” (duration)
- “I have been working here since January.” (starting point)
- “He has been playing the guitar for two hours.” (duration)
- “He has been playing the guitar since he was a child.” (starting point)
You can also create exercises where students have to choose between “since” and “for” to complete sentences correctly. This will help reinforce their understanding of the difference between the two words.
Overall, teaching the difference between “since” and “for” requires explaining their usage in relation to time and providing ample examples and practice exercises to solidify understanding.
