2、第一可以使你学得快些，因为已有现成的前人总结的法则，用不着你从头摸索。第二可以使你学得透些，因为通过语法对语言现象不仅可以知其然，而且可以知其所以然。第三可以使你学得准些，因为语法法则就是一条条准绳，可以用以衡量一句话是否正确。第四语法不但可以引你入门，更可以引你入胜，使你逐渐眼界开阔，语感加深，从而使你的英语水平不断提高。丨那么应该如何学习语法呢？我认为在学习语法过程中，应该注意下面几点：第一基本概念最重要。在学习每个语法项目时，一定要把它的基本概念搞清，牢记在心。第二要大量地实践，大量地练习。实践要包括听、说、读、写四个方面，练习要着重说和写。第三学习语法时，应多用比较法。如对动词时态、冠
3、词、介词、名词的单、复数等较难的语法项目进行相互比较，效果就比较好。 第四要将语法法则与习惯用法分开。碰到习惯用法，就不必钻牛角尖，进行徒劳的分析。而习惯用法在英语中则是大量地存在着的。第五将一本语法书通读一遍，当然也不无好处。但最好将它作为工具书，像词典一样地经常查阅，始能学得比较细致牢靠。第六实用英语语法只应是入门的向导，像一根拐棍一样。英语达到一定水平之后，就应将它扔掉。起码不要让许多语法条条充斥头脑，影响你说和写的流利性。最后可能还会有人说，语法应该学，就是太枯燥。我的感觉是：开头有点枯燥，过些时候，就会像嚼橄榄似的，越学越有味了。如若不信，请试试看。 】薄冰初中英语语法之助动词和情态
