Someone wants to be a doctor.Someone wants to be a basketball player because they are good at spor

问题描述:

Someone wants to be a doctor.Someone wants to be a basketball player because they are good at spor

有人想当医生.有人想当篮球运动员,因为擅长运动.
语法有错,后面because they are good at spor
应该用:because (he is) good at sports.
因为someone是有人,是单数概念,指代用he/his/him,不用they are
