Keygrammar
现在进行时态
一、现在进行时的用法
1、表示说话时正在进行或发生的动作。如:
I’mbabysittingmyyoungerbrother.我在照看我弟弟。
It’srainingoutside.外面正在下雨。
2、表示现阶段一直在进行或不断重复的动作,但说话时该动作并不一定在进行。如:
He’swatchinganinterestingTVplaythesedays.
近来,他在看一部很有趣的电视剧。
AreyouteachingEnglishinaschool?你在学校教英语吗?
3、表示最近的确定安排,即根据计划或安排在近期内将要发生的动作。这是表示眼前打算最普通的说法,但一般要与表示将来的时间连用,以避免现在进行时和一般将来时的含义上的混淆。例如:
I’mmeetingyouattheairportthisevening.今晚,我会到机场接你。
Whatareyouhavingfordinner?晚饭吃什么?
4、表示从一个地方到另一个地方位置移动的动词(如go,come,drive,fly,travel,arrive,leave,start,visit,run,return等),以及动词do等的现在进行时形式,可以用来表示没有确定安排的决定或计划。
He’sleavingforBeijingtomorrow.他明天动身去北京。
WhatareyoudoingnextSunday?下星期天你要干什么?
5、现在进行时和always,usually,allthetime等连用时,表示一种经常、反复的动作,且说话人往往带有某种感情色彩(如赞扬、欣赏、厌烦、批评、惊讶、不理解等)。例如:
She’salwayshelpingothers.她总是乐于助人。(表示赞赏)
Youarealwaystalkinginclass.你上课老是说话。(表示批评)
二、现在进行时的谓语部分构成
现在进行时在句式的变化上,都应在助动词be上做文章。
1、肯定式:be(am,is,are)+Ving(现在分词)如:
TheyarehavinganEnglishclass.他们在上英语课。
2、否定式:be(am,is,are)+not+Ving(现在分词)如:
Theyaren’thavinganEnglishclass.他们不在上英语课。
3、疑问式:将be的具体形式(即am,is或are)提前到句首。如:
AretheyhavinganEnglishclass?他们在上英语课吗?
助动词变化口诀:变疑问,往前提,句后问号莫丢弃;变否定,更容易,be后not莫忘记。
三、现在分词的变化规则
1、一般在词尾加-ing(一般-ing)。例如:going,playing,knowing
2、以不发音的字母e结尾,先去e再加-ing(去哑e)。例如:making,arriving,coming
3、以重读闭音节结尾,且词尾只有一个辅音字母时,先双写这个辅音字母,再加-ing(重闭单辅先双写)。例如:running,stopping,preferring
4、以-ie结尾,先将-ie改成y,再加-ing。例如:tying,dying,lying
口诀:现在进行ing,以e结尾要去e,除去几个特殊词,系住tie-tying死去die-dying要躺下lie-lying,直接ie变成y。
四、现在进行时态的常见提示语
1、在汉语中,通常有“在,正在”等提示词。如:
我在做作业。Iamdoingmyhomework.
2、在英语中,最常见的提示词有now,look,listen以及atthemoment(此时此刻)等。如:
Look,theyareplayingfootball.瞧!他们在踢足球。
五、运用现在进行时常见的几个错误
1、把动词变成现在分词形式易出错。例:
(1)误:Theyareswiming(swim).
正:Theyareswimming(swim).
(2)误:Jennyisplaiing(play)football.
正:Jennyisplaying(play)football.
解析:A、动词变现在分词可有如下口诀:一般-ing;哑e先去e;重闭单辅先双写;-ie结尾y来替。
B、动词现在分词的变化规则要与名词变复数、动词变现单三等规则区分开来。
2、谓语部分的构成不完整:丢掉be动词,或忘记把动词变成现在分词。例:
(1)误:Look!Twochildrenflying(fly)akiteinthepark.
正:Look!Twochildrenareflying(fly)akiteinthepark.
(2)误:LiMingisn’tread(notread)abookinbednow.
正:LiMingisn’treading(notread)abookinbednow.
解析:现在进行时的谓语部分的构成是“be+现在分词”,二者缺一不可,这一点必须要牢记。
3、对动词或动词词组提问时,丢掉代动词doing。例:
Thestudentsaresingingintheroom.(对划线部分提问)
→误:Whatarethestudentsintheroom?
→正:Whatarethestudentsdoingintheroom?
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。
4、现在进行时态的谓语部分是并列结构时,容易忽视第二个以及第二个以后的动词用现在分词形式。例:
孩子们在跑还是在跳?
误:Arethechildrenrunningorjump?
正:Arethechildrenrunningorjumping?
解析:or连接的是两个并列成分,动词形式须一致。
