有没有变化格式要求?否则有很多种变化形式,如：
= Mr Green's favorite sport is basketball.
= Basketball is Mr Green's favorite sport.
= Mr Green likes playing basketball than any other sport.
= Mr Green likes playing basketball than the other sports.
favorite是形容词,意思是“最喜欢/喜爱的”,构成固定短语：one's favorite + 名词.
楼上不使用所有格形式Mr Green's,答案错误.
