Read "The Funny Little Fellow" and answer the question that follows.   The Funny Little Fellow by James Whitcomb Riley     'Twas a Funny Little Fellow   Of the very purest type,     For he had a heart as mellow   As an apple over-ripe;     And the brightest little twinkle   When a funny thing occurred,     And the lightest little tinkle   Of a laugh you ever heard!       His smile was like the glitter   Of the sun in tropic lands,     And his talk a sweeter twitter   Than the swallow understands;     Hear him sing - and tell a story -   Snap a joke - ignite a pun, -     'Twas a capture - rapture - glory,   And explosion - all in one!       Though he hadn't any money -   That condiment which tends     To make a fellow "honey"   For the palate of his friends; -     Sweet simples he compounded -   Sovereign antidotes for sin     Or taint, - a faith unbounded   That his friends were genuine.       He wasn't honored, may be -   For his songs of praise were slim, -     Yet I never knew a baby   That wouldn't crow for him;     I never knew a mother   But urged a kindly claim     Upon him as a brother,   At the mention of his name.       The sick have ceased their sighing   And have even found the grace     Of a smile when they were dying   As they looked upon his face;     And I've seen his eyes of laughter   Melt in tears that only ran     As though, swift dancing after,   Came the Funny Little Man.       He laughed away the sorrow,   And he laughed away the gloom     We are all so prone to borrow   From the darkness of the tomb;     And he laughed across the ocean   Of a happy life, and passed,     With a laugh of glad emotion,   Into Paradise at last.       And I think the Angels knew him,   And had gathered to await     His coming, and run to him   Through the widely-opened Gate -     With their faces gleaming sunny   For his laughter-loving sake,     And thinking, "What a funny   Little Angel he will make!"   Which best describes Riley’s tone in this poem?单项选择题
