After a week's of  hard work--getting up early every morning, preparing the ssons carefully, supervising the students's extracurricular-learning, i feel tired completely. Today, i don't have  any lesson, so i got up very late in the morning thinking whether my students will do as i asked them to do. Will they do the required exercises every week? will they recite any sample writings? will they make a self-assessment by themselves carefully? ...Oh, i worried a lot. What if they can't satisfy my demands? i was so concerned about their attitude. They didn't have a solid foundation in english, are the demands i made for them beyond their ability? If so, how can i adjust my requirement on them?
