When I think about teenagers in Africa and South America,( )don't have all of those things
A they B who C which D that
When I think about teenagers in Africa and South America,( )
B
理由 非限定性定语从句,先行词是人,因此用who
再问: A 呢
再答: 如果两句中间是句号,就必须是A,因为两个句子独立了,只能用they代替提到过的人; 现在的状况是逗号出现,说明两句并未独立,那就得分出个主从来。they不是从句的关系词,所以不可以。
