join in是个词组,表示“参加,加入”,没有英美式之分。但这个词组和join,take part in有一点区别。join,join in和take part in1)加入某党派、某组织或某社会团体,用join,不可用join in。如:He will never forget the day when he joined the Party.他永远也忘不了他入党的那一天。join还可解释为“连接”。如:The railway joined the two cities.铁路把两个城市连接起来了。2)说参加某种活动用join in,如说“与其人一起做某事”,则用join sb. in sth. / doing sth. 。如:May I join in the game? 我可以参加这个游戏吗?join in多指参加小规模的活动如“球赛、游戏”等,常用于日常口语。如:Come along, and join in the ball game. 快,来参加球赛。3)take part in参加(群众性活动、会议等),往往指参加者持积极态度.起一份作用。如:We are going to have an English evening. Do you want to take part?我们准备举办一个英语晚会,你想参加吗?
区别是:join指加入某个党派,团体组织等,成为其成员之一,意为:“参军、入团、入党”等。和某人一道做某事,其结构为:join sb. in (doing) sth.join in多指参加小规模的活动如“球赛、游戏”等,常用于日常口语。take part in 指参加会议或群众性活动等,着重说明句子主语参加该项活动并在活动中发挥作用。attend是正式用语,及物动词,指参加会议,婚礼,葬礼,典礼;去上课,上学,听报告等。句子的主语只是去听,去看,自己不一定起积极作用。例句辨析:join1、His wife and children moved to join him in their new home.他的妻子和孩子们搬进了他们的新家,和他一起生活。2、He joined the Army five years ago. 他5年前参军了。join in1、I hope that everyone will be able to join in the fun.我希望每个人都能够加入进来,玩得开心。2、He started to sing and I joined in. 他开始唱起歌来,然后我也跟着唱起来。take part in1、They returned to take part in the season's opening game. 他们回来参加本赛季的开幕赛。2、You don't need strength to take part in this sport.参加这项运动不需要太多体力。attend1、There are more pressing matters to be attended to today. 今天有更紧急的事情要处理。2、The main thing is to attend to the injured. 首要任务是照顾伤者。
