The overall key finding of our study is that the patient in Africa receiving antiretroviral therapy for HIV can expect to live a near-normal lifespan上句中that后面为什么直接用receiving这种形式?不应该是whoisreceiving吗?

两者均可.
who is receiving 使用了定语从句,而用receiving 是直接选用现在分词做定语,因为patient与receive之间是主动关系,所以用了-ing形式.有些题如果是被动关系,要使用-ed 形式.
