问题补充：
The news that volunteer workers will go to homes for the aged now.
A. is being talked about
B. are being talked about
C. is being talked
D. are being talked
答案：
(答案→)A. is being talked about
B. are being talked about
C. is being talked
D. are being talked
解析：考查主谓一致和时态：句意：自愿工作者将进入养老院的消息正在被讨论。主语是the news，是不可数名词，所以谓语是单数，而且talk是不及物动词，讨论某事“talk about sth”，选A。
