问题     The idea that plants have some degree of consciousness first took root in the early 2000s; the term “plant neurobiology” was ____【B1】____ around the notion that some aspects of plant behavior could be ____【B2】____ to intelligence in animals. ____【B3】____ plants lack brains, the firing of electrical signals in their stems and leaves nonetheless triggered responses that ____【B4】____ consciousness, researchers previously reported.
    But such an idea is untrue, according to a new opinion article. Plant biology is complex and fascinating, but it ____【B5】____ so greatly from that of animals that so-called ____【B6】____ of plants’ intelligence is inconclusive, the authors wrote.
    Beginning in 2006, some scientists have ____【B7】____ that plants possess neuron-like cells that interact with hormones and neurotransmitters, ____【B8】____ “a plant nervous system, ____【B9】____ to that in animals,” said lead study author Lincoln Taiz, “They ____【B10】____ claimed that plants have ‘brain-like command centers’ at their root tips.”
    This ____【B11】____ makes sense if you simplify the workings of a complex brain, ____【B12】____ it to an array of electrical pulses; cells in plants also communicate through electrical signals. ____【B13】____, the signaling in a plant is only ____【B14】____ similar to the firing in a complex animal brain, which is more than “a mass of cells that communicate by electricity,” Taiz said.
    “For consciousness to evolve, a brain with a threshold ____【B15】____ of complexity and capacity is required,” he ____【B16】____.” Since plants don’t have nervous systems, the ____【B17】____ that they have consciousness are effectively zero.”
    And what’s so great about consciousness, anyway? Plants can’t run away from ____【B18】____, so investing energy in a body system which ____【B19】____ a threat and can feel pain would be a very ____【B20】____ evolutionary strategy, according to the article.
【B12】________
选项 A、attaching
B、reducing
C、returning
D、exposing
答案B
解析 固定搭配题。空白处所在的状语结构，是对主句谓语simplify(使简化)的一种伴随状态，所以，空白处语义与simplify(使简化)语义相近。B项reducing与介词to搭配，表示“将……概括为(或简化为)”，代入后符合原文语义。所以，本题答案为B项。
