选A,这里是虚拟,现在时的虚拟回答用过去时
i'd rather=i would rather.
意思是：我宁愿干~事.后面直接跟动词原形.
eg:He would rather play than work.
他宁可玩,却不愿工作.
She'd rather die than give a speech
她宁愿死也不愿意听演讲
'Do you mind if I smoke?' 'Well,I'd rather you didn't.'
“介意我抽烟吗?”“恩,最好别抽”
当would rather做“宁愿”讲时,就表示虚拟,would rather sb do一般是用作一句话说,表示我宁愿.,不会用作回答,而且选项中也没有do的形式啊,这也是做题的技巧
