                                                       The Loss of Innocence(纯真)

     Innocence is such a precious gift. It's explained as freedom from guilt or wrong doing. Just imagine

never having to worry about anything and having a guilt-free mind. Some people wish to save this kind

of innocence from being lost from childhood to adulthood.

     What would the world be like if innocence were never lost? One way it would benefit humanity is the

lack of hatred (仇恨) among the world. During youth, there may be an occasional argument, even a little

physical fight, but nothing like firing a handgun at a fellow human being. And children are blind towards

the racial differences of others. A kid will hang out with any other kid. It is the lack of innocence and the

ignorance we learn from adults that influence children otherwise. Another benefit is the constant desire for

fun and adventure. With very little if any time at all for fun, the adventurous mind is lost in time with the

responsibilities placed upon adults. If innocence were kept alive, these ambitions would never depart from our lives.

     However, other people actually hate the idea of innocence lasting for ever. They feel that the lack of

organization and mental power of those with innocence would cause extremely destructive consequences

to society in general. A large number of individuals would never have the urge to learn, work, and act

upon the necessary needs for humanity to survive. Without a proper education which is usually provided

by those who no longer live in a world of innocence, people would not have the desire to succeed, get a

good job in life, or provide income for their families, which

would hurt the lives of children.

    The lack of a good education and career would also harm the economy. As long as innocence is kept

alive, no one would be terribly angry at the lack of effort people put out in the workplace, resulting in a

strong decline(减少) in production and quality of needed goods.

     Maybe it is wrong in wanting to save innocence. It sure is a nice thought, though. Perhaps innocence

was meant to be lost. It was god's will to make things the way they are, and there is a good purpose for

everything. All that remains to be said about innocence is to enjoy it while it lasts.
