Classical music of the representative of Haydn, Mozart and Beethoven have
1. 主谓不一致,当然问题不止这一点.
2. 这句话想说：某某的古典音乐代表作有.若果真如此,该句则是一个我很想收录的典型中式英语的例子.那如何改呢因为不知你所要的确切意思，姑且修改如下：The representative works of classical music by Haydn, Mozart and Beethoven include...Included in the representative works of classical music by Haydn, ... are...这句话的意思应是 古典音乐的代表人物有:海顿、莫扎特和贝多芬那就：Haydn, ... are representatives ofclassical music composers.Haydn, ... are representative composers of classical music.
