7.Thinking
Some scientists claim that we humans are the only living things that are conscious-we alone are aware that we are thinking.
No one knows how consciousness works-it is one of science's last great mysteries.
All your thoughts take place in the cerebrum(大腦皮質),which is at the top of your brain,and different kinds of thought are linked to different areas,called association areas.
Each half of the cerebrum has four rounded ends called lobes(腦葉)-two at the front(frontal and temporal lobes) and two at the back(occipital and parietal lobes).The frontal lobe is linked to your personality an it is where you have your bright ideas.The temporal lobe is where you hear and understand what people say to you.The occipital lobe is where you record touch,heat and cold,and pain.The left half of the brain controls the right side of the body.The right half controls the left side.One half of the brain is always dominant in charge).Usually,the left side brain is dominant,which is why 90% of people are right-handed.

分析 本篇文章是科技說明文,講述了一些科學家認為人類是唯一能夠意識到我們在思考的生物,并通過對大腦功能的分析來驗證這一結論.
解答 33.B 細節(jié)理解題.根據(jù)短文中的"The temporal lobe is where you hear and understand what people say to you."可判斷出當你打電話時temporal lobe最活躍,因為它是聽見和理解人們對你說什么的部位.
34.A 正誤判斷題.根據(jù)短文中的"The frontal lobe is linked to your personality and it is where you have your bright ideas."可知一個人的個性與大腦前葉有關系,判斷出選項A是正確的.
35:C 細節(jié)理解題.根據(jù)短文中的"Usually,the left brain is dominant,which is why 90% of people are right-handed."可判斷出一個人是左撇子的原因是他的右腦處于支配地位.
