解答
同学,很高兴回答你的问题正确答案:haven't they即:The Greens must have been to Shanghai,haven't they?翻译:格林一家人原来一定去过上海,不是吗?解析:当must用来表示对过去的情况进行“推测”(must + have do...那weren‘t they 可以用么?不可以,因为前面的陈述句中没有were,所以后面的疑问部分不能weren't 提问。为什么额,这是12年安徽江南十笑一个题,当时只有abcd四个选项,答案给的是d,我一直弄不明白哦,我才仔细看了一下,D选项是weren't,这就是说强调对过去事情的推测,反意疑问句部分要用“didn’t + 主语”或“wasn't/weren't + 主语”,本句虽然没有明显的过去时间状语,但是也是表示对过去的推测。
