不可捉摸

The affection on the network, ambiguous and be not allowed to fathom as well, probably lets me feel realer.

在网络上，暧昧而又不可捉摸的感情，或许让我觉得更真。

One step is to gauge the resilience of ecological networks such as food webs - in particular, their capacity to withstand disturbance and species loss.

我预言，到2020年，生态理论将越来越专注于生物体的通常不可捉摸的生物学的详情，以及演化动力学的启示。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
