2.Whom is it that you would rather ___ to,David or me?
A.to apeak B.have spoken C.have speak D.speak
两道题的答案分别是A和B,我不能明白,
答
1 这题考的是伴随状语短语ask for his help 是说向某人请求帮助
2 rather后面加原形动词，排除a，have加完成时，排除c，此举的意思是这是谁已经告诉我的，所以选择have便是已经发生。

问题1考察“伴随状语”，选A 可以使用排除法，看句子时态，可先排除B 项，再看ask for one's help ，又可排除D 项，最后排除C 项，因为一个句子中两个动词必须用and 等连词连接，所以亦可排除…
问题2是句型would rather +do 的考察，C 项明显错误，可排除，剩余选项经对比可简单得出答案是D (质疑答案为B )
