把“Jill often do sth.” 改成一般疑问句对不起，问错了。是改否定句

把“Jill often do sth.” 改成一般疑问句对不起，问错了。是改否定句 often to do sth,often doing sth,还是ofthe do sth?原因,谢谢! sb often do.是Sb often do sth.还是Sb often doing sth.哪个正确? 经常做某事的英语是often to do sth.还是often do sth. how often用法 how often do you do sth?or how often you do sth?还有time through的意思 more often than not do sth.怎么翻译 Jill often helps her mother with housework?改成_______ ______ Jill often ____ with houework? 有没有动词或名词后面加often 或者do sth often的说法?如题 sb.with sb.often do sth.中的do是原形还是第三人称? keep有keep doing sth.keep do sth .keep to do sth .请把用法和例句留下 英语句型中Do,sth.Doing,sth.To,do,sth.要怎么区别啊?我老把它们混乱 do sth to do 关于初二英语语法的问题（often)see sb.do sth.如果人称是单三,do会有时态变化吗? help somebody do sth中的do需要用第三人称单数吗?如She often help her mother do/does homework是do 还是 does? -----sb to do sth 和 -----sb do sth请把所有关于这两个结构的常用单词列出来. 英语句型转换decided to do sth把decided to do sth 转换成另一个英语句型 What does Jill do with her family and relatives? when sb.do sth.还是 when sb.doing sth.如When my mother ________(cook) meals for us in the kitchen I often go there to help her.
