got a so great role 应该是这样。great 形容 role，so是副词，修饰great。第二句，应该用there be句型。There is a man stand out of the door wearing a mask on his face.普通语序Out of the door there is a man with a mask on his face.强调语序Out of the door there is a man who wears a mask on his face.强调语序加从句。如果要用从句，那么who后面用的词格和主语一致，所以要加s。用一般现在时即可。...
