People have different views about what subject university students should study, whether the one they like or only the one that will be useful in the future. People who believe students should only study subjects that will be useful in the future list several reasons. First, university courses like medicine, engineering and information technology can provide more job opportunities, career progression, better salaries, and therefore an improved quality of life for students who take them. Second, those subjects play the major role in new inventions, economic growth, and the society' s greater future prosperity. As far as I am concerned, university students should be free to choose their preferred subjects. In my opinion, students can study well if the learning content caters to their interest. Besides, the creative thinking patterns behind some theoretical subjects have potential value. In this sense, more students of art, history and philosophy are needed. In conclusion, although it might seem sensible for students to focus only on the most useful subjects, I personally assert that they have the right to study whatever they like.

This table ilustrates the difference of degree of satisfaction among employees at different ages in some company.In general,the overall trend of the degree of satisfaction is different with the variation of ages.Of those who feel satisfactory about their jobs,those beyond 50 years old take up the majority,accounting for 40%,followed by those who are no more than 40 years old,which take up 16.7%.Those between 41 to 50 years old have the lowest satisfactory rate,merely0.0%.Of those who feel dissatisfactory about their jobs,those between 41 to 50 years old take up the majority,accounting for 64.0%,followed by those less than 40 years old,which take up 33.3%.Those who beyond 50years old enjoy the lowest dissatisfactory rate,taking up only 10%.Besides,there are still 50.0%of less than 40 years old employees,36.0%of those between 41 to 50 years old and 50.0%of over 50 years old employees remaining uncertain about the degree of satisfaction.The contributory factors to this result can mainly divide into three parts.Firstly,those less than 40 years old are ambitious,impractical and eager to find their places in work.With those characteristics,they often get upset find their places in work.With those characteristics,they often get upset when they fail to fulfill their goals.Secondly,those between 41 to 50 years old employees,confronted with challenges posed by their young colleagues,often face a great deal of working competition and pressure.Lastly,with their impending retirement,those beyond 50 years old face relatively small working pressure and feel satisfactory about their jobs.From this table,we can make a conclusion that if the companies want to raise the degree of satisfaction of its employees,it should make more efforts to improve the working environment,ameliorate the welfare and establish the effective incentive mechanism.

Will E-books Replace Traditional Books? There is no denyingthe fact that e-books have gained increasing popularity in the past years alongwith the development of information technology. Actually, modem readers seem tospend more time on e-books than on traditional ones.
As a consequence, ithas emerged as a hotly debated topic whether e-books will take the place oftraditional books in the future. Some hold the positive view. They claim thatit is natural for books to become electronic as mankind steps into a digitalage. Compared with traditional books, e-books have some obvious advantages. Forone thing, it is convenient to read online as modem people have easy access tothe Interact. For another, reading e-books saves money.
Personally, Ibelieve that e-books cannot replace all traditional books. Firstly, you canmark a traditional book and write your comments in the margin but you can hardlydo that on e-books. Secondly, for many people, only the smell of print and thefeel of paper can provide, the true sense of reading and learning. Therefore,in my opinion, traditional books will still exist in the future.
