听力文本Right,the tpic f tday’s lecture is“The Brain”. Well,the brain is an abslutely amazing rgan. It cnsists f grey and white matter. It weighs just ver a kil—just imagine that,like a kil f ptates. But this is a very special kil. It uses twenty percent f the bdy’s energy and it cntains ver ne hundred billin cells. One hundred billin cells! These make up nerve cells,which are cnnected by electrical impulses. The brain sends messages using electrical impulses,the same way as a cmputer wrks. But there are mre pssible cnnectins in ne brain than there are atms in the universe. Just think abut that again. There are mre pssible cnnectins in yur brain than there are atms in the universe. Amazing,isn’t it? Makes a nrmal cmputer lk simple,desn’t it?

Like explrers explring the wrld,they’ve fund that there are different areas in the brain and these areas are respnsible fr different functins. We nw knw which parts f the brain are related t different parts f ur bdy and feelings frm them. A gd example f this can be seen in peple wh have lst an arm r a leg in an accident. Thugh they dn’t have an arm r a leg,they can still have feelings frm it,like pain. Incredible,isn’t it?Yu als have different areas fr different kinds f thinking. Fr example,yu have ne area fr yur first language and anther area fr a freign language that yu learn when yu are lder. Interesting,isn’t it? even mre interesting than lcating different areas f the brain is...
