篇一:小学英语语法【一般现在时】
一般现在时
用法:一般现在时表示经常的、习惯性的动作或存在的状态。
其用法可概括为:
①表示事物或人物的特征、状态;
— I am a boy.
②表示经常性或习惯性的动作;
— I usually go to bed at 10 o'clock.
③表示客观现实和普遍真理;
— The Earth goes around the Sun.
④表示一个按规定、计划或安排要发生的动作;
— The bus arrives at 7 in the morning.
构成:一般现在时的构成主要有两种形式
(1)be型:句子的谓语动词只有be(am,is或are)
例子:①肯定句— She is a teacher.
②否定句— She is not(isn't) a teacher.
③一般疑问句— Is she a teacher?
④肯定回答— Yes,she — No,she is not(isn't).
(2)实义动词型:句中的谓语动词为实义动词(也叫行为动词)
例子:①肯定句中,只出现实义动词:I get up in the morning.
②否定句中,要在实义动词前面加do(does)+not,do(does)作助动词,本身无意义,常与not缩写成don't(doesn't):I don't like vegetables. ③一般疑问句,要在句子开头加助动词Do(does):
— Do you like oranges?
— Yes,I do.
— No,I don't.
谓语动词(+s/+es)的变化规律:
①一般的动词,直接+s : say、read、know、work
②以s、x、ch、sh结尾的动词,+es:fix、kiss、catch、wash ③以辅音字母+y结尾的动词,把y→i,+es:fly、cry、study、try ④特殊变化:is→are、do→does
