(完整版)英语语法—现在进行时(基本)
现在进行时元音:a e i o u(其它为辅音)现在进行时表示动作发生的时间是“现在”,动作目前的状态是“正在进行中”。
所谓“正在进行中”,是指在谈到这件事的时候,这个动作还在进行中。
至于它是什么时候开始的,什么时候会停下来,不是我们关心的。
所以“正在进行时”的事件,可能发生几年了,也可能只有几分钟。
仍在进行中这是“正在进行时”的关键所在。
它是一件持续进行的事情。
一.定义:现在进行时的定义:现在进行时表示现在或当前一段时间正在进行的动作.可以表示有计划的未来,也就是用现在进行时表示将来。
二.构成:现在进行时的构成是:主语+be+v。
ing〔现在分词〕形式。
be的变化在现在进行时中,be 要根据人称代词和名词的单复数不同,而分别使用am/is/are,即:I am/he/she/it 包括单数名词和不可数名词用is,you/we/they 包括复数名词用are.第一人称单数:I+am+doing+Sth.第一人称复数We+are+doing +Sth。
第二人称单(复)数 You+are+doing+Sth。
第三人称单数 He(She,it)+is+doing+Sth。
第三人称复数 They+are+doing +Sth。
三.现在进行时的变化肯定句式:主语+be( am, is, are)+现在分词+其它.否定句式:主语+be(am, is, are) +not +现在分词+其它.一般疑问句:Be(am, is, are) +主语+现在分词+其它?特殊疑问句:疑问词+be(am, is, are)+主语+现在分词+其它?对现在进行时的特殊疑问句的回答,它不可以用Yes或No直接作答,要根据实际情况回答。
现在进行时用法口诀主语在句首,am, is, are跟在后,现在分词跟着走,其他成分不可丢。
表示动作正进行,句中now时间定。
一般问句,把be提到句前去。
否定句式也简单,be后只把not添。
四.现在分词加ing的规则现在分词是在动词后加上ing 构成。
