我知道want sb to do sth中,动词不定式是做宾补,我想问一下,我要把TO后面的理解为动词不定式表目的对吗,为什么,比如I want you to have lunch,to have lunch理解成动词不定式表目的，

ask sb do sth有这一说吗?我知道还有 ask sb to do sth 直说do sth Want sb to do sth/want to do sth want sb to do sth 和want sb doing sth 的区别我觉的主要的区别是,现在分词表进行. 不知道对不对? 用want sb to do sth 造句 want sb to do sth同义句 want sb.to do sth.造句 want sb to do sth的意思 want sb to do sth的意思 want sth want to do sth want sb to do sth 造句want sthwant to do sth want sb to do sth造句 want sb to do sth与want sb do sth 与want sb doing sth有什么区别,怎样用? want sb to后面接do sth还是doing sth 用下列句型造句tell sb. to do sth.ask sb. to do sth.want sb. to do sth. 是want sb do sth 还是 want sb to do sth? want sb to do sth 和want sb do sth 区别 是不是want sb do sth?还是,want sb to do sth?还有tell want sb doing sth 没有这个句型吧?want sb doing sth /want doing sth没有这个句型吧?我只记得是to do. 我知道 hope to do,但我想问有没有hope sb to do sth、hope sb do sth、hope sb doing sth? 有没有人知道关于英语方面的公式啊?比如说：want sb.to do sth.
