阅读理解。 I was 9 years old when I found out my father had AIDS. AIDS wasn't something we talked about in my country when I was growing up. From then on, I knew that this would be a family secret. When I was 12, his condition got worse. We couldn't afford all the necessary medications for him, and because Dad was unable to work, I had no money for school supplies and often couldn't even buy food for dinner. I would sit in class feeling completely lost, not knowing what the teacher was saying. I did not share my burden (负担) with anyone. When my father was moved to the hospital, the nurses would leave his food on the bedside table even though he was too weak to eat by himself. I knew he was going to die, but after so many years of  keeping his illness a secret, I completely know what to do when he reached his last days. I was 15 when my father died. He took his secret away with him, having never spoken about AIDS to anyone, even me. 1. What does 'his condition got worse' mean in Chinese? A. 他的条件得到了改善. B. 他的情况更加恶化了. C. 他变得越来越坏了. D. 他的环境变得更坏了. 2.
