C1
If + S + had + V3, S + would + V0 (now) · If + S + V2, S + would have + V3
高级阶段的时间混合条件句
讲解
条件句的两个分句不一定要在同一个时间点。if 分句用过去完成时、主句用 would V0，表示过去的事留下了延续到今天的结果。反过来，if 分句用一般过去时表示长期状态，而主句用 would have V3，表示一个已经发生的后果。 常见错误：不要下意识地把两个分句都套成同一个时间点：If I had taken the job, I would have been in Berlin now ✗（now 要求用 would be），I would be in Berlin now ✓。
例句
