PARTICIPLES.
A participle is a verb that acts like an adjective. They can also have their own phrases. Examples:
1/
He burst into the room.
This is the same sentence with a PARTICIPLE PHRASE added:
Shouting in fury, he burst into the room.
Kicking the door into splinters, he burst into the room.
He burst into the room, terrifying the butler.
2/
b) It allows you to describe two things happening at once, which is awesome.
3/
a) Some students will listen to your explanation, watch your modelling, and still begin their sentence with an adverb. They were drilled on adverbs in Primary, and showing them another way takes time.
4/
Incorrect example:
"Looking through my binoculars, a strange shape moved inside the house."
This is wrong because the subject (strange shape) isn't the one with binoculars.
5/
"Towering above me, I saw the snow-capped mountains."
This is pretty clear and makes sense, but because "towering" doesn't attach to the subject ("I") it leads you down a problematic path and should probably be corrected.
6/
Listening to the radio, and pondering the impact of the day's news, I realised I'd made a terrible mistake.
