[我爱记单词]do well in的用法

be good at 后加http://www.so.com/s?q=%E5%90%8D%E8%AF%8D&，http://www.so.com/s?q=%E4%BB%A3%E8%AF%8D&或http://www.so.com/s?q=%E5%8A%A8%E5%90%8D%E8%AF%8D&。如;He is good at English (singing).
而do well in 后面跟V+ing。

或者这样解释:good是http://www.so.com/s?q=%E5%BD%A2%E5%AE%B9%E8%AF%8D&，well 是副词。

感谢你的帮助
