原文如下:we have found that carbon copies can be made with better than average writing if the right edge of the wrist bone is allowed to touch the desk top and act as a kind of pivot. The same position is both proper and helpful in writing at a counter or with a heavey suit or overcoat. 我想只要保证是前臂肌肉运笔， 手腕用来稳定还是可以吧
