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
