初中动词不定式完整ppt课件
但有的动词（如：need, want, require等）后面接动名词或动 词不定式作宾语均可。
在It + be + 形容词（easy, difficult, expensive等） + 不 定式句型中，动词不定式常用it 作形式宾语，而将真正的宾语 放到句子后面。
作定语
动词不定式作定语时，要放在被修饰的名词之后，表示与这个名词有逻辑上的动宾 关系，即不定式动词可以修饰的名词应是它的表语或宾语。
误用动词不定式的时态和语态
动词不定式的时态和语态需要根据句子的语境和上下文进行判断，但在 实际使用中，学生往往容易忽略这一点，导致时态和语态的错误使用。
注意事项
注意动词不定式的正确性
在使用动词不定式时，要确保其形式 的正确性，包括时态、语态、逻辑主 语等方面。
注意上下文语境
多练习、多积累
掌握动词不定式的用法需要大量的练 习和积累，因此学生应该多做相关练 习，多阅读相关材料，以便更好地掌 握这一语法点。
例如
They were watching TV at this time yesterday.（昨天这 个时候他们正在看电视）
语态的转换
1 2
主动语态 表示主语是动作的执行者
被动语态 表示主语是动作的承受者
3
动词不定式的语态转换
将主动语态的不定式改为被动语态的不定式，一 般在不定式前加to be，并将不定式的逻辑主语 作为被动语态的主语
04
动词不定式的省略和倒装
省略情况
当动词不定式在句子中作宾语补足语，表示的是一次性 的具体动作，且句子的主语和不定式的逻辑主语一致时， 可以省略to。
当动词不定式中的动词是be、have、助动词或情态动 词时，可以省略to。
