題都來自于og，都是我自己總結的，希望大家有這方面的問題和好的語法解釋都往上貼，可以加深對平行對稱結構的理解：

og－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

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

(E) every thirty-two pupils now has one microcomputer, four times as many as

這里as后面跟的是句子，從句的賓語就是as many （computers）as中的computer

132. According to a study by the Carnegie Foundation for the Advancement of Teaching, companies in the United States are providing job training and general education for nearly eight million people, about equivalent to the enrollment of the nation’s four-year colleges and universities.

(A) equivalent to the enrollment of

(B) the equivalent of those enrolled in

(C) equal to those who are enrolled in

(D) as many as the enrollment of（E）

(E) as many as are enrolled in

這里as后面跟的是句子，從句的主語就是as many （people）as中的people

156. Dirt roads may evoke the bucolic simplicity of another century, but financially strained townships point out that dirt roads cost twice as much as maintaining paved roads.

(A) dirt roads cost twice as much as maintaining paved roads

(B) dirt roads cost twice as much to maintain as paved roads do

(C) maintaining dirt roads costs twice as much as paved roads do

(D) maintaining dirt roads costs twice as much as it does for paved roads（B）

(E) to maintain dirt roads costs twice as much as for paved roads

這里as后面跟的是句子，從句的賓語就是as much （money）as中的money

187. In one of the bloodiest battles of the Civil War, fought at Sharpsburg, Maryland, on September 17, 1862, four times as many Americans were killed as would later be killed on the beaches of Normandy during D-Day.

(A) Americans were killed as

(B) Americans were killed than

(C) Americans were killed than those who

(D) more Americans were killed as there（A）

(E) more Americans were killed as those who

這是一個比較特別的例子

我是這么理解的：句子主謂賓在的在as－as 結構中，強調four times，第一個as引導的句子的主語與第二個as引導的主語比較，第二個省略

198. Although Napoleon’s army entered Russia with far more supplies than they had in their previous campaigns, it had provisions for only twenty-four days.

(A) they had in their previous campaigns

(B) their previous campaigns had had

(C) they had for any previous campaign

(D) in their previous campaigns（E）

(E) for any previous campaign

？A is more -----than b

a,b 應該是相同的成分

這個句子，不理解，than的后面應該也是出現相同的比較成分，如果補全是supllies for any previous campaign，這樣不是有點不平行的問題嗎？

253. Analysts blamed May’s sluggish retail sales on unexciting merchandise as well as the weather, colder and wetter than was usual in some regions, which slowed sales of barbecue grills and lawn furniture.

(A) colder and wetter than was usual in some regions, which slowed

(B) which was colder and wetter than usual in some regions, slowing

(C) since it was colder and wetter than usually in some regions, which slowed

(D) being colder and wetter than usually in some regions, slowing（B）

(E) having been colder and wetter than was usual in some regions and slowed

the weather 和 usual 是兩個不對稱的，可以進行比較嗎？
