当某件事此刻正在发生时，英语通常用现在进行时，而不是一般现在时：I am reading this sentence. She is talking on the phone.

速记结构：主语 + am / is / are + 动词**-ing** → I am working. They are talking.

现在进行时怎么构成

这里用到的助动词是 be，也就是动词"to be"里的 am / is / are。然后再加上主动词的 -ing 形式。

主语 助动词 -ing形式 例句
I am working I am working today.
he / she / it is reading He is reading a book.
you / we / they are talking You are talking to your friend.

am / is / are的选择规则和你已经知道的完全一样：I → am；he/she/it → is；you/we/they → are。

-ing形式的拼写

动词情况 规则 例子
大多数动词 直接加**-ing** work → working，go → going
词尾不发音的 -e 去掉 -e，加**-ing** make → making，write → writing
-ee结尾和be 保留e see → seeing，be → being
单音节动词，以“短元音 + 词尾辅音”结尾 双写词尾辅音（w/x/y 除外） run → running，sit → sitting，fix → fixing
-ie结尾 改成**-y**，加**-ing** lie → lying，die → dying

此刻正在发生的事情

最常见的用法：表示某个动作此刻正在进行。

  • I am doing my homework.
  • She is cooking dinner.
  • Look! It is raining.
  • They are watching TV right now.

这段时间正在发生的事情（不一定是这一秒）

现在进行时也可以用来说这段时间正在发生的临时情况，即使动作不是这一秒正在进行：

  • I am learning English this year.
  • He is reading a great book at the moment.（他此刻不一定正在读，但这本书还没读完）
  • We are staying with friends this week.

一般现在时还是现在进行时

这两种时态很容易混淆。一般现在时用来表示习惯或普遍事实；现在进行时用来表示此刻或这段时间正在发生的事情：

  • ✅ I work in a hospital.（通常情况——这是我的工作）对比✅ I am working late today.（此刻／这个具体的日子）
  • ✅ *She usually walks to school.*对比✅ She is walking to school right now.

中文表达"正在发生"和"经常发生／一般情况"时，动词本身不变，通常靠"在""正在"等词，或者靠上下文来区分；主语也不会影响动词形式。英语则不同：不仅要选对is working还是works，be动词本身还要随主语变化（am/is/are），这一步在中文里没有对应变化，容易漏掉。

now、right now、at the moment、*Look!*这类词常常提示要用现在进行时。usually、every day这类词常常提示要用一般现在时——详见频度副词。

否定句

在am / is / are后面直接加not。缩略形式非常常见：

  • I am not working today. → I'm not working today.
  • He is not listening. → He isn't listening. / He's not listening.
  • They are not sleeping. → They aren't sleeping. / They're not sleeping.

疑问句

把am / is / are放到主语前面构成疑问句：

  • Are you listening?
  • Is she working today?
  • What are you doing?
  • Why is he crying?

简短回答时，要保留am、is或are：

  • "Are you working?" — "Yes, I am." / "No, I'm not."

状态动词通常不用进行时

有些动词通常表示状态，而不是正在进行的动作——know、like、want、understand、love、need。即使是在谈论现在的情况，这些动词通常也用一般现在时：

  • ❌ I am knowing the answer. → ✅ I know the answer.
  • ❌ She is wanting a coffee. → ✅ She wants a coffee.
  • ❌ I am needing help. → ✅ I need help.

常见错误

  • ❌ I working now. → ✅ I am working now.（别忘了am/is/are）
  • ❌ She is work now. → ✅ She is working now.（需要*-ing*形式）
  • ❌ He is runing. → ✅ He is running.（要重复辅音：run → running）
  • ❌ I am know the answer. → ✅ I know the answer.（状态动词通常不用*-ing*形式）
  • ❌ What you are doing? → ✅ What are you doing?（疑问句中am/is/are要放在主语前面）

小测验

写出现在进行时：

  1. (I / read) a book right now.
  2. (she / not / listen) to music at the moment.
  3. (they / play) football now.
  4. (what / you / do)?
显示答案
  1. I am reading a book right now.   2. She isn't listening to music at the moment.   3. They are playing football now.   4. What are you doing?

要点回顾

  • 现在进行时 = am / is / are + 动词-ing——表示现在或这段时间正在发生的事情。
  • 用法包括：此刻正在进行的动作，或者这段时间正在发生的临时情况。
  • 表达习惯和一般事实要用一般现在时，而不是进行时——I work对比I am working。
  • 否定句：isn't / aren't / I'm not + -ing。疑问句：am/is/are + 主语 + -ing?
  • 状态动词（know、want、like……）即使说的是现在，通常也用一般现在时。
