用括号说给的动词的适当形式补全对话hello! what's happened ?Didn't you catch your train? If I__________(catch) it I ________(not ,be) here, should I ?
had caught,wouldn't have been.
虚拟语气,表示与过去事实相反的情况
从句：主语+had+done
主句：主语+should/would/could/might+have done
例如：
1． If I had got there earlier,I should/could have met her.如果我早到那儿,我就会见到她.（事实：去晚了）
2．If he had taken my advice,he would not have made such a mistake.如果他听我的劝告的话,就不会犯这样的错误了.（事实：没有听我的话）
had caught
wouldn't have been
在if后如果与事实相反if后就用过去完成时had done
从句用现在完成时have done
“我将不会在这”是从句的意思，用将来过去形态will变为wound，后加have done
