英语高手帮我看看我这两个句子有没有语法错误
Those teachers who dedicate themselves in basic education,virtually,don't need to attend courses to update their knowledge.Since their teaching propose are mainly to increase students' all-round envelopment rather than just teach knowledge.
On the other hand,it's fairly necessary for teachers who work in higher education institution such as colleges or universities to take part those academic courses.Because higher education needs a high quality of scholarly level.
这是我写的一篇文章的两个主题句.
文章的议题是老师是否因该每五年参加一次培训课去更新他们的知识.
恳请您看仔细一些,包括逻辑关系,用词,语法等.考试在即.好的话会追加

Answer 1

第一句dedicate to而不是in
第二句改为teaching proposes,envelopement你是想说development吧?
第二段第一句改为institutions,take part 后面加 in
最后不要用a high quality of scholarly level,因为需要的是“学术水平”而不是“高质量”.而且水平只有高低只说,而没有质量之说,因此建议改为extremely high academic level.你查柯林斯词典就知道scholarly不能这么用.
