问题描述:

( )It's meaningful _______children_______charity work at a young age.
A.of; to join in B.for;to join in C.of;joining D.for;to join

正确答案为:
D for to join
对于孩子们来说,年轻时参与到慈善工作中去很有意义.答案是B,我本来也选D嗯 我特地去查了一下 join, join in 的区别

本题是 charity work, 需要用 join in
如果是单独 charity, 就用join

join+团体
join in + 活动

所以是选B
