首先需要纠正拼写：正确短语是 would sooner（而非“would sonner”）。
“would sooner”表示“宁愿；宁可；更愿意”，语气上和“would rather”非常接近（可互换），但有时更强调“优先选择”的决心。
结构：主语 + would sooner + 动词原形 (+ 其他成分)
例：
I would sooner stay at home than go out in the rain.（我宁愿在家也不愿冒雨出去。）
She would sooner walk to work than take the crowded subway.（她宁愿步行上班也不愿坐拥挤的地铁。）
结构：would sooner do A than do B（A和B均为动词原形）
例：
He would sooner resign than accept the unfair promotion.（他宁愿辞职也不愿接受这不公平的晋升。）
We would sooner eat leftovers than cook a new meal tonight.（今晚我们宁愿吃剩菜也不愿做新饭。）
当主语希望他人做（或不做）某事时，从句需用虚拟语气：
若从句描述现在/将来的情况：从句谓语用过去式（be动词用were）；
若从句描述过去的情况：从句谓语用had done（过去完成时）。
例：
I would sooner you didn’t tell him about our plan.（我宁愿你别告诉他我们的计划。）（现在/将来的虚拟）
She would sooner you had come to the party yesterday.（她宁愿你昨天来参加派对了。）（过去的虚拟）
They would sooner the meeting were postponed.（他们宁愿会议延期。）（be动词用were，更正式）
结构：would sooner not + 动词原形
例：
I would sooner not talk about this topic right now.（我现在宁愿不聊这个话题。）
He would sooner not drink coffee after 6 PM.（他宁愿下午6点后不喝咖啡。）
“would sooner”和“would rather”几乎完全同义，可互换使用。细微差异在于：
“would sooner”更强调“时间上的优先”或“更迫切的选择”（但日常用中差别很小）；
口语中“would rather”更常用，“would sooner”稍正式一点，但不影响理解。
