总结 初级经济法重点总结下载党员个人总结TXt高中句型全总结.doc高中句型全总结.doc理论力学知识点总结pdf 如下：???【变化规律】：????①动词三单现在式，一般词尾加s。????②s,x,ch,sh,o在词尾，直接加上es。????③“辅音字母+y”来结尾，变y为i是正规，es后边紧跟随，study→studies看明白。????④“元音字母+y”来结尾，直接加s,play--plays看明白。难点三：一般现在时疑问句和否定句的变法不清晰。孩子难于掌握，可归纳成三步法。【顺口溜】：一找，二添，三注意。?变疑问句：???一找：即找到be?动词am,is,are，把它放句首。???二添：即在找不到be?动词时，需要在句子首位添助动词do?或does。三注意：即注意一二人称互变，注意some?时要变为any。如果主语是三单就添does，注意在添了助动词后，句子中的实义动词要恢复原形。??变否定句：???一找：即找be?动词am,is,are，找到其中一个后在be?动词后加not，???二添：即是在找不到be?动词时,?在主谓之间添don’t?或doesn’t???三注意：是在添了don’t?或doesn’t?之后，实义动词要恢复原形。?难点四：一般现在时的基本用法不熟悉。很多学生虽然对一般现在时有了一定的认识，但对于它的几种用法始终是盲目的。对于这几种基本的用法很多学生在心中没有一个完整的概念。但可用歌诀这样描述：关于一般现在时，学生还要记住一句非常重要的话，即“时时心中有数”，学英语必须时时刻刻注意单复数和时态的变化。如果每一个学生能够巧妙记住以上几点，攻克四大难关，现在的难关也将变成“过去式。1.My?mother?________(work)?in?a?primary?school?and?I?_________?(study)?in?the?same?school.?2.I?________?(have)?a?bike?and?Ben?________?(have)?a?bike,?too.?3.?My?sister?________?(be)?a?pupil.?She?____________?(study)?very?hard.?4.?Who?___________?(cook)?breakfast?for?your?family??5.?My?father?is?a?teacher.?He?______________?(teach)?Chinese?in?a?primary?school二、一般过去时?要点一：概念要清晰????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。如：lastyear,yesterday，lastweek,in1980,twodaysago,amomentago等连用；也可表示过去经常反复发生的动作，常和often,always等频率副词连用。????例如：??①Isawhiminthestreetyesterday.昨天我在街上看见他了。??②LiMeialwayswenttoschoolonfootlastyear.去年李梅总是步行上学。要点二：4大句型要掌握1.Be动词在一般过去时中的变化：am和is在一般过去时中变为was。（wasnot=wasn’t）are在一般过去时中变为were。（werenot=weren’t）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。2.行为动词在一般过去时中的变化肯定句结构为：主语+动词的过去式+其它。否定句结构为：主语+didnot(didn’t)+动词原形+其它。一般过去时的一般疑问句的构成：Did+主语＋动词原形＋其它？特殊疑问句的构成：疑问词＋did+主语＋动词原形＋其它？?要点三：4大用法请牢记A带有确定的时间状语B表示过去连续发生的动作C表示过去一段时间内经常或反复的动作D强调已经终止的习惯要用usedto要点四：动词的过去式的变法和发音是难点。????一般过去时中最难掌握的就是“动词过去式”了，大部分学生对过去时的用法和概念都可以达到清晰的认识，但是在动词的变形上却难以把握。动词过去式的变法总结如下：(一)规则动词的4大变法。??1.一般情况加ed。look→looked??2.以不发音e结尾直接加-d。live→lived??3.以“辅音字母+y”结尾的动词，改y为i,加–ed，study→studied。??4.以重读闭音节（即辅音＋元音＋辅音）或r音节结尾，末尾只有一个辅音字母的动词，要先双写这个辅音字母加–ed。stop→stopped动词的变形除了掌握它的一般规则外更重要的是需要同学们在平时的学习中多积累，多记忆那些不规则动词，这样一般过去时的学习才会达到更好的效果。(二)动词过去式的发音????1.ed加在清辅音后面读/t/。looked????2.ed加在浊辅音或元音结尾的，读/d/。lived/-d/????3.ed加在/t/或/d/后面，读/id/。wanted/-tid/visited/-tid/???要点五：顺口溜大盘点???【顺口溜】：???一般过去时并不难，表示过去动作、状态就要谈。　??动词要用过去式，时间状语句末站。????否定句很简单，didn’t站在动词原形前，其它部分不要变。????一般疑问句也好变，did放在句子首，主语、动词原形、其它部分依次走。?????特殊疑问句也简单，疑问词加一般疑问句就不烦。????最后一条请注意，动词过去式要牢记。