Where____livebeforeyoucamehere?A?
Where____live before you came here? A did you use to B did you us to C use he to D he used to
首先,先对两个有use或us的短语进行区别. use to do...过去经常做... be/get used to doing...习惯做... 如果是use to do, 那疑问句中就是Did he use to get up later? 反问句中He used to get up later,didn't he? 如果是be/get used to doing, 疑问句Is he used to getting up later? 反问句中He is used to getting up later,usedn't he? Where____live before you came here? A did you use to B did you used to C use he to D he used to 显然,该句的答案中的B、C、D的形式不对。B中助动词did提前，used应用原形use。C中疑问句需要用助动词。D中使用陈述语序错了，而且也没有使用助动词提前。所以答案是A。
