Conditional Type 0

من طرف mohssinex2 الجمعة مايو 01, 2009 8:41 am

The conditional 0 is used to express general truths and facts (often things based on scientific fact).
Uses the simple present tense:-
Formation

(IF Clause)	(Main Clause)
If you heat water to 100°C,	it boils.

or...

(Main Clause)	(IF Clause)
Water boils	if you heat it to 100°C,

For example:

" If you drop an apple, it falls." = "An apple falls, if you drop it" (This is an absolute truth based on scientific fact - gravity).
"If you don't do your homework, I will be disappointed". = "I will be disappointed, if you don't do your homework"
(This is a general truth based on previous knowledge - you know that I am disappointed if people don't do their homework).
Note! Most zero conditional sentences mean the same thing if "when" is used instead of "if".
ex:
- people get fat if they eat junk food
- if a person practices sport,he or she always feels good
- you don't get fat if you eat healthy food
- if children don't get enough sleep at night,they get tired all day
- plants die if it doesn't rain

Use : to express statements about real o possible situations if also refers to general truths such as scientific facts ( tankhdmo C type0 f chi 7aja 7a9i9ya oula chi 7aja 3imya scientific o dma tatkon naj7a) Eg : if you put water on fire for a long time, it evoporates
