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？
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.
写作指导
一、综合上面阅读材料，请你思考：
1．由上文可知推测时经常用上情态动词。其中，_______ 表示非常有把握(肯定是……)；_______ 表示非常有把握(肯定不是……)__________________表示没有把握 (可能是……)。
2．对现在正在进行的动作进行推测时，用“情态动词＋________”结构；对过去发生了的动作进行推测时用
“情态动词＋__________”结构。
must be
can't be
might/could/may be
be doing
have done
二、写作微技能训练。
用适当的表述进行推测：
1．Many people are wearing coats.
__________________________________________
2．The restaurant is always very crowded.
__________________________________________
3．Whenever I try to read this book，I feel sleepy.
__________________________________________
4．Sally has been coughing a lot.
__________________________________________
5. It's cold and the ground is all white.
___________________________________________
The weather must be cold.
The food there must be delicious.
It can't be interesting./It must be boring.
She might be ill.
It must have snowed.
