选择：Many things () impossible in the past are quit common today.A having been consideredB to be consideredC consideringD considered为什么要选它?请翻译?
选D,因为这是一个简单句,只能有一个谓语,Many things 是主语,are是谓语,common 是表语应该.considered impossible in the past 是做Many things 的后置定语,意思是说,过去许多被认为不可能的事情现在都很平常了.B表示将来不选,C表示主动,不是这件事认为,而是这件事被认为
in the past 要用一般式,不选A
这里其实可以改成一个定语从句；Many things that was considered impossible in the past are quit common today
D
过去时态.
许多在过去认为是不可能的事情,在今天看来是那么的平常.
D 被动语态！晕
被认为是不可能的事情。 在这里也可以认为是 做形容词用。
D 因为是过去式,所以要用 -ed
很多事情从前被认为不可能，现在却很常见。
被动语态，所以选D
are前面完整的表述应该是
Many things were considered impossible by us in the past。
