Using English Conditionals
Using English Conditionals
Open with the idea that conditionals are not just forms to memorise: they express different relationships between condition and result, especially real versus unreal meaning.
Learning goal
I can recognise, explain and accurately use the zero, first, second and third conditionals in context, including their meaning, structure and typical use.

The four main conditionals
Zero conditional: general truths and cause-and-effect facts
First conditional: likely future possibilities
Second conditional: unreal or hypothetical present/future situations
Third conditional: unreal past situations and regrets
The key contrast is real conditions versus unreal conditions
This slide frames the whole system before going form by form. Keep the labels consistent across the lesson.
Which pair usually expresses real conditions?
Zero and first
First and third
Second and third
Zero and third
Checks the core contrast from slides 2 to 4: zero and first are usually real; second and third are usually unreal.
Real and unreal meaning
Conditionals do not only show time; they also show how the speaker sees the situation.
Real conditions: presented as facts, routines or genuine possibilities
Unreal conditions: presented as imaginary, unlikely or impossible
Zero and first conditionals are usually real
Second and third conditionals are usually unreal
At C1 level, stress that verb tense does not always match time directly. For example, past forms in the second conditional signal distance or unreality, not necessarily past time.
What does the teacher think?
The teacher asks a female student:
What will you do if you are pregnant?
The teacher simply asks a hypothetical question.
The teacher thinks the student is pregnant and asks about possible future plans.
The teacher knows the student is pregnant and asks about her future plans.
The teacher asks what someone needs to do in general when they are pregnant.

Clause pattern and punctuation
Basic pattern: if-clause + main clause
If it rains, I will go to school by bus.
The order can change: main clause + if-clause
I will go to school by bus, if it rains.
Use a comma after the if-clause when it comes first
The meaning stays the same, but emphasis may shift
You can briefly mention alternatives such as unless, provided that or as long as only if helpful, but keep the focus on standard if-clause patterns.
Zero conditional structure
Standard pattern: if + present simple, present simple
Both clauses usually use the present simple
Other present forms may appear if the meaning stays general, but the core pattern is stable
Example pattern: If + cause, result happens
Keep the emphasis on the standard school pattern, while acknowledging that authentic English can vary slightly in tense choice when still expressing general validity.
Which sentence is a zero conditional?
If you heat ice, it melts.
If you heat ice, it will melt.
If you heated ice, it would melt.
If you had heated ice, it would have melted.
The distractors mirror the other three conditional forms so students must identify meaning and structure together.

First conditional structure
Standard pattern: if + present simple, will + base verb
The if-clause refers to the future, but English uses a present form there
The main clause uses will
Example: If it rains, we will stay inside.
Students often overuse will in the if-clause. Correct the pattern explicitly: not if it will rain in the standard first conditional.

Which sentence shows a first conditional?
If people eat too much sugar, they gain weight.
If you eat too much sugar tonight, you will feel ill.
If you ate too much sugar tonight, you would feel ill.
If you had eaten too much sugar, you would have felt ill.
Targets the zero-versus-first contrast from slide 11: general pattern versus specific future possibility.
Why is one zero and the other first conditional?
Expected elements: zero conditional = what generally happens; first conditional = what may happen in a specific future case. Strong answers may mention general truth versus realistic future possibility.
Second conditional structure
Standard pattern: if + past simple, would + base verb
The past simple here marks unreality or distance, not past time
Standard formal usage often prefers were with all subjects in very unreal situations
Example: If I were you, I would wait.
At C1, note that both was and were may occur in real usage, but were remains the standard form in formal teaching, especially in fixed expressions such as If I were you.

Third conditional structure
Standard pattern: if + past perfect, would have + past participle
The if-clause shows the unreal past condition
The main clause shows the imagined past result
Example: If they had left earlier, they would have caught the train.
Students often confuse past perfect with present perfect here. Keep the form contrast visible.

Choosing the right conditional
Ask Is it general, likely, hypothetical or impossible because it is past?
Then choose the form that matches that meaning
General truth → zero conditional
Likely future → first conditional
Hypothetical present/future → second conditional
Unreal past → third conditional
This slide resolves the central question of how meaning drives form choice.
Zero conditional meaning
Used for general truths, scientific facts and regular cause-and-effect
The result is presented as something that normally or always happens
It does not usually refer to one specific future event
It often sounds objective and factual
Useful examples: If you heat ice, it melts. If people do not sleep enough, they become less focused.
First conditional meaning
Used for a real and possible future condition
The speaker sees the condition as realistic or likely enough to consider seriously
It often expresses plans, warnings, promises or predictions
The result depends on whether the condition is met
Contrast with the zero conditional: the first conditional refers to a specific future possibility, not a general truth.
Zero or first conditional?
Zero conditional: what generally happens
First conditional: what may happen in a specific future case
If people eat too much sugar, they gain weight. → general pattern
If you eat too much sugar tonight, you will feel ill. → specific future possibility
This contrast is crucial because learners often choose between these two based on time alone instead of general versus specific meaning.
Which sentence sounds more hypothetical or unlikely?
If I get the job, I will move.
If I got the job, I would move.
If I had got the job, I would have moved.
If I get the job, I move.
Checks speaker attitude in the first-versus-second contrast: the second conditional creates distance from reality.
Second conditional meaning
Used for unreal, imaginary or unlikely present/future situations
The speaker presents the condition as distant from reality
It is common for hypotheses, advice and imagined alternatives
It can sound more tentative or more speculative than the first conditional
Make the semantic contrast explicit: first conditional = possible future; second conditional = hypothetical or unlikely present/future.
First or second conditional?
First conditional: the speaker sees the condition as genuinely possible
Second conditional: the speaker sees it as hypothetical or unlikely
If I get the job, I will move. → realistic future option
If I got the job, I would move. → more distant or less likely
This is a useful place to emphasise speaker attitude. The grammar choice reflects judgement about reality, not just chronology.
How does the speaker's attitude change here?
Expected elements: If I get the job, I will move = realistic future option; If I got the job, I would move = more distant, less likely, more hypothetical. Students should refer to speaker viewpoint, not only tense names.
Which form matches an unreal past condition?
if + present, will + verb
if + past, would + verb
if + past perfect, would have + participle
if + present, present
Tests recognition of the third conditional structure after slides 16 to 21.
Third conditional meaning
Used for unreal past situations
The speaker imagines a different past and its different result
It often expresses regret, criticism, relief or retrospective analysis
The condition could not be fulfilled because the past is finished
Stress that this is not about a possible change now; it is about a past condition that did not happen.
Second or third conditional?
Second conditional: unreal present or future
Third conditional: unreal past
If I were richer, I would travel more. → present/future imagination
If I had been richer, I would have travelled more. → past imagination
Students often notice the similar meaning but miss the time reference. Keep time and reality both visible.
What is one clue you use to choose a conditional?
Expected elements: students should justify a choice using meaning categories from slide 21: general, likely, hypothetical, or impossible because it is past. They may mention time reference and degree of reality.
What helped you understand these forms best?
Reflection prompt with no single correct answer. Encourage concrete comments: examples, contrasts, patterns, or teacher explanations that helped.
Which conditional still feels hardest to use?
Reflection prompt with no single correct answer. Useful for diagnosing whether students still confuse time, structure or speaker attitude.
