Liu Jaiyu, a 94-year-old former English teacher, has found herself no longer able to speak Chinese after parts of her brain relating to native language were damaged by a cerebral infarction, the local Hunan TV reports . Television pictures show her in bed, answering simple questions in English, which means the nursing staff are having to brush up on their language skills. "She greets me in the morning using English, after she's eaten her meals in the afternoon she uses English," one nurse tells the TV. "My memory of the language isn't too good, sometimes I don't understand what she's saying!"
