我试着说我的思路吧，供参考
A/B:
如果没有"they are"，看上去"be able to"像是针对主语household labor，这显然illogical.
另外(a minor point)，我感觉miracle和be miraclous意思上有点小区别，你体会一下英文释义, appliance被当作a miracle是不是太夸张了？"appliance that sb. would find miraculous"说得通。类似这样的同样词根的形容词-名词的意思上的细微差别，英语里有很多。
E: be able to后面没动词，错大了，别的我不看了
D: 个人觉得最明显的错误是时态，"could"和前面的"remains"不匹配。要知道"although"这词的意思，然后你就知道，要不前后都是虚拟语气，要不就都是indicative mode，总之不可能前面indicative后面subjunctive。
从逻辑含义上看，应该用even if，而不是although
C后半句用虚拟语气，我认为作者想说，这些appliance也许在grandparents那个年代根本就不存在。假如说放在那时，grandparents会觉得miraculous。其实这题时态上关键的突破点还不在于后面的虚拟语气（因为，假如这些appliance在那个历史年代存在，而grandparents确实认为miraculous，就不该用虚拟语气），而在于前面必须用can afford和remains匹配。
另外FYI，GMAT一般prefer "can" to "be able to"，原因：
1. Concision. 一个词能代替3个词，何乐而不为？
2. 有些时候只能用can，而不能用be able to。典型的是，对于non-living things
For many people, household labor remains demanding even if able to afford household appliances their grandparents would find a miracle.
A. even if able to afford household appliance their grandparents would find a mirale B.despite being able to afford household appliance their grandparents would find a miracle C.even if they can afford household household appliance their grandparents would have found miraclous
D.although they could afford household appliance their grandprerants would find miraculous E.Even if they are able to household appliance which would have been a miracle to their grandparents 为什么这道题选C的呢？还有C的后半句为什么要用虚拟语气的呢 -- by 会员 浅浅123 (2012/1/29 22:44:55)
