Below method are very useful in ielts speaking, part third. ( I share my experience in near future, why?).  It helps when you can not show clear position to listener and try to give balance standing points.

Method 1

*It depends.

*If,

*But if, 

It depends. If the food is/were expensive because the restaurant has/had a famous chef, then the food would probably be better. But if the food is expensive because it's in a cool part of town, or because they want to be seen as high quality, then it's probably not worth the money. 


Method 2

-Cause and effects 

They definitely should. If kids learn to eat healthily from a young age, they will have better eating habits as they get older. If they have good eating habits, they'll perform better in school, and this will hopefully lead to more opportunities for them in the future. 


Method 3

*Reversal/ showing contrast  

*If we/they do not 


Method 4

Conditional rules 

If you visited there, you would have met her.
