一般现在时表示习惯性、经常性、反复性的动作或存在的状态。“习惯性、经常性、反复性”是一般现在时的三大特性，它不表示特定时间内发生的事。二、一般现在时的结构 时态的结构指的是动词的变化形式。一般现在时间有两种结构：1动词原形，用于主语为非第三人称时的情况；2为动词的第三人称单数形式，用于主语为第三人称时的情况。eg1.We often get up early in the morning.eg2.My father often gets up early in the morning.三、谈谈“主语为三单，其后动词 s 添”在一般现在时中，当主语为第三人称单数时，谓语动词要用第三人称单数形式。可以简单叙述为“主语为三单，其后动词 s 添”。何谓第三人称单数？用一句话概括就是“非你、非我、非复数”，如 he,she,it,my father,my mother,my sister,our English teacher,Tom,Mike,Liu Jia,China,my book,etc.Eg3.He sometimes goes to school by bike.Eg4.My father works in the hospital as a doctor.四、动词第三人称单数变化规则 动词第三人称变化的规则与可数名词复数变化的规则相同。规则一、一般在词尾加-s。如：looks,puts.reads,sees,skis 等。规则二、以-o,-s,-x,-sh,-ch 结尾的加-es。如：goes,does,misses,passes,mixes,fixes,pushes,wishes,watches,teaches,等。规则三、以辅音字母加 y 结尾的，变 y 为 i，再加-es。注意一定是辅音字母加 y 才变，若是元音字母加 y，则直接加-s。如：fly flies,try tries,fry fries,copy copies buy buys,enjoy enjoys,play plays,say says,pay pays 五、一般现在时的句子转换（1）当句子中有 be 动词或情态动词时，则把 be 动词或情态动词(can,could 等等)提到主语的前面变成一般疑问句;在 be 动词或情态动词后面加 not 变成否定句.例：陈述句：She is a student.一般疑问句 Is she a student?否定句 She is not a student.陈述句：I can swim.一般疑问句 Can you swim?否定句 I can not swim.（2）当句子中既没有 be 动词，也没有情态动词时，则在主语前加助动词 do(you,以及复数),does（单数 she,he,it）变成一般疑问句；在主语后谓语动词前加助动词 dont（I,you,以及复数),doesnt（单数 she,he,it）变成否定句，助动词后的动词要变成动词原形。例：陈述句：We get up at 7:00 every morning.一般疑问句Do you get up at 7:00 every morning?否定句We dont get up at 7:00 every morning.陈述句：She has a little brother.一般疑问句 Does she have a little brother?否定句 She doesnt have a little brother.六、练习巩固 用括号内动词的适当形式填空。1.We often_(play)in the playground.2.He _(get)up at six oclock.3._you_(brush)your teeth every morning?4.What_(do)he usually_(do)after school?5.Danny_(study)English,Chinese,Maths,Science and Art at school.6.Mike sometimes _(go)to the park with his sister.7._ Mike_(read)English every day?8.What time_his mother_(do)the housework?9.She _(go)to school from Monday to Friday.10.The child often _(watch)TV in the evening.Where is the egg?Teacher:Can you make a sentence with the word egg?Student:Yes.I ate a piece of cake yesterday.Teacher:Then where is the egg?Student:In the cake,Sir.一现在进行时态表示现在(说话瞬间)正在进行 或发生的动作。如:The students are listening to the teacher.He is watching TV now.现在进行时态还可以表示当前一段时间内的活动或现阶段正在进行的动作。如:We are working on a farm these days.I am writing a book this month.二.动词-ing 形式的构成 一般在动词原形后+ing go ask going asking 以不发音的e结尾的,去e,+ing write take close writing taking closing 重读闭音节以一个辅音字母结尾的，双写这一字母+ing get run swim put getting running swimming putting 注意:以”ie”结尾，要变“ie”为“y”,再加-ing.如：diedying(死）lielying(平躺）。三.常与现在进行时态连用的词:Now（现在）,listen（听）,look（看）,Be quiet.（安静）these days（这些天）,at the moment（此时，现在）,Its eight oclock.等。如:What are you doing now?Im reading now.四.现在进行时由 be(am/is/are)+动词-ing 形式构成。肯定式结构:主语+be+动词-ing 形式+其他.否定式结构:主语+be+not+动词-ing 形式+其他.一般疑问句结构:Be+主语+动词-ing 形式+其他？特殊疑问句结构:疑问词+be+主语+其他？一般疑问句回答:肯定回答:Yes,主语+be;否定回答:No,主语+be+not.五一些表示状态或情感的动词，如：want,have(有），think,like,love,hope，hate(恨)等没有现在进行时态。六一些表示位置移动的动词，如：come,go,arrive,get,reach,leave，fly，start 等常用现在进行时态表示将来的动作。e.g I know you are arriving next Sunday.I am coming,Mum.I am leaving next week.七动词现在分词变变变 （熟记）write writing take taking have having make making sit sitting shop shopping cut cutting stop stopping put putting get getting begin beginning swim swimming run running 八 现在进行时与一般现在时的区别：现在进行时是表示一个动作正在发生或进行。一般现在时表示现在的状态或经常的，习惯性的动作。Look!区别下面的两组句子：I do my homework every day.I am doing my homework now.He cleans his room every afternoon.He is cleaning his room now.九练习 I.单项选择()1.Dont turn on the TV.Grandma _now.A.Is sleeping B.will sleep C.slept D.sleeps()2.We want _ this book

classroom。（对划线部分提问)_ 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。2Be 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。（was not=wasnt）are 在一般过去时中变为 were。（were not=werent）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：didnt+动词原形，如：Jim went home yesterday.Jim didnt 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：Jim went home yesterday.Did Jim go home yesterday?特殊疑问句：疑问词+一般疑问句？如：Jim went home yesterday.Did Jim go home yesterday?What did Jim do 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
