19．No one should be forced to wear a uniform under any circumstance．Uniforms are controlling the human spirit and totally unnecessary in a democratic（民主的） society．Uniforms tell the world that the person who wears one has no value as an individual but only lives to function as a part of the whole．The individual in a uniform loses all self-worth．
There are those who say that wearing a uniform gives a person a sense of identification with a larger，more important concept．What could be more important than the individual himself？If an organization is so weak that it must rely on cloth and buttons to inspire its members，that organization has no right to continue its existence．
Others say that the practice of making persons wear uniforms，say in school，gets rid of all envy and competition in a matter of dress，such that a poor person who cannot afford good-quality clothing is not to be looked down upon by a wealthy person who wears expensive clothing．Those persons ignore the concepts as freedom of choice，motivation，and individuality．If all persons were to wear the same clothing，why would anyone struggle to be better？It is only a short step from forcing everyone to drive the same car，have the same type of food．When this happens，all motivation to improve one's life is removed．Why would parents bother to work hard so that their children could have a better life than they had when they know that their children are going to be forced to have exactly the same life as they had？
Uniforms also hurt the economy（經(jīng)濟(jì)）．Right now，billions of dollars are spent on the fashion industry yearly．Thousands of people are employed in designing，creating，and marketing different types of clothing．If everyone were forced to wear uniforms，artistic personnel would be unnecessary．Salesmen would be extra as well．Why bother to sell the only items that are available？The wearing of uniforms would destroy the fashion industry which in turn would have a wave effect on such industries as advertising and sales promotion．Without advertising，newspapers，magazines，and television would not be able to remain in business．Our entire information and entertainment industries would collapse．
68．Why does the author discuss forcing everyone to buy the same car or eat the same food？B
A．To show that freedom of choice is absolute in modern society．
B．To suggest what would happen if uniforms became compulsory．
C．To predict the way the society will be in the next few generations．
D．To show that the government has too much control over people's lives．
69．The last word of the passage"collapse"probably meansA．
A．fail
B．rise
C．disappear
D．struggle
70．The author's primary purpose in writing this passage was toD．
A．show that uniforms are not possible in a democratic society
B．a(chǎn)dvise the government to change the rules of wearing uniforms
C．a(chǎn)dvocate stronger governmental controls on the wearing of uniforms
D．convince the reader that uniforms have more disadvantages than advantages．

20．Even when you're extremely busy，you aren't using your time with 100% efficiency．There are gaps in everyone's schedule where they aren't doing anything important．Even if your schedule has no gaps，there is probably lots of time where you aren't working as fast or as effectively as you possibly could．
Why aren't you completely efficient？It's because time isn't the limiting factor．If it were the limiting factor，people could work non-stop without breaks or any unproductive distractions（消遣）．Instead，people，even those who are highly productive，need to take breaks，occasionally procrastinate（拖延） and slow down on tasks throughout the day．
The real and most important limiting factor for productivity is your energy levels to pay attention．Energy levels limit your productivity because when you're tired，you can have ample time and still not get everything done．Your attention ability is also limited，because even if there are a million things that need to be done，you can only focus on one or two at a time．
You might not be able to insert another 4-5 hours into your schedule without making some sacrifices．But even extremely busy people can add an hour or two into their schedule without cancelling anything．The reason it's hard to"find time"isn't a lack of time．It's because you don't have enough energy left to focus on something else that needs to fit into your day．
I first suspected time wasn't the real problem during an extremely busy period in my life over a year ago．I was insanely busy，but at that time I still exercised regularly．I had daily to-do lists with over twenty items，and I still found time to exercise．However，after a few weeks off，due to illness，I stopped exercising．I was not busy by any standards，in fact，my schedule was incredibly light．Despite this free time，I found it hard to find time to exercise．It seemed to get pushed later and later into my schedule until it was gone．How can I explain this odd experience？I believe you have known it．
 
26．If someone can't work with 100% efficiency，the most important limiting factor isD．
A．a(chǎn) schedule without gaps                
B．breaks and distractions
C．the limited time                       
D．the limited energy
27．According to paragraph 4，everyone，including the extremely busy people，canC
A．work without any rest                   
B．focus on many things at a time
C．find some more time in a day           
D．do some exercise regularly
28．After a few weeks off，what was the change of the writer's life？B
A．He had a longer daily to-do lists with over twenty items．
B．He stopped doing exercise because of the lack of energy．
C．He found it hard to find time to exercise because he was busier．
D．He pushed most of the things later and later in his schedule．
29．The writer gives the example of himself in the last paragraph in order toAA．prove what the real limiting factor is                    
B．show us how busily he needs to work
C．explain how important a healthy body is             
D．tell us what an odd experience he has
30．What is the best title of the passage？A
A．Are You Really Lack of Time？
B．How Can You Work Efficiently？
C．What Makes Your Energy Limitedd？
D．When Should You Do Exercise？

The store owner smiled and whistled，taking out five dogs．One puppy was left behind，immediately the little boy singled it out and said，"What's wrong with that little dog？"The store owner explained that the little puppy was disabled．It would always be lame．

The little boy got quite upset，looked into the store owner's eyes，pointing his finger，and said，"I don't want you to give him to me．That dog is worth event bit as much as all the other dogs and 1'11pay full price．In fact，I'll give you﹩2.50now，and 50cents a month until I have him paid for．"

On hearing this，the little boy reached down and rolled up his pant leg to reveal a badly twisted，crippled left leg supported by a big metal brace．He looked up at the store owner and softly replied，"Well，I don't run so well myself and the little puppy will need someone who understands!"
