[Grammar]
It must be Mary’s. J.K. Rowling is her favorite writer. 它一定是玛丽的。J.K. 罗琳是她最喜欢的作家。
【词汇解读】
(1)must为情态动词，无人称和数的变化，后接动词原形。注意在回答must引起的一般疑问句时，否定式常用needn’t或don’t have to，意为“没必要”，而mustn’t表示“不准；禁止”。
eg: ——Must I finish the work on time？
我必须按时完成任务吗
——Yes, you must. /No, you needn’t / don’t have to.
是的，你必须。/不，你没有必要。
（2）此处must表示推断，通常与be连用，意为“一定是，肯定是”。 must这种表示推测的用法只用于肯定句中.
eg：There must be something wrong with the computer.
电脑肯定有点问题。
（3） 当must（一定）、might（也许）或could（可能）表示肯定推测时，其否定形式都是can’t，意为“不可能”，表示有把握的否定推测。
eg：We must be wrong. （改为否定句）
→ We can’t be wrong.

1.Use “must” to show that you think something is probably true.用“must ”来表明你认为某事很可能是符合事实的。
【词汇解读】
probably 是副词，意为“很可能；大概”，表示推测，常位于助动词、情态动词、连系动词之后，行为动词之前，也可以直接位于句首。在否定句中，probably不能位于否定词之后，可放在否定词前或直接放在句首。
probably的形容词形式为probable, 表示“可能发生的；很可能的”。
eg: This would probably be a good time to have a rest.
这很可能是休息的好机会。
I will come next week, probably on Friday.
我下周会来，可能在周五。
I probably didn’t try hard enough.
我也许努力得不够。
【辨析】probably , possibly , maybe与perhaps
probably 意为“很可能；大概”肯定意味最浓，相当于 most likely He will probably pass the exam. 他很可能通过考试。
possibly 意为“可能；或许”，语气弱于probably,可与could 连用，表示委婉的请求，也可以can’t等否定词连用，用于加强语气，强调不可能。 This task is possibly the most difficult.这项任务也许是最难的。
maybe 意为“可能；也许”，语气不确定。常用于口语中，多位于句首。 Maybe he knows the truth.或许他知道真相。
perhaps 相当于maybe,但比maybe要正式，可位于句首，也可位于句中。 This is perhaps her best novel.这也许是她最好的小说。
2.This hair band might belong to Linda.
这条发带可能属于琳达。
【短语解剖】
belong to意为“属于，为……所拥有”。 belong to没有被动语态，也不能用于进行时态。belong to 后可接名词或代词作宾语，常可与“be+名词性物主代词”结构互换
eg：The blue sweater belongs to Li Ming. His mother bought it for him yesterday.
The boy belongs to the singing group of Grade One.
This book belongs to me.=This book is mine.
That new bike in the corner belongs to Helen.

2. 写作指导：
本单元写作是讲述一件发生在周围的奇怪的事，同时运用表推测的情态动词对事情进行解密。把握好情态动词以及事件的逻辑顺序是写好作文的关键。
用情态动词表达猜测或判断，常见的有：must, may, might, could和can't等词。情态动词表示推测，可能性从小到大依次为：can't, might, may, could, must.
本单元话题涉及多种时态，因此要注意时态的正确使用。
常用句型归纳如下：
1)...something strange happened in..;
2) ...must be...;
3)...can’t be...;
4)...might be...
3. Ss try to write a short article.
【Possible version】
No More Mystery in the Neighborhood
Last week, in a quiet neighborhood, something strange happened. Residents heard noises in the night but no one knew why. Victor Smith thought that it was teenagers having fun while Mrs. Smith and neighbor, Helen Jones, blamed it on animals.
We now know what was happening in the neighborhood. A ranger’s station is being built in the nearby forest.
Trees had to be cut down to make space for the station. This affected some animals living in the forest. A raccoon family lost their home and had problems finding food. The raccoons discovered food in the neighborhood’s garbage bins, so they came back every night.
Now the mystery is solved. People in the neighborhood feel sorry for the raccoons and they are trying to help them.

3. Let some students read their sentences to the class.
4. Correct the mistakes they have.
5.Give some possible sentences.
V. Language points
1.But I’m not sure if he likes rock music。
但我不知道他是否喜欢摇滚乐。
【短语解析】
be sure是表示肯定的意思，表不确定时为be not sure, be/make sure 在祈使句中表示“ 确保、肯定”。
eg：Be sure you will get there at six in the morning.
保证你可以在早上六点到达那里。
Make sure the answers are right.
确保答案是正确的
sb is not sure 意为“某人不知道”，相当于动宾结构的sb doesn’t know.
eg：I’m not sure if she will come tomorrow.
=I don’t know if she will come tomorrow.
He isn’t sure when the class meeting will begin.
=He doesn’t know when the class meeting will
begin.
2. So I might be a bit late for the party.
因此我可能聚会要晚到一点。
【短语解读】
a bit和a little都作“一点儿”讲，但用法不同。
（1）a bit和a little在肯定句中修饰动词、形容词、副词和比较级时可以互换，表示“一点儿”的意思。
eg: That’s a bit too expensive.
The speaker spoke up a bit/a little to make.
（2）a bit和a little在否定句中的意思恰恰相反，not a bit相当于not at all“一点儿都不”；not a little相当于very(much)或extremely“很、非常”。
eg: She is not a bit tired. =She is not tired at all.
She is not a little tired.
（3）a bit用作定语时，意为“一点儿”，不能直接修饰不可数名词，但可用“a bit of ＋不可数名词”结构，此时a bit of ＝ a little．
eg：He has a bit of／a little money left．
She knows a bit of ／a little French.
