After Form 7 graduated文法對嗎?20點

Using past perfect tense for two actions in the past,
1st verb = graduate
2nd verb = work

After I had graduated from Form 7, I worked as a sales associate for three years.

reduce the adverb clause:

After having graduated from Form 7, I worked as a sales associate for three years.

Using past perfect tense for two actions or events in the past,
1st verb of event = graduate
2nd verb of event = work

1. (adverbial clause) "After" + past perfect, (main clause) simple past
2. (main clause) past perfect, (adverbial clause) "before" + simple past

After I had graduated from Form 7, I worked as a sales associate for three years.

reduce the adverb clause:

After having graduated from Form 7, I worked as a sales associate for three years.

嚴格來說:

I didn't complete primary six / form seven.
I didn't graduate from primary school / high school.

Thank you all.

participial phrase containing a gerund:-
Having graduated;
from Form 7= S7;
Hence:-
Having graduated S7, I worked as a sales associate for three years.
It corresponds with the last sentence.

後面那句After Form 7 graduation, I worked as a sales associate for three years.
對。

It should be

After my form 7 graduation, i have been working as a sales associate for three years

如果你現在不是 sales associate, 不是剛剛停止這工作
After completing Form 7 education, I worked as a sales associate for three years.

如果你現在仍然是 sales associate
After completing Form 7 education, I have worked as a sales associate for three years.

嚴格來說:
graduate (intransitive verb) from
英: graduate from (university, college)
美: graduate from (u., c. + high school)

graduate (transitive verb) = to award a degree/diploma (S + V + O)
The college graduated 50 students last year.

I didn’t graduate from primary six. 我小學六年級未畢業
