典型例句(含真题 + 正误对比)
一、现在进行时核心基础
1. 核心含义
① 说话当时正在进行的动作
② 现阶段正在进行的动作(未必此刻做)
-
2. 标志词
now、look、listen、at the moment、right now(真题高频)
真题:The boy is reading an English book in the bright room right now.
3. 核心结构
be 动词 (am/is/are) + 动词现在分词 (-ing)
be 动词随主语人称 / 数变化:I 用 am,单三用 is,复数 /you 用 are
① I am reading. / He is running. / They are playing.
② 真题:—Where is Tina? —She is shopping with her friends.
③ 错误:He are running.(修正:is running)
二、四大基本句式
1. 肯定句
主语 + am/is/are + doing + 其他
① She is reading in the library.
② 真题:Look! My sister is setting the table.(look 为标志词,必须用进行时)
2. 否定句
主语 + am/is/are + not + doing + 其他
缩写:isn’t /aren’t(am not 无缩写)
① She isn’t watching TV.
② They aren’t playing football on the playground.
3. 一般疑问句
Am/Is/Are + 主语 + doing + 其他?
回答:Yes, 主语 + am/is/are./ No, 主语 + am/is/are+not.
① Are they playing basketball? — Yes, they are.
② Is he reading a book? — No, he isn’t.
4. 特殊疑问句
特殊疑问词 + am/is/are + 主语 + doing + 其他?
(疑问词:what/where/who/why/how 等,真题考 what/where 居多)
① What are you doing now?
② 真题:I’m shopping in the supermarket. → Where are you shopping for food and drink?
③ 真题:I’m playing the violin now. → What are you doing now?
三、现在分词 (-ing) 变化规则(单元重点)
1. 一般情况
直接加 -ing
play→playing / work→working / shop→shopping
2. 不发音 e 结尾
去 e 加 -ing(注意:发音的 e 不可去,如 see→seeing)
take→taking / dance→dancing / write→writing
3. 重读闭音节(辅元辅)
双写末尾辅音字母 加 -ing(必须满足:重读 + 末尾只有一个辅元辅)
run→running / stop→stopping / set→setting
真题易错:stop→stoping(修正:stopping)
4. ie 结尾
变 ie 为 y 加 -ing(单元基础,了解即可)
lie→lying / die→dying
四、单元拓展句式(高频)
1. 进行时 + 方位介词
主语 + am/is/are + doing + 方位短语(in/on/at/next to 等)
She is reading in the library. / They are playing on the playground.
2. There be + doing 混合句式
There be + 名词 + doing + 地点
(表 “某地有某人 / 物正在做某事”)
There are some people playing basketball on the playground.
3. There be + 方位介词
There be + 名词 + 方位短语(表 “某地有某物”)
There is a bank next to the supermarket.
五、单元高频易错点汇总
1. be 动词漏加 / 错用
进行时必须搭配 be 动词,且需随主语变化,不可省略
① 错误:Look! My sister setting the table.(修正:is setting)
② 错误:I is reading.(修正:am reading)
2. 现在分词形式错误
① 重读闭音节未双写尾辅音
② 不发音 e 结尾未去 e
① 错误:run→runing(修正:running)
② 错误:dance→dancing(正确)/take→takeing(修正:taking)
3. 标志词搭配错误
看到 look/listen/right now 等标志词,未用现在进行时
真题易错:Look! My sister sets the table.(修正:is setting)
4. 现在分词与动词原形混淆
进行时后必须用 doing,不可用动词原形
错误:She is read a book.(修正:is reading)
使用注意事项
1. 现在进行时的核心结构是 “be + 动词 -ing”,缺一不可,例如:They are singing(正确),They singing(错误);He is drawing(正确),He draw(错误)。
2. 当句中出现 now、look、listen、at the moment 等标志词时,需用现在进行时,例如:Listen! Someone is knocking at the door(正确),Listen! Someone knocks at the door(错误)。
3. 动词变现在分词时,重读闭音节单词需双写末尾辅音字母,例如:swim→swimming(正确),swim→swiming(错误);shop→shopping(正确),shop→shoping(错误)。
4. 以不发音的 e 结尾的动词,变现在分词时需去掉 e 再加 -ing,例如:write→writing(正确),write→writeing(错误);take→taking(正确),take→takeing(错误)。
5. be 动词需根据主语人称和数灵活变化,I 搭配 am,he/she/it 及单数名词搭配 is,we/you/they 及复数名词搭配 are,例如:She is cooking(正确),She are cooking(错误)。
