Form and rules
How it works
Sense linking verbs are followed by adjectives, not manner adverbs: It smells wonderful, not wonderfully.
Use look/sound/smell/taste/feel like + noun phrase: It sounds like a good idea.
Use as if/as though + clause when a full subject-verb idea follows: It looks as if it's going to rain.
Feel can describe physical/emotional state or tactile sensation depending on context.
Look at/listen to are action verbs with objects; look/sound as linking verbs describe an impression.
