论文部分内容阅读
1. pull是三者中使用最广的词，指使物体朝着发出力的方向移动，不强调用力的大小和方式。它比“draw”一词所表达的“拉”要费力一些。
The mother pulled the little girl by hand.
She pulled her chair up to the desk.
2. draw表示不论用力大小而作出平稳的动作。指把某物体朝着出力的方向拉。意思与pull相近，但动作比pull均匀、从容，没有pull所表述的“拉”那么吃力，语体也比pull正式。
I don’t know how to draw the net in.
Out of the school bag he drew a piece of paper and gave it to me.
3． drag指艰难而缓慢地拖、拉较笨重的东西，需要付出努力以克服阻力、摩擦力或重力。运动方向可能是水平或沿斜坡而上。
That night I dragged myself along the street.
Mother dragged a trunk out from under the bed.
