— It's Maggie's.
— She is sitting under a tree.
It's a very nice day in October. The students are having a maths class. But Bob is looking out of the window and watching the clouds move (移动) across the blue sky. "Boy, what a day to play football!" he thinks. Just then(就在那时) the bell rings and wakes(叫醒) him from his daydream(白日梦). He closes his notebook sadly, stands up, and walks slowly to his next class.
