Description(1)- plz correct my note The sun is high up in the sky and it's almost 8 o'clock. But Bob is still sleeping. He seems to be in a nice dream. Being at 8, the clock is ringing noisily. He has just awakened to the sound of clock ringing but he doesn't want to wake up now to see he is covering his ears with hands. Finally, his mom comes in his room. The hands of the clock point already 8:20. "Bob, Time to get up. It's 8:20" Until then, he is covering his ears. "Okay, I don't care whether you are late for your work." And she goes out his room. By then, he wakes up and stretches himself with a yawn something out. “Why she said….. Huh?! Oh my! It’s 8:20!” His eyes are coming out of his head with watching the clock. ‘What should I do first? I have to hurry.’ He is jumping out of his bed and run to a bathroom to take shower. He looks very nervous.
