——————aids had left a scar on Ajani and his sister ,their grandfather's face turned
white.
a when he heard b having heard c when hearing d on hearing
答
答案是A
B,C和D在逻辑上都是错误的,因为face这个主语是不能hear什么的.只有从句（when he heard ------,their grandfather's face turned white）才能弥补这样的逻辑错误.
又如：When the boys were playing baketball,their girl-friends were watching them.(这句是对的),但如果变成了-----Playing baketball,their girl-friends were watching them,条理就乱了：到底是谁在playing basketball?你的句子也就是这样的条理问题.你的解释我看明白了， 请教一下，when he heard aids had left a scar on Ajaniand his sister 是什么意思，可以翻译吗?当他听到，艾滋病病毒在 Ajani 和his sister身上有感染时，爷爷脸色变白了谢了哦，you are welcome
