Subject-Verb Agreement Rules:

1. Number: Singular subject → singular verb; plural subject → plural verb

   • The doctor is here. (singular)
   • The doctors are here. (plural)

2. Compound Subjects:

   • With and: usually plural — “Tom and Jerry are friends”
   • With or/nor: verb agrees with closer subject — “Neither the doctor nor the nurses are” (wait — nurses is plural)

3. Collective Nouns: US English treats as singular (team is); British English may treat as plural

   • The jury has reached its verdict. (US)
   • The team are playing well. (UK, informal)

   • Singular: anyone, everyone, someone, nobody, each, either, neither, one
   • Plural: both, few, many, several, others
   • Either singular or plural: all, any, more, most, none, some
   • Everyone is responsible. (singular)
   • Few are present. (plural)

5. Relative Clauses:

   • The doctor who is here is competent. (defining — singular)
   • The doctors who are here are competent. (defining — plural)
   • The doctor, who is competent, works here. (non-defining — always singular)

Prepositions (Common Collocations in Medical/Academic English):

Preposition	Usage	Example
at	Exact point in time, small places	at 9 o’clock, at the station
in	Enclosed spaces, years, months	in the room, in 2020, in January
on	Surfaces, days, dates	on the table, on Monday, on 14 August

to	Direction, until, compared with	to Lahore, 9 to 5, similar to
from	Origin, separation, prevention	from Pakistan, absent from, prevent from

Conjunctions:

Type	Conjunction	Use
Coordinating (equal)	and, but, or, nor, for, yet, so	Join independent clauses
Correlative	both…and, either…or, neither…nor, not only…but also	Paired conjunctions
Subordinating	because, although, if, when, while, after, before, since, unless	Join dependent + independent clause

Active vs Passive Voice:

When to use Passive	Example
Agent is unknown	The patient was examined.
Agent is unimportant	Mistakes were made.
To emphasise receiver	The patient was given priority treatment.
Scientific/Medical writing	The solution was heated to 37°C.

⚡ Common mistakes: Using “different from/to/than” inconsistently — MDCAT prefers “different from.” Confusing “few” (negative — almost none) with “a few” (positive — some). Confusing “much” (uncountable) with “many” (countable plural). Using “which” for persons — use “who” for people, “that” for both people and things.

Grammar Usage — Advanced Notes

Direct and Reported Speech:

Rules for Backshift (Tense Shift):

Direct Speech	Reported Speech
Present Simple → Past Simple	”I am sick” → He said he was sick
Present Continuous → Past Continuous	”I am studying” → He said he was studying
Present Perfect → Past Perfect	”I have finished” → He said he had finished
Past Simple → Past Perfect	”I studied” → He said he had studied
will → would	”I will come” → He said he would come
can → could	”I can help” → He said he could help
must → had to (obligation)	“I must go” → He said he had to go

Note: Universal truths and past facts do NOT change: “The Earth revolves around the Sun.” → He said the Earth revolves around the Sun.

Question Tags: Forming tags: If statement is positive → negative tag; if statement is negative → positive tag:

• She is a doctor**, isn’t she?** (positive statement → negative tag)
• He can’t swim**, can he?** (negative statement → positive tag)
• They were there**, weren’t they?** (positive → negative)
• This isn’t right**, is it?** (negative → positive)

Imperative tags: “Open the door**, will you?” / “Don’t go, will you?**”

Negatives:

• Double negatives are incorrect in Standard English: ✗ I don’t have no money → ✓ I don’t have any money / ✓ I have no money
• Hardly, barely, scarcely, rarely, seldom, only — already negative: ✗ I can’t hardly → ✓ I can hardly

Relative Clauses:

Type	Punctuation	Restrictive?	Which/Who
Defining (restrictive)	No commas	Essential to meaning	That (preferred for things) / Who
Non-defining	Commas	Extra information	Which (for things) / Who

• The doctor who saved my life is here. (defining — which doctor?)
• Dr. Khan, who saved my life, is here. (non-defining — additional info)
• The book that you lent me was excellent. (defining)
• His car**, which was new,** broke down. (non-defining)

Cleft Sentences: For emphasis, restructure sentences:

• Simple: I saw him at the hospital.
• Cleft: It was at the hospital that I saw him.
• Simple: She told me to rest.
• Cleft: It was the doctor who told me to rest. / It was rest that the doctor told me to do.

Inversions: Normally subject comes before verb. Inversion reverses this in certain constructions:

• Question form: Have you seen it? (auxiliary before subject)
• Negative adverb at beginning: Never have I seen such a thing. (negative word triggers inversion)
• Only + phrase at beginning: Only then did I understand.
• So…that: So angry was he that he left.
• If clauses (conditional inversion): Were I you, I would study harder. (instead of If I were you)

Homophones (Frequently Confused Words):

Word Pair	Distinction
Your/You’re	Your = possessive; You’re = you are
Their/There/They’re	Their = possessive; There = place; They’re = they are
Its/It’s	Its = possessive; It’s = it is or it has
Affect/Effect	Affect = verb (to influence); Effect = noun (result); Effect can be verb (to bring about)
Than/Then	Than = comparison; Then = time sequence
These/See	These = plural of this; See = verb

Lead/ Led	Lead (pronounced “leed”) = present verb; Led (pronounced “led”) = past of lead
