问题 Coronary angiography, a sophisticated method for diagnosing coronary disease involving the introduction of a dye into the arteries of the heart, is now administered selectively, because it uses x-rays to observe cardiac function.

选项 A、for diagnosing coronary disease involving the introduction of a dye into the arteries of the heart, is now administered selectively, because it uses
B、for diagnosing coronary disease involving the introduction of a dye into the arteries of the heart, is now administered selectively, because of using
C、for diagnosing coronary disease, involves the introduction of a dye into the arteries of the heart and is now administered selectively, because it uses
D、to diagnose coronary disease that involves the introduction of a dye into the arteries of the heart, is now administered selectively, because it uses
E、to diagnose coronary disease involving the introduction of a dye into the arteries of the heart, which is now administered selectively, uses

答案 C

解析 通读A选项,并未发现很明显的错误,但唯一值得注意的就是句中作为限定词的involving现在分词短语,在A选项中involving修饰disease,但翻译过来总觉得不通;再回到五个选项中,发觉A、B、E中involving的位置都无变化,D中用that从句取代involving,但其语法功能与A、B、E中的involving是一样的,均是修饰disease的。这样几乎可以不用理解C的内容而选C了。正如考生所感觉到的,involving的内容本是介绍主语coronary angiography,而被误放在disease之后修饰disease。该句意思是:冠状血管照相术是一种诊断冠状血管疾病的复杂方法,这种方法需要把一种染料引入到血管中。但现在该方法已被选择性地使用,因为它使用X射线来观察心脏的功能。
