Past Tense in Japanese / Tabemashita / たべました

Hi, this is Yuyujin.

Do you enjoy Pyeong Chang Olympic?
I watch the games on TV everyday.

I am interested in the curling.
Satsuki Fujisawa, a member of Japanese woman curling team, is getting popular in Korean.
I have read the news she is chosen as “The 10 beautiful woman who shoots a man’s heart” by Korean media.

Today I would like to introduce past tense in Japanese.

Today’s pattern is the following.
The affirmative form: Verb + mashita
The negative form: Verb + masendeshita

Let’s make some examples.
