逗号前是让步状语从句,不过进行了省略,还原后应为:Though
they
(Andy
and
Ruby)
were
tired
and
short
of
breath,句子的主语是Andy
and
Ruby,所以应该用“感到疲劳的”,即要用tired;又由于是与形容词短语short
of
breath相并列,所以应选形容词tired,不选to
be
tired或Being
tired。
你好。答案只能是A==Andy and Ruby , WHO WERE tired and short of breath, were the first to reach the top of Mount Tai.
你的句子是一种分词结构,是从让步状语从句变来的:Though they were tired and out of breath, Andy and - - - - . 在分词结构的句子里面,原来从句部分的主语they和谓语动词were 被去掉了,连接词though也被去掉了。
