啊这！原来形容词变级还有这讲究～ 一般单双音节直接加er/est：tall→taller→tallest，big→bigger→biggest～ 但三音节及以上（比如difficult、interesting）就得靠more/most来带节奏啦 difficult → more difficult → most difficult interesting → more interesting → most interesting 还有那些-ed结尾的疲惫系形容词也一样： tired → more tired → most tired worried → more worried → most worried 一句话总结：长词不硬加，more/most安排上！
