1 D having been asked是完成加被动的结构,独立做状语,表示这个动作在主句的动作之前发生,那么主句的主语就应该能够发出speak这个动作,比较一下四个选项的主语就可以看出来,只有D答案的主语是人,能够speak
2 B 虚拟语气的用法
出现desire和desirable的句子,宾语从句或表语从句中都用should do这个形式做谓语,should可以省略

1d 主谓一致,是smith 被ask
2that- clause省略" should”表示建议,虚拟语气

D
前面的独立主格结构没有自己的主语,所以应该和主句主语一致,都是Smith
C
虚拟。如果他放弃努力的话是让人满意的结果。

D
前面一句的主语省略了,但是明显是Smith
B
it is +adj(一类特定的形容词,表达愿望、要求等)+that 从句
这个结构中,从句为虚拟语气,谓语动词要用原形
