as never before in their long history
universities have become instruments of national competition.They are the place of the scientific discoveries that move economies forward,and the primary means of educating the talent required to obtain and maintain competitive advantage
最后一句中的require为什么不用主动 如果用被动 为什么and连接的从句后面没有be动词are?
equired用了被动形式表示被要求的,此处修饰了“talent”,译为“所要求的才能”
and连接的从句中,maintain与obtain是并列的
