【答案】They often talk __________ their homework in the afternoon.

They often talk __________ their homework in the afternoon.

A.to B.with C.about D.of

【答案】

C

【解析】

句意：他们经常在下午谈论他们的家庭作业。

考查介词辨析。talk to sb.和某人交谈，强调一方对另一方说；talk with sb.与……交谈，强调互相交谈；talk about sth.谈论某事；talk of谈到(用于引出新话题)。设空处后面their homework（他们的家庭作业）是物，根据句意语境，可知talk about符合句意，故选C。
