Language points
1. belong to 属于，为……所拥有
2. 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。
一、belong to
Whose book is this?
It must be Mary’s. J.K.Rowling is her favorite writer.
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”，
mustn’t表示“不准；禁止”。
二、must的用法
Must I finish the work on time?
Yes, you must.
Must she return it?
No, she needn’t.
Must we wear uniforms?
No, we don't have to.
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。
It must be Mary’s. J.K.Rowling is her favorite writer.
There must be something wrong with the computer.
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。
It must be Linda's.
No, it can't be Linda's.
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。
三、probably的用法
Whose CD is this?
This would probably be Sally's. She loves music.

probably

possibly
“很可能；大概”肯定意味最浓，相当于most likely
He will probably
pass the exam.
“可能；或许”，语气
弱于probably，可与could 连用，表示委婉的请求，也可以与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.
{16D9F66E-5EB9-4882-86FB-DCBF35E3C3E4}maybe
perhaps
“可能；也许”，语气不确定。常用于口语中，多位于句首。

或许他知道真相。
This is perhaps her best novel.
