I've made a lot of friends since I joined the tennis club.

问题描述:

I've made a lot of friends since I joined the tennis club.
选择与joined意思最相近的词语
A joined in B became a member of C took part
选对加钱

B became a member of
加入某个组织,团体,成为其中的一员用join,等于 become a member of  可是其他的也是加入的意思为什么不对join in 和take part in 一般指“参加(活动)”
