一株海棠花四年級作文

　　Two years ago Nova High School began to use interactive computer instruction in three academic subjects. The school dropout rate declined immediately and last years graduates have reported some impressive achievements in college. In future budgets the school board should use a greater portion of the available funds to buy more computers, and the schools in the district should adopt interactive computer instruction throughout the curriculum.

　　Sample Essay 1:

　　The argument that the school board should buy more computers and adopt interactive computer instruction is not entirely logically convincing, since it ignores certain crucial assumptions.

　　First, the argument assumes that the decline of school dropout and the achievements of last years graduates results from the adoption of interactive computer instruction. However, there are several reasons why this might not be true. For example, achievements could have been made in other subjects than the ones with interactive computer instruction. Or last years graduates might not have been given the interactive computer instruction. Or the decline of the rate of dropout could be attributed to stricter discipline applied last year.

　　Second, even supposing the Nova High Schools decline of the dropout and last years graduates achievements benefit directly from the usage of interactive computer instruction, the success of the instruction in one school may not ensure thesuccess in other schools. If it does not suit other schools, the instruction will not work.
