conditional sentences
TRANSCRIPT
What is conditional sentence?1. Conditional sentence is a complex sentence, which consists
of an if clause.
2. The if clause is the dependent clause used to express a condition for result (independent clause).
For instance :
condition resultIf interest rates rise company profits will fall.
There are four type of conditional sentences:
1.Zero type (real condition)2.First type (future/ real possible condition)3.Second type (Present unreal condition)4.Third type (Past unreal condition)
The four types of conditional sentences
1. Zero conditional (Real condition)
condition result
If clause (dependent)If + present tense,
Independent clause+ present tense
Example:If students study systematically,
They usually get good grades
1. ZERO CONDITIONAL•If + present simple, + present simple
•Meaning: the condition indicates facts or things are always true; the time is not specific; if has the same meaning as when or whenever,
Zero Conditional Examples:

2. First conditional (future possible con)
If clause (dependent)condition

They will be eligible for an exemption
• 2. FIRST CONDITIONAL• If + present simple, + future tense with
will or modal verbs may/can/might/should + infinitive
• Meaning: expresses a possible condition in the future with a reasonably likely result.
• If the students score at least 85% on the exam, they will be eligible for an exemption.
3. Second conditional ( Present unreal)
If clause (dependent) Condition
Independent clauseResult

the exam in February.
2. Second conditional (Present Unreal)•If + simple past, + would/might/could + infinitive •Meaning: refers to imaginary, hypothetical situations; talking about a possible event in the future, but results are only remotely likely to happen; often used to give advice.•Example:•If I knew the student well, I would advise him not to take the exam in February.
Example Explanation
If I were you, I would drive more carefully in the rain.
I am not you — this is unreal.
Paula would be sad if Jan left.
Jan will not leave — that's not going to happen.
If dogs had wings, they would be able to fly.
Dogs don't have wings — that's impossible.
4.Third conditional (Past Unreal)
If clause (dependent) Condition
Independent clauseResult
If + past perfect, + would/might/could + infinitive could have + past participle
Example :If the students had studied harder,
They could have passed the final exam.
4. THIRD CONDITIONALIf + past perfect, + would/could/might + have + past participle •Meaning: refers to an imaginary past situation and speculates what might have been;
•It is impossible that the condition will be fulfilled because it refers to the past.
• If I had worked harder I would have passed the exam(but I didn't work hard, and I didn't pass the exam).
• If I'd known you were coming I'd have baked a cake(but I didn't know, and I haven't baked a cake).
• If Paul Walker hadn’t joined in his friend’s car, he would have not died in the accident.
(but He joined in his friend’s car, and he didn’t survive in the accident)
The Conditional Clause using “Unless”
1. Unless has the same meaning as “if ….. Not” Eg: I won’t go if you don’t come with me.
I won’t go unless you come with me.2. We often use “unless” in sentences which warn the result
of doing somethingEg : If you don’t hurry, you’ll be late.
Unless you hurry, you’ll be late.3. Note that “unless’ is followed by an affirmative verb,
I won’t go unless you come with me.Unless you hurry, you’ll be late.
4. Also note that the main clause is usually in the simple present tense.
Eg : He can’t see clearly unless he wears his spectacles.
