Cloze / Gap-Fill in Technical Contexts
What this domain tests
A short technical passage has gaps, and you choose or supply the missing word. The passage is usually a procedure, a description of a component or an incident report. Marks are lost by choosing a word that fits the meaning but not the grammar, or the grammar but not the collocation.
Read first, fill second
Read the whole passage once for topic and purpose. Decide whether each gap needs a grammar word (article, preposition, auxiliary, pronoun, linker) or a content word (noun, verb, adjective). Then check the words immediately before and after the gap.
Grammar clues
- After a/an/the or an adjective, you usually need a noun: 'a qualified ___'.
- After a modal (must, can, should) you need the base verb: 'must ___ the supply'.
- After a preposition you need a noun or -ing form: 'before ___ the cover' (removing).
- The subject decides the verb ending: 'the bolts ___ tightened' (are).
- Singular/plural and countable/uncountable decide the article and the -s.
Collocation clues
Fixed pairs are the fastest way to the answer: carry out a test, take a measurement, apply pressure, insert a pin, remove a cover, connect a cable to a terminal, tighten a bolt with a spanner, wear PPE. If an option does not collocate, it is wrong even when the meaning seems close.
Cohesion clues
Linkers tell you the logic: however (contrast), therefore (result), then/after that (sequence), before/until (time), unless (negative condition), so that (purpose). Read the linker with the clause that follows it, not alone.
Worked example
'___ the machine has cooled down, remove the cover.' Options: Before / While / Once / Unless. Reasoning: the sentence is a safety instruction; you remove the cover after cooling, so the correct linker is 'Once'. 'Before' reverses the order and would be unsafe; 'unless' introduces a condition that does not fit.
Traps that cost marks
- A synonym that does not collocate ('do a test' instead of 'carry out a test').
- Missing a negative: unless, without, never.
- Ignoring the plural -s that the gap controls.
- Choosing the right meaning with the wrong form (noun where a verb is needed).
- Filling each gap in isolation without checking the sentence that follows.
