在英語中，混合條件句（mixed conditionals）或錯綜條件句通過不同的時態，來談論與過去相反的情況所導致的現在可能發生的結果。這類句子的結構看似復雜，但如果理解了主句和從句之間的關系，就不難掌握它的用法。本集 “一分鐘英語” 視頻教你如何使用混合條件句。

文字稿

Hi! I'm Georgina from BBC Learning English. In today's lesson, we're looking at mixed conditionals.

We usually use mixed conditionals to talk about a past imaginary situation that has a present imaginary result.

For example: If I had eaten breakfast, I wouldn't be hungry now.

The first phrase uses the same structure as the third conditional – if + past perfect. This is because it is a past imaginary situation. It's not true. I didn't eat breakfast.

The second phrase uses the same structure as the second conditional – would + infinitive (no to). This is because it is a present imaginary result. It's not true. I am hungry because I didn't eat breakfast.

Don't forget to put the comma in after the 'if' clause.

Bye for now!

用法總結

混合條件句的前半部分結構為 “if + 過去完成時”，用來提出與過去事實相反或不符的情況；后半部分結構為 “would + 動詞原形”，引出若之前提出的假象條件成立，現在可能發生的結果。注意，“if” 從句在前時，從句后加逗號；“if” 從句在后時，不加逗號。

• If I had eaten breakfast, I wouldn't be hungry now. 
  （實際上之前沒有吃早飯，所以現在很餓）
• If he had studied harder, he would have a better job.   
  （實際上之前沒有努力學習，所以現在的工作一般）
• She wouldn't be late for the meeting if it hadn't been raining so hard.
  （實際上之前雨很大，所以沒能按時到達）
