 ♣ join, combine, connect, unite
　参见connect条。
 ♣ join, attend, participate, take part in
　这组词（组）都可作“参加”解。其区别是：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。attend主要指“到场”或“出席”会议、宴会、典礼、仪式等。例如：
　He never attended a funeral.　他从不参加丧礼。
　participate　是不及物动词，后接in，指参与活动并积极从事工作，是正式用语。例如：
　I'll try to follow your advice about participating in students' activities.　我尽量遵照你的劝告，参加学生的活动。
　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。例如：
　I'm not going to take part in arguments.　我不打算参加辩论。
 ♣ join in, take part in
　两者都可作“参加某项活动”解。其区别是：
1. 参加人（即主语）的身份不一样：take part in指以主办人或发起人的身份参加某项活动，而join in则是以成员身份参加。
2. 在活动中起的地位不一样：take part in强调“发挥作用”，做主角，而join in则含有“平等”的意味。
3. 这两个词在搭配范围上也有差别：“参加工作、会议”自然要在其中发挥作用，要以主人翁姿态，所以一般用take part in；而“参加比赛、讨论”，作为“普通参加者”参加，就要用join in了。

1. 他参军两年了。
　［误］ He's joined the army for two years.
　［正］ He joined the army two years ago.
　［正］ It is two years since he joined the army.
　［正］ He's been in the army for two years.
　［析］ join是瞬间动词，在完成时态中不能跟表示一段时间的状语连用。
2. 我们加入了乡村俱乐部。
　［误］ We joined in the country club.
　［正］ We joined the country club.
　［析］ 说“加入党派、团体、学会等组织”用join，不用join in；说“加入游戏、讨论等活动”用join in，不用join.

4. 客户纷纷来函希望参加广交会。
　［误］ The clients wrote to us one after another to join the Guangzhou Fair.
　［正］ The clients wrote to us one after another to attend the Guangzhou Fair.
　［析］ 客户参加广交会并不是成为其成员，而是为了洽谈业务，故应改为attend，表示“出席”“到场”。
5. 他听到同学们在唱歌，便走过去一起唱起来。
　［误］ When he heard his classmates singing, he went over and took part in.
　［正］ When he heard his classmates singing, he went over and joined in.
　［析］ 短语take part in中的in是介词， in后须接宾语，故不可置于句末。而join in中的in可以是介词，也可以是副词，作副词时可以置于句末。
6. 你愿不愿和她一起参加这场比赛?
　［误］ Will you join her in the game together?
　［正］ Will you join her in the game?
　［析］ join表示“参加”，已含有“一起”的意思，不可再用together修饰。

　［反义词］ alienate, dissociate, separate, sever
　［词源］　古法语joindre <拉丁语jungere（连接在一 起）
