??主张本届考研的同学不要如今就对答案！避免影响接下来的考试，假定怕忘掉就用纯真题版标示好，明日共同估分的时分再对！
大众号：考研哟，为我们专门分隔两个版另外，要害词别离为：“纯真题”、“答案版”，我们按需获取，因为不影响到本届考生，因而以下的真题优先无答案，需要答案的同学请按上述方法触发要害词获取，还望了解（另答案仅供参阅，当前各方答案出入比照大特别是片面题，这也是不主张本年考的同学这么早对答案的缘由之一）。

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??(6) ?of 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, ?(9)??to that in animals.”said lead study author lincoln taiz, “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.”taiz 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??(17) ?that they?have consciousness are effectively zero.”
