初中英语语法有主谓一致,被动语态等。
被动语态根据时态的不同,可分为以下几种类型:
一般现在时:am、is、are+done;般过去时:was、were+done。
现在进行时:am、is、are+beingdone过去进行时:was、were+beingdone。
将来时:will、would+be done,be going to be done,be to be done
现在完成时:have、has+been done。
过去完成时:had+been done。
将来完成时:will+have been done。
主谓一致指的是句子的谓语动词与其主语在数上必须保持一致,句子的主语是第三人称单数,其谓语动词须用单数,主语是复数,则谓语动词用复数。
主谓一致的三个原则。
英语中的主谓一致主要遵循三个原则:意义一致原则、语法一致原则和就近原则。这三个原则堂堂发牛矛盾,但当发生冲突时,意义一致原则为优先考虑的原则。
怎么学习英语语法:
单词的学习和朗读课文是基础,没有单词的学习和课文的朗读是学不好语法的。也就是说语法的学习不可独立来看。
语法又分为词法和句法。词法是指具体一个词语的用法,所以词法是很多的。比如forget可以接to do,也可以接doing。语法的学习就是理解句子的成分,结构。通过句法的学习可以准确理解句子的含义。
简单句的学习要容易的多,如果遇上复合句,就要复杂的多,比如主语从句,宾语从句,同位语从句等。
语法的学习还要学习时态,比如一般过去时,一般将来时,一般现在时等都要借助时间来准确理解。
语法的学习最好借助练习题来完成,语法知识只有在运用中才能检验自己是否真的学会了。是否可以转化成自己的能力。
