易放苏诺： don't. do, be, have 这三个词词性是类似的,都是表示时态用的.只有这样的词后面才能跟not.还有情态动词,如must,can,may,should等,表否定时也是后跟not. 一般的行为动词,在一般现在时中,是前面省去了do,比如说,he jumps,完全...
泰山区17612219512： I hope I haven't failed.为什么两个动词连用 - ？
易放苏诺： 完成时态的固定用法,have或者其变形+动词过去分词
泰山区17612219512： I haven't heard from him last week. - ？
易放苏诺： A since的用法主要有两点:一是表示“自从……以来”,二是表示“既然”之意.但如果只了解词的含义,而不了解其用法,在使用时就会造成错误.例如:I have not heard from him since I lived in Shanghai. 不少人会望文生义,将该句译为:...
泰山区17612219512： if we haven't 和if we hadn't在用法上有什么不同?？
易放苏诺： 不能啊,因为后边是we should be……这是虚拟语气,虚拟语气的句子里,格式是if +主语+过去时,如果虚拟语气表达的是与事实相反,那么就用If+主语+had+done,比如: If I had gotten there earlier,I should/would have met her. 如果我早到那儿,我就会见到她. (事实:去晚了) 所以无论怎么看,都不能用have

泰山区17612219512： 英语里面whether来历谁能讲一下 - ？
易放苏诺： if和whether都可译为\＂是否\＂,二者引导宾语从句时通常可以互相替换,口语中多用if代替whether.例如:Ask if/whether he plans to come to the meeting. 而以下几种情况中, 只能用whether:1. 强调两方面的选择,特别是句中有or not时.如: ...
泰山区17612219512： if 引导的条件状语从句 - ？
易放苏诺： IF引导的条件状语从句,后半句即主句为将来时,从句则应为现在时.例如:If he walks to school at 6:50am ,he will be late for school.(这里引导未发生或可能发生的事,表事情发生的条件)IF有时候也引导虚拟语气例如:If I were you, I would go ...
泰山区17612219512： ”如果没有遇见你“”的英语是if didn't met you 还是if haven't met you? 哪个正确啊? - ？
易放苏诺： 先纠正一下你的拼写错误,是meet,不是met.(第一句) 一般的话就是:If i didn't meet you 如果虚拟语气就是:If i haven't had met you
泰山区17612219512： if作为条件状语从句连词是如果时,后面加any还是some? - ？
易放苏诺： 用any还是some,与条件从句无关,而是跟有这个动词的疑问与否定有关,也就是have 和there be,比如I have some cats. Do you have any cats? I haven't any cats. 又比如There are some books on the desk. Are there any books on the desk? There are not any books on the desk.
