Question

【题目】The twins are talking about the book Who Moved My Cheese. It's fun to _______ them.

A. join B. join in C. take part in D. enter

Answer 1

【答案】A

【解析】句意：这两个双胞胎正在谈论《Who moved my Cheese》这本书，加入到他们的谈论很快乐。

join“加入某团体或某人”，join in多指参加活动，take part in指参加会议或者群众性的活动等，重在说明句子的主语参加该项活动并在活动中发挥作用，enter-进入，故答案选A。
