work在这里是作为不可数名词,但是80% of our work是作为单数名词,所以后面是has been finished或is finished,前者finished是动词过去分词,后者finished是形容词.hard work里的 work是不可数名词,前不能加不定冠词a.such（a）用在名词前（带或不带形容词）.so用在形容词前（不带名词）.so不能修饰起前置修饰作用的形容词hard.so更不能置于以不可数名词work为中心词的名词短语之前.所以不能用so,综上所有条件,选择B选项.
选C。 第一处“80% of our work”中的“work”是不可数名词，它指代工作的完成量，是一种抽象概念，所以无法用数的来表达，因此选“has been done”。如，How much candy can you eat within a minute？这里的candy是不可数名词，指的是所有糖果的总称，或者是所有甜的东西，所以用much来修饰而不是many。第二处的“work（没有复数...

选C。 第一处“80% of our work”中的“work”是不可数名词，它指代工作的完成量，是一种抽象概念，所以无法用数的来表达，因此选“has been done”。如，How much candy can you eat within a minute？这里的candy是不可数名词，指的是所有糖果的总称，或者是所有甜的东西，所以用much来修饰而不是many。第二处的“work（没有复数）”表示“一种工作的意思”，此时同“job”。 所以可以用量词来修饰。举个例子，-I have found two works(jobs) today and it's a really a big day for me.
所以分清一个事物可数还是不可数，关键得看在语境里的意思。现在很多单词在使用中都不像咱们课本里规定的那样，课本里的只是适用于考试。

不明白上面说的。既然是HAS been done,为什么选C呢？it is such a ```这个倒是好理解。所以我觉得第一个是has been，第二处是such a所以我觉得没正确答案。
选B吧。
C
WORK是单数所以后面也要用单数
