The house will be painted next week.(这座房子下周将会被涂漆。)
4. 现在进行时:am/is/are being + 过去分词
The cake is being baked in the oven.(蛋糕正在烤箱里烘焙。)
二、被动语态的用法
被动语态主要用于以下情况:
1. 强调动作的承受者,而不是执行者。
The window was broken by the strong wind.(窗户被大风打破了。)
2. 当我们不知道或不关心动作的执行者时。
The concert tickets were sold out in just a few hours.(音乐会门票在几小时内就卖光了。)
3. 在科学、新闻报道等中使用。
The new discovery has been widely reported.(这一新发现已经广泛报道。)
三、被动语态的变化规则
被动语态的变化规则主要包括时态和人称的变化。例如:
1. 时态的变化
- 一般现在时:am/is/are + 过去分词
- 一般过去时:was/were + 过去分词
- 一般将来时:will be + 过去分词
- 现在进行时:am/is/are being + 过去分词
2. 人称的变化
- 第一人称:am/are + 过去分词
- 第二人称:are + 过去分词
- 第三人称:is/are + 过去分词
以上就是九年级英语中被动语态的相关知识点讲解。希望同学们通过学习和练习,能够掌握被动语态的用法和变化规则,提高自己的英语表达能力。
