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.
that plastic can be made electrically conductive--an advance that has led
that plastic can be made electrically conductive--this advance leading
that plastic can be made to be electrically conductive, and this advance led
of plastic's ability to be made electrically conductive, with this advance leading
of plastic being able to be made electrically conductive--an advance that has led
还没有题目讲解（毕出老师会陆续发布对官方考题的解读，请保持关注）。
2、this advance指代前面的同义词，如New 'Nano-papers" incorporate fibers that give these materials strength.
B，this advance leading做独立主格，伴随plastic can be made conductive，伴随状语如果没有加before/after等表示动作先后的词语，如After walking by the chocolates so many times, Roger finally had to eat one.，则要求两个动作发生在同一个时间框架里。塑料可以做导体和这个发现导致……不是一个时间框架里的事情，B错，同理D错
this advance前文没有提过哪个是advance，不能直接用this，要前文说了是advance才可以指代
an advance that 不是独立主格 是同位语 抽象noun 对前面的名词进行进一步解释
the construction of choice (c) (...and this advance led to...) seems to present two more or less independent events in sequence. in other words, the nobel prize was awarded, and, at some later point, the advance led to blah blah blah.
1、C，The Nobel Prize was awarded to three scientists for their discovery that plastic can be made electrically conductive，and this advance led ……
and+独立的句子，要么跟前面的独立的定语从句discovery that……并列，要么跟主句prize was awarded并列，两个并列都不对。同时，如果跟discovery that并列，作为第二个从句，前面有插入语，that不能省略。C错
this advance之前没有出现过，可以是作为同位语首次出现--- an advance xxx ; 而不是代词指代 this advance
"this advance" 前面没有说到Advance，也不能用并列句 - 无从说起。同时electrically 是修饰made

bcd 不能用this advance指代，前面并没有提， e赘余 职能选a
C选项的and链接两个并列独立的句子，但是原文是有因果关系的
概括性同位语
C and平行是否有问题？
C：you can't start with 'this advance' unless you're writing a new independent clause (as you would if you were following a coordinating conjunction such as 'and', 'but', etc.) if you're going to use a modifier like this, it should start with 'AN advance' (as does choice A).
this advance错误 因为前面并没有提到advance 不能用this指代
错选E, Ron's note:
the construction (preposition) + NOUN + VERBing is WRONG, unless the preposition refers directly to the NOUN. (that isn't usually the case, so, if you're in doubt, you should strike choices with this sort of construction.)
C 这不是2个分句，说的是一个意思，所以不用and
