With the importance of education advanced in modern society(用ing形式,换个句型可能就通一些)(在这里再加一句关于背景的描述再引出后面的观点可能会更自然些), I tend to agree with the speaker that education should not be only left solely to (a group of people -- even though they are) (用local schools—though they are cultivated by怎样?) the most professional educators, and(加个that好些吧,与前个并列) both parents and communities should take part into the educational activities(加上to―或者 so as to之类的表目的会更好些,句子会更丰满), either.
In the first place, professional educators play an important role in the education for students. By the effective and professional systemic(不要) method (s)of education and a long-term experience(具体限定是什么经历为好), every student can be ensured(用给了一个机会干什么更好些吧,你这样说太绝对了) to learn the necessary and basic knowledge and skills. For instance, Teaching in the class is the first step(干什么的第一步?)(如果是后面的从句,则不妨不用好,用of helping students―――可能更好), which help students have an elementary view about them should learn. After that teacher will leave some homework to students and they could have a chance to review the knowledge(将知识写成更具体的东西会更好些,什么样的知识,又起到例证之效), and the things(同样用具体的来代替things好些) they learned(learn是学会了,这里用study好些) will be more clearly(这个用词不太好) and will not be forget easily. With the final exam in the end of the semester, it (it是什么指代?)will test if the students (had,时态问题)gain what teachers (同前)told, and the exam is also a compelling way to force students who do not want to study to remember some basic knowledge. By these series of methods, students can get some useful stuff whether they( have interesting to it)?.(后面都不要,否则节外生枝,甚至跑题) Furthermore, Teaching is a job for those professional educators that they earn the money from the government. Cultivating and teaching is their responsibilities.
