四年级下册英语Unit 8 What are you doing？ 知识点精讲 教科版（广州）

知识梳理 你在干什么？ 九点了，四位好朋友各待在一间屋子里，Tom想知道别人正在干什么。 ( I’ m washing clothes(洗衣服). ) ( I ’ m reading a book. ) ( I ’ m watching TV. ) ( What are you doing? ) ( Mary Lily Tom Lucy ) 小朋友，你知道“What are you doing?”的意思了吗？它的意思是“你(们)在干什么？”，回答时用“I am/We are+动词-ing”。 Dear friends, what are you doing now? Can you tell us? 智力冲浪 猜猜哪个是我？ 小朋友，你能根据下面的对话圈出Tom来吗？Come on! ( Tom, what are you doing? ) ( I ’ m drinking water . ) 记忆指环 巧记动词加-ing ( 现在分词加-ing，特殊三点要注意。 动词结尾一个e，一刀去掉不留情。 动词结尾两个e，千万镇定直接加。 动词结尾没有e，孤单辅音只一个。 又逢重读闭音节，双写辅音别忘掉。 动词结尾真重要，睁大眼睛仔细瞧。 )悦读越读 Counting Stars One night, John is looking at the sky. Tom is John’s younger brother. He asks John, “What are you doing?” John says, “I’m counting stars.”Tom says, “It’s really dark(黑暗的) now. Why don’t you count them tomorrow morning?” John laughs and says, “That’s not a good idea!” 读短文，判断正(T)误(F)。 ( )1. Tom is older than John. ( )2. John is counting stars
