故选B3. 根据第二段第一句“the human brain has become smaller over the past 20,000 years.”可知人类的大脑相较于过去20000年变小了,所以B选项的图正确。故选B4. 根据第六段第一句“Brian Hare …said, "Smaller brain size doesn't mean that modem humans are less smart than ancient people.”可知...
Believe it or not, the size of the human brain has become smaller over the past20,000 years. Scientists argue over whether this means we are becoming more or lessintelligent as a species.The size of the average moderm human brain has declined 10 percent over theperiod - from 1,500 to ...
(C)Brain(大脑)size has reduced over the last 20,000 years.Believe or not, the human brain has become smaller over the past 20,000 years. Scientistsargue over whether this means we are becoming more or less smart.The human brain has got smaller by 10 percent over the years, from 1 ,...
根据上文“the size of the human brain has become smaller over the past 20,000 years(在过去的2万年里,人类大脑的体积变小了)”可知,人们大脑的体积变小了,所以可推知,划线词downsize意为“缩小尺寸”。即所在句子意为“我把这种大规模的变小称为进化的一眨眼的功夫”。A. Speed加速;B. Increase增加;...
The human brain is the most complex and poorly understood biological structure known to man. Our human brain is relatively large for our body size and wrinkled in comparison to other animals’ brains. Across species, brain size and wrinkle number is related to intelligence. University of Copenhage...
B Believe it or not, the size of the human brain has become smaller over the past 20, 000 years.Scientists argue over whether this means we are becoming more or less intelligent as a species."I' d call that major downsizing in an evolutionary eye blink(眨眼)," John Hawks tol d Discov...
(八)Why are brains smaller?Believe it or not, the human brain has become smaller over the past 20, 000years.1argue over whether this means we are becoming more 2 less smart.The human brain has shrunk by 10 percent over the 3 -from 1,500 to1,359cubiccentimeters(立方厘米). The missing...
根据上文“the size of thehuman brain has become smaller over the past20,000 years(在过去的两万年里,人类的大脑变小了)”及构词法down(往下,向下)和size(尺寸)可推知,downsize意为“缩小;精简”。speed“加速”;increase“增加”;decline“减少”;change“改变”。故选C项。5.A推理判断题。根据第五段...
As brain size increases, the cortex thickens only slightly, but the degree of sulcal convolution increases dramatically, indicating that human cortices are not simply scaled versions of one another. Our results are consistent with previous hypotheses that greater local clustering of interneuronal ...
