1. D
翻译：昨晚我一到家,我就知道了那个坏消息.
解释：这是一个固定句型：No sooner...than...,意思是“一...,就...”.
其中含有no sooner的句子必须采用过去完成时,即谓语由“had + 过去分词”构成.而且如果no sooner提前至句首的话,则该句必须采用部分倒装,即把助动词had也提前.
而含than的句子只能使用一般过去时.
即：No sooner had I got home than I kenw the bad news last night.
= I had (no sooner) got home (than) I knew the bad news last night.
2. B
翻译：当看电视的时候,我们听到了门铃在响.
解释：此题考查状语从句的省略语法.
像while等所引导的状语从句,如果从句的主语和主句主语相同,且从句谓语以be动词开头时,则可以把从句的主语和be动词一起省略.
即：While watching television, we heard the doorbell ring.
= While (we were) watching television, we heard the doorbell ring.
其他答案ACD的主语都不是we,这时while从句就不能省略其主语和be动词we were.
dno sooner……than…… sooner后接的时态一定是这样，再加倒装
b主句从句主语一致，从句的助于才可以省略
B 这是no sooner引导的倒装句，所以首先排除A，再者由后面的knew知道是过去式，所以排除CD，然后句子前后有比较的含义，所以选B，did起强调作用
C while有“当·····的时候”意思，由句子可知是过去正在看电视的时候门铃响了，应该用过去进行时。...

1.D
NO sooner置于句首，所以句子要到装，又因为时间发生的先后，所以用had done的结构，属于过去完成时表发生顺序
2.B
属于考察句子主谓一致的题目
从主句“While watching television”可看出句子主语是“we”，而从句主语要与其一致，所以选B
