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 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(错觉)that the object or person is not there.Leonhardt uses the example of water circling around a stone.The water flows in，swirls(盘绕)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(超常介质)—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.

C．By curving space around the object to bend light.
D．In fact，the object or person is not there.
3．The devices could be used to ______.
A．reduce the radiation from mobile phones on electronic equipment
B．increase the radiation from mobile phones on electronic equipment
C．stop the radiation from mobile phones on electronic equipment
D．get rid of the radiation from mobile phones on electronic equipment
4．According to the passage，invisibility ______.
A．is impossible

B
A 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 world’s saddest dog.Pictures of the pet taken by a passer-by have become an Internet focus after being posted on the photo-sharing 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 up—he 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 aren’t interested_in_him_any_more.”
Dozens of people on the site said they had been touched by the dog’s pitiful expressions.“I come back to see this photo every now and then because it’s 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.
5．The little pug waited by the road probably because ______.
A．it was abandoned by its owner
B．it was left behind by his owner
C．it was trapped by a passer-by
D．it couldn’t find the way home
6．We can infer from the passage that the photographer Chris Michael ______.
A．knew much about the owner of the dog
B．helped to find the owner of the pug
C．took great interest in its colourful sweater
D．tried to amuse the pug in some ways
7．The writer used the underlined sentence from the website to ______.
A．add some humour to the passage
B．describe the pug’s loveliness
C．help the dog owner recognise it
D．attract girls to adopt the dog
8．What would be discussed next according to the text?
A．Description of another dog.
B．The pug’s recent situation.
C．Some details about keyboard Cat.
D．Pet owners’ responsibility.
二、任务型读写
(2012桐城十中高三月考)阅读下面短文，根据所读内容在表格中的空白处填入恰当的单词。注意：每个空格只填一个单词。
In addition to self-awareness，imagination，and conscience，it is the fourth quality—independent will—that really makes effective self-management possible.It is the ability to make decisions and choices and to act in agreement with them.It is the ability to act rather than to be acted upon，to actively carry out the program we have developed through the other three qualities.
The human will is an amazing thing.Time after time，it has overcome unbelievable difficulties.The Helen Kellers of this world give dramatic(给人深刻印象的)evidence to the value，the power of the independent will.
But as we examine this quality in the context of effective self-management，we realize it’ s usually not the dramatic，the visible，the once-in-a-lifetime，up-by-the-bootstraps(自立自强的)effort that brings lasting success.This special ability comes from learning how to use this great quality in the decisions we make every day.
The degree to which we have developed our independent will in our everyday lives is measured by our personal honesty.Honesty is，fundamentally，the value we place on ourselves.It’s our ability to make and keep promises to ourselves，to“walk our talk.”
Effective management is putting first things first.While leadership decides what“first things”are，it is management that puts them first，day-by-day，moment-by-moment.Management is discipline(training to be self-controlled)，carrying it out.
Discipline obtains from belief—belief in a set of values，belief in an overriding(最主要的)purpose，to a long-term or short-term goal that must be carried out.
In other words，if you are an effective manager of yourself，your discipline comes from within；it is a function of your independent will.You are a follower of your own deep values and their source.And you have the will，the quality to control your feelings and moods rather than depend on others or have your work half done.
Title The power of independent will
Theme Independent will makes self-management 1.______.
Reasons ·The example given to 2.______ power of independent will is amazing.
·Power of independent will helps to make one’s 3.______ every day.
·4.______ is very important to develop our independent will.
·It’s our ability to have our promises made and 5.______.
Suggestions ·Effective managers should know 6.______ should be done first.
·Effective managers with discipline should 7.______ to their promises.
8.______ ·You 9.______ your deep values.
·Your feelings and moods are able to be 10.______.
