非谓语动词的时态和语态
非谓语动词的时态和语态非谓语动词是指在句中不充当谓语成分，通常以动词原形或动词的其他非限定形式呈现的动词。
非谓语动词的时态和语态主要根据上下文确定，本文将详细介绍非谓语动词的时态和语态的使用。
一、非谓语动词的时态1. 不定式：不定式作为非谓语动词形式，不受时态的限制，通常表示动作发生在谓语动词所表示的动作之前。
例如：- To understand English well, one must practice every day.（为了能够很好地理解英语，人们必须每天练习。
）- I forgot to buy milk on the way home.（我从没想到，在回家的路上忘了买牛奶。
）2. 现在分词：现在分词作为非谓语动词形式，通常表示与谓语动词所表示的动作同时或一般性的动作。
例如：- Walking along the street, I noticed a small cafe.（在街上走的时候，我注意到了一家小咖啡馆。
）- The teacher was talking to the students, explaining the new lesson.（老师正在和学生们谈话，解释新的课程。
）3. 过去分词：过去分词作为非谓语动词形式，通常表示在谓语动词所表示的动作之前已经完成的动作。
例如：- Having finished his homework, the boy went out to play.（孩子做完作业后，出去玩了。
）- The injured man was taken to the hospital, accompanied by his family.（受伤的人被他的家人陪同着送到了医院。
）二、非谓语动词的语态非谓语动词的语态主要包括主动语态和被动语态，具体如下：1. 不定式的语态：不定式的语态通常与主句的语态保持一致。
例如：- She wants to be promoted.（她想要升职。
动词不定式的时态与语态
动词不定式的时态与语态动词不定式是动词的一种非谓语形式，在句中不能单独作谓语。
但动词不定式仍具有动词的性质，它不但可以有自己的宾语和状语，从而构成动词不定式短语，它还可以有时态和语态的变化，即一般式、进行式、完成式和被动式。
1.动词不定式的一般式动词不定式的一般式表示的动作通常与主要谓语的动作同时或几乎同时发生，或是在它之后发生。
I happened to be there. 我当时刚好在那里。
（同时发生）To catch the plane, you'd better hurry to the air port by taxi. 为了赶飞机，你最好赶紧乘出租车去机场。
（to catch the train发生在hurry to the station之后）2.不定式的进行式动词不定式的进行式表示的动作与谓语动词所表示的动作同时发生。
Tom pretended to be reading the newspaper when his father came into the room. 他父亲走进房间时，汤姆装着在读报纸。
My brain doesn’t seem to be working well today.我的脑子今天似乎不大好使。

4.动词不定式的完成进行式动词不定式的完成进行式表示的动作在谓语动词所表示的动作之前一直在进行。
动词不定式
C-不定式的概念、作用语法梳理不定式一、概念：在语法中，动词不定式是指动词的一种不带词形变化从而不指示人称、数量、时态的形式。
形式为：to+动词原形+其他。
之所以被叫做不定式，是因为动词不被限定，或者说不被词形变化所局限。
不定式属于非谓语动词。
不定式的时态有：一般式、进行式、完成式和完成进行式。
二、不定式的作用1、作主语。
不定式作主语时，谓语用单数。
往往用it作形式主语，把不定式放在谓语后面。
如：It took us two hours to finish the job.It is impossible for us to get there on time.It is very kind of you to help us.注意：（1）其他系动词如look, appear等也可用于此句型。
（2）当不定式作主语的句子中又有一个不定式作表语时，不能用It is …to…的句型。
试比较：It is to negate(取消，否定）my own idea to believe him.（错）To believe him is to negate my own idea .（对）（3）It is+ adj. of / for sb. to do sth. 结构中，当不定式的逻辑主语和前面的形容词可以构成系表结构时，用of, 否则用for.2、作宾语（1）动词+不定式。
如：He managed to escape from the fire.I find it hard to get along with him.（it 作形式宾语）（2）动词+疑问词+to , “特殊疑问句+不定式”相当于名词，作宾语。
如：I don’t know what to do next/ how to do it next.I can’t decide when to go there.注意：不定式短语作宾语时，如果还带有宾语补足语，往往把不定式短语放在宾语补足语之后，用it 作形式宾语。
动词不定式的用法
I am the only man to hear the news.
(6)作状语 ①作原因状语 结构：主语+be+adj.+to do (形容词多为表示情绪或状态的形容 词)
I am sorry to hear you were ill.
We hurried to the station only to be told that the train had left. 我们急匆匆 赶到车站，结果被告知火车已经开走了。
④作评论性状语 to be honest, to tell the truth, to cut a long story short, to put it another way
Mary seems to be thinking deeply.
玛丽似乎在沉思。
(4)不定式的被动形式 当动词不定式的逻辑主语是不定
式所表示的动作的承受者时，一般 要用其被动形式。
The radio needs to be repaired. 收音机需要修理。
2.不定式的句法功能 不定式相当于名词、形容词、副
to be done
完成式
to have done
to have been done
进行式
to be doing
——
完成进行式 to have been doing
——
注意：否定形式是在不定式符号to前加not
(1) 不定式的一般式 表示的动作通常时间性不强，
与谓语动词表示的动作没有时间 先后顺序。
(3)作表语 可以表示主语的具体内容、目的等。
My wish is to have a job in an office. 我的愿望是有一份在办公室里的工作。
