I spend two ours practicing playing the piano.是个什么用法
I spend two ours practicing playing the piano.这里,practice是名词,practicing是形容词,是“开业的,在工作的”的意思.这样的用法是不是错的?又,假设把practice换成practise再加ing,可后面又跟playing,这是什么用法啊?
我问的是1.practicing是不是应该用practising？2.practicing playing 或practising playing 这样连用是不是错了？

I spend two ours practicing playing the piano.是个什么用法I spend two ours practicing playing the piano.这里,practice是名词,practicing是形容词,是“开业的,在工作的”的意思.这样的用法是不是错的?又,假设把practic
spend time/money doing sth.(花时间/钱做某事) practise意为：练习
practise doing sth(练习做某事)
我花两个小时练习弹钢琴.
英国英语practise(动) pracitce(名词)
美英 practice(名词,动词)
practising/practicing doing sth 没错误

不是错的啊。spend some time doing sth.是固定搭配 practice和practise都是一样的！！！而且practice doing sth也是一个发、固定搭配其他人不是早就说了吗

用的spend some time or some money (in) doing sth.两个词都是练习的动词，一样的

I spend two hours practising playing the piano . spend sometime doing something . practise doing something.这是两个语法。

pracise和practice都可以做动词，后面跟doing所以都是对的

spend sth （in）doing 固定搭配花费某物（时间金钱。。。）做某事 practice doing sth 练习做某事 practicing和playing都是因为语法要求由动词变为分词 practice practise应该没区别吧

您好！很高兴为您解答！
翻译：我花费了2个小时弹钢琴。本题主要考查spend的用法：spend some time/some money (in)doing sth.花费时间/金钱在做某事上因为play是动词，所以本句应该是：I spend two ours （in）practicing playing the piano。in 省略了
spend some time/some ...
