按你提供的The girl wondered what he often ___(talk)about.,应该填talked
因为前面wondered是过去式,后面就要一致,也用过去式.
但是 What does he often talk about?The girl wonderes.改为复合句的话,应该是
The girl wonderes what he often talks about.
因为 wonders 是一般现在时态,用了三单形式,加s
所有矛盾了,应该有个地方出错了,请检查清楚是啊是啊 我也在犹豫 到底用三单还是用过去式你还是按照The girl wondered what he often ___(talk)about 这个来填，肯定没错。wondered，后面对应 talked
