八年级人教版七单元知识点
八年级人教版七单元知识点人教版八年级下册第七单元知识点人教版八年级下册的第七单元是有关动词时态和语态的学习。
本单元内容主要分为以下几个方面：一、动词的时态时态是动词的一个重要概念，表示动作发生的时间。
在英语中，主要有以下12个时态：一般现在时、现在进行时、一般过去时、过去进行时、将来时、将来进行时、现在完成时、过去完成时、将来完成时、过去将来时、过去完成进行时、将来完成进行时。
其中，一般现在时、一般过去时和将来时是最基本的时态。
我们可以通过以下例句来更好地理解各时态的用法：1. My sister watches TV every evening. （一般现在时）我妹妹每天晚上看电视。
2. They are playing basketball now. （现在进行时）他们正在打篮球。
3. He went to Beijing last week. （一般过去时）上周他去了北京。
4. She was studying when I called her. （过去进行时）我打电话的时候她正在学习。
5. We will visit the Great Wall tomorrow. （将来时）明天我们将要去参观长城。
6. By next year, we will have been studying English for five years. （将来完成时）到明年，我们学习英语就五年了。
二、动词的语态除了时态之外，还有一个重要的概念是语态，它表示一个动作或状态是主动的、被动的或使役的。
英语中一般有两种语态：主动语态和被动语态。
1. 主动语态主动语态是指主语是执行某事情的人或者物。
例如：I eat bread.我吃面包。
He sings the song.他唱这首歌。
2. 被动语态被动语态是指主语是接受某事情的人或者物。
与主动语态相比，被动语态中的谓语动词需要添加助动词be并且将动作承受者变成主语。
