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13题答案是_______.A.However B.Moreover C.Therefore D.Otherwise
选项 A.However
B.Moreover
C.Therefore
D.Otherwise
答案 A
解析 however 然而? ?moreover 此外、而且? therefore 因此? otherwise 除此之外、否则
翻译：植物中的细胞交流是通过电信号，____植物中的信号传递只是表面上与复杂动物大脑的信号传递相似。动物的细胞不仅仅是“大量通过电进行交流的细胞”。
空格填写一个连词，体现两个句子之间的关系，根据植物与动物的对比，植物细胞是通过电信号交流的，但是动物细胞更复杂，which is more than "a mass of cells that communicate by electricity," 所以前后两句表转折。A正确。
