it deals with the lexicon knowledge of the word achieve
simply, per capita consumption cannot "achieve" 19 pounds a year, 'cause 19 pounds a year is not an objective, rather a fact, required by the verb "achieve"

以下是引用yzlinlin在2003-11-6 4:03:00的发言：
20.  According to the National Pasta Association, per-capita consumption of pasta in the United States, which has already been approaching 19 pounds a year, will achieve 30 pounds a year by the twenty-first century.  
(A) According to the National Pasta Association, per-capita consumption of pasta in the United States, which has already been approaching 19 pounds a year, will achieve 30 pounds a year by the twenty-first century.  
(B) Already approaching 19 pounds a year in the United States, the National Pasta Association predicts that per-capita consumption of pasta will reach 30 pounds a year by the twenty-first century.  错在approaching的逻辑主语
(C) The National Pasta Association predicts by the twenty-first century that per-capita consumption  of pasta in the United States, which is already approaching 19 pounds a year, will achieve 30 pounds a year.  错在改变了状语位置而引起歧义 by the twenty-first century 还有achieve
(D) By the twenty-first century, the National Pasta Association predicts that per-capita consumption of pasta in the United States, having already approached 19 pounds a year, will reach 30 pounds a year.  错在改变了状语位置而引起歧义 by the twenty-first century 还有having错
(E) According to the National Pasta Association, per-capita consumption of pasta in the United States is already approaching 19 pounds a year and will reach 30 pounds a year by the twenty-first century.  

答案E。问题有3：
1，A为什么不对？或说为什么现在的状况19 pounds 不用现在完成时，而是进行时？唉，时态的判断----我不变的软肋。

2，答案E难道没有改变句子重心的嫌疑吗？在我看来，划线部分主要想阐明will ......。而答案E却用平行的2个单句来平分秋色，合适吗？

3，选项C的that如果放在predicts 后面的话，是否也对，甚至优于E？
