Examples
"The successful implementation of the new system saved time."
The blank is the subject, modified by an adjective, so a noun ('implementation') is needed.
"The CEO spoke very confidently about the company's future."
The blank modifies the verb 'spoke', so an adverb ('confidently') is required.
"It is important to maintain a productive work environment."
The blank modifies the noun 'environment', so an adjective ('productive') is needed.
What TOEIC specifically tests
- Choosing an adjective when an adverb is needed to modify a verb.
- Choosing a verb when a noun is needed as the subject or object.
- Words with similar endings that are different parts of speech (e.g., 'arrival' is a noun, not an adjective).
Common questions
How can I quickly identify the part of speech needed?
Look at the words immediately before and after the blank. Articles (a/an/the) and prepositions (of/in/at) signal a coming noun. A blank before a noun needs an adjective. A blank after a verb often needs an adverb.
Are all words ending in -ly adverbs?
Most are, but there are exceptions. 'Friendly', 'costly', and 'timely' are adjectives.
