【優(yōu)化指導(dǎo)】（課標(biāo)全國(guó)）高考英語總復(fù)習(xí) 課時(shí)作業(yè)48 北師大版 一、閱讀理解AIts 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 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 probably be able to do in the future.”Invisibility is an optical illusion(錯(cuò)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 then 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 do 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 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 very 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.1From the text we can see _.Ayou can be invisible by taking some medicineByou can be invisible by wearing certain clothesCDr Ulf Leonhardt knows how to be invisibleDthe Invisible Woman is a character in Fantastic Four2How does invisibility happen according to Dr Ulf Leonhardt?AThe objects disappear secretly by itself.BBy making the light come from the scenery

equipmentBincrease the radiation from mobile phones on electronic equipmentCstop the radiation from mobile phones on electronic equipmentDget rid of the radiation from mobile phones on electronic equipment4According to the passage，invisibility _.Ais impossibleBis possible in the near futureCis a fantastic dreamDonly exists in novelsBA lonely and sad pug(哈巴狗)which was photographed as he waited for his owner by the side of the road has been considered as the worlds saddest dog.Pictures of the pet taken by a passer­by have become an Internet focus after being posted on the photo­sharing website Flickr.The dog which is nicknamed Mr Newman looks terribly upset as he sits on the pavement tied to a lamppost with a rope.The photograph was taken outside a cafe in the Californian city of San Francisco，which may go some way of explaining why he is dressed in a stylish grey and purple sweater.“He was hanging around looking for somebody to love him.I tried to cheer him uphe seemed happy to see me，”said the photographer Chris Michael.One of the four photos of the pug on Flickr is titled“Tough day for Mr Newman”and with some other words as follows：“Despite_his_cool_clothes，the_girls_just_arent_interested_in_him_any_more.”Dozens of people on the site said they had been touched by the dogs pitiful expressions.“I come back to see this photo every now and then because its too cute，so does my daughter.In fact，my family all are touched，”wrote one of the pedestrians who had seen the photo.Another viewer said that she had been so moved as to buy a pug of her own after seeing the photos.Mr Newman may have won the hearts of the Internet users but he is unlikely to be more famous than a cat competitor Keyboard Cat，the musical pet who has become a star on YouTube.5The little pug waited by the road probably because _.Ait was abandoned by its ownerBit was left behind by his ownerCit was trapped by a passer­byDit couldnt find the way home6We can infer from the passage that the photographer Chris Michael _.Aknew much about the owner of the dogBhelped to find the owner of the pugCtook great interest in its colourful sweaterDtried to
