语法详解
(一)现在进行时的定义
现在进行时是用来表示此时此刻正在进行的动作,或现阶段正在进行的动作(虽然此刻不一定在做)的时态。外研版七上Unit 6围绕“奇妙的朋友、动物互动”展开,现在进行时是描述动物行为、人物即时动作的核心时态,如The pigeon is flying.、We are talking about our pets.。
(二)现在进行时的构成
现在进行时的基本结构为:主语 + am/is/are + 动词的现在分词(v.-ing)+ 其他
1. be动词的搭配规则
· 第一人称单数(I)→ am
· 第三人称单数(he/she/it/单数名词)→ is
· 第二人称单复数(you)、第一人称复数(we)、第三人称复数(they/复数名词)→ are
例:I am watching a pigeon.;She is feeding the birds.;They are playing with animals.
2. 动词现在分词的变化规则
· 规则变化
① 一般情况直接加-ing:play → playing,talk → talking,fly → flying
② 以不发音的e结尾的动词,去e加-ing:take → taking,make → making,write → writing
③ 以重读闭音节结尾,且末尾只有一个辅音字母的动词,双写末尾辅音字母加-ing:run → running,swim → swimming,sit → sitting
④ 以ie结尾的动词,变ie为y加-ing:lie → lying,die → dying(七年级上册拓展)
· 不规则变化:少数动词需特殊记忆,如be → being
(三)现在进行时的用法
1. 表示此时此刻正在进行的动作
· 常与时间状语now(现在)、at the moment(此刻)连用,也可通过语境或提示词(如Look! / Listen!)体现。
例:Look! The pigeon is flying towards us.(看!那只鸽子正朝我们飞来,Unit 6核心语境);She is feeding the dog now.(她现在正在喂狗)。
2. 表示现阶段正在进行的动作
· 动作不一定在此时此刻发生,但在当前一段时间内持续进行,常与these days(这些天)、this week(这周)等时间状语连用。
例:We are learning about pigeons this week.(我们这周正在学习关于鸽子的知识);He is writing a story about his pet these days.(他这些天正在写一个关于宠物的故事)。
3. 表示即将发生的动作(少数表示位移的动词)
· 如go、come、leave、arrive等,用现在进行时可表示按计划即将发生的动作。
例:They are coming to the zoo tomorrow.(他们明天要来动物园)(七年级上册拓展)。
(四)现在进行时的句式变换
1. 肯定句:主语 + am/is/are + v.-ing + 其他。
例:The cat is sleeping on the sofa.
2. 否定句:主语 + am/is/are + not + v.-ing + 其他。
例:She is not playing with the rabbit.;We aren't talking about animals.
3. 一般疑问句:Am/Is/Are + 主语 + v.-ing + 其他?
肯定回答:Yes, 主语 + am/is/are.
否定回答:No, 主语 + am/is/are + not.
例:—Is the bird singing?—Yes, it is./No, it isn't.
4. 特殊疑问句:特殊疑问词 + am/is/are + 主语 + v.-ing + 其他?
例:—What are you doing?—I am reading a book about pigeons.;—Who is feeding the ducks?—Li Ming is.
(五)高频易错点
1. 现在分词形式错误
· 错误:He is play football.(应为playing);She is write a letter.(应为writing);They are runing.(应为running)。
2. be动词遗漏或搭配错误
· 错误:I watching TV now.(应为am watching);He are feeding the fish.(应为is feeding)。
3. 与一般现在时混淆
· 错误:She is often play with her cat.(表示习惯性动作应用一般现在时,应为She often plays with her cat.)。
4. 瞬间动词误用现在进行时
· 错误:The boy is dying the apple.(die是瞬间动词,此处表“切苹果”应为cutting,die表“死亡”时也不可用于持续进行)。
