Нужно выписать фразы прошедшего времени и временных выражений
It was such an important day, but I don't remember much. It's like an Impressionist painting: shapes, colors, smells and sounds too. But I was only five years old, and it was so long ago!

I went to school with my mom and cried all the way. I didn't want to leave. I had a blue backpack and a big new box of colored pencils. The playground was full of noisy, excited children. Some of the children looked huge-I had no idea I was so small! Then the bell rang and everyone stopped and went inside. How did everyone know what to do?

The walls were yellow, and there was a terrible smell of soap everywhere. My teacher's name was Mrs. Bell. ("What a strange name! I thought.) She wasn't very strict. She was actually very nice, but I didn't understand a lot of what she was saying that day. Semesters, schedules, magazines, locker rooms... What did she mean by that? And why was her voice so loud all the time? It was very strange.

I don't remember what we learned that day. I think we sang songs and clapped a lot. Mrs. Bell read the story to us, and we sat cross-legged on the floor. I was ashamed because I didn't know how to do it! There was also an aquarium with ugly fish - another terrible smell.

"So, Kate, were you a good girl today?" Dad asked me later.

“I don't know!" I said.

"Was it fun?"

"No! And Mrs. Bell said we have to come back tomorrow!” I wasn't very happy.

“Do you have new friends?"

"Yes, you have. I think...”

“Did you learn anything useful? Numbers? Colors?

"Dad! Why are you asking me all these questions? Didn't you go to school?”
