语法在英语学习中起着很重要的地位，它是英语的核心。 为何说它是核心呢？因为当你做阅读部分的时候，你会发现文章都存在语法，如果没有语法，句子则不完美，段落也是没有层次感以及承接性。这也是我为啥先教语法的原因。语法你不会，之后的写作就无从下手；听力你也听不懂，口语更说不出，句子结构你都没搞懂，如何说出一句完整的话，可见语法在英语学习中起着重要的作用。 无论是初学者还是中学者，语法掌握度都需要加强，否则无法写出一篇高水平的作文。如果要写出一篇高级作文，一定离不开主语宾语从句运用以及连接词，还有倒装句，还有不定式等语法。语法的学习需要花更多的时间以及下更多的功夫，而且必须保持一颗想学的心，只有这样你才能较快地学好语法。不能因为语法太多知识点而抗拒以及退缩，这样下去很难学好语法。
