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：我本來可以早一點(diǎn)來，但我過去真不知道他們正在等我．

解答 答案D．由but I didn't know that they were waiting for me 可知"我"事實(shí)上并沒有早點(diǎn)來，因此可推知第一句應(yīng)該是一個(gè)虛擬語氣的句子．因?yàn)橹v述的是過去的事情，所以句子應(yīng)借助于"would+have+過去分詞"的形式．本句可以理解為：I would have come sooner if I had known that they were waiting for me．故選D．

點(diǎn)評(píng) 本題考查虛擬語氣．解答此類題目首先根據(jù)上下文語境找到隱藏的條件，轉(zhuǎn)換成if條件句中的虛擬語氣來理解，然后判斷是對(duì)哪種情況的虛擬，從而來確定謂語動(dòng)詞的形式．
