What happened to you
on a bad morning
First, I had slept when the clock went off.

Before I went to school, I had gone to the doctor.
What about your morning
Warming up
I had forgotten to have breakfast before I going to the office this morning.
今天早晨去办公室之前，我忘记吃早饭了。
时态分析：
“去办公室”是发生在过去的事情，而“忘记吃早饭”发生在“去办公室”之前，所以第二个谓语动作发生在第一个谓语之前，是“过去的过去”，要用过去完成时。
I had forgotten to have breakfast before I going to the office this morning.
今天早晨去办公室之前，我忘记吃早饭了。
