I did nothing but watch TV这句话的语法点为?主要想问 后面的but 什么时候接 do ,什么时候接todo请举例一句用到to的

I did nothing but love you do nothing but 用法Last night i did nothing but watch TV. i did nothing but sleep yesterday.but后是条件状语从句吗? I want nothing but I ( ) but I saw nothing I have nothing but you. I listened but----------(hear) nothing. i tried but got nothing. I can do nothing but he did nothing but do中but的词性? last sunday morning ,i did nothing but _(write) 请问此空格里填写原型还是动词ING形式? I receivd a letter writing in green ink.She did nothing but cried all day.这些哪里错了 “but”用法.我们说“but”前有实义动词do时,其后的不定式省去“to”.请比较：1、I did nothing but watch TV last night.2、The doctor told him nothing but to stop smoking. 找错i heard but i listened nothing Nothing I want Nothing I love but for my demon I have been asked to a party,but I have got nothing to wear.这个句子中的have been asked为什么不能换成wa asked?这一类的时态题该怎么作? They did nothing but cried all day.错在哪 she did nothing but cried all day哪错了?
