What you'll learn
By the end of this lesson, you'll be able to join actions with present participle (-ing) clauses for a more natural, flowing style.
When do I use it?
A present participle clause (-ing) can describe an action happening at the same time as the main verb, or explain a reason:
- Same time: "Walking home, I met an old friend." (= As I was walking home...)
- Reason: "Feeling tired, she went to bed early." (= Because she felt tired...)
- Sequence of two actions by the same subject: "Opening the door, he saw the surprise." (= He opened the door and saw...)
The subject of the -ing clause must be the same as the main clause subject.
How do I form it?
-ing clause, + main clause main clause, + -ing clause
- Waiting for the bus, I checked my phone.
- Knowing the answer, he raised his hand.
- She sat by the window, reading a book.
- The children ran outside, laughing loudly.
Common mistakes for Spanish speakers
Spanish uses "gerundios" differently, so speakers either overuse the -ing ("caminando, vi a un amigo" = fine) or attach it to the wrong subject: "Walking home, the rain started" means the rain was walking! The hidden subject of the -ing clause must match the main subject. Also, do not write two full verbs with no connector: "I opened the door I saw him" needs a conjunction or a participle clause.
The -ing clause shares the main clause's subject. Same subject only.
