As the Moon and the Earth are slowly growing further apart, the speed of the Earth’s rotation decreases and days continue to become increasingly longer. 7. Have students finish B3 on page 7. Hardly could I imagine that I would have a whole 48-hour day ahead of me! What will I do with the extra time? Seldom does this opportunity come along, so I am going to make good use of it. I will have a nice game of badminton with my best friend, and we will also have a relaxing picnic in the quiet new park just outside the city. After an 8-hour school day, not only will we need the exercise, but we will also want a break from the busy city life. My plan is to play badminton for an hour, then eat our food and enjoy nature around us for as long as we want. As night-time arrives, we will go back to the city and I am going to have a nice dinner with my parents. Later, I think I will have a 12-hour-long sleep. What a great 48-hour day! So excited am I at the plan that I do not think I will fall asleep tonight! 教学反思： 学科网（北京）股份有限公司 学科网（北京）股份有限公司 $$
