英语中，没有practise to do这种表达方式，只有practise doing的表达方式。
practise doing sth意思是“练誉坦习做某事”，practise也可以是practice。例如：
Then for a period of several weeks we practise doing the play.
随后的几庆携桐个星期我们进行隐物排练。
When he finished doing his homework, he went on to practise playing the piano.
他做完作业后，接着又练习弹钢琴了。
Practice doing the things you are unsure about.
对自己不确定能做的事要练习。
