动词加ing的变化规则

1．一般情况下，直接加ing，如：cook-cooking

2．以不发音的e结尾，去e加ing，如：make-making, taste-tasting ,take-taking 3．如果末尾是一个元音字母和一个辅音字母，双写末尾的辅音字母，再加ing，如：run-running, stop-stopping ,swim-swimming, get-getting A、构成形式：主语+be动词+动词的ing形式+其他。

B、判断依据：句中往往有now、look、listen等词。注意：千万不要忘了一定得有be动词 C、句型变换：练一练：

A、用所给的动词的正确形式填空。

1) The boy ______ ______ ( draw ) a picture now. 2) What______you ______ ( do ) now?

3) Listen. Some girls ______ ______ ( sing ) in the classroom. 4) My mother ______ ______ ( cook ) some nice food now. 5) Look. They ______ ______ ( have ) an English lesson. 6) They ______ ______ ( not water ) the flowers now.

3) 她正在公园里散步吗？是的。--- _____ she______a walk in the park? ---Yes, she______.

4) Jack正在哪读书？在他书房。

--- ______ ______ Jack ______ the book now? ---He is______ ___ ___ ______.

2、一般过去时

1．一般过去时表示过去某个时间发生的动作或存在的状态，常和表示过去的时间状语连用。一般过去时也表示过去经常或反复发生的动作。如：yesterday ,last( weekend ,month ,year„) be used to 2．Be动词在一般过去时中的变化： ⑴am 和is在一般过去时中变为was。（was not=wasn’t） ⑵are在一般过去时中变为were。（were not=weren’t）

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?

七、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

3．末尾只有一个元音字母和一个辅音字母的重读闭音节，应双写末尾的辅音字母，再加-ed，

如：stop-stopped

4．以“辅音字母+y”结尾的，变y为i，再加-ed，如：study-studied 5．不规则动词过去式：

am,is-was, are-were, do-did, see-saw, say-said, give-gave, get-got, go-went, come-came, have-had, eat-ate, take-took, run-ran,

sing-sang, put-put, make-made, read-read, write-wrote, draw-drew, drink-drank, fly-flew, ride-rode, speak-spoke, sweep-swept,

swim-swam, sit-sat, teach-taught , feel -felt , buy-bought, leave-left A、构成形式：主语+动词的过去式+其他。注意：没有be动词的否定句和疑问句中，用didn’t否定和用did提问后，动词一定要用原形

B、判断依据：（1）be动词是was、were；（2）动词加ed；（3）有表示过去的时间状语，现在学过的常用的表示过去的时间状语有：just now，a moment，yesterday，last week，last night，last weekend，last year，last month，three days ago，two weeks ago，five years ago„ 3、一般将来时

1. 概念：表示将要发生的动作或存在的状态及打算、计划或准备做某事。句中一般有以下时间状语：tomorrow, next day(week, month, year„),soon, the day after tomorrow（后天）this morning , this afternoon , this evening等。

2.基本结构：①be going to + do；She is going to visit his grandparents next weekend .

Amy is going to climb mountains tomorrow.

②will+ do. He will go shopping this afternoon. He will go to shanghai next month .

3.否定句：在be动词（am, is, are）l后加not或情态动词will后加not成won’t。

A、构成形式：（1）主语+be going to+动词原形+其他。（2）主语+will+动词原形+其他。

B、判断依据：一个句子中既有be动词，又有going、to和动词，且动词用的是原形，句中

往往有tomorrow、soon、next week等词。 C、句型变换：肯定句

否定句
