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

The sentence requires a subject appropriate to both members of a compound predicate, the second member being and so were probably without language. B, the best choice, logically uses Neanderthals as the subject. Choice A also uses this subject, but the plural pronoun those does not agree with its singular antecedent, (A是否还漏了如下错误？即造成误解and so were与resembled平行)a vocal tract. C, D, and E present the inappropriate subject vocal tracts, which cannot logically govern the second member of the predicate (i.e., vocal tracts cannot be said to be without language). Moreover, it is better to use the singular in referring to an anatomical feature common to an entire species; C, D, and E use the plural vocal tracts. D compounds the problem by giving multiple vocal tracts to one Neanderthal.

89. A recent national study of the public schools shows that there are now one microcomputer for every thirty-two pupils, four times as many than there were four years ago.

(A)  there are now one microcomputer for every thirty-two pupils, four times as many than there were

(B)  there is now one microcomputer for every thirty-two pupils, four times as many than there were

(C)  there is now one microcomputer for every thirty-two pupils, four times as many as there were（前面是is,这儿为什么用were?）

(D)  every thirty-two pupils now have one micro­computer, four times as many than there were

(E)   every thirty-two pupils now has one microcom­puter, four times as many as（为什么这儿不是省略？）

Choices A, B, and C appropriately use the construction "one X for every thirty-two Y's" to describe the ratio of computers to pupils, but only C, the best answer, is error-free. In A, are does not agree with the subject, one microcomputer; furthermore, in A, B, and D, than is used where as is required. Choices D and E reorder and garble the "one X ..." construction, making four times as many refer illogically to pupils.

92. Never before had taxpayers confronted so many

changes at once as they had in the Tax Reform Act of 1986.

(A)  so many changes at once as they had in

(B)  at once as many changes as

(C)  at once as many changes that there were with

(D)  as many changes at once as they confronted in

(E)   so many changes at once that confronted them in

D中改为as they did in the Tax Reform Act of 1986行吗？
