1、2020年专升本英语语法大全If you put your hear into it,you will find it easy.第一讲第一讲.时时 态态英语主要靠动词本身形式的变化来表示动作的时间，副词的作用不大，语助词几乎没有。英语的句子，除少数特殊情况外，只要都离不开时态，都以一定的时态出现。换言之，只要是句子，就有时态问题。理由很简单：一个句子必须有主语和谓语动词（主要动词），而后者总是用于某一时态。学英语，时态是逃避不了的，但它并不是一个消极的因素。恰好相反，它有很强的表达力，能使句子的意思明确，能显示细微的差别，有时还能使句子生动有趣。一般英语有12种时态，即现在，过去，将来三大类
2、，每一类中又分为一般，进行，完成，完成进行4种。第一讲第一讲.时时 态态(一)现在完成时(1)构成 have/has+过去分词现在完成时的否定式/疑问式和简单回答形式:否定式I have not(havent)studied.You have not(havent)studied.He has not(hasnt)studied.We have not(havent)studiedThey have not(havent)studied.疑问式Have I studied?Have you studied?Has he studied?Have we studied?Have they stu
