[简答题]Title: Left or Right Handedness Question types： Matching; T/F/NG 大致内容 左撇子的问题。说好几个理论研究用的左手还是右手。第一个是配对题。A段说，某个人提出基因是决定的关键，但是对双胞胎twins的研究发现，twins即使基因相似，但是有的是左撇子有的不是；B段说，有个人发现，在妈妈肚子里的时候，宝宝就定下了是用左手还是右手，他们在肚子里的运动会影响他们大脑的发育。C段说，左右手是和左右脑的功能区分有关，和语言有关，左脑受损的人语言会有障碍，一开始大家都觉得没道理，不过后来越来越多的事实证明了。D段说有人提出之所以这么发展是因为早期的语言与动作相连，而左脑管gesture，又管语言，和右手就一起发育起来了。EF不选，G说左撇子擅长什么，右撇子擅长什么。TFNG的题目有：那个左脑的理论在当时被大家同意，F；女人比男人更多左撇子，NG；某某人的研究中的人左脑受过伤，NG。
