other和others，give in和give up在用是老是混不清，请兄弟姐妹帮忙理清理清

other能当形容词，用于修饰名词；others是代词，可以放在名词放的地方，也就是other xx=others
当给明了范围（比如一个班级，一家人，一筐东西……）的时候，范围内之后两个时指另一个可以用the other，特指另一个,就是：Two apples,xiaoming takes one, the other is taken by xiaohong. ；范围内有多个而且其他的东西是复数的时候可以用others指代，就是：Three apples, xiaoming takes one,others are taken by xiaohong.

give in
屈服; 投降; 让步
The defenders were outnumbered and had to give in.
抵抗者寡不敌众, 只能投降。
give up是放弃，是主观意识驱使的，give in是被迫的
