     "Good evening, everybody!" said the teacher, Donna. "Where is everybody?" That was sort of a daily

joke by Donna. Usually the class started with only two or three students present, and then filled up as the

minutes went by. It was summertime. Summer school was only eight weeks long. Class attendance was

always smaller than during fall and spring semesters.

     "I don't know, teacher. Maybe they late or no come," said one student. "Maybe watching TV football

tonight."

     "Is there a soccer game tonight? It seems like there's a soccer game every night. Oh, well. Let's get

started, okay? We're on page 36 in the workbook. Tonight we're studying participles as adjectives. Students

are always confused when they learn about the present and past participles, so we will practice this a lot.

Tonight, we're just going to practice the present participle.

     "The present participle tells us what emotion or feeling the subject is causing. For example, 'Grammar

is boring' means that the subject-grammar-causes an emotion of boredom. If we say, 'The movie is

interesting,' we are saying that the movie causes a feeling of interest. If we say, 'The roller coaster is exciting,'

we are saying that the roller coaster causes a feeling of excitement. Any questions so far? Am I confusing

you? Is everyone confused?"

     The classroom was quiet. Donna looked at blank faces. They were confused. She knew this would take

a while. But eventually, the faster students would grasp it, and then they would help the slower students. By

the end of the evening, most of the class would feel comfortable using the present participle.

     Donna erased the board and put some new examples on it. She loved guiding her students through difficult

topics like this one. She always felt a little bit thrilled when the look of understanding came to their faces.
