选D
这里考的是 wish 的虚拟语气用法 由于是表示与将来事实相反,所以 用could go　　wish 的虚拟语气用法是什么？？帮我讲一下，谢谢！！你好: 1. 表示现在或将来的愿望,从句中过去式.　　I wish I knew his address.　　I wish I were young.2. 表示过去没有实现或不可能实现的愿望, 从句用过去完成式或would, could, might + have + 过去分词.　　I wish you had written to him. I wish I could have slept longer this morning, but I had to get up and come to class.3. 如果将wish改成wished, 其后that 从句中动词的形式不变.4. 如果that 从句中用would , 一般表示 对现状不满或希望未来有所改变或请求　　I wish he would answer my letter.　　I wish prices would come down.　　I wish you would help me.　　I wish you would stop asking silly questions.你讲的真好，太谢谢你了！！我再请教你一道题“Life is like walking in the snow”,Granny used to say , "because every step__"A.has shownB.is showingC.showsD.showed谢谢你好;选 B 翻译: "生活就像在踏雪" , 外婆常说, "因为每一步都在表演(展示)"为什么不选B，表示动作未完车，还要持续下去，就是脚步还要持续下去我就是选的 B 只有B合适 (因为这里是 现在分词showing作表语 其他的ACD 都不能单独放在becauseevery step后面)
