37. (26400-!-item-!-188;#058&003135) 句子结构，逻辑表达
Using technology as new as space-age fabrics and as ordinary as common dry-cleaning chemicals, scientists and historians, in their attempt at cleaning and preserving the American flag that flew over Fort McHenry in Baltimore in 1814, are hoping that it will then last another 200 years.
(A) and as ordinary as common dry-cleaning chemicals, scientists and historians, in their attempt at cleaning and preserving the American flag that flew over Fort McHenry in Baltimore in 1814, are hoping
(B) and as ordinary as common dry-cleaning chemicals, scientists and historians are attempting to clean and preserve the American flag that flew over Fort McHenry in Baltimore in 1814, hoping
(C) and as ordinary as common dry-cleaning chemicals, an attempt by scientists and historians to clean and preserve the American flag that flew over Fort McHenry in Baltimore in 1814 is being made in the hope
(D) but also as ordinary as common dry-cleaning chemicals, scientists and historians who are attempting to clean and preserve the American flag that flew over Fort McHenry in Baltimore in 1814, hoping
(E) but also as ordinary as common dry-cleaning chemicals, an attempt by scientists and historians at cleaning and preserving the American flag that flew over Fort McHenry in Baltimore in 1814 in hopes
答案是B，
我选的是A－当时选错原因，就是太终于原文了，原文的谓语是are hoping，但其他选项都已经改变了谓语，所以就选了。其实做的时候也知道in their attempt 不如 are attempting好。
但是碰到这类题就是不知道到底该倾向于哪一点，是原文主句成分不要变哪，还是某个词用的更合适哪？
至于这类迷惑，也就说孰轻孰重这个度该怎么把握，还请NN们指教！ 谢谢！
插入语是可以去掉不看的...所以去掉插入余如果意思变得模糊了就错...
逻辑意思为主吧,多读几次这个句子就能够发现插入语成分不应该做插入语...
愚见...
A明显的错误在attempt at doing 吧， attempt to do 多好啊
奥，这样,有道理，忠于原文的意思，不一定就是说谓语一定要是原文的谓语。
非常感谢二位！

大家参考2楼解释。
做这题的感觉似乎像是在做那种在限制性定语从句和非限制性定语从句中做选择的题目。
“are attempting to clean and preserve the American flag that flew over Fort McHenry in Baltimore in 1814”不能做插入语，因为插入语去掉不影响句子的意思表达，但这句话去掉了，意思就不对了。
