Should students who have been admitted to a university but who can't afford tuitions are offered by government?  The author considers that those students who have been admitted to university must be excellent students and they could benefit the whole society when they graduated, so government should offer a free university education.  While it maybe true that they might benefit the whole society or even they could become a excerpt in some field, however, the author omit something that they might not top students and they might not be benefical to socity like the author said.  So, the author's opinion isn't exectly.
Not all students who have been adimtted to university are top students, because not all university are top university. Some alleyed universities are poor in quality of education, also their students dallyed all day long.  If the author stated universities are top universities,  part of students of these universities are still flamboyant.  That's because differnt areas have different quality of education, like big cities have a lot of resource of education, in the contrast, villages have scarce of resource of education.  About this phenomenon, some universities admited students from these villages that have poor quality of education in a lower score then those big cities. Such as, China's university.  In a word, not all students who have been admitted to university are top students.
But, that students who have been adimtted to university aren't top stuednts isn't equalence to government doesn't offer free university education. Because, they are not brillent students, truely, when they were offered free university education at first, however, they were longing to sophisticate knowledge, and they were diligent, someday they would become experts in any fields. On the contary, some of students dallyed all the time, even they were top students when they entered university at begaining. These students would be excellent students any more, even they fail to graduate finally. Government shouldn't offer free university deucation to the second stype of students.
Nevertheless, government shouldn't give up those students who might not benefit to society, this reason is as same as creating a new theory, the chance of successfully created the new theory is one of millions, so government should give them hand in finacal support.  At same time, under the premis that students who cannot afford tuition, government should creat a criteria to distinguish those potencial students with common students when government decided to support part of students large amout money which is used to cultivate diligent and excellent students. On this circumstance, government's policy might goad some of students whose attitude towards study is leisurely to work hard in order to gain the scholarship, which could increase the number of experts indirectly.
Although in some people's opinion, government should not offer them free university education for they would benefit society in the future, as far as I can see, government should support them because of two reasons. Firstly, some genius haven't discover their true love major, which measn they might be a common students even a bottom students. Secondly, offering them free university education could improve the level of knowledge of population.Whereas, in a nutshell, on the basic of offering students who have been admitted to university but who can not afford the tuition free university education, government also should invest money to cultivate whose brillent students who could be a expert in a field someday.
