FLOWS AND IDEAS
International sporting events are a prominent part for world cooperation, especially international tensions. They also describe people's patriotic feelings to support their favorite teams. Although the fact will be undeniable , I believe that these events bring a huge benefit impacts in international.
I think that it will be valued as memorized expression or I usually call it as lazy expression. Your introduction paragraph is not clear whereas you have paraphrase the essay question. Moreover, I utterly believe that you are fail to answer the question inasmuch as you the question does not ask you about benefits of disadvantages. However, the question ask you whether you agree or not with the statement.
this is an example for your introduction paragraph :
International Olympic games have changed the world through sports and given a universal dimension to the games. Such events are becoming much more popular at the moment and thus to generate a great deal of discussion. This phenomenon has been grabbing an attention of people in the world inasmuch as a global sporting event such as football world cup is appealing the growth of nationalism. Nevertheless, this situation is alarming sports experts as they assume that these spectacular events would reduce global tensions. While the argument of the sports experts is possible in particular conditions, I would argue that the global sporting competitions bring together millions of people worldwide to pay undivided attention internationally and locally as a sense of patriotism arises out of the concerns of world citizens.KEEP SPIRIT, KEEP STUDY. ;)
