英语语法知识复习一、词类：（一）动词行为动词、be动词、情态动词。

（1）行为动词原形、+s/es、+ed、+ing（2）be动词a、Am--was Is --was Are--were 口诀：我用am, 你用are, is用在他她它，所有复数全用are。

b、肯定和否定句I am (not) from London. He /She is(not) a teacher. My hair is(not) long. Her eyes are(not) small. c、一般疑问句A m I …? Yes, you are. No, you aren’t. Are you/they…? Yes,we/ they are. No,we/ they aren’t. Is the cat fat? Yes, it is. No, it isn’t.is、am、are为一类，一般用于一般现在时、现在进行时和一般将来时中。

was和were为另一类，一般用于一般过去时。

（3）情态动词情态动词是一种本身有一定的词义,表示说话人的情绪,态度或语气的动词,但不能单独作谓语, 只能和其他动词原形构成谓语。

can、must、should、may、will。

情态动词后动词总是用原形。

（不受其他任何条件影响）1. I / He / She / They can sing. May I come in? I must go now.2. You should be quiet in the library.3. You’ll be good friends.（二）名词这里强调两点：不可数名词都默认为单数，所以总是用is或者was。

单数名词表示一个可数事物，复数名词表示两个或两个以上的可数事物。

一、可数名词与不可数名词的区别普通名词所表示的人或事物是可以按个数计算的，这类名词叫可数名词。

可数名词分为个体名词(表示某类人或事物中的个体，如worker, farmer, desk, factory等)和集体名词(表示作为一个整体来看的一群人或一些事物，如people,family 等)。

小学英语语法Be动词的用法总结及练习一、Be动词的用法口诀:be动词am\is\are,我(I)用am，你(you)用are，is连着他(he)，她(she)，它(it)；单数名词用is，复数名词全用are。

我们（we）你们（you）和他们（they）都用are;过去式am\is变was,are变 were;变疑问，往前提，句末问号莫丢弃。

变否定，更容易，be后not莫忘记。

疑问否定任你变，句首大写莫迟疑。
