I respectfully disagree with my colleague above - All of these examples sound perfectly natural, in fact, they sound poetic! These are examples of what I'll call "Participle/Gerund Adverbials". Basically, you're using a sentence like an adverb, to give further information about how or when the main event occurred. You could easily replace these clauses with other adverbials: Yesterday / Quickly / With a $5 bill, [he bought a ticket, walked onto the platform, and boarded the train.] In his yard / With only a hammer and saw / Last year, [he finished building the house before the rainy season set in.] Three minutes ago / In the cafe / With a heavy sigh, [he poured out a cup of coffee and looked at the woman] Languages tend to be strict about using clauses to modify things, so in order to use one rather than a different type of adverbial, like the examples above, you have to give it special grammatical equipment. You can: 1. Use a subordinating conjunction: When he arrived at the train station Because he started building the house at once After he poured out a cup of coffee 2. Make the verb into a gerund/present participle These don't necessarily imply that the action is presently going on, so for example: Past: "Coming home late Tuesday night, he made himself dinner and fell asleep" Future: "Reading the street signs, she will be able to find her way home." I hope that helps! (If you found this helpful, look me up using Find A Teacher. I'm always looking for new students!)

Because it is either happening now or in these sentences,​ it contains ING "arrivING" "startING" And "pourING"
