Mixed -ed and -ing Adjectives

In longer sentences, -ed and -ing adjectives often appear together because one part names the feeling and another part names the cause. For example: "The passengers were confused by the confusing announcement." The passengers receive the feeling, so they are confused. The announcement causes the feeling, so it is confusing.

This mixed exercise also practises common prepositions after -ed adjectives: interested in, excited about, bored with, frightened of, and disappointed with. These prepositions belong to the feeling adjective, not the cause adjective. Read the whole sentence before answering. The correct form depends on meaning, not only on the word before the blank. Ask: who feels it? and what causes it?
