EXERCISE 25. Summary: expressing advice and necessity. (Charts 7-7 + 7-9)
Direen'm: Read the passage, and then give advice either in a discussion group or in writing.
Mr. and Mrs. Hill don't know what to do about their fourteen-year-old son, Mark.
He's very intellgent but has no interest in school or in learning. His grades are getting
worse, but he won't do any homework. Sometimes he skips school without
permission, and then he writes an excuse for the school and signs his mother's name.
His older sister, Kathy, is a good student and never causes any problems at home.
Mark's parents keep asking him why he can't be more like Kathy. Kathy makes fun of
Mark's school grades and tells him he's stupid.
AU Mark does when he's home is stay in his room and listen to very loud music.
Sometimes he doesn't even come downstairs to eat meals with his family. He argues
with his parents whenever they ask him to do chores around the house, like taking out
the trash.
Mr. and Mrs. Hill can't stay calm when they talk to him. Mrs. Hill is always
yelling at her son. She nags him constantly to do his chores, clean up his room, finish
his homework, stand up straight, get a haircut, wash his face, and tie his shoes. Mr. Hill
is always making new rules. Some of the rules are unreasonable. For instance, one rule
Mr. Hill made was that his son could not listen to music after five o'clock. Mark often
becomes angry and goes up to his room and slams the door shut.
This family needs a lot of advice. Tell them what changes they should make. What
should Mr. and Mrs. Hill do? What shouldn't they do? What about Kathy? What should
she do? And what's Mark got to do to change his life for the better?
