  语法是学习英语的关键,那么五年级上册学习的语法有哪些呢?一起来看看吧,下面就是小编为大家整理的英语语法,希望对大家有所帮助!

  Be动词用法

  be动词(am、is、are)+not、

  情态动词can+ not、

  助动词(do、does) + not

  如何将一个肯定的陈述句改为否定句:

  1、看句中有无be动词,如有,直接在be动词后+ not。

  2、看句中有无情态动词,如有,直接在情态动词后+ not。

  3、如上述二者都没有,就应用助动词+ not。分四个步骤:

  (1)肯定陈述句中本来是没有助动词的,要加上去,位置在主语(某人或某物)后,动词前。

  (2)确定助动词用do、does,根据句中动词,动词是原形的助动词就用do,动词是第三人称单数的助动词就用does,

  (3)在助动词后加not。

  (4)原句中动词假如发生变化就要恢复成原形。

  强调一点,有some的要考虑是否要用any。
