- well Ilaria, dont start a para with unlike...its something like u r continuing from a previous sentence and changing the para suddenly....there r some minor grammatical mistakes ...but not so much...overall its good. Just pay attention to sentence structure and how n when to change paragraph. All the best and cheers. Gud luck
Use a comma:
The table shows us the advertising expenditure in three different countries, namely Australia, South Korea, and Brazil.----Actually, I added 2 commas.
And in this case you need a comma on each side of the cause:
Unlike Brazil, which spends less money in this two sectors, the percentage of spending in these two sectors is around 15% .
Unlike Korea, where the 30% of total expenditure are divided respectively in 12% to the both sponsorship and Direct Mail sectors and only 6% to Internet, ______ (continue the sentence).
What are you saying above? Unlike Korea, what?
If I start a sentence like this, it has to continue and make it's point: Unlike Korea, where people speak Korean, ___________.
Okay, anyway I am just nitpicking. You are writing very well about a table, and that is always difficult to do!!
