Learning to touch type is hard.

学习触摸式打字很困难。

Oh, I'm trying to learn to touch type.

哦，我在努力学习触摸式打字。

No, no, I really like, and when I type I could type really fast, touch type, but I cannot move my thumb that fast.

不是，我在电脑上打字时，速度可以非常快，可是在触摸屏上打字，我的拇指动不了那么快。

Even if you're able to touch type, just wiggling the fingers is not the same as engaging the whole muscle of the arm and handwriting.

即使你能够触摸文字，仅仅摆动手指并不等同于让手臂的整个肌肉和书写过程参与进来。
