题目内容
15.It's puzzling,isn't it?No matter where you try to tickle (使人发痒) yourself,even on the soles (脚底) of your feet or under your arms,you just can't.To understand why,you need to know more about how your brain works.One of its main tasks is to try to make good guesses about what's going to happen next.While you're busy getting on with your life,walking downstairs or eating your breakfast,parts of your brain are always trying to predict the future.
Remember when you first learned how to ride a bicycle?At first,it took a lot of concentration to keep the handlebars steady and push the pedals (踏板).But after a while,cycling became easy.Now you're not aware of the movements you make to keep the bike going.From experience,your brain knows exactly what to expect,so your body rides the bike automatically.Your brain is predicting all the movements you need to make.
You only have to think consciously about cycling if something changes---like if there's a strong wind or you get a flat tyre.When something unexpected happens like this,your brain is forced to change its predictions about what will happen next.If it does its job well,you'll adjust to the strong wind,leaning your body so you don't fall.
Why is it so important for our brains to predict what will happen next?It helps us make fewer mistakes and can even save our lives.For example,when a chief fireman sees a fire,he immediately makes decisions about how best to position his men.His past experiences help him foresee what might happen and choose the best plan for fighting the fire.His brain can instantly predict how different plans would work out,and he can rule out any bad or dangerous plans without putting his men at risk in real life.
So how does all this answer your question about tickling,kids?Because your brain is always predicting your own actions,and how your body will feel,as a result,you cannot tickle yourself.Other people can tickle you because they can surprise you.You can't predict what their tickling actions will be.

A.it's nothing serious to get a flat tyre.
B.weather changes can be predicted by brain.

D.it's dangerous to cycle in the strong wind.
33.The phrase"rule out"in Paragraph 5probably means"D".

(37)CWhen the elephants hear the unpleasant sound,they leave,and no one is harmed.
An official for the Uganda Wildlife Authority says vuvuzelas work because they do not threaten the elephants.That is important because an elephant that feels threatened is more likely to attack.So far,no one has reported an elephant attacking in answer to a vuvuzela.
(38)GThey have built beehives-houses for flying insects that sting(叮咬).They have hung ropes covered in spicy (辛辣的) oil.They have dug long,deep holes.And they have used guns,called A-K47s.(39)D But over time,the elephants have stopped being afraid of the sound of the gun.They only look at the shooter and wave their ears.
Another official for the Uganda Wildlife Authority,Gessa Simblicious,says one elephant-prevention solution will not work everywhere in Uganda.And one day,elephants may get used to the vuvuzela noise,just as they do the sound of the A-K47.(40)F
A.They are a real danger to people. B.The big animals are friendly to the local people. C.The instruments make a loud sound elephants do not like. D.People shoot the gun in the air to scare the elephant away. E.The elephants are cruelly killed in large numbers in Africa. F.But right now,vuvuzelas are an effective way to deal with a serious problem. G.Villagers have tried other ways to stop elephants from coming near farms and houses. |
