⑶带有was或were的句子,其否定、疑问的变化和is, am, are一样,即否定句在was或were后加not,一般疑问句把was或were调到句首。 3.句中没有be动词的一般过去时的句子
否定句:didn’t +动词原形,如:Jim didn’t go home yesterday. 一般疑问句:在句首加did,句子中的动词过去式变回原形。
如:Did Jim go home yesterday? 特殊疑问句: ⑴疑问词+did+主语+动词原形?如: What did Jim do yesterday?
⑵疑问词当主语时:疑问词+动词过去式?如:Who went to home yesterday? 动词过去式变化规则:
1.一般在动词末尾加-ed,如:pull-pulled, cook-cooked 2.结尾是e加d,如:taste-tasted

(二)小升初英语词类:
动词、名词和形容词不太容易区分,如不能一眼看出,可用如下方法:
先用“一(量词)”(如:一个、一张等)和这个词连起来说,如说得通,一般认为是名词;说不通再用“很”去判断,就是把“很”和为个词连起来说,说得通一般就是形容词;都说不通就是动词。(目前我们学过的,以后可能不同)(另外一些很明显的,如人称代词、数词、情态动词等一下就可以知道) 1、动词
这里所说的动词是指各种动词总称,其中包括行为动词(就是我们平时总说的那种动词)、be动词、情态动词。 (1)行为动词
就是我们平时上课时说的动词,表示某一动作或行为。如:sweep、live等。 行为动词我们已学过它们的四种形式:
原形、+s/es、+ed、+ing,具体判断方法如下: ↗有,就加ing
读句子→读该单词→认识该单词→理解意思→看有无be动词 (若是be going to 就用原形) ↘没有,再看情态动词 ↗有,就用原形 ↗有,就加ed
↘没有,再看有无表示过去的时间状语 ↗是第三人称单数就加s或es ↘没有,再看主语
↘不是第三人称单数就用原形 (2)be动词
a、Am--was Is --was Are--were 口诀:我用am, 你用are, is用他她它,所有复数全用are。 b、肯定和否定句
I am (not) from London. He is(not) a teacher. She is(not) in the dining room.
My hair is(not) long. Her eyes are(not) small. c、一般疑问句
Am I a Chinese? Yes, you are. No, you aren’t. Are they American? Yes, they are. No, they aren’t. Is the cat fat? Yes, it is. No, it isn’t. 我们现在学过的be动词大致分两类: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。 判断步骤:
↗第一、三人称单数,就用was ↗有,再看人称
↘第二人称单数和所有复数,就用were 看有无表示过去的时间状语 ↗第一人称单数,就用am
↘没有,再看人称→第三人称单数,就有is ↘第二人称单数和所有复数,就用are 用am, is, are 填空
1. I ______ a boy. ______ you a boy? No, I _____ not. 2. The girl______ Jack's sister. 3. The dog _______ tall and fat.
4. The man with big eyes _______ a teacher. 5. ______ your brother in the classroom?
