「forget」、「regret」和「remember」的用法

當 forget、regret 和 remember 接的是動名詞，動名詞指的是比主要動詞還早發生的動作。在這類句子中，動名詞可以被現在完成分詞取代，以讓動作的次序更明確。forget 經常和 never 一起用於未來簡單式。

I remember locking the door. = I remember having locked the door.
He regretted speaking so rudely. = He regretted having spoken so rudely.
I don't remember losing my glasses. = I don't remember having lost my glasses.
I will never forget meeting my boss for the first time.

當這些動詞接的是不定詞，不定詞意指跟主要動詞同時發生的動作，或比主要動詞稍晚一點發生的動作。

This morning I remembered to lock the door. (= the remembering came first, then the locking)
Do not forget to buy some eggs. (= the not forgetting comes first, then the buying eggs)
I forgot to bring my books to school. (= first I forgot, then I didn't bring my books.)
We regret to announce the late arrival of the 12.45 from Paddington. (= our regrets come before the announcement)
