小题1:A 主旨大意题。根据文章2,3段第一句Many women find that time spent with male friends can be a liberating and somewhat refreshing break from spending time with the girls.和“Guy friends” have the potential to enrich your life in ways that female friends and boyfriends just can’t.可知这样的友谊会很有趣，故A正确。

小题3:C 细节题。根据文章第四段Traditionally, girl-guy friendships are seen as hard to maintain. Most relationships between males and females that we come across in our day-to-day lives, whether in movies or books, are romantic by nature. These cultural images make girl-guy friendships seem impossible.说明以前主要是因为男性和女性很难保持长时间的联系，除非是婚宴。而现在的情况不一样了。故C正确。
