问题描述：
julia,linda and rose are both my pen pals 改错
it spends me so much time to do homework改错
can you tell me what it mean改错
答
both改all
spends改takes
mean改means
答
both改all 三者用all
spends改takes It takes sb some time to v sth.
mean改means it 为单数
答
both适用于二者,all用于3者或3者以上,所以both改成all
spend的主语是人,将spend改为take
mean改为means（what it means为宾语从句,用陈述句,2楼是错的）
