右手

Yet about 90 per cent of every human population that has ever lived appears to have been right-handed.

现在每种人口的大约90%在任何时候都显示出惯用右手。

It is possible that our tendency for right-handedness goes back to early human history.

我们有两只手，但是为什么大多数的人只用右手书写以及从事其它困难的活动呢？

In this case, right-handedness is defined as any positive axis pointing toward the viewer.

在这种情况下，右手系就定义为任意轴的正向均指向观察者。

If asked to explain the significance of this preference most people reply that it is obviously the result of the predominance of right-handedness in the population.

如果被提请解释这一偏爱的意义时，大多数人会回答说，显然这是人们以右手为主的这种优势造成的结果。

Age, sex, gender, left or right-handedness and nationality cannot be determined from handwriting.

年龄、性别、左撇子或惯用右手和国籍都无法从签名上加以判断。

So the bottom line is, we have a good general idea of the causes of right-handedness in human populations, but we have yet to work out the precise details, including why the direction is right instead of left.

所以基本点就是：对于人口中"右利手"的原因，我们有一个好的总体的观点，但是我们还需要找出精确的细节，包括为什么"利手"是右手而不是左手。

Results: Both females and males were found to have a trend of increasing age with a more degree toward right-handedness, and the changes became more obvious either before age 20 or after age 60 years.

结果：不论在男性或女性均可发现有随著年龄增加而有偏好使用右手的趋势，而这种趋势在年龄小於20岁和大於60岁尤其明显。

Why do humans, virtually alone among all animal species, display a distinct left or right-handedness?

为什么人类，事实上在所有的动物物种中独一无二地，显示出惯用左手或是右手？

But right-handedness dominates the population far more, about eight-to-one, so that's either not related or it's affected by cultural influence.

不过，惯用右手的人在人群中的优势却要大得多，他们与左撇子的比例大约是8：1。由此可见，左右手偏好要么与前述偏好没有关联，要么就是受到文化的影响。

Schizotypal subjects, especially those with the positive aspect of schizotypy, would be more likely to be away from the right-handedness.

拥有精神分裂病性人格者在惯用手表现上会有不同於一般人典型右手的表现，特别是在具有精神分裂病性人格之正性症状表现的人。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
