a or an
We have touched on this already this week. Use "a" if the following word begins with a vowel (apart from "h").
Use "an" if the following word begins with a vowel or "h".
If you are still unsure, read it aloud using "a" and "an" and one will sound right.
This is a verb that is in the past tense but progressive means it sounds like it is still going on. There is an example on the page but here are a few more examples:
We were playing very nicely.
He was enjoying learning a new skill.
They were signing in the shower.
Prepositions again... this should be fun!
Example: The fully white dog was sat between its friends.
