      核心提示:In the present tense we use can to talk about a general ability e.g. I can swim and also for ability at a particular m

      In the present tense we use ‘can’ to talk about a general ability – e.g. I can swim – and also for ability at a particular moment – e.g. I can see you! The rules for talking about past abilities are different.

      現(xiàn)在時態(tài)里,我們用can去談?wù)撘话愕哪芰,例如I can swim。還有形容在一個特定的時間的一種能力,例如I can see you!但談?wù)撨^去的能力是不同的。

      當(dāng)我們談?wù)撃硞特定場合不能做某事的能力時,我們用wasn’t /weren’t able to, didn’t manage to, 或是couldn’t

      • I would have been able to win the race but I fell over.
