The Nobel Prize in chemistry was awarded to three scientists for their discovery that plastic can be made electrically conductive--an advance that has led to improvements in film, television screens, and windows.
(A) that plastic can be made electrically conductive--an advance that has led
(B) that plastic can be made electrically conductive--this advance leading
(C) that plastic can be made to be electrically conductive, and this advance led
(D) of plastic's ability to be made electrically conductive, with this advance leading
(E) of plastic being able to be made electrically conductive--an advance that has led
解释说b项错在this是特指,这个明白了。可解释又说this advance leading缺少谓语结构。。。这我就不明白了,那a项的谓语结构在哪呢??一个定从修饰,一个分词修饰名词,除了时态,有什么区别,怎么能说b项缺少谓语结构呢?
像楼上所说,A答案破折号后面的是同位语.an advance是discovery的同位语,不需要谓语.
B答案的This的确指代不清.但我并不认为this advance leading错在缺少谓语. "n., n. doing sth"可以成为独立主格修饰前句,语法上它是没有错的.
欢迎NN们拍砖.
同意楼上,b项个人认为有两个错误,一个是时态,一个是this的使用.
嗯,听大家这么一说就权且当写解释的人写错了。但对于时态的问题我恰好有疑问,当初选b就是觉得a后面的时态不对。这里为什么要用完成时呢?难道以后就不led了吗?我总觉得优势引导进步不是引导完了就完了,而应该是个持续过程。
当然如果说是引导了进步才让他们获得诺奖的,那就必须是个结果,这样反而好像说通了。大家觉得我这么理解对么?
能把那题发出来吗?
