***** NOT A TEACHER *****
As you know, I am no writer, but I humbly suggest that the first two sentences are repetitive.
Do you think that these two sentences are "good" writing: I love television because it is interesting. Television is interesting because
it has good shows. (I am sure that you yelled, "No way!")
I think that writing teachers tell us to get to the point in the first sentence. You say that marketing is your major. So I think that
your first sentences should be combined into one sentence, something such as:
Marketing is my major, so I prefer to study abroad, where I can get a better sense of globalization. Such hands-on experience
will help me to make more effective decisions for my company when I return home. The United States, for example, has
renown professors of marketing, of whom many have developed very insightful theories. I am eager to attend their lectures.
"Hands-on experience" is -- currently -- a very popular term here in the States. It means to have practical experience -- not
just book studies in a classroom. For example, there is a very important world leader (no name, of course) who claims that he
can speak French. But when some French reporters spoke to him in that beautiful language, he could not understand their
questions. In other words, he knows French in theory. In reality, he does not.
