1.5 Sentence Completion: Choosing the Best Word

Sentence Completion: Choosing the Best Word

The official Kent Test familiarisation booklet shows three kinds of English question: comprehension on a passage, spotting the mistake in a sentence, and choosing the best word or group of words to complete a sentence. The third type is the one children most often lose easy marks on, because it looks trivial and is not.

The wording of the official instruction is worth memorising: choose the answer that makes the sentence make sense and is written in correct English. Two tests, not one. A word can pass the grammar test and still be wrong.

The Official Example, and Why It Is Harder Than It Looks

The booklet's worked example is:

The letter was stained and crumpled but in the bright moonlight I could still ____ almost every word.

A reed B wrote C red D read E write

The answer is read. The booklet's own explanation is the whole lesson:

• reed, red and wrote fail on grammar or sense.
• write is grammatically correct — "I could still write almost every word" is a legal English sentence — but it does not make as much sense in the sentence as a whole, because the sentence is about a letter that is stained and crumpled and being looked at by moonlight.

So the trap is deliberate: at least one distractor will be grammatical. Children who stop at "does this sound right?" pick it.

The practice item works the same way:

Johnny jumped ____ a muddy puddle and splashed my new coat.

A under B over C across D on E in

Four of the five prepositions fit "Johnny jumped ___ a muddy puddle" perfectly well. Only in survives the second half of the sentence: if he jumped over or across the puddle, nothing splashes.

The Four Distractor Families

The Read-To-The-End Method

Because two distractor families are only exposed by the end of the sentence, the method must force the child to read that far.

1. Read the whole sentence once, saying "blank" at the gap. Do not look at the options yet. Looking early anchors the child to whichever option their eye lands on.
2. Predict. Say what kind of word is needed — a movement word, a joining word, a past-tense verb. A prediction made before seeing the options is not contaminated by them.
3. Substitute each option in the complete sentence, right to the full stop. Five substitutions take about fifteen seconds and eliminate the half-sentence trap entirely.
4. Reject on evidence, not on feel. For each rejected option, be able to name the reason: wrong tense, wrong preposition, contradicts the second clause, homophone.
5. Choose the survivor. If two survive, prefer the one that is more specific to the situation described — that is what "makes the best sense in the sentence as a whole" means.

Grammar Points That Sentence-Completion Items Lean On

Sentence completion is where the paper quietly tests grammar knowledge without labelling it as grammar.

• Subject–verb agreement: The box of old photographs ____ on the shelf → was, not were. The subject is box, not photographs.
• Tense consistency: By the time we arrived, the train had already ____ → left, not leave or leaving.
• Prepositions fixed by the verb: you depend on, arrive at, differ from, consist of. These cannot be worked out logically; they have to be known.
• Comparatives: of the two routes, the coastal one was the ____ → shorter, not shortest. Two things take the comparative; three or more take the superlative.
• Double negatives: He did not have ____ money left → any, not no.
• Conjunction logic: She was exhausted, ____ she finished the race → but or yet, not because. The joining word has to match the relationship between the halves.

Group-of-Words Options

The instruction says "word, or group of words", so some items replace the gap with a whole phrase:

____ , the museum closed early and we never saw the fossils.

A Because of the storm warning B The storm warning C Storm warning was D Despite the storm warning E Storming warning

Here A works: it is a complete adverbial opener with a comma, and it explains the closure. D is grammatical but reverses the logic — despite would mean the museum stayed open. This is the "grammatical but senseless" family again, dressed up as a phrase.

Practice Discipline

Work these in batches of ten with a timer, and mark them in a specific way: for every item the child gets wrong, they must write the reason the wrong option was tempting. After thirty or so items, the same three or four reasons will keep reappearing, and those are the child's real weaknesses rather than "sentence completion" in general.
