63. The yield of natural gas from Norway’s Troll gasfield is expected to increase annually until the year 2005 and then tostabilize at six billion cubic feet a day, which will allow such an extractionrate at least for 50 years’ production.
(A) 2005 and then tostabilize at six billion cubic feet a day, which will allow such an extraction
(B) 2005 and then tostabilize at six billion cubic feet a day, an extraction rate that will allowat
(C) 2005 and thenstabilizing at six billion cubic feet a day, with such an extraction rate atthe least allowing
(D) 2005, then stabilizingat six billion cubic feet a day, allowing such an extraction rate for at least (E)2005, then stabilizing at six billion cubic feet a day, which will allow suchan extraction rate for at least答案是B。 个人对于C选项和D选项中存在疑问。 C中2005 and then stabilizing at six billion cubic feet aday, with such an extraction rate at the least allowing。我们看到C中后半部分是一个with引导的独立主格成分。按照独立主格的作用和功能,应当是表示伴随的动作,同时这里因为是with的独立主格,所以应当与前面的主语The yield of natural gas有密切联系,表示动作的伴随。但是extraction rate与前面的The yield of natural gas没有密切的从属关系,同时前面的动作的谓语是are expected to,独立主格中的动作allowing与are expected没有伴随关系。所以这里的独立主格的用法是错误的吧??? 可是OG的解释中只提到了the phrasing is awkward and unclear;并没有提到这里的独立主格的错误。 不知道我对于C中with引导的这个独立主格的看法是否正确呢,请大家指正! D中(D) 2005, then stabilizingat six billion cubic feet a day, allowing such an extraction rate for at least。我们看到最后是一个 ,+v-ing的结构。按照道理来说这个V-ing的结构应当appeal to的是主句中的主语The yield of natural gas,可是OG对D的解释说 it is not clearwhat noun allowing is supposed to modify. 求解答!
