阅读理解 It is often said that you can't have too many friends. But it seems that there is a natural limit to the number of people we stay in touch with. A study found that when we make new friends, by starting a new job or going to university, we downgrade or even drop old ones. And while the friends may change, the number stays almost the same. Oxford University researcher Felix Reed-Tsochas asked 24 students in the final months of school to list all their friends and relatives and say how close to them they were. The pupils filled in the questionnaire(问卷) twice more after starting work or going to university. They were also given free mobile phones and agreed that researchers could use their bills to work out who they called, when and for how long. Putting the two pieces of information together showed, unsurprisingly, that most people have a small circle of close friends, who they spend most of their time talking to. This inner circle is surrounded by group after group of ever more distant friends. As the volunteers' lives changed, this overall pattern, including the number of best friends, remained almost the same, meaning that some close friends from childhood were dropped or downgraded as new friendships were built. Dr Reed-Tsochas said: "Maybe my best friend is no longer the same person but the amount of time I allocate(分配) to my best friend is still the same." He added that this finding suggests that even with the coming of modem technology we are only capable of forming a limited number of true friendships. Chester University researcher Dr Sam Roberts said: "Our results are likely to reflect limitations in the ability of humans to keep emotionally close relationships both because of limited time and because the emotional capital(情绪资本) that individuals can allocate between family members and friends is limited.
