(1)C.推断题.根据"Thehumanbrainisverysmallandlightonlytwopercentofourtotalbodyweight,"可知人类的大脑占身体总重的百分之二,五十千克的百分之二为一千克.故选C.(2)B.细节理解题.根据" Whenyouwanttoremembersomething,tellafriendaboutit…Don'tover-trainyourbrain…Ourmemoryworkswellwhenweareasleep.…Ifyouhav...
根据第一段“The human brain is very small and light only two percent of our total body weight,”,可知“人脑很小,只只占我们体重的百分之二”,如果体重50公斤大脑的重量是50公斤*2%=1公斤;故选C。【小题2】推理判断题。根据文中“第二段When you want to remember something, tell a friend about ...

a人的大脑分为左右两半球,体积占中枢神经系统总体积的一半以上,重量约为脑的总重量的60%左右。 About human's cerebrum divides into two hemispheres, the volume accounts for the central nervous system bulk volume one above the half, weight approximately for about brain gross weight 60%.[translate]...
Compared to the size of our bodies, humans have much larger brains than many other mammals—but not the largest. The brain makes up 2% of a human's body mass, while the shrew's brain is about 10% of its body mass. In terms of sheer size, sperm whales and elephants take the top s...
【题文】 The human brain is very small and light (only 2% of our total body weight), but it needs about 20% of the oxygen (氧) that our body takes in. We can’t think well if our brain isn’t getting enough oxygen. So, always make sure there is enough oxygen in the air when...

Studies on human postmortem material report lower brain weights in older than in younger cohorts, whereas there is no apparent change with age in the rhesus monkey. In view of these contrasting results, we examined the pattern of brain weight across the life span in the chimpanzee, one of ...
Obviously the evolution of the size of the human brain must be studied in terms of the size of the body. Although the endocranial volume is known for many individual fossil hominids, body weight is poorly known. The present study is an attempt to estimate body weight of the South African...
