【五年级下册英语现在进行时讲解及简单练习译林版(5页)】在小学英语学习中，现在进行时是一个非常重要的语法知识点。它用于描述正在发生或正在进行的动作。对于五年级的学生来说，掌握现在进行时的结构和用法，有助于他们更好地表达当前正在做的事情。
一、现在进行时的基本结构
现在进行时由 “be动词 + 动词ing形式” 构成。根据主语的不同，be动词也会发生变化：
- I am playing football.
- He/She/It is reading a book.
- We/You/They are swimming.
其中，“am”用于第一人称单数（I）；“is”用于第三人称单数（he, she, it）；“are”用于其他人称（we, you, they）。
二、动词的ing形式
大多数动词在加“ing”时，只需在词尾加上“ing”。例如：
- play → playing
- read → reading
- run → running
但有一些动词需要特殊处理：
- 以“e”结尾的动词，要去掉“e”再加“ing”：
- write → writing
- dance → dancing
- 以“ie”结尾的动词，要变“ie”为“y”，再加“ing”：
- lie → lying
- tie → tying
- 以重读闭音节结尾的动词，且末尾只有一个辅音字母时，要双写最后一个字母，再加“ing”：
- stop → stopping
- run → running
- sit → sitting
