小学英语四种时态及口诀一提到时态，就必然用到动词。
首先要明确两个概念：动词有五种形式，即：原形（形式），第三人称单数（形式），过去式（形式），现在分词（形式），过去分词（形式）。
小学阶段，句子有以下四种常见时态，即：一般现在时态；一般过去时态；一般将来时态；现在进行时态。
式，意思就是各种不同的形式，是对应着动词来说的；时态，意思就是表达各种不同的时间的事情，是对应着句子来说的。
式与时，先搞懂区别。
一、一般现在时态一般现在时用法口诀一般现在时，every, usually, often, sometimes.第一、二人称和复数，动词原形不变换。
除了I, you，复数外，动词后加s(es)别忘怀。
要变一般疑问句，be动词提前很容易。
若是没有be动词，Do和Does开头要注意。
否定句，很简单，not 在be 动词后面站。
若是没有be动词，do, does加not 要牢记。
请把这些规律记，一般现在时没问题。
一般现在时态，可能是两种意思。
第一，表示经常性的动作，常与often, sometimes, usually, every day, everyweek, every month, every year等表示频率的副词连用。
例如：He often goes swimming in summer.I usually go to work by bike.Sam visits China every year.第二，表示现在的状态。
如：My mother is a worker.There is a computer in our classroom.注意问题：be (am, is, are) 动词就是独立的谓语动词，一个句子中有了be(am, is, are) 就有了谓语动词了。
句子中不能同时出现两个谓语动词。
不少同学经常出这样的错误：The boy is often eats hamburgers.（错）应改为：The boy often eats hamburgers.二、现在进行时态正在进行时态口诀现在分词用途多，进行时态不用说。
它的构成很好记，动词后缀ing。
词尾若有哑音e，去e再加没问题。
一辅重读闭音节，这个字母要双写。
还有一点要注意，改y为ie再加ing。
现在进行时态，表示现在正在发生的动作。
结构是：am/is/are + 动词ing（现在分词）形式。
如：I’m writing a story.You/They/We are cleaning the classroom.He/She/It is having some food.三、一般将来时态一般将来时态用法一般将来时，将要发生事。
谓语不一般，will后加动原。
要变疑问句，will置主语前。
否定句，也不难，will后把not添。
一般将来时态，表示将要发生的事情。
结构是：am/is/are going to + 动词原形；或者是will + 动词原形。
will 通用于各种人称之后，不受人称和单/复数变化的影响。
如：I/We/You/You/He/She/It/They will have a walk after supper.I am/ We are/They are/ You are/ He/She/It is going to have a walk after supper.四、一般过去时态一般过去式之歌过去式构成有方法，一般词尾加ed。
如果词尾有个e，直接加d就可以。
辅音字母y在尾，变y为i加ed。
“一辅重闭”作尾巴，双写之后ed加。
标准过去式加ed，少量不规则分别记。
am和is对was，are要变were没问题。
have和has用had，do和does变did。
小学英语动词过去式顺口溜过去式很简单，只要你能这样记。
前提必须是动词，不规则变化先记牢。
再记规则两三条，结尾有e只加d. live变成lived.y结尾也不难，辅音字母嫌他烦，把y换成i才愿加ed. Carry变成carried。
目前双写只有俩，hop过去hopped, stop要变stopped。
其他动词很随和，带上ed就能一起回过去。
动词过去式不规则词(目前学过的)：am—was is—was are—weredo—did does—did have—had has—hadgo—went buy—bought fall—fell一般过去时态，也有两种意思。
第一，表示过去发生的动作，经常与明确的表示过去的时间连用，如：last week, yesterday, the day before yesterday,last night, last year, last weekend 等。
如：The family had a picnic in the park last weekend.第二，表示过去的状态。
如：There was a small pond in the school before.Mary was a teacher two years ago.注意问题：be (was, were) 是独立的谓语动词，它不能与行为动词的过去式同时使用。
同学们经常出这样的错误：It was rained yesterday. （错）应改为；It rained yesterday.The ducks were ate our picnic. （错）应改为：The ducks ate our picnic.过去式动词不存在第三人称单数的问题。
也就是说，一般过去时态的句子中，无论主语是什么人称，单数还是复数，过去式动词都不能加s/es.可见：动词原形使用于一般现在时态的第一人称单、复数之后；第二人称但、复数之后；第三人称复数之后；还使用于一般将来时态。
动词过去式使用于一般过去时态各种人称之后。
动词第三人称单数使用于一般现在时态的第三人称单数之后。
现在分词使用于现在进行时态中。
do/does/did 这三个助动词也是经常用错的单词。
他们都是助动词，意思就是说他们是帮助行为动词的单词。
do/does 用于一般现在时态，did用于一般过去时态。
问句（一般疑问句/特殊疑问句/选择疑问句等）和否定句中使用它们。
do/does/did 总是与动词的原形连用。
句子的时态通过主动词体现出来。
如：Do you often go swimming? No, I don’t often go swimming.Does he like apples? No, he doesn’t like apples.Did they go to the supermarket last Sunday? No, they didn’t.小学六年级上册英语时态专项习题look , read and write1. There ( is / are ) some bananas ( on / near ) the table .2. There ( is / are ) a football (in / under ) the bed .3.
