无缘无故

It's like a "cheap scare" in a horror film when out of nowhere a cat jumps out and delivers a low blow to the audience.

这就像恐怖片里，无缘无故跳出一只猫的「廉价惊悚」，趁观众不注意的时候，暗地里偷打一拳。

Both of these come from the same whys, their names should be mystically.

无缘无故，我们的世界就这样令人难以置信地开始了它永无止境的变化

她真是个傻帽，时常无缘无故的就傻笑起来。

And I also know that kids today don't just start smoking for no reason.

They were making her feel obscurely worried(= for reasons that were difficult to understand).

MR. PAIK: Why should I give you money without an explanation?

我凭什么无缘无故给你一笔钱呢？

But here's the rub, your looks will fade and my money will likely continue into perpetuity...

但是，这里有个致命的问题，你的美貌会消逝，但我的钱却不会无缘无故减少。

One would approach at first warily through the shrub oaks, running over the snow-crust by fits and starts like a leaf blown by the wind, now a few paces this way, with wonderful speed and waste of energy, making inconceivable haste with his "trotters," as if it were for a wager,and now as many paces that way, but never getting on more than half a rod at a time; and then suddenly pausing with a ludicrous expression and a gratuitous somerset, as if all the eyes in the universe were eyed on him —— for all the motions of a squirrel, even in the most solitary recesses of the forest, imply spectators as much as those of a dancing girl —— wasting more time in delay and circumspection than would have sufficed to walk the whole distance—— I never saw one walk —— and then suddenly, before you could say Jack Robinson, he would be in the top of a young pitch pine, winding up his clock and chiding all imaginary spectators, soliloquizing and talking to all the universe at the same time —— for no reason that I could ever detect, or he himself was aware of, I suspect.

有一只赤松鼠开始谨慎地穿过矮橡树丛，跑跑停停地在雪地奔驰，像一张叶子给风的溜溜地吹了过来；一忽儿它向这个方向跑了几步，速度惊人，精力也消耗得过了份，它用"跑步"的姿态急跑，快得不可想象，似乎它是来作孤注一掷的，一忽儿它向那个方向也跑那么几步，但每一次总不超出半杆之遥；于是突然间做了一个滑稽的表情停了步，无缘无故地翻一个觔斗，仿佛全宇宙的眼睛都在看着它，——因为一只松鼠的行动，即使在森林最深最寂寞的地方，也好像舞女一样，似乎总是有观众在场的，——它在拖宕，兜圈子中，浪费了更多的时间，如果直线进行，早毕全程，——我却从没有看见过一只松鼠能泰然步行过，——然后，突然，刹那之间，它已经在一个小苍松的顶上，开足了它的发条，责骂一切假想中的观众，又像是在独白，同时又像是在向全宇宙说话，一我丝毫猜不出这是什么理由，我想，它自己也未必说得出理由来。

The implication is evident from the nature of correlatives. Proof of the antecedent:(1) Some nature is contingent. It is possible for it to exist after being nonexistent, not of itself, however, or by reason of nothing, for in both these cases a being would exist by reason of what is not a being. Therefore it is producible by another.

对上述命题的证明如下：(1)某些本性是偶然的，其作为非存在之所以能够存在，不是因为它自身，也不是无缘无故，因为在这两种情况下存在似乎可以凭借非存在的理由而存在，因此它必然是另一存在的产物。

Among the people near the frontier, there was one skilled at prognostication. For no reason, his horse ran off into the territory of the barbarians; everyone consoled him.

靠近边界上的人里有个很会占卜的人，他的马无缘无故地逃跑进入胡人的领地去了，别人都来慰问他。
