play过去式为什么是played?

play过去式为什么是played? We had great fun _____ in the park. A .play B.played C. playing D. to play为什么是C? Did she practice __C__the piano at home? --no ,she went to the party. 帮我分析下这道题 谢了A.play B.played C.playing D.to play 请帮我解答下为什么是过去式的句子里要用ing形式 英语! Not a single game ------at yesterday's party.A. we played B.played we C.did we play D.we did play为什么是c而不是B呢?什么时候要加助动词do? 我需要所有英语动词的过去式如：play-played劲量多, played的过去式是 play过去式 play过去式 play 过去式 He played basketball yesterday.(把时间状语从句改为in two hours)He ___ ___ to play basketball in two hours.答案为什么是is going? 英语,下面这个【play】用的是【过去式】还是【过去分词】?有什么区别?【I played basketball yesterday!】 I played ping-pong quite well, but I haven't had time to play since the New Year.haven't 后为什么加had , play 为什么是原型? 谢谢 为什么动词过去式直接跟在主语后面?还有一般现在时也是.例：I played football.I play football.play前面为什么不用加助动词之类的词? had后面跟原型还是过去式选择题;they had great fun _____on the beach.A.to play B.playing C.play D.played Edward,you play so well.But I didn’t know you played the piano.1 为什么是：I didn’t know ,而不是I don’t know 2 即使用I didn’t know ,那么后面played也应变成play吧? 英语中一个句子前已经有过去式了后面的那个动词也要用过去式吗?比如I saw he ____ balls yesterday.是played,playing,to play 还是play? stand的过去式为什么是stood? miss的过去式为什么是+ed的
