Thinking
·Some scientists claim that we humans are the only living things that are conscious(有意识的)—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(大脑皮质),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(脑叶)—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 and 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 work out what your eyes see.
·The parietal 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 brain is dominant,which is why 90% of people are right-handed.
【小题1】Which part of your cerebrum is most active when you are making a telephone call?A．The frontal lobe.B．The temporal lobe.C．The occipital lobe.D．The parietal lobe.【小题2】Which of the following statements is true?A．One’s personality has something to do with the frontal lobe.B．Bright ideas come from the parietal lobe.C．The occipital and temperal lobes are at the back of the cerebrum.D．The occipital lobe is in charge of sound.【小题3】From the passage,we know the reason why around 10% of people are left-handed is that .A．their frontal lobe is usually dominantB．their temporal lobe is usually dominantC．their right brain is usually dominantD．their left brain is usually dominant【小题 1】B

(答案→)【小题 1】B 解析：【小题 1】这是一道细节题。根据短文中的“The temporal lobe is where you hear and understand what people say to you.”可判断出当你打电话时temporal lobe最活跃,因为它是听见和理解人们对你说什么的部位。【小题 2】这是一道正误判断题。根据短文中的“The frontal lobe is linked to your personality and it is where you have your bright ideas.”可判断出选项A是正确的。【小题 3】这是一道细节题。根据短文中的“Usually,the left brain is dominant,which is why 90% of people are right-handed.”可判断出一个人是左撇子的原因是他的右脑处于支配地位。
