Aren't they?老师曾说,动词后面的人称代词为宾格,这里的they为什么不是它的宾格them呢? Everything后be动词用单数,但用they来代替,如：Everything is right,aren't they?是这样表达吗? 关于不定式的否定问题 to not 与 not to 区别?-They are quiet,aren't they?-Yes.They are accustomed ___ at meals.to not talking但是参考书上又写说 非谓语动词的否定式均在to前加not 那本题为何在to后加not呢 是不 No,they aren't是什么意思 ()()sad?No,they aren't No,they aren't单数 英语翻译Aren't they beautiful! they aren't的音标^^ They aren't friendly同义 There is/are 后动词要加ing,那么there isn't/aren't 后呢 NO,they aren't.they're lions. They are drinking wine,aren't they? everyone is happy反义疑问句为什么我们老师说的是Everyone is happy,aren‘t they? 英语翻译daejae is real,aren't they? ()(that)are apples.They aren‘t oranges. The cat aren’t ---------------------.They are -----------. there are .反问句式 aren't they No, they aren't.改为单数形式
