The approach usually used to distinguish individual replicons from fused eyes is to rely on stretches of DNA in which several replicons can be seen to be active, presumably captured at a stage when all have initiated around the same time, but before the forks of adjacent units have met.

区分独立复制子与熔化眼的常用方法是依靠DNA的伸直，因为在其中几个复制子能够发现具有活力，假设当所有的复制子在相同时间内已经起始时在同一状态时被观察，但必须在连接单位的复制叉相遇之前。

There are a multitude of reflex circuits in the central nervous system; a familiar one is the knee tendon reflex (straightening of the leg after tapping the knee with a hammer).

中枢神经系统有许多的反射回路，其中之一就是膝跳反射（用小锤轻击膝盖，腿会伸直），当用小锤轻敲肌腱的时候，大腿前大块肌肉的感受器感觉到肌肉的伸展。

Extend your arm straight away from your body, keep your shoulder still, and swing the arm side to side.

People with hyperextended knees usually have weak quadriceps, or do not tend to engage them fully in straight-legged poses like Tadasana and Trikonasana.

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。
