简单说说。
首先,最大的问题:第二段,第三段和第四段的第一句和后面引用的内容不直接相关。看step by step或者simon的网站很好解决。
然后,用逗号连接多个完整句子,中间不用连词的问题也不少。
最后一些基本的问题,比如but there are also private schools and clubs provide this trainning (拼写) for young children,和 they do not identify it is mother tongue or foreign language语法不过关;it helps to pronouce (拼写和用法错误) in any language。once they remember it (it is what?)
it's obvious useful,语法问题;so many good aspects listed above,语法问题;knowledges不可数,math好像不用大写,不太确定这个;有些地方前面忘记了冠词,比如 foreign language和right way;结尾不应该用English,应该是 foreign language。
