The blue jacket belongs to him / Jerry. →
The blue jacket is his / Jerry’s.
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. 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。

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
