帮我看一道改错题 谢谢阿

The meeting was a great success.
The meeting was very successful.
The meeting was greatly successful. (如果一定要用great的话，就这么用，不过很牵强，但是要记住的是形容词一般不修饰形容词，修饰形容词的时候要用副词，但是多个形容词放在一起倒是可以修饰名词，如 a handsome young man)

The meeting was a great success.

The meeting was successful.都对

要变成successful，
那就要改为：
The meeting was successful。

答案的改法是把success翻译成成功的事，这是它是可数名词。
你的改法也可以，successful是形容词嘛。

success在做名词时可以解释为好结果。
successful是adj.
great也是adj.
估计两者不能互相修饰吧。
