英语翻译
A warm salute on the cheek,a quick hug,as she would demand of her father were he to go away.
father 是神父.谁帮我翻译并讲解下这句话的结构?是倒装吗,怎么看不懂
语境 ：He had never kissed anyone as a lover,did not want to now; nor,he thought,did Meggie.A warm salute on the cheek,a quick hug,as she would demand of her father were he to go away.She was sensitive and proud; he must have hurt her deeply when he held up her precious dreams to dispassionate inspection
were he to go away是什么结构啊 从来没见过,怎么 were 后面跟着个he
语境是,这个father神父,要走了要去别的地方 女的喜欢他.在告别
后来给你的问题，我没看到你的回答，以为你收不到信息。就又问了。呵呵，你很厉害啊。
怎么你们都能看出来是虚拟语气+省略呢，我就看不出，郁闷

答案

were he to go away这是虚拟语气,表示"要是/假如"他打算离开的话.
