2026-2027学年仁爱科普版七年级英语上册核心语法精讲精练
(新教材)Unit 4 Fun in the Sun!
核心语法:现在进行时
一、核心概念
现在进行时表示此刻正在进行的动作或现阶段正在持续的状态。它强调动作的“进行中”,而不是强调动作的完成或结果。
核心含义: “正在做……”
时间轴理解:
二、基本结构
构成:am/is/are + 现在分词(V-ing)
主语 | 肯定式 | 否定式 | 疑问式 |
I | am working | am not working | Am I working? |
He/She/It | is working | is not working | Is he working? |
You/We/They | are working | are not working | Are you working? |
缩略形式:
肯定:I'm, he's, she's, it's, we're, you're, they're
否定:I'm not, he isn't / he's not, they aren't / they're not
现在分词(V-ing)的构成规则:
规则 | 原形 | V-ing | 记忆要点 |
一般情况直接 +ing | read | reading | 大多数动词 |
规则 | 原形 | V-ing | 记忆要点 |
| play | playing |
|
以不发音 e 结尾,去 e +ing | write | writing | 去掉e再加ing |
重读闭音节结尾,末尾只有一个辅音字母,双写该辅音 +ing | sit | sitting | 辅+元+辅,双写末尾辅音 |
以 ie 结尾,变 ie 为 y +ing | lie | lying | ie→y+ing |
以 y 结尾(非 ie) | play | playing | 直接+ing |
重读闭音节判断技巧:
单词末尾是“辅音字母 + 元音字母 + 辅音字母”
该音节是重读音节
符合条件则双写末尾辅音字母
常见重读闭音节动词(七年级必背):
单音节词:run, sit, swim, put, get, stop, begin, shop, plan, cut, dig, win
双音节词(重音在第二音节):begin, prefer, forget
三、四大核心用法
用法1:表示此时此刻正在进行的动作
常与 now, at the moment, right now 等时间状语连用,或通过上下文暗示此时此刻。
What are you doing now? (你现在在做什么?)
I am reading a book. (我正在看书。)
She is singing at the moment. (她此刻正在唱歌。)
Listen! Someone is playing the piano. (听!有人在弹钢琴。)
Look! The children are dancing. (看!孩子们正在跳舞。)
用法2:表示现阶段正在进行的动作(不一定此刻)
表示最近一段时间内持续进行的动作,但说话的此刻不一定正在做。常与 these days, this week, this month, this term 等时间状语连用。
I am studying for the exam these days. (这些天我正在为考试复习。)
He is reading a novel this week. (这周他正在读一本小说。)
They are preparing for the sports meeting. (他们正在为运动会做准备。)
This term, we are learning English grammar. (这学期我们在学英语语法。)
用法3:表示按计划即将发生的动作(现在进行时表将来)
用于表示已经安排好的近期将来计划,尤其与位移动词连用(go, come, leave, start, arrive, return, fly, drive 等)。
I am leaving for Beijing tomorrow. (我明天要动身去北京。)
We are having a party this Saturday. (我们这周六要办个派对。)
He is coming back next week. (他下周回来。)
The train is arriving in ten minutes. (火车十分钟后到达。)
用法4:与 always, constantly 连用,表达感情色彩
与 always, constantly, forever 等副词连用,表示反复发生的动作,带有说话人的夸奖、批评、抱怨等感情色彩。
She is always helping others. (她总是帮助别人。)→ 赞美
He is constantly complaining. (他总是抱怨。)→ 不满
You are always leaving things behind! (你总是丢三落四!)→ 批评
四、现在进行时 vs 一般现在时(核心对比)
这是七年级最重要的易混点之一。
对比维度 | 现在进行时 | 一般现在时 |
时间焦点 | 此时此刻或现阶段 | 通常情况或经常性 |