【即时演练】1.?My?father?__________________?(not?stay)?at?home?yesterday.?He?_________?(go)?to?Guangzhou.?2.?_______?they?____________?(visit)?the?zoo?last?Sunday??3.?---Who?___________?(teach)?you?maths?last?year?---?Mr?Liu?___________?(do).?4.?---?When?________?you?____________(take)?these?photos???---I__________?(take)?them?last?week.?5?Last?Saturday?my?mother?_________?(go)?shopping?and?______________?(buy)?me?a?dress.?6.?---?When?________?your?brother?___________?(get)?here??---?He?________?(get)?here?two?days?ago.?7.?---?______?Mike?________?(play)?computer?gameslastnight??---?No,?he?_________?.He?___________?(go)?to?see?a?gilm.??--When?________?you?____________?(begin)?to?learn?English??--I?____________?(begin)?tolearn?English?three?years?ago.9.?Ididn't?know?you?___________?here.?10.?Ben?________________?(catch)?a?cold?yesterday.?三：现在进行时态一．概念：当表示现在正在进行的动作或正在发生的事。二．构成:be(am,is,are)+动词现在分词-ing形式肯定句：主语+be+现在分词V-ing(+其他)I’mreadingbooksnow.否定句：主语+be+not+动词-ing+其他.I’mnotreadingbooksnow..一般疑问句：Be+主语+动词-ing+其他？Areyoudoingyourhomeworknow?Yes,Iam.No,I’mnot.特殊疑问句：特殊疑问词+be+主语+动词-ing+其他？Whatareyoudoingnow?三.现在分词的构成：（1）一般在动词末尾直接加ing,（2）以不发音字母e结尾的动词，先去掉e,再加ing，如skate→skatingmake→makingdance→dancingwrite→writinghave→havingride→ridingcome→coming（3）以重读闭音节结尾的动词，中间只有一个元音字母，词尾只有一个辅音字母，应双写末尾的辅音字母，再加ing,如：puttingrunningbeginningstoppingswimmingshoppingjoggingsittinggettingforgettingletting四、时间标志——now，句前的look,listen【即时演练】?1.?Listen!?Who________________?(speak)?English?in?the?library??2.?She?________?(like)?music.?Now?she?_____________?(sing).?3.?Don't?___________?(run)?in?the?street.?注解：________________________________________________4.?_________?you?_______________?(go)?to?school?every?day??5.?Class?is?over.?The?pupils?____________________?(play)?games.?6.?It's?6:30.?I?___________________(get)?up.?7.?Look,?the?pupils?_______________?(have)?an?English?class.?8.?My?mother?___________________?(wash)?the?bowls?in?the?kitchen?now.?9.?He?__________?(like)?art?very?much.?He?________________?(draw)?a?horse?now.?10.?Let?the?children?go?away.?They?_____________________?(make)?noise?here.四、一般将来时一、定义：一般将来时表示将来某一时刻的动作或状态，或将来某一段时间内经常的动作或状态。常常和表示将来的时间状语连用。如：tomorrow（明天），nextweek（下周）；inthefuture（将来）等。一般将来时由助动词shall（第一人称），will（第二、三人称）动词原形构成。美国英语则不管什么人称，一律用will。二、构成及变化一般将来时常用的两种结构begoingto+动词原形:表示打算、准备做的事或即将发生或肯定要发生的事。shall／will+动词原形:表示将要发生的动作或情况，没有太多的
