traditions have endured sth. 是说traditions对这个东西的影响效果从过去持续到现在。
traditions have been enduring sth. 这里enduring是V-ing,更有强调endure这个动词一直在发生的意味,并不好。因为,V-ing一般用于描述的是一个瞬间正在发生的事情,比如I am playing soccer right now.
以后再回述,就会成为I played soccer yesterday. 所以have been enduring就更强调endure这个动作,一直发生啊发生啊发生啊,但不同于have endured的意味是【这个动作过去发生过啊,然后影响一直持续啊持续啊持续啊】
