【分析】首先判断句子时态，本题所有句子描述经常性、习惯性动作，使用一般现在时。解题分三类情况：1. 主语为第三人称单数（如单数名词、he/she/it等）时，动词需变为第三人称单数形式；2. 主语为非第三人称单数（如复数名词、I/you/复数主语等）时，动词用原形；3. 注意固定搭配：be good at后接动名词（doing），want后接不定式（to do），go后接动名词构成固定短语（如go swimming）。
【解析】1. 主语My sister是第三人称单数，一般现在时，like变likes；2. 主语Bobby是第三人称单数，play变plays；3. 主语Yang Ling是第三人称单数，have的三单形式为has；4. 主语The girl是第三人称单数，wash以s结尾，三单加es，变washes；5. 主语The little rabbit是第三人称单数，eat变eats；6. 主语She是第三人称单数，dance变dances；be good at后接动名词，故dance变dancing；7. 主语My grandpa是第三人称单数，watch以ch结尾，三单加es，变watches；8. 主语Children是复数，动词用原形dress；9. 主语Miss Wu是第三人称单数，teach以ch结尾，三单加es，变teaches；10. 主语Su Hai and Su Yang是复数，动词用原形sleep；11. 主语Julia是第三人称单数，want变wants；want to do为固定搭配，故sing变to sing；12. 主语Mike是第三人称单数，go变goes；go swimming为固定短语，故swim变swimming。
