1、现在进行时,定义现在进行时的定义:现在进行时表示现在或当前一段时间正在进行的动作。也可以表示有计划的未来,也就是用现在进行时表示将来。,一、构成方法现在进行时由 am/is/are 加现在分词构成。,二、用法说明1)表示此时此刻或现阶段正在进行的动作。如:Theyre having a meeting.Im studying at an evening school.2)表示计划或安排好了的将来动作,常与一个表示将来的时间状语连用。如:Mike is coming home on Thursday.Theyre having a party next week.注:表示安排将要做的事,人作主语
2、宜用现在进行时,事物作主语,宜用一般现在时。试比较:Im not going out this evening.The concert starts at 7:30.,3)现在进行时与always,often,forever等连用表示赞扬、厌烦等语气。如:Youre always interrupting me!你老打断我的话!(抱怨)My father is always losing his car keys.我爸老丢车钥匙。(不满)Shes always helping people.她老是帮助别人。(赞扬)4)现在进行时在时间和条件状语从句中,代替过去将来时。如:He promised
3、 to buy me a computer if he got a raise.注意:像 be,think,understand,love,have,own,see,hear,find,belong to 等静态动词通常不用于进行时。,三现在进行时的肯定肯定句、否定句、疑问句形式:,1)现在进行时的肯定句主语+be+现在分词+eg.I am watching TV.eg.She is washing the dishes.eg.They are playing games.2)现在进行时的否定句句型 主语+相应be动词+not+现在分词+eg.He isnt watching TV.I am
4、not cooking.We arent haveing English calss.,3)现在进行时的一般疑问句句型 相应be动词+主语+现在分词+?eg.Are you dancing?Is he drawing a picture?Are you talking with your friend?4)现在进行一般疑问句的答语(1)肯定回答:Yes,主语+相应be动词。(2)否定回答:No,主语+相应be动词+not。eg.Are you listening to the music?Yes,I am./No,I am not.Is Aunt Wang knitting a sweater
5、?No,she isnt.,5)现在进行时的特殊疑问句特殊疑问词+相应be动词+主语+doing+?eg.What are you doing?Who is singing a song?Why are they cleaning their room?现在进行时特殊疑问句的答语回答特殊疑问时,根据不同的疑问词的情况来决定回答方式。回答what提问时,答语是现在进行时的肯定形式;回答who提问时,只需说明主语是谁,再加相应的be动词即可。eg.What is he doing?He is writing a letter.Who is swimming in the lake?Jim is.,
6、四动词的现在分词形式构成方法1.一般动词原形结尾直接在词尾加ing,如:playing,listening,cleaning等等2.重读闭音节单词,末尾以元音字母加一个辅音字母结尾的,双写辅音字母加ing,如:getting,beginning,putting,stopping,sitting,cutting,running,shopping,swimming,setting3.以不发音的字母e结尾,having,coming,writing,taking,making,arriving,living,hoping,注意:(一)、把动词变成现在分词形式易出错例:1、They are swimi
7、ng.(swim)2、Jenny is plaiing(play)football.答案:1.swimming 2.playing解析:动词变现在分词可有如下口诀:“一添一去y不变”.“一添”指双写规则;“一去”指去掉不发音字母e规则;“y不变”指要与名词变复数区分开。,(二).丢掉be动词或忘记把动词变成现在分词 1.Look,two children flying.(fly)a kite in the park.2.Li Mingisnt read(not read)a book in bed now.答案:1.are flying 2.isnt reading解析:现在进行时肯定句的结构
8、规律为:“be+现在分词,缺一不可”。这一点必须牢记。,(三).对动词或动词词组提问时丢掉doing 1.The students are singing in the room.(对划线部分提问)What are the students in the room?答案:What are the students doing in the room?解析:现在进行时态中对动作提问可记住此句式“What+be+主语+doing+其它?”或简写为“What.doing.”?句式。,(四)、现在进行时态的选择疑问句中易忽视or后用现在分词形式例:孩子们在跑还是在跳?Are the children
9、running or jump?答案:Are the children running or jumping?解析:or连接的是两个并列成分,动词形式须一致。,用正确时态完成下列句子:1.What_you_(do)?2.I_(sing)an English song.3.What_he_(mend)?4.He_(mend)a car.5._you_(fly)a kite?Yes,_.6._she_(sit)in the boat?7._you_(ask)questions?8.We_(play)games now.,are doing,am singing,is mending,is mend
10、ing,Are flying,I am,Is sitting,Are asking,are playing,9.Its ten oclock.My mother _(lie)in bed.10.What_he _(mend)?11.We _(play)games now.12.What _ you _(do)these days?13._he _(clean)the classroom?14.Who_(sing)in the next room?15.The girl_(like)wearing a sweater.Look!She _(wear)a red sweater today.,is
