Key Points

|
We can simplify adverb clauses into participle clauses if the subject of the adverb clause and the subject of the main clause are the same.
Here are the steps to simplify:
Step 1: Eliminate the subordinating conjunction and the subject of the adverb clause. If there is an auxiliary verb, get rid of it as well.
Step 2: (1) If the verb in the adverb clause is in the active voice, convert the verb into a gerund (Ving). If the transformed verb is 'being', it can be skipped.
(2) If the verb in the adverb clause is in the passive voice, eliminate the 'be' verb.

Example 1:
When I walked down the street yesterday night, I saw James.
👉 Both the subject of the adverb clause and the main clause are “I”. Hence, we can simplify this sentence using the participle clause.
Step 1: We first remove the subordinating conjunction “When” and the subject “I” in the adverb clause
When I walked down the street yesterday night, I saw James.
Step 2: Next, change the verb “walk” to “walking”, and you will get:
Walking down the street last night, I saw James.
Example 2:
Since it is situated right downtown, the department store is always busy during the weekend.
👉 The subject “it” in the adverb clause refers to “the department store”. Hence, we can simplify this sentence using the participle clause.
Step 1: We first remove the subordinating conjunction “Since” and the subject “it” in the adverb clause
Since it is situated right downtown, the department store is always busy during the weekend.
Step 2: Since the word “is situated” is in the passive voice, we can remove the “is”, so the sentence will become:
is Situated right downtown, the department store is always busy during the weekend.
More examples of participle clauses:
Because I have spent all my savings on a new house, I couldn't afford to buy a new car. = Having spent all my savings on a new house, I couldn't afford to buy a new car.
After she had unpacked the suitcases, she took a shower. = Having unpacked the suitcases, she took a shower.
Sometimes, we keep the subordinating conjunctions. For example:
After we ate, we sat on the couch = After eating, we sat on the couch.
Since I came to Japan, I have met a lot of new people.= Since coming to Japan, I have met a lot of new people.
