C1Kata kerja modal22 menit
Modal perfect: menduga-duga tentang masa lalu
Modal perfects: speculating about the past
Pakai must have, can't have, might have, dan should have untuk menilai kejadian masa lalu dengan tingkat kepastian yang tepat.
Kita tidak selalu yakin tentang apa yang terjadi di masa lalu. Modal verbs + have + past participle memungkinkan kita menunjukkan seberapa yakin kita, atau mengomentari hal yang seharusnya atau tidak seharusnya terjadi. Di level mahir, kamu juga perlu menggabungkannya dengan bentuk continuous dan pasif.
| Arti | Bentuk | Contoh |
|---|---|---|
| Almost certain (positive) | must have + past participle | The lights are off, so they must have gone home. |
| Almost certain (negative) | can't / couldn't have + past participle | That can't have been Kofi; he's in Madrid this week. |
| Possible | may / might / could have + past participle | The keys might have fallen out of my pocket. |
| Possibly not | may not / might not have + past participle | He might not have heard the phone ringing. |
| Expected but did not happen | should / ought to have + past participle | The parcel should have arrived by Friday. |
| Unnecessary action | needn't have + past participle | You needn't have brought so much food. |
| Longer activity | modal + have been + -ing | She looked exhausted. She must have been working for hours. |
| Passive | modal + have been + past participle | The contract may have been signed last week. |
Perhatikan perbedaan antara couldn't have dan needn't have. Yang pertama menyatakan bahwa sesuatu mustahil terjadi (She couldn't have known), sedangkan yang kedua menyatakan bahwa suatu tindakan sudah dilakukan tetapi tidak diperlukan (You needn't have come). Selain itu, can have biasanya tidak dipakai dalam kalimat positif: pilih may, might or could have.
- The bridge can't have been built before 1900; the style is far too modern.
- I wonder why Dev did not reply. He may not have seen my message.
- We should have booked earlier. Now every seat is taken.
- You needn't have waited; I could have found the way myself.
