Hi Mkyol
I'd like to point out a few things:
- The word 'since' does not work in your sentence as it is written. It seems that you want to use the word 'since' to talk about 'from a point in the past up to now', but that doesn't work well with the verb 'started'. The start of something is usually a very short point in time and does not take place over a period of time.
- The word 'since' is usually used with the
present perfect continuous, and in that verb tense the verb is extremely connected to the present ('up to
now'). To talk about the past time when something began, you need the simple past tense, but you can't use the simple past tense (started) together with the time word 'since' as you have done.
- Using 'had had' would suggest something that was finished/ended before you 'started' -- i.e. she was no longer interested at the time you started. But that wouldn't really make much sense in your sentence. You should use the
simple present tense if your mother is still alive and still has this interest.
I would suggest rewriting your sentence in one of these ways:
If you want to talk about a time from the past up to the present, you could write it this way:
"My mother has an intense passion for education, and I have been learning English since junior high school."
If your mother is now dead, or if
all of the verbs (events/activities/states) are in the finished past, you could write it this way:
"My mother had an intense passion for education, and I started to learn English in junior high school."
I can't think of any really logical way to use had had (past perfect) in your sentence.
