初中英语语法现在完成时!

初中英语语法现在完成时!现在完成时是初二学生需要研究的语法内容,也是中考的难点和重点。
现在完成时的基本结构包括肯定句、否定句、一般疑问句和特殊疑问句。
肯定句的结构为主语+have/has+动词的过去分词,否定句的结构为主语+have/has+not+动词的过去分词,一般疑问句的结构为Have/Has+主语+动词的过去分词,特殊疑问句的结构为特殊疑问词+一般疑问句(have/has+主语+过去分词)。
现在完成时的用法有两种。
第一种用法是用来表示过去已经完成的动作对现在造成影响或后果。
也就是说,动作或状态发生在过去,但它的影响现在还存在,强调的是现在。
例如:“I have already posted the photo.”(我已经邮寄出了照片)。
与这种用法连用的时间状语是一些模糊的过去时间状语,如already(出现在肯定句中)、yet(出现在否定句/疑问句句尾)、just、before、recently、still、lately、never等。
第二种用法是用来表示动作或状态发生在过去某一时刻,持续到现在并且有可能会继续持续下去。
例如:“He has livedhere since 1978.”(自从1978年以来,他一直住在这儿)。
这种用法常与for(+时间段)和since(+时间点或过去时的句子)连用。
谓语动词必须是延续性动词。
有些瞬间动词可以变为延续动词,例如go out----be out、finish----be over、open----be open、die----be dead、buy---have、fall ill---be ill、come back----be back、catch a cold----have a cold。
现在完成时在考试中常见的考法包括单选、句型转换和词语运用。
考查学生在具体语境中灵活运用时态的能力。
在考试中,会让学生判断是否该使用现在完成时,或者是考查“瞬间动词不能与表示一段时间的状语连用”的知识点。
