For или since

1) I've been in Asia for seven years. - In this case, we use "for" to indicate the duration of time that someone has been in a place. - The correct usage is "for" because it indicates the length of time (seven years) that the person has been in Asia. - Example: "I've been in Asia for seven years."

2) I've worked at school since 1993. - In this case, we use "since" to indicate the starting point of an action or event. - The correct usage is "since" because it indicates the starting year (1993) when the person started working at school. - Example: "I've worked at school since 1993."

3) I've known Tom for five years. - In this case, we use "for" to indicate the duration of time that someone has known another person. - The correct usage is "for" because it indicates the length of time (five years) that the person has known Tom. - Example: "I've known Tom for five years."

4) I've been to America since July 1999. - In this case, we use "since" to indicate the starting point of an action or event. - The correct usage is "since" because it indicates the starting month and year (July 1999) when the person visited America. - Example: "I've been to America since July 1999."

5) I've not seen you for a long time. - In this case, we use "for" to indicate the duration of time that someone has not seen another person. - The correct usage is "for" because it indicates the length of time (a long time) that the person has not seen the other person. - Example: "I've not seen you for a long time."
