四年级英语上册教程——现在进行时与一般疑问句

概述

四年级是小学英语学习的过渡阶段,从简单的词汇和对话开始进入初步的语法学习。四年级上册英语的重点是现在进行时一般疑问句与特殊疑问句的系统学习,同时积累更多常见动词短语,学会描述正在进行的日常活动。

本教程将详细讲解这些核心知识点,配合丰富的例句和练习题,帮助同学们理解和掌握这些语法内容,为更高年级的英语学习打下坚实基础。


核心知识点一:现在进行时的基本用法

1.1 什么是现在进行时?

现在进行时用来表示现在正在进行的动作或正在发生的事情。在中文里,我们用"正在……"来表达,比如"我正在读书"、"他正在跑步"。

1.2 现在进行时的构成

现在进行时的基本结构是:

主语 + be动词(am/is/are)+ 动词-ing + 其他

其中:

  • I 后面用 am(I am reading.)
  • he/she/it/单数名词 后面用 is(He is running.)
  • you/we/they/复数名词 后面用 are(They are playing.)

缩写形式:

  • I am = I'm
  • He is = He's
  • She is = She's
  • It is = It's
  • We are = We're
  • They are = They're
  • You are = You're

1.3 动词加-ing 的规则

动词变成-ing形式有以下几种规则:

规则一:一般情况下直接加-ing

  • read → reading(读)
  • play → playing(玩)
  • sing → singing(唱)
  • draw → drawing(画)

规则二:以不发音的e结尾,去e加-ing

  • make → making(做)
  • write → writing(写)
  • dance → dancing(跳舞)
  • ride → riding(骑)

规则三:以重读闭音节结尾(辅+元+辅),双写末尾字母加-ing

  • run → running(跑)
  • swim → swimming(游泳)
  • sit → sitting(坐)
  • get → getting(获取)

规则四:以ie结尾,变ie为y加-ing

  • die → dying(死)
  • lie → lying(躺)

1.4 现在进行时的例句

肯定句:

  • I am reading a book.(我正在读书。)
  • She is singing a song.(她正在唱一首歌。)
  • They are playing football.(他们正在踢足球。)
  • The cat is sleeping on the sofa.(猫正在沙发上睡觉。)

否定句(在be动词后加not):

  • I am not watching TV.(我没有在看电视。)
  • He is not (isn't) doing his homework.(他没有在做作业。)
  • They are not (aren't) swimming.(他们没有在游泳。)

核心知识点二:一般疑问句的构成与回答

2.1 什么是一般疑问句?

一般疑问句是用来询问某事是否属实的问句,通常用"Yes"或"No"来回答。在书写时,一般疑问句末尾用问号"?"。

2.2 be动词引导的一般疑问句

构成方法:将be动词提到主语前面。

肯定句 一般疑问句
You are a student. Are you a student?
She is reading. Is she reading?
They are playing. Are they playing?

回答方式:

  • Are you a student? — Yes, I am. / No, I'm not.
  • Is she reading? — Yes, she is. / No, she isn't.
  • Are they playing? — Yes, they are. / No, they aren't.

注意: 简略回答中,不能用缩写形式:

  • Yes, I am.(✓) 不能说 Yes, I'm.(✗)
  • No, I'm not.(✓) 不能说 No, I not.(✗)

2.3 助动词 do/does 引导的一般疑问句

对于不是用be动词的句子,需要借助助动词 do 或 does:

主语是第一/二人称或复数时,用do:

  • You like apples. → Do you like apples?
  • They have a dog. → Do they have a dog?

主语是第三人称单数时,用does:

  • She likes apples. → Does she like apples?
  • He has a dog. → Does he have a dog?

注意: 使用does后,动词要恢复原形:

  • Does she likes apples?(✗)
  • Does she like apples?(✓)

2.4 can 引导的一般疑问句

将 can 提到主语前面即可:

  • You can swim. → Can you swim? — Yes, I can. / No, I can't.
  • She can dance. → Can she dance? — Yes, she can. / No, she can't.

核心知识点三:特殊疑问句

3.1 什么是特殊疑问句?

特殊疑问句是以疑问词开头的问句,用来询问具体信息,不能用"Yes/No"回答。

3.2 常见疑问词及用法

What(什么)— 询问事物

  • What are you doing?(你正在做什么?)
    • I'm drawing a picture.(我正在画一幅画。)
  • What is she reading?(她在读什么?)

    • He's going to the park.(他要去公园。)
  • Where are they playing?(他们在哪里玩?)

    • I get up at seven.(我七点起床。)

Why(为什么)— 询问原因

  • Why are you crying?(你为什么哭?)
    • Because I'm sad.(因为我很伤心。)

3.3 特殊疑问句的构成

疑问词 + 一般疑问句语序?

例如:

  • What + are you doing? → What are you doing?
  • Where + is he going? → Where is he going?
  • Who + is singing? → Who is singing?(who作主语时语序不变)
