Deduction of adjective clause is divided into two groups:
1) Active Voice Form: If an adjective clause is written in active voice, we omit relative pronoun and verb form is written in present participle (-ing form).
Example:
- I know Mr. Sokha who works in the bank.
- I know Mr. Sokha working in the bank.
Remember:
If an adjective clause is written in perfect tense - have, has, had + V3 + ..., we change to having + V3 +...
Example:
- I know Mr. Sokha who has worked in the bank.
- I know Mr. Sokha having worked in the bank.
2) Passive Voice Form: If an adjective clause is written in passive voice, we omit relative pronoun and verb form in changed to past participle (V3).
Example:
- I speak English which is spoken around the world.
- I speak English spoken around the world.
Remember:
a) Continuous Form: If an adjective clause is written in continuous form, we omit relative pronoun and to be.
We change (Sentence + relative pronoun + be + being + past participle + …) to (Sentence + being + past participle + …).
Example:
- I know Mr. Ratana who is being killed in the meeting. Change to
- I know Mr. Ratana being killed in the meeting.
b) Future Form: If an adjective clause is written in future form, we omit relative pronoun, will and be is changed to being.
We change (Sentence + relative pronoun + will + be + past participle + …) to (Sentence + being + past participle + …).
Example:
- I know Mr. Ratana who will be killed in the meeting tomorrow. Change to
- I know Mr. Ratana being killed in the meeting tomorrow.
c) Perfect Form: If an adjective clause is written in perfect tense - have, has, had + been + V3 +..., we change to having + been + V3.
We change (Sentence + relative pronoun + have/has/had+ been + past participle + …) to (Sentence + having + been + past participle + …).
Example:
- I know Mr. Dara who has been punished in the prison. Change to
- I know Mr. Dara having been punished in the prison.
