1. The document discusses different types of conditional sentences and their uses. It also discusses ways to express wishes and regrets using conditionals. 2. It provides examples of rewriting sentences using different conditional structures and tenses. Various exercises are given to practice using conditional sentences correctly. 3.

OTHER WAYS OF SAYING ‘IF’
A) SUPPOSE (THAT)/SUPPOSING (THAT) = WHAT IF?
The clause which expresses the result appears in the interrogative form
Suppose he comes tomorrow, will we still meet him?
Suppose he went by train, would it be any quicker?
Supposing that he had come for an interview, would you have given him a job?
B) AS LONG AS/ SO LONG AS ; ON (THE) CONDITION THAT ; PROVIDED (THAT)/ PROVIDING (THAT).
These expressions are used to express a strong limitation. They follow the structure of the three types of conditional
sentences. They could be translated as follows ‘siempre qeu/ con tal de que / a condición de que + subjuntivo’
You can go out tonight as long as you come back by midnight.
He could have recovered provided (that) he had followed the doctor’s orders
C) IN CASE is used with the present or the past tenses to say that a condition can take place or not. IN CASE refers to actions
we can do in advance to be prepared for something
Take an umbrella in case it rains.
IN CASE OF + NOUN: ‘IF THERE IS A /AN’
In case of an accident, notify the police.
D) OTHERWISE.
A condition can be understood although it is not expressed. OTHERWISE is used in the place of a conditional clause. Its
translation could be ‘de lo contrario’.
You’d better hurry. Otherwise, you’ll be late for your appointment. (Otherwise: if you don’t hurry).

4. MIXED CONDITIONALS.
We do not always have to stick rigidly to the ‘three types of conditional sentences’. All types of conditionals can be mixed.
Any tense combination is possible if the context permits it.
If I am clever as you say I am, I would have been rich by now. (Type 1 + Type 3)
If you knew me better, you wouldn’t have said that. (Type 2 + Type 3)
If I had had your advantages, I’d be better off now. (Type 3 + Type 2)

1. If I ……………………………. (be) you, I …………………………………….. (check) my facts before I wrote that letter.
