     Habits are a funny thing. We reach for them mindlessly, setting our brains on autopilot and

relaxing into the unconscious comfort of familiar routine. "Not choice, but habit rules the

unreflecting creatures." William Wordsworth said in the 19th century. In the everchanging 21st

century, even the word "habit" carries a negative meaning.

    So it seems contradictory to talk about habits in the same context as innovation (创新). But

brain researchers have discovered that when we consciously develop new habits, we create

parallel paths, and even entirely new brain cells, that can jump our trains of thought onto new,

innovative tracks.

     Rather than dismissing ourselves as unchangeable creatures of habit, we can instead direct

our own change by consciously developing new habits. In fact, the more new things we try, the

more creative we become.

    But don't bother trying to kill off old habits; once those ruts of procedure are worn into the

brain, they're there to stay. Instead, the new habits we deliberately press into ourselves create

parallel pathways that can bypass those old roads.

     "The first thing needed for innovation is attraction to wonder," says Dawna Markova, author

of The Open Mind. "But we are taught instead to 'decide', just as our president calls himself 'the

Decider'. " She adds, "however  to decide is to kill off all possibilities but one. A good innovational

thinker is always exploring the many other possibilities."

     "All of us work through problems in ways of which we're unaware," she says. Researchers in

the late 1960s discovered that humans are born with the ability to approach challenges in four

primary ways : analytically, procedurally, collaboratively (合作地) and innovatively. At the end

of adolescence, however, the brain shuts down half of that ability, preserving only those ways of

thought that have seemed most valuable during the first decade or so of life.

     The current emphasis on standardized testing highlights analysis and procedure, meaning that

few of us use our innovative and collaborative ways of thought. "This breaks the major rule in the

American belief system that anyone can do anything," explains M. J. Ryan, author of the 2006

book This Year I Will... and Ms Markova's business partner. "That's a lie that we have preserved,

and it fosters commonness. Knowing what you're good at and doing even more of it create

excellence." This is where developing new habits comes in.

1. Brain researchers have discovered that ________.  

A. the forming of new habits can be guided

B. the development of habits can be predicted

D. the track of new habits can be created unconsciously

2. The underlined word "ruts" in Paragraph 4 is closest in meaning to ________  

A. zones      

B. connections

C. situations    

D. tracks

3. Which of the following statements most probably agrees with Dawna Markova's view?

A. Decision makes no sense in choices.

B. Curiosity makes creative minds active.

C. Creative ideas are born of a relaxing mind.

D. Formation of innovation comes from fantastic ideas.

4. The purpose of the author writing this article is to persuade us ________.  

A. to give up our traditional habits deliberately

B. to create and develop new habits consciously

C. to resist the application of standardized testing

D. to believe that old habits conflict with new habits
