過去完成式怎麼用?

內容簡介

「時態(tense)」 是英語語法中的一大難點。尤其是當一個句子中存在不同時態的時候,要想準確地把握句意,就需要理解每個時態的具體用法。我們用過去完成式談論過去某個時間點之前已經發生的事情。過去完成式的結構是什麼?當一句話中,過去完成式和過去式同時出現時,哪一個時態所描述的動作先發生?主持人 James 在 「一分鐘英語」 影片中用一個例句來講解過去完成式的基本結構和用法。

文字稿

Hi, everyone, I’m James and today we’re going to talk about the past perfect tense – how we form it, and why we use it!

「By the time I arrived at the airport, the plane had already left.」

In this example, 『had left’ is the past perfect tense. The structure for the past perfect tense is 『had’ plus a past participle.

There are two past actions – 『arriving at the airport’ and 『the plane leaving’. But which of these happened first?

The clue is the past perfect tense! The action in the past perfect is the action that always happens first.

Because the verb 『leave’ is in the past perfect, 『had left』, we know that this action happened first.

The action that happens second is often in the past simple tense.

In this example: I arrived.

When you want to talk about two past actions, one which happened before the other, remember to use the past perfect for the first action, and the past simple for the second.

用法總結

1. 過去完成式的結構是 「had」 + 動詞過去分詞。

2. 當一句話中有兩個在過去不同時段發生的動作時,先發生的動作使用過去完成式,而後發生的動作則常用一般過去式。

  • By the time I arrived at the airport, the plane had already left.
