一、閱讀理解
A
It’s unlikely to occur by swallowing a pill or donning(披上)a special cloak，but invisibility could be possible in the not too distant future，according to research published on Monday.
But Dr Ulf Leonhardt，a theoretical physicist at St Andrews University
2、in Scotland，believes the most plausible(似乎合理的)example is the Invisible Woman，one of the Marvel Comics superheroines in Fantastic Four.“She guides light around her using a force field in this cartoon.This is what could be done in practice，”Leonhardt said.“That comes closest to what engineers will pro
3、bably be able to do in the future.”
Invisibility is an optical illusion(錯覺)that the object or person is not there.Leonhardt uses the example of water circling around a stone.The water flows in，swirls(盤繞)around the stone and then leaves as if nothing were there.“If you replace the water with light t
4、hen you would not see that there was something present because the light is guided around the person or object.You would see the light coming from the scenery behind as if there were nothing in front.What the Invisible Woman does is curve space around herself to bend light.What these devices would d
5、o is to mimic that curved space，”he said.
Although the devices are still theoretical，Leonhardt said scientists are making advances in metamaterials(超常介質(zhì))—artificial materials with unusual properties that could be used to make invisibility devices.“There are advances being made in metamaterials that
6、 mean the first devices will probably be used for bending radar waves or the electromagnetic waves used by mobile phones，”he said.
The devices could be used as protection mechanisms so the radiation emitted from mobile phones does not penetrate electronic equipment.It is guided around it.“It is ver
7、y likely that the demonstration for radar would come first and very soon.To go into the visual will take some time but it is also not so far off，”Leonhardt said.
