初中是开始学习系统语法知识的.重要阶段。

这阶段语法学习好了,以后语法就会感到很轻松。

首先应该明确是初中的时候我们学习的更多的是词法而不是句法,因为毕竟从简单开始吧,就算是中考题也基本上没有多少句法的题,所以初中一定要把重心放在词法上。

学习英语贵在坚持,找到适合自己的方法,多运用多温故。

英语学习过程是一种观察,模拟,认识,识记,思考,记忆等综合的心理活动过程。

建议从学单词开始就听写背单词,建立起人对英语单词声音形象的条件反射能力。

其间接形容词时,有时该形容词还可修饰另一名词,但那个名词应带有不定冠词(注意词序):She is as good a cook as her mother. 她和她妈妈一样是位好厨师。

也可说:She is a cook as good as her mother.但不说:She is as a good cook as her mother. 或They are as g ood cooks as us.二、关于第二个as的词性第二个as后接从句时,该as通常为连词,但有时那个as还充当其后从句的主语或宾语,现在该as实为关系代词。
