Lesson 26
Comparisons and Relative-Clause Agreement: Intensifiers, Prefer and 'One of Those Who'
This lesson groups five rules that students commonly confuse because they look similar on the surface. Identify how many things are compared and whether the comparison is equal, higher or lower. Work through the examples slowly once; speed comes after the pattern is clear.
What you will learn
- Understand and apply: 'The + comparative, the + comparative' shows linked change.
- Understand and apply: 'One of the + superlative' is followed by a plural noun.
- Understand and apply: Use 'much/far/a lot' to intensify comparatives.
- Understand and apply: 'One of those who ...' normally takes a plural verb inside the relative clause.
- Understand and apply: Use 'prefer X to Y'.
For every rule: spot the trigger → identify the grammatical relationship → apply the form → check meaning.
Before you start
Try the warm-up without checking the rule. The purpose is to expose the instinct you currently use, not to score marks.
Which sentence follows the target grammar pattern?
A. The more you review, the faster you recognise recurring errors.
B. More you review, faster you recognise recurring errors.
Answer: A. Use paired comparatives to show that one change varies with another.
Rule 1 · G126
'The + comparative, the + comparative' shows linked change
Use paired comparatives to show that one change varies with another.
Correct example
The more you review, the faster you recognise recurring errors.
Incorrect example
More you review, faster you recognise recurring errors.
Interpretation
Use paired comparatives to show that one change varies with another. In a test, do not memorise this as an isolated sentence. Identify how many things are compared and whether the comparison is equal, higher or lower. The correct example shows the pattern in context; compare it directly with the incorrect version and identify the exact word that must change.
Why it matters
Comparison questions reward structural checking: degree, number of items and parallel objects must all line up.
Common exam trap
Mixing two comparison patterns, such as 'more easier' or 'prefer X than Y'.
How to spot it
Count the items being compared and scan for comparison markers such as than, as...as, most, one of and to.
3-step solving method
- Identify the comparison set.
- Choose comparative/superlative/equality pattern.
- Check that the two compared items are logically parallel.
Why the incorrect example fails
The target structure requires this rule: Use paired comparatives to show that one change varies with another. In the incorrect version, the repair is to replace “More” with “The more”; add “the”. That is the exact edit a student should be able to justify in an error-spotting question.
Nuance and memory hook
A grammatically correct comparison must also compare logically comparable things.
Two → comparative; group → superlative.
Quick check
Without relying on what 'sounds right', explain which part of this sentence violates the rule: “More you review, faster you recognise recurring errors.”

Rule 2 · G127
'One of the + superlative' is followed by a plural noun
After one of the best/most/etc., the noun naming the group is plural.
Correct example
It is one of the most useful chapters in the book.
Incorrect example
It is one of the most useful chapter in the book.
Interpretation
After one of the best/most/etc., the noun naming the group is plural. In a test, do not memorise this as an isolated sentence. Identify how many things are compared and whether the comparison is equal, higher or lower.

A grammatically correct comparison must also compare logically comparable things.
BY = deadline; UNTIL = continuation.

Rule 3 · G128
Use 'much/far/a lot' to intensify comparatives
Use degree modifiers such as much, far, a lot, slightly or a little before a comparative.
Correct example
This approach is much more efficient.
Incorrect example
This approach is very more efficient.
Interpretation
Use degree modifiers such as much, far, a lot, slightly or a little before a comparative. In a test, do not memorise this as an isolated sentence. Identify how many things are compared and whether the comparison is equal, higher or lower. The correct example shows the pattern in context; compare it directly with the incorrect version and identify the exact word that must change.

Rule 4 · G129
'One of those who ...' normally takes a plural verb inside the relative clause
In a structure such as 'one of the students who ...', who refers to the plural noun students, so the verb inside the relative clause is normally plural. With 'the only one who ...', the relative-clause verb is singular.
Correct example
She is one of the students who work consistently.
Incorrect example
She is one of the students who works consistently.
Interpretation
In a structure such as 'one of the students who ...', who refers to the plural noun students, so the verb inside the relative clause is normally plural. With 'the only one who ...', the relative-clause verb is singular. In a test, do not memorise this as an isolated sentence. Decide what noun the clause describes and whether the information is essential. The correct example shows the pattern in context; compare it directly with the incorrect version and identify the exact word that must change.
Why it matters
Relative clauses combine reference, agreement and punctuation, so one small error can change meaning.
Common exam trap
Looking only at the noun before the clause and forgetting the relative pronoun's role inside its own clause.
How to spot it
Box the finite verb, then ask which noun actually controls it. Ignore nearby nouns that belong inside phrases.
3-step solving method
- Find the antecedent.
- Decide whether the clause is defining or extra.
- Check the relative word's role and punctuation.
Why the incorrect example fails
The target structure requires this rule: In a structure such as 'one of the students who ...', who refers to the plural noun students, so the verb inside the relative clause is normally plural. With 'the only one who ...', the relative-clause verb is singular. In the incorrect version, the repair is to replace “works” with “work”. That is the exact edit a student should be able to justify in an error-spotting question.
Nuance and memory hook
Punctuation can change the meaning of a relative clause, not merely its rhythm.

Rule 5 · G130
Use 'prefer X to Y'
The verb prefer normally takes to, not than, when directly comparing two nouns or gerunds.
Correct example
I prefer reading editorials to memorising word lists.
Incorrect example
I prefer reading editorials than memorising word lists.
Interpretation
The verb prefer normally takes to, not than, when directly comparing two nouns or gerunds. In a test, do not memorise this as an isolated sentence.
