S V
- Without IF : - Had he met you, he would have talked to you.
first V S
. We can use IF with many different structures. Here are the most common:
1.1. Open present or future conditionals :
IF + present simple + will + infinitive
- If he asks me, I’ll help him. ( Perhaps he will ask me)
VI. CONDITIONAL SENTENCES
1.2. Unreal present or future conditionals:

IF + past simple + would + infinitive
- If he asked me I would help him ( But he won’t ask me, or he
probably won’t )
1.3. Unreal past conditionals
IF + past perfect + would have + past participle
- If he had asked me I would have helped him
( But he didn’t ask me )
1.4. General conditionals:
IF + present simple + present simple
- If he asks me, I always help him. ( = Whenever he asks me … )
- If we heat metal, it expands.
The Passive is formed by BE + ED (past participle).
In a passive sentence the object of an active verb
becomes the subject of the passive sentence.
Active : - Columbus discovered America.
Passive : - America was discovered by Columbus.
N.B. Only transitive verbs (that is, verbs that take an object) are used in
the passive.
+ The passive is used when it is more convenient or important to stress the
thing done than who performed it, or when the person who did the action is
not known.
Active: - The thief stole my wallet.
Passive : - My wallet was stolen. (more usual)
