你前面的两个例子好像有个别词写错了，应该是：1.we come here on sunday2.you play computer games everyday.变成否定句、疑问句和第三人称单数后分别是：否定句：1→we don't come here on sunday。
2→you don't play computer games everyday。疑问句：1→Do you come here on sunday？
2→Do you play computer games everyday?第三人称单数：1→He comes here every sunday。
2→He plays computer games everyday。
