Unit3语法专项—— 现在进行时(The Present Continuous)
全解精讲+分层练习
学习目标
1. 理解现在进行时的核心定义,分清两种核心用法的区别。
2. 熟练掌握现在进行时的肯定、否定、疑问句式结构。
3. 牢记动词-ing的4种变化规则,能准确写出动词-ing形式。
4. 分清可用于和不可用于现在进行时的动词,避免误用。
5. 能完成多种题型练习,灵活运用现在进行时解决实际题目。
现在进行时—定义详解
核心定义:表示两种场景的动作,是七下重点语法之一。
1. 此时此刻正在进行/发生的动作(强调“正在做”)。
例:I am reading a book now.(我现在正在看书)
2. 现阶段正在进行,但此刻不一定正在做的动作(强调“现阶段”)。
例:She is learning English these days.(她这些天在学英语)
现在进行时—核心结构(肯定句+否定句)
一、肯定句:主语 + am/is/are + 动词-ing
搭配规则:I用am,you用are,he/she/it用is
例句:He is playing football.(他正在踢足球)
二、否定句:主语 + am/is/are + not + 动词-ing
口诀:肯定句变否定,be动词后面加not
例句:She is not watching TV.(她没在看电视)
现在进行时—核心结构(疑问句)
一、一般疑问句:Am/Is/Are + 主语 + 动词-ing + 其他?
回答:Yes, 主语 + am/is/are. / No, 主语 + am/is/are + not.
例句:—Are you reading (你在看书吗?)—Yes, I am. / No, I’m not.
二、特殊疑问句:疑问词 + am/is/are + 主语 + 动词-ing + 其他?
常用疑问词:what, who, where, how
例句:What is he doing (他正在做什么?)
动词-ing变化规则(一)——一般情况+不发音e结尾
规则1:一般动词(无特殊变化),直接加-ing
例:work → working(工作)、feel → feeling(感觉)
eat → eating(吃)、wait → waiting(等待)
规则2:以不发音的e结尾,去e后加-ing
核心要点:e不发音才去,发音e不删(如see→seeing)
例:write → writing(写)、make → making(制作)
动词-ing变化规则(二)——ie结尾+重读闭音节
规则3:以ie结尾的动词,变ie为y,再加-ing
例句:tie → tying(系)、lie → lying(躺)
die → dying(死)
规则4:重读闭音节(辅元辅结构),双写末尾辅音加-ing
核心要点:重读、闭音节、末尾辅元辅,三者缺一不可
例句:run → running(跑)、stop → stopping(停止)
动词-ing变化规则—易错点提醒
1. 不发音e结尾:区分“发音e”和“不发音e”,避免误删e。
错误:see → seeing(正确:seeing,e发音不删)
2. 重读闭音节:末尾只有一个辅音才双写,多辅音不双写。
错误:work → working(正确:working,末尾k前是or,非辅元辅)
3. ie结尾:牢记“变ie为y”,不可直接加-ing。
错误:tie → tieing(正确:tying)
现在进行时用法(一)——此刻正在进行的动作
用法1:表示此时此刻(说话瞬间)正在进行的动作。
标志词:now(现在)、right now(此刻)、look(看)、listen(听)
例句1:Look! They are watering the trees.(看!他们正在浇树。)
例句2:Right now, my mother is cooking dinner.
例句3:Listen! Someone is singing in the next room.
现在进行时用法(二)——现阶段正在进行的动作
用法2:表示现阶段正在进行,但此刻不一定正在做的动作。
标志词:these days(这些天)、this week(这周)、recently(最近)
例句1:We are working on our group project these days.
例句2:He is learning to swim this month.(他这个月在学游泳。)
例句3:My father is busy these days; he is writing a report.
现在进行时用法(三)——即将发生的动作
用法3:表示即将发生的动作,仅限“移动性动词”使用。
常用移动性动词:go(去)、leave(离开)、come(来)、arrive(到达)
标志词:tomorrow(明天)、next week(下周)、soon(很快)
例句1:He is leaving for Beijing tomorrow.(他明天要去北京。)
例句2:They are coming to our school next Monday.
不用于现在进行时的动词(一)
核心原则:表示状态、情感、感官的动词,通常不用现在进行时。
这类动词表示“静态”,而非“动态动作”,常用一般现在时。
第一类:表情感的动词
常见词汇:like(喜欢)、love(爱)、hate(讨厌)、want(想要)、prefer(更喜欢)
例句:I like eating apples.(不用am liking)
不用于现在进行时的动词(二)
第二类:表认知的动词
常见词汇:know(知道)、believe(相信)、understand(理解)、
例句:He knows the answer.(不用is knowing)
错误:I am understanding your problem.
(正确:I understand your problem.)
第三类:表感官的动词
常见词汇:hear(听见)、see(看见)、smell(闻起来)、taste(尝起来)例句:The cake tastes good.(不用is tasting)
易混点辨析—现在进行时vs一般现在时
1. 现在进行时:表“正在做”或“现阶段进行”,强调动作的持续性。
标志词:now, look, listen, these days
例句:She is reading a book now.(此刻正在读)
2. 一般现在时:表“经常性、习惯性动作”或“客观事实”。
标志词:every day, usually, always, often
例句:She reads books every evening.(每天晚上读)
辨析:He is eating an apple.(正在吃)vs He eats apples every day.(习惯吃)
