示范答案：
Personally speaking, I will say that having friends from different cultures is of significant importance based upon several reasons. To begin with, friends from different culture backgrounds tend to approach issues from different ways in that we grow up in different social contexts and hence share different sets of education, world view and mode of thinking, and the endeavour of understanding that difference will surely turn out to be rewarding and beneficial. Secondly, it also makes good sense if we can have a chance to practice a different language and understand a different culture via socialising with friends from different cultures, I mean, why not? It definitely will prove to be a win-win situation!
