Cause and Effect

Today in the morning, I studied with teacher Usa again. She taught us a new lesson it was " Cause and Effect".
At the first, she taught us in text example before. Then she assigned us to do the practice form by using  Cause and Effect Markers on page 2. The practice was difficult and I can't follow it because I seldom know in the lesson.
Next she assigned us to do "Skill practice exercise 1". I confused about them, I did them with my foolish. When she answered the questions at board, I missed my answers so, I'm bored. Then I did exercise 2, I started to do again by using my brain and review the lesson since I had started to learn, I understood. I could to do my work.
And the last, I did the last exercise for today, it was "The effect of Stress". Although the exercise was very long information but the questions was easy, I could do them. And last assignment for today was conclusion about "The Effect of Stress". I thought, it was easy to do them.
