Passage One
Questions are based on the following passage.
Research on friendship has established a number of facts, some interesting, even useful.Did you knowthat the average student has 5 to 6 friends, or that a friend who was previously an enemy is liked more thanone who has always been on the right side? Would you believe that physically attractive individuals arepreferred as friends to those less comely, and is it fair that physically attractive defendants are less likely to befound guilty in court? Unfortunately, such titbits (趣闻,轶闻 ) don't tell us much more about the nature orthe purpose of friendship.
In fact, studies of friendship seem to implicate more complex factors.For example, one functionfriendship seems to fulfill is that supports the image we have of ourselves, and confirms the value of theattitudes we hold.Certainly we appear to project ourselves onto our friends; several studies have shown thatwe judge them to be more like us than they objectively are.This suggests that we ought to choose friendswho are similar to us rather than those who would be complementary.In our experiment, some developingfriendships were monitored amongst first year students living in the same hostel.It was found that similarityof attitudes (towards politics, religion and ethics, pastimes and aesthetics) was a good predictor of whatfriendships would be established by the end of four months, though it has less to do with initial alliances--not surprisingly, since attitudes may not be obvious on first inspection.
There have also been studies of pairings, both voluntary (married couples) and forced (studentroommates), to see which remained together and which split up.Again, the evidence seems to favorsimilarity rather than complementarity as an omen of successful relationship, though there is a complication:where marriage is concerned, once the field is narrowed down to potential mates who come from similarbackgrounds and share a broad range of attitudes and values, a degree of complementarity seems to becomedesirable.When a couple are not just similar but almost identical, something else seems to be needed.Similarity can breed contempt; it has also been found that when we find others obnoxious, we dislike themmore if they are like us than when they are dissimilar.
The difficulty of linking friendship with similarity of personality probably reflects the complexity ofour personalities: we have many facets and therefore require a disparate group of friends to support us.Thisof course can explain why we may have two close friends who have little in common and indeed dislikeeach other.By and large, though, it looks as though we would do well to choose friends (and spouses) whoresemble us.If this were not so, computer dating agencies would have gone out of business years ago.
