Between the preparation and the work,the apprenticeship (學徒期) and the actual dealing with a task or an art,there comes,in the experience of many young men,a period of uncertainty and wandering which is often misunderstood and counted as time wasted. 1       It is natural for courageous youth to know what is in life,what it means,and what it holds for its children. Behind every real worker in the world is a real man,and a man has a right to know the conditions under which he must live,and the choices of knowledge,power,and activity which are offered him. 2       It is the experience of traveling from knowledge to knowledge and from occupation to occupation.

The forces which go to the making of a powerful man can rarely be adjusted and blended without some disturbance of relations and conditions. This disturbance is sometimes injurious,because it affects the moral foundations upon which character rests. 3       The birth of the imagination and of the passions,the perception of the richness of life,and the consciousness of the possession of the power to master and use that wealth,create a critical moment in the history of youth. 4       Agitation and ferment of soul are inevitable in that wonderful moment. There are times when agitation is as normal as selfcontrol at less critical times. 5       And that in its ferment and uncertainty youth is often guided to and finally prepared for its task.

   A. It is considered richer in possibilities of all kinds than that comes at any later period.

   B. However,the wasted time will never be found back.

   C. In the education of many men and women,therefore,there comes the year of wandering.

   D. The year of wandering is not a manifestation of aimlessness,but of aspiration.

   E. And the significance of the experience in its relation to development ought to be sympathetically studied.

   F. That is why agitation and ferment of soul are ignored and even criticized.

   G. But in fact,this is a period rich in full and free development.

Time flies like an arrow before we realize it. It is known that nothing are more precious than time. The good old proverb "time is money" reminds us that time is valuable. When time goes by,it will never return back. However,it is a pity that some people don't make full use of their time.

Email has brought the art of letter writing back to life,but some experts think the resulting spread of bad English does more harm than good.

Email is a form of communication that is changing,for the worse,the way we write and use language,say some communication researchers. 1       These are a few of the recently recognized features of email,say experts,which should cause individual and organizations to rethink the way they use email.

Naomi Baron,a professor of linguistics at American University says , " 2       " She also says the poor spelling,grammar,punctuation and sentence structure of emails reflect a growing unconcern to the way we write.

Baron argues that we shouldn't forgive and forget the poor writing often shown in emails. The professor says , "   3       ”

Others say that despite its poor prose (文字) ，email has finished what several generations of English teachers couldn't: It has made writing fashionable again.

"4       " says Lancashire,a University of Toronto professor of English. "It fills the gap between spoken language and the formal methods of writing that existed before email. It is the purest form of written speech."

Lancashire says email has the mysterious ability to get people who are usually scared by writing to get their thoughts flowing easily onto a blank screen. He says this is because of email's close similarity to speech. "It's like a circle of four or five people around a campfire, " he says.

Still,he accepts that this newfound freedom to express themselves often gets people into trouble. "Almost every day I get emails that are apologies of previous emails,”he reports. In the US,the number of emails sent in a day exceeds the number of letters mailed in a year. 5      

   A. Email has increased the spread of careless writing habits.

   B. But more people are recognizing the content of a typical email message is not often exact.

   C. Email is often used to send messages,pictures to their beloved ones.

   D. It is also changing the way we interact and build relationship.

   E. The more we use email and its tasteless writing,the more it becomes the normal way of writing.

   F. Email will replace letters in the near future.

   G. Email is a critical new communication technology.
