第四章:时态

第一节

一、动词的时态

作谓语的动词发生变化来表示行为,状态发生的时间及进行的情况的各种形式称为时态。英语有两种语态:主动语态和被动语态。时态和语态是英语语法的重要组成部分,也是考试必考的内容之一。从是否跟宾语的角度来看,英语动词可以分为两种,即不及物动词和及物动词。不及物动词没有被动语态。及物动词有两种语态:主动语态和被动语态。任何一个及物动词不是使用主动语态,就是使用被动语态,没有语态的及物动词是不存的。时态测试实际上也同时测试语态。

初中英语语法精讲动词不定式用法(教案)

动词不定式用法 动词不定式没有人称和数的变化,在句中不能独立作谓语。但动词不定式具有名词、形容词和副词特征,在句中可以作主语、宾语、宾语补足语、定语、表语和状语等多种成分。另外,动词不定式具有动词特点,可以有自己的宾语和状语,组成动词不定式短语。动词不定式的肯定形式是to+do;其否定形式是not to+do。 下面以动词不定式在句中的作用来予以详细说明。 1.作主语 可以直接作主语。如:To see is to believe. 但在英语中,常用it作形式主语,真正的主语即动词不定式放在后面。如: It's wrong to play tricks on other people. It's our duty to keep our environment clean and tidy. 点击规律:动词不定式在句中作主语时,常放在It is +adj +(for sb.)+(not)to do sth句型中,表示说话人对客观事件的决断,意为:做…..是……的,it仅作形式主语,真正的主语是to do sth It is very interesting to read.读书是有趣的 It is useful to read.看书是有用的 It is healthy to run every day.每天跑步是健康的 It is a little difficulty for me to work out this question.解出这道题对我来说有点难 It is bad not to finish homework.不完成作业是糟糕的 It is bad to be late for school.迟到是糟糕的 It is+adj+of sb +(not)to do sth该句型通常表示说话人对客观事件的惊讶、兴奋、懊悔、难过等感叹情绪,与It is +adj +(for sb.)+(not)to do sth的意义不同。 It is very kind of you to tell me the truth.你能告诉我事实,真是太好了 It is stupid of him to do such a silly thing.他做那件傻事,真是太笨了 It is very clever of you to work out this question. 你能解出这道题目,真是太聪明了 It is very wise of you to read this novel. 你看这本小说,真是太明智了 这个句型中用介词of而不是for的原因是这里的形容词是用来形容人的品质性格的。 类似的词有:careless,careful,clever,considerate,foolish,good,impolite,kind,naughty,nice,silly,stupid,friendly 因此区分是用It is +adj +(for sb.)+(not)to do sth还是It is+adj+of sb +(not)to do sth,要
