－Who does this watch _____
－It’s Linda’s．
A. be B. belong to
C. belong D. have
【解析】所有关系可以有两种表达：belong to sb. 和be sb.’s。因问句用疑问词who来提问，故表达为“Who does this watch belong to ”。改为同义句，则其疑问词应用whose，即“Whose is this watch ”。显然本题应是第一种结构，故选B。
B
--- Do you know ______ this dictionary belongs to
---Let me see. Oh, it’s __________.
A. who does, mine B. who, me
C. whose, mine D. who, mine
【解析】句意为“—你知道这本词典是谁的吗？—我看看。哦，是我的”。belong to后面应该加“某人”，而不是加“物主代词”，所以第一个空用who；名词性物主代词mine想当于my dictionary。
D
--- Whose bike is this
--- It must _______ Adam’s. Look! His bag
is on it.
A. belong to B. be C. is D. to be
【解析】must 后接动词原形，排除C项；“be + sb.’s”意为“是某人的”。
B
The CD might belong to John. (同义句)
2) The schoolbag belongs to Tom. (对划线部分提问)
The CD might be John’s.
Who does the schoolbag belong to
2. Whose book is this
whose adj. 谁的
No one knows whose dictionary this is.
无人知道这是谁的字典。
Whose sweaters are these
这些是谁的毛衣？
whose 用来对物主代词及名词所有格进行提问：
1)．提问形容词性的物主代词。
These are my bananas.
→ Whose bananas are these
2)．提问名词性的物主代词。
That bedroom is mine.
→ Whose is that bedroom
Hers are in the classroom.
→ Whose are in the classroom
知识链接
3)．提问名词所有格(不包括of构成的所有格)
Those are the twins’ bags.
→ Whose bags are those
Tom’s mother is a good teacher.
→ Whose mother is a good teacher
4). whose 可针对 my、your、our、their、Kate’ s 等形容词性物主代词提问
— Here is a schoolbag. Whose is it
— Oh, it’s_________. Thank you.
A. my B. mine C. me
【解析】my为形容词性物主代词意为“我的”；mine为名词性物主代词意为“我的”；me为人称代词的宾格意为“我”。名词性物主代词相当于形容词性物主代词+名词。此句的答语句意为：它是我的书包，回答Whose提问，因此需要用mine代替my schoolbag。
B
— Dad, ______ is my mp4
—It’s in your desk.
A. where B. what C. whose
－ _______ bag is this
－ It’s hers.
A. Who B. When
C. Whom D. Whose
A
D
who’s和whose的用法
who’s ＝ who is，意思是“谁是”，who可以作主语、宾语或表语;
whose意思是“谁的”，可以作定语、也可作表语，放在名词前，如：
Whose desk is this
= Whose is this desk

动词填空
用括号内所给动词的适当形式填空。
It was a pity that you _____________ (not attend) the meeting last Friday afternoon.
didn’t / did not
attend
attend, join, join in, take part in都有“参加”的意思。区别是：
attend主要指“到场”或“出席”会议、宴会、典礼、仪式等。
join指参加某团体或组织成为其中一员或参加活动,是非正式用语。
join in表示“加入；参加(某种活动)”，in之后接名词或v.-ing形式；表示“参加某人的某种活动”时，可用join sb. in (doing) sth. 。
take part in指参加一项工作, 在其中分担一部分, 也指参加活动并积极工作。

根据所给汉语完成下列句子，每空词数不限。
你的建议对我很有价值，值得采纳。
Your advice is _________________ to me. It is worth taking.
解析：习惯用法“be +of +名词 = be +名词的形容词形式”。
of great value / (very) valuable
5. I think somebody must have picked it up.
must have picked it up是“must + have + 过去分词”的结构，表示对过去时间里可能发生的事情的推测，语气较强，具有“肯定”的意思。
--- Linda has gone to work, but her bicycle is still here.
--- She must have gone by bus.
You must have mistaken her for her sister.
你一定是把她误认为是她的姊妹了。
情态动词+have+过去分词
may (might) have + done sth. / can (could) have + done sth.，表示过去，推测过去时间里可能发生的事情。
ought to have done sth., should have done sth. 本应该做某事，而事实上并没有做。否定句表示“不该做某事而做了”。
You ought to (should) have been more careful in this experiment.
ought to 在语气上比should 要强。

I can’t find him anywhere; he ______ home.
A. can go B. can have gone
C. could go D. could have gone
解析：can一般不用于肯定的推测用法中，从而排除A、B；另一方面，从句意上看，这应该是对过去发生动作的推测，所以只能用D。
D
