行为动词的一般现在时及相应练习

行为动词一般现在时的变化

我们这里所说的行为动词,指的是除be动词、情态动词和助动词之外的全部动词。行为动词为数众多,主语为第三人称单数he, she, it 时,词形有变化。当主语是第三人称单数时，行为动词的一般现在时通常有三种变化：

1、多数在动词后加s

play—play s like—like s read-read s sing-sing s dance-dance s cook- cook s look- look s

2、以s，x，sh，ch，o结尾的动词加es

go—go es wash—wash es watch-watch es catch-catch es

do- do es

3、以辅音字母加y结尾，把y改i再加es

fly—fl ies study—stud ies try-tr ies

(这种变化与名词的单数变复数有点相像)

那么，什么情况下用行为动词的一般现在时呢？

当这个动作经常发生或表示习惯性的动作时，通常用一般现在时，它经常与表示频度的时间状语连用，如，当句子中有every day every year ,on Sunday, in the morning ,often, sometimes, usually, at one o’clock等词时，用一般现在时。

例句：He get s up at 6 o’clock.

She usually watch es TV in the evening.

Sometimes he go es to school by car.

Tom often fl ies a kite on Sunday.

只有第三人称单数动词才要变，其他人称（I, you ,we ,they）则用动词的原形。

一般现在时的用法及练习题(带答案)

一般现在时的用法及练习题 定义:一般现在时表示现在经常反复发生的动作、存在的状态或习惯性的动作的时态。 构成：一般现在时用行为动词的原形，但第三人称单数作主语时，动词的词尾要加-S。（一般的动词词尾+S。以sh/ch/s/x结尾的词+es.以辅音字母Y结尾的把Y变成i，+es。辅音字母+o结尾的+es.) 形式:主语+动词原形+宾语 用法：1.表示经常的或习惯性的动作，常与表示频度的时间状语连用。 2.表示主语具备的性格、能力和特征。 3.表示现在的状态。 4.表示客观事实和普遍真理。 5.在时间状语从句和条件状语从句中，常用一般现在时代替将来时。 6.表示预先计划或安排好的行为。 7.小说故事用一般现在时代替一般过去时。 8.有些表示状态和感觉的动词表示现在发生的具体行为时，只用一般现在时，而不用进行时态。 9.表示现在发生的具体动作或存在的状态 一般现在时的用法： 1) 经常性或习惯性的动作，常与表示频度的时间状语连用。 时间状语： always,usually,regularly, every morning/night/evening/day/week,often, sometimes, occasionally, from time to time, twice a week, rarely, seldom, once a month hardly ever, never. I leave home for school at 7 every morning. 2) 客观真理，客观存在，科学事实。 The earth moves around the sun. Shanghai lies in the east of China. 3) 表示格言或警句中。 Pride goes before a fall. 骄者必败。 ☆注意★：此用法如果出现在宾语从句中，即使主句是过去时，从句谓语也要用一般现在时。 例：Columbus proved that the earth is round.. 4) 现在时刻的状态、能力、性格、个性。 I don't want so much. Ann Wang writes good English but does not speak well. 比较：Now I put the sugar in the cup. I am doing my homework now. 第一句用一般现在时，用于操作演示或指导说明的示范性动作，表示言行的瞬间动作。再如：Now watch me, I switch on the current and stand back. 第二句中的now是进行时的标志，表示正在进行的动作的客观状况，所以后句用一般现在时。

2. 如果主语是we（我们），you （你，你们）, they （他们，它们，她们）或名词复数（两个以上的人或物）时，be动词必须用are。如：Are you twelve? 你是十二岁吗？ Tom and Lily are good friends. 汤姆和莉莉是好朋友。 They are at school. 他们在学校。 are与主语还可缩写。

如： We are= We're， They are =They're, You are = You're。而are与 not可缩写成aren't。如：They aren't students. 他们不是学生。 3. 如果主语是单数名词、不可数名词或单数第三人称代词（he, she, it）时，be动词用is。如:My mother is a teacher. 我的妈妈是一名老师。 He is a student. 他是一名学生。 is也可与主语缩写,

如: He is = He's, My mother is = My mother's 等。但是This is不可缩写。而is与not可缩写成 isn't。如:This isn't a book. 这不是一本书。 4. 句中含有be动词的陈述句变一般疑问句。把be动词提到句首，be动词要变大写。注意第一人称变第二人称。回答时用yes或no表示，结构：Yes, 主语+be动词，No，主语+be动词+not。如：It is a book. 变为：

A. are eating B. eat C. will eat D. have eaten 【答案】 B 【解析】【分析】句意：只要你少吃肉多吃蔬菜，你就会比以前更健康。as long as引导条件状语从句，时态是主将从现，故此处是一般现在时，故选B。 【点评】考查时态，注意as long as引导条件状语从句，时态是主将从现的用法。 2．She _____ out alone at night. A. dare not to go B. dares not go C. doesn't dare to go D. doesn't dares go 【答案】 C 【解析】【分析】句意：晚上她不敢一个人出去。dare可以作情态动词也可以作行为动词，作情态动词时，后面直接跟动词原形，没有人称与数的变化，构成否定时直接在dare 后加not，作行为动词时后跟动词不定式，构成否定需要助动词，故答案是C。 【点评】考查dare的用法，注意dare做情态动词和行为动词的用法上的区别。 3．The children will climb the mountain if it________ tomorrow. A. won't rain B. didn't rain C. isn't raining D. doesn't rain 【答案】 D 【解析】【分析】句意：如果明天不下雨，孩子们会去爬山。if 引导的条件状语从句遵循主将从现的原则，主句用一般将来时，从句用一般现在时，从句是一个否定句，含有实义动词rain的否定句，要借助助动词don't/doesn't构成，主语是it，助动词用doesn't，故选D。 【点评】考查if引导的条件状语的时态。注意句子涉及到if引导的条件状语从句的用法。 4．Not only Li Ming but also his parents ______ in Canada now.

If he , I'll call you at once.
