The following appeared in a report by the School District of Eyleria.
"Nationally, the average ratio of computers to students in kindergarten through grade 12 (K-12) is 1:5. Educators indicate that this is very good ratio. This means that across the country, all students have access to and can use computers daily in their classrooms. In Eyleria's K-12 schools, the ratio of computers to students is 1:7. This number is sufficient to ensure that all of Eyleria's students, by the time they graduate from high school, will be fully proficient in the use of computer technology. Thus, there is no reason to spend any of the schools' budget on computers or other technology in the next few years."
这是我的第二篇正式的argument，没有参照模板，字数比较少。麻烦帮忙找错误，提意见，O(∩_∩)O谢谢~~



     According to the argument, we can see that the author has made some arbitrary conclusions that cannot convince others very much, for instance, the relationship of the ratio with the sufficient daily use of the students in the classroom. The ratio cannot also guarantee whether it needs to pay more budgets on the computers or other technology.
     First of all, the author gives an example that educators indicate 1:5 is a good ratio, but it is confused that whether the educators are authoritative. Meanwhile did the educators mean that 1:5 can guarantee across the country, all the students have access to and can use computers daily in their classrooms. The author may have made a fallacy that misunderstanding the meaning of the educators.
    Even if the educators have meant that 1:5 is a good ratio that can guarantee the sufficient use of computers across the country, it cannot conclude that 1:7 in the E K-12 is sufficient to ensure that the students will be fully proficient in the use of computer technology. Quantity cannot equal to quality, though the student may have sufficient chances to touch the computers, they may have difficulties in being fully proficient in the use of the computer. To say the least, the computers the school owns may have low quality that can just be used for practicing typing. The number of the low quality computers is so large that it can affect the sufficient use in more complicated fields. In a word, 1:7 cannot be guaranteed a good ratio.
    Moreover, the sufficient uses of the computers do not mean the computers do not need to be updated or maintained. As we all know, the software of the computers update quickly, it needs at least three or four years to change the equipments. It needs to change or upgrade the software in order to catch up with the development of the society, this means much budget may be needed in the upgrade of the computers. May the education does not need very progressive software, the computers are still needed to be maintained at regular time, because there are always some minor defects.
      Meanwhile, the education in the school may need some more other technology such as multi-medias, audios, microphones, they all need to be maintained. It means much more budget should be used in them.
      The author may need to make a more detailed investigate in order to make some more convinced conclusion. For example, the quality of the computers of the school, the warranties the computer companies offered or the skill and the payment of the school，s maintainers, some other technologies used in the school.
