This document discusses conditional sentences with "if" clauses. It defines conditional sentences as sentences that express an action in the main clause can only occur if a certain condition in the "if" clause is fulfilled. There are three types of conditional sentences: type 1 uses "if + present" and "will + infinitive"; type 2 uses "if + past" and "would + infinitive"; type 3 uses "if + past perfect" and "would + have + past participle". The document provides examples and explanations of each type and their meanings in referring to possible future, unlikely present, or impossible past situations. It concludes with an exercise matching conditional sentences to their types.
2. Definition of Conditional
Sentences
1. Conditional Sentences are also known as Conditional
Clauses or If Clauses. They are used to express that the
action in the main clause (without if) can only take
place if a certain condition (in the clause with if) is
fulfilled.

3. Types of Conditional Sentences
Type 1
➔
It is possible and also very likely that the condition will be fulfilled.
➔
if + Simple Present, will-Future
➔ if he arrives, i will smack him
➔ Fact : he never come
Type 2
➔
It is possible but very unlikely, that the condition will be fulfilled.
➔ If + Simple Past, Conditional I (= would + Infinitive)
➔ If I found the President’s wallet, i would bring back to him
➔ Fact : I never found the President’s wallet
Type 3
➔
It is impossible that the condition will be fulfilled because it refers to the past.
➔ if + Past Perfect, Conditional II (= would + have + Past Participle)
➔ if I had the money, i would have married with my fiance
➔ Fact : i never had the money
4. Function of Each Type
Type 1
★ Conditional Sentences Type I refer to the future. An action in the future will only happen if a
certain condition is fulfilled by that time. We don't know for sure whether the condition actually
will be fulfilled or not, but the conditions seems rather realistic.
Type 2
★ Conditional Sentences Type II refer to situations in the present. An action could happen if the
present situation were different.
Type 3
★ Conditional Sentences Type III refer to situations in the past. An action could have happened in
the past if a certain condition had been fulfilled. Things were different then, however. We just
imagine, what would have happened if the situation had been fulfilled.
