被认为没有用处

He had lost the sense of what the Chorus was in the hands of the great masters, say in the Bacchae or the Eumenides. He mistakes, again, the use of that epiphany of a God which is frequent at the end of the single plays of Euripides, and which seems to have been equally so at the end of the trilogies of Aeschylus. Having lost the living tradition, he sees neither the ritual origin nor the dramatic value of these divine epiphanies. He thinks of the convenient gods and abstractions who sometimes spoke the prologues of the New Comedy, and imagines that the God appears in order to unravel the plot. As a matter of fact, in one play which he often quotes, the _Iphigenia Taurica_, the plot is actually distorted at the very end in order to give an opportunity for the epiphany.

亚里士多德还忘了合唱队是由那掌握命运者来控制，比如酒神的女祭司或者复仇女神欧墨尼得斯；他弄错了神的显现的用处，欧里庇德斯的单幕悲剧结尾处常有神显现，埃斯库罗斯三部曲的结尾好像与此相似，由于失去了活生生的传统，亚里士多德没有意识到神灵显现的仪式渊源和戏剧价值，而把神认为是有时去朗诵新喜剧开场白的这样一种方便和抽象，想象神的出现是为了解开情节的死结，而事实上，在他经常引用的《在奥利斯的伊菲革涅亚》里，情节实际上在结尾处被搅乱，目的是为了给神一个显现的机会。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
