问题 根据下列材料，回答问1-20题The idea that plants have some degree of consciousness first took root in the early 2000s; the term "plant neurobiology" was?1?around the notion that some aspects of plant behavior could be?2?to intelligence in animals.?3?plants lack brains, the firing of electrical signals in their stems and leaves nonetheless triggered responses that?4?consciousness, researchers previously reported.But such an idea is untrue, according to a new opinion article. Plant biology is complex and fascinating, but it?5?so greatly from that of animals that so-called?6of plants' intelligence is inconclusive, the authors wrote.Beginning in 2006, some scientists have?7?that plants possess neuron-like cells that interact with hormones and neurotransmitters,?8?"a plant nervous system,?9to that in animals," said lead study author Lincoin Tair, “They?10?claimed that plants have "brain-like command centers" at their root tips.”This?11?makes sense if you simplify the workings of a complex brain,?12?it to an array of electrical pulses; cells in plants also communicate through electrical signals.?13?, the signaling in a plant is only?14?similar to the firing in a complex animal brain, which is more than "a mass of cells that communicate by electricity," Tair said."For consciousness to evolve, a brain with a threshold?15?of complexity and capacity is required," he?16?. "Since plants don’t have nervous systems, the?17that they have consciousness are effectively zero."And what's so great about consciousness, anyway? Plants can't run away from?18, so investing energy in a body system which?19?a threat and can feel pain would be a very?20?evolutionary strategy, according to the article.第20题答案是_______.A.humble B.poor C.practical D.easy
选项 A.humble
B.poor
C.practical
D.easy
答案 B
解析 humble 谦逊? poor?低劣的? practical 可行的、有用的? easy 简单的
翻译：植物不能逃离危险，所以把建立一个能感知威胁和感受疼痛身体系统会是一个非常____的进化策略。
因为植物不能移动，所以进化出身体系统，然后感受到疼痛，和威胁对植物来说 ，是一件吃力不讨好的事，所以这个进化策略是非常糟糕的。B正确。
