课件9张PPT。 单元主题阅读与写作 It must belong to Carla.Unit 8 本单元我们讨论的重点是谈论猜测和判断。对于不确定的事物，我们总想去猜测它是什么，我们如何进行推测呢？ 单元主题阅读与写作佳篇品读 I'm taking a walk with Mr. Wang. I see some students over there on the playground. They run away quickly, leaving something behind them. We go over to the things. They are a backpack, a maths exercise book and a soccer.(1)我认为背包肯定是萨莉的，因为我经常看见她背着它。And the maths exercise book must be Lucy's . Only she can write such special handwriting, because she writes with her left hand. The soccer，Mr. Wang thinks might be Frank's. He likes playing soccer. (2)But it can't be his. There is a “G” on the soccer ball. It must be George's. He also likes playing soccer. And he likes copying others' homework, too. Now, we get to know why they run away. George must be copying Lucy's maths homework because he was busy playing soccer yesterday and had no time to do his homework. They are afraid of us. So they hurried away and left the things as soon as they saw us.任务一：阅读短文，完成下列各题。

This morning，we found that Damion's eyes were red.
What happened to him？We guessed.
Some of the boys thought he must have played computer games all night, because he always spends a long time doing that.But some girls didn't agree.They believed that he must have done his homework very late.Others thought that he was watching TV the whole night，because there was an NBA game last night.But I didn't agree with them.His parents are very strict with him so he couldn't have played games or watched TV.
Then，we asked him during the break，and he said he caught a bad cold. Poor Damion.课件18张PPT。第五课时：Section B
