01语态的基本概念
1. 主动语态:主语是动作的执行者(发出者)。
例句:We clean the room every day.
(主语“we”执行“clean”的动作)
2. 被动语态:主语是动作的承受者(主语是主动语态句子中的宾语)。
-例句:The room is cleaned every day.
(主语“the room”承受“被清洁”的动作)
02 被动语态的结构
被动语态的基本构成形式: 主语+助动词be+过去分词
初中阶段重点掌握一般现在时,一般过去时,一般将来时及含有情态动词的被动语态。被动语态的时态通过助动词be的变化来体现。这个助动词必须与主语的人称和数相一致。
常用时态的被动语态见下表:
时态 结构 例句
一般现在时 am/is /are +p.p. The lights are usually turned on at 6:30.
一般过去时 was/ were +p.p. Our school was built in 1998.
一般将来时 will be +p.p. The sports meeting will be held tomorrow.
含有情态动词 情态动词+be +p.p. This job must be done as soon as possible.
了解其他时态的被动语态
时态 结构 例句
现在完成时 has/have +been+过去分词 The bank has been built.
现在进行时 am/is/are +being+过去分词 The car is being repaired.
过去进行时 was/were +being+过去分词 The machine was being painted then.
03使用场景及注意事项
被动语态用法
1. 强调动作承受者(而非执行者):
- 主动:My mom made this cake.
- 被动:This cake was made by my mom.(强调蛋糕)
2. 动作执行者未知或不重要:
- The old bridge was built in 1950.(谁建的?不重要)
3. 避免主观表述(常见于说明文、科学文章):
- The results will be announced next week.
被动语态的特殊注意事项
1.及物动词才有被动语态,不及物动词(如 happen, appear, belong to)无被动形式:
- ❌ The accident was happened last night.
- ✅ The accident happened last night.
2. 主动表被动的情况(感官动词/系动词):
- The flowers smell sweet.(不用被动)
- The silk dress feels soft.
3. 双宾语的被动转换:
- 主动:He gave me a book.
- 被动1:A book was given to me.
- 被动2:I was given a book.
4.如主动句中宾语补足语是不带to的不定式,变成被动语态后要加to.
常见的结构有:make/let/hear/see/---sb do sth ----
→sb be made /let/heard/seen/---to do sth
如, I saw him go to the church. He was seen to go to the church.
04 答题技巧及即时训练
解题技巧
1. 判断是否需要被动语态:
找主语和动词的关系,主语是“承受者”则用被动。
2. 注意时态一致性:
主句是过去时,从句被动语态也要对应(如过去完成时)。
3. 注意固定搭配:
- be made of(可见原材料) / be made from(不可见原材料)
- be used to do(被用来做某事) / be used for doing(用途)
即时训练
1. The new library ______ (build) in our city next year.
2. Many trees ______ (plant) on the hill last spring.
3. When you ________ (give)a difficult task, try to continue with it and finish it.
4. More chances _____ (provide)for students to learn from each other if working in groups.
5.Children should ______ (educate)to be honest from a young age. 1
答案:1.will be built 2.were planted 3. are given 4. are provided 5. be educated
总结:
被动语态的核心是 “be动词 + 过去分词”,需结合时态灵活变化。做题时先判断主语是“执行者”还是“承受者”,再选择对应语态,注意时态和动词形式的匹配。
