was supped to do 和 is supposed to have done的区别,他两个小时前就该来了,应该用哪个句型,期待权威的回答,因为要参加高中考试 what was to do和 what to do区别 All i ever wanted to do was travel什么意思? what on earth was i going to do 翻译 I was nothing,so do not be afraid to lose. i asked her( ) the next yearAwhat she was going to doBwhat was she going to doCshe was going to do whatDshe was going to do I do not like him,but he was too good to me,how can I do? I was trying to do what the producer telling to do,telling在里面的语法是什么 mean to和mean to do分别在什么情况下才用”You should have thanked her before you leftI meant to ,but when i was leaving i couldn't find her anywhere:这里为什么不加do？ all i had to do was看到了一个句子,不太明白,All i had to do each day was take care of four kids,milk goats,and do the cooking.这个句子里面,was 和take 连接不是错误的吗.是不是就像 I was want a book 一样的错 All he did was （to help）the homeless children为什么要填 to do 课本上有一句和这个很相似 all i have ever wanted to do was (travel） 这不就是原型么. I really do not want you to just a memory,I was reluctant to you I was at a loss what to do.I have forgot which way to take. I really do not want you to just a memory, I was reluctant to you I was not sure/certain what I ought to do.为什么这样was not可以是I am not sure /certain what I ought to do. All I wanted to do was()was后面的括号中应加什么?是动词原型吗?all i wanted to do was travel这个对吗? All I wanted to do was sleeping.这里加was做什么? i do not state now,but i when i was a child 为什么填was used to
