现在进行时 （PEP Book 6 Unit 4 / Unit 5 s/ Unit 6）用法
Hello, boys and girls. Nice to see you again. "我"是现在进行时，用来表示正在进行或发生的动作。"我"的结构是：be (am, is, are)+动词现在分词形式。
首先，"我"向你们展示"我"的几种句型：
一、陈述句(肯定句)
主语＋be (am, is, are)+现在分词，如：
I am reading English.我正在读英语。He is writing.他正在写字。You are running.你正在跑步。
二、一般疑问句
Be(Am, Is, Are)+主语＋现在分词， 如：
1. -Are you singing?你正在唱歌吗？
-Yes, I am.是的，我在唱歌。(No, I'm not.不，我不在唱歌。)
2. -Is he (she) listening to music?他(她)在听音乐吗？
-Yes, he (she) is.是的，他(她)在听音乐。[No, he (she) isn't.不，他(她)不在听音乐。
三、特殊疑问句
疑问词＋be (am, is, are)＋主语＋现在分词，如：
1. -What are you doing? 你正在干什么？
-I am doing my homework.我正在做作业。
2. -What is he (she) doing?他(她)正在干什么？
-He (She) is riding a bike.他(她)正在骑自行车。
四、现在进行时表示现在正在进行或发生的动作，也可表示当前一段时间内的活动或现阶段正在进行的动作。
五、动词加ing的变化规则
1.一般情况下，直接加ing，如：cook-cookin
以不发音的e结尾，去e加ing，如：make-making, taste-tasting
如果末尾是一个元音字母和一个辅音字母，双写末尾的辅音字母，再加ing，如：run-running, stop-stopping
六、需要掌握的进行时变化形式：sleeping, climbing, fighting, swinging, drinking water。
drawing pictures, doing the dishes, cooking dinner, reading a book, answering the phone，listening to music, washing clothes, cleaning the room, writing a letter, writing an e-mail，flying, jumping, walking, running, swimming，sleeping, climbing, fighting, swinging, drinking water.
其次，"我"向你们介绍"我"的三位好伙伴： look(看)、listen(听)、now(现在)，它们和"我"经常出现在句子中。请看：
Look! Jack is swimming.看！杰克正在游泳。
Listen! She is singing.听！她正在唱歌。
I am cleaning my room now.现在我正在打扫房间。
听了"我"的自述后，小朋友们，你们一定更加了解"我"了吧。
动名词 （PEP Book 7 Unit 4 I have a pen pal）用法
