前面有didn't,后面的动词要不要变过去式?先说声谢谢了 be动词变过去式后,后面的动词要不要变? I didn‘t 后面应该加什么形式的动词 为什么didn't 后面要跟动词原形 didn't后面动词用原形还是过去式?句子中的didn't后面的动词用原形还是用过去式? chat变动词要不要双写t i didn't sleep until he came back.句子改错!要不要改为i didn't go to sleep until he came back.因为until用在否定句子中间前面应该用短暂性动词 i didn't sleep until he comes back.句子改错!要不要改为i didn't go to sleep until he comes back.因为until用在否定句子中间前面应该用短暂性动词 didn't后面动词什么时态? Didn't you go there?这句里面有了前面的did的过去时 后面的go就必须用动词原形是吗? I didn't know you ____(like) opera.用like的一个时态填空按说前面有了didn't,后面动词应该直接用原型like,但是正确答案是用liked,这是为什么呢 did后面的动词要加过去式吗,那didn't呢还有don't呢,要加过去式吗 如果一个句子里既有does（do）又有like那后面的动词要不要加ing,还是原形?比如说：比如说：I don't like . didn't 和doesn't 后面跟的动词是什么形态还有will won't那些 一般现在时后的动词要不要跟着主语变掉? used to do的否定used to do正式的否定形式是used not to do,口语中可以说didn't use to do .我想问,其他动词的否定都是在其前面加didn’t或者don't等助动词,为什么used to do的正式的否定形式要在used后面加 Didn't have any apples/apple.前面还是后面的正确?Didn't have any apples/apple.Thanks! 我对我的英语课本有个疑问课本里有一句话说： I didn't dare open a window. 在这里dare 若是情态动词,那前面为什么加didn't? 若是实意动词,怎么open前不加to?
