例：I am having breakfast.为什么要用am,直接I having breakfast.不行?I 后面什么时候加am,什么时候不

这是现在进行时,用固定结构：be +动词ing
主语是I ,所以be动词用am.
I having breakfast 缺少be 动词,句子不完整,是错误的.
在一般现在时和现在进行时中 I 后面都要加 am ,在一般过去时和过去进行时中I 后面加was .
例如：I was watching TV at 8 o'clock last night.昨晚八点我在看电视.
I was sad yesterday.昨天我很伤心.

例：I am having breakfast.为什么要用am,直接I having breakfast.不行?I 后面 i am having breakfast 用现在完成时改写 I ----- breakfast at 6:00 填have还是am having after i having breakfast. madam^-^,I am having breakfast,I am going to climb mountains I ___(have) my breakfast at home必须要用am having吗?have可以吗? ‘But I am still having breakfast,’I said.变间接引语 I went to school without having breakfast. i am having a hard I'm having breakfast 和I having breakfast 有什么区别 i am still having breakfast句中的still是什么意思,它不是仍然的意思吗?怎么译成‘我正在吃 I'm still having breakfast.中的having可否用eating代替
