这里有些错误sincere最高级,应该是sincerest,不过也有人会用Most sincere,所以这不算特别严重的错误.devout前面有the,那么应该是想用最高级,所以应该是the most devout action.hide前面加to,  tend to use, use...那正确的是怎么？这样是否合适People tend to use the most sincere appearance and the devout action hide a heart demon "改成：People tend to use the most sincere appearance and the most devout action to hide a heart demon就好了
