平行结构那一章的。
As envisioned by researches, commercial farming of lobsters will enable fisheries to sell the shellfish year-round, [taking advantage of off-season demand, standardize] its sizes and colours, and to predict sales volume in advance.
A. taking advantage of off-season demand, standardize
B. taking advantage of off-season demand, to standardize
C. taking advantage of off-season demand, standardizing
D. take advantage of off-season demand, standardize
E. take advantage of off-season demand, to standardize
这里taking的功能就是”逗号+doing“的格式作为独主，要满足3点
1. share前面句子的主语---share的是fisheries
2. 修饰整句
3. 形容这个action---形容这个sell的功能，如何sell
所以这里应该是用selling来做划线开头的内容
独主是强调结果的，（是一种unavoidable, direct consequence)
还有一个同能就是强调同时，at the same time作者: liulu007 时间: 2012-3-2 06:59
taking难道不是伴随状语吗？

A. taking advantage of off-season demand, standardize
B. taking advantage of off-season demand, to standardize
C. taking advantage of off-season demand, standardizing
D. take advantage of off-season demand, standardize
E. take advantage of off-season demand, to standardize
E选项我觉得是这样的。功能不明确的意思是，take advantage没有平行的对象，看划线句后面的and to pridict, to pridict 是与to sell 平行的。所以take没有平行的对象。
我们只能说 to do A,to do B, and to do C 或者 to do A,do B,and do C.
最后一项一定要加and并且和第二项的形式相同，也就是说第二项决定了后面所有项是用to do 还是 do..作者: francessaa 时间: 2012-3-2 21:39
