四年级下册M1M2M3M4知识点整理

[学习目标]：

一、现在进行时是表示现在正在进行的动作或事情，其肯定句的构成是：

主语+be(am, are或is)+动词ing形式+其他。例：

We are reading books.

二、现在进行时的否定陈述句，同样在be后加not。

You are reading. ----You are not reading.

三、现在进行时态的肯定陈述句变成一般疑问句时，只把助动词be提前到句

首，用Yes或No回答。

He is running.---- Is he running ?Yes ,he is ./No, he is not.

四、用现在进行时态提问的特殊疑问句有：What(什么)，Where（哪里），

Who(谁)，Whose(谁)等 What are you doing?

Where are they jumping? Who is singing?

Whose father is cleaning the car? [家教点窍]：

一、 句子中有now要用现在进行时态表示，此外，从上下句中判断该句

是否要用现在进行时态表示。 1．She is dancing now?

2．It’s time to the boy. The pupils are eating lunch. 二、 但并不是有now的句子都用现在进行时态表示，如：

1．You can go to school now.

三、 对现在进行时态表示的句子，用一般疑问句形式提问和回答时，与

从前学过的其他句子一样，注意人称转换。 Are you reading your book?

Yes, I am. (I am reading my book.)

四、 对于现在进行时态的句子，一般不用When对now提问。

五、 用Where 提问时，对于类似We are eating supper at home.的句

子，不能仅用Where are you 提问，这样的句子不是现在进行时态的特殊疑问句，对原句来说提问不完整，正确提问方式是Where are you eating supper? [典型例题]
