Question

20．I ______ sooner but I didn't know that they were waiting for me．（　　）

• A． had come
• B． was coming
• C． would come
• D． would have come

Answer 1

分析 句意：我本来可以早一点来，但我过去真不知道他们正在等我．

解答 答案D．由but I didn't know that they were waiting for me 可知"我"事实上并没有早点来，因此可推知第一句应该是一个虚拟语气的句子．因为讲述的是过去的事情，所以句子应借助于"would+have+过去分词"的形式．本句可以理解为：I would have come sooner if I had known that they were waiting for me．故选D．

点评 本题考查虚拟语气．解答此类题目首先根据上下文语境找到隐藏的条件，转换成if条件句中的虚拟语气来理解，然后判断是对哪种情况的虚拟，从而来确定谓语动词的形式．
