167.(Neanderthals had a vocal tract that resembled those of the apes) and so were probably without language, a shortcoming that may explain why they were supplanted by our own species.
(A) Neanderthals had a vocal tract that resembled those of the apes
(B) Neanderthals had a vocal tract resembling an ape’s
(C) The vocal tracts of Neanderthals resembled an ape’s
(D) The Neanderthal’s vocal tracts resembled the apes’
(E) The vocal tracts of the Neanderthals resembled those of the apes
答案：B
that作为同位语,前面应该要有一个明确的指代词吧,但是找不到呀!!!莫非同位语也可以指代一句话were probably without language了么?如果这个解释是对的话，这句话就我打破了我之前认为同位语必须有名词的结构对应的想法。还是说把同位语就当成一个名词来用,用一个名词来指代之前的一句话么? |
