be good at piano还是be good at the piano

问题描述

精选答案

正确答案是：be good at playing the piano！具体解析如下：be good at sth. 擅长某事，be good at doing sth. 擅长做某事。标题句提问意思是：“擅长弹钢琴”，因此要用短语：be good at doing sth.

另外：还要注意，表示“弹琴”，play后要加定冠词“the”；而表示“打球”，play后不用加定冠词“the”！例句：

I liketo play the piano.

He is good at playing soccer.
