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。如：

2. Well, where did you last put it
last adv. 上次; 最近的一次; 最后一次
last除用于句末外, 还常置于句子中间。
e.g. When I last saw her, she was working in Shanghai.
我上次见她时, 她在上海工作。
When did you see him last

3. I attended a concert yesterday so it might still be in the music hall.
辨析 join/take part in/attend
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
e.g. Will you join us in the picnic 你参加我们的野炊吗？
join in多指参加小规模的活动如“游戏, 比赛”, 口语中常用。
e.g. Join in the basketball game. 参加篮球赛。
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. We’ll take part in the sports meeting/club.
take an active part in 积极参加……
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。
句子主语只是去听, 去看, 自己不一定起积极作用。
e.g. I attended a night school. 我上夜校。
4. 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”这样的意思。
e.g. He’s playing outside. He must have finished his homework.
5. I’ll call them now to check if anybody has it.
anybody pron. 任何人
常用于否定句或疑问句中; 当用于肯定句中时, 相当于any person, 意为“任何
人”。
e.g. I will not tell anybody the secret.
Is there anybody in the office
Anybody could do it!
