everyone has his ownunderstanding of young，it is a period of time of beauty and wonders，only after you have
experienced the sour ，sweet ，bitter and salty can you really become a person of significance.thre time of young is limitted，it may pass by without your attention，and when you discover what has happened ，it is always too late.grasping the young well means a better time is waiting for you in the near future，or the situation may be opposite .
having a view on these great men in the history of hunmanbeing，they all made full use of their youth time ，to do things that are useful to society，to the whole mankind，and as a cosquence ，they are remembered by later
generations，admired by everyone.so do something in the time of young，although you may not get achievements as these greatmen did ，though not for the whole word，just for youeself，for those around!
the young is just like blooming flowers，they are so beautiful when blooming，they make people feel happy，but with time passing by，after they withers ，moet people think they are ugly.and so it is the same with young，we are enthusiastic when we are young，then we may lose our passion when getting older and older.so we must treasure it ，don't let the limitted time pass by ，leaving nothing of significance.
a window is opened up at the crack of dawn， beside which one man is overlooking the the mess of buildings outside， breathing the fresh air cosily. but just after a little while， he steps to his seat， staring at the computer screen till the night. this man is very likely a programmer.
there is a man who concentrates on his computer， but doesn’t care about however he dresses， or even whether he washes his face. there is a man who has a good knowledge of computer language， but has a low eq and makes a bad relationship with others.
there is a man who stays at home and does his own work by himself day and night， but just has few friends.
these images shown above probably are what people think of
programmers as， in fact， programmers indeed give us a bad impression sometimes. however， people just have a partial understanding of programmers’ life， not to mention that they can know the fun of programming. there is no doubt that programs affect all aspects of our lives in an obvious or potential way， especially they are reflected in electronic products that we use nowadays.
when you are so proud of possessing an iphone， you’d better
remember that it is the program that makes you get confidence to show off the advanced mobile phones thoroughly.
when you take advantage of computers to cope with problems in life， you’d better remember that it is the program that makes you seek the convenience of computer.
when you needn’t worry about hot summer and cold winter owing to an air-conditioner， you’d better remember that it is the program that makes you share the machine’s intelligent.
when you release your pressure by playing varies of online games， you’d better remember that it is the program that makes you enjoy the great entertainment in life.
as people’s thoughts control their bodies， computer programs play a leading role in the modern times. both social progress and human evolution depend on the computer programs. in the practical application， a software consists of different programs and then
combines with hardware to develop into a high-tech electronic product. there are many kinds of electronic products found everywhere in our daily life. nearly all the time do we make use of these products to conduct our passion.
yes， it is definitely right that programming is a hard work because of its special characteristics---complicated， time-wasted，
logical. to make a program needs our continual patient and confidence， and we should accept failure again and again in most cases. but once you go into further understanding of computer programs， you will be surprised at the programs’ wander. in detail， through programming a heap of date or a computing model can be easily solved we expected， such as a number wanted， or the model’s parameters. the magical power of program appeals to all the programmers， certainly including me.
it is of great convenience for us to simplify or model our complex questions by programming. furthermore， studying and using programs can enforce us to form our ability of analyzing and logic.
