　　意;使用other將market for paper排除在外,表達出market for paper和other market的對比關系

　　(C)第一個it指代模糊,既可能指代paper production又可能指代use of wood,如果根據優先原則指代use of wood則不符合邏輯;第二個it錯誤同A選項

　　(D) its的指代錯誤同C的第一個it; all后面應該加other將它自身排除在外才能表達兩者間的對比關系

　　(E) its錯誤同D選項; it錯誤同A選項

　　12. Industrialization and modern methods of insect control have improved the standard of living around the globe while at the same time they have introduced some 100,000 dangerous chemical pollutants, having gone virtually unregulated since they were developed more than 50 years ago.

　　(A) while at the same time they have introduced some 100,000 dangerous chemical pollutants, having

　　(B) while at the same time introducing some 100,000 dangerous chemical pollutants that have

　　(D) but introducing some 100,000 dangerous chemical pollutants at the same time that have

　　(A)第二個they有指代不清的嫌疑,既可能指代第一個they所指代的Industrialization and modern methods of insect control又可以指代chemical pollutants;句尾的分詞結構having gone…目的是作pollutants的后置定語，但有作狀語的歧義存在。

　　(B)正確,使用sb do… while doing結構, 省掉了they, 避免了同第二個they產生指代不清的嫌疑;使用限定性定語從句符合邏輯意思

　　(C)使用which作非限定定語從句,導致邏輯錯誤,表明所有的chemical pollutants都 have gone virtually unregulated; 第二個they有指代不清的嫌疑

　　(D) but introducing不能和have improved構成并列

　　(E) but… introducing不能和have improved構成并列; 句尾的分詞結構having gone…目的是作pollutants的后置定語，但有作狀語的歧義存在。

　　13. Officials at the United States Mint believe that the Sacagawea dollar coin will be used more as a substitute for four quarters rather than for the dollar bill because its weight, only 8.1 grams, is far less than four quarters, which weigh 5.67 grams each.

　　(D) as a substitute for four quarters more than the dollar bill because its weight of only 8.1 grams is far lighter than it is for

　　(E) as a substitute more for four quarters rather than for the dollar bill because its weight, only 8.1 grams, is far less than it is for

　　(A) more… rather than搭配錯;its weitht 和后面 four quarters 比較對象不對等。
