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.

思维
有些科学家称人类是仅有的有意识的生命--我们自己就能意识到思考的存在。
没有人知道意识是如何工作的---这已成为科学界最后的大迷团之一。
人们所有的思想都产生在位于大脑顶部的大脑皮质，不同的思维与不同的区域想连接，叫做关联区域。
每半个大脑皮质都有四个圆形的顶端，叫做脑叶--两片在前端（前叶和颞叶），两片在后端（枕叶及顶叶）。
前叶联系着你的性格，同时你所有的伟大创意也产生于此。
颞叶可帮你听到并理解人们对你所说的事情。
枕叶可帮你辨认出你所看到的东西。
顶叶帮你记住触觉，冷热及疼痛的感觉。
大脑的左半球控制着身体右侧的行动，右半球则控制着左侧。
总是有半个大脑处于主导地位，通常是左脑，这就是为什么90%的人是惯用右手的。
