growing conditions encouraged farming traditions that have, in places, been enduring
having been done/having done——要求不能做定语，这题that having作定语修饰修饰farming traditions错错错

这个。。。怎么和我的记忆有偏差。。。
我记得prep里是说noun+having done是错的，一定要改成noun+that has/have done的。。。

同意。

为啥讨论这么多呢，OG里不是说
the use of present perfect progressive is not grammatically incorrect, but it is rhetorically inappropriate and sounds exaggerated...
就是嫌弃完成进行时有点过了、强调的力量有点重

Lynsey玲

have endured强调过去的动作产生的影响一直持续到现在
have been enduring更强调enduring这个动作一直在发生

哇，lynsey玲的解释真是醍醐灌顶啊。应该就是这样了！

关于E选项
E: have been enduring
have been + VERBing serves to express a CONTINUOUS ACTION.
Here, to endure means TO LAST.
To last is an action that -- on its own -- is continuous.
Since to endure on its own conveys a continuous action, the use of a continous tense seems redundant.

也就是说endure和现在完成进行时要传达的动作一直在进行，是重复的，所以redundant，所以OG说用力过猛

感谢！

总结下前面大神的，不能用have been enduring ,有两个原因：
1, 动作并没有持续到现在(前面encouraged )
2.  endure 本身就有持续的意思，所以have been enduring 就重复了。

在曼哈顿里面有明确说明，have done 可以表示一个动作已经结束，但是对现在还是有影响的。
比如： The boy has drawn a square in the sand.
( the boy is no longer in the act of drawing, but the square is still there. If the square has disappeared, use simple past.
