A little imagination goes a long way in this hilarious debut children’s book by Christopher E. Bell. When the Bobby siblings hear a knock at the door, it could be anyone (or anything) on the other side! Perfect for kids with wild imaginations, with clever, innovative illustrations by Oliver Bundoc. A fun bit of silliness for the beginning reader, a toddler at bedtime, or anyone who enjoys letting a simple idea spiral out of control for a little while.
Your kids will be asking to read this story again and again.The main grammatical issue is whether the past participle ‘opened’ can be used as an adjective in the same way that other past participles are commonly used,
e.g. “The door is closed,” “The streets are all plowed,” and “Her toy is broken.” As a rule, no. We use the adjective ‘open.’ The past participle ‘opened’ will normally be found only in passive voice constructions, e.g. “The door is opened by electronic sensors and motors.”
Now, ‘unopened’ is common enough, e.g. “The package is still unopened,” and there are a few cases where ‘opened’ might be used in particular circumstances, e.g.
“An opened letter lay on the table.” This is because an ‘open letter’ is something else, a letter whose contents have been published openly.
