Why Doesn't Anybody Copy Apple？
Apple's products are the envy of the world．They have beenspectacularly successful and are widely imitated，if not copied．The
minute Apple crystallizes a product，everyone knows how to compete．
This idea that the basis of competition is set by Apple and then the
race is on to climb the path of improvement is unquestionable．When
Apple releases a product that defines a category or dramatically
changes the structure of an industry，it becomes obvious what needs to be built．But what I wonder is why everyone wants to copy Apple's products but nobody wants to copy being Apple？
I can think of two reasons．Firstly，Apple is not worth copying because it's not successful； secondly，Apple's success cannot be copied because it is a magical process．
There is a great deal of evidence for the first hypothesis．The idea of Apple being successful is not something reflected in its stock price．Being valued lower than the average company in the S&P（标准普尔）500indicates that to whatever degree Apple was successful in the past，it's not seen by the vast majority of observers as successful in the future．Why should one bother copying Apple if it results in being punished with a low valuation？If one works really hard at innovation and then that innovation becomes commoditized（商品化） very quickly，why should one bother？
When innovation practitioners are asked what makes Apple successful，the answers regarding the cause of this success border on the mythical．The climax of this hypothesis is the"chief-sorcerer"theory of success which places one magician，like Steve Jobs，in charge of casting all the right spells （符咒）．
What about Apple's own opinion of what makes it tick？Tim Cook refers to a great team and integration of hardware，software and services as unique Apple advantages．It's a better explanation． Integration is something that can take a long time，but it is possible with great effort．A few companies are starting to make moves in that direction，but efforts are half-hearted．There is no"move the Earth"panic to become an integrated company from Samsung，Google or Microsoft．
My own suspicion is that Apple is more aware of wliat makes it special than it lets out． However，as Tim points out，it's not a formula．It's complex，it's subtle，but it's not magic．It's a process that requires a degree of faith and courage．

67．When a new product of Apple comes out，often itB．
A．ruins an industry dramatically
B．starts a revolution of an industry
C．puts itself in an unbeatable position
D．is soon overtaken by imitated products
68．According to the passage，other companies don't"copy being Apple"becauseD．
A．Apple is not a successful company
B．they have no access to relevant resources
C．it's hard to find a magician like Steve Jobs
D．being Apple takes more than time and efforts
69．We can infer from Para．5thatC．
A．other companies are dedicated to integration
B．Apple itself is fully aware of its unique advantages
C．Apple will hold the leading position in this industry
D．other companies don't have a great team as Apple does
70．What does the author think of Tim Cook's statement？D
A．Convincing． B．Disappointing．
C．Unquestionable． D．Acceptable．

2．A nickname is a shortened form of a person's name．A nickname can also be a descriptive name for a person，place or thing．Many American cities have nicknames．
Los Angeles has several nicknames．One is simply the city's initials，L．A．It is also called the City of Angels because Los Angeles means"the angels"in Spanish．
Los Angeles often has warm，sunny weather．So another nickname is City of Flowers and Sunshine．New York is called The Big Apple．So Los Angeles is sometimes called The Big Orange because of the fruit that grows in that city's warm climate．
The American motion picture （电影） and television industries are based in Los Angeles．So it is not surprising that it is called The Entertainment Capital of the World．Many films are made in the area of Los Angeles called Hollywood．Millions of people visit the area．No trip to Los Angeles is complete without seeing the word"Hollywood"spelled out in huge letters on a hillside．
Many movie stars live in Los Angeles．The city is sometimes called Tinseltown．This nickname comes from the shiny，bright and often unreal nature of Hollywood and the movie industry．
Another nickname for Los Angeles is La-La Land，using the first letters of Los and Angeles．This means a place that is fun and not serious，and maybe even   out of touch with reality．
The city of Los Angeles is part of Los Angeles County．There are many smaller cities in the county．Beverly Hills，with its rich people，is one of them．So is Pasadena，with its Rose Parade each New Year's Day．
A good place for watching unusual-looking people is Venice，an area on the west side of Los Angeles．A system of waterways designed after the Italian city of Venice has been built there．

7．Yes，I admit it．I'm a true，incurable book abuser（施虐人）．I like to fold dog ears．I like to break my books open so that their backs crack．
I had a friend，who loved rubbing all the pages．I have another friend who is the exact opposite．She needs to keep her books completely new．I understand her．But once I get to know the book，I can't help but show it some tough love．Because，believe me，although it sounds like I'm an abuser without a heart，that's what it's all about．Not hidden aggressions，or a lack of respect； not at all．Let me explain．
I have one book by my favorite author Diana Gabaldon that looks like rubbish．It's completely wrinkled up from rain，and on its way to falling apart．I brought it like that to have her sign it．I hope she's realized what an honor it is to her as a writer．It means，basically，that I've read the book to bits．I wouldn't bother to mistreat books that don't mean anything to me．Only the best books get read well，carried everywhere，worth intense reading where I'm so caught up with words that I will spill coffee over it．
For my further defense，I would like to call in a witness．I have a cook book．Like almost all my other cook books，it's worn，and there are dirty marks of food in it．The book is called Tex-Mex-Food，Music and the Joy of Life from Texas．Just as the title suggests，this is more than a cook book．
These are the words on the very first page：
Tex-Max hasn't been trendy for over 30years．Considering it's anything but cheap in calories，it probably never will be，either．Tacos（墨西哥卷） are instead all about such an untrendy things as a love for life．It's something you enjoy while spending time with your loved ones．…
We hope，therefore，that this cook book will soon be as dirty as a really old and used cook book should be．
Oh，how true!How wonderful!And it's the same thing for books：whether you're a book preserver or a book abuser，the approach is based on love and a joy for life．Because I believe all who are passionate about books，are passionate people．
