大全672

672。 Students in the metropolitan school district lack math skills to such a large degree as to make it difficult to absorb them into a city economy becoming ever more dependent on information-based industries.

(A) lack math skills to such a large degree as to make it difficult to absorb them into a city economy becoming

(B) lack math skills to a large enough degree that they will be difficult to absorb into a city’s economy that becomes

(C) lack of math skills is so large as to be difficult to absorb them into a city’s economy that becomes

(D) are lacking so much in math skills as to be difficult to absorb into a city’s economy becoming（E）

(E) are so lacking in math skills that it will be difficult to absorb them into a city economy becoming

请问d那里错了？

  so A that B可以不一致，见http://forum.chasedream.com/dispbbs.asp?boardID=23&ID=93635&page=3

中第67条解释

B be so as to do sth 只用于当 do sth的逻辑主语和句子主语（i.e., B here）一致时。D选项说Students are lacking so much in math skills as to (students) be difficult to absorb into a city’s economy becoming...，相当于说"students are difficult to absorb..."，这就像说"I am difficult to fly."一样unidiomatic. 正确的说法是：It's difficult for me to fly.

638、sec07-24 Several years ago the diet industry introduced a variety of appetite suppressants, but some of these drugs caused stomach disorders severe enough to have them banned by the Food and Drug Administration.

(A) stomach disorders severe enough to have them

(B) stomach disorders that were severe enough so they were

(C) stomach disorders of such severity so as to be

(D) such severe stomach disorders that they were（D）

(E) such severe stomach disorders as to be

再问问，so as to用于简单结构，是指简单句吗？象这题的主从句是不是就不在这个范畴内，所以e才不对的？

有such as to吗？

672.D從邏輯關繫看，至少應該是students be difficult to be absorbed，但這種說法好像不如it is difficult to absorb students

638.E，好像沒有such ... as to吧？至于so ... as to do，用于簡單結搆，我的理解：sth. be so adj. as to do，這種用法好像通常是對的（隻要沒有邏輯問題），其他情況我沒把握，好像adj.換成一長串復雜的結搆，通常就是錯的，這個還有待驗證

有such as to吗？
