正在进行时的结构

现在正在进行时的句型结构
现在进行时是英语中常用的时态之一，它表示正在进行的动作或状态。

在句子中，现在进行时的结构通常为“主语 + am/is/are + 现在分词”，如：“他正在写作业”可以翻译为“he is doing his homework”。

现在进行时一般用于描述当前发生的事情，通常带有实时感和现场感，比如：“他正在玩游戏”、“她正在做饭”、“我们正在看电影”。

另外，现在进行时还可以用于表示未来的计划或安排，比如：“明天我会在家里做作业”可以表达为“Tomorrow I am going to be doing my homework at home”。

对于现在进行时的使用，需要注意以下几点：
1.常见的现在进行时句型为“be + 现在分词”，其中be的形式包括am/is/are，要根据主语的人称和单复数来决定使用哪种形式。

2.现在进行时的时间越接近现在，那么动作就越明显、突出，而如果离现在比较远，动作就会显得比较虚无缥缈。

3.现在进行时通常表示动作的持续性，即动作正在进行中，没有结束；而过去完成时则表示动作刚刚结束，已经完成了。

4.现在进行时还可以表示一个计划或安排，常用于口语或非正式场合。

总而言之，现在进行时是英语中非常常用的一个时态，掌握它的
用法对于日常交流和学习都非常有益。

需要注意的是，在实际运用中，要根据具体情况和语境来选择适当的时态，避免出现语法错误。

如：Look！The children are playing games over there．Listen！Who's singing in the classroom（2）当句子中有now（现在）时，常表示说话时动作正在进行，这时也常用现在进行时。

如：We are reading English now．（3）描述图片中的人物的动作时常用现在进行时，以示生动。

如：Look at the picture．The girl is swimming．（4）表示当前一段时间内的活动或现阶段正在进行的动作时常用现在进行时。

这时常与时间状语these days，this week等连用。

如：We are playing football these days．这些天我们在踢足球。

（5）有时句子中可能没有时间状语，但如果表示的是说话时或者现阶段正在进行的动作，就应该用现在进行时。

如：—What's Jim doing吉姆在干什么—He is cleaning the room．他正在打扫房间。

动词的现在进行时态1．现在进行时表示现在正在进行或发生的动作，也可表示当前一段时间内的活动或现阶段正在进行的动作。

现在进行时的肯定句基本结构为be（am，is，are）+动词ing.2．动词加ing的变化规则1）一般情况下，直接加ing，如：look - looking, climb - climbing, jump - jumping,play - playing, go - going , draw - drawing2）以不发音的e结尾，去e加ing.(see的e是发音的，所以不能去掉，要直接加ing。

see - seeing )如：make - making, have - having, ride - riding,write - writing, drive - driving3）如果末尾是一个元音字母和一个辅音字母，双写末尾的辅音字母，再加ing.(但是open却不属于这规则，而是直接加ing，open-opening)如：run - running, swim - swimming, sit - sitting,cut-cutting, hop - hopping, get - getting.3．现在进行时的肯定句基本结构为be（am，is，are）+动词ing.be会随着与不同的人称搭配而产生不同的变化。

如：I am playing football. You are watching TV.We are having a class. He is climbing trees.She is playing with her cat. It is running in the park.They are going home.把它们的变化编成一首顺口溜就好记多了！Look！我用am，你用are，Is 用在他，她，它，我们，你们，他们全用are。
