. i like to know your oppinion about structre and grammer and suitable using of words
I understand you are preparing for a speaking task.
Generally this is the structure I used to follow;
Express my choice - I think cleaning up the city is the most important job.
Tell my first reason why I choose that option; The first reason why I think it is important is that cleanliness is the most important thing to keep good hygienic conditions.
Tell one example to support this reason; Suppose the garbage in the city is not collected properly. The whole city would be in a mess and people would soon fall sick.
If you have time, tell them a second reason
2nd reason; Also, if we dont keep our city clean, it would affect the local tourism very badly.
Example; because the tourist would be scared of touring in highly polluted cities.
:) that's the structure, I recommend for you too :)
