05
动词不定式与其他非谓语动词比较
与动名词比较
动词不定式和动名词在句子中都可以充当主语、宾语等成分,但它们的意义和用法 有所不同。
动词不定式表示具体的、一次性的动作,而动名词则表示抽象的、习பைடு நூலகம்性的动作。
在某些情况下,动词不定式和动名词可以互换使用,但表达的含义可能有所不同。
与现在分词比较
动词不定式和现在分词都可以表示主 动的动作,但它们的时态和语态有所 不同。
在某些情况下,动词不定式和现在分 词可以互换使用,但需要根据具体语 境来判断。
动词不定式不受时态限制,可以表示 过去、现在或将来的动作,而现在分 词则通常表示正在进行的动作。
与过去分词比较
动词不定式和过去分词都可以表示被动的动作,但它们的用法和意义有 所不同。
动词不定式表示被动的动作时,需要使用助动词be的适当形式,而过去 分词则可以直接表示被动的动作。
03
动词不定式在句子中作用
作主语
01
动词不定式作主语时,谓语动词 用单数形式。
02
常用it作形式主语,把真正的主语 动词不定式置于句后。
作宾语

动词不定式与名词等构成复合宾语时 ,通常要用it作形式宾语,而把真正的 宾语动词不定式置于句后。

“I enjoy to listen to music”。
逻辑主语问题
要点一
不定式逻辑主语与句子主语不一 致
动词不定式的逻辑主语应与句子主语保持一致。例如,正 确的表达是“It is important for you to study hard”, 而不是“It is important for him to study hard”。

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

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。

4.为了不错过第一趟火车,他走得很早。
•He left very early __in__o_rd_e_r_n_o_t _to__/s_o_a_s_n_o_t tmoiss the rain.
▲但是在下列情况表示肯定意义:
“too...to”结构之前带有but, only, all, never, not时,是强调肯定的 表示法,译作“非常……、十分……、实在……、真是太……”等;
“too...to”结构中带有表示某种心情或描绘性的形容词或副词,如 ready, eager, satisfied, kind, willing, easy, anxious等加不定式结合成一

个不可分割的状态、态度、倾向或心情等,并且其后的不定式不是 说明too的具体内容,而是修饰形容词,故不定式不再表结果。如: We are only too happy to live in China. 生活在中国,我们太幸福了。
They are all too satisfied to go and do this work. 他们很乐意地去做这 项工作。

二、结构上的特点 不定式用作目的状语有两个可能的位 置,一是在句首,二是在句末。一般 说来,用于句首属于强调性用法,即 强调动词的目的。比较:
To get 100 points, we must study hard.

一、句意上的特点
不定式用作目的状语时,其句意特点很明显, 通常在译成中文时可用“为了”来表示。如:
To get 100 points, we must work hard. 有时即使没有直接翻译出“为了”,但其中 包含了类似意思,如“目的是”“目的是为 了”等。 1. We made a fire to keep us warm.我们生 火的目的是为了保暖。to keep us warm 就是 make a fire 的目的。
• 2. Let's go to the shop to buy some bread.让我们去超市买一些面包。其 中,to buy some bread就是go to the shop 的目的。
• 3. Last night I went to Green Street to see my uncle.昨晚我去格林大酒 店看了我叔叔。to see my ueet 的目的。
