今天做OG第四段阅读第一个问题时做错了,看了答案还是不太理解。因此想向各位高手求教。 1.According to paragraph 2, what evidence indicates that aggression in animals is related to the hypothalamus? a some aggressive animal species have a highly developed hupothalamus. b Artificial stimulation of the hypothalamus results in aggression in animals c Animals behaving aggressively showed increased activity in the hypothalamus d Animals who lack a hypothalamus display few aggressive tendencies. 一上来可以派出a和d项,但是第二项错在哪里呢?即使是后面的分析,也还不是很清楚,向大家求教,谢谢! |
