有关两个并列短语否定形式是not to do A,not to do B的词语有哪些,（如ask）

为什么ask sb to do sth的否定形式是ask sb not to do sth ask sb not to do 这个是我所学过的短语,肯定句decide to do sth ,否定句decide not do do sth 是ask sb not to do sth 还是ask sb to not do sth 如：try to do sth.变成否定形式为try not to do sth.在英语的其他跟to do的单词适用吗, prefer doing /to do sth,所以其否定形式是不是not to do / not doing ask/tell sb.not to do sth ask sb not to do啥意思? 有没有ASK SB NOT TO DO STH need to do的否定为什么不可以是 need not to do 是tell sb.not do sth.还是tell sb.not to do sth.那么ask呢? make sb do的不定式否定是make sb not do还是make sb not to do
