A reduced adjective clause begins with either a present participle or a past participle. It's simple to know which one to use: if the reduced clause is made from an active verb, start the adjective clause with the present participle, but if it's made from a passive verb, begin the adjective clause with a past participle. For example, the ordinary adjective clause in the first example:

Example 1

Example Adjective Clause Verb in the adjective clause
I saw a man who was carrying an umbrella. who was carrying an umbrella “was carrying” is active

reduces to:

Example Reduced Adjective Clause Participle that starts the reduced clause
I saw a man carrying an umbrella. carrying an umbrella carrying

We use “carrying” in the reduced clause because it comes from the active verb in the original clause.

Example 2

Example Adjective Clause Verb in the adjective clause
The people who worked there got a raise last year. who worked there “worked” is active

This reduces to:

Example Reduced Adjective Clause Participle that starts the reduced clause
The people working there got a raise last year. working there working

Example 3

Example Adjective Clause Verb in the adjective clause
The books which were published that year are expensive. which were published that year “were published” is passive

reduces to:

Example Reduced Adjective Clause Participle that starts the reduced clause
The books published that year are expensive. published that year published
