对的（多了个while)we went to climb the hill ,while my father remained at home 后面是while 引出的另一分句,表对比的.既然是个句子,不可改为非谓语动词remaining很高兴为您解答,fightout为您答疑解惑如果本题有...什么时候可以换呢 请举例你是说换为非谓语动词？这样你就不能用连词while (因为while 的句法功能就是引出句子的）你可以用with 复合结构， 这样改：we went to climb the hill ,with my father remaining at home或者用独立主格结构：we went to climb the hill ,my father remaining at home
