1.、It must belong to Carla.
belong to 意为“属于”，它一般不用于进行时态和被动语态。
此外，belong to sb. 通常可以和名词性物主代词或名词所有格(一般是’s 所有格)互相转换。
辨析join / join in / take part in /attend
2、I attended a concert yesterday so it might still be in the music hall.
join 指加入某个党派, 团体组织等, 成为其中一员, 意为“ 参军, 入党, 入团 ”。
e.g. join the Army/the Party/the League
join sb. in (doing) sth. 和某人一道做某事
join in 多指参加小规模的活动如“游戏;比赛”, 口语中常用。
take part in 指参加会议或群众性活动, 着重说明主语参加该项活动并在活动中发挥作用。e.g.take an active part in 积极参加……
attend attend 正式用语，vt. 指参加会议, 婚礼,
葬礼, 典礼; 去上课, 上学, 听报告等
e.g. Will you join us in the picnic 你参加我们的野炊吗？
Join in the basketball game. 参加篮球赛。
We’ll take part in the sports meeting /club. 我将参加运动会/俱乐部。
I attended a night school. 我上夜校。
He’s playing outside. He must have finished his homework.
他在外边玩，一定已经把作业做完了。
3、I think somebody must have picked it up.
must在此处表示推测, 意为“一定”。英语中当情态动词后接have done时, 表达对过去的事情进行推测, 故must have done something表示“过去一定做过了…” 。
情态动词 用法 例句
must 表示很有把握的推测，意为“一定”，只用于肯定句。 The light is out. He must be sleeping.
could 和might 表示不太有把握的推测，意为“可能”。 The pen could / might be Joe’s. I saw it on his desk just now.
can’t 表示很有把握的否定推测，意为“不可能”。 The girl here can’t be Helen. Helen has gone to Beijing.
e.g. I will not tell anybody the secret.
Is there anybody in the office
Anybody could do it!
5、I’ll call them now to check if anybody has it.
anybody pron. 任何人
【注意】
anybody常用于否定句或疑问句中;
当用于肯定句中时, 相当于any person, 指“任何人”。
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？
6、Whose book is this
whose adj. 谁的
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
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
whose adj. & pron. 谁的
who pron. 谁
whom pron. 谁(宾格)
e.g. ---Whose volleyball is this --- It must be Carla’s.
