Doesn’t to be trying that again and again irk you? 此句结构不符合语法规则。我改一下结构,你就明白了: Doesn’t it irk you to be trying that again and again? 这是动词不定式短语作句子的真正主语,不定式用了进行体,it 作形式主语。
如果不定式作真正主语在句首,疑问句需要变换一下格式,用 it 作形式主语,不定式后置。我演变一下句子的来历: To be trying that again and again irks you. (不能直接变疑问句) 先换成形式主语: It irks you to be trying that again and again. 然后变疑问句: Does it irk you to be trying that again and again? 然后再变反问句: Doesn’t it irk you to be trying that again and again?
