我在题目中给答案了，我要的是解释，各位英语高手，帮帮忙啊，谢谢啦！！！
2意思是没有一家旅馆可以和这家相比的，有比较的意思的就是CD，compare是用于两者之间的比较的·如，compar A with B.所以就选D.
3B是现在完成时，指四年前完成了结婚这件事，A则表示动作
4前面已经用了are，是指被动的，问题容易被解决，这个句子你读一下就感觉是B比较顺。
题目太多啦~一一解答太麻烦了，有些题目就凭感觉，也不说不怎么清楚，你问同学比较快和清楚啦~~
2.a.成为 b.打败 c.比较，对比 d.比得上
3.A.married;engaged时态一样了，很明显他结婚的时间和订婚的时间是不一样的 B.has been married to;was engaged to 正确。four years ago是过去时，那么前面的结婚时态就要与之搭配用现在完成时。
