今天在教辅书上看到一题,Thinking back on the past years ,I worked so hard at English , so I am good at sopken English now .这是不是错的?be good at 后面不是要跟ing形式吗
答
be good at doing sth ( 介词后的动词用ING）
注：SPOKEN English 是英语口语,不是说英语
Thinking back on the past years ,I worked so hard at English ,so I am good at sopken English now是对的.
区别：He is good at singing .
