问题 As envisioned by researchers, commercial farming of lobsters will enable fisheries to sell the shellfish year-round, taking advantage of off-season demand, standardize its sizes and colors, and to predict sales volume in advance.
选项 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, standardizing
E、take advantage of off-season demand, to standardize
答案B
解析 本句是enable sb．to do sth．的习惯用法。根据动词不定式平行结构的第一个to sell和最后一个to predict的形式，则要求与其平行的中间部分同样要补进to，而D、E中take用原形，未补出to，不符合平行的原则，排除D、E。由选项A、B、C就可断定taking是作前半句的伴随结果。A中，standardize之前未补出to；而C中用standardizing使句意不通，且两个现在分词之间缺and连接。选B，表明standardize与sell和predict并列。
