Vocabulary and Word Usage
The Vocabulary and Word Usage domain tests whether you can choose the word a native-like sentence actually requires, not merely one with roughly the right meaning. Items appear as sentence completion, synonym discrimination, collocation, and word-formation tasks, and the distractors are usually near-misses rather than obvious errors.
Meaning is not enough
Every item tests three layers at once: denotation (the dictionary sense), connotation (positive, negative, neutral), and grammatical behaviour (whether the word is transitive, countable, or followed by a particular preposition). A word that passes the meaning test can still fail the other two.
- affect (verb) vs effect (noun; as a verb, "to bring about": effect change)
- economic (relating to the economy) vs economical (money-saving)
- historic (momentous) vs historical (relating to history)
- considerable (large) vs considerate (thoughtful)
- sensible (reasonable) vs sensitive (easily affected)
Collocation decides many items
English selects partners somewhat arbitrarily, so learn chunks rather than isolated words: make a decision, do research, raise a question, rise sharply, heavy rain, highly unlikely, strongly influenced. A grammatically possible but non-collocating word (strong rain) is marked wrong.
Word formation
Recognise the productive affixes: negation (in-, im-, il-, ir-, un-, dis-, mis-), noun-forming (-ment, -ity, -ance, -ness), adjective-forming (-ive, -ous, -able, -ful). Decide which word class the gap needs before choosing a form: His argument was surprisingly ___ requires an adjective, so convince must become convincing, not convinced.
Worked example
The new regulations will ___ the daily lives of thousands of families. Options: affect / effect / influence / impact. The gap needs a transitive verb. Effect as a verb means "bring about" and does not take lives as its object. Impact is chiefly intransitive with on in careful usage. Influence is possible but implies shaping opinions or decisions rather than directly altering conditions. Affect is the standard verb for producing an effect on something. Answer: affect.
Traps that cost marks
- -ed/-ing adjectives: I am bored vs the film is boring.
- Uncountables: information, advice, equipment, research, evidence take no plural -s and no a/an.
- First-language interference in collocation: learn knowledge → acquire/gain knowledge; open the light → turn on the light.
- Choosing from the Chinese sense of a word instead of its English range.
