PAST SPECULATION: NEGATIVES 對過去的推測:否定句
常有“如果沒……的話,大概會……吧/大概就不會……吧”的推測。
其形式如下所示:
If+主語+had not +過去分詞, 主語+would (not) have +過去分詞
例如:
If they had not cheated they would have lost.
如果他們沒有作假,大概就會輸掉這場比賽吧。

常縮寫成下面這樣:
If they hadn’t cheated, they would’ve lost.
If they hadn’t cheated, they would’t have won.
