五下③：正在发生什么——现在进行时

5年级·下册/阶段；建议分2—4次完成。先独立作答，再核对；能看懂不等于能独立写对。

学习目标

• P30.1 用am/is/are＋动词-ing描述图文设定中正在进行的动作
• P30.2 掌握-ing常见拼写并进行否定、一般疑问和what问句转换
• P30.3 区分now提示的当前动作与usually提示的日常习惯

先备与学习方法

前课：en-primary-05b-02。先看例子，再遮住答案写出自己的句子。手写时保留空格；不会的词可先查本课词库，复测时不查。

词汇与用法

核心讲解

现在进行时的两部分缺一不可：主语＋am/is/are＋动词-ing。I am reading. / She is reading. / They are reading.。不能只写She reading，也不能写She is read。

-ing拼写：多数直接加，play→playing；常见不发音e结尾去e，make→making、write→writing（see→seeing不是此类）；一个重读闭音节、末尾单个辅音且前面单个元音的常见词双写，如run→running、swim→swimming。小学先记本课高频实例，不乱给所有词双写。fly→flying，不能套用第三人称studies的规则写fliing。

否定在be后加not：She isn't reading.；问句把be提前：Is she reading?；问正在做什么：What is she doing?，答She is reading.。简答Yes, she is.，不需重复reading。

比较：She usually reads after school.是习惯；She is reading now.是正在进行。同一人物可以拥有习惯，又在此刻做另一件事，不是互相矛盾。

例题解析

例1：They __ (swim) now. 主语they选are，swim双写m＋ing，完整填are swimming。

例2：把Ben is making a card.改what问句：What is Ben doing?。问的是动作，不用What does Ben do?，后者可问职业/习惯。

原创阅读

It is four o’clock. The pupils are in the park. Mei usually reads at this time, but today she is drawing a tree. Ben is running near the lake. Two birds are flying above the trees. Sam is not playing football. He is looking for his cap. His friends are helping him.

词义支架：at this time＝在这个时刻；today＝今天。
